Iperf 2.0.2 is available from the dast.nlanr.net web page. This release fixes the multicast TTL bug, addresses the buffer overflow mentioned by Hans Blom and others (as well as rationalizing 64/32-bit matters via suitable m4 macros), and cleans various configuration issues. Feedback is very much appreciated; I hope to address other outstanding bugs on the way to a 2.1 release this summer. -- John S. Estabrook jestabro --at-- ncsa.uiuc.edu jestabro --at-- dast.nlanr.net
