Telnet-2 has 2 features which the original telnet does not provide:
- By default, it connects via Tor (expecting a local proxy to run at
127.0.0.1:9050) - You can optionally define the connection timeout (default is 10s).
Both of those features can be important when investigating high-profile targets such as servers in North Korea. Using Tor helps to conceal your identity and helps to bypass IP blocking.
Telnet-2 [Host] [Port] [Optional Timeout]
Timeout is in seconds (the default is 10 seconds).
You can find the Tor Expert Bundle in the sub-directories of https://dist.torproject.org/torbrowser/. The latest Windows version is the file tor-win64-0.4.0.5.zip. Extract it and start tor.exe, which will start the proxy listening on 127.0.0.1:9050.
With the following server and command you can see which Tor exit node IP is assigned to the current circuit:
