Answer 1

You may need to do several things to change the hostname (some or all of the below depending...)

Edit /etc/sysconfig/network and see if there is a HOSTNAME= directive, change as appropriate e.g.

HOSTNAME=ex1.example.com

Issue a hostname command as root e.g.

hostname ex1.example.com 

Then restart networking

/etc/init.d/network restart

You should also take a look at /etc/hosts and see if anything there needs tweaking.
