Description

resource ssh2_fetch_stream ( resource channel, int streamid )

Fetches an alternate substream associated with an SSH2 channel stream identified by streamid. The SSH2 protocol currently defines only one substream, STDERR, which has a substream ID of SSH2_STREAM_STDERR (defined as 1).

Пример 1. Opening a shell and retrieving the stderr stream associated with it.


<?php

$connection = ssh2_connect('shell.example.com', 22);

ssh2_auth_password($connection, 'username', 'password');



$stdio_stream = ssh2_shell($connection);

$stderr_stream = ssh2_fetch_stream($stdio_stream, SSH2_STREAM_STDERR);

?>

In addition to the last post from Ricardo Striquer:



Simple block the stream with stream_set_blocking(), and you dont have to sleep() the script...



<?php

stdout_stream = ssh2_exec($connection, "/bin/lssss -la /tmp");



$err_stream = ssh2_fetch_stream($stdout_stream, SSH2_STREAM_STDERR);



$dio_stream = ssh2_fetch_stream($stdout_stream, SSH2_STREAM_STDDIO);



stream_set_blocking($err_stream, true);

stream_set_blocking($dio_stream, true);



$result_err = stream_get_contents($err_stream));

$result_dio = stream_get_contents($dio_stream));

?>

I got a friend using those functions and he was not able to use this ssh2_fetch_stream function. First of all I got the ssh2_shell sample by webmaster at spectreanime dot com, but this function does not work with his sample, i believe thats because he use fwrite instead of ssh2_shell or ssh2_exec to run the command.



This sample below is to run under a command line and is fully functional. note that i add the sleep as advised by webmaster at spectreanime dot com



<?php

echo "Connexion SSH ";

if (!($connection=@ssh2_connect("69.69.69.69", 22))) {

   echo "[FAILED]\n";

   exit(1);

}

echo "[OK]\nAuthentification ";



if (!@ssh2_auth_password($connection,"root","YourPassword")) {

   echo "[FAILED]\n";

   exit(1);

}

echo "[OK]\n";



$stdout_stream = ssh2_exec($connection, "/bin/lssss -la /tmp");

sleep(1);

$stderr_stream = ssh2_fetch_stream($stdout_stream, SSH2_STREAM_STDERR);



echo "Erros encontrados!\n------------\n";

while($line = fgets($stderr_stream)) { flush(); echo $line."\n"; }

echo "------------\n";



while($line = fgets($stdout_stream)) { flush(); echo $line."\n";}



fclose($stdout_stream);

?>
