nbd(1Mtcp)

nbd -- NetBIOS daemon

Synopsis

in.nbd

Description

The NetBIOS daemon, in.nbd, initializes NetBIOS, then remains active to create new TCP endpoints for NetBIOS and recycle used ones. NetBIOS initialization consists of performing an ioctl to set certain configuration parameters and linking UDP and TCP endpoints to NetBIOS. Two UDP endpoints and one TCP endpoint are used for the name, datagram, and session services, respectively. Each NetBIOS session requires one TCP endpoint. As sessions terminate, their TCP endpoints are unlinked. From time to time, new TCP endpoints must be linked to NetBIOS to use for new sessions. The daemon listens for messages from NetBIOS instructing it to unlink certain endpoints and/or provide new ones.

The script /etc/netbios (see netbios(1Mtcp)) reads default values for the NetBIOS configuration parameters from the file /etc/inet/nb.conf, sets these in its environment, and then starts in.nbd. in.nbd then reads these environment variables to determine the NetBIOS configuration parameter values. in.nbd fails if it does not find values for all configuration parameters set in the environment.

Diagnostics

in.nbd uses syslogd(1M) to report errors.
