Browser Control of VLM

Postby Scott JHU-ECE » 07 Dec 2005 13:48

Does anyone have experience (and/or thoughts and suggestions) on controlling VLM (either through the telnet or the http interface) from within a browser? I was trying to do it with PHP; which supposedly provides for a telnet connection interface, but it didn't want to connect properly. I'd imagine I could pull it off with a java applet, but I'd like to try and avoid such a cumbersome interface. Has anyone else done this?

Havn't do it with PHP, but the VLM control is simply a telnet with port 4212 by default, just write a script with socket or telnetlib if exist. I wrote one in python, so it should works with PHP....

I'm close, very close. I open the connection as follows:
$pw = 'ece';
$fp = fsockopen("128.220.81.237", 80, $errno, $errstr, 10);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: 128.220.81.237\r\n";
$out .= "\r\n";

fputs($fp, $out);

$i = 0; // Placeholder that helps the script along.

echo fgets($fp, 128); // Pasword prompt shows up here.
echo fputs($fp, "ece"); // Send the password.
echo fgets($fp, 128); // Returns wrong password from here on out :-(
echo fputs($fp, $pw);
echo fgets($fp, 128);

fclose($fp);
...and it does indeed bring up the Password: prompt. However, I can't get it to parse the password I send to it (see above). I've tried \r's and \n's at the end of the line and combinations thereof. fputs() gives the number of characters written if successful, and it does indeed spit back '3' at me, as expected. VLC's telnet interface doesn't seem to want to take it though. Any thoughts?

Hi Scott,

I don't know why you did it with port 80 and those HTTP header's code...

I did the trick by using a ethereal sniffer to "hear" all traffics between VLC server and client side, after that with Following TCP stream, you'll get all message in clair mode... so you might know what's wrong with your code... hope this helps.

cheers

Scott, did you get control through the telnet interface working from php?
I would like to do the same sort of thing...
Streaming audio and vidio from a server, controlled by a database and web site written in php - that is the plan :)

I suggest trying using remote terminal with Xp maybe that would be a better choice. I also have a question am looking to use a database to stream my files. Do youhave any suggestions on how to make one I saw that you are making one so I would like to get some pointers where I can look at some code to create one. Thanks
