port 137 UDP
 

hi i am getting hits continously on my port 137 UDP ....in the firewall...
I have a linux server in a windows network...
Can someone please tell me the importance of port 137 UDP...i know that it is a Netbios port....but will blocking it cause any harm to my system accessing the internet??

It shouldn't be a problem per: NetBIOS

HTH,

Centinul

what is causing the hits
 

what do you think is causing the hits anyway....even it is netbois..??

Are these hits coming from the internet or are you part of a larger (say college campus) network? I know when I was at college I was getting hits on that port often, probably some legitimate and some not, but I didn't have any side effects when blocking it.

i am a part of a large windows network
 

i am a part of a large windows network....and i am not directly connected to the internet...but through a very secure proxy and a firewall called checkpoint....

Still what is the system of netbios....?? once i did block the port 137 then i couldnt browse the internet at all...it caused a lot of problems....
