Ubuntu :: Server Was Set To Automatically Install Updates, And Stopped Working While Was Away?
Jul 1, 2011
My server was set to automatically install updates, and stopped working while I was away. When I got back to it, it now has a boot menu to choose between kernel versions, with no default or timer. So I pick one, and there are heaps of other problems. the /home partition isn't mounting, despite the fstab being unchanged. I can mount it manually using mount with no problems /var/syslog has nothing since April, and isn't updating when I reboot, so I'm not sure what I can cut and paste to here for you all to look at. The networking isn't running, in fact, most of the network interfaces aren't even showing up.That's just what I've identified so far. I have no idea where to start. I can't find anything wrong other than the fact it's not working.I can't copy and paste any output at this point, because I can't ssh,
We are running CentOS 5.4 x86 on ESX 4 Server. We have a busy Help Desk, a Forum and several name-based websites running. Weve been using CentOS for this 'purpose for several years (different versions) and so far we have never had a problem. On Saturday, I applied all the latest updates including the Kernel updates. I rebooted the server and all seemed well until Sunday morning when I didn't get my Logwatch in the mail. Then I got a telephone call from a customer asking me why I hadn't responded to a Trouble Ticket he had created on Saturday afternoon (creating a TT sends an email via sendmail to all the support staff). I did a few tests and sendmail has just stopped working. The Logwatch had been created and had been sent to root, but all mail for root is redirected to my Mail Server on e different box (GroupWise). There was nothing wrong with the mail server, but sendmail has just stopped.
Fortunately I had created a snapshot before I applied the updates, so I reverted back to the snapshot and mail started working again, but I lost 2 days info because I had run the backup before I applied the patches. Now I see there are 132 Updates available, but there is obviously a problem somewhere in there!
I haven't used my VB for a few weeks however all of a sudden it refuses to work for my normal non-root user. It's almost as if it can't find libraries in the /opt/VirtualBox directory. Initially it refused to start completely so I linked the required libs into /usr/lib64 ( yip real hack. Then it started but a vm would not start, and comes up with an error about a missing lib again which is definitely there. My non-root user is in the vb group and nothing besides system updates has changed. vb 3.2.10 slack64-current.
I installed apache 2.2 with centos 5.5. When I typed service httpd stop, apache stopped. Then in a minute, it automatic start again. I don't use crontab, and I tried 'chkconfig httpd off', but it still automatic start. I used 'ps -ef' to look process, I saw, httpd have PPID is 1, and then I find PID 1 have PPID 0.
I successfully set-up an FTP server, that worked great and perfectly, but after restarting the computer, it has stopped working.None of my router's settings have changed. I restarted the vsftpd process.
There are a few threads about this but none seem to me.I have 3 machines setup with a nfs home directory on machine 1.I have created keys using ssh-keygen -t rsa (and left everything blank), then as user on machine 1 run
this used to work until I upgraded to ubuntu 11.04 (from 9.04), and now it requires a password to ssh. I have tried several times deleting ~/.ssh/* and recreating, to no luck Below is the results when I try to ssh into -2 from -1:

(dumb question, but shouldn't the offered RSA public key be id_rsa.pub rather than id_rsa?)
I have a laptop that was working fine with 10.04 LTS. Today, I did a full 10.10 install and now my wireless is not working. Thinking it had to do with 10.10, I did a full install back to 10.04 LTs. Wireless is still not working. I tried installing the driver for my laptop's internal wifi using ndiswrapper, but that didn't work either. I have another laptop that is identical to the non-working one, with the exception that it is running a Celeron processor and non-Nvidia graphics. Otherwise, they are identical with respect to the wifi adapter. The Celeron machine is giving me absolutely no problems.
I'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1. I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT STATE SERVICE
25/tcp open smtp 80/tcp open http 110/tcp open pop3
For more than a year I was happily using my Fedora 11 remotely through VNC over ssh. I was using desktop 0 on port 5900 so people at the office can see what I am doing.
Yesterday I upgraded to Fedora 12, then 13 and then 14. I installed all updates of F14. All went well until I came to use this server from home as usual. The server was not responding.
I brought up /etc/X11/xorg.conf from a backup tape because I discovered that it is there that screen 0 is set and not in /etc/sysconfig/vncservers and rebooted. No success!
At the command lsof | grep LISTEN, I could not see a listener on port 5900
I activated screen 1 on port 5901 and I could log in OK and with lsof I could see listeners for ports 5901 and 6001 but I need screen 0!
During the day I tried many things including removing the vncserver packages with yum and re-installing them, removing the .vnc folder in the user home folder and starting from scratch. The server is still refusing connection!
i have just setup a firewall using iptables on centos 5.3 but there's an issue with ftp i can connect and i can login when i give command "ls" it says entering passive mode and afterwards it times out do you know why? i have port 21 open in my firewall but still....
sometime ago i have setup a nice Debian FTP server. and left the company. everything was working fine for about 5 month, administrator was able to login to root, do changes and manage system, etc. Suddenly he told me that he cannot login via PUTTY, the root user and pass say Access Denied.Looked all over the web for at least a REASON, but did not find anything. I suggested to go and do passwd reset, via runLevel 1. i hope this helps him. But i am still curious why all of the sudden, in a locked down room, where only one person has access root get disabled.
Well I guess the topic says it all. I've recently upgraded to Maverick from Lucid all went smoothly until i restarted and realized that the remote desktop server included stopped functioning all of a sudden. tried other vnc servers with no luck.
I am using Ubuntu 10.04. In the summer a few months back, I managed to get my ancient HP Laserjet 6L printer working via a wired D-Link-DPR 1061 print server and Netgear network switch. This was even though it was not on the print server's compatibility list. A couple of months later it stopped printing and I have not been able to get it going again since.
The print server has one parallel port (used by the 6L) and a couple of USB ports which I don't use.
I have been going through the Ubuntu add printer wizard. The print server can connect via an IP address. I am using its device URI: lpd://ip address/dlk-portname
I have tried all 5 HP laserjet 6L drivers that come with Ubuntu without success. I have the foomatic/ljet4 [en] currently selected. When I try to print a test page nothing is printed and when I do a print self test I get this message:
CUPS SERVER ERROR There was an error during the CUPS operation: 'client-error-document-format-not-supported'.
By, the way I also have a Windows 7 PC and managed to get the 6L working with same print server using the XP drivers, but every so often it stops working. A reinstall gets it going again.
My desktop computer has another Linux distro on it. Wired networking was working fine. I wanted to try Ubuntu 10.10 so I installed it on a spare USB HDD. After install, networking still worked on both distros.
I moved the USB HDD to my win7 laptop and Ubuntu 10.10 booted fine. Once booted, Ubuntu asked to configure wireless on the laptop. I tried to do this but it did not work.
Therefore, I moved the USB HHD back to the desktop and booted. Now the wired network does not work from either Ubuntu or other distro (fedora 14). And to top it all off, the wired network will not work even from the Ubuntu live CD.
I have checked all connections, switches & cat5 cables to my desktop computer. I can still access the network and internet from my laptop (in win7) so I do not believe it is an infrastructure issue. I can confirm that everything works from the cable out of the back of the desktop through to the internet.
Here is the output from the usual troubleshooting commands in Ubuntu 10.10 code...
It seems that the touchpad has stopped working on my Acer travelmate 2490. I don't use it often, so that I am not sure when it occurred, but I suspect it was after my update to KDE 4.3.
My phpmyadmin stopped working. I reinstalled it and it gives error #2002. I found that this error is from mysql, which i couldn't repair and i begin to reinstall it. First I was with Debian 5.03, but i played with /etc/apt/sources.list and after upgrading
I have now 5.05
The problem is that when i install mysql-server a dependency appear in mysql-server-5.0. I follow this instructions[url] and after sudo apt-get install mysql-server mysql-client
I get this error:
Code:
How can i fix this dependency? I didn't find anything relative in google.
mysql-server-5.0 --configure gives error: command not found
I uninstalled all related with mysql and execute dpkg --purge mysql-server then reboot and run first apt-get install mysql-server-5.0 mysql-client-5.0 and then apt-get install mysql-server mysql-client There was no error
Code:
But there was another error when run mysql -u root -p
My mail server stopped working this weekend, when I got in today I restarted and all the emails came through. The panic_log shows: daemon: accept process fork failed: Cannot allocate memory several times over the course of a few minutes. Can anyone give me advice on troubleshooting this one?
My plex media server suddenly stopped working after years of no hassle use. This is the output of cat /proc/version = Linux version 3.2.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.65-1+deb7u2
My problem is similar to this forum thread viewtopic.php?f=5&t=121945 where I can get it to start by running Code: Select all/usr/sbin/start_pms & but it's not my normal server configuration. I added a couple files to it and it seems to work except it doesn't start when I reboot. I have to run that command again.This is the init script I've been running for years...
Code: Select all---- #!/bin/sh ### BEGIN INIT INFO # Provides:Â Â Â Â Â plexmediaserver # Required-Start:Â Â $remote_fs $syslog $networking # Required-Stop:Â Â Â
[code]....
My Debian skills are lacking to know how to proceed with troubleshooting what could have happened. Everything else seems fine, I just can't seem to get this application to run at startup or get back my old configuration...
After using fedora 11 for a month or two now the ethernet gave out on me tonight. However if I switch to my ubuntu or windows XP install it runs fine. I made no recent changes to network connections, and no installed programs that should effect it.
I have tried, restarting, older kernel, restarting services, and clearing the DNS Cache. The specific error I get is that "Firefox can't find the server", and most other applications return similar. I can however ping websites still. All other computers on the network are running fine, and booting into another system the internet will work. Just not for fedora.
I have been using my laptop as a development machine for a few months now, developing php/mysql applications, and testing them offline via the same laptop by pointing the browser to url.
But a few days ago, my url stopped working and I discovered that it will now only work if I have an active internet connection plugged in. Why has this happened and how to I fix my test server so localhost works with or without an internet connection via an ethernet cable.
I try to update my computer through the updater and it does not work, it fails, so it brings me to YaST, and that fails to... what is going on? Why are my updates failing?
I am running Suse 11.0 and the system had stopped working. I booted from the disk and chose repair system. Now I can get to the Give root password for login and it accepts the password, but I get the line (repair filesystem) #
I have a machine running with slackware64 13.1 and vnc servers is installed on it. It worked for months until yesterday, when I couldnt connect to the machine remotely.
I have 2 vnc "users" on this machine, root and "user". Each have their own desktop. Root has desktop :1 and user had desktop :2. Simple enough.
VNC servers is started via /etc/rc.d/rc.local with the command:
Code:
Code:
It worked flawlessly. I use the very same configuration on my home server, never had a glitch.
From the "distant" machine, I get this error when I try to connect:
Code:
Unable to connect to VNC server
What has changed so it no longer works? I assume its not a network problem since the machines are all located in my home network and there is no firewall or router in between them.
My self-built PC had a BT wireless adaptor in it which worked, albeit after a bit of a faff, with Ubuntu 10.10 in connecting to my BT HomeHub2.
When I came to use it last week it would not connect. I'd not changed any hardware but I had been applying regular updates via Update Manager.
Bearing in mind the "faff" factor, I decided to try a different (Edimax) wireless card but got the same result. Upgrading to 11.04 has made no difference either.
It does *try* to connect but fails, so I think the card is installed correctly. I've also tried a full reset on the HomeHub and the setup works fine with W7.
When I run the updates option on it, it tells me that the virus engine is out of date. However, it does not automatically download it, nor does it suggest a site. Is there a way to get the program to automatically download updates? If not, can you direct me to a site that would have the updates?Also, if there is a more newbie-friendly or perhaps more reliable anti-virus program, could someone direct me to it?
On my iSCSI booted server, the standard Karmic Server install CD installs a system that won't boot.This is caused by a bug in the initscripts. This bug is solved in an update of this package. How do I get the updated version of the initscripts package on my install CD?
How can I uninstall grub? I have have dual boot between Gentoo and Ubuntu and I want to use the grub, that is on Gentoo partition, as its my main system. I would not care about it as it takes almost no space, but Ubuntu automatically restores its own bootscreen after updates. This is annoying... How to get rid of it?
For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.
Is there a package in YUM now that automatically updates amavisd-new to version 2.6.4??? My VM comes stock with version 2.5.4 and i absolutely CANNOT update it to 2.6.4 due to incompatibility issues in Maia Mailguard. When I do the package upgrade I don't understand but i specifically do NOT choose amavisd-new to be updated and everytime I check to see my latest version it is at version 2.6.4 I don't get it am I missing something? What can be causing my package to always get upgraded to the new version when I am not upgrading it.
I have spamassassin 3.3.1 clamav 0.96 postfix 2.3.3
