Sun RPC source (part 9 of 11). This software package contains code
and documentation for Revision 3.0 of the Sun Remote Procedure Call
library. In addition, a beta version of the XDR/RPC protocol compiler
is included. Comments about this latest release may be mailed to
sun!rpc or rpc@sun.com.

X.SH NAME
Xportmap \- DARPA port to RPC program number mapper
X.SH SYNOPSIS
X.B /usr/etc/rpc.portmap
X.SH DESCRIPTION
X.IX "portmap command" "" "\fLportmap\fP \(em DARPA to RPC mapper"
X.IX "DARPA to RPC mapper" "" "DARPA to RPC mapper \(em \fLportmap\fP"
X.I Portmap
Xis a server that converts RPC program numbers
Xinto DARPA protocol port numbers.
XIt must be running in order to make RPC calls.
X.PP
XWhen an RPC server is started, it will tell
X.I portmap
Xwhat port number it is listening to,
Xand what RPC program numbers it is prepared to serve.
XWhen a client wishes to make an RPC call to a given program number,
Xit will first contact
X.I portmap
Xon the server machine to determine
Xthe port number where RPC packets should be sent.
X.PP
XNormally, standard RPC servers are started by
X.IR inetd (8c),
Xso
X.I portmap
Xmust be started before
X.I inetd
Xis invoked.
X.SH "SEE ALSO"
Xservers(5), rpcinfo(8), inetd(8)
X.SH BUGS
XIf
X.I portmap
Xcrashes, all servers must be restarted.
