Ubuntu Servers :: Server Load On Clean Install And "free -m" Results

Mar 31, 2011

Recently I've gotten myself a VPS and tried to begin small - 512 MB Memory, 10gb HD.

Ubuntu 10.04 got installed on it and decided to make a user for myself besides root, installed a lamp enviroment and let that extra user own /var/www, since im the only one developing on the vps.

Then I ran the free -m command... shockingly it had 450 mb in use, and around 40-60 mb free (varieing around a bit).

Is this normal? If so - why are company's selling vps'es with 256 mb ram... thats just ... not logical ;x

Ran the free -m command again after letting it idle for about 5 mins. Same results.

the 'top' command tells me that the cpu is boring itself with around 1% use.. not a suprise with only lamp on it and 0 visitors yet =P

So ... why does ubuntu take up nearly all my precious memory? should I upgrade to 1 GB of memory to be completely safe I dont run out of resources or is something else going on here?

Discovered I was miss-reading the free -m command. To avoid confusion in the future I install htop, which is configurable to show a... nicer view of what's being used by what. Turns out I was using 50 mb.. >.>

Fedora Installation :: Can't Seem To Get OS To Load For Clean Install

Apr 8, 2010

So, I currently have Ubuntu on my laptop and would like to install F12 instead.I burned a copy of the F12 .iso and set my BIOS to boot from CDROM drive, but Ubuntu continues to load and I can't seem to get the OS to load for a clean install (from the .iso, even after extraction).Unfortunatly, the BIOS will not let me boot from USB otherwise I would try that.Any ideas on what might get this off the ground?

OpenSUSE Install :: Clean 11.2 Install Afterwards Hang On Load?

Jun 6, 2010

Okay I did a clean network install on 11.2 on my test machine.Old gateway box but it had min requirements. It will load completely into failsafe mode but will not complete a normal boot option.The default Green background images comes up and the cursor comes up, but I let it sit for 30 minutes and nothing. I did a hard reboot, still hung on cursor and green back ground. Booted again but this time choose failsafe, boot up completely. Am I doing something wrong? I have installed many many version of Linux in the past never had a problem like.

Ubuntu Installation :: 9.10 Upgrade Needs More Space / App That Results From Sudo Apt-get Clean?

Jan 27, 2011

forgive me for raising a common problem again, but I cannot find a fix in the other threads.
I am trying to catch up on upgrades. Step 1 is to get up to 9.10 from 9.04
Doing so however I am being told I don't have enough disk space
I present have my 35-odd GB HDD partitioned:
6GB for Ubuntu
28 for Data
and 1. or so for swap

evidently I underestimated my Ubuntu partition.

what can I do now?

I have run Computer Janitor (is that the application that results from Sudo apt-get clean? I did that but couldn't figure out how to "clean"?)

I have Gparted installed but I don't see how to use the Move/Resize option.

Ubuntu Servers :: Clean Install Fails To Reboot

May 17, 2010

I'm installing 10.4 x64 on a Dell PowerEdge R610 RAID 1 and the install goes fine until I have to reboot the finish it. On reboot after about a minute it gives the error

Code:
Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline/
-check rootdelay= (did the system wait long enough?)
-check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/mysql1-root does not exist. Dropping to shell!

what to do and my co-worker who knows a little more about Linux can't get it to let him check any of the above common problems.

We're tried letting GRUB manually configure itself at the end og the install before we reboot and we've also pointed it to /dev/sba partition which is what should be the boot partition.

EDIT: in the code tag it's ALERT! /dev/mapper/mysql(one)-root.... the L and 1 look the same

Ubuntu Servers :: After Clean Install - Network Cards Not Installed?

Feb 10, 2010

I have a Proliant 7000 with 4 interfaces across 2 cards - 3 intel 10/100Tx and 1 intel 100FX. During install it detected the 3 tx interfaces - but couldnt see the network - post install the network devices were no longer there, their devices missing from /dev/.

Neither google nor a forum search have been particularly edifying, is this a known issue with any cards? If so is there a known fix? ifconfig gives me information for loopback only as expected.

Ubuntu Servers :: Bash In 10.04 Server - Every Empty Line In The Script Results In "command Not Found"

Bash acts weird in 10.04 server. Whenever I try to run .sh scripts, every empty line in the script results in "command not found".

Ubuntu Installation :: Server 9.10 - Can't Log In To The Clean Install - What's Username

Dec 30, 2010

I have installed Ubuntu Server three times now. It "NEVER" asks for a "USERNAME". I can't log in to the clean install. Guess what? I never entered a username, so I don't know what it is. I have never logged in. Don't ask me to go to /etc/, I can't log in. It is NOT a video proplem, Ubunto Server is command line OS.

Login incorrect: [system-name] login: Login time out after 60 seconds.

I'm asked to enter a network system name during install. I'm asked for a password, then repeat it during install. but never asks for a "UserName" during install. So, what is it? root? ubuntu? default? Nope, I've tried many many many of them, even admin, nothing works.

Server :: Use System Monitor Via A VNC Connection The Free Disk Space Value Is 20GB Free On The Same Volume

May 18, 2011

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

Ubuntu :: SSH Server Only Wants To Work On The Very First Boot Of A Clean Install - No Route To Host Error

Apr 22, 2011

Ok so I just installed Ubuntu 10.10 Server Edition. On the very first boot, everything seems to run perfectly. I can SSH into it from any remote computer with no problems. However, the installation of certain things calls for a system reboot, which 2 days ago never would have been a problem. But now for some reason, the SSH server only wants to work on the very first boot of a clean install. After I reboot it, I get the ssh: connect to host 192.168.0.180 port 22: No route to host error. The absurd part is sshd is running! I've even tried restarting sshd, restarting the server, and using both 64 and 32 bit installs. The only way I can get anything to connect to it is by using ssh localhost. It won't even let me connect using the IP on the local machine!

Ubuntu Servers :: Web Server Time Freeze And Weird Load Avg Data?

Aug 23, 2010

I am completely stumped. Found my web server (lighttpd) unresponsive this morning and had to hard cycle it. After some cleaning up, all was happy. However, after about an hour of handling a decent amount of web traffic, time freezes as far as the web server is concerned. I've got an hour of access.log data with the following date: [23/Aug/2010:20:42:58 -0500]

It never changes. The load average now reads 0.00 0.00 0.00 (which is totally inaccurate). And I am not able to successfully log in remotely. I have taken the server down 3 or 4 times today and after an hour or so of functioning normally, this is what happens. Additionally, the local time is now off by 30 minutes.Trying to force with ntpdate does nothing (or, at the very least, sets it to the same incorrect time)

Ubuntu Servers :: Shutdown Command Results In Lock Up

May 2, 2011

When I shutdown my server it seems to lock up. I use ssh for a headless unit and I can reboot fine, but I told it to shutdown and disconnected me and stopped logging (as far as I can tell) and then nothing. The lights stayed on and I had to press the power button. Is there a way to keep the logger running or to look someplace other then messages. I'm not great with logs.

Ubuntu Servers :: Entering Correct Password For Sudo Results In Segfault After 2 Attempts

Feb 2, 2011

I cannot sudo nor log into a second ssh session on my Ubuntu 10.10 server edition headless setup. Entering an incorrect password works as expected but the correct password gives errors, and on the second attempt a segfault. I recently changed my password as the old one was about to expire, that was 3 days ago, I can't find evidence that I have sudo'ed or logged in a second session since, I have been logged into it via ssh throughout all of it and I am still currently logged in. What should I do to correct this problem? I'm worried that by turning it off I will lose all access. Is the only option using a live cd to change the password?

Ubuntu Servers :: Run Fsck If Last Shutdown Wasn't Clean?

Jun 13, 2010

I have a file server that has a raid array with a jfs file system attached. Whenever there is a power cut (quite frequently in our house), and the server is not shutdown cleanly, then the raid array is not automatically mounted since ubuntu doesn't know if the journal is clean. I have to then manually run fsck and remount the partition by hand which is a bit annoying. Basically, does anybody know if fsck can be setto run if a non-clean shutdown has been detected, or failing that, on every boot?
