2: .TH PORTMAP 8C "1 February 1985"
3: .SH NAME
4: portmap \- DARPA port to RPC program number mapper
5: .SH SYNOPSIS
6: .B /usr/etc/rpc.portmap
7: .SH DESCRIPTION
8: .I Portmap
9: is a server that converts RPC program numbers
10: into DARPA protocol port numbers.
11: It must be running in order to make RPC calls.
12: .PP
13: When an RPC server is started, it will tell
14: .I portmap
15: what port number it is listening to,
16: and what RPC program numbers it is prepared to serve.
17: When a client wishes to make an RPC call to a given program number,
18: it will first contact
19: .I portmap
20: on the server machine to determine
21: the port number where RPC packets should be sent.
22: .PP
23: Normally, standard RPC servers are started by
24: .IR inetd (8c),
25: so
26: .I portmap
27: must be started before
28: .I inetd
29: is invoked.
30: .SH "SEE ALSO"
31: servers(5), rpcinfo(8), inetd(8)
32: .SH BUGS
33: If
34: .I portmap
35: crashes, all servers must be restarted.
