Ubuntu Servers :: 10.04 Shutdowns After Idle For A Couple Of Minutes?
Oct 12, 2010
I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing.
Whenever I go to sleep and there's no activity on my servers (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online!
I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active.

I've just installed Ubuntu 10.04 on a AMD processor with a nvidia graphic card in dual boot with windows xp. First the live-cd was already freezing after a couple of minutes so I had to install Ubuntu with the alternate cd. Now it freezes whatever I do after 2 or 3 minutes. I had exactly the same problem with the 6.04 version but I had only to remove powernowd from /etc/init.d/ to make it perfectly working. But unfortunately this file seems not to be there in this version.

I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.
I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.

So my Dell latitude E6400 running fedora 12 (2.6.32.11-99.fc12.i686.PAE) is usually connected to a big screen (1920x1200).
Now each time I boot, X becomes unresponsive shortly before or after login for a couple of minutes, and then goes back to normal. This happens both with and without connection to the big screen.
The error messages associated to this seem to be like this, my /var/log/Xorg.0.log is cluttered with them :
Code:
I normally start my computer in the morning, walk off for some tea, and come back when X is functioning, but when I'm in a hurry it's pretty, or very, annoying ... drinking tea / coffee to wait for a computer to start is something people did in the 90s, it shouldn't be default behaviour in 2010 ...

Xorg - Screen Blanking after 10 minutes. Backlight level lower upon return. This is my .xinitrc file:
Code:
#!/bin/sh
#
#~/.xinitrx
setxkbmap "se"
xmodmap -e "remove lock = Caps_Lock"
xmodmap ~/.xmod
xrdb ~/.Xdefaults
xset r rate 200 25 .....
Code:
LIBGL_ALWAYS_INDIRECT=1
INTEL_BATCH=1
pcmanfm --desktop &
compiz --use-root-window --indirect-rendering ccp
After 10 minutes in idle state (watching a video in vlc or in flash counts as idle time too) the screen blanks. As I mentioned in the title, the backlight level is lower when screen turns back on. This is a new feature of the problem, and might be related to a recent upgrade of xorg. Where is the configuration file that handles the screensaver? And why is it even enabled by default?

I own a rather large website/forum devoted to Scuba utilizing vBulletin. The problem is that its become INCREDIBLY slow as of late. I have three Ubuntu web servers under a single Ubuntu load balancer and they draw from a CentOS 5 DB server running MYSQL. Here are my concerns:
-I am thinking that they are all 32 bit rather than 64 bit.
-I am thinking that the problem is an IO issue.

My macbook is backed up using timemachine on a samba drive. I used this hack for months [URL]his tuto is based on Netatalk, but works perfectly with Samba (or used to), as described in many others blogs.A couple of days ago, I had a strange message from timemachine, like the backup should be reconstructed to improve the security. The sparsebundle has been deleted, and timemachine try to create a new one now. This step failsI tried to create manually a new sparsebundle, using the tuto. It does not work.I have a backup of the sparsebundle ... I can navigate into it ("enter timemachine"), but I cannot backup anymore.

I am running Ubuntu 10.10 and have 5 shares that I have setup for Samba (assume names of share1, ..., share5). I find that shares(2,3,4) are accessible from my MS Windows system, but the share1 and share5 are listed but Windows gives an error accessing them that I may not have permissions.I have reviewed the sharesve the same owner, group, and permissions.Is this a known Samba bug or configuration issue? I have gone through the smb.conf file multiple times as well as examining the directories and do not see what the issue might be.

I am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

I am having a problem with the server that I use to host my personal site. The load average quite often spikes to exceed 1.00 for the 1 and 5 minute intervals, and the 15 minute interval gets above .5. This occurs while the server is idle, serving very few or no requests and with the CPU 99% idle with <1% IOWAIT usage. I have checked top and vmstat, but neither one provides any useful info. Top continues to say the CPU is 99% idle, and vmstat says that there are 0 runnable and 0 blocking tasks. Occasionally, vmstat will say that there is 1 runnable task, but this doesn't even coincide with the load average spikes. I have already searched for other solutions to this problem, but everything I have seen says to use top and/or vmstat, but those aren't showing anything out of the ordinary. Can anyone recommend anything else I might do?
My server has a Pentium 4 HT 3gHz processor, 2GB RAM, and runs Kubuntu 10.10. (The reason it runs Kubuntu instead of Ubuntu Server is that it needs an X environment so that the Nvidia driver can initialize and put its graphics card into a power saving mode.)

When I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.
The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.
What is causing this?

I can't seem to figure this out. I've got a DOS disc that loads up a network share (my Samba server running Fedora 10) - connects to the share, runs ghost.exe from there. Everything runs perfect for about 2 minutes, then my thoroughput drops to 0. Sometimes, after about 40 seconds, it'll resume imaging. Most of the time, after about 40 seconds, Ghost gives me an error stating 'not enough free space on the destination disc' - This is a raid 5 3TB array that I'm ghosting a 6.0Gb HDD to!
lanman auth = yes and client lanman auth = yes are already set up - I can connect fine, but it's almost like Samba hiccups and drops my connection!

When using Amarok in Kubuntu 10.10, the player will shut down after no specific reason. Sometimes if saving a playlist and sometimes when the player changes from one track to another. I presume this is a bug but sadly i do not have regular access to the internet so my system is sometimes up to a month old but no more.
Has anyone experienced similar performance when using Amarok with Kubuntu?

I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

Using 11.2 on self-built pc with AMD 9950 on Asus M3n78 Pro mobo. Boot drive is sata, with an external ntfs 1.5 tb USB/firewire/externalSATA connection (using USB at the moment.) nVidia 9800 GT video card (8300 gt on mobo.)It takes literally hours to boot up and more hours to shutdown this system.e point I am ready to hit hardware reset to continue. This is the 5th cycle with the same problem recurring each time, except sometimes boot occurs in a normal amount of time, but shutdown/reboot always takes hours.

I don't shutdown my OS really often and sometimes the driver of my soundcard seems to crash so I need to restart it. I use the command "rcalsasound restart" which works well or "/etc/init.d/alsasound restart" but I lose the volume control during the operation. Moreover, I have a dell laptop with sound keys and naturally it doesn't work to. Do you know how to restart the volume control applet? And I'd like to know why these commands don't start also the volume control (I'd like to know a bit more how it works).

I've installed the latest cvs for ubuntu 10/04 and read a couple of how to on the web. I have environment set for CVSROOT, EDIT and CVSEDIT. It made me a ~/cvs/CVSROOT and I ran" cvs import mon Ian_C START" in my ~/cstuff directory and that has created ~/cvs/mon with my main.c file. These tutorials do not tell me which main.c file I should edit or how to edit. Should I edit ~/cvs/mon/main.c or ~/cstuff/main.c, should I just gedit it then do a few cvs commands to generate the diffs or whatever?

i recently decided to try and run a couple of games through wine, however trying to install two of them through wine, after putting in the second cd in the installer, the system will not recognise/mount the cd at all in the filesystem. it will instantly recognise the cd after i quit the installer for both of the games, so i guess that running the wine setup is interfering with ubuntu's ability to read or mount a cd. since it has happened on two separate occasions and has worked on windows, there must be something happening on my system that is preventing it. so my question is has anybody else experienced this or think that they know what might be causing the problems?

In a small network (with <5 PCs) what is the best way to manage users and groups? When I create a new user, Ubuntu automatically assigned a UID unless I specify otherwise. If I were to mount shared drives between PCs (or between a client machine and a server) I'm wondering how it handles different UIDs/GIDs associated with files (usernames almost always match across system but UIDs/GIDs do not)? Or is the best solution to just assign matching UID and GID on every machine when they are created? Or is this just magically handled via the matching usernames? I know there are heavier options but this has come up a number of times in small setups 2-5 machines at most.

I'm looking for advice on a good backup solution. I have a couple Ubuntu machines running at home, and I'd like them to backup to a NAS, which supports CIFS and NFS. Rsync might work, but I don't want to have to write a script myself, or figure out how to accomplish a staggered history of backups. The default "simple backup" sbackup doesn't work for me. I've not been able to unroll those gigantic .tgz files it makes. The restore GUI doesn't seem to work at all; it claims it can't find any backups.
My confidence is shot. I tried Back in Time. I set the GUI control panel to backup every day. It didn't back up every day. Maybe I'm getting it wrong. But, my confidence is shot. I looked at Amanda and Bacula. Both seem to require that your backup server run special software; I don't want to hack into my NAS to do that. Both also seem to require 10 hours of study to figure out just how to install them.
