Secure Shell 2

ssh2.shell:// ssh2.exec:// ssh2.tunnel:// ssh2.sftp:// ssh2.scp:// PHP 4.3.0 and up (PECL)

  • ssh2.shell://user:pass@example.com:22/xterm
  • ssh2.exec://user:pass@example.com:22/usr/local/bin/somecmd
  • ssh2.tunnel://user:pass@example.com:22/192.168.0.1:14
  • ssh2.sftp://user:pass@example.com:22/path/to/filename

Замечание: This wrapper is not enabled by default In order to use the ssh2.*:// wrappers you must install the » SSH2 extension available from » PECL.

In addition to accepting traditional URI login details, the ssh2 wrappers will also reuse open connections by passing the connection resource in the host portion of the URL.

Пример #1 Opening a stream from an active connection

<?php
$session 
ssh2_connect('example.com'22);
ssh2_auth_pubkey_file($session'username''/home/username/.ssh/id_rsa.pub',
                                            
'/home/username/.ssh/id_rsa''secret');
$stream fopen("ssh2.tunnel://$session/remote.example.com:1234"'r');
?>

Be aware that opendir is currently broken on sftp root directories, but you can work around it by appending a dot. See https://bugs.php.net/bug.php?id=64169 and http://stackoverflow.com/a/16238476/69173.

The "password" context option can also be used to provide the passphrase for the keyfile supplied by "privkey_file" and "pubkey_file".

Encrypted keys may not work unless you build libssh2 against openssl. (It only worked for me on Debian Wheezy once I recompiled the library).

Please beware of a PHP bug, noted by thomas at gielfeldt dot dk, that you must intval() the connection variable before putting it in the connection string :

<?php
$connection 
ssh2_connect('shell.example.com'22);
ssh2_auth_password($connection'username''password');
$sftp ssh2_sftp($connection);
// See: https://bugs.php.net/bug.php?id=73597
$stream fopen("ssh2.sftp://" intval($sftp) . "/path/to/file"'r');
?>
