SSH into dynamic remote server and run a command

The

Right now, I can SSH into a specific server with this package laravelcollective/remote": "~5.8. I required to pre configured IP, UN, PW in the config/remote.php like so :

'connections' => [ 'production' => [ 'host' => '1.1.1.1', 'username' => 'code', 'password' => '8888', 'key' => '', 'keytext' => '', 'keyphrase' => '', 'agent' => '', 'timeout' => 10, ], ],

Then, I can easily run any command(s) or even chain them

$commands = ['cd /home/code && ./runMe.sh']; SSH::run($commands, function($line) { echo $line.PHP_EOL; });

Result

My portal will connect to that server and run that command successfully, and I've verified it.

Now

I need to read it from form inputs. Is it possible to use the same plugin and dynamically setting that file remote.php ?

or

Should I start looking into something else because this is a dead end ?

Please advise,

This example require the package php-ssh2, and provide many ways to retrieve the remote shell STDOUT as a stream. It's also great to control the current machine shell and get responses.

sudo apt install php-ssh2

Or by version:

sudo apt install php7.4-ssh2

Example usage of ssh2_exec() and ssh2_fetch_stream():

<?php $ssh = ssh2_connect('192.162.68.212', 22); // Remote address ssh2_auth_password($ssh, 'root', 'XQA8DCamdEm'); // Credentials $shell = ssh2_shell($ssh, 'xterm'); // Choose remote shell $stream = ssh2_exec($ssh, 'cd /home/code && ./runMe.sh'); // Remote command stream_set_blocking($stream, true); // Wait for multiline output, till EOF $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO); // SSH2_STREAM_STDERR echo stream_get_contents($stream_out); // Print in real-time

It is possible to retrieve only the errors, this is great for monitoring only without parsing the whole output, by using the flag SSH2_STREAM_STDERR.

To write strings only to STDERR from the remote PHP, we can use:

fwrite(STDERR, "Some logs, from machine (...)\n");

Or we can pipe the errors directly in the remote shell command:

cd /home/code && ./runMe.sh 2>

You can use the config() helper here:

example config:

config([ 'remote.connections.production.host' => $request->input('hostname'), 'remote.connections.production.username' => $request->input('username'), 'remote.connections.production.password' => $request->input('password') ]);

then call:

$commands = ['cd /home/code && ./runMe.sh']; SSH::run($commands, function($line) { echo $line.PHP_EOL; });
