I am working from Linux System Administration (LSA) Adelstein &
Lubanovic, O'Reilly, 2007 (p. 14). LSA is a detailed guide to building
an internet server on Debian Linux ("sarge"), which is what I am
running.
I added the second line (following LSA) because I am building an
internet server with a static IP address, and there needs to be a line
in /etc/hosts that maps the host and the FQDN to the static IP
address.

According to LSA, if I execute
echo myserver.mydomain.org > /etc/hostname
and then
/bin/hostname –F /etc/hostname
then /bin/hostname should print "myserver" (the hostname w/o the
domain name)
What do you get on your system?
Thanks for helping a neophyte, Twister.
