Bug description: proc_open Apache 1.3.27 with php 4.3.2
Apache 1.3.27 with php 4.3.2. I'm tryin to implement a way to do a 2-way
communication through telnet for my script
here's what I've found! (111.111.111.111 example ip is a unix box and it
is accepting telnet connections"
Consider this.
$failed = false; // authentication failure flag
$cmd="telnet 111.111.111.111";
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read
from
1 => array("pipe", "w"), // stdout is a pipe that the child will write
to
2 => array("pipe", "w") // stderr is a pipe that the child will write
to
);
$userID="user";
$password="password";
$process = proc_open("$cmd", $descriptorspec, $pipes);
echo $process;
if (is_resource($process)) {
fwrite($pipes[0], "$userID\r");
fwrite($pipes[0], "$password\r");
fwrite($pipes[1], "exit\r");
while(!feof($pipes[1])) {
$line = fgets($pipes[1], 1024);
$loginFailed = strpos($line, "invalid login name or password");
if ($loginFailed != false)
{ $failed = true;
// echo "FAILED LOGGING";
}
// DEBUG OUTPUT
echo $line;
echo "---<br>";
}
fclose($pipes[1]);
$return_value = proc_close($process);
echo "<br><b>command returned<b> $return_value\n";
}
The following will result in empty pipes[1]. I'm unable to get anything
out of that pipe as well the fgets just seems to hang. when i try the
same code on AIX platform it works. So i'm thinking its a bug...
