Hostname in DHCP

2011-06-23T13:46:00.000+01:00

I've just noticed that a new CentOS 5.5 server I'm building did not register the hostname within a Windows DHCP management console. If this ever happens to you do the following...

Try entering the following in /etc/sysconfig/network

DHCP_HOSTNAME="RH73hostname"

Remember to restart the network service...

service network restart

Network Monitoring

2011-06-23T10:07:00.001+01:00

As the networks you manage grow the importance of robust, reliable and easy to use network monitor software is crucial. If you type in the word "open source network monitoring software" into Google you will be presented with a raft of recommendations.... scroll down until you come across "Zabbix"!

I've used both an appliance "VMware/Virtual Box" application but only for BETA testing and the full stable version.

Installing the full stable version on to a CentOS 5.x server was straight forward enough, thanks to a little script provided by BB'sBlog. It works every time with out fail.

I've update the script to download version 1.8.5 - click here to download

We all know what a great resource Youtube can be, the trick is to find reliable and clear video tutorials. I discovered "thejonasnet" channel when setting up my first CentOS 5.5 server and integrating that with a Windows domain.

These are great tutorials and work every time... thanks Jonas

Windows to Linux... you know it's the right thing to do!
I little while back I started a project aimed at reducing the dependency and cost of using Windows and Office. One little gem is DavMail, which will allow you to use Thunderbird + Lightning to access an Exchange Server.

Installing Webmin on CentOS 5.X

Installing Webmin on CentOS 5.X
On every installation of CentOS I've done, Matt's Blog on how to install Webmin, allowing you to manage your server using a web interface has been right next to me. This is so simple and works every time.... Thanks Matt

Here is an updated version of the code...

This will install some dependencies.
yum -y install perl-Net-SSLeay

Install the system:
cd /usr/src

wget http://sourceforge.net/projects/webadmin/files/webmin/1.550/webmin-1.550-1.noarch.rpm/download

rpm -i webmin-1.550-1.noarch.rpm
