| 11 | <h2><a name="telnet">Telnet</a></h2>
|
|---|
| 12 | <h3>Description</h3>
|
|---|
| 13 | Task to automate a remote telnet session. The task uses
|
|---|
| 14 | nested <tt><read></tt> to indicate strings to wait for, and
|
|---|
| 15 | <tt><write></tt> tags to specify text to send.
|
|---|
| 16 |
|
|---|
| 17 | <p>If you do specify a userid and password, the system will
|
|---|
| 18 | assume a common unix prompt to wait on. This behavior can be easily over-ridden.</p>
|
|---|
| 19 | <p><b>Note:</b> This task depends on external libraries not included in the Ant distribution.
|
|---|
| 20 | See <a href="../install.html#librarydependencies">Library Dependencies</a> for more information.</p>

| 60 | <h3><a name="nested">Nested Elements</a></h3>
|
|---|
| 61 | The commands to send to the server, and responses to wait for, are
|
|---|
| 62 | described as nested elements.
|
|---|
| 63 |
|
|---|
| 64 | <h4>read</h4>
|
|---|
| 65 |
|
|---|
| 66 | <p>declare (as a text child of this element) a string to wait for.
|
|---|
| 67 | The element supports the timeout attribute, which overrides any
|
|---|
| 68 | timeout specified for the task as a whole. It also has a <tt>string</tt>
|
|---|
| 69 | attribute, which is an alternative to specifying the string as
|
|---|
| 70 | a text element.
|
|---|
| 71 | </p>
|
|---|
| 72 | <i>Always declare an opening and closing
|
|---|
| 73 | <code><read></code> element to ensure that statements are not sent before
|
|---|
| 74 | the connection is ready, and that the connection is not broken before
|
|---|
| 75 | the final command has completed.
|
|---|
| 76 | </i>
|
|---|
| 77 | <h4>write</h4>
|
|---|
| 78 |
|
|---|
| 79 | <p>describes the text to send to the server. The <tt>echo</tt> boolean
|
|---|
| 80 | attribute controls whether the string is echoed to the local log;
|
|---|
| 81 | this is "true" by default
|
|---|
| 82 | </p>
|
|---|
| 83 | <h3>Examples</h3>
|
|---|
| 84 | A simple example of connecting to a server and running a command. This assumes
|
|---|
| 85 | a prompt of "ogin:" for the userid, and a prompt of "assword:"
|
|---|
| 86 | for the password.
|
|---|
| 87 |
|
|---|
| 88 | <blockquote><pre>
|
|---|
| 89 | <telnet userid="bob" password="badpass" server="localhost">
|
|---|
| 90 | <read>/home/bob</read>
|
|---|
| 91 | <write>ls</write>
|
|---|
| 92 | <read string="/home/bob"/>
|
|---|
| 93 | </telnet>
|
|---|
| 94 | </pre></blockquote>
|
|---|
| 95 |
|
|---|
| 96 | This task can be rewritten as:
|
|---|
| 97 | <blockquote><pre>
|
|---|
| 98 | <telnet server="localhost">
|
|---|
| 99 | <read>ogin:</read>
|
|---|
| 100 | <write>bob</write>
|
|---|
| 101 | <read>assword:</read>
|
|---|
| 102 | <write>badpass</write>
|
|---|
| 103 | <read>/home/bob</read>
|
|---|
| 104 | <write>ls</write>
|
|---|
| 105 | <read>/home/bob</read>
|
|---|
| 106 | </telnet>
|
|---|
| 107 | </pre></blockquote>
|
|---|
| 108 |
|
|---|
| 109 | A timeout can be specified at the <code><telnet></code> level or at the <code><read></code> level.
|
|---|
| 110 | This will connect, issue a sleep command that is suppressed from displaying and wait
|
|---|
| 111 | 10 seconds before quitting.
|
|---|
| 112 | <blockquote><pre>
|
|---|
| 113 | <telnet userid="bob" password="badpass" server="localhost" timeout="20">
|
|---|
| 114 | <read>/home/bob</read>
|
|---|
| 115 | <write echo="false">sleep 15</write>
|
|---|
| 116 | <read timeout="10">/home/bob</read>
|
|---|
| 117 | </telnet>
|
|---|
| 118 | </pre></blockquote>
|
|---|
| 119 |
|
|---|
| 120 | The task can be used with other ports as well:
|
|---|
| 121 | <blockquote><pre>
|
|---|
| 122 | <telnet port="80" server="localhost" timeout="20">
|
|---|
| 123 | <read/>
|
|---|
| 124 | <write>GET / http/0.9</write>
|
|---|
| 125 | <write/>
|
|---|
| 126 | <read timeout="10">&lt;/HTML&gt;</read>
|
|---|
| 127 | </telnet>
|
|---|
| 128 | </pre></blockquote>
|
|---|
| 129 | <p>
|
|---|
| 130 | To use this task against the WinNT telnet service, you need to configure the service to use
|
|---|
| 131 | classic authentication rather than NTLM negotiated authentication.
|
|---|
| 132 | This can be done in the Telnet Server Admin app:
|
|---|
| 133 | select "display/change registry settings", then "NTLM", then set the value of NTLM to 1.
