rpcinfo makes an RPC call to an RPC server and reports what it finds.
In the first synopsis, rpcinfo lists all the registered RPC services with rpcbind on host. If host is not specified, the local host is the default. If -s is used, the information is displayed in a concise format.
In the second synopsis, rpcinfo lists all the RPC services registered with 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 rpcbind protocol).
The third synopsis makes an RPC call to procedure 0 of prognum and versnum on the specified host and reports whether a response was received. The 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 rpcbind.
The prognum argument is a number that represents an RPC program number. If a versnum is specified, rpcinfo attempts to call that version of the specified prognum. Otherwise, rpcinfo attempts to find all the registered version numbers for the specified prognum 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 registered version.
The version number is required for -b and -d options.

Options
-m
Display a table of statistics of rpcbind operations on the given host. The table shows statistics for each version of 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 host.
-s
Display a concise list of all registered RPC programs on host. If host is not specified, it defaults to the local host.
-p
Probe rpcbind on host using version 2 of the rpcbind protocol, and display a list of all registered RPC programs. If host is not specified, it defaults to the local host. Note that version 2 of the rpcbind protocol was previously known as the portmapper protocol.
-t
Make an RPC call to procedure 0 of prognum on the specified host using TCP, and report whether a response was received. This option is made obsolete by the -T option as shown in the third synopsis.
-l
Display a list of entries with a given prognum and versnum on the specified host. Entries are returned for all transports in the same protocol family as that used to contact the remote rpcbind.
-b
Make an RPC broadcast to procedure 0 of the specified prognum and versnum and report all hosts that respond. If 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.
-d
Delete registration for the RPC service of the specified prognum and versnum. If 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 superuser who can delete any service.
-u
Make an RPC call to procedure 0 of prognum on the specified host using UDP, and report whether a response was received. This option is made obsolete by the -T option as shown in the third synopsis.
-aserv_address
Use serv_address as the (universal) address for the service on transport to ping procedure 0 of the specified prognum and report whether a response was received. The -T option is required with the -a option.
If versnum is not specified, rpcinfo tries to ping all available version numbers for that program number. This option avoids calls to remote rpcbind to find the address of the service. The serv_address is specified in universal address format of the given transport.
-nportnum
Use portnum as the port number for the -t and -u options instead of the port number given by rpcbind. Use of this option avoids a call to the remote rpcbind to find out the address of the service. This option is made obsolete by the -a option.
-Ttransport
Specify the transport on which the service is required. If this option is not specified, rpcinfo uses the transport specified in the NETPATHenvironment variable, or if that is unset or NULL, the transport in the netconfig database is used. This is a generic option, and can be used in conjunction with other options.
Display all of the RPC services of the local host.
rpcinfo cpuhope
Show all RPC services registered with rpcbind on the machine named cpuhope.
rpcinfo -s cpuhope
Same as the above command, but shows more concise information (the default information display can be quite lengthy). Output will resemble the following:
rpcinfo (報告RPC信息)

rpcinfo 描述
rpcinfo對RPC服務器進行RPC調用并報告其發現的內容。
在第一個概要中，rpcinfo列出了host上帶有rpcbind的所有已注冊的RPC服務。如果主機不被指定，本地主機是默認的。如果使用-s，則信息以簡潔的格式顯示。
在第二個提要中，rpcinfo列出了在rpcbind版本2中注冊的所有RPC服務。此外，請注意，在第一個和第二個提要中，信息的格式是不同的。這是因為第二個概要是用于收集顯示信息的較舊協議（rpcbind協議的版本2 ）。
第三個概要對指定主機上的prognum和versnum過程0進行RPC調用，并報告是否收到響應。的傳輸是具有用于給定服務接觸傳輸。通過調用遠程rpcbind獲得服務的遠程地址。
所述prognum參數是一個數字，代表一個RPC程序號。如果指定了versnum，則rpcinfo嘗試調用該版本的指定prognum。否則，rpcinfo嘗試通過調用版本0（假定不存在）來查找指定程序的所有注冊版本號；如果確實存在，則rpcinfo嘗試通過調用一個極高的版本號來獲取此信息，并嘗試調用每個已注冊的版本。
-b和-d選項需要版本號。

選件
如果未指定versnum，則rpcinfo嘗試ping通該程序號的所有可用版本號。此選項避免調用遠程rpcbind來查找服務的地址。該serv_address在給定的傳輸的通用地址格式指定。
Options
If versnum is not specified, rpcinfo tries to ping all available version numbers for that program number. This option avoids calls to remote rpcbind to find the address of the service. The serv_address is specified in universal address format of the given transport.

rpcinfo 例子
顯示本地主機的所有RPC服務。
顯示在名為cpuhope的計算機上向rpcbind注冊的所有RPC服務。
與上述命令相同，但顯示的信息更為簡潔（默認信息顯示可能會很長）。輸出將類似于以下內容：
顯示與計劃數的RPC服務是否prognum和版本versnum被注冊在指定的機器cpuhope為傳輸TCP。
顯示在本地計算機上用rpcbind協議版本2注冊的所有RPC服務。
刪除所有傳輸的有1服務（程序編號100008）的版本1的注冊。
與上面的示例相同，但按名稱指定walld。
Display all of the RPC services of the local host.
Show all RPC services registered with rpcbind on the machine named cpuhope.
Same as the above command, but shows more concise information (the default information display can be quite lengthy). Output will resemble the following:
Show whether the RPC service with program number prognum and version versnum is registered on the machine named cpuhope for the transport tcp.
Show all RPC services registered with version 2 of the rpcbind protocol on the local machine.
Delete the registration for version 1 of the walld (program number 100008) service for all transports.
Same as the above example, but specifies walld by name.
