Netbios datagram service Provides datagram service (i.e., message structured unreliable delivery service with multicast capability)
Understood, but is that a security risk? By shutting this port, what functionality am I losing?
Re: Understood, but is that a security risk? Based on the document found at: »support.microsoft.com/default.as···&SD=HSCH
It appears that port 138/udp is used to broadcast information on browse lists and elections from a Windows Master Browser to Windows workstations.
If you filter (block) this port over a LAN, your ability to browse other machines on the LAN may be limited.
This port can be filtered from leaving your LAN (going out to the Internet) with no problems.

Re: How to POrt shut? what os?
average joe winmx uses this port for downloading
Re: average joe Don't worry about it is it is a UDP port...if you are behind a Linux box...you can ignore it completely...it is a connectionless UDP port with minimal security risk. Even on windows...if only your UDP ports are open...relax...nobody is going to be playing with you much, ie, It is much easier to steal a car with the keys in it...why would I want to sit a plug away at a machine that is locked down a bit...when there are so many that are wide open.
winmx winmx uses tcp ports only in the high 6 or 7 000 ranges for all of its functions.
