Windows likes to periodically announce itself to the network at large,
as samba does.
Now I would like to monitor this activity to see what it is, AND I
want to do this from the relative safety of my linux m/c. Can anyone
advise me, bearing in mind my present knowledge of networking, how I
might set about this.
Packet sniffers are your friends. I like snort - it's an IDS, but
includes a handy packet sniffer. Something like "snort -dvi ppp0" on
your firewall box, and see what ports the windows box is talking on.
You'll probably just see packets containing the machine's name and so
forth. Another popular packet sniffer is tcpdump.
