I need to build a Gnutella crawler, but I don't want to re-invent the wheel if there is a Gnutella crawler source code available already. I'll appreciate it if someone could give me a link to a crawler or something to start up with.

Thank you.

Gnutella crawler aren't open source because they can harm the network a lot. You can always ask the Gnutella developer forum http://groups.yahoo.com/group/the_gdf/ but I doubt they'll give you code. I warn you, crawling can be VERY damaging and should be done the LEAST times as possible.

Ciao

Thanks for replying. Yes I am ware of the harming effect a crawler can have on the network, but I think it is better to have an optimized crawler (open source), than to let amatuers develop their own crawlers. I'll ask in that group, thank you.
