Smashthestack Blowfish Level 01

In this level when we are asked to telnet to on port 6666.
When doing that we get:

san@bart:~$ nc 6666


 Crack this passwd with john the ripper
 and use the password to login with
 ssh -p 2222


We download and install john the ripper and after that we create a file like this:


We run john the ripper with that as input and it breaks it really quickly:

$ ./john smashthestack 
Loaded 1 password hash (FreeBSD MD5 [32/32])

We have the password for the second level: welcome
