[ILUG-BOM] changing hostname

I tried to change my hostname from the file /etc/hosts but the hostname remained the same.Now I found this /etc/sysconfig/network file which had my hostname.I changed the hostname and now my hostname is changed. Is this the correct procedure to change the hostname ?

Now when I run startx I seem to get following message: hostname lookup failure I can't read all the messages as the x server now displays the gray screen. I can work normally with the net and mail.

How can I redirect the messeges of x server? I tried using startx >> ~/temp but nothing is written to the temp file.
