Level Goal
The goal of this level is for you to log into the game using SSH. The host to which you need to connect is bandit.labs.overthewire.org, on port 2220. The username is bandit0 and the password is bandit0. Once logged in, go to the Level 1 page to find out how to beat Level 1.

So lets first connect to the bandit0 user with the ssh command.
ssh bandit0@bandit.labs.overthewire.org -p 220

Lets do an ‘ls -la’ to find all files in the current directory. There is a readme file. Now see the contents of this file we can use cat.
ls -la
cat readme

there is the password.
