Thanks for the clarification.  Apparently my Kerberos telnet server
doesn't bind to IPv6.  Now trying a ssh session, which apparently
does, it doesn't show up in /proc/net/tcp but does in /proc/net/tcp6.

BTW, is it expected behavior that when I cat /proc/net/tcp, the
local_address and rem_address are byte swapped on a little endian
system (this just noticed on a 2.6.15.4 kernel)?  They're not
byte swapped on a big endian system (2.6.15-rc5 kernel).  And
the port number portion of the local_address and rem_address isn't
byte swapped on the little endian system, but the IP address portion
is.
