Net_Telnet

Net_Telnet provides a PHP implementation of the TELNET protocol.

RFCs

Net_Telnet implements the following:

• RFC 854 TELNET Protocol Specification
• RFC 855 TELNET Option Specification
• RFC 856 TELNET Binary Transmission
• RFC 857 TELNET ECHO Option
• RFC 858 TELNET SUPPRESS GO AHEAD option
• RFC 860 TELNET TIMING MARK option

Use

Net_Telnet has been used for short-running scripts, eg. to login to a device and check status or reboot; I don't know how it would fair in handling long-running connections or in more complex applications. Also it has only been used as a TELNET client, the initial options and other default behavior would need to be reviewed to operate correctly as a TELNET server (and need to add a listen() function).

<?php
require_once "Net/Telnet.php";

try {
    $t = new Net_Telnet('10.15.20.25');
    $t->connect();

    echo $t->login( array(
        'login_prompt'  => '',
        'login_success' => '',
        'login_fail'    => '% Access denied',
        'login'         => '',
        'password'      => 'cisco_password',
        'prompt'        => 'Cisco>',
        )
    );

    echo $t->cmd('show version');

    $t->disconnect();

    echo $t->get_data();
    echo "\n";
}
catch (Exception $e) {
    echo "Caught Exception ('{$e->getMessage()}')\n{$e}\n";
}

exit();
?>

I'll look at making this a full PEAR package eventually, but it's a standalone project at the moment.
