From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) Description of problem: When I installed the new openssh rpm I could not connect to a remote machine running 2.1 but openssh 2.1 will connect to a machine running 2.5.2 How reproducible: Always Steps to Reproduce: 1.Install rpm 2.add identity.pub localhost to remote host 3.rsync to the remote machine and it requires a password Actual Results: Asks for my password. How can you do a back up at night if you need to add a password Expected Results: To connect to the server without sending a password Additional info: This seems to be the problem on the openssh that shipped with Redhat 7.0. The update to openssh.2.1 fixed this problem but the newest openssh.2.5 has the same problem
Identity.pub is only used for SSH1. It's not the default anymore. You could try forcing it with ssh -o Protocol=1, and see what happens. Else you could try creating SSH2 keys. In any case, if this does not solve the problem, ssh -v -v -v and sshd -d -d -d output is needed.
Neither openssh2.5 nor 2.1 is supported anymore. And you shouldn't use protocol 1 anyway as it's vulnerable to the man in the middle attack.
