Subject: 'talk' doesn't work!  Did it ever?

On my FreeBSD box at home, the 'talk' command has never worked to talk to 
anyone over TCP/IP, but instead just hangs on "[Checking for invitation 
on callers' machine]".  At first I chalked this up to a PPP 
misconfiguration (since I have dynamic IP assignment, when I was using 
Linux I had to manually change the hostname to "user??.lightside.com" 
every time I logged in or else I would have the same problem).  But now I 
just noticed my experimental FreeBSD Pentium at work, which is 
Ethernetted, has the exact same problem!

The source code to talk looks pretty simple, I should be able to track 
down the problem later today, and see if it's universal or a 
misconfiguration on my part.  Also, my box at home is running 
2.0.5-RELEASE but at work it's running "-current" so if there is a 
problem, it hasn't been fixed yet.  Before I start tearing into the 
source, does anyone have any ideas as to what's wrong?
