Bricking towers and charming snakes

To access this window, you need to make a TCP connection to cparta.djul.se 31337 .

There is a (not always well working) page on this website you can use, but if you prefer the comfort of your own terminal that is recommended! And be warned: the web version may not work as expected. For example if this website crashes or gets redeployed, or if the tab is unfocused for a short while, or you are simply not blessed by dAnkan, you will be disconnected and have to start over!

This is most easily performed by invoking the tool netcat in your terminal, like so: nc cparta.djul.se 31337

(swap nc in the above command for the appropriate netcat tool on your system! Some other possible names for it are ncat or netcat)

If you are using Windows, you can download netcat from nmap.org/ncat. It should already be installed on MacOS and most linux distros, otherwise install it with your favourite or second favourite package manager.

Good luck!

Hint 1: Some tools are more appropriate than others! If you think your solution should work but doesn't, please attempt to connect via a different terminal application (e.g. WSL), or use a terminal-agnostic approach like PwnTools in Python!

You must be logged in and in a team to submit!
