I've been having a couple annoying problems with ssh, current version in unstable. First off is, sshd absolutely refuses to use protocol v2, either with the default 2,1 or explicitly setting 2,1 or using ssh -2 to connect. The only way I got it to use v2 was to disable completely v1, which I really shouldn't have to do.
Second is something me and some friends of mine have been banging our heads about for a while; that's that RSA Authentication also just refuses to work. Make the keys with ssh-keygen, move the public key to $HOME/.ssh/authorized_keys on one of the hosts, and from another host use the private key. And nothing happens. Falls through to ask for a password. My config files are the stock ones from the package, now that I've given up on messing with them. Anybody else having problems? Or an idea? Or can confirm that it's just broke? Mike McGuire
