Hey I am in a network that has a certain amount of servers.

On port 80, one of them can be used as a proxy to connect to the internet, but I would like to find out if it is possible for the others that I found on Zenmap, too. However, there are too many servers to try out all them +doing that on different ports/settings.

Is there any script/program I could use for that? I have win7 64bit, Ubuntu 64bit, OSX, iOS and Android systems to let the program run on, available.

The program is called nmap, it can do an amazing number of things, exists for Windows/Unix/Linux. The command you want to try is:

  nmap -p 80 192.168.0.0/24

(modify the network as per your needs). This command will test port 80 to see whether it is open. nmap can do an amazing number of things, have fun studying what you can discover with it.

Edit:

Actually, nmap can also scan not just port 80, but the function of proxying:

  nmap --script http-open-proxy.nse --script-args proxy.url=<url>

which can of course be easily scripted. You can find the reference here.

Thanks a lot for your answer, but this will just check, if the server replies positively to that port-request. What I want to know is, if there is an actual open internet connection behind the servers. –  user2875404 Jan 13 at 18:06
    
@user2875404 What do you mean? If there is an actual proxy program running on the pc in question? –  MariusMatutiae Jan 13 at 18:07
    
Each of these servers I found have 80 as a common open port. But having the port open does not automatically mean, I can get internet through them by setting this address as a proxy. That's why I need to check all of them (so far I figured out all that for one of them) –  user2875404 Jan 13 at 18:11
    
@user2875404 See my edit. –  MariusMatutiae Jan 13 at 18:22
