The next level asks us to connect to port 30000 on localhost and submit the password for the current level. The telnet command was available, so it seemed to be the quickest method of getting this done.

bandit14@bandit:~$ cd /etc/bandit_pass/
bandit14@bandit:/etc/bandit_pass$ cat bandit14
XXXXXXXXXXXX (actual password not shown)
bandit14@bandit:/etc/bandit_pass$
bandit14@bandit:/etc/bandit_pass$ telnet 127.0.0.1 30000
Trying 127.0.0.1...
