NAME¶

xmlrpc - makes an XML-RPC remote procedure call and displays the response

SYNOPSIS¶

      xmlrpc url method parameters [-transport=transportname]


                                   [-username=username -password=passwd]


                                   [-curlinterface={interface|host}]


                                   [-curlnoverifypeer]


                                   [-curlnoverifyhost]

DESCRIPTION¶

This program is used to execute Remote Procedure Calls (RPC) using a XML-RPC client. Its main purpose is debugging and learning since RPC are usually embedded in source code of other programs.

ARGUMENTS¶

url

This is the URL of the XML-RPC server. As XML-RPC uses HTTP, this must be an HTTP url. However, if you don't specify a type ("http:") in the URL, xmlrpc assumes an "http://" prefix and a "/RPC2" suffix. RPC2 is the conventional file name for an XML-RPC responder.

method

The name of the XML-RPC method you want to invoke.

parameters

List of parameters for the RPC. xmlrpc turns each of these arguments into an XML-RPC parameter, in the order given. You may specify no parameters if you like.

OPTIONS¶

-transport=transportname

This selects the XML transport facility (e.g. libwww) that xmlrpc uses to perform the RPC. The name transportname is one that the Xmlrpc-c programming library recognizes. This is typically libwww, curl, and wininet. By default, xmlrpc lets the Xmlrpc-c library choose.

-username=username

-password=passwd

These two options, which must be used together, cause the client to authenticate itself to the server, if the server requires it, using HTTP Basic Authentication and the specified username and password.

-curlinterface={interface|host}

This option gives the "interface" option for a Curl XML transport. The exact meaning of this option is up to the Curl library, and the best documentation for it is the manual for the 'curl' program that comes with the Curl library. But essentially, it chooses the local network interface through which to send the RPC. It causes the Curl library to perform a "bind" operation on the socket it uses for the communication. It can be the name of a network interface (e.g. on Linux, "eth1") or an IP address of the interface or a host name that resolves to the IP address of the interface. Unfortunately, you can't explicitly state which form you're specifying, so there's some ambiguity. Examples: -interface=eth1 -interface=64.171.19.66 -interface=giraffe.giraffe-data.com This option causes xmlrpc to default to using the Curl XML transport. You may not specify any other transport.

-curlnoverifypeer

This option gives the "no_ssl_verifypeer" option for the Curl XML transport, which is essentially the CURLOPT_SSL_VERIFYPEER option of the Curl library. See the curl_easy_setopt() man page for details on this, but essentially it means that the client does not authenticate the server's certificate of identity -- it just believes whatever the server says. You may want to use -curlnoverifyhost as well. Since you're not authenticating the server's identity, there's not much sense in checking it. This option causes xmlrpc to default to using the Curl XML transport. You may not specify any other transport.

-curlnoverifyhost

This option gives the "no_ssl_verifyhost" option for the Curl XML transport, which is essentially the CURLOPT_SSL_VERIFYHOST option of the Curl library. See the curl_easy_setopt() man page for details on this, but essentially it means that the client does not verify the server's identity. It just assumes that if the server answers the IP address of the server as indicated by the URL (probably via host name), then it's the intended server. You may want to use -curlnoverifypeer as well. As long as you don't care who the server says it is, there's no point in authenticating its identity. This option causes xmlrpc to default to using the Curl XML transport. You may not specify any other transport.

EXAMPLES¶

$ xmlrpc http://localhost:8080/RPC2 sample.add i/3 i/5

Result: Integer: 8

$ xmlrpc localhost:8080 sample.add i/3 i/5

Result: Integer: 8

$ xmlrpc http://xmlrpc.example.com/~bryanh echostring "s/This is a string"

Result: String: This is a string

$ xmlrpc http://xmlrpc.example.com/~bryanh echostring "This is a string in shortcut syntax"

Result: String: This is a string in shortcut syntax

$ xmlrpc http://xmlrpc.example.com sample.add i/3 i/5 -transport=curl -curlinterface=eth1 -username=bryanh -password=passw0rd

Result: Integer: 8

LIMITATIONS¶

If you run xmlrpc in an environment in which programs get their arguments encoded some way other than UTF-8, xmlrpc will generate garbage for the XML-RPC call and display garbage for the XML-RPC response. Typically, you control this aspect of the environment with a LANG environment variable. One safe value for LANG is "C".
