The 2 machines are a bit different, so

1) kernel 2.2.18 1 user (apart from root), login via terminal, rlogin,
ssh, X (like rlogin x, xterm)
right now who reports me on pts/1,3,4,5,6; ls /dev/pts gives the same -
1,3,4,5,6

2) kernel 2.4.2 users can rlogin, ssh, X into the host, same - who's
report agrees with ls /dev/pts.

Not sure what this means, sorry, only can tell that I can ssh to it from
outside the firewall, which IS a masq'ing server, I assume.

See above

Same

What does this mean?

Thanks Guennadi
