ActiveX for 32-bit and 64-bit Windows

Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// 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");

// Connect to an SSH server:

// Hostname may be an IP address or hostname:
$hostname = '192.168.1.108';
$port = 22;

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

// Wait a max of 5 seconds when reading responses..
$ssh->IdleTimeoutMs = 5000;

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

// Open a session channel.  (It is possible to have multiple
// session channels open simultaneously.)

$channelNum = $ssh->OpenSessionChannel();
if ($channelNum < 0) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// The SendReqExec method starts a command on the remote
// server.   The syntax of the command string depends on the
// default shell used on the remote server to run the command.
// On Windows systems it is CMD.EXE.  On UNIX/Linux
// systems the user's default shell is typically defined in /etc/password.

// Here are some examples of command lines for <b>Windows SSH servers</b>:

// Get a directory listing:
$cmd1 = 'dir';

// Do a nameserver lookup:
$cmd2 = 'nslookup chilkatsoft.com';

// List a specific directory.  Given that the shell is CMD.EXE, backslashes must
// be used:
$cmd3 = 'dir \\temp';

// Execute a sequence of commands.  The syntax for CMD.EXE may be found
// here: http://technet.microsoft.com/en-us/library/bb490880.aspx.  Notice how the commands
// are separated by "&&" and the entire command must be enclosed in quotes:
$cmd4 = '\'cd \\temp&&dir\'';

// Here are two examples of command lines for <b>Linux/UNIX SSH servers</b>:

// Get a directory listing:
$cmd5 = 'ls -l /tmp';

// Run a series of commands (syntax may depend on your default shell):
$cmd6 = 'cd /etc; ls -la';

// Request a directory listing on the remote server:
// If your server is Windows, change the string from "ls" to "dir"
$success = $ssh->SendReqExec($channelNum,'ls');
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Call ChannelReceiveToClose to read 
// output until the server's corresponding "channel close" is received.
$success = $ssh->ChannelReceiveToClose($channelNum);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Let's pickup the accumulated output of the command:
$cmdOutput = $ssh->getReceivedText($channelNum,'ansi');
if ($ssh->LastMethodSuccess != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Display the remote shell's command output:
print $cmdOutput . "\n";

// Disconnect
$ssh->Disconnect();
