I'm running FreeBSD 2.0a with the security distribution installed, and it 
seems that telnetd is not correctly resolving hostnames on incoming 
connections. If I telnet in to the machine from anywhere except localhost,
the address it records (to utmp,wtmp,etc..) is the numerical host address
rather than the hostname, even when nslookup on the same machine correctly
returns the hostname. This happens only with telnet connections; rlogin
connections resolve the hostname properly. Has anyone seen this? I thought
I'd ask before poking at the source.
