title: Can't connect to remote server on specific port
body: <p>I need to make a TCP/IP socket server in PHP.
  So I downloaded an example from <a href="http://www.php.net/manual/en/sockets.examples.php" rel="nofollow">php.net</a> and tried it on my own machine (changed default script socket ip to 127.0.0.1). I opened it from web-browser (because I use XAMMP system, so I can't do a background working shell script), connected to 127.0.0.1:8175 by Telnet and it worked fine!
  But now I have a problem:</p>
  
  <p>I uploaded that script to remote server, opened port 8175 on the router and could not connect to the remote port from my computer. But I still can connect to the web and ssh ports on that server.
  Any ideas?</p>
  
  <p>If I asked that question in a wrong place, just say it. And... Sorry for my bad English.</p>
