I posted this question on an internal forum sometime back (having somewhat the
same concerns). The answer seems to be: BSD-style unixes (unices?) have a
place in the utmp entry for the hostname of the originator of a remote session.
Sys5-style unices don't. The suggestions I got were: (a) hack up login/telnet/
rlogin etc. to put hostname info in the utmp entries or (b) do an ugly search
of utmp entries, inetd logs, etc to match up entries to figure out who the
originator was. Needless to say, it is not an easy task...

Can someone else confirm this for me?
