README
Provides an object-oriented wrapper for the php ssh2 extension.
Requirements
You need PHP version 5.3+ with the SSH2 extension.
Installation
The best way to add the library to your project is using composer.
$ composer require herzult/php-ssh:~1.0
Usage
Configuration of the connection
To establish an SSH connection, you must first define its configuration. For that, create a Configuration instance with all the needed parameters.
<?php // simple configuration to connect "my-host" $configuration = new Ssh\Configuration('my-host');
The available configuration classes are:
Configuration
SshConfigFileConfiguration
Both connection configuration and public/private key authentication can be obtained from a ssh config file such as ~/.ssh/config
<?php // simple configuration to connect "my-host" $configuration = new Ssh\SshConfigFileConfiguration('/Users/username/.ssh/config', 'my-host'); $authentication = $configuration->getAuthentication('optional_passphrase', 'optional_username');
Create a session
The session is the central access point to the SSH functionality provided by the library.
<?php // ... the configuration creation $session = new Ssh\Session($configuration);
Authentication
The authentication classes allow you to authenticate over a SSH session. When you define an authentication for a session, it will authenticate on connection.
<?php $configuration = new Ssh\Configuration('myhost'); $authentication = new Ssh\Authentication\Password('John', 's3cr3t'); $session = new Session($configuration, $authentication);
The available authentication are:
None
for username based authenticationPassword
for password authenticationPublicKeyFile
to authenticate using a public keyHostBasedFile
to authenticate using a public hostkeyAgent
to authenticate using an ssh-agent
Authentication from SshConfigFileConfiguration
If you use an ssh config file you can load your authentication and configuration from it as follows:
<?php $configuration = new Ssh\SshConfigFileConfiguration('~/.ssh/config', 'my-host'); $session = new Session($configuration, $configuration->getAuthentication());
This will pick up your public and private keys from your config file Host and Identity declarations.
Subsystems
Once you are authenticated over a SSH session, you can use the subsystems.
Sftp
You can easily access the sftp subsystem of a session using the getSftp()
method:
<?php // the session creation $sftp = $session->getSftp();
See the Ssh\Sftp
class for more details on the available methods.
Publickey
The session also provides the getPublickey()
method to access the publickey subsystem:
<?php // ... the session creation $publickey = $session->getPublickey();
See the Ssh\Publickey
class for more details on the available methods.
Exec
The session provides the getExec()
method to access the exec subsystem
<?php // ... the session creation $exec = $session->getExec(); echo $exec->run('ls -lah');
See the Ssh\Exec
class for more details.
