(PHP Extension) SSH to Cisco Switch - Processing "More" ResponsesDemonstrates connecting to a Cisco switch, running a command to enable privileged mode, then running a command to get a paged response requiring the SPACE char to be sent to process "--More--".
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $ssh = new CkSsh(); $success = $ssh->Connect('SSH_SERVER_DOMAIN_OR_IP_ADDRESS',22); if ($success != true) { print $ssh->lastErrorText() .

"\n"; exit; } // Show what we received so far: print $ssh->getReceivedText($channelNum,'utf-8') . "\n"; // Send the "ena" command to enable privileged mode. // (For the Cisco switch, terminate command with a single CR char.) $success = $ssh->ChannelSendString($channelNum,'ena\r','utf-8'); // Assume success for this example to make it shorter.. // Read to the "Password:" prompt. $success = $ssh->ChannelReceiveUntilMatch($channelNum,'Password:','utf-8',true); if ($success != true) { print $ssh->lastErrorText() .
