Due to a lack of complete examples, here's a simple SSH2 class for connecting to a server, authenticating with public key authentication, verifying the server's fingerprint, issuing commands and reading their STDOUT and properly disconnecting. Note: You may need to make sure you commands produce output so the response can be pulled. Some people suggest that the command is not executed until you pull the response back. <?php class NiceSSH { // SSH Host private $ssh_host = 'myserver.example.com'; // SSH Port private $ssh_port = 22; // SSH Server Fingerprint private $ssh_server_fp = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; // SSH Username private $ssh_auth_user = 'username'; // SSH Public Key File private $ssh_auth_pub = '/home/username/.ssh/id_rsa.pub'; // SSH Private Key File private $ssh_auth_priv = '/home/username/.ssh/id_rsa'; // SSH Private Key Passphrase (null == no passphrase) private $ssh_auth_pass; // SSH Connection private $connection; public function connect() { if (!($this->connection = ssh2_connect($this->ssh_host, $this->ssh_port))) { throw new Exception('Cannot connect to server'); } $fingerprint = ssh2_fingerprint($this->connection, SSH2_FINGERPRINT_MD5 | SSH2_FINGERPRINT_HEX); if (strcmp($this->ssh_master_fp, $fingerprint) !== 0) { throw new Exception('Unable to verify server identity!'); } if (!ssh2_auth_pubkey_file($this->connection, $this->ssh_auth_user, $this->ssh_auth_pub, $this->ssh_auth_priv, $this->ssh_auth_pass)) { throw new Exception('Autentication rejected by server'); } } public function exec($cmd) { if (!($stream = ssh2_exec($this->connection, $cmd))) { throw new Exception('SSH command failed'); } stream_set_blocking($stream, true); $data = ""; while ($buf = fread($stream, 4096)) { $data .= $buf; } fclose($stream); return $data; } public function disconnect() { $this->exec($this->connection, 'echo "EXITING" && exit;'); $this->connection = null; } public function __destruct() { $this->disconnect(); } } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 99.9.85.218 ---- Manual Page -- http://www.php.net/manual/en/function.ssh2-connect.php Edit -- https://master.php.net/note/edit/104758 Del: integrated -- https://master.php.net/note/delete/104758/integrated Del: useless -- https://master.php.net/note/delete/104758/useless Del: bad code -- https://master.php.net/note/delete/104758/bad+code Del: spam -- https://master.php.net/note/delete/104758/spam Del: non-english -- https://master.php.net/note/delete/104758/non-english Del: in docs -- https://master.php.net/note/delete/104758/in+docs Del: other reasons-- https://master.php.net/note/delete/104758 Reject -- https://master.php.net/note/reject/104758 Search -- https://master.php.net/manage/user-notes.php
