+.Sh NAME
+.Nm portmap
+.Nd
+.Tn DARPA
+port to
+.Tn RPC
+program number mapper
+.Sh SYNOPSIS
+.Nm portmap
+.Op Fl dv
+.Sh DESCRIPTION
+.Nm Portmap
+is a server that converts
+.Tn RPC
+program numbers into
+.Tn DARPA
+protocol port numbers.
+It must be running in order to make
+.Tn RPC
+calls.
+.Pp
+When an
+.Tn RPC
+server is started, it will tell
+.Nm portmap
+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 portmap
+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
+Normally
+.Nm portmap
+forks and dissociates itself from the terminal
+like any other daemon.
+.Nm Portmap
+then logs errors using
+.Xr syslog 3 .
+.Pp
+Option available:
+.Bl -tag -width Ds
+.It Fl d
+(debug) prevents
+.Nm portmap
+from running as a daemon,
+and causes errors and debugging information
+to be printed to the standard error output.
+.It Fl v
+(verbose) causes
+.Nm portmap
+to give more logging information to
+.Xr syslogd 8.
+.Pp
+.Sh Access control
+By default, host access control is enabled. However, the host that runs
+the portmapper is always considered authorized. The host access control
+tables are never consulted with requests from the local system itself;
+they are always consulted with requests from other hosts.
+.Pp
+In order to avoid deadlocks, the portmap program does not attempt to
+look up the remote host name or user name, nor will it try to match NIS
+netgroups. The upshot of all this is that only network number patterns
+will work for portmap access control.
+.Pp
+Sample entries for the host access-control files are:
+
+.Nm /etc/hosts.allow:
+ portmap: your.sub.net.number/your.sub.net.mask
+ portmap: 255.255.255.255 0.0.0.0
+
+.Nm /etc/hosts.deny
+ portmap: ALL
+
+The syntax of the access-control files is described in the
+.Xr hosts_access 5
+and
+.Xr hosts_options 5
+manual page that comes with the tcp wrapper (log_tcp)
+sources. The safe_finger command comes with later wrapper releases.
+.Pp
+The first line in the hosts.allow file permits access from all systems
+within your own subnet. Some rpc services rely on broadcasts and will
+contact your portmapper anyway; and once an intruder has access to your
+local network segment you're already in deep trouble.
+.Pp
+The second line in the hosts.allow file may be needed if there are
+any PC-NFS systems on your network segment.
+.Pp
+For security reasons, the portmap process drops root privilegs after
+initialization. The access control files should therefore be readable
+for group or world.

+If
+.Nm portmap
+crashes, all servers must be restarted.
