Installation of Munin and Munin-Node

Tue, 11/04/2008 - 09:45 — manoj

Munin is network monitoring tool for servers. It uses RRDTool, an open source used to generate graphics and logging server activities.

I am installing and configuring munin on centos 5 x86_64 using yum.
1)First of all, we need to add a RPMforge repository.

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

2)Installing yum

yum -y install munin

3)chaning the ownership of munin web docroot to munin, as by default it goes to root.

chown -R munin:munin /var/www/munin/

Learning Bash Scripting

Mon, 09/22/2008 - 17:54 — manoj

I thought of learning bash scripting. I do not know how tough is it gonna be. I have not looked at the whole complicated script at all.
I am gonna begin with a simple bash script.

First I need to locate where my bash interpreter is located.
In my case its located in /usr/local/bin/bash

(manoj@linuxweblog.com)
(~) - which bash
/usr/local/bin/bash
Now I am making a simple bash script that would echo(print a string on my scren)
(manoj@linuxweblog.com)touch first_bash.sh
(manoj@linuxweblog.com)vi first_bash.sh

Password Less SSH LOGIN

Thu, 06/26/2008 - 19:55 — manoj

The main idea behind having a Password Less SSH LOGIN is to be more secure over the internet.
The idea comes from encryption. A set of Public and Private Keys are generated.
The public key stays on the serve rand the private key stays with the user. Only they private key can talk to the public key.

The user needs to upload the public key to the server on
~/.ssh folder and name the file as authorized_keys2

To get the keys working make sure the folder permissons are set correct.

chmod 700 ~/.ssh
chmod 644 ~/.ssh/authrozied_keys2
