• Tool to automate basic connectivity testing

  - by feicipet

  After our vendors have setup a certain test environment, we need to go in to perform connectivity testing between PC to servers and also between servers. The problem is that we run a range of tests to telnet between 2 nodes on several ports and this is a manual and rather tedious process. Does anyone know of a small tool or script that I can take input on the range of ports to be test and will run an automated range of testing against those ports? All I need to do is to validate whether a TCP connection can be established from the source PC / server to the target server IP address / port. Thanks, Wong

• Can I use multiple email servers at once?

  - by TheLQ

  I was wondering: Can you use multiple email servers at once? In this case, I was going to add all the Google Apps MX records then add the MX records of another email server. My goal here is to only use the somewhat expensive Google Apps for only important email addresses (eg all the employees), then use the other cheap email server for other email addresses like webmaster and some other unimportant but needed emails. My thought is that a mail message would try the first 5 Google Apps mail servers, fail, then go to mine and succeed. Would this work? If not, are there any other options?

• Windows shows incorrect free space on Raid 10 volume

  - by Adenverd

  I have 4 1TB hard drives in RAID 1+0 configuration. Theoretically, I should have ~2TB of available space. Windows says the drive has a total size of 1.81 TB, which I'm fine with. As far as files on the volume go, I used WinDirStat to determine that I have 552.8GB of files on the volume. This means that I should have somewhere around 1.3TB minimum of free space. Yet Windows shows the drive as only having 492GB of free space. Are there hidden files somewhere that I can't see (I have show hidden files/folders turned on)? Does Windows not recognize that old files have been deleted? Is there any way to correct this problem?

• Unexpected "waiting for localhost"?

  - by Tenaar

  So I ran into something that kind of worried me today. Lately my computer has been kind of slow and I'm dealing with that, but today when I opened Facebook in Google Chrome, I noticed a message in the bottom left corner while it was loading the site that said "Waiting for localhost". It was brief and I managed to notice it because my computer is slower than it used to & it caused Chrome to hang briefly, long enough for me to read it. As I'm quite confident in that Facebook isn't running on my localhost, I'm wondering what could potentially make Chrome wait for localhost while I'm loading webpages from external servers. Is there a malware of some kind that I should be worrying about? Unfortunately I have no other information than this to go on, and I have no idea how to further investigate this, if it generated any logs or whatever. I'd appreciate any help in figuring out this matter!

• Powering off sends me to "Launch Windows Repair" automatically instead! What do I do?

  - by Jason

  With Windows 2008 R2 Server, I noticed that if I remotely reboot the machine (because it is hung or I think it is hung), the server, when it restarts, defaults to "Launch Windows Repair" (or something similar) rather than "Start Windows Normally". To change it, I have to trek down to the server room and change the boot up otherwise it will go into an endless loop (because I don't have the setup media and DVD-ROM installed). This seems to be new with 2008 R2 because I have not seen it elsewhere. What do I do? How can I remove this or change the default?

• need help from some professional how to redirect old or invalid url

  - by kath

  I recently upgraded a site and almost all URLs have changed. I have redirected all of them (or so I hope) but it may be possible that some of them have slipped by me. Is there a way to somehow catch all invalid URLs and send the user to a certain page and somehow know what URL the person came from so I could log this, and fix those? I'm thinking I could use .htaccess somehow but am not sure how. I am using PHP Thanks so much! error file is already in .htaccess but seems nothing going to change you can see the error file as below AddHandler application/x-httpd-php5s .php ErrorDocument 404 /content/404.php RewriteEngine on RewriteBase / to see the problem what i want result is i need some thing to redirect if some one types wrong url just check the link even if you delete half of the location at the endof url it still opens http://adsbuz.com/classifieds/abu-dhabi-uae/ it sholud go to the error page but its not giong i neeed some kind force to push it to error page thanks

• How can we recover/restore lost/overwritten data in our MSSQL 2008 table?

  - by TeTe

  I am in serious trouble and I am seeking professional advices here. We are using MSSQL server 2008. We removed primary key, replaced exiting data with new data resulted losing our critical business data in its child tables on MSSQL Server. It was completely human mistake and we didn't have disk failure. 1) The last backup file was a month ago which means it is useless. 2) We created Maintenance Plans to backup our database at 12AM everyday but those files are nohwere to be found 3) A friend of mine said we can recover from Transaction Logs. When I go to TaskRestore Transaction log is dimmed/disabled. 4) I checked ManagementMaintenance Plans. I can't find any restored point there. It seems that our maintenance plan hasn't been working. Is there any third party tool to recover lost/overwritten data from MSSQL table? Thanks a lot.

• How would I Enable FTP on Home PC (Win7)?

  - by jp2code

  In my home, all PCs connect through a small router. Some wired and some wireless. Our Media PC (HTPC) is controlled via a Media Center TV style remote, so managing files on it is tedious. I can access all of the files on the HTPC from my desktop PC, but moving a 6 GB file from \\HTPC\Folder1 to \\HTPC\Folder2 involves copying the data to the desktop and then transferring it back. If I were on the HTPC, this would likely be handled by a simple address change for the file (i.e. it would be done almost instantly). I'm thinking if I could get an FTP program to connect to the HTPC, I could simplify things ...but how do I enable that ability on the HPTC? Then, how would I go about connecting to the HTPC? Would I simply enter \\HTPC as the FTP address?

• Apache logs other user read permissions

  - by user2344668

  We have several developers who maintain the system and I want them to easily read the log files in /var/log/httpd without needing root access. I set the read permission for 'other' users but when I run tail on the log files I get permission denied: [root@ourserver httpd]# chmod -R go+r /var/log/httpd [root@ourserver httpd]# ls -la drwxr--r-- 13 root root 4096 Oct 25 03:31 . drwxr-xr-x. 6 root root 4096 Oct 20 03:24 .. drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite.com drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite2.com -rw-r--r-- 1 root root 0 May 7 03:46 access_log -rw-r--r-- 1 root root 3446 Oct 24 22:05 error_log [me@ourserver ~]$ tail -f /var/log/httpd/oursite.com/error.log tail: cannot open `/var/log/httpd/oursite/error.log' for reading: Permission denied Maybe I'm missing something on how permissions work but I'm not finding any easy answers on it.

• External hard disk not showing up as removable media

  - by mark

  Windows 7 Pro x64, my external hard drive is a Western Digital Carviar Black. The hard drive is connected via USB (tried all my 2.0 and 3.0 ob my Gigabyte GA-X58A-UD7) but once I initialized it in the "disk management" (or whatever the proper term is; I'm using a German edition of Windows) I have to assign it a manual drive letter. Otherwise it doesn't show up. I'm confused because usually externally connected drives (be it USB sticks or real hard disks) just show up as "Removable media", but this one doesn't. Is this OK/expected? Will there be troubles when I go to another Windows computer? I formatted the drive with quick format and NTFS. I changed the permissions to have read/write for "Everyone" on that drive. thanks

• Best Practice for upgrading PHP On Production Systems

  - by Demic

  We Have two load balanced web servers running php 5.3. I've been asked by our dev team to upgrade php to 5.4 because they need certain functionality it will bring. The main issue is that 5.3 is the latest thats been built into the distros repository, so to upgrade using the package manager, Ill need to add another 3rd party repo. I dont have a problem with this per se, but Im concerned about using a package from a "non official" source. The other option is to compile php from source, but I guess this will prevent me from using the package manager to upgrade at any stage in the future? So I guess Im just looking for some guidance on which way to go. Compile from source or install from any old repo that purports to supply php 5.4? Or perhaps theres a third option I havent considered? Thanks in advance Demic

• Windows Server 2003 - Give User Full Admin Privileges

  - by APShredder

  I am running Windows Server 2003. There are a couple of user accounts that I would like to promote to Administrator accounts. I've tried several ways to do so, but I am still relatively new to setting up a server. If anyone has any ideas on how to go about promoting these users, I thank you in advance. EDIT: I should probably mention that this a domain controller. I didn't realize that this changed the answer I was looking for. I apologize, like I said before I am new to the world of servers. EDIT #2: I've added the users to the Administrator group like most of the answer recommended, but the users don't seem to have admin rights yet. I think this might be because they are also in the Domain Users group, which I can't seem to be able to remove them from.

• Horrible time with WAMP, Joomla and Windows 7 (Permissions)

  - by jax

  I have WAMP and Joomla installed on Windows 7. I have made a virtual host outside of the www directory that houses a test joomla site. I have also made a joomla component that I want to install and test on this virtual host. I am having constant problems with permissions. I have given all users full access to the folder containing the files under the security Tab in Win7. It seems to me that when (Apache/PHP) creates a file it put restrictions on the permissions which does not allow it to delete or edit the file anymore so I have to manually go and delete the files when I want to uninstall my component. Also, I cannot install the .zip - instead I have to unzip manually to the tmp folder because when I upload the zip in the Joomla Installer I get the same permissions problems as above. How can I get rid of these issues once an for all?

• Deleting Windows 8 install

  - by Yann4

  I have a windows 7 pc, and I had installed windows 8 on an SSD, so it was the only partition on that SSD. I've now realised that I never use it, so I went to uninstall it and followed these steps. The PC now boots into 7, as expected, however I can't delete or format the drive that has windows 8 on it. The format dropdown selection is greyed out, and I tried to just simply delete all of the files and use the disk as is, but as windows 8 isn't there, I no longer have rights to delete all of the files, apparently. The drive in question has 3 partitions, one that I made for the win8 system, and 2 smaller system-created partitions (one 300MB recovery and 1 100MB EFI) How do I go about formatting the drive?

• How can I get the Android SDK working with Eclipse in Ubuntu 9.10 64-bit?

  - by vulcan99

  I would like to tinker with the Android software development kit, and I have found out that it only support 32-bit versions of the Java Platform and Eclipse. I installed the ia32 Sun Java runtime environment and the 32-bit version of Eclipse. I also used the update-alternatives program to make a java 32-bit preference. Both of these seem to run fine. I also installed the Eclipse android plugins, but my problem lies in the SDK downloaded from Google. When I go to Eclipse preferences and try to tell it about my Android SDK location, there are no SDK targets listed. Has anyone else gotten this running on Ubuntu 9.10 64-bit? Thanks.

• Copy any file with a specific file extension in subfolders into a folder

  - by Onyxius

  I found a script on here that would use 7zip and extract all the files in all the sub-folders of a specific folder and put them in their own folder using the script below. What I need is add to it or maybe use another script if i have to and specify where i want those files to go instead of putting them in their own folder within the folder. I don't know how to do this and hope someone would be able to help. Thanks for the help @echo on FOR /D /r %%F in ("*") DO ( pushd %CD% cd %%F FOR %%X in (*.rar *.zip *.tar) DO ( "C:\Program Files\7-zip\7z.exe" x -o"%%~nX" "%%X" ) popd )

• Share files and catelog them across a server

  - by Ultan

  Hi all, here is what I am looking for, I use a number of software packages when creating online learning courses. I have a huge number of courses and they use text, audio files, images and video files. I am looking for somthing that I can install on our server and upload the content, index, tag and categorise and enter a description so that when a screen print has to be changed for example I can find all the places that I used the image so that I can go in and change the image without having to check every file that I have created over the last year. An open source solution would be great or something that isn't to expensive. Thank you for any suggestions you can make.

• Windows 7 hangs after longer inactivity of user

  - by scooby37

  I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

• Can't connect to web-server on local host behind NAT

  - by eyeinthebrick

  I got Ubuntu as host. I'm running a web-server on http://192.168.199.8:80. It is accessible from the local network, but when I'm trying to reach it by external IP, I go to my router's web-page. I arranged port forwarding on router for port 80 to my local IP 192.168.199.8. Unfortunately web-server is still unavailable via external IP. I checked whether the port is open via http://www.canyouseeme.org/. As it showed that the port is unavailable, I changed port used to 3659 (not forget to rearrange port forwarding rule). Although http://www.canyouseeme.org/ shows that port 3659 is open, I still can't reach my web-server. Where can the problem be?

• Windows Media Player 11 fails to authenticate with proxy (ISA)

  - by Ed Manet

  We have some users who need to use a 3rd party site that embeds Windows Media Player streaming video into a web page. Our users go through an ISA proxy server to connect to the Internet. The browser has no problems accessing the site through the proxy. When Media Player loads, we get prompted for network credentials, but the authentication fails. If we set up Internet Explorer 8 to not use the proxy, Media Player has no problem. Media Player is configured to use the RTSP/TCP and HTTP protocols, but not the RTSP/UDP protocol. Is this necessary? Is there a registry key I can use to enable it? Is this more of a proxy server issue? The proxy guy says it's a desktop issue.

• Hardware advice for bitmap / openGL image processing server?

  - by pdizz

  I am trying to work out a build for a processing server to handle bitmap processing as well as openGL rendering for chroma-keying images and Photoshop automation. My searches here and on Google have turned up surprisingly few results, and seeing that there aren't tags for bitmap or image processing I take it this is a specialized application. The bitmap processing is very cpu-intensive while the chroma-keying and Photoshop stuff is gpu-intensive. I doubt this is a case of over-optimization as our company batches thousands of images a day (currently on individual workstations) and any saving in processing time and workstation down-time would be beneficial. Does anyone have any experience with this type of processing server? Any special considerations that would go into a build like this or am I over-thinking it?

• Ubuntu - Is there a way to associate keyboard shortcuts to bring a window to front?

  - by Bogdan Piloca

  I am using exactly 3 programs: - a browser - a terminal - a code editor I keep all in fullscreen windows. What I need is to be able to bring any one of them up with a simple keyboard shortcut, like Ctrl+Alt+B for browser, etc. Alt-Tab sucks because I have to stop and see where the selector is. Using 3 workspaces is better but still not ideal - I need to think about where I am and where I need to go. E.g. My browser is on top of my terminal and my code editor is to the right of the terminal. So to move from browser to terminal I use Ctrl+Alt+Down, but to move from code editor to terminal I have to do Ctrl+Alt+Left. Instead I should just do Ctrl+Alt+T for terminal, for example. Thanks!

• How to set up server to be accessed from mobile devices [closed]

  - by Kgrover

  I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

• Other options to "balance source" in haproxy

  - by PriceChild

  I have haproxy listening on several ports and pointed at several backend servers. Ideally, I would like it so that repeated communications to the same port get pointed at the same backend. "balance source" isn't workable because often requests come from the same source. Is this doable? I'm also open to non-haproxy solutions. The protocol being used isn't important but is definitely not http. Just assume its ssh and you shouldn't go wrong.

• Effective system to backup this setup?

  - by user71785

  I currently have my development environment on a usb hd. It has things like portable xampp, virtualbox with ubuntu guest, portable firefox and other dev tools. It works fantastic! I can attach it to almost any computer and all works fine. However, if this drive decides to go suicide on me I will be close behind it. The problem I'm having is I use this portable HD almost all the time and so I need a fast way to backup the entire drive. It is around 400gb. Any advice?
