Fedora 7 telnet-server problem

Ok, I just solved my own problem. On a whim, I compared the
"/etc/hosts" file on the two machines that had a working
telnet-server, and on the one that didn't work. I noticed that on
the bad server, the FQDN was not in the first line. The first line read:
127.0.0.1 localhost.localdomain localhost SuperNova
Wheras on the other two, the first line was similar to the following:
127.0.0.1 Commander.mydomain.com Commander localhost.localdomain localhost
When I changed the bad server's "/etc/hosts" file's first line to read:
127.0.0.1 SuperNova.mydomain.com SuperNova localhost.localdomain localhost
then telnet worked again, just like the other two machines! Frankly,
I am amazed that I stumbled across this. I would never have thought
that the "/etc/hosts" file would affect an incoming telnet session on
a machine. I wonder why this happens? I just lost a couple of hours
trying to figure this out.
I am having an issue with the telnet-server for Fedora 7. I set up 3
machines with F7 in the last week, and followed the same procedure
with all of them. I installed telnet-server with the following procedure:
yum install telnet-server
edited the appropriate xinetd.d file to turn on telnet
On the first two machines, telnet worked fine. On the last install I
did, I encountered a problem with the telnet-server. When I try to
telnet into this server, I get the following message:
Connected to 192.168.2.72.
Escape character is '^]'.
getaddrinfo: localhost: Success
Name or service not known: Illegal seek
Connection closed by foreign host.
I have never seen this error before. It happens when I try to telnet
to the machine from itself, as well. What could cause this? I can't
seem to find much information about this problem.
I do know about ssh and use that as well (ssh works on this machine),
but I do need to have telnet working too.
