Sh DESCRIPTION
Nm
makes an RPC call to an RPC
server and reports what it finds.
Pp
In the first synopsis,
Nm
lists all the registered RPC services with
Nm rpcbind
on
Ar host .
If
Ar host
is not specified, the local host is the default.
If
Fl s
is used, the information is displayed in a concise format.
Pp
In the second synopsis,
Nm
lists all the RPC services registered with
Nm rpcbind ,
version 2.
Also note that the format of the information
is different in the first and the second synopsis.
This is because the second synopsis is an older protocol used to
collect the information displayed (version 2 of the
Nm rpcbind
protocol).
Pp
The third synopsis makes an RPC call to procedure 0
of
Ar prognum
and
Ar versnum
on the specified
Ar host
and reports whether a response was received.
Ar transport
is the transport which has to be used for contacting the
given service.
The remote address of the service is obtained by
making a call to the remote
Nm rpcbind .
Pp
The
Ar prognum
argument is a number that represents an RPC program number.
If a
Ar versnum
is specified,
Nm
attempts to call that version of the specified
Ar prognum .
Otherwise,
Nm
attempts to find all the registered version
numbers for the specified
Ar prognum
by calling version 0,
which is presumed not to exist;
if it does exist,
Nm
attempts to obtain this information by calling
an extremely high version number instead,
and attempts to call each registered version.
Note: the version number is required for the
Fl b
and
Fl d
options.
Sh OPTIONS
Bl -tag -width indent
It Fl T Ar transport
Specify the transport on which the service is required.
If this option is not specified,
Nm
uses the transport specified in the
Ev NETPATH
environment variable, or if that is unset or null, the transport
in the
Xr netconfig 5
database is used.
This is a generic option,
and can be used in conjunction with other options as
shown in the SYNOPSIS.
Pp
It Fl a Ar serv_address
Use
Ar serv_address
as the (universal) address for the service on
Ar transport
to ping procedure 0
of the specified
Ar prognum
and report whether a response was received.
The
Fl T
option is required with the
Fl a
option.
Pp
If
Ar versnum
is not specified,
Nm
tries to ping all
available version numbers for that program number.
This option avoids calls to remote
Nm rpcbind
to find the address of the service.
The
Ar serv_address
is specified in universal address format of the given transport.
Pp
It Fl b
Make an RPC broadcast to procedure 0
of the specified
Ar prognum
and
Ar versnum
and report all hosts that respond.
If
Ar transport
is specified, it broadcasts its request only on the
specified transport.
If broadcasting is not supported by any
transport,
an error message is printed.
Use of broadcasting should be limited because of the potential for adverse
effect on other systems.
Pp
It Fl d
Delete registration for the RPC service of the specified
Ar prognum
and
Ar versnum .
If
Ar transport
is specified,
unregister the service on only that transport,
otherwise unregister the service on all
the transports on which it was registered.
Only the owner of a service can delete a registration, except the
super-user who can delete any service.
Pp
It Fl l
Display a list of entries with a given
Ar prognum
and
Ar versnum
on the specified
Ar host .
Entries are returned for all transports
in the same protocol family as that used to contact the remote
Nm rpcbind .
Pp
It Fl m
Display a table of statistics of
Nm rpcbind
operations on the given
Ar host .
The table shows statistics for each version of
Nm rpcbind
(versions 2, 3, and 4), giving the number of times each procedure was
requested and successfully serviced, the number and type of remote call
requests that were made, and information about RPC address lookups that were
handled.
This is useful for monitoring RPC activities on
Ar host .
Pp
It Fl n Ar portnum
Use
Ar portnum
as the port number for the
Fl t
and
Fl u
options instead of the port number given by
Nm rpcbind .
Use of this option avoids a call to the remote
Nm rpcbind
to find out the address of the service.
This option is made obsolete by the
Fl a
option.
Pp
It Fl p
Probe
Nm rpcbind
on
Ar host
using version 2 of the
Nm rpcbind
protocol,
and display a list of all registered RPC programs.
If
Ar host
is not specified, it defaults to the local host.
Note: version 2 of the
Nm rpcbind
protocol was previously known as the portmapper protocol.
Pp
It Fl s
Display a concise list of all registered RPC programs on
Ar host .
If
Ar host
is not specified, it defaults to the local host.
Pp
It Fl t
Make an RPC call to procedure 0 of
Ar prognum
on the specified
Ar host
using TCP,
and report whether a response was received.
This option is made obsolete by the
Fl T
option as shown in the third synopsis.
Pp
It Fl u
Make an RPC call to procedure 0 of
Ar prognum
on the specified
Ar host
using UDP,
and report whether a response was received.
This option is made obsolete by the
Fl T
option as shown in the third synopsis.

Sh EXAMPLES
To show all of the RPC services registered on the local machine use:

Pp
To show all of the RPC
services registered with
Nm rpcbind
on the machine named
Nm klaxon
use:
Pp

Pp
The information displayed by the above commands can be quite lengthy.
Use the

       example% rpcinfo -s klaxon
Ed
Bl -column "program" "version(s)" "local,tcp,udp,tcp6,udp6" "nlockmgr" "super-user"

Pp
To show whether the RPC
service with program number
Ar prognum
and version
Ar versnum
is registered on the machine named
Nm klaxon
for the transport TCP
use:
Pp
Bd -literal
       example% rpcinfo -T tcp klaxon prognum versnum
Ed
Pp
To show all RPC
services registered with version 2 of the
Nm rpcbind
protocol on the local machine use:
Bd -literal
       example% rpcinfo -p
Ed
Pp
To delete the registration for version
1 of the
Nm walld
(program number 100008)
service for all transports use:
Bd -literal
       example# rpcinfo -d 100008 1
