    hi

    (sorry if this is a duplicate, but I did not find the archives
    for this list)

    I am using 2.6.0, for all my computers.

    On my server, I have 2 net cards: one only for ADSL with PPPoE,
    the other for the local network, and I use masquerading between the two.

    Today I tried to set up NFS on the server, and it does not work ok.

    NFS seems to have no problems in writing large files, but it
    goes haywire when I start compiling the kernel on the NFS client
    (the kernel is inside the NFS mount): on the client I see these messages

     kernel: UDP: short packet: From 192.168.1.1:0 0/136 to 192.168.1.2:1
     kernel: UDP: short packet: From 192.168.1.1:8224 8224/128 to 192.168.1.2:8224
    (many of these)

    and even this very astounding message

     kernel: UDP: short packet: From 212.216.112.112:6299 33691/126 to 192.168.1.2:256

    and NFS does not work; but I am pretty sure that the local net is OK
    (I use it a lot )
    I also tried to ping at the same time when I was experiencing
    the problem, and ping works ok.

    Am I the only one seeing this?

    a.
