ViewsSSH into dynamic remote server and run a command - Laravel 5.8
I'm using L 5.8 and I have a form with 3 inputs
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,

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;
});

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>
