    Hi there,

    I have a Solaris 7 (sparc) installation, with the recomended patch-batch
    installed. This particular installation emits 127.0.0.x addresses on
    the ethernet, and I wonder if anyone has any pointers what could cause
    this. (ip addresses has changed to protect the guilty).

    # ifconfig -a
    lo0: flags=849<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232
            inet netmask ff000000
            inet netmask ffffff00 broadcast
            ether 8:0:20:c4:ad:45

    # netstat -nr

    Routing Table:
      Destination Gateway Flags Ref Use Interface
    -------------------- -------------------- ----- ----- ------ --------- U 3 31742 hme0 U 3 0 hme0
    default UG 0 379177 UH 0 84159 lo0

    Here is a text dump from Ethereal that displays the offensive packets:

    Please advice.
