Here is where my lack of professional networking experience cases me a bit
I don't know what my host name is....I know I am a part of the sd.cox.net
domain, but do I need to call my ISP to get my host name?
When I was using windows, I didn't need it because I just made up a NetBIOS
name which was whatever I wanted it to be.
I don't have a file /etc/hostname, and under /etc/hosts all I have is:
127.0.0.1 localhost.localdomain localhost
I don't have any trouble running KDE, sending mail from KDE with KMail,
running other processes, etc, but when it comes to sending mail from the
command line with sendmail I constantly get MAILER-DAEMON letters to root
saying I can't send mail because "xxx.sd.cox.net" is not a legitimate fully
qualified domain name, where "xxx" is whatever name I chose for my host.
Maybe I need to call the ISP.
