Nagios Error: Could not read object configuration data!

Posted on August 29, 2011 by lorenzo

Some times ago i was experiencing a problem with nagios3 in Debian.

After installing nagios, browsing the nagios web page, i got the following error:

Could not read object configuration data!

Nagios log messages didn’t reported any useful information. So googling around and making some test i discovered that was a permission problem of the nagios cache files. So i solved my problem changing the group of the /var/cache/nagios3/ directory as follow:

chgrp -R apache /var/cache/nagios3/

Previously was set to www-data .

Enjoy!

Script to create fancy ~/.bash_profile and ~/.vimrc for solaris

Posted on June 27, 2011 by lorenzo

How many times creating a new solaris user, you have to set environment variables (PATH, EDITOR, PAGER, PS1, etc)? How many times you have to create a .vimrc file to make vim work in a human manner?

So i wrote an utility script which create for you these two files with some convenient functions. You can download the script Here!

To run the script just give the right permissions and type ./solaris_home.sh

That’s all! If you already have yours .bash_profile and .vimrc, then they’ll backed up with the extention .bak

Try it now and I hope that you’ll be happy!

  1. Get the rpmfusion release:

    su -c “rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm”

  2. Update your packages:

    yum update

  3. 64bit users need to install the following rpms:

    yum install kmod-nvidia xorg-x11-drv-nvidia-libs.i686 xorg-x11-drv-nvidia-libs.x86_64

    32bit users need to install the following rpms instead:

  4. Append the following string to your kernel line in /etc/grub.conf:

    If it doesn’t work try with:

    nouveau.modeset=0

Use SSH as a proxy server

Posted on December 22, 2010 by lorenzo

To use SSH as a proxy server use the following command:

ssh -D 8080 -f -C -q -N lorenzo@www.myserver.com

You will then be prompted for your password, which you should enter. That’s it! Your ssh tunnel is in place!

A quick synopsis of what those switches mean is as follows:

-D 8080 : This basically does a lot of dynamic stuff and makes it behave as a SOCKS server. Of course you could use any non privileged port here (above 1023).

-f : This will fork the process into the background after you type your password.

-C : Turns on compression.

-q : Quiet mode. Since this is just a tunnel we can make it quiet.

-N : Tells it no commands will be sent. (the -f will complain if we don’t specify this).
