OK, I was not quite right when I said that ssh works. When I ssh from one
working box into another using the -v option, this is what I get just
before the password prompt:

debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Next authentication method: gssapi-with-mic
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Next authentication method: publickey
debug1: Trying private key: /home/bjt/.ssh/identity
debug1: Trying private key: /home/bjt/.ssh/id_rsa
debug1: Trying private key: /home/bjt/.ssh/id_dsa
debug1: Next authentication method: password


When I ssh from the broken box, this is what I get:


debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Next authentication method: gssapi-with-mic
debug1: An invalid name was supplied
Cannot determine realm for numeric host address

debug1: Next authentication method: publickey
debug1: Trying private key: /home/bjt/.ssh/identity
debug1: Trying private key: /home/bjt/.ssh/id_rsa
debug1: Trying private key: /home/bjt/.ssh/id_dsa
debug1: Next authentication method: password

I'm googling on these errors, but so far, nothing that would indicate what
the problem might be.
