• Logging in to a website cURL!

  - by uknowho_freeman

  I am using cURL for the first time. I need to login to a site. I have problem with setting cookie file and to retrive, so that i can acces that page not just one time, but several times. I found the code on the web, for logging in to a site and Scrap a page for some detailed info, cause to get that page it takes to much time. so i just want to know if it is OK! the code belove(it is just for login in the code for Scraping its not ready) <?php curl_login('http://mywantedsite.com/login.php','user=******&pass=******','','off'); echo curl_grab_page('http://mywantedsite.com/somepage.php','','off'); function curl_login($url,$data,$proxy,$proxystatus){ $fp = fopen("cookie.txt", "w"); fclose($fp); $login = curl_init(); curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt"); curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt"); curl_setopt($login, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); curl_setopt($login, CURLOPT_TIMEOUT, 40); curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE); if ($proxystatus == 'on') { curl_setopt($login, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($login, CURLOPT_HTTPPROXYTUNNEL, TRUE); curl_setopt($login, CURLOPT_PROXY, $proxy); } curl_setopt($login, CURLOPT_URL, $url); curl_setopt($login, CURLOPT_HEADER, TRUE); curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($login, CURLOPT_POST, TRUE); curl_setopt($login, CURLOPT_POSTFIELDS, $data); ob_start(); // prevent any output return curl_exec ($login); // execute the curl command ob_end_clean(); // stop preventing output curl_close ($login); unset($login); } function curl_grab_page($site,$proxy,$proxystatus){ $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); if ($proxystatus == 'on') { curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE); curl_setopt($ch, CURLOPT_PROXY, $proxy); } curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt"); curl_setopt($ch, CURLOPT_URL, $site); ob_start(); // prevent any output return curl_exec ($ch); // execute the curl command ob_end_clean(); // stop preventing output curl_close ($ch); }

• MEF C# Service - DLL Updating

  - by connerb

  Currently, I have a C# service that runs off of many .dll's and has modules/plugins that it imports at startup. I would like to create an update system that basically stops the service, deletes any files it is told to delete (old versions), downloads new versions from a server, and starts the service. I believe I have coded this right except for the delete part, because as long as I am not overwriting anything, the file will download. If I try to overwrite something, it won't work, which is why I am trying to delete it before hand. However, when I do File.Delete() to the path that I want to do, it gives me access to the path is denied. Here is my code: new Thread(new ThreadStart(() => { ServiceController controller = new ServiceController("client"); controller.Stop(); controller.WaitForStatus(ServiceControllerStatus.Stopped); try { if (um.FilesUpdated != null) { foreach (FilesUpdated file in um.FilesUpdated) { if (file.OldFile != null) { File.Delete(Path.Combine(Utility.AssemblyDirectory, file.OldFile)); } if (file.NewFile != null) { wc.DownloadFile(cs.UpdateUrl + "/updates/client/" + file.NewFile, Path.Combine(Utility.AssemblyDirectory, file.NewFile)); } } } if (um.ModulesUpdated != null) { foreach (ModulesUpdated module in um.ModulesUpdated) { if (module.OldModule != null) { File.Delete(Path.Combine(cs.ModulePath, module.OldModule)); } if (module.NewModule != null) { wc.DownloadFile(cs.UpdateUrl + "/updates/client/modules/" + module.NewModule, Path.Combine(cs.ModulePath, module.NewModule)); } } } } catch (Exception ex) { Logger.log(ex); } controller.Start(); })).Start(); I believe it is because the files are in use, but I can't seem to unload them. I though stopping the service would work, but apparently not. I have also checked the files and they are not read-only (but the folder is, which is located in Program Files, however I couldn't seem to get it to not be read-only programmatically or manually). The service is also being run as an administrator (NT AUTHORITY\SYSTEM). I've read about unloading the AppDomain but AppDomain.Unload(AppDomain.CurrentDomain); returned an exception as well. Not too sure even if this is a problem with MEF or my program just not having the correct permissions...I would assume that it's mainly because the file is in use.

• Enabling Kerberos Authentication for Reporting Services

  - by robcarrol

  Recently, I’ve helped several customers with Kerberos authentication problems with Reporting Services and Analysis Services, so I’ve decided to write this blog post and pull together some useful resources in one place (there are 2 whitepapers in particular that I found invaluable configuring Kerberos authentication, and these can be found in the references section at the bottom of this post). In most of these cases, the problem has manifested itself with the Login failed for User ‘NT Authority\Anonymous’ (“double-hop”) error. By default, Reporting Services uses Windows Integrated Authentication, which includes the Kerberos and NTLM protocols for network authentication. Additionally, Windows Integrated Authentication includes the negotiate security header, which prompts the client to select Kerberos or NTLM for authentication. The client can access reports which have the appropriate permissions by using Kerberos for authentication. Servers that use Kerberos authentication can impersonate those clients and use their security context to access network resources. You can configure Reporting Services to use both Kerberos and NTLM authentication; however this may lead to a failure to authenticate. With negotiate, if Kerberos cannot be used, the authentication method will default to NTLM. When negotiate is enabled, the Kerberos protocol is always used except when: Clients/servers that are involved in the authentication process cannot use Kerberos. The client does not provide the information necessary to use Kerberos. An in-depth discussion of Kerberos authentication is beyond the scope of this post, however when users execute reports that are configured to use Windows Integrated Authentication, their logon credentials are passed from the report server to the server hosting the data source. Delegation needs to be set on the report server and Service Principle Names (SPNs) set for the relevant services. When a user processes a report, the request must go through a Web server on its way to a database server for processing. Kerberos authentication enables the Web server to request a service ticket from the domain controller; impersonate the client when passing the request to the database server; and then restrict the request based on the user’s permissions. Each time a server is required to pass the request to another server, the same process must be used. Kerberos authentication is supported in both native and SharePoint integrated mode, but I’ll focus on native mode for the purpose of this post (I’ll explain configuring SharePoint integrated mode and Kerberos authentication in a future post). Configuring Kerberos avoids the authentication failures due to double-hop issues. These double-hop errors occur when a users windows domain credentials can’t be passed to another server to complete the user’s request. In the case of my customers, users were executing Reporting Services reports that were configured to query Analysis Services cubes on a separate machine using Windows Integrated security. The double-hop issue occurs as NTLM credentials are valid for only one network hop, subsequent hops result in anonymous authentication. The client attempts to connect to the report server by making a request from a browser (or some other application), and the connection process begins with authentication. With NTLM authentication, client credentials are presented to Computer 2. However Computer 2 can’t use the same credentials to access Computer 3 (so we get the Anonymous login error). To access Computer 3 it is necessary to configure the connection string with stored credentials, which is what a number of customers I have worked with have done to workaround the double-hop authentication error. However, to get the benefits of Windows Integrated security, a better solution is to enable Kerberos authentication. Again, the connection process begins with authentication. With Kerberos authentication, the client and the server must demonstrate to one another that they are genuine, at which point authentication is successful and a secure client/server session is established. In the illustration above, the tiers represent the following: Client tier (computer 1): The client computer from which an application makes a request. Middle tier (computer 2): The Web server or farm where the client’s request is directed. Both the SharePoint and Reporting Services server(s) comprise the middle tier (but we’re only concentrating on native deployments just now). Back end tier (computer 3): The Database/Analysis Services server/Cluster where the requested data is stored. In order to enable Kerberos authentication for Reporting Services it’s necessary to configure the relevant SPNs, configure trust for delegation for server accounts, configure Kerberos with full delegation and configure the authentication types for Reporting Services. Service Principle Names (SPNs) are unique identifiers for services and identify the account’s type of service. If an SPN is not configured for a service, a client account will be unable to authenticate to the servers using Kerberos. You need to be a domain administrator to add an SPN, which can be added using the SetSPN utility. For Reporting Services in native mode, the following SPNs need to be registered --SQL Server Service SETSPN -S mssqlsvc/servername:1433 Domain\SQL For named instances, or if the default instance is running under a different port, then the specific port number should be used. --Reporting Services Service SETSPN -S http/servername Domain\SSRS SETSPN -S http/servername.domain.com Domain\SSRS The SPN should be set for the NETBIOS name of the server and the FQDN. If you access the reports using a host header or DNS alias, then that should also be registered SETSPN -S http/www.reports.com Domain\SSRS --Analysis Services Service SETSPN -S msolapsvc.3/servername Domain\SSAS Next, you need to configure trust for delegation, which refers to enabling a computer to impersonate an authenticated user to services on another computer: Location Description Client 1. The requesting application must support the Kerberos authentication protocol. 2. The user account making the request must be configured on the domain controller. Confirm that the following option is not selected: Account is sensitive and cannot be delegated. Servers 1. The service accounts must be trusted for delegation on the domain controller. 2. The service accounts must have SPNs registered on the domain controller. If the service account is a domain user account, the domain administrator must register the SPNs. In Active Directory Users and Computers, verify that the domain user accounts used to access reports have been configured for delegation (the ‘Account is sensitive and cannot be delegated’ option should not be selected): We then need to configure the Reporting Services service account and computer to use Kerberos with full delegation:   We also need to do the same for the SQL Server or Analysis Services service accounts and computers (depending on what type of data source you are connecting to in your reports). Finally, and this is the part that sometimes gets over-looked, we need to configure the authentication type correctly for reporting services to use Kerberos authentication. This is configured in the Authentication section of the RSReportServer.config file on the report server. <Authentication> <AuthenticationTypes>           <RSWindowsNegotiate/> </AuthenticationTypes> <EnableAuthPersistence>true</EnableAuthPersistence> </Authentication> This will enable Kerberos authentication for Internet Explorer. For other browsers, see the link below. The report server instance must be restarted for these changes to take effect. Once these changes have been made, all that’s left to do is test to make sure Kerberos authentication is working properly by running a report from report manager that is configured to use Windows Integrated authentication (either connecting to Analysis Services or SQL Server back-end).

• Twitter traffic might not be what it seems

  - by Piet

  Are you using bit.ly stats to measure interest in the links you post on twitter? I’ve been hearing for a while about people claiming to get the majority of their traffic originating from twitter these days. Now, I’ve been playing with the twitter ruby gem recently, doing various experiments which I’ll not go into detail here because they could be regarded as spamming… if I’d conduct them on a large scale, that is. It’s scary to see people actually engaging with @replies crafted with some regular expressions and eliza-like trickery on status updates found using the twitter api. I’m wondering how Twitter is going to contain the coming spam-flood. When posting links I used bit.ly as url shortener, since this one seems to be the de-facto standard on twitter. A nice thing about bit.ly is that it shows some basic stats about the redirects it performs for your shortened links. To my surprise, most links posted almost immediately resulted in several visitors. Now, seeing that I was posting the links together with some information concerning what the link is about, I concluded that the people who were actually clicking the links should be very targeted visitors. This felt a bit like free adwords, and I suddenly started to understand why everyone was raving about getting traffic from twitter. How wrong I was! (and I think several 1000 online marketers with me) On the destination site I used a traffic logging solution that works by including a little javascript snippet in your pages. It seemed that somehow all visitors disappeared after the bit.ly redirect and before getting to the site, because I was hardly seeing any visitors there. So I started investigating what was happening: by looking at the logfiles of the destination site, and by making my own ’shortened’ urls by doing redirects using a very short domain name I own. This way, I could check the apache access_log before the redirects. Most user agents turned out to be bots without a doubt. Here’s an excerpt of user-agents awk’ed from apache’s access_log for a time period of about one hour, right after posting some links: AideRSS 2.0 (postrank.com) Java/1.6.0_13 Java/1.6.0_14 libwww-perl/5.816 MLBot (www.metadatalabs.com/mlbot) Mozilla/4.0 (compatible;MSIE 5.01; Windows -NT 5.0 - real-url.org) Mozilla/5.0 (compatible; Twitturls; +http://twitturls.com) Mozilla/5.0 (compatible; Viralheat Bot/1.0; +http://www.viralheat.com/) Mozilla/5.0 (Danger hiptop 4.6; U; rv:1.7.12) Gecko/20050920 Mozilla/5.0 (X11; U; Linux i686; en-us; rv:1.9.0.2) Gecko/2008092313 Ubuntu/9.04 (jaunty) Firefox/3.5 OpenCalaisSemanticProxy PycURL/7.18.2 PycURL/7.19.3 Python-urllib/1.17 Twingly Recon twitmatic Twitturly / v0.6 Wget/1.10.2 (Red Hat modified) Wget/1.11.1 (Red Hat modified) Of the few user-agents that seem ‘real’ at first, half are originating from an ip-address used by Amazon EC2. And I doubt people are setting op proxies on there. Oh yeah, Googlebot (the real deal, from a legit google owned address) is sucking up posted links like fresh oysters. I guess google is trying to make sure in advance to never be beaten by twitter in the ‘realtime search’ department. Actually, I think it’d be almost stupid NOT to post any new pages/posts/websites on Twitter, it must be one of the fastest ways to get a Googlebot visit. Same experiment with a real, established twitter account Now, because I was posting the url’s either as ’status’ messages or directed @people, on a test-account with hardly any (human) followers, I checked again using the twitter accounts from a commercial site I’m involved with. These accounts all have between 500 and 1000 targeted (I think) followers. I checked the destination access_logs and also added ‘my’ redirect after the bit.ly redirect: same results, although seemingly a bit higher real visitor/bot ratio. Btw: one of these account was ‘punished’ with a 1 week lock recently because the same (1 one!) status update was sent that was sent right before using another account. They got an email explaining the lock because the account didn’t act according to their TOS. I can’t find anything in their TOS about it, can you? I don’t think Twitter is on the right track punishing a legit account, knowing the trickery I had been doing with it’s api went totally unpunished. I might be wrong though, I often am. On the other hand: this commercial site reported targeted traffic and actual signups from visitors coming from Twitter. The ones that are really real visitors are also very targeted. I’m just not sure if the amount of work involved could hold up against an adwords campaign. Reposting the same link over and over again helps On thing I noticed: It helps to keep on reposting the same links with regular intervals. I guess most people only look at their first page when checking out recent posts of the ones they’re following, or don’t look too far back when performing a search. Now, this probably isn’t according to the twitter TOS. Actually, it might be spamming but no-one is obligated to follow anyone else of course. This way, I was getting more real visitors and less bots. To my surprise (when my programmer’s hat is on) there were still repeated visits from the same bots coming from the same ip-addresses. Did they expect to find something else when visiting for a 2nd or 3rd time? (actually,this gave me an idea: you can’t change a link once it’s posted, but you can change where it redirects to) Most bots were smart enough not to follow the same link again though. Are you successful in getting real visitors from Twitter? Are you only relying on bit.ly to provide traffic stats?

• DNS lookup failures while accessing my website some proxy error

  - by Bond

  Here is a situation until today morning,every thing has been working perfectly fine with me. From past 6 months many of my domains wer accessible as http://site1.myserver.com http://site2.myserver.com http://site3.myserver.com http://site4.myserver.com All these were Reverse Proxy configurations. I have some applications on each of them. until today morning some people reported me that http://site1.myserver.com/app1 is not working but http://site1.myserver.com is accessible but http://site2.myserver.com is accessible but http://site3.myserver.com is accessible but http://site4.myserver.com not accessible In past 6 months I have not changed any of these Apache configurations (things were working perfectly so) The error which can be seen in browser are while accessing http://site1.myserver.com/app1 Proxy Error The proxy server received an invalid response from an upstream server.

• Change or Reset Windows Password from a Ubuntu Live CD

  - by Trevor Bekolay

  If you can’t log in even after trying your twelve passwords, or you’ve inherited a computer complete with password-protected profiles, worry not – you don’t have to do a fresh install of Windows. We’ll show you how to change or reset your Windows password from a Ubuntu Live CD. This method works for all of the NT-based version of Windows – anything from Windows 2000 and later, basically. And yes, that includes Windows 7. You’ll need a Ubuntu 9.10 Live CD, or a bootable Ubuntu 9.10 Flash Drive. If you don’t have one, or have forgotten how to boot from the flash drive, check out our article on creating a bootable Ubuntu 9.10 flash drive. The program that lets us manipulate Windows passwords is called chntpw. The steps to install it are different in 32-bit and 64-bit versions of Ubuntu. Installation: 32-bit Open up Synaptic Package Manager by clicking on System at the top of the screen, expanding the Administration section, and clicking on Synaptic Package Manager. chntpw is found in the universe repository. Repositories are a way for Ubuntu to group software together so that users are able to choose if they want to use only completely open source software maintained by Ubuntu developers, or branch out and use software with different licenses and maintainers. To enable software from the universe repository, click on Settings > Repositories in the Synaptic window. Add a checkmark beside the box labeled “Community-maintained Open Source software (universe)” and then click close. When you change the repositories you are selecting software from, you have to reload the list of available software. In the main Synaptic window, click on the Reload button. The software lists will be downloaded. Once downloaded, Synaptic must rebuild its search index. The label over the text field by the Search button will read “Rebuilding search index.” When it reads “Quick search,” type chntpw in the text field. The package will show up in the list. Click on the checkbox near the chntpw name. Click on Mark for Installation. chntpw won’t actually be installed until you apply the changes you’ve made, so click on the Apply button in the Synaptic window now. You will be prompted to accept the changes. Click Apply. The changes should be applied quickly. When they’re done, click Close. chntpw is now installed! You can close Synaptic Package Manager. Skip to the section titled Using chntpw to reset your password. Installation: 64-bit The version of chntpw available in Ubuntu’s universe repository will not work properly on a 64-bit machine. Fortunately, a patched version exists in Debian’s Unstable branch, so let’s download it from there and install it manually. Open Firefox. Whether it’s your preferred browser or not, it’s very readily accessible in the Ubuntu Live CD environment, so it will be the easiest to use. There’s a shortcut to Firefox in the top panel. Navigate to http://packages.debian.org/sid/amd64/chntpw/download and download the latest version of chntpw for 64-bit machines. Note: In most cases it would be best to add the Debian Unstable branch to a package manager, but since the Live CD environment will revert to its original state once you reboot, it’ll be faster to just download the .deb file. Save the .deb file to the default location. You can close Firefox if desired. Open a terminal window by clicking on Applications at the top-left of the screen, expanding the Accessories folder, and clicking on Terminal. In the terminal window, enter the following text, hitting enter after each line: cd Downloadssudo dpkg –i chntpw* chntpw will now be installed. Using chntpw to reset your password Before running chntpw, you will have to mount the hard drive that contains your Windows installation. In most cases, Ubuntu 9.10 makes this simple. Click on Places at the top-left of the screen. If your Windows drive is easily identifiable – usually by its size – then left click on it. If it is not obvious, then click on Computer and check out each hard drive until you find the correct one. The correct hard drive will have the WINDOWS folder in it. When you find it, make a note of the drive’s label that appears in the menu bar of the file browser. If you don’t already have one open, start a terminal window by going to Applications > Accessories > Terminal. In the terminal window, enter the commands cd /medials pressing enter after each line. You should see one or more strings of text appear; one of those strings should correspond with the string that appeared in the title bar of the file browser earlier. Change to that directory by entering the command cd <hard drive label> Since the hard drive label will be very annoying to type in, you can use a shortcut by typing in the first few letters or numbers of the drive label (capitalization matters) and pressing the Tab key. It will automatically complete the rest of the string (if those first few letters or numbers are unique). We want to switch to a certain Windows directory. Enter the command: cd WINDOWS/system32/config/ Again, you can use tab-completion to speed up entering this command. To change or reset the administrator password, enter: sudo chntpw SAM SAM is the file that contains your Windows registry. You will see some text appear, including a list of all of the users on your system. At the bottom of the terminal window, you should see a prompt that begins with “User Edit Menu:” and offers four choices. We recommend that you clear the password to blank (you can always set a new password in Windows once you log in). To do this, enter “1” and then “y” to confirm. If you would like to change the password instead, enter “2”, then your desired password, and finally “y” to confirm.

• mono 3.0.2 + xsp + lighttpd delivers empty page

  - by Nefal Warnets

  I needed MVC 4 (and basic .NET 4.5) support so I downloaded mono 3.0.2 and deployed it on an lighttpd 1.4.28 installation, together with xsp-2.10.2 (was the latest I could find). After going through the config tutorials I managed to get the fastcgi server to spawn, but all pages are served empty. even if I go to nonexistant urls or direct .aspx files I get an empty HTTP 200 response. The log file on Debug shows nothing suspicious. Here is the log: [2012-12-12 15:15:38Z] Debug Accepting an incoming connection. [2012-12-12 15:15:38Z] Debug Record received.

• svnstat script

  - by Kyle Hodgson

  So I'm building out a shell script to check out all of our relevant svn repositories for analysis in svnstat. I've gotten all of this to work manually, now I'm writing up a bash script in cygwin on my Vista laptop, as I intend to move this to a Linux server at some point. Edit: I gave up on this and wrote a simple .bat script. I'll figure out the Linux deployment some other way. Edit: added the sleep 30 and svn log commands. I can tell now, with the svn log command, that it's not getting to the svn log ... this time, it did Applications, and ran the log, and then check out Database, and froze. I'll put the sleep 30 before and after the log this time. co2.sh #!/bin/bash function checkout { mkdir $1 svn checkout svn://dev-server/$1 $1 svn log --verbose --xml >> svn.log $1 sleep 30 } cd /cygdrive/c/Users/My\ User/Documents/Repos/wc checkout Applications checkout Database checkout WebServer/www.mysite.com checkout WebServer/anotherhost.mysite.com checkout WebServer/AnotherApp checkout WebServer/thirdhost.mysite.com checkout WebServer/fourthhost.mysite.com checkout WebServer/WebServices It works, for the most part - but for some reason it has a tendency to stop working after a few repositories, usually right after finishing a repository before going to the next one. When it fails, it will not recover on its own. I've tried commenting out the svn line, it goes in and creates all the directories just fine when I do that - so its not that. I'm looking for direction as well as direct advice. Cygwin has been very stable for me, but I did start using the native rxvt instead of "bash in a cmd.exe window" recently. I don't think that's the problem, as I've left top on remote systems running all night and rxvt didn't seem to mind. Also I haven't done any bash scripting in cygwin so I suppose this might not be recommended; though I can't see why not. I don't want all of WebServer, hence me only checking out certain folders like that. What I suspect is that something is hanging up the svn checkout. Any ideas here? Edit: this time when I hit ctrl+z to cancel out, I forgot I was on Windows and typed ps to see if the job was still running; and as you can see there are lots of svn processes hanging around... strange.

• Windows Backup fails with 0x80070002: "The system cannot find the file specified"

  - by James Johnston

  Windows 7 Backup is failing. When backing up even a single insignificant directory (e.g. I chose only the empty "Contacts" directory, leaving all other directories unchecked), I get this error within a few seconds and the backup fails. If I uncheck all files/directories, and just do the system image - then the system image is backed up OK without issue. Backup destination is an external USB hard drive. Steps to reproduce and subsequent failure: Set up backup to go to external hard drive. Don't back up system image. Back up "Contacts" directory only for my profile. Start backup. Immediately view the status of the backup, it stays on "Creating a shadow copy..." for a few seconds, and then the backup fails. Click Options button, and it says "Check your backup / The system cannot find the file specified." - with options to "Try to run backup again" or "Change backup settings". If I click "Show Details", then it says: Backup time: 4/12/2012 04:38 Backup location: My Book (D:) Error code: 0x80070002 An examination of the Event Log shows nothing useful beyond the following: Log Name: Application Source: Windows Backup Date: 4/12/2012 04:38:44 Event ID: 4104 Task Category: None Level: Error Keywords: Classic User: N/A Computer: JTJLaptop Description: The backup was not successful.

Running SFC /SCANNOW to run system file checker Checked the list of profiles at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and ensured that each profile directory exists. I'm stumped; WHAT file can't be found and why is my backup failing? This is on a Lenovo T420 laptop.

• The DOS DEBUG Environment

  - by MarkPearl

  Today I thought I would go back in time and have a look at the DEBUG command that has been available since the beginning of dawn in DOS, MS-DOS and Microsoft Windows. up to today I always knew it was there, but had no clue on how to use it so for those that are interested this might be a great geek party trick to pull out when you want the awe the younger generation and want to show them what “real” programming is about. But wait, you will have to do it relatively quickly as it seems like DEBUG was finally dumped from the Windows group in Windows 7. Not to worry, pull out that Windows XP box which will get you even more geek points and you can still poke DEBUG a bit. So, for those that are interested and want to find out a bit about the history of DEBUG read the wiki link here. That all put aside, lets get our hands dirty.. How to Start DEBUG in Windows Make sure your version of Windows supports DEBUG. Open up a console window Make a directory where you want to play with debug – in my instance I called it C221 Enter the directory and type Debug You will get a response with a – as illustrated in the image below…   The commands available in DEBUG There are several commands available in DEBUG. The most common ones are A (Assemble) R (Register) T (Trace) G (Go) D (Dump or Display) U (Unassemble) E (Enter) P (Proceed) N (Name) L (Load) W (Write) H (Hexadecimal) I (Input) O (Output) Q (Quit) I am not going to cover all these commands, but what I will do is go through a few of them briefly. A is for Assemble Command (to write code) The A command translates assembly language statements into machine code. It is quite useful for writing small assembly programs. Below I have written a very basic assembly program. The code typed out is as follows mov ax,0015 mov cx,0023 sub cx,ax mov [120],al mov cl,[120]A nop R is for Register (to jump to a point in memory) The r command turns out to be one of the most frequent commands you will use in DEBUG. It allows you to view the contents of registers and to change their values. It can be used with the following combinations… R – Displays the contents of all the registers R f – Displays the flags register R register_name – Displays the contents of a specific register All three methods are illustrated in the image above T is for Trace (To execute a program step by step) The t command allows us to execute the program step by step. Before we can trace the program we need to point back to the beginning of the program. We do this by typing in r ip, which moves us back to memory point 100. We then type trace which executes the first line of code (line 100) (As shown in the image below starting from the red arrow). You can see from the above image that the register AX now contains 0015 as per our instruction mov ax,0015 You can also see that the IP points to line 0103 which has the MOV CX,0023 command If we type t again it will now execute the second line of the program which moves 23 in the cx register. Again, we can see that the line of code was executed and that the CX register now holds the value of 23. What I would like to highlight now is the section underlined in red. These are the status flags. The ones we are going to look at now are 1st (NV), 4th (PL), 5th (NZ) & 8th (NC) NV means no overflow, the alternate would be OV PL means that the sign of the previous arithmetic operation was Plus, the alternate would be NG (Negative) NZ means that the results of the previous arithmetic operation operation was Not Zero, the alternate would be ZR NC means that No final Carry resulted from the previous arithmetic operation. CY means that there was a final Carry. We could now follow this process of entering the t command until the entire program is executed line by line. G is for Go (To execute a program up to a certain line number) So we have looked at executing a program line by line, which is fine if your program is minuscule BUT totally unpractical if we have any decent sized program. A quicker way to run some lines of code is to use the G command. The ‘g’ command executes a program up to a certain specified point. It can be used in connection with the the reset IP command. You would set your initial point and then run the G command with the line you want to end on. P is for Proceed (Similar to trace but slightly more streamlined) Another command similar to trace is the proceed command. All that the p command does is if it is called and it encounters a CALL, INT or LOOP command it terminates the program execution. In the example below I modified our example program to include an int 20 at the end of it as illustrated in the image below… Then when executing the code when I encountered the int 20 command I typed the P command and the program terminated normally (illustrated below). D is for Dump (or for those more polite Display) So, we have all these assembly lines of code, but if you have ever opened up an exe or com file in a text/hex editor, it looks nothing like assembly code. The D command is a way that we can see what our code looks like in memory (or in a hex editor). If we examined the image above, we can see that Debug is storing our assembly code with each instruction following immediately after the previous one. For instance in memory address 110 we have int and 111 we have 20. If we examine the dump of memory we can see at memory point 110 CD is stored and at memory point 111 20 is stored. U is for Unassemble (or Convert Machine code to Assembly Code) So up to now we have gone through a bunch of commands, but probably one of the most useful is the U command. Let’s say we don’t understand machine code so well and so instead we want to see it in its equivalent assembly code. We can type the U command followed by the start memory point, followed by the end memory point and it will show us the assembly code equivalent of the machine code. E is for a bunch of things… The E command can be used for a bunch of things… One example is to enter data or machine code instructions directly into memory. It can also be used to display the contents of memory locations. I am not going to worry to much about it in this post. N / L / W is for Name, Load & Write So we have written out assembly code in debug, and now we want to save it to disk, or write it as a com file or load it. This is where the N, L & W command come in handy. The n command is used to give a name to the executable program file and is pretty simple to use. The w command is a bit trickier. It saves to disk all the memory between point bx and point cx so you need to specify the bx memory address and the cx memory address for it to write your code. Let’s look at an example illustrated below. You do this by calling the r command followed by the either bx or cx. We can then go to the directory where we were working and will see the new file with the name we specified. The L command is relatively simple. You would first specify the name of the file you would like to load using the N command, and then call the L command. Q is for Quit The last command that I am going to write about in this post is the Q command. Simply put, calling the Q command exits DEBUG. Commands we did not Cover Out of the standard DEBUG commands we covered A, T, G, D, U, E, P, R, N, L & W. The ones we did not cover were H, I & O – I might make mention of these in a later post, but for the basics they are not really needed. Some Useful Resources Please note this post is based on the COS2213 handouts for UNISA A Guide to DEBUG - http://mirror.href.com/thestarman/asm/debug/debug.htm#NT

• Users suddenly missing write permissions to the root drive c within an active directory domain

  - by Kevin

  I'm managing an active directory single domain environment on some Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012 machines. Since a few weeks I got a strange issue. Some users (not all!) report that they cannot any longer save, copy or write files to the root drive c, whether on their clients (vista, win 7) nor via remote desktop connection on a Windows Server 2008 machine. Even running programs that require direct write permissions to the root drive without administrator permissions fail to do so since then. The affected users have local administrator permissions. The question I'm facing now is: What caused this change of system behavior? Why did this happen? I didn't find out yet. What was the last thing I did before it happened? The last action that was made before it happened was the rollout of a GPO containing network drive mappings for the users depending on their security group membership. All network drives are located on a linux server with samba enabled. We did not change any UAC settings, and they have always been activated. However I can't imagine that rolling out this GPO caused the problem. Has anybody faced an issue like that? Just in case: I know that it is for a specific reason that an user without administrative privileges is prevented from writing to the root drive since windows vista and the implementation of UAC. I don't think that those users should be able to write to drive c, but I try to figure out why this is happening and a few weeks ago this was still working. I also know that a user who is a member of the local administrators group does not execute anything with administrator permissions per default unless he or she executes a program with this permissions. What did I do yet? I checked the permissions of the affected programs, the affected clients/server. Didn't find something special. I checked ALL of our GPOs if there exist any restrictions that could prevent the affected users from writing to the root drive. Did not find any settings. I checked the UAC settings of the affected users and compared those to other users that still can write to the root drive. Everything similar. I googled though the internet and tried to find someone who had a similar problem. Did not find one. Has anybody an idea? Thank you very much. Edit: The GPO that was rolled out does the following (Please excuse if the settings are not named exactly like that, I translated the settings into english): **Windows Settings -- Network Drive Mappings -- Drive N: -- General:** Action: Replace **Properties:** Letter: N Location: \\path-to-drive\drivename Re-Establish connection: deactivated Label as: Name_of_the_Share Use first available Option: deactivated **Windows Settings -- Network Drive Mappings -- Drive N: -- Public: Options:** On error don't process any further elements for this extension: no Run as the logged in user: no remove element if it is not applied anymore: no Only apply once: no **Securitygroup:** Attribute -- Value bool -- AND not -- 0 name -- domain\groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 **Securitygroup:** Attribute -- Value bool -- OR not -- 0 name -- domain\another-groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 Edit: The Error-Message of an affected users says the following: Due to an unexpected error you can't copy the file. Error-Code 0x80070522: The client is missing a required permission. The command icacls C: shows the following: NT-AUTORITY\SYSTEM:(OI)(CI)(F) PRE-DEFINED\Administrators:(OI)(CI)(F) computername\username:(OI)(CI)(F) A college just told me that also the primary domain-controller (PDC) changed from Windows Server 2008 to Windows Server 2012. That also may be a reason. Any suggestions?

• NTFS Permissions - Access Denied even though Explicit Allow and no Deny

  - by chris613

  I'm hoping someone can help me with this NTFS permissions problem. The short version is that I can't write a new file in F:\SomeDir even though I seem to be granted full permissions via both the "Domain Admins" group and a second unprivileged group. The "Effective Permissions" tab in the explorer permissions UI shows that I have full control, and there are no "Deny"s anywhere in the ACL or anything else that looks unusual. I am logged into the machine over RDP and accessing the disk directly, not through a share. F:\SomeDir>set U USERDNSDOMAIN=THEOFFICE.LOCAL USERDOMAIN=THEOFFICE USERNAME=thisisme USERPROFILE=C:\Users\thisisme F:\SomeDir>icacls . . BUILTIN\Administrators:(I)(F) CREATOR OWNER:(I)(OI)(CI)(IO)(F) THEOFFICE\Domain Admins:(I)(OI)(CI)(F) NT AUTHORITY\SYSTEM:(I)(OI)(CI)(F) BUILTIN\Administrators:(I)(OI)(CI)(IO)(F) BUILTIN\Users:(I)(OI)(CI)(RX) Successfully processed 1 files; Failed processing 0 files F:\SomeDir>net group /domain "Domain Admins" The request will be processed at a domain controller for domain THEOFFICE.local. Group name Domain Admins Comment Designated administrators of the domain Members ------------------------------------------------------------------------------- Administrator thatguy thisisme The command completed successfully. F:\SomeDir>echo "whyUNoCreateFile?" > whyUNoCreateFile.txt Access is denied. I searched for answers and came across similar problems that lead to UAC (ex. Why does removing the EVERYONE group prevent domain admins from accessing a drive? ). I can't turn off UAC at the moment, so I try a "regular" group that I'm also part of. This group has no special rights assignments and is not part of any administrative groups. Still no dice: [***** This one command executed in an elevated shell *****] F:\SomeDir>icacls . /grant THEOFFICE\iteveryone:(OI)(CI)F processed file: . Successfully processed 1 files; Failed processing 0 files F:\SomeDir>net group /domain "iteveryone" The request will be processed at a domain controller for domain THEOFFICE.local. Group name ITeveryone Comment Members ------------------------------------------------------------------------------- Administrator thatguy thisisme otherguy someitguy The command completed successfully. F:\ScanningVMsForIBM>echo y > u Access is denied. As you can see, using a "regular" group didn't help. I have logged out and back in to the server to ensure my login token is up to date, and at any rate I belonged to these groups before the server was created. If I grant explicit permission to myself, it does allow me to write files: [***** This one command executed in an elevated shell *****] F:\SomeDir>icacls . /grant THEOFFICE\thisisme:(OI)(CI)F processed file: . Successfully processed 1 files; Failed processing 0 files F:\SomeDir>echo y > u F:\SomeDir>type u y My requirement is for the "Domain Admins" group to have Full Control, or if that's not possible without disabling UAC, then a second group will do, but I can't get either to work. I'm really stumped. Can someone please point out what I could be overlooking?

• Windows Azure Virtual Machine Readiness and Capacity Assessment for SQL Server

  - by SQLOS Team

  Windows Azure Virtual Machine Readiness and Capacity Assessment for Windows Server Machine Running SQL Server With the release of MAP Toolkit 8.0 Beta, we have added a new scenario to assess your Windows Azure Virtual Machine Readiness. The MAP 8.0 Beta performs a comprehensive assessment of Windows Servers running SQL Server to determine you level of readiness to migrate an on-premise physical or virtual machine to Windows Azure Virtual Machines. The MAP Toolkit then offers suggested changes to prepare the machines for migration, such as upgrading the operating system or SQL Server. MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys. Now, let’s walk through the MAP Toolkit task for completing the Windows Azure Virtual Machine assessment and capacity planning. The tasks include the following: Perform an inventory View the Windows Azure VM Readiness results and report Collect performance data for determine VM sizing View the Windows Azure Capacity results and report Perform an inventory: 1. To perform an inventory against a single machine or across a complete environment, choose Perform an Inventory to launch the Inventory and Assessment Wizard as shown below: 2. After the Inventory and Assessment Wizard launches, select either the Windows computers or SQL Server scenario to inventory Windows machines. HINT: If you don’t care about completely inventorying a machine, just select the SQL Server scenario. Click Next to Continue. 3. On the Discovery Methods page, select how you want to discover computers and then click Next to continue. Description of Discovery Methods: Use Active Directory Domain Services -- This method allows you to query a domain controller via the Lightweight Directory Access Protocol (LDAP) and select computers in all or specific domains, containers, or OUs. Use this method if all computers and devices are in AD DS. Windows networking protocols --  This method uses the WIN32 LAN Manager application programming interfaces to query the Computer Browser service for computers in workgroups and Windows NT 4.0–based domains. If the computers on the network are not joined to an Active Directory domain, use only the Windows networking protocols option to find computers. System Center Configuration Manager (SCCM) -- This method enables you to inventory computers managed by System Center Configuration Manager (SCCM). You need to provide credentials to the System Center Configuration Manager server in order to inventory the managed computers. When you select this option, the MAP Toolkit will query SCCM for a list of computers and then MAP will connect to these computers. Scan an IP address range -- This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. Note: This option can perform poorly, if many IP addresses aren’t being used within the range. Manually enter computer names and credentials -- Use this method if you want to inventory a small number of specific computers. Import computer names from a files -- Using this method, you can create a text file with a list of computer names that will be inventoried. 4. On the All Computers Credentials page, enter the accounts that have administrator rights to connect to the discovered machines. This does not need to a domain account, but needs to be a local administrator. I have entered my domain account that is an administrator on my local machine. Click Next after one or more accounts have been added. NOTE: The MAP Toolkit primarily uses Windows Management Instrumentation (WMI) to collect hardware, device, and software information from the remote computers. In order for the MAP Toolkit to successfully connect and inventory computers in your environment, you have to configure your machines to inventory through WMI and also allow your firewall to enable remote access through WMI. The MAP Toolkit also requires remote registry access for certain assessments. In addition to enabling WMI, you need accounts with administrative privileges to access desktops and servers in your environment. 5. On the Credentials Order page, select the order in which want the MAP Toolkit to connect to the machine and SQL Server. Generally just accept the defaults and click Next. 6. On the Enter Computers Manually page, click Create to pull up at dialog to enter one or more computer names. 7. On the Summary page confirm your settings and then click Finish. After clicking Finish the inventory process will start, as shown below: Windows Azure Readiness results and report After the inventory progress has completed, you can review the results under the Database scenario. On the tile, you will see the number of Windows Server machine with SQL Server that were analyzed, the number of machines that are ready to move without changes and the number of machines that require further changes. If you click this Azure VM Readiness tile, you will see additional details and can generate the Windows Azure VM Readiness Report. After the report is generated, select View | Saved Reports and Proposals to view the location of the report. Open up WindowsAzureVMReadiness* report in Excel. On the Windows tab, you can see the results of the assessment. This report has a column for the Operating System and SQL Server assessment and provides a recommendation on how to resolve, if there a component is not supported. Collect Performance Data Launch the Performance Wizard to collect performance information for the Windows Server machines that you would like the MAP Toolkit to suggest a Windows Azure VM size for. Windows Azure Capacity results and report After the performance metrics are collected, the Azure VM Capacity title will display the number of Virtual Machine sizes that are suggested for the Windows Server and Linux machines that were analyzed. You can then click on the Azure VM Capacity tile to see the capacity details and generate the Windows Azure VM Capacity Report. Within this report, you can view the performance data that was collected and the Virtual Machine sizes.   MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys.

• gallery2 and nginx with rewrite return file not found for file name with space (or + sign in url)

  - by Vangel

  I have setup nginx with gallery2 on an internal server. Everything works fine under apache2 which I checked first, it used to be on apache2 Problem is: gallery2 seems to generate url with + sign in it for file names/ images which had spaces in it so a file like "may report.jpg" becomes "may+report.jpg" The URL rewrite works but gallery2 throws an error for file not found. THis does not happen under apache2. Here is my nginx rewrite rule: location / { index main.php index.html; default_type text/html; # If the file exists as a static file serve it # directly without running all # the other rewite tests on it if (-f $request_filename) { break; } } location /v/ { # if ($request_uri !~ /main.php) # { rewrite ^/v/(.*)$ /main.php?g2_view=core.ShowItem&g2_path=$1 last; # } } location /d/ { if ($request_uri !~ /main.php) { rewrite ^/d/([0-9]+)-([0-9]+)/(.*)$ /main.php?g2_view=core.DownloadItem&g2_itemId=$1&g2_serialNumber=$2&g2_fileName=$3 last; } } location ~ \.php$ { fastcgi_pass 127.0.0.1:8889; fastcgi_index main.php; fastcgi_intercept_errors on; # to support 404s for PHP files not found fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; fastcgi_param SERVER_NAME $host; fastcgi_read_timeout 300; } the sit on its own works fine. only the images with spaces in file name do not display in album view and also when clicking the the image for full page view will throw this error Error (ERROR_MISSING_OBJECT) : Parent 103759 path report+april+456.flv in modules/core/classes/helpers/GalleryFileSystemEntityHelper_simple.class at line 98 (GalleryCoreApi::error) in modules/core/classes/GalleryCoreApi.class at line 1853 (GalleryFileSystemEntityHelper_simple::fetchChildIdByPathComponent) in modules/core/classes/helpers/GalleryFileSystemEntityHelper_simple.class at line 53 (GalleryCoreApi::fetchChildIdByPathComponent) in modules/core/classes/GalleryCoreApi.class at line 1804 (GalleryFileSystemEntityHelper_simple::fetchItemIdByPath) in modules/rewrite/classes/RewriteSimpleHelper.class at line 45 (GalleryCoreApi::fetchItemIdByPath) in ??? at line 0 (RewriteSimpleHelper::loadItemIdFromPath) in modules/rewrite/classes/RewriteUrlGenerator.class at line 103 in modules/rewrite/classes/parsers/modrewrite/ModRewriteUrlGenerator.class at line 37 (RewriteUrlGenerator::_onLoad) in init.inc at line 147 (ModRewriteUrlGenerator::initNavigation) in main.php at line 180 in main.php at line 94 in main.php at line 83 System Information Gallery version 2.2.4 PHP version 5.3.6 fpm-fcgi Webserver nginx/0.8.55 Database mysqli 5.0.95 Toolkits ImageMagick, Thumbnail, Gd Operating system Linux CentOS-55-64-minimal 2.6.18-274.18.1.el5 #1 SMP Thu Feb 9 12:45:44 EST 2012 x86_64 Browser Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5 In the report above there is usable system information if that helps. I know the nginx is old but it comes as default in centos repo and I am not sure if upgrading will fix the problem or break something else it seems gallery2 must map the + to space internally but why it's not doing so with nginx I can't tell. EDIT: I just verified that if I change the '+' sign to %20 then gallery2 works. but gallery2 is generating URL as +. I found a (maybe) related problem here for IIS7 and Gallery2 http://forums.asp.net/t/1431951.aspx EDIT2: Accessing the URL without rewrite and having the + sign works. Must be something to do with rewrite. Here is the relevant apache2 rule that might be of help RewriteCond %{THE_REQUEST} /d/([0-9]+)-([0-9]+)/([^/?]+)(\?.|\ .)

• SQLExpress service unable to start Error code 17053

  - by Chris Sobolewski

  A user was instructed by their software support to upgrade a program and install SQLExpress as part of the installation process. Since that time, the service has been able to start, citing error 17053, which appears to be an authentication issue.

• Apache access.log interpretation

  - by Pantelis Sopasakis

  In the log file of apache (access.log) I find log entries like the following: 10.20.30.40 - - [18/Mar/2011:02:12:44 +0200] "GET /index.php HTTP/1.1" 404 505 "-" "Opera/9.80 (Windows NT 6.1; U; en) Presto/2.7.62 Version/11.01" Whose meaning is clear: The client with IP 10.20.30.40 applied a GET HTTP method on /index.php (that is to say http://mysite.org/index.php) receiving a status code 404 using Opera as client/browser. What I don't understand is entries like the following: 174.34.231.19 - - [18/Mar/2011:02:24:56 +0200] "GET http://www.siasatema.com HTTP/1.1" 200 469 "-" "Python-urllib/2.4" So here what I see is that someone (client with IP 174.34.231.19) accessed http://www.siasatema.com and got a 200 HTTP status code(?). It doesn't make sense to me... the only interpretation I can think of is that my apache server acts like proxy! Here are some other requests that don't have my site as destination... 187.35.50.61 - - [18/Mar/2011:01:28:20 +0200] "POST http://72.26.198.222:80/log/normal/ HTTP/1.0" 404 491 "-" "Octoshape-sua/1010120" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "CONNECT 64.12.244.203:80 HTTP/1.0" 405 556 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "open 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:04 +0200] "telnet 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:09 +0200] "64.12.244.203 80" 400 301 "-" "-" I believe that all these are related to some kind of attack or abuse of the server. Could someone explain to may what is going on and how to cope with this situation? Update 1: I disabled mod_proxy to make sure that I don't have an open proxy: # a2dismod proxy Where from I got the message: Module proxy already disabled I made sure that there is no file proxy.conf under $APACHE/mods-enabled. Finally, I set on my browser (Mozzila) my IP as a proxy and tried to access http://google.com. I was not redirected to google.com but instead my web page appeared. The same happened with trying to access http://a.b (!). So my server does not really work as a proxy since it does not forward the requests... But I think it would be better if somehow I could configure it to return a status code 403. Here is my apache configuration file: <VirtualHost *:80> ServerName mysite.org ServerAdmin webmaster@localhost DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost> Update 2: Using a block, I restrict the use of other methods than GET and POST... <Limit POST PUT CONNECT HEAD OPTIONS DELETE PATCH PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK> Order deny,allow Deny from all </Limit> <LimitExcept GET> Order deny,allow Deny from all </LimitExcept> Now methods other that GET are forbidden (403). My only question now is whether there is some trick to boot those how try to use my server as a proxy out...

• Why does Google mark one e-mail as spam while does not the other?

  - by nKn

  I've a Postfix installation which works fine, I don't get any trouble with mails sent through a mail client (in my case, Thunderbird or RoundCube) when the To: address is a GMail account. However, I recently needed to use the PHPMailer tool to send some e-mails to some GMail accounts, so I configured an account to be used via SASL authentication + TLS. I don't mean mass mailing, just 2-3 mails. If I send the e-mail from the Thunderbird or RoundCube clients, the mail is not marked as spam. However, if I use PHPMailer, it always gets catalogued as spam. So I compared both headers and I just can't find the reason why the second is marked as spam while the first one is just ok. The first header sent from a mail client which is not marked as spam: Delivered-To: [email protected] Received: by 10.76.153.102 with SMTP id vf6csp230573oab; Tue, 19 Aug 2014 11:08:19 -0700 (PDT) X-Received: by 10.60.23.39 with SMTP id j7mr45544050oef.20.1408471699715; Tue, 19 Aug 2014 11:08:19 -0700 (PDT) Return-Path: <[email protected]> Received: from mail.mydomain.com (X.ip-92-222-X.eu.

Is there some significant difference which is making the second e-mail to be marked as spam by Google?

• Troubleshooting Website problems within the local network

  - by HaydnWVN

  Have an external website which opens fine on some PC's, yet seems to time out (or symptoms of timing out, but never actually does) on others. Seems to only affect (some) of our newer HP Pro 3305 MT Workstations. All of which are running Win7 32bit SP1 with all updates. Older PC's (Win7 32bit SP1 & WinXP) are unaffected. Using Google Chrome & Firefox makes no difference. Opening the website in IE9 Compatibility Mode has exactly the same symptoms. All PC's are on the same local network (Workgroup) using the same DNS server & gateway (inhouse) on the same internet connection, on the same subnet. There is no proxy server, no content filtering, no load balancing etc etc. Only group policy in effect (locally) is for Update scheduling. Local firewalls are all the same (Kaspersky WP4) and our external facing firewall has no IP specific settings. I have no control over the external website, traceroute shows the same destination on all PC's. It is a fairly popular website in our industry (Horticulture) and i'm not aware of any other people (even other sites within our sister companies) with the same problem. Update: Used Fiddler2 to monitor the HTTP request, seems its not getting fulfilled for some reason?! Request sent: GET http://www.rhs.org.uk/ HTTP/1.1 Host: www.rhs.org.uk Connection: keep-alive User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.47 Safari/536.11 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Log from Fiddler 2 of the request: This session is not yet complete.

• How to get ISA 2006 Web Proxy to work with the Single Network Adapter template

  - by tronda

  I need to test an issue with running our application behind a proxy server with different type of configurations, so I installed ISA 2006 Enterprise on a desktop computer. Since this computer only has a single network card and I want to start out easy, I chose the "Single Network Adapter" template. We have a internal NAT'ed network which is in the 10 range. I have defined the internal network on the ISA server to be 10.XXX.YY.1 - 10.XXX.YY.255 I also have the Default rule which denies all traffic, but I've added the following Rule: Policy - Protocols - From - To Accept HTTP Internal External HTTPS Local Host Internal HTTS Server Localhost Then I configured Internet Explorer on a virutal machine running XP within virtualbox with Brigded network (gets same network address range as regular computers on our network) similar to this Instead of the server name I used the IP address. When I try to access a web page, this doesn't go through and I get the following log messages on the proxy server: Original Client IP Client Agent Authenticated Client Service Referring Server Destination Host Name Transport HTTP Method MIME Type Object Source Source Proxy Destination Proxy Bidirectional Client Host Name Filter Information Network Interface Raw IP Header Raw Payload GMT Log Time Source Port Processing Time Bytes Sent Bytes Received Cache Information Error Information Authentication Server Log Time Client IP Destination IP Destination Port Protocol Action Rule Result Code HTTP Status Code Client Username Source Network Destination Network URL Server Name Log Record Type 10.XXX.YY.174 - TCP - - - 24.08.2010 13:25:24 1080 0 0 0 0x0 0x0 - 24.08.2010 06:25:24 10.XXX.YY.174 10.XXX.YY.175 80 HTTP Initiated Connection MyHTTPAccess 0x0 ERROR_SUCCESS Internal Local Host - PROXYTEST Firewall 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:24 2275 0 0 0 0x0 0x0 - 24.08.2010 06:25:24 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Initiated Connection 0x0 ERROR_SUCCESS Local Host Local Host - PROXYTEST Firewall 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:25 2275 0 0 0 0x0 0x0 - 24.08.2010 06:25:25 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Closed Connection 0x80074e20 FWX_E_GRACEFUL_SHUTDOWN Local Host Local Host - PROXYTEST Firewall 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:25 2276 0 0 0 0x0 0x0 - 24.08.2010 06:25:25 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Initiated Connection 0x0 ERROR_SUCCESS Local Host Local Host - PROXYTEST Firewall 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:26 2276 0 0 0 0x0 0x0 - 24.08.2010 06:25:26 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Closed Connection 0x80074e20 FWX_E_GRACEFUL_SHUTDOWN Local Host Local Host - PROXYTEST Firewall 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:26 2277 0 0 0 0x0 0x0 - 24.08.2010 06:25:26 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Initiated Connection 0x0 ERROR_SUCCESS Local Host Local Host - PROXYTEST Firewall 10.XXX.YY.159 - UDP - - - 24.08.2010 13:25:26 68 0 0 0 0x0 0x0 - 24.08.2010 06:25:26 10.XXX.YY.159 255.255.255.255 67 DHCP (request) Denied Connection [Enterprise] Default rule 0xc004000d FWX_E_POLICY_RULES_DENIED Internal Local Host - PROXYTEST Firewall 10.XXX.YY.166 - UDP - - - 24.08.2010 13:25:26 68 0 0 0 0x0 0x0 - 24.08.2010 06:25:26 10.XXX.YY.166 255.255.255.255 67 DHCP (request) Denied Connection [Enterprise] Default rule 0xc004000d FWX_E_POLICY_RULES_DENIED Internal Local Host - PROXYTEST Firewall 0.0.0.0 Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) Yes Proxy 10.XXX.YY.175 TCP GET Internet - - - Req ID: 096c76ae; Compression: client=No, server=No, compress rate=0% decompress rate=0% - - - 24.08.2010 13:25:27 0 2945 2581 446 0x0 0x40 24.08.2010 06:25:27 10.XXX.YY.174 10.XXX.YY.175 80 http Failed Connection Attempt MyHTTPAccess 10061 anonymous Internal Local Host http://www.vg.no/ PROXYTEST Web Proxy Filter 10.XXX.YY.175 - TCP - - - 24.08.2010 13:25:27 2277 0 0 0 0x0 0x0 - 24.08.2010 06:25:27 10.XXX.YY.175 10.XXX.YY.175 80 HTTP Closed Connection 0x80074e20 FWX_E_GRACEFUL_SHUTDOWN Local Host Local Host - PROXYTEST Firewall

• Windows Azure Virtual Machine Readiness and Capacity Assessment for SQL Server

  - by SQLOS Team

  Windows Azure Virtual Machine Readiness and Capacity Assessment for Windows Server Machine Running SQL Server With the release of MAP Toolkit 8.0 Beta, we have added a new scenario to assess your Windows Azure Virtual Machine Readiness. The MAP 8.0 Beta performs a comprehensive assessment of Windows Servers running SQL Server to determine you level of readiness to migrate an on-premise physical or virtual machine to Windows Azure Virtual Machines. The MAP Toolkit then offers suggested changes to prepare the machines for migration, such as upgrading the operating system or SQL Server. MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys. Now, let’s walk through the MAP Toolkit task for completing the Windows Azure Virtual Machine assessment and capacity planning. The tasks include the following: Perform an inventory View the Windows Azure VM Readiness results and report Collect performance data for determine VM sizing View the Windows Azure Capacity results and report Perform an inventory: 1. To perform an inventory against a single machine or across a complete environment, choose Perform an Inventory to launch the Inventory and Assessment Wizard as shown below: 2. After the Inventory and Assessment Wizard launches, select either the Windows computers or SQL Server scenario to inventory Windows machines. HINT: If you don’t care about completely inventorying a machine, just select the SQL Server scenario. Click Next to Continue. 3. On the Discovery Methods page, select how you want to discover computers and then click Next to continue. Description of Discovery Methods: Use Active Directory Domain Services -- This method allows you to query a domain controller via the Lightweight Directory Access Protocol (LDAP) and select computers in all or specific domains, containers, or OUs. Use this method if all computers and devices are in AD DS. Windows networking protocols --  This method uses the WIN32 LAN Manager application programming interfaces to query the Computer Browser service for computers in workgroups and Windows NT 4.0–based domains. If the computers on the network are not joined to an Active Directory domain, use only the Windows networking protocols option to find computers. System Center Configuration Manager (SCCM) -- This method enables you to inventory computers managed by System Center Configuration Manager (SCCM). You need to provide credentials to the System Center Configuration Manager server in order to inventory the managed computers. When you select this option, the MAP Toolkit will query SCCM for a list of computers and then MAP will connect to these computers. Scan an IP address range -- This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. Note: This option can perform poorly, if many IP addresses aren’t being used within the range. Manually enter computer names and credentials -- Use this method if you want to inventory a small number of specific computers. Import computer names from a files -- Using this method, you can create a text file with a list of computer names that will be inventoried. 4. On the All Computers Credentials page, enter the accounts that have administrator rights to connect to the discovered machines. This does not need to a domain account, but needs to be a local administrator. I have entered my domain account that is an administrator on my local machine. Click Next after one or more accounts have been added. NOTE: The MAP Toolkit primarily uses Windows Management Instrumentation (WMI) to collect hardware, device, and software information from the remote computers. In order for the MAP Toolkit to successfully connect and inventory computers in your environment, you have to configure your machines to inventory through WMI and also allow your firewall to enable remote access through WMI. The MAP Toolkit also requires remote registry access for certain assessments. In addition to enabling WMI, you need accounts with administrative privileges to access desktops and servers in your environment. 5. On the Credentials Order page, select the order in which want the MAP Toolkit to connect to the machine and SQL Server. Generally just accept the defaults and click Next. 6. On the Enter Computers Manually page, click Create to pull up at dialog to enter one or more computer names. 7. On the Summary page confirm your settings and then click Finish. After clicking Finish the inventory process will start, as shown below: Windows Azure Readiness results and report After the inventory progress has completed, you can review the results under the Database scenario. On the tile, you will see the number of Windows Server machine with SQL Server that were analyzed, the number of machines that are ready to move without changes and the number of machines that require further changes. If you click this Azure VM Readiness tile, you will see additional details and can generate the Windows Azure VM Readiness Report. After the report is generated, select View | Saved Reports and Proposals to view the location of the report. Open up WindowsAzureVMReadiness* report in Excel. On the Windows tab, you can see the results of the assessment. This report has a column for the Operating System and SQL Server assessment and provides a recommendation on how to resolve, if there a component is not supported. Collect Performance Data Launch the Performance Wizard to collect performance information for the Windows Server machines that you would like the MAP Toolkit to suggest a Windows Azure VM size for. Windows Azure Capacity results and report After the performance metrics are collected, the Azure VM Capacity title will display the number of Virtual Machine sizes that are suggested for the Windows Server and Linux machines that were analyzed. You can then click on the Azure VM Capacity tile to see the capacity details and generate the Windows Azure VM Capacity Report. Within this report, you can view the performance data that was collected and the Virtual Machine sizes.   MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys.

• ASA 5505 stops local internet when connected to VPN

  - by g18c

  Hi I have a Cisco ASA router running firmware 8.2(5) which hosts an internal LAN on 192.168.30.0/24. I have used the VPN Wizard to setup L2TP access and I can connect in fine from a Windows box and can ping hosts behind the VPN router. However, when connected to the VPN I can no longer ping out to my internet or browse web pages. I would like to be able to access the VPN, and also browse the internet at the same time - I understand this is called split tunneling (have ticked the setting in the wizard but to no effect) and if so how do I do this? Alternatively, if split tunneling is a pain to setup, then making the connected VPN client have internet access from the ASA WAN IP would be OK.

• Feedback on meeting of the Linux User Group of Mauritius

  Once upon a time in a country far far away... Okay, actually it's not that bad but it has been a while since the last meeting of the Linux User Group of Mauritius (LUGM). There have been plans in the past but it never really happened. Finally, Selven took the opportunity and organised a new meetup with low administrative overhead, proper scheduling on alternative dates and a small attendee's survey on the preferred option. All the pre-work was nicely executed. First, I wasn't sure whether it would be possible to attend. Luckily I got some additional information, like children should come, too, and I was sold to this community gathering. According to other long-term members of the LUGM it was the first time 'ever' that a gathering was organised outside of Quatre Bornes, and I have to admit it was great! LUGM - user group meeting on the 15.06.2013 in L'Escalier Quick overview of Linux & the LUGM With a little bit of delay the LUGM meeting officially started with a quick overview and introduction to Linux presented by Avinash. During the session he told the audience that there had been quite some activity over the island some years ago but unfortunately it had been quiet during recent times. Of course, we also spoke about the acknowledged world dominance of Linux - thanks to Android - and the interesting possibilities for countries like Mauritius. It is known that a couple of public institutions have there back-end infrastructure running on Red Hat Linux systems but the presence on the desktop is still very low. Users are simply hanging on to Windows XP and older versions of Microsoft Office. Following the introduction of the LUGM Ajay joined into the session and it quickly changed into a panel discussion with lots of interesting questions and answers, sharing of first-hand experience either on the job or in private use of Linux, and a couple of ideas about how the LUGM could promote Linux a bit more in Mauritius. It was great to get an insight into other attendee's opinion and activities. Especially taking into consideration that I'm already using Linux since around 1996/97. Frankly speaking, I bought a SuSE 4.x distribution back in those days because I couldn't achieve certain tasks on Windows NT 4.0 without spending a fortune. OpenELEC Mediacenter Next, Selven gave us decent introduction on OpenELEC: Open Embedded Linux Entertainment Center (OpenELEC) is a small Linux distribution built from scratch as a platform to turn your computer into an XBMC media center. OpenELEC is designed to make your system boot fast, and the install is so easy that anyone can turn a blank PC into a media machine in less than 15 minutes. I didn't know about it until this presentation. In the past, I was mainly attached to Video Disk Recorder (VDR) as it allows the use of satellite receiver cards very easily. Hm, somehow I'm still missing my precious HTPC that I had to leave back in Germany years ago. It was great piece of hardware and software; self-built PC in a standard HiFi-sized (43cm) black desktop casing with 2 full-featured Hauppauge DVB-s cards, an old-fashioned Voodoo graphics card, WiFi card, Pioneer slot-in DVD drive, and fully remote controlled via infra-red thanks to Debian, VDR and LIRC. With EP Guide, scheduled recordings and general multimedia centre it offered all the necessary comfort in the living room, besides a Nintendo game console; actually a GameCube at that time... But I have to admit that putting OpenELEC on a Raspberry Pi would be a cool DIY project in the near future. LUGM - our next generation of linux users (15.06.2013) Project Evil Genius (PEG) Don't be scared of the paragraph header. Ish gave us a cool explanation why he named it PEG - Project Evil Genius; it's because of the time of the day when he was scripting down his ideas to be able to build, package and provide software applications to various Linux distributions. The main influence came from openSuSE but the platform didn't cater for his needs and ideas, so he started to work out something on his own. During his passionate session he also talked about the amazing experience he had due to other Linux users from all over the world. During the next couple of days Ish promised to put his script to GitHub... Looking forward to that. Check out Ish's personal blog over at hacklog.in. Highly recommended to read. Why India? Simply because the registration fees per year for an Indian domain are approximately 20 times less than for a Mauritian domain (.mu). Exploring the beach of L'Escalier af the meeting 'After-party' at the beach of L'Escalier Puh, after such interesting sessions, ideas around Linux and good conversation during the breaks and over lunch it was time for a little break-out. Selven suggested that we all should head down to the beach of L'Escalier and get some impressions of nature down here in the south of the island. Talking about 'beach' ;-) - absolutely not comparable to the white-sanded ones here in Flic en Flac... There are no lagoons down at the south coast of Mauriitus, and watching the breaking waves is a different experience and joy after all. Unfortunately, I was a little bit worried about the thoughtless littering at such a remote location. You have to drive on natural paths through the sugar cane fields and I was really shocked by the amount of rubbish lying around almost everywhere. Sad, really sad and it concurs with Yasir's recent article on the same topic. Resumé & outlook It was a great event. I met with new people, had some good conversations, and even my children enjoyed themselves the whole day. The location was well-chosen, enough space for each and everyone, parking spaces and even a playground for the children. Also, a big "Thank You" to Selven and his helpers for the organisation and preparation of lunch. I'm kind of sure that this was an exceptional meeting of LUGM and I'm really looking forward to the next gathering of Linux geeks. Hopefully, soon. All images are courtesy of Avinash Meetoo.

• Duplicate GET request from multiple IPs - can anyone explain this?

  - by dwq

  We've seen a pattern in our webserver access logs which we're having problem explaining. A GET request appears in the access log which is a legitimate, but private, url as part of normal e-commerce website use (by private, we mean there is a unique key in a url form variable generated specifically for that customer session). Then a few seconds later we get hit with an identical request maybe 10-15 times within the space of a second. The duplicate requests are all from different IP addresses. The UserAgent for the duplicates are all the same (but different from the original request). The reverse DNS lookup on the IPs for all the duplicates requests resolve to the same large hosting company. Can anyone think of a scenario what would explain this? EDIT 1 Here's an example that's probably anonymised beyond being any actual use, but it might give an idea of the sort of pattern we're seeing (it's from a search query as they sometimes get duplicated too): xx.xx.xx.xx - - [21/Jun/2013:21:42:57 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "http://www.ourdomain.com/index.html" "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)" xx.xx.xx.xx - - [21/Jun/2013:21:43:03 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:03 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" UPDATE 2 Sometimes it is part of a checkout flow that's duplicated to I'd think twitter is unlikely.

• How can I check if PHP was compiled with the UNICODE version of the Win32 API?

  - by Wesley Murch

  This is related to this Stack Overflow post: glob() can't find file names with multibyte characters on Windows? I'm having issues with PHP and files that have multibyte characters on Windows. Here's my test case: print_r(scandir('./uploads/')); print_r(glob('./uploads/*')); Correct Output on remote UNIX server: Array ( [0] => . [1] => .. [2] => filename-äöü.jpg [3] => filename.jpg [4] => test?test.jpg [5] => ??? ?????.jpg [6] => ?????????.jpg [7] => ???.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg [2] => ./uploads/test?test.jpg [3] => ./uploads/??? ?????.jpg [4] => ./uploads/?????????.jpg [5] => ./uploads/???.jpg ) Incorrect Output locally on Windows: Array ( [0] => . [1] => .. [2] => ??? ?????.jpg [3] => ???.jpg [4] => ?????????.jpg [5] => filename-äöü.jpg [6] => filename.jpg [7] => test?test.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg ) Here's a relevant excerpt from the answer I chose to accept (which actually is a quote from an article that was posted online over 2 years ago): From the comments on this article: http://www.rooftopsolutions.nl/blog/filesystem-encoding-and-php The output from your PHP installation on Windows is easy to explain : you installed the wrong version of PHP, and used a version not compiled to use the Unicode version of the Win32 API. For this reason, the filesystem calls used by PHP will use the legacy "ANSI" API and so the C/C++ libraries linked with this version of PHP will first try to convert yout UTF-8-encoded PHP string into the local "ANSI" codepage selected in the running environment (see the CHCP command before starting PHP from a command line window) Your version of Windows is MOST PROBABLY NOT responsible of this weird thing. Actually, this is YOUR version of PHP which is not compiled correctly, and that uses the legacy ANSI version of the Win32 API (for compatibility with the legacy 16-bit versions of Windows 95/98 whose filesystem support in the kernel actually had no direct support for Unicode, but used an internal conversion layer to convert Unicode to the local ANSI codepage before using the actual ANSI version of the API). Recompile PHP using the compiler option to use the UNICODE version of the Win32 API (which should be the default today, and anyway always the default for PHP installed on a server that will NEVER be Windows 95 or Windows 98...) I can't confirm whether this is my problem or not. I used phpinfo() and did not find anything interesting, but I wasn't sure what to look for. I've been using XAMPP for easy installations, so I'm really not sure exactly how it was installed. I'm using Windows 7, 64 bit - so forgive my ignorance, but I'm not even sure if "Win32" is relevant here. How can I check if my current version of PHP was compiled with the configuration mentioned above? PHP Version: 5.3.8 System: Windows NT WES-PC 6.1 build 7601 (Windows 7 Home Premium Edition Service Pack 1) i586 Build Date: Aug 23 2011 11:47:20 Compiler: MSVC9 (Visual C++ 2008) Architecture: x86 Configure Command: cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--disable-isapi" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8-11g=D:\php-sdk\oracle\instantclient11\sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet" "--with-mcrypt=static" "--disable-static-analyze"
