netkit

[mleanz1]

Im not sure if this is the correct place to put this but i suppose its open source so ill try here!

Im trying to create a netkit lab but every time i start the lab only the first machine starts and then it all exits. Bash prints the following:
mark@mark-laptop:~/Desktop/marks_lab$ lstart

033[1m======================== Starting lab ===========================033[0m
Lab directory: /home/mark/Desktop/marks_lab
Version: 1.0

Description:
Marks Lab
033[1m=================================================================033[0m
033[1mStarting "db" with options "-q --eth0 "cd3" --hostlab=/home/mark/Desktop/marks_lab --hostwd=/home/mark/Desktop/marks_lab"... 033[0m
033[1mStarting "dns" with options "-q --eth0 "cd3" --hostlab=/home/mark/Desktop/marks_lab --hostwd=/home/mark/Desktop/marks_lab"... 033[0m
Terminated

Any advice to me it appears its been terminated by bash but how do i stop this. I have an example lab given to me by a lecture and it works fine and it is very similar to mine.
