Stephane Bortzmeyer With help from: W. Richard Stevens, author of the book "Unix network programming" for his book and his many examples (a lot of the code comes from him by copy-and-paste). Pierre Beyssac author of the "bing" tool for examples of code and beta-testing. Christian Grimm for the ICP code. Samuel Tardieu for the SMTP code. Pierre-Yves Lochou for a lot of testing, debugging and porting. Bertrand Petit for a lot of testing, debugging and useful comments and advices. Glen Turner for the Type Of Service code. Munechika Sumikawa , from KAME, for the adaptation to the new API, which allows IPv6. Luca Deri for the patch separating kernel (TCP) and application latency. Andy Juniper for the patch which excludes outliers from averages and from bug fixes on statistical calculations. SourceForge for the very good environment to work with. SourceForge changed the life of many free software programmers!
