Hi All,

 

I need to check service statuses of linux from Nagios Monitoring tool.

 

Is there any plugin to check service statuses of linux?

 

I wrote one shell script for this:

I know Ubuntu is the simplest and easiest distro, and I have used the live cd and played with the full installed version that my grandfather installed on his PC, so I know I can operate it. But, I refuse to just use it, I am fine with it being for everyone but I want to learn how to use the terminal and really play with it. I admit, I am not an expert, but I am eager to learn how to use Linux effectively.

 

My first question is: I know Ubuntu is open-source, but where is it's source? I hear people speak about how you can code it and all that but what do they mean?

Hi,

 

Top site by the way, seen a few guides that'll I'll be reading later.

 

But my first problem is actually connecting to my linux server!!

 

I've had it changed from win 2003 (which I used to use remote desktop connection) to linux for various reasons but now I just don't know how to get on it.

 

Is there a programme I need or is it done through a web page? Any help would be appreciated.

 

Thanks,

 

QC.

I've used putty and I'm on. No idea what I'm doing now, time for some serious reading!

I think I've done something wrong?

So, over the past while i have been working on getting a new kernel working on my system. The problem i was having is that the newer kernels i use are not loading the sata modules properly from the initrd images.

 

When trying to fix this i would run into the scnenario whereas, i reboot using the new kernel and if it kernel panics, i then have to file a ticket with my hosting provider to reboot the system and select the old kernel.

 

I have now found 2 ways around this that might be useful for anyone who does a lot of kernel testing.

 

1.) Booting once-only - (same as lilo -R)

 

In reference to [/url][url=http://www.gnu.org/software/grub/manual/gr...g-once_002donly]http://www.gnu.org/software/grub/manual/gr...g-once_002donly

 

in grub.conf, add the following line to the beginning.

 

default saved

 

If for example your grub.conf looks like the one i have below. This boots into the 2.6.20-1.2944 by default.

The worst thing that happened was that Yggdrasil Linux died. But the Earth kept spinning..." Read the rest of the editorial at TheJemReport.

Quote:This article details how to make Ubuntu use the ROX Desktop without using ROX Session. "Can we get rid of ROX-Session? It should be possible to integrate ROX with your existing session manager. In this experiment, I configure a fresh Ubuntu installation to run ROX, without using ROX-Session."

I decided I wanted to test Feisty this easter, even though it's a Beta.

 

A quick "update-manager -d" in terminal, and a button click later, I was on my way from 6.10-7.04 (Edgy-Feisty)

 

Things were OK until Friday the 13th, when It was time for a Kernel Upgrade. I quickly figured out that something was not right with the new kernel (2.6.20-14), since it wouldn't boot. The boot splash would come up, but grind to a halt early on. Shortly after I would get the following:

 

BusyBox v1.1.3 (Debian 1:1.1.3-2ubuntu3) Built-in shell (ash)

Enter 'help' for a list of built-in commands

 

/bin/sh: can't access tty; job control turned off

(initramfs)

 

As I was looking into this problem, I found out that this was a common problem.

 

To get around this, I booted with an older Kernel (2.6.20-13), and things worked almost as before, so I started looking into this too. A little reading went by, and these following "problems" are common.

 

The first thing I discovered was that windows were missing the _, the square and the X up in the right corner. This is caused by the fact that metacity is not starting automatically any more. I solved this, for the time being, by adding it under Sessions, and now it works fine. Windows don't end up on top of my panels. As far as I have understood, this problem pops up for users that automatically saves the session.

 

Another little problem I had was that DVD movies wouldn't play anymore. This was also an easy little fix, simply reinstall libdvdcss2. For some reason libdvdcss2 had been deactivated during the upgrade the 13th.

 

As for now, this is all I have, but I'll keep on testing things.

 

I will come back with a little more info on the Kernel problems when things indicate that this problem is solved.
