TotalNET Advanced Server 5.2 Reference Manual

NB-session-port

These attributes specify the TCP/UDP port numbers at which NetBIOS services reside. By default, these attributes do not exist, which means the same as 137, 138, and 139, respectively. Since NetBIOS clients can rarely use non-standard port numbers, these attributes generally apply only during development or troubleshooting. Do not change these attributes from their default values.

Usage:

tntransport -M -n transport
 	-a {NB-name-port|NB-dgram-port|
 	NB-session-port}=value
