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', 'host')->execute('your favorite command');

It will return an instance of Symfony's Process.

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', 'host')->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);

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');

Strict host key checking

By default, strict host key checking is enabled.

The host key is obtained, prior to the SSH connection, by finding and running the ssh-keyscan utility.

For more information about ssh-keyscan, use the man pages on your host system or see:

• https://man.openbsd.org/ssh-keyscan (BSD verions)
• https://linux.die.net/man/1/ssh-keyscan (GNU Linux versions)

Warning: you will not be prompted to accept the key of the host system, it will automatically be accepted. You will thus lose the design feature of SSH where a new key indicates the host system has changed.

To disable strict host key checking altogether, use disableStrictHostKeyChecking

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