Re: [OS X] Disabling NetBIOS broadcasts in Leopard

AFAIK, to kill netbios completely you'll need to add the following lines to /etc/smb.conf.

disable netbios = yes
smb ports = 445


You'll also need to stop nmbd from starting. You can do that with the following command:

sudo launchctl unload -w /System/Library/LaunchDaemons/nmbd.plist


Doing this will probably break name resolution of windows clients via netbios (of course). It may also break browsing windows networks.

This disables the NetBIOS server. The NetBIOS client still sends out broadcasts. This is disabled easily in Windows but I now have a support call into Apple to find out how to disable on OS X.

Why would I want unsolicited broadcasts coming out of my machine?

Use the built in firewall to stop the broadcasts.
