<h2><a name="telnet">Telnet</a></h2>
|
|
<h3>Description</h3>
|
|
Task to automate a remote telnet session. The task uses nested <read> to indicate strings to wait for, and <write> tags to specify text to send.
|
|
|
|
<p>If you do specify a userid and password, the system will assume a common unix prompt to wait on. This behavior can be easily over-ridden.</p>
|
|

<h3>Examples</h3>
|
|
A simple example of connecting to a server and running a command. This assumes a prompt of "ogin:" for the userid, and a prompt of "assword:" for the password.
|
|
<blockquote><pre>
|
|
<telnet userid="bob" password="badpass" server="localhost">
|
|
<read>/home/bob</read>
|
|
<write>ls</write>
|
|
<read string="/home/bob"/>
|
|
</telnet>
|
|
</pre></blockquote>
|
|
|
|
This task can be rewritten as:
|
|
<blockquote><pre>
|
|
<telnet server="localhost">
|
|
<read>ogin:</read>
|
|
<write>bob</write>
|
|
<read>assword:</read>
|
|
<write>badpass</write>
|
|
<read>/home/bob</read>
|
|
<write>ls</write>
|
|
<read>/home/bob</read>
|
|
</telnet>
|
|
</pre></blockquote>
|
|
|
|
A timeout can be specified at the <telnet> level or at the <read> level. This will connect, issue a sleep command that is suppressed from displaying and wait 10 seconds before quitting.
|
|
<blockquote><pre>
|
|
<telnet userid="bob" password="badpass" server="localhost" timeout="20">
|
|
<read>/home/bob</read>
|
|
<write echo="false">sleep 15</write>
|
|
<read timeout="10">/home/bob</read>
|
|
</telnet>
|
|
</pre></blockquote>
|
|
|
|
The task can be used with other ports as well:
|
|
<blockquote><pre>
|
|
<telnet port="80" server="localhost" timeout="20">
|
|
<read/>
|
|
<write>GET / http/0.9</write>
|
|
<write/>
|
|
<read timeout="10">&lt;/HTML&gt;</read>
|
|
</telnet>
|
|
</pre></blockquote>
