Under Ultrix 2.0, users cannot telnet into our microvax from a host
with a long name.  The process telnetd.gw core dumps.  From adb I can
see that the source hostname kepler.yerkes.uchicago.edu was strcpy()d
into a 24 byte buffer and hence clobbered the next variable.

Strangely enough, editing /etc/hosts to call the remote host simply
"kepler" doesn't work either.  Telnetd.gw doesn't core dump, but it
does die with a signal after printing its hostname but before
"login:" is printed.  I don't understand this at all!

We bought updates, but 2.2 hasn't come yet, and I don't know if a new
release of decnet/ultrix comes along with it.  Does anyone know if
this bug will be fixed?
