Level goal

The password for the next level is stored in a file readme in the homedirectory. Unfortunately, someone has modified .bashrc to log you out when you log in with SSH.

Login

ssh bandit18@bandit.labs.overthewire.org -p 2220
x2gLTTjFwMOhQ8oWNbMN362QKxfRqGlO

Doc

ssh (1)              - OpenSSH remote login client

Solution

This is a very easy sollution just like the one from the previous level. Since you get logged out right after logging in you can`t really do much since you can`t run any commands right? Well you could just pass the output of echo “cat readme” into the ssh login and it will cat the required file readme right at the start, therefore you don`t need to actually do anything in the terminal yourself.

Pseudo-terminal will not be allocated because stdin is not a terminal.
