Minor correction: It's not Netbui that generates these udp packets but
rather Netbios, an integral part of SMB in Windows (not nessasarily in
Samba).
sory for the "buggy" info
Answers:
1) Netbui gerenates these packets as part of it's "housekeeping" tasks
(related to WINS server location, etc.).
2) 2 ways to surpress this a) make a diald rule to ignore the udp
packets. b) make a firewalling rule to filter out these packets (I
filter them out before they get to diald).
example (place in /etc/rc.d/rc.local):
#Block Windows housekeeping trafic from triggering autodial etc.
/sbin/ipfwadm-wrapper -F -a deny -P tcp -S 0.0.0.0/0 137:139
/sbin/ipfwadm-wrapper -F -a deny -P udp -S 0.0.0.0/0 137:139
(note: I simply used ipfwadm-wrapper instead of rewriting the rule in
ipchains. Lazy, I know, but it works).
3) If you are using Microsoft networking to share drives and printers
(vial the SMB - Session Message Block) protocol, the win. clients will
typically try to find a WINS sever. Want 'em to stop that? Stop using
SMB networking (easiest answer).

Subject: diald and netbeui
I _know_ this has been asked multiple times and I _know_ that I've done a
bunch of the asking. Unfortunately, noone has given me a good definitive
answer yet. I've gotton pointers to archives that I cannot find and
approximate answers but nothing concrete.
Here's the deal. I have a working network comprised of a linux server
and 2
win98 machines. The network is working correctly, I can ping all three
machines, ppp works, diald works, and all is well and good. I want to
turn
on windows networking so that I can share resources on my windows
network.
I added netbeui protocol to both machines and added the file printing and
sharing service. As soon as I boot the win98 machines, diald is
triggered.
Here are my questions:
1) Why, exactly, does netbeui generate udp packets that trigger diald?
2) How do I suppress this so that diald ignores the damned broadcasts?
3) Do I even need netbeui to share resources on my win98 machines?
Thanks for a quick response!
...Jake
