Host: bandit.labs.overthewire.org
Port: 2220
Level 12
ssh bandit12@bandit.labs.overthewire.org -p 2220

Objective:
The password for the next level is stored in the file data.txt, which is a hexdump of a file that has been repeatedly compressed. For this level it may be useful to create a directory under /tmp in which you can work using mkdir. For example: mkdir /tmp/myname123. Then copy the datafile using cp, and rename it using mv (read the manpages!)
