Just like the Telnet task, it uses nested <tt><read></tt> to indicate strings to wait for, and <tt><write></tt> tags to specify text to send to the remote process. <p><b>Note:</b> This task depends on external libraries not included in the Ant distribution. See <a href="../install.html#librarydependencies">Library Dependencies</a> for more information.</p> <h3>Parameters</h3> <table border="1" cellpadding="2" cellspacing="0"> <tr> <th>Attribute</th> <th>Values</th> <th>Required</th> </tr> <tr> <td>userid</td> <td>the login id to use on the remote server.</td> <td>Yes</td> </tr> <tr> <td>password</td> <td>the login password to use on the remote server.</td> <td>Yes</td> </tr> <tr> <td>server</td> <td>the address of the remote rexec server.</td> <td>Yes</td> </tr> <tr> <td>command</td> <td>the command to execute on the remote server.</td> <td>Yes</td> </tr> <tr> <td>port</td> <td>the port number of the remote rexec server. Defaults to port 512 in BSD Unix systems.</td> <td>No</td> </tr> <tr> <td>timeout</td> <td>set a default timeout to wait for a response. Specified in seconds. Default is no timeout.</td> <td>No</td> </tr> </table> <h3><a name="nested">Nested Elements</a></h3> The input to send to the server, and responses to wait for, are described as nested elements. <h4>read</h4> <p>declare (as a text child of this element) a string to wait for. The element supports the timeout attribute, which overrides any timeout specified for the task as a whole. It also has a <tt>string</tt> attribute, which is an alternative to specifying the string as a text element. </p> <i>It is not necessary to declare a closing <read> element like for the Telnet task. The connection is not broken until the command has completed and the input stream (output of the command) is terminated. </i> <h4>write</h4> <p>describes the text to send to the server. The <tt>echo</tt> boolean attribute controls whether the string is echoed to the local log; this is "true" by default </p> <h3>Example</h3> A simple example of connecting to a server and running a command. <blockquote><pre> <rexec userid="bob" password="badpass" server="localhost" command="ls"/> </pre></blockquote> The task can be used with other ports as well: <blockquote><pre> <rexec port="80" userid="bob" password="badpass" server="localhost" command="ls"/> </pre></blockquote> <hr> <p align="center">Copyright © 2003 Apache Software Foundation.
