|
|
|
.Nm portmap
|
2019-03-03 10:28:33 -08:00
|
|
|
is a server that converts RPC program numbers into Internet
|
1995-10-18 01:37:01 -07:00
|
|
|
protocol port numbers.
|
2015-09-10 08:16:43 -07:00
|
|
|
It must be running in order to make RPC calls.

2015-09-10 08:16:43 -07:00

|
When an RPC server is started, it will tell
|
1995-10-18 01:37:01 -07:00
|
|
|
.Nm portmap
|
2015-09-10 08:16:43 -07:00
|
|
|
what port number it is listening to, and what RPC
|
1995-10-18 01:37:01 -07:00
|
|
|
program numbers it is prepared to serve.
|
2015-09-10 08:16:43 -07:00
|
|
|
When a client wishes to make an RPC
|
1995-10-18 01:37:01 -07:00
|
|
|
call to a given program number,
|
|
|
|
|
it will first contact
|
|
|
|
|
.Nm portmap
|
|
|
|
|
on the server machine to determine
|
2015-09-10 08:16:43 -07:00
|
|
|
the port number where RPC packets should be sent.
|
1995-10-18 01:37:01 -07:00
