I have installed mininet on remote server, There is no X server installed in this machine. I am not able to run xterm c0 command. gives error Error: Cannot connect to display
I want to run tests on switches using ryu. I am not able to open the controller in mininet and execute. Is there any alternative to xterm in mininet?
You need xterm if you need complex debugging as it is written in Mininet documentation.
For more complex debugging, you can start Mininet so that it spawns one or more xterms.
You can do lots of tests without xterm. For example, here is an example of adding flows to mininet switches controlled by RYU.
Mininet Walkthrough page also explains other tests that don't need xterm.
