• direct url to server ip address and port

  - by AM0

  We have a Windows 2012 dedicated server. There’s a custom service running on port xxxxx which accepts connections from our custom built hardware devices over TCP/IP port. As of now we use servername.serverdomain.com:xxxxx to connect to the service and start communication. However, we prefer to use URL instead of server’s name or IP Address. So we got a custom url and set its name servers to point to dedicated server. However, just setting DNS doesn’t seem to be working. Could someone please guide as to how to get it working? UPDATE In short I want www.custom-url.com being forwarded to servername.serverdomain.com:xxxxx. These requests are coming from hardware and not browser.

• Unistalled C++ Redistributables on Windows Vista

  - by VusP

  Windows Vista Service Pack2 32 bit I uninstalled C++ re-distrubutables (was not aware they are necessary for some applications to run) and I am facing error Cannot start application because the side-by-side configuration is not correct when i start applications like Avast, Revo Uninstaller etc. I came across this page. But the downloaded vcredist_86.exe doesn't seem to do much. It extracts itself and that's it nothing after that. No error nothing. I just finished installing 300+ MB updates on my system, so i don't want to use the System Restore option [And, I don't know which Restore Point to revert to]. Any other way to get this done?

• What happened to the ability to go back in a already-loaded YouTube video?

  - by Chelonian

  For many years, my experience with YouTube had been, consistently and on any computer/browser, that once a section of that video were loaded, or the whole video, if you wanted to see an earlier part of the video again, you could simply click on the loading bar to that area and you would instantly go to that part. More recently (6 months?) this has changed. Now, clicking in an earlier part of the video forces a reload of the whole video (that is, the grey bar goes back to 0) and you have to hope your loading will be fast enough to make waiting to watch it again even worth it. It is a huge regression in usability for me. Is there any way to watch YouTube videos in the "old way"? I use Firefox 17.0.1 at this point and have an updated (I think) Flash, but I'd be willing to try other browsers or versions if it made a difference.

• 1 tera flop cluster?

  - by Adobe

  I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: Custer is supposed to run linux, and gromacs in it.

• Phishing attack stuck with jsp loginAction.do page? [closed]

  - by user970533

  I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

• Can I restore closed tabs after quitting Chrome?

  - by Sammy

  I closed Chrome by accident. Now all the tabs I had open are presumably gone. I don't want to risk anything by starting Chrome now before asking for help. I fear that they will be permanently lost (overwritten files) if I do that. I know from past experience with Firefox that restoring tabs and browser sessions can be a tricky business. What can I do at this point? Is there a file or something I need to copy or rename? I know about the Ctrl+Shift+T command. But I normally use this while browsing. Will this work AFTER closing Chrome?

• Excel macro to delete empty rows isn't stopping

  - by RocketGoal

  How do I make it stop after a certain amount of rows? I've taken a VBA course and my teacher explained how to delete empty rows. I'm now trying to put this in place but my macro isn't stopping. I thought I had limited it to 200 rows. I'm missing something important. Any pointers much appreciated. Sub RemoveRows() ' Remove rows from last blank cell Dim LastRow As Long Dim ISEmpty As Long 'Count how many records in the list. This is done so that the Do loop has a finish point. LastRow = Range("A200").End(xlUp).Row 'Start at the top of the list Range("A1").Select 'Loop until the end of the list Do While ActiveCell.Row < LastRow 'Assign number of non empty cells in the row ISEmpty = Application.CountA(ActiveCell.EntireRow) 'If ISEmpty = 0 then delete the row, if not move down a cell into the next row If ISEmpty = 0 Then ActiveCell.EntireRow.Delete Else ActiveCell.Offset(1, 0).Select End If Loop End Sub

• How to get the level and position of the player from an extern program? [on hold]

  - by user3727174

  I want to write a program that needs the current level and position of the player (primary single player). This should work for potentially every game installed and running on the computer my program is running on. The data I need is basically one integer value for the level (if there are any) and three integer values for x, y and optimal z for the position of the player. In which relation/scale or where the null point is does not matter, because this information is going to be interpreted game dependent, I will use this information to read information out of a database created for the game currently running. Currently I'm using C++, but if there is a better option for Java I´m willing to port my program. My thoughs so far are: make a mod for every game that should be supported, get the position/level from there, write this information to the disk and read it from my program tracking mouse/keyboard events and reconstructing the movement won't work Are there any general APIs for something like this? Any Tool to find this data? Or maybe engines that provide APIs to get this data directly from the game?

• Block a Server from reaching a machine

  - by user

  I have a Windows 2003 server that I want to block from accessing a specific IP address. I want to control this from the Server. because I control the machine. The traffic is http traffic (webservice call). It uses a non-standard port, so IP address+ Port combination would also work. Background: I have a development enviornment that for some reason is ignoring host file enteries under some circumstances. These host files point the enviornment at services in another Dev enviornment. Wne th host files are ignored, dev is talking to production. This is not my question, rather the motivation for this inquiry. I want is a failsafe to ensure dev will error instead of happily engaging in transactions with production. I control the dev server, I do not control the firewalls or the target production machine.

• svn:externals cache and stale URLs

  - by dcaunt

  I have a subversion externals entry in a library folder which looks like this: Z https://svn/Z/trunk/library/Z Fetching external item into '/home/releases/50/library/Z' svn: OPTIONS of 'http://svn/repo/trunk/library/Z': could not connect to server (http://svn) The externals URL was the same, but over the HTTP protocol. Having changed the externals to point to the HTTPS, I can't figure out why subversion is still trying to use the old URL. Does subversion cache the externals path, and if so how can I clear this? If not, what else could be causing this? I can check out from the correct (HTTPS) URL fine from the server. NOTE: svn is an entry in the server's local hosts file, pointing to our subversion server's IP.

• mod_rewrite not working after upgrade to 12.10

  - by CrowderSoup

  I'm hoping this is a quick and simple fix and that I just need a fresh set of eyes. However, I'm fearful that it might actually be an error in the latest build of the rewrite module. I have a .htaccess file that turns on the rewrite engine (I've made sure the module is enabled), creates some rewrite conditions, and finally a rewrite rule. Here's my .htaccess file for reference: <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?request=$1 [L,QSA,NC] </IfModule> Now for the problem: if I go to hostname.com it works fine. If I go to hostname.com/Index it works fine. However, if I go to hostname.com/index it doesn't rewrite the request and I get a 404. I'm not sure what's going on here. I've used a rewrite rule tester and there doesn't appear to be any issues with my rewrite rule itself. Again, this issue didn't manifest until after I upgraded to 12.10, at which point I know that Apache was updated. Any thoughts? Has anyone else here experienced this? I know that two other people besides myself have experienced this here. Thanks in advance for any help you can provide!

• Hardware needed for 2000 users? [closed]

  - by Trcx

  I have school assignment that is fairly well defined, requiring us to come up with a plan for an environment serving dynamic web applications to 2000 users, and should be able to scale up to six thousand. I have done plenty of research as far as load balancing, redundancy, UPSs, etc, but am having a hard time figuring out how much hardware is actually needed in the way of physical servers, ram, processing power, etc. The assignment states that the server will have a lot of dynamic code, email, and a database are required, all utilizing the appropriate microsoft service (MS SQL, Exchange, IIS). I already plan on splitting them out on to separate servers, but can't even fathom the hardware requirements of something that large scale. Could someone with experience weight in on this, or point me two some good articles?

• Would you embrace a new technology that worked better than a VPN?

  - by Jumpto

  Ok so VPNs have been around for ages. Business has been addicted to them as the only method of securing their home servers with their workstations in the field. Even with all their problems and shortcomings. So my question is this: How likely are you to embrace a new technology that promises to work better, secure better and have more features than a VPN? State your reasons for or against. Extra points if you point out what steps the new technology would have to take to knock VPN off its throne.

• nginx: handling 404 with error_page

  - by ytw

  Originally, I have something like this in the nginx.conf file. location ^~ /test_api { types { application/json json; } root /usr/local/www/data; rewrite "/test_api/(.*)" /api_response/test_api_$1.json break; error_page 404 /api_response/unknown_request.json; } When a requested resource is not found locally, unknown_request.json (default response) is returned correctly. Then I had to change the rewrite to point to a remote server as follows: rewrite "/test_api/(.*)" $scheme://www.somedomain.com/test_api_$1 break; It doesn't return unknown_request.json (default response) anymore even though the remote server returns a 404. Is there a way to continue to return unknown_request.json to the client when the remote server returns a 404 assuming the remote server can't be changed to return unknown_request.json? Thanks very much.

• Windows 7 user limitation

  - by Eildosa

  I just installed Windows 7 pro x64 from Dreamspark (MSDNAA). But i can't figure out how to configure it. 1/ When I want to acces some folders a pop up show up and tells me "that I need administrator acces to do it" I click the "continue" button and I can go inside the folder. What was even the point in showing me this pop up? how can I remove it? 2/ In some folder when I do a right clic I can only create a new folder, not a new text file, not a rar, nothing. In the same folder I also cannot extract RAR (by doing right clic, extract here) Any Idea how to get back full control? Thanks.

• Unable to debug javascript?

  - by linkme69

  I’m having some problems debugging an encoded javacscript. This script I’m referring to given in this link over here. The encoding here is simple and it works by shifting the unicodes values to whatever Codekey was use during encoding. The code that does the decoding is given here in plain English below:- <script language="javascript"> function dF(s){ var s1=unescape(s.substr(0,s.length-1)); var t=''; for(i=0;i<s1.length;i++)t+=String.fromCharCode(s1.charCodeAt(i)-s.substr(s.length-1,1)); document.write(unescape(t)); } I’m interested in knowing or understanding the values (e.g s1,t). Like for example when the value of i=0 what values would the following attributes / method would hold s1.charCodeAt(i) and s.substr(s.length-1,1) The reason I’m doing this is to understand as to how a CodeKey function really works. I don’t see anything in the code above which tells it to decode on the basis of codekey value. The only thing I can point in the encoding text is the last character which is set to 1 , 2 ,3 or 4 depending upon the codekey selected during encoding process. One can verify using the link I have given above. However, to debug, I’m using firebug addon with the script running as localhost on my wamp server. I’m able to put a breakpoint on the js using firebug but I’m unable to retrieve any of the user defined parameters or functions I mentioned above. I want to know under this context what would be best way to debug this encoded js.

• Updating a modified Prestashop

  - by Emphram Stavanger

  I don't know if this is the proper forum for this; didn't really seem like a Stack Overflow question, so if I'm in the wrong here, do point me to the correct SE site. Anyway, I have a Prestashop 1.4.7.3 installed on a CentOS 5 machine. Recently, they released the 1.5.0 version, which I'd like to upgrade to. However, during developing a rather customized theme for it, I had to modify the core files (and yes I know how stupid this was, and probably even more stupid that I didn't keep a list of modified files). What's done is done though. So now I'm faced with a problem; I need to update, but I don't want it to overwrite my modifications. Is there a way (preferably in the console) to do a diff between my current installation and 1.4.7.3 vanilla, to get a list of files that are modified (sans the themes folder, perhaps)?

• ubuntu 10.04 span window across workspaces

  - by jakerman999

  I'm using an old server machine as a linux box desktop, and as such I have a lot of power but not a lot of display options. I cannot increase my resolution past 800x600 and recently this has become just to small. I have mostly been able to workaround windows being to large for a workspace by moving them with the alt key, but I would like to use something a little more versatile. My plan is to have a setup where I can open a windows (say firefox) on the top-left workspace and then resize it so that it fills four workspaces in an emulated "wall of monitors" fashion. I already have my workspaces arranged like this, but I am not seeing any options for allowing programs/windows to exist on more than one workspace at a time, I know that what I am trying to accomplish is possible (or was at some point in time) because when I google my solution pages appear with people trying to do the opposite (windows already appear on more than one workspace and they dislike it). Any help is much appreciated.

• How to write more than one line in a launcher

  How can I run three commands in a launcher? My commands are cd /home/seraex/MyDoc rm MyDoc.tgz tar cfz MyDoc.tgz * which will go to my documents folder and delete old backup and make a new backup. At the moment I make a text file and then make a launcher and point it to the file, but I want to delete the file and make the launcher run the commands directly. I'm using ubuntu 10.10 ' ubuntu site says 'Unfortunately launchers do not have access to the Bash environment so you cannot just include the multi commands' when i ggole chaining in launchers. thanks, admin may delete the question '

• The [2] table entry '[3]' has no associated entry in the Media table. (error 2602)

  - by derekf

  Coworker started getting the above message in the event log and as dialog during install.  Argument [2] was File and argument [3] was a specific file. Error dialog read   Product: (app name) -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2602. Package was a vendor-provided MSI that had been installed administratively, and then a patch (.msp) applied to the administrative install point. With some digging we found that the MSI still had the entries in the media table pointing at the CAB files, and that there were several files at the end of the sequence that did not have corresponding entries in the Media table (last sequence 990 in Media table, last entry in File table had sequence 994).  Attributes on files in the File table all had the msidbFileAttributesCompressed (&16384) attribute set, so they were all expecting to be within the CAB files, but since this was an admin install there were no CAB files. Resolved by clearing the Media table (replace with a single entry: Disk ID 1, LastSequence 994) and going through the file table and subtracting 8192 from each entry to mark files as not compressed.  Tested and worked.

• Trouble getting OS fingerprinting to work in iptables

  - by user1197457

  Everyone, As I understand it, OSF has been merged with the Kernel since 2.6.before-my-kernel-version. Yet when I do something like this: iptables -I INPUT -j ACCEPT -p tcp -m osf --genre Linux --log 0 --ttl 2 and I get an error like: iptables: No chain/target/match by that name iptables -L Shows no rules because I did an iptables -F at one point. ALSO, the following command: cat /proc/net/ip_tables_matches Does not show "osf" on the list. A google doesn't seem to help. I've also installed iptables-devel in hopes I'd be able to load the osf module. Sadly I haven't been able to get that to work. Centos 6.4 minimal Any guidance?

• My computer is broken after recent update attempt to 14.04

  - by user317550

  So it all started on a day much like today, because it is today but that's not the point, when I got a notification telling me I haven't upgraded to 14.04. Not due to lack of trying, however. It offered to upgrade me itself. Now keep in mind, I've tried very hard to upgrade my is from 12.04 to 14.04. Many times, I believe, due to tinkering where there shouldn't be tinkering, my BIOS are messed up. So upgrading is essentially impossible, but I wasn't about to stop it from updating for me, thinking it didn't have too much to do with BIOS as it doesn't reboot until after. So I let it go about its business and some time later I look back at it, and my unity sidebar is gone, and anytime there's text on screen it shows as those box things. The real bottom line is that I want to know my options. All of them. I would love to be able to keep the stuff on my hard drive so a hard drive swap may be an option if you guys say that would work. I just need my computer back. Let me know if I left anything out. Peace! B^)

• Growing your VirtualBox Virtual Disk

  - by Fat Bloke

  Don't you just hate it when this happens: Fortunately, if you're running inside VirtualBox, you can resize your virtual disk and magically make your guest have a bigger disk very easily. There are 2 steps to doing this... 1. Resize the virtual disk Use the VBoxManage command line tool to extend the size of the Virtual Disk, specifying the path to the disk and the size in MB: VBoxManage modifyhd <uuid>|<filename> [--type normal|writethrough|immutable|shareable| readonly|multiattach] [--autoreset on|off] [--compact] [--resize <megabytes>|--resizebyte <bytes>]   If you booted up your guest at this point, the extra space is seen as an unformatted area on the disk, like this: So we now need to tell the guest about the extra space available. 2. Extend the guest's partition to use the extra space How you do this step depends on you guest OS type and the tools you have available. Linux guests often include the excellent gparted partition editor, whereas Windows 7 and 8 provide the Computer Management tool which can resize partitions. Unfortunately, my Windows XP vm has no such tool. But I do have a couple of other options: Most Linux installable .isos include the aforementioned gparted tool, so I could simply attach, say, an Ubuntu.iso as a Virtual CD/DVD in my Windows XP vm and boot off that. Then use gparted to extend the Windows XP partition, before finally rebooting. But I took another route and attached my resized virtual disk to a Windows Server 2012 vm I had lying around. Then I used the Computer Management tool in Windows Server 2012 to extend the partition of the Windows XP disk, before shutting down, unplugging the disk and reattaching to my Windows XP vm. (Note that if your vm's use different disk controllers, Windows will check the disks on booting). When I finally boot up my Windows XP guest I see the available disk space and all is well. At least until the next time - FB

• NFS default to 777

  - by ipengineer

  I have an NFS share. This share is shared between several different applications. Our web server is running PHP and when it creates directories it is not setting the permissions correctly so it cannot write to the directory once created. How can I mount this NFS share to where PHP has full read/write access? Below is the directory that has been created along with the media server export options and the mount options on the web server. Ideally I could set the permissions on /opt/mount and whatever group/user is on that directory when I mount to that point the share assumes those permissions. dr----x--t. 2 nobody nobody 4096 Jun 5 2014 user_2 Mount output: media.dc1:/home/fs_share on /opt/mount type nfs (rw,vers=4,addr=10.10.20.127,clientaddr=10.10.20.42) Exports file from media server: /home/fs_share 10.10.20.0/255.255.255.0(rw,sync,no_root_squash)
