note 121969 added to function.ssh2-connect

This page is out of date. Any of the SHA-1 in the Key Exchange Methods in the kex section should be discarded, due to Logjam (https://weakdh.org/logjam.html). If you continue to use them, connects will result in the following warning: "Warning: ssh2_connect(): Error starting up SSH connection(-5): Unable to exchange encryption keys in ..." The following is an example of what works. Also by removing the 'hex' section all together, results in libssl (https://libssh2.org/) falling back to discovering which is the strongest cipher to authenticate with. <?php if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist"); function ssh2_debug($message, $language, $always_display) { printf("%s %s %s\n",$message,$language,$always_display); } /* Notify the user if the server terminates the connection */ function my_ssh_disconnect($reason, $message, $language) { printf("Server disconnected with reason code [%d] and message: %s\n", $reason, $message); } $methods = array( 'hostkey'=>'ssh-rsa,ssh-dss', // 'kex' => 'diffie-hellman-group-exchange-sha256', 'client_to_server' => array( 'crypt' => 'aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,3des-cbc,blowfish-cbc', 'comp' => 'none'), 'server_to_client' => array( 'crypt' => 'aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,3des-cbc,blowfish-cbc', 'comp' => 'none')); $callbacks = array('disconnect' => 'my_ssh_disconnect'); foreach (array('192.168.1.1') as $host) { $connection = ssh2_connect($host, 22, $methods, $callbacks); if (!$connection) die("Connection failed:"); ssh2_auth_password($connection, 'user', 'my_password') or die("Unable to authenticate"); $stream = ssh2_exec($connection, 'free -m'); stream_set_blocking($stream, true); $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO); echo stream_get_contents($stream_out); } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 73.160.147.229 ---- Manual Page -- http://php.net/manual/en/function.ssh2-connect.php Edit -- https://master.php.net/note/edit/121969 Del: integrated -- https://master.php.net/note/delete/121969/integrated Del: useless -- https://master.php.net/note/delete/121969/useless Del: bad code -- https://master.php.net/note/delete/121969/bad+code Del: spam -- https://master.php.net/note/delete/121969/spam Del: non-english -- https://master.php.net/note/delete/121969/non-english Del: in docs -- https://master.php.net/note/delete/121969/in+docs Del: other reasons-- https://master.php.net/note/delete/121969 Reject -- https://master.php.net/note/reject/121969 Search -- https://master.php.net/manage/user-notes.php
