Setup: one cygwin box, one Fedora FC2 box, one Redhat 7.3 box. Starting
from cygwin, I can use ssh-agent to log in to either Linux box without being
asked for a password. I assume this means I've correctly copied around the
authorized_keys and that permissions are correct.
The problem is that I'm asked for the password when ssh-ing the second time;
ssh machine1 doesn't ask for a password, but an ssh from machine1 to
machine1 (between the two linux boxes) does ask for a password.
Suggestions?
