samba - Oct 2001 - Subnet mask change- disables Samba (and telnet)

I'm not very experienced with networking, so please be patient ...


When I turn Samba on, the following message is displayed
"134.6.28.51 sent an invalid ICMP error to a broadcast", about once
every 20
seconds.

People in our IT dept. have tracked this down to an oscilloscope connected
to the network.
The scope is being used heavily, so I can't have it sent in for servicing or
disconnect it from the network.

I had tried re-directing the stderr from the SMBD and NMBD to an unused TTY,
but it appears Samba ISN'T generating these messages. It appears it is
reporting them to some other daemon, but I don't see any network daemon
running when I type ps -ax.

I had noticed that the subnet mask on my Linux box was 255.255.0.0, but on
my Windows machine was 255.255.255.0. To me, this doesn't seem right, so I
had changed the subnet mask on my Linux box to 255.255.255.0, and restarted
the appropriate services.

Now I can't connect via Samba or Telnet.

Am I using the correct subnet 255.255.255.0 ? Is there another parameter I
need to change to get my networking up and running ?

Thanks

I don't know if it matter, but 255.255.255.0 is normally used to route out
to
the internet.
