Week 3 Lab 4

TASK 1:

In this task we used the windows 7 terminal command line to remotely connect to the windows 2k3 terminal and use that machine from the windows 7 machine. We did this by using the TELNET feature and by doing this we added a text file into the system and also created a new user with these commands.

1. What command can be used to show an active TELNET connection?


netstat -an | findstr 23 and the ip address connected with will say established.


2. What is the command that can be used to display files on a remote system when an administrator is connected via a TELNET session?


dir when connected to the telnet session.


3. How can you create a file on a remote system during a TELNET session?


echo with a  > in the command


4. What command can be used to determine if a remote system is running TELNET?
You use ipconfig to determine the address of the port then nmap "insert address" -p 23 to see if port 23 is open for telnet to be used.



TASK 2:




In this task we used the windows 7 terminal on the ssh port to connect to the Linux terminal by using the putty program as windows cannot use the ssh client on its own. We then used this program to connect to the Linux terminal, create a text files again and crate a user again. The main difference between the two machines is that the Linux machine is encrypted unlike the windows machine with displays information in clear text.

1. What port does Secure Shell use?

port 22

2. Is there a native SSH client or server on Microsoft Windows system?

No the system has to use imported programs such as putty to access this client.

3. What is the file in Linux that contains the password hash?

The Shadow file.

4. What are two methods that can be used for creating a file during a remote secure shell (SSH)
connection within Linux?


echo or the vi editor.



TASK 3:


In this task we used wireshark to view the connection between the terminals and see the difference between the Telnet and ssh clients. What was easily visible in the telnet communication was the password and login name used by the windows 2k3 terminal, however the ssh client wasn't in clear text and the communication was encrypted.

1. 0.61


2. There are no results on the frame contains shadow pane because the Linux system where the passwords are contained is the shadow file and so they are hidden on the ssh port. They can only be accessed directly on the Linux command system.
