<h3>Examples</h3>
<p><b>Run a command on a remote machine using password authentication</b></p>
<pre>
&lt;sshexec host=&quot;somehost&quot;
username=&quot;dude&quot;
password=&quot;yo&quot;
command=&quot;touch somefile&quot;/&gt;
</pre>
<p><b>Run a command on a remote machine using key authentication</b></p>
<pre>
&lt;sshexec host=&quot;somehost&quot;
username=&quot;dude&quot;
keyfile=&quot;${user.home}/.ssh/id_dsa&quot;
passphrase=&quot;yo its a secret&quot;
command=&quot;touch somefile&quot;/&gt;
</pre>
<p><b>Run a command on a remote machine using key authentication with no passphrase</b></p>
<pre>
&lt;sshexec host=&quot;somehost&quot;
username=&quot;dude&quot;
keyfile=&quot;${user.home}/.ssh/id_dsa&quot;
command=&quot;touch somefile&quot;/&gt;
</pre>
<p><b>Run a set of commands from a command resource (file) on a remote machine using key authentication with no passphrase</b></p>
<pre>
&lt;sshexec host=&quot;somehost&quot;
username=&quot;dude&quot;
keyfile=&quot;${user.home}/.ssh/id_dsa&quot;
commandResource=&quot;to_run&quot;/&gt;
</pre>
<p><strong>Security Note:</strong> Hard coding passwords and/or usernames
in sshexec task can be a serious security hole. Consider using variable
substitution and include the password on the command line. For example:<br>
<pre>
&lt;sshexec host=&quot;somehost&quot;
username=&quot;${username}&quot;
password=&quot;${password}&quot;
command=&quot;touch somefile&quot;/&gt;
</pre>
Invoke ant with the following command line:
<pre>
ant -Dusername=me -Dpassword=mypassword target1 target2
</pre>
