    Hitting a wall with this one and would really appreciate some help from
    somebody, please.

    I have a problem trying to configure ssh to login automatically going
    from one host to another. Both servers have multiple LAN cards. Each
    server has a connection to a 100Mb public LAN (the primary interface)
    and another connection to a Gigabit private LAN. I'm trying to ssh
    between the servers via the Gigabit LAN, but get prompted for a
    password. This is because the public key generated by ssh-keygen on
    the source system has the public hostname at the end of the key.

    For example, xcucegedu-long-a$$-key-73467frfg guy@server1.co.uk

    Although this public key is in the destination hosts guy account (in
    ~/.ssh/auhorized_keys with 600 permissions) the sshd appears to ignore
    it as the session is coming from server1_p (the private Gigabit
    address).

    Is there a way of getting ssh-keygen to generate a public key for a
    particular LAN card (i.e. address) on a server? That way I could
    generate a key for the private address and sshd on the target server
    would hopefully validate me.

    Thanking you in advance.

    Guy
