ssh

A lightweight package to execute commands over an SSH connection

You can execute an SSH command like this:

Ssh::create('user', 'host')->execute('your favorite command');

It will return an instance of Symfony's Process.

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

You can install the package via composer:

composer require spatie/ssh

Usage

You can execute an SSH command like this:

$process = Ssh::create('user', 'example.com')->execute('your favorite command');

It will return an instance of Symfony's Process.

If you don't want to wait until the execute commands complete, you can call executeAsync

$process = Ssh::create('user', 'example.com')->executeAsync('your favorite command');

Getting the result of a command

To check if your command ran ok

$process->isSuccessful();

This is how you can get the output

$process->getOutput();

Running multiple commands

To run multiple commands pass an array to the execute method.

$process = Ssh::create('user', 'example.com')->execute([
   'first command',
   'second command',
]);

Choosing a port

You can choose a port by passing it to the constructor.

$port = 123;

Ssh::create('user', 'host', $port);

Alternatively you can use the usePort function:

Ssh::create('user', 'host')->usePort($port);

Using a password

You can use the constructor to specify a password to use.

Ssh::create('user', 'host', port, 'password');

Alternatively you can use the usePassword function:

Ssh::create('user', 'host')->usePassword('password');

Please make sure to have the sshpass package installed on the local system, otherwise it will silently fail.

Setting a timeout

You can set a timeout for the command.

Ssh::create('user', 'host')->setTimeout(100);

Specifying a jump host

If using a jump/proxy/bastion host, the useJumpHost function allows you to set the jump hosts details:

Ssh::create('user', 'host')->useJumpHost("$jumpuser@$jumphost:$jumpport");

Using SSH multiplexing

If making many connections to the same host, SSH multiplexing enables re-using one TCP connection. Call useMultiplexing function to set control master options:

Ssh::create('user', 'host')->useMultiplexing($controlPath, $controlPersist);

// Ssh::create('user', 'host')->useMultiplexing('/home/.ssh/control_masters/%C', '15m');

Specifying the private key to use

You can use usePrivateKey to specify a path to a private SSH key to use.

Ssh::create('user', 'host')->usePrivateKey('/home/user/.ssh/id_rsa');

Disable Strict host key checking

By default, strict host key checking is enabled. You can disable strict host key checking using disableStrictHostKeyChecking.

Ssh::create('user', 'host')->disableStrictHostKeyChecking();

Enable quiet mode

By default, the quiet mode is disabled. You can enable quiet mode using enableQuietMode.

Ssh::create('user', 'host')->enableQuietMode();

Disable Password Authentication

By default, the password authentication is enabled. You can disable password authentication using disablePasswordAuthentication.

Ssh::create('user', 'host')->disablePasswordAuthentication();

Uploading & downloading files and directories

You can upload files & directories to a host using:

Ssh::create('user', 'host')->upload('path/to/local/file', 'path/to/host/file');

Or download them:

Ssh::create('user', 'host')->download('path/to/host/file', 'path/to/local/file');

Under the hood the process will use scp.

Modifying the Symfony process

Behind the scenes all commands will be performed using Symfonys Process.

You can configure to the Process by using the configureProcess method. Here's an example where we disable the timeout.

Ssh::create('user', 'host')->configureProcess(fn (Process $process) => $process->setTimeout(null));

Immediately responding to output

You can get notified whenever your command produces output by passing a closure to onOutput.

Ssh::create('user', 'host')->onOutput(function($type, $line) {echo $line;})->execute('whoami');

Whenever there is output that closure will get called with two parameters:

• type: this can be Symfony\Component\Process\Process::OUT for regular output and Symfony\Component\Process\Process::ERR for error output
• line: the output itself

Windows Target

If your target is a Windows machine, use the onWindows method.

Ssh::create('user', 'host')->onWindows()->execute('dir');

By default this package pipes your commands to bash on the remote host. On Windows the remote shell is cmd.exe, which handles input differently and always reports a successful exit code, even when a command fails. The onWindows method passes your commands as an argument to ssh instead, so cmd.exe runs them through cmd.exe /c and their real exit code (and thus isSuccessful()) is preserved.
