Findwall : Check If Your Provider Is Blocking You

FindWall is Python script that allows to understand if your network provider is limiting your access to the Internet by blocking any TCP/UDP port. In order to perform this check FindWall needs to connect a public VPS of your property. FindWall performs the following actions:

  • Connects to the VPS via SSH
  • Opens a port in listening mode
  • Tries to connect to that port from the local machine
  • Closes the port

How do you use it?

To use FindWall you just need an account on a public VPS. The account must have root access if you want to test ports in the range 1-1024. The root account is also required to automatically install the tool nc to open ports.

$ pip install -r requirements
$ python findwall.py –help
