NAME
portmap —
Internet protocol port to RPC program
number mapper
SYNOPSIS
portmap |
[-d] |
DESCRIPTION
portmap is a server that converts RPC program numbers
into Internet protocol port numbers. It must be running in order to make RPC
calls.
When an RPC server is started, it will tell
portmap what port number it is listening to, and
what RPC program numbers it is prepared to serve. When a client wishes to
make an RPC call to a given program number, it will first contact
portmap on the server machine to determine the port
number where RPC packets should be sent.
portmap must be started before any RPC
servers are invoked.
Normally portmap forks and dissociates
itself from the terminal like any other daemon.
portmap then logs errors using
syslog(3).
The options are as follows:
-d- (debug) prevents
portmapfrom running as a daemon, and causes errors and debugging information to be printed to the standard error output.
SEE ALSO
HISTORY
The portmap command appeared in
4.3BSD.
BUGS
If portmap crashes, all servers must be
restarted.
