[TriLUG] Im stumped by SSH

[Ryan Leathers]

I tried the -vvv as suggested.  Does the output I am seeing indicate
that public key on the server is not being found ? 
A portion of the verbose connection attempt from the client side
follows...

debug1: Host 'rlmsdev1' is known and matches the RSA host key.

debug1: Found key in /root/.ssh/known_hosts:1

debug1: ssh_rsa_verify: signature correct

(section edited)
debug1: send SSH2_MSG_SERVICE_REQUEST

debug1: service_accept: ssh-userauth

debug1: got SSH2_MSG_SERVICE_ACCEPT

debug1: authentications that can continue:
publickey,password,keyboard-interactive

debug3: start over, passed a different list
publickey,password,keyboard-interactive

debug3: preferred publickey,keyboard-interactive,password

debug3: authmethod_lookup publickey

debug3: remaining preferred: keyboard-interactive,password

debug3: authmethod_is_enabled publickey

debug1: next auth method to try is publickey

debug2: userauth_pubkey_agent: no keys at all

debug2: userauth_pubkey_agent: no more keys

debug2: userauth_pubkey_agent: no message sent

Try running the ssh client in verbose mode (-vvv for the most verbose)
-- maybe that will tell you why the public key authentication is
failing.

I believe there's also a debug/verbose mode for the server if you can't
figure it out from the client side.
