You might want to add 135, IIRC.
you can enable iptables LOG as last rule to see what packets get droped to
find the culprit.
Or maybe iptraf

	You would have to have appropriate ACCEPT statements in the
	lan table --- cant tell why its not working since you haven't listed
	the lan table.

Problem with samba

[Reinaldo Brandão Gomes]

Hello, guys

I am having a problem with the processes smbd and nmbd.  When nmbd starts on our sun, running solaris 2.7 and samba 1.9, it goes into a extremely high CPU utilization (over 99%).

Our smb.conf has been untouched for 8 years,so far, and I don't think this is a problem with it.

Running "gdb nmbd 2830 gave me:"

"/usr2/local/bin/gdb attach 2830

Can someone, please, point me to a good way of troubleshoot this problem.

Any help will be greatly appreciated, once our client has 6 machines with this problem and all its data needs to be available by samba.

Thanks,
