I used the same IP, Port, nodes.dat for eMule and aMule's configuration, eMule can connect to the KAD, but aMule just send the request and I haven't seen any response using wireshark, I also stopped the iptables on my ubuntu, so it shouldn't be the firewall problem because my windows machine and linux machine for test is on the same location! My aMule's version is CVS20080508. Could anyone give me a help? Thanks!
