  • How to maintain a SSD drive on Ubuntu ?

    - by Julien Nicoulaud
    I am running Ubuntu 10.04 on a Intel X25-M PostVille 160 Go SSD drive. How can I tell if there's something wrong ? What should/can I do to maintain its performance/health ? Should I use TRIM and how often ? This may look as a duplicate of this question, but I am more asking in term of good practices and learning how to use this new technology the right way...

  • GParted tells me my partition has 1.30 GiB used space but I cannot access its contents

    - by reprogrammer
    I've a ext4 partition (/dev/sda7) for my Linux. And, another (/dev/sda5) for keeping my data. When I installing Ubuntu 10.04 LTS, I set the mount point of /dev/sda5 to "/" and that of /dev/sda5 to "/data". GParted tells me that 1.30 GiB out of 70.12 GiB of /dev/sda5 has been used up. But, the mounted directory "/data" is empty. So, it looks like that my data is there but I cannot access it. Besides, when I set the mount point, I didn't check the "format" box. So, it shouldn't have been formatted. How can I check whether the partition has been formatted? How can I recover my files?

  • Changing PATH Environment Variable for all Users. (Ubuntu)

    - by Wally Glutton
    I recently compiled Ruby Enterprise Edition (REE) on an Ubuntu 8.04 server. I would like to update my PATH to ensure this new version of Ruby (found in /opt/ruby_ee/bin) supersedes the older version in /usr/local/bin. (I still want the old version around, though.) I would like these PATH changes to affect all users and crontabs. Attempted Solution #1: The REE documentation recommends placing the REE bin folder at the beginning of the global PATH in /etc/environment. I altered the PATH in this file to read: PATH="/opt/ruby_ee/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" This did not affect my PATH at all. Attempted Solution #2: Next I followed these instructions and updated the PATH setting in /etc/login.defs and /etc/crontab. (I did not change /etc/sudoers.) This didn't affect my PATH either, even after logging out and rebooting the server. Other information: I seem to be having the same problem described here. I'm testing using the commands "echo $PATH" and "ruby -v". My shell is bash. My .bashrc doesn't override my PATH. Yes, I have heard of the Ruby Version Manager project. ;)

  • mailman not relaying email to external address

    - by gozzilli
    I have a setup of mailman with postfix on an ubuntu server 12.04. My problem is that mailing list emails are not forwarded to email addresses external to my institution. However the initial welcome email is received by everyone, internally and externally. in fact, a simple email from command line with mail is successfully sent to anyone after that, mailing list emails are only forwarded to internal addresses. the domain name I'm using for the server is not that of my institution who is hosting the server. Here is my main.cf: myorigin = sub.myinstitution.tld mynetworks = 127.0.0.0/8 xxx.xxx.xxx.xxx/16 # this is my institution ip range relayhost = smtp.myinstitution.tld inet_interfaces = loopback-only local_transport = error:local delivery is disabled virtual_alias_maps = hash:/etc/postfix/virtual smtpd_recipient_restrictions = permit_mynetworks myhostname = mywebsite.tld mydestination = $myhostname, localhost.$mydomain, localhost I also found these two links on serverfault and ubuntu forums, but neither of these solutions seem to do the trick for me. Any help would be much appreciated.

  • How can I remove the ssh last login info?

    - by Gnijuohz
    Whenever I log into a server using ssh. The prompt gives me "last login" information. I was wondering where this information comes from. How can I remove this record so when someone else log into the same server, the person would see my login info with my ip in it? So how can I do this? For the record, I am not hacking someone's computer and the server runs Ubuntu 12.04. EDIT: which file logs this kind of information? If I find the file, then I can do anything to it as root. Thanks.

  • Cut (smart edit) .mts (AVCHD Progressive) files un Ubuntu Lucid

    - by pts
    I have a bunch of .mts files containing AVCHD Progressive video recorded by a Panasonic camera, and I need software on Ubuntu Lucid with which I can remove the boring parts, and concatenate the interesting parts, all this without reencoding the video stream. It's OK for me to cut at keyframe boundary. If Avidemux was able to open the files, it would take about 60 hours of work for me to cut the files. (At least that was it last time I tried with similar videos, but of a file format supported by Avidemux.) So I need a fast, powerful and stable video editor, because I don't want that 60 hours of work go up to 240 or even 480 hours just because the tool is too slow or unstable or has a terrible UI. I've tried Avidemux 2.5.5 and 2.5.6, but they crash trying to open such a file, even if I convert the file to .avi first using mencoder -oac copy -ovc copy. mplayer can play the files. I've tried Avidemux 2.6.0, which can open the file, but it cannot jump to the previous or next keyframe etc. (if I make it jump to the next keyframe, and then to the previous keyframe, it doesn't end up at the original keyframe, sometimes displays an error etc.). Also I'm not sure if Avidemux 2.6.x would let me save the result without reencoding. I've tried Kdenlive 0.7.7.1, but playback is very choppy, and it cannot play audio at all (complaining that SDL cannot find the device; but many other programs on the system can play audio). It would be a pain to work with. I've tried converting the .mts file to .mkv using ffmpeg -i input.mts -vcodec copy -sameq -acodec copy -f matroska output.mkv, but that caused too much visible distortions in the video in both mplayer and Avidemux. I've tried converting the .mts file with TsRemux.exe, but Avidemux 2.5.x still can't open that file. Is there another program to cut and concatenate the files? Is there a preprocessor which would create a file (without reencoding the video) on which Avidemux wouldn't crash?

  • On freenode, how do I keep NickServ from messaging me when I log in?

    - by Matthew
    I have Empathy set to run whenever I log in to Ubuntu. As soon as Empathy connects to freenode, I get these messages: This nickname is registered. Please choose a different nickname, or identify via /msg NickServ identify . You are now identified for [my name]. This is pretty annoying, since Empathy handles identification for me anyway. Is there any way to keep this from happening?

  • Ubuntu 10.04 bind9 local zone include files and apparmor

    - by Gilgongo
    Rather than putting all my zones in one named.conf.local file, I'd like to have them in groups that I can manage as separate files. So, I've tried putting the following into named.conf.local: include "/home/zones/group1.conf"; include "/home/zones/group2.conf"; include "/home/zones/group3.conf"; However, when I restart named, I see "permission denied" errors in the logs. Ubuntu uses apparmor for bind, so I also added the following in /etc/apparmor.d/usr.sbin.named: /home/zones/group1.conf r, /home/zones/group1.conf r, /home/zones/group1.conf r, Now, when I re-start named, all appears to be well. Zones are loaded (I think). However, a day or two later, I see my secondary name server complaining that the primary is telling it that it's not authoritative for those domains. I then have to put all the domains back into the named.conf.local file again. How can I get bind9 to use include files in this way? I don't know much about apparmor, so that may or may not be the issue here, but I've used include files in this way on Debian OK.

  • How do I correct the kernel version loaded by Grub2 in Ubuntu 12.04

  • Apache 2.4 with PHP-FPM

    - by tubaguy50035
    I'm trying to setup Apache 2.4 with PHP-FPM 5.4 using the new modules with Apache 2.4. The following is what I have currently in my virtual host file: <VirtualHost *:80> ServerAdmin root@localhost DocumentRoot /var/www #Directory permissions <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Require all granted </Directory> CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> I have PHP-FPM running using Unix sockets with a sock file located at /var/run/php5-fpm.sock. How do I proxy my requests to this sock file? I've seen some sites say to use ProxyPassMatch and others are saying Rewrite Rule. Are there pros or cons on either side? Also, most sites I'm seeing are showing ProxyPassMatch with a regex to only pass .php files. Could I also send it .html files? For whatever reason, we have a ton of PHP inside .html files. Edit: As noted in the comments, it looks like mod_proxy_fcgi doesn't support Unix sockets. Is there another module I should be using?

  • Nvidia restricted driver = invisible menus when using VNC

    - by Fred Hamilton
    I'm installing 9.04 on an HTPC, so I will often VNC in to work on it from my laptop. After the initial install, I updated everything, and it all went fine. I was able to VNC using Ubuntu's built-in "Remote Desktop" with no problems. I then installed the 180.xx restricted nvidia drivers and rebooted. Everything worked fine on my TV, but when I VNC'd into it, all I could see was the background and title bar. When I'd pull down a menu, the menu was visible on the TV but not over the VNC link. I assume that means the GUI was now using some sort of overlay for the menus, which is fine, but what's the best way to make them visible over VNC? Clarification: I know I can turn off all visual effects and solve the problem, but I'm looking for a way to see the menus over VNC while keeping the GUI pretty...

  • Address VMWare Fusion Linux guest by hostname?

    - by amrox
    I have a Ubuntu Server 9.04 image set up in VMWare Fusion 3.0.0, using the NAT option for the guest's network connection. From the Mac host, I can ssh to the linux guest just fine using it's IP address, but I would like to be able to refer to it by hostname for connivence. ie: mac-host:~ ssh [email protected] I had a similar setup using Parallels a couple years ago, but I don't remember how it was set up. It may have "just worked". Any suggestion on how to make this work?

  • Move a screen session back to its original PID

    - by cron410
    Installed McMyAdmin (minecraft manager) on Ubuntu 12.04 32 bit. Wrote my own service to start McMyAdmin (.net app running in Mono) in its own screen session, and be able to inject proper McMyAdmin commands into that session with the init.d script. Its been running great! Today, I decided to start installing a Source dedicated server (counterstrike pro mod) I determine its going to be a long download process so I quit the process and fire up a fresh screen session called "source". I paste the command in, but it has a space at the begining and bash complains of ignoring semaphores or some such. I detach and reattach the session. Its sliding like butter. I ctrl+a-d out of the session and start exploring the new folder structure and figure out where I need to place a symbolic link. I go to resume that screen and this is what I see: $screen -r source There are several suitable screens on 20091.source (12/02/12 22:59:53) (Detached) 19972.source (12/02/12 22:57:31) (Detached) 917.minecraft (11/30/12 15:30:37) (Attached) It appears I am connected to the minecraft screen?!?!?! So I attach to the other screens one at a time. minecraft is running in 19972.source and sourceds is running in 20091.source So how the hell did I move the minecraft process to another session called source and my main terminal is now "attached" to the minecraft screen? more: I just used exit to quit the putty session, then logged back in, its still the same. did that 3 more times and now the minecraft screen is gone and everything is acting as it should except, of course, for the session name and start time of the "new" minecraft screen. Should I just submit this as a bug for GNU screen?

  • Storing secure keys on Ubuntu web server

    - by Sencha
    I'm running Ubuntu 12.04 Precise with a DUNG (Django, Unix, Nginx & Gunicorn) environment and my app (as well as various config files) is stored in a python virtual environment inside /srv, which the www-data user has access to. The nginx & gunicorn processes are all run as www-data. My web app requires secure credentials which I am storing in an environment.sh file. This file contains various exports and is run using source before the gunicorn processes execute. My concern is the location of the environment.sh file and it's permissions. Will it be okay storing this file inside the /srv folder where the www-data has access to it? Or should it be stored and owned by root somewhere else such as /var/myapp/environment.sh? Also, regarding the www-data user, if any of my web processes (which are run as www-data) are compromised and someone gains access to them, does that mean that the user could potentially read any file on the system, even if they can't write? Including my secure keys?

  • I would like to edit the layout of my keyboard just a bit - what's the best way?

    - by Codemonkey
    I'm using an Apple keyboard which has some annoyances compared to other keyboards. Namely, the Alt_L and Super_L keys are swapped, and the bar and less keys are swapped ("|" and "<"). I've written an Xmodmap file to swap the keys back: keycode 49 = less greater less greater onehalf threequarters keycode 64 = Super_L NoSymbol Super_L keycode 94 = bar section bar section brokenbar paragraph keycode 108 = Super_R NoSymbol Super_R keycode 133 = Alt_L Meta_L Alt_L Meta_L keycode 134 = Alt_R Meta_R Alt_R Meta_R I did this by identifying the keys using xev and the default modmap xmodmap -pke and swapping the keycodes. xev now identifies all my keys as correct, which is awesome! I can also use the correct keys to type the bar and less than symbols. (I followed this answer on askubuntu: http://askubuntu.com/q/24916/52719) But it seems the change isn't very deep. For instance, the Super key is now broken in the Compiz Settings Manager. No shortcuts involving the Super key works (but the Alt key does). Also the settings dialog for Gnome Do doesn't heed the changes in xmodmap, and I can't open the Gnome Do window anymore if I use any of the remapped keys. So to summarize, everything broke. I would like a deeper way of telling Ubuntu (or any other Linux distro for that matter) which keys are which on the keyboard. Is there a way to edit the Keyboard Layout directly? I'm using the Norwegian Bokmål keyboard layout. Does it reside in a file somewhere I could edit? Any comments, previous experiences or relevant stray thoughts would be greatly appreciated - Thanks

  • Configuring Nagios BGP plugin on Ubuntu

    - by user141610
    I am trying to configure nagios check_bgp_neighbors plug-in on Ubuntu and followed README file of check_bgp_neighbors plug-in. I have made following changes: define command{ command_name check_bgp_all command_line $USER1$/check_bgp_neighbors -H $HOSTADDRESS$ -C $USER3$ -n $ARG1$ -n $ARG2$ } to define command{ command_name check_bgp_all command_line /usr/local/nagios/libexec/check_bgp_neighbors.sh -H xx.xx.xx.49 -C xx.xx.xx.50 And define service{ use server-service hostgroup_name svc-bgp1 service_description BGP Check 1 check_command check_bgp_all!10.0.0.1!172.16.0.2 } to define service{ use generic-service hostgroup_name svc-bgp1 service_description BGP Check 1 check_command check_bgp_all!xx.xx.xx.50 } xx.xx.xx.49 is the IP of the host router and xx.xx.xx.50 is the IP of eBGP neighbour. After that it shows critical status. I know my command is not correct but cannot detect the problem. I learned that in this plug-in user-name and password of the host router are required but don't know how and where to provide it. Nagios log does not show any error message.

  • Grub os-probe showing deleted Windows installation

    I recently purchased a Dell Vostro notebook with Ubuntu Netbook edition 10.04 pre-installed. I tried adding a partition and installed Windows XP but it didn't work out due to too many partitions in the system already. Now I have restored the laptop to factory setting using Dell Utility partition and the Windows partition is completely deleted, however my grub2 still shows Windows on /dev/sda2 sudo os-probe Microsoft Windows XP Professional (on /dev/sda2) Any ideas how to remove it from grub? I know I can remove /etc/grub.d/30_os-probe but I am more interested in why os-probe is showing the deleted partition.

  • Ubuntu 10.04 boot splash screen and themes broken

    - by thezachperson31
    I recently upgraded to the release candidate of Ubuntu 10.04. Since then, two problems have occurred and persisted: the boot splash screen has reduced down to a black screen with random color blocks/text/gibberish at the top; and the themes are broken, as in the light themes have checkboxes in menus the same color as the background, and the dark themes don't correctly change the font colors in the top menu. Help? On a side note, is there a need to upgrade from 10.04 RC to LTS?
