| 45 | .Sh SYNOPSIS | |
| 46 | .Nm portmap | |
| 47 | .Op Fl d | |
| 48 | .Sh DESCRIPTION | |
| 49 | .Nm Portmap | |
| 50 | is a server that converts | |
| 51 | .Tn RPC | |
| 52 | program numbers into | |
| 53 | .Tn DARPA | |
| 54 | protocol port numbers. | |
| 55 | It must be running in order to make | |
| 56 | .Tn RPC | |
| 57 | calls. | |
| 58 | .Pp | |
| 59 | When an | |
| 60 | .Tn RPC | |
| 61 | server is started, it will tell | |
| 62 | .Nm portmap | |
| 63 | what port number it is listening to, and what | |
| 64 | .Tn RPC | |
| 65 | program numbers it is prepared to serve. | |
| 66 | When a client wishes to make an | |
| 67 | .Tn RPC | |
| 68 | call to a given program number, | |
| 69 | it will first contact | |
| 70 | .Nm portmap | |
| 71 | on the server machine to determine | |
| 72 | the port number where | |
| 73 | .Tn RPC | |
| 74 | packets should be sent. | |
| 75 | .Pp | |
| 76 | .Nm Portmap | |
| 77 | must be started before any | |
| 78 | .Tn RPC | |
| 79 | servers are invoked. | |
| 80 | .Pp | |
| 81 | Normally | |
| 82 | .Nm portmap | |
| 83 | forks and dissociates itself from the terminal | |
| 84 | like any other daemon. | |
| 85 | .Nm Portmap | |
| 86 | then logs errors using | |
| 87 | .Xr syslog 3 . | |
| 88 | .Pp | |
| 89 | Option available: | |
| 90 | .Bl -tag -width Ds | |
| 91 | .It Fl d | |
| 92 | (debug) prevents | |
| 93 | .Nm portmap | |
| 94 | from running as a daemon, | |
| 95 | and causes errors and debugging information | |
| 96 | to be printed to the standard error output. | |

| 102 | .Sh BUGS | |
| 103 | If | |
| 104 | .Nm portmap | |
| 105 | crashes, all servers must be restarted. | |
