How to change the MAC address of your machine-Linux Based Systems

In linux, you can change the hardware (MAC) address of your machine.This is how it is done.


# ifconfig eth0 down
# ifconfig eth0 hw ether 00:80:48:BA:d1:20
# ifconfig eth0 up
# ifconfig eth0 |grep HWaddr

Note: You just cant give anything as mac address it should be in the format xx:xx:xx:xx:xx:xx,

Well why do you need to change a Mac address? If you want to fool some body who is using a database to store the service provided to you via mac address hope this explains it all

Change Hostname Permanently

Want to change your server’s hostname?

There are a few places you should check.

Edit the name in /etc/hosts

Edit /etc/sysconfig/network. It’ll contain something like this:

NETWORKING=yes
HOSTNAME=”yourserver.com”
Edit /etc/hostname. e.g. echo “yourserver.com” > /etc/hostname

Reboot your server, or just run: “hostname –file /etc/hostname” i.e. set the host name based on the name in the /etc/hostname file.

Applications that were running before you changed the hostname will probably not reflect the new host name until after an application (or server) restart.

Of course the server’s hostname can be anything you want it to be. It doesn’t mean anything to external servers. They will rely on public DNS information.
