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
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
