telnet_scripter

Telnet passthrough program which allows you run scripts (any program using stdin/stdout), useful for playing telnet-based MUDs

How to build?

Install bazel

To build a deployable jar, run bazel build //java/com/jeffreys/telnet:TelnetScripter_deploy.jar

How to test?

To execute tests, run bazel test //javatests/com/jeffreys/telnet:all

How to execute?

java -jar TelnetScripter_deploy.jar <arguments>

• --remote_host=remote host to connect to
• --remote_port=remote port to connect to, default 23
• --local_port=local port to listen on, default 2112

You can also run out of the repo directory, bazel run //java/com/jeffreys/telnet:TelnetScript -- <arguments>

Now telnet to your localhost on the --local_port value, and you'll be connected to the --remote_host

How do you run a script?

Once you're connected to a system, you just type in the magic command #!script <script_path> and hit enter. It should launch the script file with the telnet connection as stdin and any writes to stdout will go to the telnet host.

A script can be written in any language since I/O is simply through stdin/stdout.

Here's a simple script that writes something every 5 seconds

#!bin/bash

while :
do
  sleep 5
  echo "Hi, I'm sending data!"
done

How to stop your script?

Just kill the script process in your OS. You cannot stop it via special text commands.

Why Java?

For maximum cross platform support. You can run this on Windows, Linux, Raspberry Pi, etc.
