Steam Locomotive

Solved by: Legend

In this challenge we were provided with a ssh credentials to get the flag, with a hint that ls command was getting mistyped accidentally.

When I connect to the ssh it was playing an animation of steam engine, sl command which is Steam Locomotive, and then when the animation was over then immediately the session was getting disconnected.

To retrieve the flag we needed to read the flag and since ssh allows direct command execution during connection we can read the flag using that.
