IP Address and name change on Asterisk

Hi, new to Asterisk so bear with me!

I have cloned my server and need to rename and re IP it.

I would like to know the following:

How do I rename my asterisk server?
How do I change the IP address?
Do I need the MAC address in the ifcfg-eth0 file and if so how can I get it?

Then I need to connect the 2 boxes together using IAX.

Thanks in advance

Ok, I have changed IP and name now.

Just need to do the iax.conf to get them talking.

I have 2 servers -

pbx on and pbx1 on

please can someone help with the iax.conf file?

you have very information in the internet, or read the reference book…just search;
