Both servers run openssh 4.1p1(that comes with FC4).
my steps:
Client ssh box:
$ ssh-keygen -t rsa1
It will generate identity.pub and identity.
Server ssh box:
Put the content of the identity.pub to authorized_keys (add it to the end of
this file) that can be found in the user's dir you want to login under, e.g.
for root it should be /root/.ssh/authorized_keys
That's all.
After this I could connect to the server ssh box under root w/ no passwd (I
entered passphrase empty) using ssh1 protocol:
[vitaliy 06:51:48 PM]$ ssh -1 root at X.X.X.X
Last login: Sat Sep 10 22:25:33 2005 from Y.Y.Y.Y
[root at blabla ~]#
But again it's for openssh that support both ssh1/2.
What software do you run on your boxes?
Maybe it's actual to use ssh2 as ssh1 is not secure.
Best regards.
