Ubuntu Servers :: SSH Stopped Working - Cannot Restart
May 26, 2011
I am running a headless home file server with ssh, samba, webmin and webgui for Transmission. It was all working fine on my lan until I tried to set ssh to listen on a different port (I read it was safer to do so if you wanted access from the internet). Now I cannot ssh into my server and as far I can tell using webmin the ssh process is no longer running and I cannot restart it. I have restored my unmodified sshd_config file. After restoring my original config file and rebooting I am back and working.

Today i made an update using Webmin, and after that php stopped working, instead of running the files it launches a download. So i checked what was going on, and php module was disabled in apache config. When trying to enable it, it said the file "/usr/lib/apache2/modules/libphp5.so" did not exist, and indeed it disapeared. I tried to reinstal php and apache (with and without --purge, through apt) and it didn't solved the problem.
Also i tried copying the file from another machine, also without success (this time it shows " Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP.") Dont know what to do now, im kinda desperated here because this machine hosts my website =P

I am not sure what happened, but my .htaccess file is no longer working for my 301 redirects. I did have a hard time getting it working a few weeks back (when I first set it up), unfortunately I did not document it well. Main question is for multiple sites getting redirected, do I want the additional sites listed as aliases? My original setup virtual host config listed seven additional hostnames as aliases.
I later had difficulty with google listing these secondary domains within search result and hurting my page rank. So I setup 301 redirects, and from memory, I had to leave the alias names for the .htacces 301 redirect to work. Now it won't work either way. Can anyone tell me if the aliases need to be in place? Do I need to setup individual vhost files and add an .htacces 301 for each? What is the preferred way to do this? I tried reloading apache2 but it did not help.
Permissions for .htacces:
Code:
-rwxr-xr-x 1 eric www-data 866 2010-04-14 12:06 .htaccess
Attaced is my .htaccess. It resides in the site root directory. Also attached is the virtual host config file.
httpd.conf
Code:
NameVirtualHost *
NameVirtualHost *:443
AddHandler cgi-script .pl
RewriteEngine On
I'm still not sure after hours of reading the various how-to's, what should the file permissions be for the .htaccess. I have not performed any updates during the period it was working till now.

I run Samba version 3.4.7 as a Domain server for our company, and recently we reorganized our IP-addresses. And the Samba server also got a new IP-address. (192.168.1.60 -> 192.168.1.22). However, now new computers can not join the domain, and old ones can not connect to it correctly (they get a temp profile).
Windows XP gets a temp profile when connecting, and when trying to join a domain I get this error "A domain controller for the domain HAWAR3 could not be contacted. Ensure that the domain name is typed correctly. If the name is correct click Details for troubleshooting".
When trying to connect Windows2008R2 (already a member) it says:
"There are currently no logon servers available to service the logon request."
My guess is that is is some problem with WINS or something.

I have just booted up to do some local work on my website and apache 2 has start throwing 403 error's at me? phpmyadmin and other alias's I have setup work but the main root just 403's on me?? It has been working away flawlessly for months now. No system upgrade has recently updated Apache and I can see no errors in my set up files!
My default setup file:
Code:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /home/gavin/wwwsite
<Directory "/home/gavin/wwwsite">
Options +Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from all

I run ubuntu 10.10 with apache2 and have 2 virtual hosts set up
here is an example of one of the virtual hosts
<VirtualHost *:80>
ServerName blah.endofinternet.org
ServerAlias blah.endofinternet.org
ServerAdmin davidboychuck@gmail.com
DocumentRoot /var/www/blah
[Code]....
Everything was working perfectly until i changed the internal ip of my router from 192.168.1 to 192.168.192 and now virtual hosting no longer works. As far as I can tell everything is setup correctly. I made no changes to the configuration files. Vhosts just literally stopped working. I've tried clearing dns cache not sure what to do at this point. I have tried to a2dissite and then a2ensite and reload the configurations but it literally just seems like apache is not looking for the vhosts in /etc/apache2/sites-enabled even though my apache2.conf still includes them
#Include the virtual host configurations:
Include sites-enabled/
From the apache error log:
[Sun Apr 03 16:41:50 2011] [error] [client 66.249.72.208] script '/var/www/index.php' not found or unable to stat
[Code].....
It looks like it's just not trying to use the vhost document root because when i go to blah.endofinternet.org it just takes me to the default site.

I am running Fedora 11 with an Oracle 11g database installed. I came to check on it and found out that the oracle service had stopped. I also have a script that gets run by cron every minute. I noticed that the last entry in the log /var/log/cron was March 24 at 4:26. Which was really close (not exactly to the second but within a few minutes) of the last log entry in the database translator logs (the database was processing data and it outputs a log).
I rebooted the machine and cron started running again, but I can't get the oracle service to start again. Normally it runs at startup, but if I need to run it or check it, I use:
Code: /sbin/service oracle restart
Is there another log that I could look at to see what would be the cause of the stoppage? How to get the oracle service started again?

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

resubscribed to Rapidshare and in the past could easily download my friend's discussion papers using the file manager called DTA that integrates into Firefox. I have taken out a new subscription to RS and instead of getting the files I am receiving small html referer files. In theory this should be corrected by ticking a direct download setting on RS, but it is making no difference. I can manually download the files so I am certain the files are on RS in full form. I am also successfully auto logging into RS and this means the name and password are being handed over correctly

After I installed Windows XP on my leftover partition, I decided to reinstall grub2.
Now when I reboot grub throws me in the grub shell, if I then type configfile /grub/grub.cfg it starts grub like its supposed to. Tho I cant seem to be able to go straight to the grub menu and no to the shell.

It was working fine. Now, when I boot the computer(9.10 32 bit), I get the message asking me about the certificate. But Pandora never seems to load. I tried to reinstall the AIR app, but it tells me that it is running. I can't find it though. If I try to open Pandora again, nothing ever happens

I got a call from a friend who did the distrubution upgrade from 9.04 to 9.10 and all was well for about 2 weeks and then his desktop icons disappeared. He kept running it that way and never looked for help until a couple of days ago he tried to plug in a card reader to get some pictures from his camera and nothing happened. that was when he discovered that he couldn't run Nautilus at all. I had him purge nautilus and reinstall it but then he couldn't even log in to Ubuntu. Very strange indeed. Anyone else experience this? After going over all the settings and finding them what they should be, I just installed 10.04 and all is well except that he lost a few photos.

I have been using Ubuntu for many years now and pressing ctrl + alt + d used to minimize all windows and show the desktop, but this stopped working with 10.10. I checked keyboard shortcuts but don't see a way to turn it back on there.

I have been using Ubuntu 10.10 for about a week now, I have had many, many problems, but usually figure them out by searching through this forum, except this time:I have an HP touchsmart tx2 1025dx laptop. When I installed it, everything worked great, sound, mouse, and even the touchscreen. Right now I noticed that when I press the button on by laptop which toggles the touchpad, it works but after it would freeze the menus, so that they would not drop down, I have confirmed this after many restarts. Now the touchpad has stopped working completely. Although if use the toggle button, it will still freeze by menus. It also somehow stops my keyboard from typing things into programs, like firefox, but still somehow the control-alt delete still lets me restart it.
My question is how can I reset the mouse settings/preferances to how they were when I installed? I found something a while back that was xorgconfig??? but it has since been taken out of ubuntu 10.10 (I read this somewhere, please correct me if I'm wrong.) I hope this is enough information for someone to point me in the right direction.Recap:Laptop Touchpad not workingWhen I press the toggle Touchpad button, messes up the menusUsing HP Touchsmart Tx2 1025dx LaptopLooking for a way to reset/restore sound preferences/settings or enable touchpad/ps: I was able to come here because the touchscreen is still working I ended up doing this:rm -rf .gnome .gnome2 .gconf .gconfd .metacitywhich reset ALL of my settings back to when I installed it, without deleting my programs or files.I found this here: http://linuxfud.wordpress.com/2007/0...re-installing/

I did a bunch of uninstalls and reinstalls lately, trying different distros. Now I'm back to Ubuntu but tab autocomplete in terminals doesn't work anymore. It is quite less convenient now to use the terminal. I tried changing interpreter to /bin/bash and it doesn't work. I use guake.

I have a media center box running Ubuntu 9.10 x64 and XBMC. One day sound just stopped working on it. I did not install any updates around the time this happened. I have tried using a known working sound card. I verified the main volume is up and everything else in alsamixer looks OK. I have tried connecting known working headphones. Confirmed the kernel sees the hardware and loads to module for it. Confirmed several audio applications have no sound. I've confirmed it is set to use the correct sound card. I even booted into a live disk of the same version if Ubuntu and audio works fine there.
No errors are produced by any application, they act like they are playing audio just fine. The only entries in the logs about this I can find is below.
