    Subjectwhat's an evil packet ?
    Hi, 

    for the last 4 days we're getting the following message

    RPC: rpc_send sending evil packet:
    c84adc5e 01000000 00000000 00000000 00000000 00000000 00000000 01000000

    exactly every minute for just one dual-PPro200 box running Linux 2.0.30-SMP.
    when this happens, the NFS traffic to one SGI IRIX 5.3 box ("ceres") is dead,
    while networking (ping, telnet etc.) to ceres is still OK and NFS to other
    SGI boxes doesn't have a problem.

    what's this "evil packet", who is sending it to whom,
    and what do these numbers tell you ?

    here is a small snip from syslogs where NFS only was dead for a few minutes,
    usually this lasts *much* longer (*many* hours or until reboot).

    Jul 8 12:23:27 alamak kernel: NFS server ceres OK.


    any idea or hint ? we're running 2.0.30-SMP on this PC for a long time now
    with no problems until July 4th where this started.

    another dual-PPro200 box with identical setup doesn't show these messages
    or problem, neither do some single-PProswith 2.0.30, all in the same subnet
    connected to the same hub...
