• How to invoke a command using specific proxy server?

  - by Xiè Jìléi

  Some applications support proxy (http proxy or socks proxy), and some are not. For browsers, I can specify proxy server in the preferences/options dialog, and other applications may be able to configure proxy servers in config files. For general purpose, can I invoke a command using a specific proxy? Like following: $ proxy-exec --type sock5 --server 1.2.3.4:8000 -- wget/ftp ... I'm using Ubuntu Maverick. P.S. In win32, it can be implemented by hijacking the socket dlls, maybe, I'm not familiar with Linux programming, but I guess it's possible in Linux. though.

• How to load previous kernel via ssh?

  - by Aamir

  I work remotely on my work computer. I am also the root of the workstation that I am sharing with my colleague. Yesterday, I upgraded the kernel to 2.6.31-17 when asked by the update manager but refrained from restarting because I knew my NVIDIA and several other kernel modules wouldn't work. Unfortunately my colleague who is a linux noob restarted the machine and here I am :( I am thinking of changing the symlinks /initrd.img and /vmlinuz to the previous kernel image and use kexec. Please tell some better way to load the 2.6.31-16 release of kernel from ssh and not the grub boot menu. I am using Ubuntu Karmic.

• Sendmail problem

  - by trobrock

  I am trying to get my server to be able to send email from PHP. Currently it is using send mail, but whenever I try to send mail to a gmail address I get this sort of response: --o54Mqd5s008981.1275691959/ServerName Content-Type: message/delivery-status Reporting-MTA: dns; ServerName Received-From-MTA: DNS; localhost Arrival-Date: Fri, 4 Jun 2010 22:52:38 GMT Final-Recipient: RFC822; [email protected] Action: failed Status: 5.7.1 Remote-MTA: DNS; gmail-smtp-in.l.google.com Diagnostic-Code: SMTP; 550-5.7.1 [xxx.xxx.xxx.xxx] The IP you're using to send mail is not authorized Last-Attempt-Date: Fri, 4 Jun 2010 22:52:39 GMT How can I set this up to relay through a google account that I own? Is sendmail the best thing to use, or should I switch to Postfix or something? This is on an Ubuntu Server 9.10

• Why can't I connect to a wifi network with my laptop, when I can with my phone?

  - by Alex Sf.

  I can connect with my phone and use the browser as usual. On my laptop it won't connect when using windows 7 while in ubuntu it will connect, but with no internet. What is going on here and how can I get internet on my laptop ? [edit] It's a public wifi hotspot. I can connect with no issues at home. My network asapter is: Atheros AR5B97. And my phone is an iPhone 3G. The wizard's of no help since it asks me to check the router, which I can't since it's a public hostspot.

• Remote desktop solution for controlling a remote OS X machine in Linux

  - by synic

  The "server" (the host I'm trying to connect to) is Snow Leopard. The "client" is Ubuntu 10.04. I want something like a remote desktop server running on OS X that I can connect to and control from the Linux machine. Something cheap or free would be best. Something that always runs on the OS X machine so that I never have to attach a monitor or a keyboard. I don't want to use VNC, because, well, VNC sucks over this network. Any ideas?

• having trouble setting up ganglia on three machines

  - by Pieter Breed

  I am running ubuntu 11.10 I have one machine with gmetad, gmond and ganglia-webinterface. When I browse the web interface this machine picks up the local gmond output. I then added another machine, running only gmond. I didn't really change anything in the config, only the name of the cluster. This machine's output showed up in the web view. The I tried to add a third machine, similarly to the second, but it's not showing up in the web view. I tried looking at syslog and running as a daemon, but I'm not seeing anything suspicious there. Any tips for trouble shooting this?

• Disable/configure Back and Forward through mouse wheel in Internet Explorer

  - by Subtwo

  I have a problem with Internet Explorer (version 7 on Windows XP). Sometimes (not always) when you use the mouse wheel to scroll a page up/down it instead chooses to go back or forth in the web browsing history. This behavior is the same as when you hold the shift-key simultaneously using the wheel. My guess is that Internet Explorer somehow gets misled by something and thinks that I'm actually pressing shift. This is in turn maybe an artifact of the fact that this particular session is a remote-desktop session originating from Linux (Ubuntu). Needless to say the problem can be quite irritating and the alternative of completely turning off the wheel functionality doesn't seem like an option as other applications would suffer greatly from this. Anyway back to my question(s): Is it possible to map the shift+wheel to a simple wheel event for Internet Explorer? Is it possible to disable the shift+wheel event for Internet Explorer? Any suggestions are greatly appreciated.

• Blank screen after grub menu

  - by Tim

  I just rebooted an Ubuntu Server 10.04. After choosing boot options in the grub menu, though, it just displays a black screen with the blinking white underscore in the upper-left corner. The machine has had (hardware) trouble with networking before, but the problem remains after 10 minutes, so I don't think it's the problem now. Booting into recovery mode or using earlier kernels yields the same problem. This also happens if I boot from another hard-drive. I haven't yet tried to boot from CD as the machine lacks a CD reader. How should I diagnose the problem? Update: My boot options are: recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 567[redacted] linux /boot/vmlinuz-2.6.32-29-generic root=UUID=567[redacted] ro quiet splash initrd /boot/initrd.img-2.6.32-29-generic Update: Also, I cannot access the virtual terminals (ctrl+alt+Fn).

• Why does VNC eat certain characters?

  - by TK Kocheran

  I often use VNC to connect to my desktop upstairs using a laptop downstairs over my home network. I tunnel the VNC connection via SSH. The problem I keep running into is that I'll attempt to type a ! or a : or even a captial A and it will come across the wire as a 1, ;, or a respectively. Is this something I can fix? It's really REALLY annoying while one is programming to have to pop open character map and find a colon and copy/paste it in each time. Running Ubuntu 10.04 upstairs, Linux Mint 10 downstairs.

• VSFTPD: Cannot figure this thing out...

  - by A Wizard Did It

  Alright, I've been giving this the best that I can, reading through various tutorials on google, but I cannot seem to get vsftpd running the way I want. For a short while I had it working with one account, but then that stopped and I haven't been able to get it to work since. I've since reformated and reinstall Ubuntu 10.04 LTS. I used apt-get install vsftpd and that's where I am now... I'd really appreciate if anyone could help me understand exactly how this is supposed to work... How do I add FTP accounts and set their home directory to something like /var/www/public_html?

• Own website fails to load first time

  - by AmazingDreams

  I have a website running on a VPS, every time I first try to load the website the connection times out. If I press try again, it loads directly. I'm not sure whether this is a DNS issue or a server issue. As far as I know everything is set up correctly. Also, it has been doing this from the moment I got this server and set up my domain name. And that's about two to three months ago. You may take a look here: http://www.wegotcha.nl/ As you can see at this moment it's just an image, there are no scripts running in the background or anything. The only error Apache gives me is that favicon.ico cannot be found. It's an Apache webserver running on Ubuntu 12.04.1 (newest version) I update all packages almost every day (apt-get update && apt-get upgrade). I am merely an amateur on the area of webservers so any help will be appreciated. :)

• Standalone server setup for compute capacity

  - by mikera

  I'm developing an application for my company that will require a lot of compute capacity (running some very big mathematical calculations), and looking for some form of server setup to do this. For various reasons, we want to run this on-site in our office rather than hosting it externally. It's been a while since I last had to set up my own servers so I thought I would tap into the collective wisdom of serverfault! My broad requirements are: Budget $30-50k, with an aim to get as much compute capacity as possible for that budget 64-bit servers suitable to run Ubuntu Linux + Java Some relatively standalone rack that can be installed in secure office space Fast/low latency network connections between the servers, but don't really care about connectivity to the outside world Storage capacity shared between the servers - they don't necessarily need their own storage providing they can be booted from a common image Downtime can be tolerated (since the calculations are run in batch mode) The software itself is fault-tolerant, so there is no need for extra resiliency in the server setup (cheap replaceable commodity parts will be fine in general) Given these requirements what kind of setup would you recommend and why?

• how to have files created by CMS have the same ownership as SSH user

  - by Cam

  I am having difficulty on our ubuntu server whereby I have an SSH user that when I create files using this user the ownership is web_user:www-data The problem is when a file is uploaded or created using a content management system like joomla. When files are uploaded through Joomla - such as components / modules... The ownership is set to www-data:www-data This means that I need to then chown all new files to web_user:www-data so we can edit the files. Is there a way to set for a directory and sub-directories that all new files created have the ownership of web_user:www-data? Do I need to use something like setuid or setgid? Any help would be greatly appreciated.

  Hi I'm new to ubuntu and linux so this might be a very begginers question. I have several partitions on my pc and I want to be able to access them with the console.

• apache running but site not accessible

  - by Shyam

  Am pretty new to server administration. So I am not able to get to the root of the problem. I am running Apache2 with mod_php on a 1GB Rackspace Cloud Server (Ubuntu 9.10). My site goes down often, and I have to restart apache2 to get the site working. I checked the "error.log" file. There were no signs of any error messages. I even searched for words like [error] / error / warn / [warn] . But no results. The site goes down and even then apache is running. When the site was down, the checked the status /etc/init.d/apache2 status and it gave ** * Apache is running (pid 433). ** Any suggestions where I should look for the problem. Thanks a lot.

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• Cannot connect to FTP server from external host

  - by h3.

  I have a FTP server (vsftpd) setuped on a Linux box (Ubuntu server). When I try to connect with a computer on the same network everything works fine as expected. But as soon the IP is external it won't connect.. I first assumed the port was blocked, but then: localserver:$ sudo tail -f /var/log/vsftpd.log Wed Jan 13 14:21:17 2010 [pid 2407] CONNECT: Client "xxx.xxx.107.4" remotemachine:$ netcat svn-motion.no-ip.biz 21 220 FTP Server And it hangs there. Do any ports other than 21 need to be open?

• rsync server, uploaded files permissions incorrect

• Storing bundled AMI:s at Amazon EC2

  - by Industrial

  Hi everybody, I am totally new on configuring servers and working with EC2, so please bare with me. I managed after a lot of hair pulling to get a server with Ubuntu up and running with memcached and some other goodies that would make a great package for me. I thought that however, when storing it as an AMI with this tool I would be able to have memcached available next time I launched an instance based upon that image. What can I do to make sure that my configuration is saved properly to an instance? Question number two: - Can I someway make a command that is automatically run on server creation, like initiating memcache with "memcache -d -m 1700 -u root" or even a batch of them?

• Lost Linux root password - Recovery mode and init=/bin/bash fail

  - by Albeit

  I lost/forgot the root password to a server sitting beside me and am trying to reset it. I would rather not have to wipe and re-install or use a Live CD (server is running Ubuntu Server 12.04). What I've tried so far... 1) Boot into "Recovery mode" from Grub2 boot menu then drop into root shell prompt. I am prompted to "Give root password for maintenance". No-go. 2) Change the boot parameters for the main boot option to include "rw" and "init=/bin/bash". When I then boot with Ctrl-X, the screen goes black, and nothing happens (I've waited five minutes). init=/bin/sh and init=/bin/static-sh both do the same thing, while init=/sbin/init boots as normal. Is there anything else I can try to reset the root password? Thank you!

• Server downtime - are these APC warnings the cause?

  - by DisgruntledGoat

  Yesterday I had a problem with my dedicated server (Ubuntu 10.04, LAMP). It wasn't down per se, but running incredibly slowly as if we had a massive overload of visitors (though I don't think we did). It's running smoothly again now. I've been checking through log files etc to see if I can find any issues, the only strange thing is a bunch of these errors, occurring at about the same time as the downtime: [apc-warning] Unable to allocate memory for pool. in [file] on line 49. And a bit later on: [apc-warning] GC cache entry '[file1]' (dev=2056 ino=8988092) was on gc-list for 3601 seconds in [file2] on line 746. Could these errors indicate the cause of the server slowdown, or are they simply a result of the server being slow in the first place? What would be the solution?

• Bootmgr is missing for windows xp

  I know that there are so many posts on this subject but none of them worked for me. I have Ubuntu on my machine and I would like to install windows xp. As my cd/dvd reader does not work, I made a bootable usb from iso image using UNETBOOTIN, but when I try to boot in through USB it says "BOOTMGR is Missing". I have searched a lot but could not find any solution to it. Please note that my hard disk uses ext4 format and my bootable drive uses NTFS. I have set the Boot Sequence as USB Drive in BIOS. Please let me know if you need any additional information to fix this. Thanks
