I also would like to help you, therefore some questions in advance to
come to a good solution:
– Which simulator version did you download and do you use?
– Gnutella 0.4, Gnutella 0.6 and GIA are unstructured overlays in the
simulator. Did you try to simulate those using the corresponding
config files in the config-directory?
– Did the getting started document help you:
At which point did you had some troubles?
