(PHP ActiveX) SSH Exec (Execute Command Line)Shows how to execute a command on an SSH server and retrieve the command output.
<?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(); ?> |
