Troubleshooting

If we are to use a terminal emulator without an X server installed or properly configured the miniedit tool will not run. This tool presents us with a GUI we can use to define our network and then it'll generate a script that brings it up for us. If we are to reroute the stdout of a VM we will need to set the $DISPLAY variable accordingly as miniedit used tkinter and it needs it to run correctly.
If there are problems when launching the scenario try to clean up the previous environment. If we exit the mininet CLI by issuing the quit everything should be deleted correctly, otherwise we can always clean it up ourselves by running:

sudo mn -c
