CNT5605 - 2014 Fall
Assignment 2
Due Wednesday, October 22 Monday, October 27

Part 1

Your assignment is to again log into using ssh over port 40053. The username is your last name. You should notice that things have changed considerably on the machine. I would like for you to analyze what you are now seeing, compare it to what you saw previously, and detail both the differences and your speculation as to what has changed.

Part 2

Now log into using ssh over port 40053. The username is again your last name, and I have installed the working public key that you used in the previous assignment.

For instance, when I did this it looked like:

$ ssh -p 40053 -i ~/.ssh/cnt5605-id_rsa test@
Linux li795-74 3.15.4-x86_64-linode45 #1 SMP Mon Jul 7 08:42:36 EDT 2014 x86_64

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.

To show that you succeeded, please again create in your home directory a file named "dekita". Inside that file, identify the server you have logged into. While you are free to use whatever you would like here, there are some reasonably standard ways to describe systems, and in particular, your information should certainly be different than your description of

Part 3: Extra credit

Again, for extra credit, send email to "" but this time from the remote machine at

You can use the return email address "" for your email since the email server in Computer Science wants you to use a legitimate domain name associated with your email, and won't deliver it without something (you might want to CC yourself, just to see if you get it.) For a subject line, please include the word "ni-kai dekita", and for the body of the message, describe how you managed to send the email.

A printed journal is due for this assignment at the beginning of class on Wednesday. It only has to cover part 1, however, though you are welcome to write also about parts 2 or 3 if you like.
