Wow! No password prompt, yet you're out of methods to try. More and more this sounds like it's not an SSH issue at all. So, several things to try. Please report on all of them ... * Now that iptables is stopped, can you telnet? * Can you telnet (or ssh) as a different user? e.g: ssh [username]@[machine.address] * Can the user you're trying to ssh/telnet in as log in on the * console of this RH8 machine? * What happens when you mv the .ssh directory out of the way (to * something like .ssh-old) and try to log in? It sounds like your keys may have changed, or password data changed, or machine OS installation changed, or user data become corrupted somehow. Frankly, it sounds like ssh is behaving properly and you just have to find the right key for that particular lock. In any case, it should not run out of methods to try without offering a password as the method to try. I suppose this can be disabled--in that config file I didn't read--but the above tests should help identify if it's really ssh, or something else. John J.
