Accessing BackTrack VM

Some ways how you can access the BackTrack machine in the lab from where you have to do the actual work.

1. Command line access: ssh user@192.168.133.X
   • Default username is ""

1. X11 session redirected over SSH
   • ssh -X -C user@ 192.168.133.X
   • Now you can start programs with GUI e.g. konqueror &, firefox &. Note that it could be relatively slow.

1. VNC for graphical user interface
   • Log into BackTrack VM over SSH and start vncserver: vncserver -geometry 1280x800
   • Obviously, the geometry specifies the screen size, adjust it according to your monitor
   • When executing vncserver first time, you will be asked for a password. This password just protects access to the display of your machine. Choose password that you prefer. The password file is /home/user/.vnc/passwd. If you would like to change the password, just remove that file and start vncserver again.
   • If you need to kill any vncserver instances: vncserver -kill :1. This kills X desktop number 1.
   • On Student VM or you own computer use vncviewer to access the display: vncviewer 192.168.133.X:1. Number 1 expresses the display number.

Course Management Application

• Mission and task descriptions as well as scoreboard will be displayed over the web https://cma.ex/
  • This site is accessible only from the BackTrack machine
• Register a new user account. Username will be displayed on the scoreboard - this can be something anonymous
• First and Last Name will be used to track if you have participated in the lab - these have to be real.
• NB! Please, do not hack the scoreboard! If you find any vulnerabilities, report them to the instructor.
