Ubuntu Servers :: Server Restarts When It Wants?
Jul 12, 2010
I'm currently using ubuntu desktop 9.10 (without desktop - I've removed packages) as OS on my server.But there's going on some strange thing ... There are about 8 users, and the thing is they many times user rar or some other disk-demanding programs. What I've noticed is that sometimes server will go with load over 20 (I know that's not good ...) and it will come down in few minutes and everything is OK, but sometimes it just restarts itself. I would like to disable that so it won't restart

Recently, I updated the kernel to the latest version and also installed Ruby and the Passenger module for Apache. The server was fine for a few days.However, today, it's been restarting randomly (usually a minute after I can log in).I tried booting with recover mode so I could view the logs for a longer period of time, but that caused it to restart before even allowing me to log in. Now, all boot modes will just cause the server to restart right after the GRUB messages appear.Our server setup complicates things. We have a RAID-1 mirroring for the /boot partition and a RAID-5 (software) for the / partition

is it normal having several security updates week after week in a 10.04 ubuntu lts server distro? Some of them even need a system restart, which I consider truly bad for a web server...

Changes I've made to the config files:
Connecting with PuTTy works fine with my public/private keys. But why does sshd start and then restart twice when booting? I tried looking in the logfiles under /var/log/ for anything with ssh/sshd but nothing shows up.

I want my server to automatically shutdown at 23:59 and startup at 8:00. The startup is handled through by bios but the shutdown is to be managed through cron. I thought I had this working, I actually swear I had it working because I thought the uptime command showed the appropriate uptime. I happened to be up and was streaming a movie from my server when at the time it should've shutdown it actually just restarted. If I run the shutdown -h now command by itself it works well but the scheduled command just restarts the server. Here is the what is shown when I enter crontab -e.

This is my first message. I manage a Virtual Web Server(provider Dattatec).
The problem is that the server automatically restarts... in /var/log/messages, i don't see any message:
I ask mi provider, and says that is because is out of memory... How can i check this? How can i know why my server restarts ?

I installed latest stable debian lenny. However when I want to switch to a virtual console by pressing Alt+Ctrl+F(1-6) the X server is restarted and I get the gdm login screen. When I kill gdm, virtual console switching works fine. How to switch a to a terminal and return to my X session by pressing Alt+Ctrl+F7?

If the server restarts, does the information in iptables get lost? I have seen a number of pages where people recommend readding lines or creating bash scripts to get it to work again. What about files like squid.conf, ncsa_auth files, etc.?

Ubuntu ver 8.04.1 and Bind ver 9.4.2
I've set this up as a primary dns server, Bind is the only thing running on it, no gui, etc. I followed the default settings so I have a named.conf, named.conf.options, and named.conf.local file.
I have a log file I labeled as named.log in this path /var/log/bind. I'm using logrotate to rotate out the file.
My problem is that after syslogd restarts in the morning. My named.log file don't start logging info until I restart Bind. The new named.log file gets created and the old files rotate out and compress. All of the other log files in /var/log, syslog, messages, mail, etc, rotate out and compress like they should, after syslogd restarts.
I know that I could restart Bind using Cron but I shouldn't have to.
Below are snips of the files I'm using.
I named this one 'bind' and it's in the directory /etc/logrotate.d

I'm making a clever backupsystem based on nfs and rsync.Basically, I export folders from the clients to a backup server, and the backup server processes them and makes backups.The backupserver mounts the folders during startup, but if a client restarts, then I guess it would unmount from my backupserver, right?What can I do to make it automount the folder whenever the client gets back up again?All the clients are static servers without much interferance, without any risk of external people tampering with them and without internet access. Security is not an issue, and any kind of shady compromisingcripts will do.However, installing software on them is tricky as I have to download packet for packet and transfer them via usb manually.

I have a problem with one a server installed with Debian 3.1, that is restarting almost every day at the same hour, 6,25 AM. Here are the messages obtained with #cerberus:/etc# grep -C 5 restart /var/log/messages
.....missing displays....
.....missing displays....
As I said, there are days when the system is not restarting, but more often it does. For example, on 6th October it didn't restart, but on 7th it did, and the messages are the same.

About two weeks ago I installed ubuntu 9.10 desktop with a dualboot to my windows 7, which was already on there. everything went fine, but I couldn't configure my wireless to work, so after a few days I gave it a rest and basically forgot about; I just stuck with windows. anyways, yesterday night I installed a program called solidworks on my system. I woke up this morning, turned on my computer, and this is what happened-
it turns on for about 5 seconds, but when it hits "grub loading", after about half a second it restarts. it's basically an infinite loop, until i throw in a cd or hit f8, but I don't know what to do with either of those options, so I'm kind of stuck.
I'm posting this in the ubuntu forums because I have NO idea what's wrong with it, and no idea of where to start. I've got both installation disks, but I don't know what to do when I put them in. I've got an intel pentium 4 processor, and like i said, i've got a dualboot with windows 7 and ubuntu 9.10.

I'm a WuBi user, and wanted to upgrade XP to 7, I've upgraded it partially when in XP. So as expected he messed up my grub.
But now I have the problem:
Every time I insert the Windows 7 DVD the pc says "Please press any key to boot up from CD/DVD" (as normal), but when I press the "any" key, the PC does absolutely nothing and just restarts.
Not to long ago I used the same DVD on another laptop for an equal upgrade (XP to 7) that went flawless.
My booting set-up is correct, cleaned the disc 500 times now, nothing out of the ordinairy done to my boot-screen or the BIOS... And as far as I know, no blue screen of death when installing the upgrade.
I haven't got a clue what I have to do.

this problem has really been getting at me, I can't figure it out at all. About a week ago, I came home from school and found that my computer was shut down (usually I leave it on), I started it up in Windows 7 and a Malware Bytes scan said it found a virus "clipb.exe". Well, I decided to remove it, and when booting up in windows it BSOD's saying IRQL_NOT_LESS_OR_EQUAL immediately at the login screen. Same result in safe mode and "last known configuration". Well, I decided to reformat just because I didn't want to go through too much trouble, and about a week later (today) it came back. I have no clue how, I was away from my computer. But the difference between this time and last time is, I can't start ubuntu at all. period. It gets to grub, and then after that gets to a black screen with no progress. The only thing I can do is ctrl+alt+dlt which restarts the computer.

whenever I use the files, which are mostly audio files (that is, I play them), after they are downloaded, the torrent files restarts again. So I have to wait for the file again to finish downloading so I can seed.

my X server restarts and boots me to the log screen when I start programs. I recently took the Nvidia card out of my computer and put in an ATI card. This is of course after uninstalling the Nvidia drivers through the restricted drivers interface. This worked out very well but eventually I went back to Nvidia. I removed the ATI drivers put in the Nvidia card and installed/selected the Nvidia drivers just as I did when I did this the other way previously. However now when I start just about any program the entire X server boots me back to the login screen.

My laptop restarts itself frequently - full restart back through the bios screen to the bootloader, not just logging-out. It happens in Ubuntu 11.04 (32 bit and 64 bit), the Gnome 3 live CD from [URL] (the Fedora based one, run from a USB stick) and even from the GRUB bootloader menu. I have tried two different harddrives and two sets of RAM (all combinations) and the restarts still occur. They even happen when the hard drive is removed and Ubuntu 11.04 is booted from USB. Windows XP Media Center is also installed on the laptop too but the restarts have never happened when in Windows (even though they can happen in the bootloader!).
The memtest86 GRUB menu entry loads the blue screen with the title and memory info etc. but it seems to stop there and I don't think it's actually doing any tests, so I haven't been able to do a memory test. In Windows I have not installed any wireless network or 4-in-1 card reader drivers (among others probably), which is a possible reason why it does not restart in Windows, although I don't think GRUB has drivers for either of these devices either. My laptop is an Acer Aspire 5630 with the following hardware:
CPU: Intel Core 2 5500 (1.66Ghz)
Memory: 2GiB DDR2
Graphics: Intel 945 (integrated)
Audio: Intel HD audio with Realtek codec
Wireless: Intel PRO/Wireless 3945ABG [Golan]
It does seem that sometimes the restarts are caused by touching the keyboard (i.e. they happen exactly when I hit a key) but they also sometimes occur when I am not even touching the computer at all.

My dads' hard drive went up a while back. So we got him a new one and installed Ubuntu 9.10 instead of windows. All was going well until About two weeks ago. The system restarts randomly. Not when anyone is doing anything in particular. Sometimes when we are using firefox, sometimes just sitting on the desktop, and never after any certain amount of time.Some times its after five minutes, some times after several hours. It's not a full out crash, the window for shutdown/switch user/restart comes up out of nowhere. When we close the window, it shows back up pretty quickly, but then the computer will just crash. While restarting, half of the time the computer won't make it past the bios screen before restarting again,and will continue the bios restarting cycle until the computer is unplugged. By the way, the system is a dell dimension E310 from 2005 with all of the original hardware minus hard drive inside, so if it is a hardware issue that wouldn't surprise me. Also, just one time after the restart I received the message "fsck from util-linux-ng 2.16" , if that helps at all.

I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?

I'm running Ubuntu 10.04, and ever since last upgrade a couple of days ago (I think), everytime I hit shutdown on the gnome-panel (admittedly, I haven't tried the command line shutdown) the computer restarts itself. This computer is dual-booted with Win 7, and the shutdown command there properly halts the system.

I had perfectly working lucid on my laptop (64 bit) which I installed from a live CD not wubi. I tried to upgrade with update-manager and everythingooked fine until I accidentally updated compiz from the cache before everything else finished. this made compiz stop working completely, which also broke metacity. I tried to fix this with multiple things: Downgrading compiz (failed to apply changes), sudo apt-get install -f, finishing the upgrade (see the following).
during the applying changes stage of the upgrade i got an error with almost every package it tried to apply (sorry I don't know what, but it said something about 'this package failed to upgrade and may be left in a broken state'. I let the upgrade finished and at the end it said 'Upgrade Finished but not all changes were successfully applied' and I shut down the computer. when I turned it back on everything looked fine until I past to the usplash screen. Then the screen went black, a bunch of error messages scrolled by too fast to read, and my system rebooted.
I tried recovery mode and another kernel choice at grub but all did basically the same thing. Windows still works as much as it usually does but I want my ubuntu back! I am OK with doing a fresh install if I can somehow recover a small amount of my data in my home folder. If you can tell me how to get into ubuntu from windows or something that would be great but I also need to know how to decrypt my home folder (I used the encrypting option in the installer)

I can chose Shutdown from the menu but the system gets to the point where the power supply should 'click' and shut off. It doesn't, it cycles and the system reboots. It wasn't doing this in 10.04, at least not towards the end prior to updating to 10.10 beta/rc/final. Also, 10.10 didn't do this either, until recently. (Current default = 2.6.35-22-generic)
Here's the funny thing though; if I choose a previous version from the GRUB2 menu, 2.6.32-21-generic for example, the login screen won't allow mouse nor keyboard control but will shut down normally w/ a single, momentary push of the Power Button. Now, there are folks w/ a seemingly similar problem, but in their case they can't shutdown at all. My trouble is a shutdown just triggers a restart.
