I need to change the hostname of a server with RHEL 5.6.
Can someone provide a reliable and supported procedure to do that?
Thank you.

Forgive me if this seems rude but have you looked into the manpages of 'hostname'. Yes, there are some people here who have all the answers you need but the point of linux is to look things up for yourself and unless you are willing to do that there would always be this peculair gap in your knowledege that would make you impossible to understand even the bare bsics.

The command hostname will change it but not for a permanent change and you may have to restart network to get it to work also.

This should work. http://www.ducea.com/2006/08/07/how-...-linux-system/

@jefro - yes sir I understand that hostname will _not_ change the name permanently. But the reading of the man pages will give the OP a lot of information as to how things work It was supposed to be the starting point for the OP - atleast that was what my intention was.
I apologise if there was any miscommunication.

honeybadger,

I wasn't picking on you. Just wanted to say that the command hostname is sort of what the OP asked but not really what one would use in real life. It could be a new person just asking a homework question. Dunno.

You may not have known that teckk posted a link to hostname.

I did have to look up the range of a honey badger and also the urban dictionary meaning. Odd that a fierce animal is also a term for one that doesn't care.

also this is red hat
so the VERY first stop the OP should make with a question on how to do something should be the knowledge base
