Grokster is not connecting to Gnutella
go in go in core/com/limegroup/gnutella/ and open ConnectionManager.java
search for "if(userAgent" You'll have to copy two times the list of hosts banned because you have to block them from connecting as UPs to you (private static boolean allowUltrapeer2UltrapeerConnection) or as a leaf (private static boolean allowUltrapeer2LeafConnection).
After the lines:
if(userAgent == null)
return false
paste:
if(userAgent.startsWith("morph")) return false;
if(userAgent.startsWith("Kiwi")) return false;
if(userAgent.startsWith("Trusty")) return false;
if(userAgent.startsWith("MLDonkey")) return false;
if(userAgent.startsWith("Xolox")) return false;
if(userAgent.startsWith("Kiwi")) return false;
if(userAgent.startsWith("giFT")) return false;
if(userAgent.startsWith("360Share")) return false;
if(userAgent.startsWith("eTomi")) return false;
if(userAgent.startsWith("Etomi")) return false;
if(userAgent.startsWith("Shareaza")) return false;
if(userAgent.startsWith("iMesh")) return false;
Compile core and voilà!
Ciao
