• Open application in background without losing current window focus. Fedora 17, Gnome 3

  - by Ishan

  I'm running a script in the background which loads an image with feh depending on which application is currently in focus. However, whenever the script opens the image, window focus is lost to feh. I was able to circumvent this by using xdotool to switch back to the application that was originally in focus, but this introduces a short annoying period of time where the focus is switched from feh to the application. My question is this: is there any way to launch feh in the background such that window focus is NOT lost? System: Fedora 17, Gnome 3, Bash Thanks a ton!

• Auto restart server if virtual memory is too low

  - by Sukhjinder Singh

  There are quite number of software running on my server: httpd, varnish, mysql, memcache, java.. Each of them is using a part of the virtual memory and varnish was configured to be allocated 3GB of memory to run. Due to high traffic load which is 100K, our server ran out of memory and oom-killer is invoked. We've to reboot the server. We have 8GB of Virtual Memory and due to some reason we cannot extend to larger memory. My question is - Is there any automated script, which will monitor how much virtual memory left and based upon certain criteria, lets say if 500MB left than restart the server automatically? I do know this is not the proper solution but we have to do it, otherwise we don't know when server will get OOM and by the time we know and restart the server, we lost our visiting users.

• Why are application folders going in usr/share instead of home folder?

  - by person

  For example, when I do something like... sudo apt-get install vim It creates a vim folder in usr/share, even though I expect a .vim folder to be created in the home folder.

• which user is the website host

  - by Kossel

  I m learning about server, and I'm configuring nginx mysql php wordpress. the server distro is debian 6. I created a new user and I wish each user is the owner of the site folder /var/www/site.one so I chown -R kossel:kossel site.one my problem is, my wordpress only work if I chmod 644 wp-config.php, which all can read wordpress site suggest that file should be 640. and my question is: when someone open mydomain.com, wordpress has to access wp-config.php file, but which user is it actually using to "read" that file? root? user kossel? anyone else? how can I properly give it permission or owner??

• How to get a list of Dovecot IMAP users

  - by Colt McCormack

  How do you get a list of users for a dovecot email server that connect via IMAP (as opposed to POP)? Our server is setup to authenticate via LDAP/PAM. Is there an easy way to get a list of the users who are accessing their mail via IMAP, rather than POP? I am about to migrate our server to Google Apps and want to migrate all of the mail for my IMAP users only (couple hundred out of several hundred total users). POP mail will be migrated separately from the client end obviously. I would much rather migrate only the IMAP users rather than the whole domain which would include migrating a bunch of POP mail left in the server that has already been read/sorted/deleted in the client's email program. Migrating all of that extra useless leftover POP mail could waste weeks of migration time. I suppose parsing some logs to see who has connected on an IMAP port (995 or 993) would give me a list would work if someone could help me do that. I know I have the raw dovecot logs, but am hoping for a cleaner solution.

  I'd like to rearrange the content of a file on a per line basis (see below), ideally without using Perl or Python (I'm not allowed to... Don't ask.) The input file contains unordered header lines and lines with backup operation results. The output files should contain the lines ordered as shown below. Original file: Completed Backups Backups with Warnings Failed Backups Server A backup was completed with warnings Server B backup was successful Server C backup failed Server D backup was completed with warnings End result: Completed Backups Server B backup was successful Backups with Warnings Server A backup was completed with warnings Server D backup was completed with warnings Failed Backups Server C backup failed

• Can I use Cygwin as a replacement for Ubuntu, for bash script testing?

  - by Jeroen De Meerleer

  Next wednesday i'm having an exam on Operating Systems. In this exam there will also be a part bash-scripting. The teacher itself will test the scripts in a Virtual Machine running Ubuntu. Myself, however, I'm having serious troubles with running the latest Ubuntu (14.04 LTS) on a Virtual Machine (there are troubles with gnome running very slow). So I'm thinking about using Cygwin, which is doing the job great for another course. The teacher already confirmed I can use that, but I'm thinking he doesn't know it at all. I've already tested the scripts we made in class and they're all running without errors. But I'm quite sure there are some things I have to mind on. My question: would you use Cygwin as a replacement for the Ubuntu VM? Or should I stick it with the VM (maybe by using a different config/platform).

• Migrating a running production server to Xen, unmodified as a second HDD?

  - by DaveCol

  I have a production server which I am looking to virtualize via XEN. For this purpose I have purchased a new Sata HDD, in which I have promptly installed CentOS 5.5 x64 with XEN server installed. Now I have two HDD: /dev/sda1 running as host with Xen Server Installed; and /dev/sda2 which is the HDD where the original server has installed. Is it posible to use /dev/sda2 to work as GuestOS in a xen server? Would I have to modify its kernel? Thank you for any input

• Improving sound quality with remote ESD server

  - by cuu508

  Hi, I'm investigating low-budget ways to get audio from my PC (Ubuntu) to HiFi without wires. I'm currently testing a setup where Asus WL-500gP wireless router runs ESD daemon and has attached USB soundcard which is then plugged into HiFi. I'm testing playback on PC with mpg123-esd and Spotify under Wine. The sound is there, latency is unexpectedly low, but I also hear occassional clicks and some distortion from time to time. I suppose that's because of the low latency and wireless streaming of uncompressed audio--any packet drops, CPU temporarily being busy etc. will cause clicks in sound output. Is there a way around this problem, increasing latency / buffer size somehow perhaps? Streaming using shoutcast protocol seems to be a way out but I have feeling that would be a complex and brittle setup.

• Thunderbird doesn't raise or give focus when you click "Write" or "Reply".

  - by Neil

  I'm using Thunderbird 2.0.22, the version that comes with Ubuntu Intrepid 8.10. When I hit "Reply" or "Write", a new email window pops up, but it ends up being under the main Thunderbird Window, and doesn't have focus. Thunderbird is the only application that exhibits this weird behaviour, and it just started happening one day, whereas it worked fine before. I've seen this problem years ago as well, and wasn't sure how I fixed it.

• Hard Reset USB in Ubuntu 10.04

  - by Cory

  I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: $ sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: $ sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on serverfault as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

• good books about server architecture?

  - by ajsie

  when the traffic for a website grows i dont think one apache server in a vps is the way to go. i would like to know more about how i then should set up the server side architecture. im not that much into hardware stuff (what kind of cables to use, different cpu architectures etc), but interested in the software architecture: what servers (apache, nginx, squid, varnish etc) to use and how they interact with each other one server in one machine? how many mysql servers. how many apache, nginx servers and so on. how the "machine court" looks like. are there any good books about this area?

• route command not being executed in rc.local

  - by user1265478

  I tried adding route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0 to my Fedora rc.local file, but it's not being executed when Fedora boots up. What can I do to fix this? update: i changed to the full path cmd in my rc.local /sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0 but its not being executed. I change it to sudo /sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0 it still doesnt work although it works when i manually enter it in the terminal.

• Distributed filesystem across a slow link

  - by Jeff Ferland

  I have an image in my head where a link is too slow to realize the real-time transfer of files, but fast enough to catch up every day. What I'd like to see is a master <- master setup where when I write a file to Server A, the metadata will transfer to Server B immediately and the file will transfer at idle or immediately when Server B's client tries to read the file before Server A has sent it. It seems that there are many filesystems which can perform well over fast links, but I don't know of any that do well with a big bottle neck and a few hours of latency.

• DHCP server can't see other machines

  - by William

  Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

• iptables redirect single website traffic to port 8080

  - by Luke John Southard

  My goal is to be able to make a connection to one, and only one, website through a proxy. Everything else should be dropped. I have been able to do this successfully without a proxy with this code: ./iptables -I INPUT 1 -i lo -j ACCEPT ./iptabels -A OUTPUT -p udp --dport 53 -j ACCEPT ./iptables -A OUTPUT -p tcp -d www.website.com --dport 80 -j ACCEPT ./iptables -A INPUT -m conntrack --cstate ESTABLISHED,RELATED -j ACCEPT ./iptables -P INPUT DROP ./iptables -P OUTPUT DROP How could I do the same thing except redirect the traffic to port 8080 somewhere? I've been trying to redirect in the PREROUTING chain in the nat table. I'm unsure if this is the proper place to do that tho. Thanks for your help!

• Open file without specifying exact location

  - by person

  Say I have a file in some obscure directory that I want to open and edit. I don't want to do something like this... vim ~/foo/bar/blah/doh/ugh.txt I'd rather be able to say find this file and open it. I know there are commands like locate and find to find a file or directory, but I'm not sure whether these can (or even should) be utilized in what I'm trying to do. Basically, what is the simplest way to open a file with a program w/o specifying its exact location? (In cases where there isn't another file with the same name in the entire system, and cases where there are multiple).

• Ubuntu's garbage collection cron job for PHP sessions takes 25 minutes to run, why?

  - by Lamah

  Ubuntu has a cron job set up which looks for and deletes old PHP sessions: # Look for and purge old sessions every 30 minutes 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] \ && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 \ -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir \ fuser -s {} 2> /dev/null \; -delete My problem is that this process is taking a very long time to run, with lots of disk IO. Here's my CPU usage graph: The cleanup running is represented by the teal spikes. At the beginning of the period, PHP's cleanup jobs were scheduled at the default 09 and 39 minutes times. At 15:00 I removed the 39 minute time from cron, so a cleanup job twice the size runs half as often (you can see the peaks get twice as wide and half as frequent). Here are the corresponding graphs for IO time: And disk operations: At the peak where there were about 14,000 sessions active, the cleanup can be seen to run for a full 25 minutes, apparently using 100% of one core of the CPU and what seems to be 100% of the disk IO for the entire period. Why is it so resource intensive? An ls of the session directory /var/lib/php5 takes just a fraction of a second. So why does it take a full 25 minutes to trim old sessions? Is there anything I can do to speed this up? The filesystem for this device is currently ext4, running on Ubuntu Precise 12.04 64-bit. EDIT: I suspect that the load is due to the unusual process "fuser" (since I expect a simple rm to be a damn sight faster than the performance I'm seeing). I'm going to remove the use of fuser and see what happens.
