• windows 7 monitor instantly resumes from power off

  - by user167328

  It seems that some service or program is preventing my monitor from going into power save mode but I cannot find a way to dig down the cause. Does anybody know a way to find out which event may be causing the problem? Background information: If I leave/lock my computer I want to immediately power off the monitor. Stupid windows has no program for this so I use a third party utility. I use Display.exe from Noel Danjou since 2005 and have had no problem with it on XP, my Notebook with w7 x64 pro and at the office with w7 x64 enterprise. With my new home pc with w7 x64 pro the monitor goes off but instantly comes back on after a second. So I tested using a power plan with the shortest timeout of 1 minute but with that the display never goes off at all. (Setting a power plan timeout is no useful option because then I cannot read a document or watch a movie without the monitor going off) I could try trial and error methods but this is cumbersome and not what I regard as a professional solution. So I would prefer a way to analyze the windows events to find out the reason for the display staying active. Add On: In the meantime I tried safe mode and also exited from all tray programs but the problem is still there. I also checked the BIOS for special power settings but still no solution (P.S. Mobo is H87-G41 PC Mate with latest BIOS rev.)

• Cisco RV042 VPN with Dynamic IPs - Remote Gateway Not Resolving

  - by Rister

  I have an existing network setup that I inherited from my predecessor. Currently there are two sites, each with a Linksys RV042 VPN router running the 1.3.12.19-tm firmware. They are currently set up with a Gateway to Gateway VPN. One site has a static IP, the other has a Dynamic IP with a hostname set up on no-ip.com. My company is looking to set up another site so I purchased another RV042 only this one was Cisco branded and it is running the latest firmware. I had assumed that I would be able to configure a vpn from our main office (the dynamic ip) to the new site with this router quite easily. However when I set up a new VPN tunnel on either device, it stays on Waiting for Connection and the Remote Gateway shows an ip address of 0.0.0.0 rather than the remote ip address. The other VPN tunnel is still working and I don't see any obvious misconfiguration on the new router. It seems that the router is not resolving the Dynamic DNS address and therefore not giving me the option to connect the VPN. Does a Gateway to Gateway VPN work with Dynamic IP addresses on each end? Are the firmware versions not compatible? Is there something I've missed?

• How can I implement ansible with per-host passwords, securely?

  - by supervacuo

  I would like to use ansible to manage a group of existing servers. I have created an ansible_hosts file, and tested successfully (with the -K option) with commands that only target a single host ansible -i ansible_hosts host1 --sudo -K # + commands ... My problem now is that the user passwords on each host are different, but I can't find a way of handling this in Ansible. Using -K, I am only prompted for a single sudo password up-front, which then seems to be tried for all subsequent hosts without prompting: host1 | ... host2 | FAILED => Incorrect sudo password host3 | FAILED => Incorrect sudo password host4 | FAILED => Incorrect sudo password host5 | FAILED => Incorrect sudo password Research so far: a StackOverflow question with one incorrect answer ("use -K") and one response by the author saying "Found out I needed passwordless sudo" the Ansible docs, which say "Use of passwordless sudo makes things easier to automate, but it’s not required." (emphasis mine) this security StackExchange question which takes it as read that NOPASSWD is required article "Scalable and Understandable Provisioning..." which says: "running sudo may require typing a password, which is a sure way of blocking Ansible forever. A simple fix is to run visudo on the target host, and make sure that the user Ansible will use to login does not have to type a password" article "Basic Ansible Playbooks", which says "Ansible could log into the target server as root and avoid the need for sudo, or let the ansible user have sudo without a password, but the thought of doing either makes my spleen threaten to leap up my gullet and block my windpipe, so I don’t" My thoughts exactly, but then how to extend beyond a single server? ansible issue #1227, "Ansible should ask for sudo password for all users in a playbook", which was closed a year ago by mpdehaan with the comment "Haven't seen much demand for this, I think most people are sudoing from only one user account or using keys most of the time." So... how are people using Ansible in situations like these? Setting NOPASSWD in /etc/sudoers, reusing password across hosts or enabling root SSH login all seem rather drastic reductions in security.

• How to remove Media Center from Windows 8

  - by Arabella

  I bought 2 Windows 8 upgrades, 1 for my PC and 1 for my notebook. I added Windows Media Center to my notebook using the free offer in November (side note: the key was emailed to me within 5 minutes, I see many people have been complaining that it takes a few days). Today I decided to add WMC to my PC as well, so I went onto the Microsoft website, same like last time, and I received the email within a few minutes. Once I added WMC, entered the key and the computer rebooted, my activation is now broken: This product key is already being used on another PC. Try a different key or buy a new one. After rereading the product key email, I realised that the WMC key was exactly the same as the one I had received in November for my notebook (I used the same email, i.e. my Microsoft account Outlook email, for both). I didn't think this would be a problem, as on Microsoft's feature pack page it states: ...is limited to five licenses per customer per promotion. So then I decided, I'll just remove WMC from my PC and go back to Windows 8 Pro. So I turned off the WMC feature, PC restarted, activation still broken because my key has been replaced. I then tried to activate it with my original Pro key. The error it gave was that this key cannot be used with this version of Windows, as it is now Windows 8 Pro with Media Center and not Windows 8 Pro anymore. I've searched a bit and it seems the only way to remove it is do a clean install. I tried the Windows 8 Downgrade Helper, which told me I was already running Win 8 Pro when I tried to downgrade, and that I was running Win 8 Pro with Media center when I tried the other option. To sum up: How do I remove Windows Media Center from Windows 8 Pro without having to do a clean install?

• Bad HD and robocopy

  - by acidzombie24

  After my HD gave me crc errors I wanted to copy one drive to another and picked up a new 1TB hd. I am using the command robocopy G: J: /MIR /COPYALL /ZB First it tried copying the file a few times (i didnt count, its not in my window anymore) and got an access denied error, error 5. Then it tried again and locked up. I tried copying that specific file (14mb) and windows says "cant read from source file or disk". I started robocopy again. Hopefully it will ignore it after a fail attempt or two but what options can i use to say if it doesnt work continue to the next file. It looked like that is what it was doing but for this last one it repeated more then 4times and locked up finally. I'm open to other copy solutions. I do prefer built in solutions. I am using windows 7 Also how might i do this without the /MIR option. Is /S /E good enough? flag reference here -edit- i see i can control retries with /R: but i am still open to alternative solutions.

• PST backup with Volume Shadow Copy Service

  - by NoMadMan

  I was asked to implement the task of backing up 35 PST files ranging from 800Mb to 2000Mb. Windows XP and Windows 2000 workstations are assigned to the users and we have a Windows 2000 domain controller we use to back up files on 3x 500Gb external hard drives. I found several methods from applications to scripts. Local or remote applications would be my last resort. I came across this script based on Volume Shadow Copy Service. CopyWithVss I wanted to know if there would be a problem if the path had spaces. Would mounting the destination path of each PST folder with a drive letter be more practical? My concern with mounting option is that i would eventually run out of letters since I have 35 and possibly more workstations to back up. Lastly, can someone give me an example of CopyWithVss if it were run on a production network? The script is a bit cryptic even after reading several times. Where in the script do I enter the source and the destination? I'm a Mac user so please excuse my ignorance with Windows platform.

• Why is the `remove rows` button not always present in MySQL Workbench?

  - by Shawn

  I'm using MySQL Workbench to remove rows from a table in my database. Most of the time, I will simply write a select statement, then select the rows I want to erase and use the remove rows button (circled in the screenshot below). But sometimes (quite often actually), the remove rows button does not appear. Instead, I get something like the screenshot below: The remove rows button is not there and the remove rows option is grayed out in the context menu, so basically, I can't remove rows... The only way I've found of solving this issue is to run the select query many times until the button appears (it usually does after 3 of 4 times). Does anyone know why this is happening? UPDATE Today, I've been running a select query dozens of times and the button never appears. It seems my incomprehensible workaround no longer works... Help! btw: Using a delete statement does work, though I would rather not have to write one for each row I want to remove as this happens quite frequently during development...

• SBS DC DNS entries going missing?

  - by Chris W

  I've been looking at a problem on a friends SBS (2003) server where the client PC's aren't able to connect to the server with a variety of errors reported. Checking the server itself the only indicator of an issue is an error 5782: Dynamic registration or deregistration of one or more DNS records failed with the following error: No DNS servers configured for the local system. Running a dcdiag reports that there are no DNS records registered for the DC so I fixed the problem by doing a netdiag /fix after which the dcdiag comes back clean and clients are ok again. It happened a few weeks ago as well and the same fix solved it. What are the possible causes of the DC DNS entries going missing? Is this a config option that needs tweaking or could it be solved by something simple like scheduling the SBS server to re-boot periodically? The only change they can think of that was made near to the time of the first instance of this problem occurring is that RRAS was started up to allow for a VPN connection from a home user. NB - The server is setup with a pair of NICs in a team so the server has a single virtual NIC providing both LAN/WAN connections to it. An external hardware firewall is in use rather than the windows firewall.

• Configuring MySQL for Power Failure

  - by Farrukh Arshad

  I have absolutely no experience with databases and MySql. Now the problem is I have an embedded device running a MySQL database with a web based application. The problem is when I shutdown my embedded device it just cut off the power, and I can not have a controlled shutdown. Given this situation how can I configure MySql to prevent it from failures and in case of a failure, I should have maximum support to recover my database. While searching this, I came across InnoDB Engine as well as some configuration options to set like sync_binlog=1 & innodb_flush_log_at_trx_commit=1. I have noticed my default Engine is InnoDB and binary logs are also enabled. What are other configurations to make for best possible failure & recovery support. Updated: I will be using InnoDB engine which supports Transactions. My question is how best I can configure it (InnoDB + MySQL) so that it can provide best possible fail-safe as well as crash recovery mechanism. One configuration option I came across is to enable binary logging which InnoDB uses at the time of recovery. Regards, Farrukh Arshad

• How do I force a restore over an existing database?

  - by Ian Boyd

  I have a database, and i want to force a restore over top of it. I check the option: Overwrite the existing database (WITH REPLACE) But, as expected, SSMS is unable to overwrite the existing database. Of course i don't want different filenames; i want to overwrite the existing database. How do i force a restore over an existing database? And for Google search crawler: File '%s' is claimed by '%s'(4) and '%s"(3). The WITH MOVE clause can be used to relocate one or more files. RESTORE DATABASE is terminating abnormally. (Microsoft SQL Server, Error: 3176) Update The script (before i deleted the database, because i needed to get it done) was: RESTORE DATABASE [HealthCareGovManager] FILE = N'HealthCareGovManager_Data', FILE = N'HealthCareGovManager_Archive', FILE = N'HealthCareGovManager_AuditLog' FROM DISK = N'D:\STAGING\HealthCareGovManager10232013.bak' WITH FILE = 1, MOVE N'HealthCareGovManager_Data' TO N'D:\CGI Data\HealthCareGovManager.MDF', MOVE N'HealthCareGovManager_Archive' TO N'D:\CGI Data\HealthCareGovManager.ndf', MOVE N'HealthCareGovManager_AuditLog' TO N'D:\CGI Data\HealthCareGovManager.ndf', MOVE N'HealthCareGovManager_Log' TO N'D:\CGI Data\HealthCareGovManager.LDF', NOUNLOAD, REPLACE, STATS = 10 I used the UI to delete the existing database, so that i could use the UI to force an overwrite of the (non)existing database. Hopefully there can be an answer so that the next guy can have an answer. No, nobody was in the context of the database (The error message from other connections is quite different from this error, and i only got to see this error after i killed the other connections).

• Internet Explorer ignoring PHP setcookie() from CentOS server

  - by Hussein Sabbagh

  In the past we used a windows XAMPP server for an internal website. It worked fine but had some intermittent issues and we decided to move to a LAMP server on CentOS. We made the switch today but it turns out Internet Explorer ignores every attempt I make at saving a cookie. There is no underscore in the URL being used... the URL is actually the same as the one the XAMPP server used, where I was able to save cookies without any problems. It really doesn't make any sense to me, all of the code is the same. The only thing to change is the version of PHP and the server OS. The website works on all other browsers except IE. I can't even make a simple setcookie call. On a blank test page I use setcookie("test", "test", time()+36000, "/"); sleep(5); print_r($_COOKIE); and there is nothing there. Our users can't log into the website because of this and I have no idea what the issue is. If anyone can provide any clues or resolutions I would greatly appreciate it. Obviously the easy answer is to not use IE, but that is not an option in this case.

• sort utility on cyrillic text

  - by Anton

  I have to sort some lines of cyrillic characters and I want to use the sort utility (on MAC OS X 10.6). The problem is that result is incorrect. I take the text into clipboard, then run pbpaste | sort This is plaintext data, and I also tried passing a file to the sort command. My source data is ??????? ????? ???? ???? ?????? ??????? ???????? ?????? ? ????? ??????????????? ?????????? ???? ?????? And after sorting I get ???? ???? ???? ????? ?????? ?????? ?????? ? ????? ??????????????? ??????? ??????? ???????? ?????????? Theese lines aren’t even grouped by first letter. I tried option -d, but then I get an error sort: string comparison failed: Illegal byte sequence sort: Set LC_ALL='C' to work around the problem. sort: The strings compared were \320\321\321\321' and\320\320\320\321\321\320’. Exporting the variable as recommended doesn’t solve the problem. What can I do to use the sort utility for such a task? Any additional info is necessary?

• Print over remote CUPS server, but just show a subset of the printers.

  - by jdm

  I'd like to print from my Ubuntu laptop (karmic) to some networked printers. Our organisation uses a CUPS server with several hundred printers. What I know I can do is: CUPS_SERVER=printers.company.com acroread document.pdf and then Adobe Reader shows me all available printers to select from. However, it takes a couple of minutes to display the large list, which is really annoying. (The desktop PCs here suffer from this, too.) The other option is to add a new printer with an address like ipp://printers.company.com/printer/bldg1_hp8150 (to the Ubuntu printer configuration = local CUPS server). However, it asks me for a driver. I don't want to / can't always specify a driver, since some printers don't appear in the list. I'd like to let the remote CUPS server handle the driver part (like it does when i set CUPS_SERVER), and do no more preprocessing/"driver stuff" on my side. The ideal thing would be if I could somehow add the remote printer list to my local cups server, and apply a filter, so that it would just display printers a la bldg1_*. This feature was available in KDE3.?, but I can't find something similar in Ubuntu/Gnome. Any suggestions?

• Is it okay to use an administrator account for everyday use if UAC is on?

  - by Valentin Radu

  Since I switched to Windows 7 about 3 years ago, and now using Windows 8.1, I have become familiar with the concept of User Account Control and used my PC the following way: a standard account which I use for every day work and the built-in Administrator account activated and used only to elevate processes when they request so, or to ”Run as administrator” applications when I need to. However, recently after reading more about User Account Control, I started wondering if my way of working is good? Or should I use an administrator account for every day work, since an administrator account is not elevated until requested by apps, or until I request so via the ”Run as administrator” option? I am asking this because I read somewhere that the built-in Administrator account is a true administrator, by which I mean UAC doesn't pop up when logged in within it, and I am scared of not having problems when potential malicious software come into scene. I have to mention that I do not use it on a daily basis, just when I need to elevate some apps. I barely log in into it 10 times a year... So, how's better? Thanks for your answers! And Happy New Year, of course! P.S. I asked this a year ago (:P) and I think I should reiterate it: is an administrator account as safe these days as a standard account coupled with the built-in Administrator account when needed?

• How to implement a virtual server running Ubuntu inside a fileserver in windows?

  - by user541445

  I work in a company that has some limitations regarding their budget. They need client/server aplication. I can code the aplication, I've made mini tests on primordial applications that work. The thing is that they only have fileservers, and the application they need must be concurrent compliant, so the database must be in their local network (Fileserver is the only choice). So far, I have explored almost any option available, starting with: Desktop databases. Access (We have a license)(But concurreny is just not effective, besides it's a windows software, yuck). Sqlite (Nice, but since the information they manage is a lot, I've performed some concurrency tests with INSERTs and doing SELECTS at the same time). It fails, somehow it just stops inserting. Open office Base (I dismember a base office only to see that it was a file mode HSQLDB). I've tried, not concurrent at all. Etc (You name the Open source Desktop Database manager, and yes, I've tried that one.) Server databases Call me a stubborn person, but reading some server databases documentation say that their databases will work in a file mode. I've tried a lot of products. Postgres, MySQL, FireBird, H2, Derby, Oracle Express, IBM DB2 Express, etc. So, I really need a hand here, I've been doing this install/delete/depression thing with a lot of databases for 3 weeks, until I got with a crazy idea and I just came here to express it. So, my question comes down to this: Installing a light virtual OS software like Virtual PC and then installing in there a Server OS like an Ubuntu server inside that virtual software will work? Will it work 24/7 or when I close the virtual pc software? Will this work in a fileserver? Any suggestion, answer, critic to the place I work, crazy new concurrent database that will work in fileserver will be most than welcome.

• Windows XP hanging on login screen

  - by Nathan W

  I have been given two Eee PC 100HA to manage for some people, they are both running the same hardware and XP home but one is having some strange problems with logging on. The main problem is that it hangs at the login screen for ages and sometimes never gets to the desktop. The strange thing is it only seems to do it after the computer has been cold started, but it won't do it if the computer has been restarted. I have made two logs of the start up with process monitor but every time the logger is attached the computer will log in fine. I have also set the computer to blue screen and create a crash dump when you press ctrl scroll twice but when I do it at the hung login it just sits at a black screen and I don't get a crash dump, I have turned off the auto system restart on failure option also. I can usually fix most computer start up and shutdown problems but this one has got me stuffed. Has anyone had the same problems before, or can recommend something that I can try? Cheers.

• Installing Debian 7.1 on FakeRAID/Intel Z77 results in boot with no grub menu

  - by user198982

  I'm trying to install Debian 7.1 from DVD onto 2x500GB drives which are set up in a FakeRAID mirror using the on-board FakeRAID provided by the Z77 chipset. I have followed the guide here https://wiki.debian.org/DebianInstaller/SataRaid. Namely, I booted into the expert install with the 'dmraid=true' option added, installed onto the RAID mirror which the installer correctly detected, then installed grub2 onto /dev/mapper/.. raid volume. I chose to use LVM (so a boot partition + LVM volume). As per the guide, I have uncommented the "GRUB_DISABLE_LINUX_UUID=true" line in "/etc/default/grub" and ran "update-grub" then "grub-install /dev/mapper/.." (with the right RAID device in the command). However, after I rebooted the system, all I got was a grub console. It did not load the menu. I checked and it seems that it never even generated a menu file. I re-installed Debian a few times since, trying out different options and also a few workarounds people posted online, but to no avail. The best I am getting is a grub console. No menu. Some times it will generate the grub.cfg, some times it won't, depending on the workaround I try. I was wondering if anyone else has experienced this issue. There is no need to preach how I should not use FakeRAID. I have seen others trying to figure this out so I think a resolution to this issue would be of interest to more than just me. Also, I first installed the system onto a small drive for testing something else. I made a backup with Acronis and was able to restore that onto the RAID mirror by using Universal Restore. When I installed it onto a 500GB without RAID, backed up using the same method, then restored onto a RAID volume of the same size, it would not boot and I got grub errors. Weird. I can post more details, just let me know what you want to see.

• How to setup the Mac OS X Terminal so it's *just peachy*?

  - by kch

  Hi all, My Terminal is awesome, has every detail just right (for me anyway), and now I'm setting up a few new macs around here and I have no idea whatsoever how to get their terminals to a pretty state. My user account is rather old, has been migrated over many OS X releases and machines, so my Terminal setup has grown rather organically over the years. What I need is a recipe to start from scratch, so 1) I know what I've done, and 2) I can reproduce it anywhere. Things I'm looking for: Full UTF8 support. Setting LC_*, displaying characters correctly, accepting input… I hear this got much easier in 10.5, maybe it all works out of the box now? Setup of OS X-style keyboard text navigation (option-arrows, etc) How you particularly handle meta-key support? (other than ESC'ing your way around) Other things to help our n00bs get around in the shell, such as: List of useful default key bindings (^A, ^D, etc…) Mac-specific .profile, .inputrc goodness Mac-specific tools such as pbpaste & pbcopy, Open Terminal Here, etc If at all possible, a list of files to copy over to another machine that encompasses all the changes made to tune the Terminal. (dotrc files, plists, etc) And, well, anything else really. Just keep the scope on the Mac OS X Terminal application, rather than general unix setup and tools. I think a collection of incomplete answers would be a good start. Post one or two things you remember having done, we'll vote them up, and after a few days I'll try to compile it all into a summary answer.

• Looking for an application that scrolls or pans netbook screens running Windows

  - by therobyouknow

  I'm looking for a Windows 7 and XP compatible Windows desktop panning/scrolling tool. This is to solve a problem where some applications for example MSN have settings/preference Windows that are not resizeable. I have a Netbook with a small maximum screen resolution e.g. 1024x600. The fixed non-resizeable windows are too large for this display screen size so I cannot see all of the items on these windows, particularly the OK button to save settings. What I would like is a desktop scrolling/panning tool where if I move my mouse pointer to any edge of the display, it pans to show the region of the too-large-fixed window that I could not see. I use a Samsung N110 and Toshiba NB100 netbooks. I'm looking for: A general program that provides desktop panning/scrolling/expanded resolution to allow all regions of a non-resizeable fixed window Preferably a non-graphics hardware specific program but will accept a solution that works with both the above machines I'm NOT looking for (i.e. unsatisfactory answers others have asked that I've already searched and found): Advice on what programs to use that DON'T have the problem of fixed windows Alternative operating system solutions Plugging in an external monitor with larger resolution - I use this option but I need a solution when one is not available, e.g. while travelling etc Advice about not using small screen netbooks - I enjoy the compact convenience of them Advice about change the dpi settings in the Control Panel Display settings Advice about guesswork with the tab key to move the focus the off-screen item I cannot see Thank you in advance.

• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• Windows Search not searching in files

  - by Cylindric

  I am trying to get Windows Search to work on my Windows Server 2008 SP2 fileserver, so I can search in files for content. I have added the Windows Search Service role to the server, and using the right-click properties in Explorer set some folders to "Index this location". The problem is that neither on the server or remotely can I search in the files. I seem to get some inconsistencies in the GUIs, for example the "Indexing Options" panel shows me just 6 locations indexed, but if I click "Modify" I see nearly everything ticked. For example, the "SeachTest" folder under "infrastructure" has the "index this location" option ticked, but the "Projects" folder does not. I assume this is why some are grey and some not, but they are all ticked. T The "SearchTest" folder contains some files that have nothing but the text PurpleOrange in it, so I should be able to find those. So, to summarise: Which locations are indexed? The ones in the "Index these locations" list, the ones ticked, or the ones not greyed-out in the list? How do I get to the state where I can click in the search box and type PurpleOrange and see the files?

• Recover data from quick formatted DVD-R

  I need to recover data from quick-formatted DVD-R. Please advise a free of charge option (cheap commercial tools will be ok either). Disk was partially recorded with Windows built in disk recorder and recording most likely was not complete. Afterwards I have inserted partially recorded DVD again and on Windows recorder's message box 'How to use this disk?' selected - 'use for CD/DVD player' and data was completely lost - as new recording session was started. Files of photos were recorded on disk. What I have tried so far: DiskInternals CD-DVD recovery - sees 5 jpg files but can't show preview. Tool is commercial - trial version does not allow to recover files. CDCheck - doesn't see any files and reports errors at attempt to scand DVD CD Recovery Toolbox Free - does not even recognize DVD drive ISO Buster - recognizes two files - one MP3 file for 99% of recorded size and one ARC file for about 100 KB MiniTool Power Data Recovery - Free Edition - does not see any files on DVD Stellar Phoenix CD DVD Data Recovery - does not see any files BinaryBiz Virtual Lab - sees DVD disk but needs license to browse content Please advise how is it possible to recover files from DVD.

• Blocking of certain file downloads

  - by Philip Fourie

  I have a problem where I cannot completely download a certain file from a server. The file is 1.9MB in size but only 68% is downloaded and then it hangs. I tried and these cases, which failed: Downloaded the file with HTTP Downloaded the file with FTP Moved the file to different FTP and web servers behind the ISA firewall Tried with IIS 6.0 & IIS 7.0 Multiple download clients. Which included FireFox, FileZilla (on Windows) and wget (on Linux) This worked: Downloading other files from the same location on the server. Both bigger and smaller and in size than the original. FTP and HTTP worked. Earlier version of this file (.DLL) works. It is as if the content of this file has an influence on this file being served. Network architecture: Client Machine - Internet (ISP) - ISA Server - IIS 7.0 The only constants are the ISP, Cisco router and the ISA server. Is it possible that something is rejecting the download because of the contents of the file? I am hoping ISA is the culprit... I am not a ISA expert is there somewhere I can look to establish if it is indeed ISA causing this? Update: Splitting the file into two parts with a hex editor results in one half of the file being served correctly and the other part not. Zipping the file results in the file being downloaded successfully. However this is not an option for this particular scenario. Renaming the file and its extension also doesn't work. Update 2009/10/22: It does NOT seems to be ISA that is causing this problem. We connected a laptop (running IIS) on an available public IP and still the file download to 68% before it hanged. The two remaining components are the ISP and the Cisco 800 series router. Anyone knows about an issue on the router perhaps?

• KVM Guest Reboot Loop

  - by javano

  I have been pulled into a situation where a KVM server (CentOS 6.2) lost power and upon reboot one of the guests hasn't started up again (XP SP3). I have SSH'ed in and someone must have changed something relating to the hyper visors prior to the power loss, but not rebooted all the guests. This particular guest wouldn't start because it was configured to use /usr/bin/qemu-system-x86_64 which isn't there now (assuming it was before?). I changed it to use /usr/libexec/qemu-kvm as this is what all the other guests on this server seem to be using, and its booting up. Using virt-manager on my local machine I can connect to the display of the XP machine and it gets as far as this screen; http://support.gateway.com/emachines/issues/2-1131285152-01.gif The problem I face now, is that which ever option I choose the machine just reboots. So it's and endless loop. I thought that perhaps a file system error maybe present due to the unclean shutdown. There is an XP SP3 ISO mounted under the guest, which I booted from in an attempt to access the recovery tools, but I don't have the Administrator password! I am out of ideas, and it's turning out to be quite the conundrum. Should I use a 3rd party live CD to test the FS for errors? How else can I trouble shoot these restarts?

• choosing hosting for custom ecommerce site, shared, dedicated, what to look for?

  - by spirytus

  Hi, I have (almost) developed website for my client and now need to decide on hosting. Most of the users of the site will be located in Australia, and so am I and my client. Now, I want to consider everything before deciding on host and few questions comes to my mind: I cannot afford website being down, and all hosts say something like "99% uptime guranted". Should just that be enough or shall I ask hosts for some stats maybe? Does it make any difference if servers and whole hosting company is located in Australia or outside? I've been hosting few sites with JustHost.com on shared hosting (cheapest plan, servers in US I believe) and never seen any delays but could that be an issue? I would prefer Australian company so I can actually go to them and give them piece of my mind if something goes wrong, but US servers seem cheaper. Would share hosting do? Its ecommerce custom build php application, I know there are security issues with sessions etc on shared hosting. Will take precautions of course but could share hosting be an issue? Would dedicated be worthy option considering that my knowledge of server is very limited? I need to run php/mysql, with preferably unlimited bandwidth as with my experience I cannot tell what amount of traffic would be sufficient. Please let me know if I didn't provide you with enough information so you could answer my questions, will gladly explain further. In advance thanks for any answers :)
