It must be running in order to make .Tn RPC calls. .Pp When an .Tn RPC server is started, it will tell .Nm what port number it is listening to, and what .Tn RPC program numbers it is prepared to serve. When a client wishes to make an .Tn RPC call to a given program number, it will first contact .Nm on the server machine to determine the port number where .Tn RPC packets should be sent. .Pp .Nm Portmap must be started before any .Tn RPC servers are invoked. .Pp .Nm Portmap uses .Xr hosts_access 5 access control by default. Access control patterns may only reference IP addresses. .Pp Normally .Nm forks and dissociates itself from the terminal like any other daemon. .Nm Portmap then logs errors using .Xr syslog 3 . .Pp The following options are available: .Bl -tag -width indent .It Fl d Prevent .Nm from running as a daemon, and causes errors and debugging information to be printed to the standard error output. .It Fl v Enable verbose logging of access control checks. .It Fl h Specify specific IP addresses to bind to for UDP requests. This option may be specified multiple times and is typically necessary when running on a multi-homed host. If no .Fl h option is specified, .Nm will bind to .Dv INADDR_ANY , which could lead to problems on a multi-homed host due to .Nm returning a UDP packet from a different IP address than it was sent to. Note that when specifying IP addresses with .Fl h , .Nm will automatically add .Li 127.0.0.1 to the list. .El .Sh SEE ALSO .Xr hosts_access 5 , .Xr inetd.conf 5 , .Xr inetd 8 , .Xr rpcinfo 8 .Sh BUGS If .Nm crashes, all servers must be restarted. .Sh HISTORY The .Nm command appeared in .Bx 4.3 .
