portmap

     portmap [-d] [-f] [-t dir] [-v] [-V] [-i address] [-l] [-u uid] [-g gid]

DESCRIPTION
     Portmap is a server that converts RPC program numbers into DARPA protocol
     port numbers.  It must be running in order to make RPC calls.

     When an RPC server is started, it will tell portmap what port number it
     is listening to, and what RPC program numbers it is prepared to serve.
     When a client wishes to make an RPC call to a given program number, it
     will first contact portmap on the server machine to determine the port
     number where RPC packets should be sent.

     Portmap must be started before any RPC servers are invoked.

     Normally portmap forks and dissociates itself from the terminal like any
     other daemon.  Portmap then logs errors using syslog(3).

     Portmap records all current mapping in the file /var/run/portmap_mapping
     so that if it gets killed and restarted, it can reload the mapping for
     currently active services.

     Options available:

     -V      Display version number and exit.

     -d      (debug) prevents portmap from running as a daemon, and causes
             errors and debugging information to be printed to the standard
             error output.

     -f      (foreground) prevents portmap from running as a daemon, and
             causes log messages to be printed to the standard error output.

     -t dir  (chroot) tell portmap to chroot(2) into dir.  dir should be
             empty, not writable by the daemon user, and preferably on a
             filesystem mounted read-only, noexec, nodev, and nosuid.

     -u uid

     -g gid  Set the user-id and group-id of the running process to those
             given, rather than the compiled-in defaults of 1/1.

     -v      (verbose) run portmap in verbose mode.

     -i address
             bind portmap to address. If you specify 127.0.0.1 it will bind to
             the loopback interface only.

     -l      bind portmap to the loop-back address 127.0.0.1.  This is a
             shorthand for specifying 127.0.0.1 with -i.

     This portmap version is protected by the tcp_wrapper library. You have to
     give the clients access to portmap if they should be allowed to use it.
     To allow connects from clients of the network 192.168. you could use the
     following line in /etc/hosts.allow:

     For further information please have a look at the tcpd(8), hosts_allow(5)
     and hosts_access(5) manual pages.
