TelNot

TelNot: The Telnet server that's not quite right. Hopefully confusing to blackhats and amusing to geeks.

Demo

This animation demonstrates how it looks from the client's side - showing how it sends colorful ANSI text files byte-by-byte with random delays. Yes, it is a feature, not a bug.

Features

• Simulates a Telnet server
• Sends colorful ANSI text files byte-by-byte with random delays
• Supports both Linux (epoll) and macOS/BSD (kqueue) systems
• Uses non-blocking I/O and an event-driven architecture

Setup

1. Clone the repository:

   git clone https://github.com/tzatko/telnot.git
   

2. Navigate to the TelNot directory:

   cd telnot
   

3. Compile the project:

   make
   

Running on Linux without root privileges

To allow TelNot to bind to port 23 without running as root, you can use the setcap command to add the necessary capability:

sudo setcap cap_net_bind_service=+ep ./TelNot

Contributing

ANSI & ASCII Art

• We want cool ANSI & ASCII art
• Must look good on modern terminals. DOS codepage block art doesn't work quete right.

Credit

Currently using art from NNBnh's ansi project. Thanks!
