Since phoenix1 and phoenix2 can ping phoenixl by name (bad policy to
use the difference between "1" and "l" as the only difference between
names) I guess you have a router which runs a DNS and knows that phoenixl
has IP 192.168.1.105. I assume the router knows about phoenix1 and
phoenix2, too. Can phoenix1 ping phoenix2 by name? If so, I don't know
why the router refuses to tell phoenixl the IP's of phoenix1 and phoenix2.
Maybe someone else can help. But another way of supplying phoenixl with
the relationship between IP and name is to add appropriate lines in
/etc/hosts for phoenix1 and phoenix2.
Speaking of /etc/hosts, you may be better off removing the line
192.168.1.105 phoenixl
and replacing the first line
127.0.0.1 localhost.localdomain localhost lo
with
127.0.0.1 localhost.localdomain localhost phoenix1
so that your computer knows localhost is the same as phoenixl. That way
it won't matter to phoenixl what IP it gets assigned, and "hostname -f",
"hostname -i", ... may stop complaining about "Host name lookup failure".
