Net_Telnet provides a PHP implementation of the TELNET protocol.
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
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();
?>

There is currently no packaging for PEAR or otherwise.
There's an Issue tracker on the github page if you want to report bugs.
I'll look at making this a full PEAR package eventually, but it's a standalone project at the moment.
