pull remote from github with phpseclib

Question

I am trying to auto update a website from remote git repo. As it's on a shared hosting i use a webhook on github & phpseclib 1.0. Here is my code:

$ssh = new Net_SSH2(SITE_DOMAIN);
$key = new Crypt_RSA();
$key->loadKey(file_get_contents('/home/'.SSH_USERNAME.'/.ssh/'.KEYPAIR_NAME));
if (!$ssh->login(SSH_USERNAME, $key)) {
 throw new Exception('Failed to login');
 exit('Login Failed');
}
echo $ssh->write("cd ~/source\n");
echo $ssh->write("git pull origin master\n");

the git command won't run. but when i do a git pull manually from terminal it works Thanks for your help

Answer 1

From your code:

echo $ssh->write("cd ~/source\n");
echo $ssh->write("git pull origin master\n");

Usually with interactive shells you need to wait for the prompt before you send the next command. Try something like this:

$ssh->read('#[prompt]#');
echo $ssh->write("cd ~/source\n");
$ssh->read('#[prompt]#');
echo $ssh->write("git pull origin master\n");

Sometimes identifying what the prompt is is easy - sometimes it's less so. Like if the prompt has colored text in it that would mean that the prompt is not what you think it is.

Here is the solution that worked for me

$ssh->setTimeout(2);
echo $ssh->write("cd ~/source\n");
$ssh->read();
echo $ssh->write("git pull origin master\n");
