Port filtering
- An internet connection
Ability to detect port-based filtering if present
This test uses a predefined list of TCP ports and attempts to establish a connection to each port listening on a test-helper.
The main task involved in the experiment is:
TCP Connect Attempt to establish a TCP session on the given ports in a pseudo-random order. The results of the connecting end up in the "tcp_connect" key. (see df-005-tcpconnect.md).
We will include data following these data formats:
df-005-tcpconnect
{
"tcp_connect": [],
}where:
tcp_connectcontains a list ofdf-005-tcpconnectinstances
- If a blocking mechanism censors a particular port.
