Hi,

I am trying to use a 2.5.1p1 server with 2.4 clients. I'd like to
avoid converting the 50+ Amanda client boxes. I am testing against
a 2.4.4p3 client. The server amcheck times out waiting for ACK.
The amandad debug file on the client shows that security was passed:

        amandad: time 0.000: got packet:
        --------
        Amanda 2.5 REQ HANDLE 000-00000000 SEQ 1160853109
        SECURITY USER amandabackup
        SERVICE noop
        OPTIONS features=fffffeff9ffeffffff7f;
        --------

        amandad: time 0.000: sending ack:
        ----

        OPTIONS features=fffffeff9ffeffffff7f;
        ----

They are talking, but not in sync. Any suggestions? Thanks.
