#- GO THROUGH CODE AND DO COMMENTING, SPACING, MAKE WHAT'S PRINTED TO COMMANDLINE PRETTIER
#- ADD FLATFILE GAME SAVES LIKE IN TEXT RPG - ASK FOR PLAYER NAME AT START AND BASE THEIR LOCAL SHELL NAME AND EMAIL ADDRESS OFF OF IT: VARIABLE 'NAME' IS ALREADY CREATED
#- UPDATE 'EXIT' COMMAND TO SUPPORT CUSTOM NAMES ^^^
#- FINISH SCP - TIDY UP AND ADD FACT (FOR REAL SYNTAX)
#- TIDY EMAIL INBOX AND SENTBOXES INTO TABLES. WHEN PRINTING THE TABLE, USE THE LENGTH OF THE VARIABLES TO DECIDE HOW MANY SPACES TO ADD
#- COME UP WITH MORE EFFICIENT WAY FOR RECIEVING TIPS - I.E EINBOX AND EOPEN. MERGE TIP VARIABLE WITH EMAILS VARIABLE, AND ADD A NEW VALUE TO DETERMINE IF IT'S A NORMAL EMAIL OR A TIP???? MAYBE?????

I'm sorry, but If you're cheating at this stage, this may not be the game for you.
Firstly, we can run the command 'ls' to find out what files are on the current server. There's only one
file available to us on this server at the moment, and it's called location1.txt. So, let's run the
command 'cat location1.txt' to read it. The file says that we can access the first server in the
BioInnovations network with the IP address 97.73.9.646, and also that there is a new employee at
BioInnovations called Jeff, who hasen't yet changed his password from the default. So, let's run the
command 'ssh jeff@97.73.9.646' to access the server. You will now be prompted for Jeff's password, and
I don't doubt that's the bit you're stuck on. Now, there are quite a few default passwords which this
could have been, (e.g password, changeme, default, 0000 etc etc), and the answer (by guessing) is password.
===================================
Run the command 'ssh jeff@97.73.9.646 and enter password as the password when prompted.""")

I'm sorry, but If you're cheating at this stage, this may not be the game for you.
Firstly, let's launch Jeff's email client with the 'email' command. Upon using the email command
'inbox', we are shown an email called 10/02/2015, which is obviously also the date it was recieved.
The email can be opened by typing 'cat 10/02/2015'. When we read the email Jeff recieved on the 10th
of february, we discover some interesting information. Firstly, there is someone working in Senior
Management name J. Turner, he may be important later. We're also told that Jeff has an account on the main
company server with the same user name, Jeff. The password is supposedly the birth date of their most
recent client, one Mr. A. Johnstone. Let's close out of the email client with 'exit' and then see what
files Jeff has stored on his local drive with 'ls'. There's a file called 'recent_transactions.txt',
but unfortunately Jeff doesnt have the appropriate permissions to open this file. So, let's go into
the other file named 'client_profiles.txt' with 'cat client_profiles.txt'. Great! This file shows us
information on all of the clients BioInnovations exchanged goods and money with recently. The 1st
entry in the list is Andrew Johnstone, and the file tells us that his date of birth is 04/11/1958.
This will be the password.
Ok, so we have the user name and password, but we still don't know the address of the server... Let's go
back into the email client with 'email' and run 'inbox' again. There's another email from the 3rd of February,
so let's open that up with 'cat 11/02/2015'. Now we're getting somewhere, this email contains the server
address! It's 12.89.5.309. Easy peasy.
===================================
What a shame Jeff has broken his phone... Anyway, the answer to this level is to SSH into the server
12.89.5.309 with username Jeff and password 04/11/1958 In other words, run this command:
'ssh jeff@12.89.5.309', and then type 04/11/1958 once the password field appears.""")
