(PHP ActiveX) SSH Commands to Cisco Switch

Demonstrates how to establish an SSH session with a Cisco switch (or something similar) and send commands in a device console session.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Ssh')
$ssh = new COM("Chilkat.Ssh");

$success = $ssh->Connect('172.16.16.100',22);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Authenticate using login/password:
$success = $ssh->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Start a shell session.
$channelNum = $ssh->QuickShell();
if ($channelNum < 0) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// If the CISCO switch returns a prompt with "#", then read until we get the prompt.
// (It's not actually required that we do this, but it helps to know that all is OK at this point..)
$success = $ssh->ChannelReceiveUntilMatch($channelNum,'#','utf-8',1);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Show what we received so far:
print $ssh->getReceivedText($channelNum,'utf-8') . "\n";

// Send a "show clock" command.
$success = $ssh->ChannelSendString($channelNum,'show clock\n','utf-8');

// Read the output to the next interactive prompt.
$success = $ssh->ChannelReceiveUntilMatch($channelNum,'#','utf-8',1);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

print $ssh->getReceivedText($channelNum,'utf-8') . "\n";

// Send another command and get the output, and so on...
$success = $ssh->ChannelSendString($channelNum,'some other command\n','utf-8');
