    Hi, Patrick,

    your advice was a ful hit. I compiled ssh-3.2.2 with "--without-ipv6"
    and gcc (but not mipspro compiler). Now, ssh-3.2.2 client runs.

    But when using mipspro-7.3.1.3m, ssh'ing to some target fails with
    the following msg:

            warning: Authentication failed.
            Disconnected; key exchange or algorithm negotiation failed (Key exchange failed.).

    Regards

    Joachim Backes
