NAME
rpcinfo -- report RPC information SYNOPSIS
rpcinfo [--rpcbvers version] [-m | -s] [host] rpcinfo [--rpcbvers version] -T netid host program [version] rpcinfo [--rpcbvers version] -a server address -T netid program [version] rpcinfo [--rpcbvers version] -b [-T netid] program version rpcinfo [--rpcbvers version] -d [-T netid] program version rpcinfo -l [-T netid] [host] program version rpcinfo [--rpcbvers version] --getaddr [-T netid] [host] program version rpcinfo --getversaddr [-T netid] [host] program version rpcinfo --indirect [-T netid] [host] program version rpcinfo [--rpcbvers version] --time [-T netid] [host] rpcinfo {--help | -h} rpcinfo -p [host] rpcinfo [-n portnum] -u host program [version] rpcinfo [-n portnum] -t host program [version] DESCRIPTION
rpcinfo makes an RPC call to an RPC server and reports what it finds. Unless otherwise specified or noted below the default rpcbind protocol version is 3. With no or only generic options, call the rpcbind dump procedure on the specified host or ``localhost'' if host is not speci- fied and display the results. For versions 3 and 4 display the program number, the version, the ``netid'', the universal address that the services is listening on, symbolic name of the program if known, and then the owner that registered the <program, version, netid, address> tuple. For version 2 of the protocol list the program, version, protocol, port, and symbolic program name. See the --summary option below for a typically more useful output. rpcbind defaults the netid to ``tcp'' for the dump procedure. The program argument can be either a name or a number. If a version is specified, rpcinfo attempts to call that version of the specified program. Otherwise, if the version is optional rpcinfo attempts to find all the registered version numbers for the specified program by calling version 0 (which is presumed not to exist; if it does exist, rpcinfo attempts to obtain this information by calling an extremely high version number instead) and attempts to call each regis- tered version. A required transport option is needed for the second and third lines of the synopsis which is used to ping, i.e., call the null procedure of the specified program and version. The results will be displayed on stdout. If version is not specified each valid version found as described above will be called. The third synopsis will use the supplied universal address over the transport specified by netid to call the null pro- cedure of the specified program in the same manner as above. In addition the last two lines of the synopsis can ``ping'' the server as described in the Legacy Options section below. GENERIC OPTIONS
--rpcbvers version Attempt to use the supplied rpcbind version. Note some options below are version specific and this option may be ignored. If specify- ing version 2 (portmapper), netid below must be one of ``udp'' or ``tcp''. -T netid Specify the netid to use. Supported netids are ``udp'', ``tcp'', ``udp6'', and ``tcp6''. --timeout seconds Timeout used in creating client handles and the client calls to rpcbind. Current default is 12 seconds. Generic options may be supplied with any of the rpcinfo options below, though some options will override their values. LEGACY OPTIONS
The options below imply version 2 (portmapper) rpcbind calls. They are compatible with older versions of rpcinfo. {-p | --portmap} [-T netid] [host] Probe the portmapper on host, and print a list of all registered RPC programs. If host is not specified, it defaults to the value ``localhost''. {-u | --udpping} host program [version] Make an RPC call to the NULL procedure of program on the specified host using UDP, and report whether a response was received. {-t | --tcpping} host program [version] Make an RPC call to the NULL procedure of program on the specified host using TCP, and report whether a response was received. {-n | --portnum} portnum Use portnum as the port number for the -t and -u options instead of the port number given by the portmapper. OPTIONS
{-b | --broadcast} program version Make an RPC multicast over INET6 to the RPCB_MULTICAST_ADDR, ``FF02::202'', and broadcast over INET using UDP to procedure 0 of the specified program and version and report all hosts that respond. rpcifno will first use RPCBIND version 3 and then call the broad- cast procedure of the portmapper protocol to collect older hosts. There is a reply cache kept so duplicates will not be returned unless the cache fills. Note that the -b option by its self is compatible with the older portmapper. However, specifying --rpcbvers 2 will short circuit the rpcbind version 3 calls and only call the portmapper. {-d | --delete} [-T netid] program version Delete registration for the RPC service of the specified program and version. If the netid is specified, only unregister the program and version over that transport. This option can be exercised only by the super-user or the user who registered the the RPC service. --getaddr [-T netid] [host] program version Get the universal address that the client can use to contact the program and version from host over netid. If host is not specified localhost is assumed. If netid is not specified ``udp'' is assumed. If the specified version is not available but some other version is, return the universal address for one of those versions of the program. --getversaddr [-T netid] [host] program version Get the universal address that the client can use to contact the program and version from host over netid. If host is not specified localhost is assumed. If netid is not specified ``udp'' is assumed. If the version is not available then that will be indicated. This requires the remote rpcbind support version 4. -h Print out the synopsis of this program. --help Print out the synopsis and an explanation of the options. --indirect [-T netid] [host] program version Send a indirect call to the null procedure of program and version on the specified host or localhost. This requires the remote rpcbind to support version 4. {-l | --list} [-T netid] [host] program version List the transports available over the transport family specified by the netid for the given program and version on the optional host or localhost if not specified. Requires the remote rpcbind to support version 4. The default transport family is INET. {-m | --metrics} Print the metrics of rpcbind daemon for the specified host or localhost if not specified. Requires support for rpcbind version 4 on the remote. {-s | --summary} Print a summary of programs registered on host or ``localhost'' if host is not specified. For each program registered list any ver- sions followed by any transports supported by that program. Try to list the symbolic name of the transport and the owner that regis- tered the program. --time [host] Return rpcbind's version of time on the specified host. EXAMPLES
To show all of the RPC services registered on the local machine use: example% rpcinfo To show all of the RPC services registered on the machine named klaxon use: example% rpcinfo klaxon More usefully to show the services registered on klaxon use: example% rpcinfo -s klaxon To show all of the RPC services from an older host only running version 2 of rpcbind on a host named horn use: example% rpcinfo -p horn To show all machines on the local net that are running the NFS File service use: example% rpcinfo -b nfs 'version' where 'version' is one of the current nfs versions of interest. To delete the registration for version 1 of the rquotad service use: example% rpcinfo -d rquotad 1 SEE ALSO

In summary mode the maximum number of versions and transports is 16. The first 16 versions and the first 16 transports received from the server are displayed and the rest is silently ignored. In the second synopsis line, for a host that is specified as a link-local INET6 address will always return ``no route to host''. In releases prior to SunOS 3.0, the Network File System (NFS) did not register itself with the portmapper; rpcinfo cannot be used to make RPC calls to the NFS server on hosts running such releases.
