telnet-2

Telnet-2

Telnet-2 has 2 features which the original telnet does not provide:

1. By default, it connects via Tor (expecting a local proxy to run at 127.0.0.1:9050)
2. 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.

Use

Telnet-2 [Host] [Port] [Optional Timeout]

Timeout is in seconds (the default is 10 seconds).

Tor

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:

Telnet-2 telehack.com 23
ipaddr
