Are the ports for Pathworks Advanced Server configurable?

[David Lloyd_4]

Hi all,
I've seen from several posts that AVS V7.3-A4 (on VMS 7.3-2 axp) uses port 139 among others, and that this is not configurable.
In order to document that formally, I'd like to cite a reference. Does anyone know where that information might be found?
Thanks!

Port 139 is a NetBIOS port, and specifically part of Windows File and Printer Sharing.

It's hazardous to have this open outside of a firewall (which is probably why there's a discussion here), but you probably don't want to be running a SMB or CIFS stack on an open network regardless.

But on the LAN, this is how SMB and CIFS clients access the services provided by PATHWORKS, Advanced Server, Samba, or CIFS.

At least Samba and CIFS have a way to alter this port to another. But AFAIK, the port is necessary for NetBIOS traffic. Or you can (try to) shut down everything that does NetBIOS inside the particular package, if that's even feasible.

Here's a reference:

Or poke around in most any description of the NetBIOS protocol.
