What do you mean by "1 key" and "2 keys"? How do you see that?

I mean pub.key (ssh-rsa), it only happens the first time that i access
my Lenny box from outside of my lan; 1 pub.key for the router and 1
pub.key for the Lenny box; it does not happen with Slackware and
OpenBSD boxes.

thanks

yyyyy pts/14 :3.0 16:05 7:46m 0.01s 0.01s -bash

Thanks with best regards,

Has yyyyy a X-session open and maybe two terminal windows in the same or is

I may check another time. Right now on my phone.
It's quite interesting to hide the ip. At least how do I feel now. I also tried the proxychains, it has problem. Those servers only allowed inside connection. I mean inside the firewall seems.

You are right, I use the rdesktop, now it showed me as

lina pts/3 :20.0 11:37 1:08 0.00s 0.00s bash

I have never realized that it has the sesman-Xvnc support.

haha... Thanks with best regards,
