sent an invalid ICMP error to a broadcast.

[Robert Bartels]

Hello,

Yes you both are right about the root of the problem being a misconfigured
tcp/ip stack.
The problem is that I have no control over that machine, or the network its
on.
But... Last year I was able to sqwelch the error message by using a command
in
one of the network startup scripts... The solution was found in the
archives...
Since the archives aren't online.. I can't find the solution, but one does
exist..

Thanks

Bob

No and yes : i knew this error message well and had to live with it until we
cut our LAN into some VLANs.
The error comes (in our case) from buggy mainframe equipment.

The error appears always and on each machine running samba (all versions)
when the nmbd are started.
The error disappears immediately on all machines when the nmbd are stopped.

Sorry, but IMHO the only thing you could do is to bring these machines (the
ones that send the invalid packets) into a separate LAN Segment (via VLAN or
router, just as you want)
