To use this plugin you need to have varnishstat installed which is installed by default when you install varnish.

Perl is also required for this plugin. If you don’t have Perl installed you can install in by running the command below
sudo apt-get install perl
or
sudo yum install perl

Now you can download the file above and extract it:
wget <a href="http://www.toms-blog.com/wp-content/uploads/2013/07/check_varnish-v1.0.tar.gz">http://www.toms-blog.com/wp-content/uploads/2013/07/check_varnish-v1.0.tar.gz</a>

Creating Custom Built Debian 6 (Squeeze)

by

There is a well documented official way to create standard Debian CDs. However, sometimes it is nice to have a CD or DVD which just contains a subset of Debian Packages to fit personal needs. The following script is made for creation of such a CD image. By default, it fetches all packages installed on the local computer from the configured apt package sources.

Download the Shell Script from here-

make-debian-cd

Bevor running the script make sure all packages installed on your system are available for apt-get. If in doubt update the package repository and clear the apt cache by running

# apt-get update && apt-get upgrade -y && apt-get clean

Call the script with the -h flag to get all avaliable options:

$ ./make-debian-cd.sh -h

Usage: make-debian-cd.sh [Options]

Options:

-i Image name [debian-squeeze-20110528]
-c CD-Rom mount point [/media/cdrom0]
-s Selection [localhost]
-v Installer version [current]
-m Install dir medium [network]
-d Debian mirror [http://ftp.de.debian.org/debian]
-e Path to extra packages [.]
-a List of additional packages (Comma separated)
-O Don't use override files
-I Don't include install dir
-M Don't create CD image
-V Verify CD image size before making the image

Selection may be a text file generated by "dpkg –get-selections".

Installing MondoArchive in Debian 6

by

MondoArchive is an excellent backup tool found in Linux. However, the installation process is not obviously clear in debain- it lacks of a simple clue to let you know how to install in the easiest way in debian by using 'apt-get'.

All you need is to add this simple repository to add in your /etc/apt/sources.list file-

deb ftp://ftp.mondorescue.org/debian 6.0 contrib

Then hit-

apt-get update
apt-get install mondo

There you go… it is installed 🙂
