    HI,

    try to clean up any key files (any host informations) and then establish
    a new connection....
    then you should be ask for a new key, maybe this 'll resolve your
    problem....

    by the way : most of the UNIX - you'll find these files in /etc/openssh
    or /etc/ssh....

    cheers
    der laff
