Geez, Alexey, why would anyone try to "fool" someone with this? My log itself shows TELNET. I'd bet Mark's does as well.

Well not with that IP.. <g>. I can get a good session with this command:
# tcpdump -s 2048 -nlvvvX tcp and host 71.30.81.243
That's Mark's IP there, not what you posted.

I will try, but I wonder if FD will even let us connect on Mark's side since he has a PW for my system?
