[TriLUG] sshd

[Nathan Conrad]

Hi all,

I've recently installed Debian on my older computers, a 175 MHz Pentium
(named Nort, now with 24 MB of RAM (although it was installed with 12)). I
set it to have a static IP address: 192.168.0.7. The networking works, it
can ping to 192.168.0.2 (my other computer, Max) quite nicely. The problem
is that when I connect to it from a remote computer it takes about 12
seconds for it to ask me for my password. Nort can can can connect to Max
without this delay. 

Why would this be happening? Slow computer? Misconfigured sshd? I am
impatient?

Both computers run Debian. Max is a Macintosh G4 400.
