• Grub2 menu after crash

  - by poopa

  Hi, I have ubuntu 9.10 desktop VMware VM with the default grub2 installed. There is some weird problem with this VM. When you clone this vm and have a customization script run, the cloned machine crashes at first boot (VMware does not officially suport customizaing Ubuntu newer than 8.04). After the creash the Grub boot menu is displayed but there is not time out. I checked /boot/grub/grub.cfg and it does indeed show a timeout of 10 seconds. Nothing happens till I select an option with the keyboard. The second time the Ubuntu loads, it does not crash. My question is, how do I make the grub menu timeout in that case? Thanks.

• Joining windows LANs through SSH tunnel

  - by Akke

  I have at home a computer (a windows 7 ult machine) I need to use to manage stuff at the office which hosts windows and linux servers. I am able to set up a SSH tunnel (atleast for firefox proxying) and I'd like to be able to access shared windows network drives on the other end too. I heard something about needing some kind of samba service but I couldn't find anything useful by googling that. What do I need in order to make an SSH tunnel to the office (a NAS, running linux) so that I can access windows server 2008 and windows 7 network drives? Bonus: I'd like to be able to access a MSSQL database server too if it's possible.

• How can I retrieve "remembered"(stored) wi-fi password from a win. 7 device?

  - by user180880

  I have access to PC, and I am a standard user. Everything(incl. "show charecters" tickbox at wiriless menu) requires admin access. Now, that said machine is actually like a big tv with touch. Type-stuff is handled by virtual keyboard of windows. I can reach to c:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces and can see-open files there, which is I assume where passwords stored are. Now the problem is that these passwords is encypted. I'm ok with if there is a way with changing/resetting admin password as well. Considering this device has nothing but massive amounts of usb(yep, not even cd-dvd // rw) the only way is from inside or with usb without admin rights.

• Is there a way to import a scheduled task from windows 2003 (.job) to windows 2008 (.xml) ?

  - by Rodrigo

  I had some jobs to be moved from the old production server (windows 2003 server standard) to the new machine (windows 2008 server standard), but the new server is unable to read the old .job format, also the import wizard only imports from .xml job files (same version). Obviously I don't want to rebuild all the jobs by hand, but can't find a tool that makes the process a very little easier. I don't trust in Microsoft for this kind of tools, my previously experiences had been to bad (DTS - SSIS). Any ideas? Thanks in advance.

• remoting to pc's already setup with pocketcloud

  - by KiloJKilo

  I use pocketcloud to remote desktop into my PCs on my home network. I would like to remote desktop with windows on my laptop via windows 7, but I'm not really sure how to, without breaking pocketcloud's connection. Does pocketcloud change my router's port forward to each machine as needed? Is there a way I can piggyback on the pocketcloud app? It appears to use 3389 but nothing is routed on that port in my router. Any ideas on how to accomplish this?

• Forwarding audio like X in SSH

  - by Akilan

  While it is possible to use X applications remotely by using -X switch in ssh, the sound is being played in remote machine's speaker only. For example if I view a film in VLC/Totem only video is visible and I can't hear the audio. Is there a way to forward audio too? [without digging through Pulse-audio's setup, I mean; Like how ssh understands X forwarding by itself.] I have tried this only in Ubuntu (in various Ubuntu versions from 9.10 through 10.10), if that helps.

• Speed up connection to MySQL

  - by Leonick

  So here's one for you. Any idea on a way to shorten the time it takes to connect to a MySQL database? The reason I'm wondering is because I find that just connecting to the DB adds just over a second to the rendering of the page and that seems a bit long considering Apache and MySQL is running on the same machine and the mysqli_connect is connecting to localhost. It's just such a shame when the connection takes a second while any query I end up doing won't add any significant amount of time to the render/load time. Any ways to shorten the time it takes to open a connection?

• Slow Crash with Filter Manager

  - by Alex N.

  I have been having sporadic freezes on my machine lately. There is no blue screen or crash screen. All the applications just stop responding and ~5~10 minutes later it will power off. After checking the event log a couple times, I have found that the same event occurs right before each crash. File System Filter 'Avgmfx64' (6.1, ?2011?-?12?-?23T08:08:12.000000000Z) has successfully loaded and registered with Filter Manager. My question is twofold: I can not seem to find any information on what the Filter Manager actually is supposed to do. for curiosities sake, what is it? And more importantly, how do I fix this problem. From the research I have done, I see that similar problems can be caused by out of date drivers, so I have already taken the time to update all of my drivers, run MemTest, and verify the drive integrity.

• OS won't boot during vs2010 install on vista 64

  - by Noam

  I am installing vs2010 on a vista 64bit machine. During the install it asked for a restart. Since that, vista won't load. I tried restore to previous good config - didn't help. I am only able to boot it using safe mode with networking. When I did that, it continued the vista part of the install (the screen with the 3 out of 3 updates) but after that when I restarted again - still fails. HELP!!!

• How to tell Mercurial to never create hard links

  - by scrapdog

  I am planning to use Mercurial in the near future on some projects. These projects will normally reside in a directory on my Windows machine, but I will be sharing these directories using VirtualBox so I can work on them directly from within Linux. I understand that Mercurial will sometimes create hard links when cloning repositories. I'm not sure how a VirtualBox shared directory handles these hard links (or if it even can), so I'd rather just tell Mercurial to never attempt to make hard links and always make a copy. My question: how do I globally disable Mercurial from hard linking? (Although if someone has gotten Mercurial and VirtualBox shared folders to work nicely with hard linking, I'd like to hear about it!)

• Could 1 GB of RAM work better than 1.25?

  - by user67082

  This is for a server running Ubuntu Server 10.10. The server is an old desktop PC. It had 2 sticks of 256 MB of 182-pin DDR 400 MHz RAM in it (total 512 MB of RAM). I just ordered a 1 GB stick of compatible RAM for the machine (now would have a total of 1.25 GB of RAM). A friend told me that it might run better if I removed both sticks of 256 MB RAM and used just the 1 GB stick I will be receiving. This seems counterintuitive since then there would only be 1 GB of RAM instead of 1.25; is it possible that it would be better to run with 1 GB or is he totally wrong? Thanks for the help.

• 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?

• Exchange 2010: Import a PST when Local Move Request fails

  - by gravyface

  So the trail of tears continues with my SBS 2003 to 2011 migration: all the mailboxes have moved mailbox store from OLDSERVER to NEWSERVER, with the Local Move Requests completing successfully, except for one. I've logged into their machine and have exported their mailbox as a PST. I'm about to import it, but it seems to me that because the mailbox is still on OLDSERVER, even with a new Outlook profile pointing to NEWSERVER in Outlook, it'll push the mail into the current mailbox store on the old server. Please tell me I don't have to blow away her existing mailbox, logon, etc. on the old SBSERVER: is there a way to change the state from "Legacy" to "User Mailbox" without actually moving the mailbox store? Create a new mailbox for her user in NEWSERVER?

• Application running as a service is not able to create the same number of processes as when it runs

  - by Pini Reznik

  I have a Windows application which creates up to 35 processes and it's working OK when it's running from cmd. But when it is executed as a service on the same machine it is able to create only 20 processes and all other are killed because of some kind of resource exhaustion problem. The problem is persistent on one Windows 2003 server but not reproducible on other servers. Can it be because the system has run out of desktop heap? http://support.microsoft.com/kb/184802 How can I check it?

• Redirect outbound traffic on port 53 to port 5300 with iptables

  - by Zagorax

  I'm running a local dns server on port 5300 to develop a software. I need my machine to use that dns but I wasn't able to tell /etc/resolv.conf to check on a different port. I searched a bit on google and I didn't find a solution. I set 127.0.0.1 as nameserver on /etc/resolv.conf. Could you please tell me how can I redirect outbound traffic on port 53 to another port? I tried the following but it didn't work: iptable -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to 127.0.0.1:5300 iptable -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 127.0.0.1:5300

• Crunchbang asks for URIs to get build dependencies for php5 [closed]

  - by Koen027

  I'm trying to install PHP5, by compiling it myself. I'm doing this on Crunchbang Linux, version 11. Specifically, the version using the 3.2 kernel. Crunchbang 11 is based on Debian. This is a 64-bit Virtual machine, running on a 64-bit Win7 Professional. Using Virtualbox 4.2 This is my sources.list file: http://pastebin.com/rQJNwX7c When I try to do sudo apt-get build-dep php5, I get the following output: Reading package lists... Done Building dependency tree Reading state information... Done E: You must put some 'source' URIs in your sources.list I'm not sure what's going on here. Can anyone point out what's missing in my setup? Also, since I'm under 300 reputation on serverfault, I can't add the "crunchbang" tag.

• Java on 256MB system?

  - by Mike S.

  For a school project, I've registered a free VPS on a hosting provider (pipni.cz). It has 256MB RAM: Mem: 262144k total, 148104k used, 114040k free, 0k buffers It's running on Debian Squeeze. I always get this error when I run a Java program: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I tried to use Xms, Xmx, Xss with low values and still same result. ulimit -v gives me "unlimited". My application will be pretty simple and I need to use rmiregistry also. Can somebody help?

• Add/Remove script for local printer

  - by GxFlint

  I have a Windows XP machine that runs two applications and both print on a thermal printer connected by a serial port. For one application, the "Generic / Text Only" printer must be present, for the other to work I need to remove it. I've found a few .vbs scripts, but they are for network printer. How do I make them work with my local printer? Is there a better solution? The user would have to run the script every time he needs to switch from an application to another.

• Restrict whole system on certain cores except a few process?

  - by icando

  Hi I am running some latency sensitive program on a Linux machine (more specifically, CentOS 6), and I don't want the threads of the process being preempted. So in my plan, the first step is to set cpu affinity of the threads so that threads are running on separate cores, so they don't preempt each other. Then the second step is to make sure other processes in the system not running on these cores. So my question is: is it possible to restrict the whole system running on certain cores, except this process? This should apply to any newly created processes in the future.

• How to configure permissions for win2008 task running as Network Service to stop/start a service on different system?

  - by weiji

  Well... title says it all, actually. We've got a Scheduled Task set up on a windows server 2003 box running as the Network Service, and the batch file it runs will invoke "sc" to stop and then start a service on another windows box, however sc reports: [SC] OpenService FAILED 5: Access is denied. Running the same batch file via the windows explorer has no issues, and my user account is part of the Administrators group so I believe this is why there are no issues when I try it manually. Is this a permissions thing I enable for Network Service on the first server? Or do I enable permissions for Network Service somehow on the target server? This question (http://serverfault.com/questions/19382/why-sc-query-fails-from-one-machine-but-works-from-another) touches on something similar, but I'm looking for enabling the Network Service to access the service via the scheduled task.

• Which UPS, for home use, which can automatically shutdown the PC when battery is low?

  - by Tony_Henrich

  I am planning to build a single server machine which is highly dependent on data residing in RAM for performance reasons. I am looking for a UPS which can power the PC during a blackout (very rare) and when the battery level is like %20, it sends a signal to Windows 2008 to shutdown. Even if it's only for a few minutes, that's good enough. This is for home use so I am looking for an inexpensive unit ( less than $300? ). Which brand/model is good choice? I prefer one whose battery is easily & cheaply replaced.

• Install correct libraries depending on 64/32 bit

  - by Rich

  I am using Bash to install a customised version of JBoss, and one of the things I would like to do is install the correct version of the Apache Portable Runtime, which is a native binary. This script could be run on both 32 and 64 bit versions of RHEL. What are my options for identifying which version of the APR to install? I think we only have 32bit and x64-based systems here. I would still like to identify i64 systems so that the script can refuse to install on that type of machine. I am aware of using uname -m and grepping /proc/cpuinfo to find out, but was wondering which approach others would recommend?

• cant access my local web server with the external IP

  - by TommyG

  I havent been able to find a solution to my particular problem. I have a MAC which I set up as a web server and configured my router to forward to the local IP. When trying to access my site from outside, it does say "It works!", however, when I call a simple Hello World PHP script that I have, I am getting an error that the page could not be opened. I did enable PHP on my machine so thats not the problem. I really have no idea how can I access - I followed so many tutorials and did everything correctly. My router is a Linksys WRT160N if it matters at all. In the port forwarding section, I selected to forward

• Are Uninterruptible Power Supply (UPS) at home really a worthwhile investment for home computing? [c

  - by Jian Lin

  Possible Duplicate: Is a UPS a good investment for a home machine? I have 2 Uninterruptible power supplies at home, but they seem to expire after 5 years or so. During this 5 years, it maybe saved the computer from turning off twice. But I wonder, I often save my documents every 10 minutes. So the most I can lose is 10 minute worth of work. Not to mention that, I may not be editing anything when the power is out. Also, when the UPS expires, one of them will give out beeping sound once in a while, probably signaling the changing of the battery. So I can either buy 2 new UPS or just buy 2 power outlets instead. 2 UPS, costing $160 to $250 roughly, can it be really worth it if it can save your computer from powering off for just 2 times? What are the alternatives?
