I just noticed that if I do:
(in that xterm now...)
sudo sessreg -a -l ttyp9 -h myhost myname
... then in another xterm, `slogin' or `telnet' somewhere off-site,
and do `finger myname@myhost'. The output from `cfingerd' here shows
"ty" under the TTY heading. `talk myname@mhost' works properly.
sudo sessreg -d -l ttyp9 -h myhost myname
sudo sessreg -d -l p9 -h myhost myname
... and now that finger query shows "p9", but the talk request fails.
I guess we should fix this.
