Good morning I downloaded ns-2.1b3 and ns was installed successfully without nam and xgraph. I compiled nam separately with success but still seem to be having problems with xgraph. I have also included the xgraph patches as suggested by the web page, with no success. However, when I run a script with ns, nam still gives me an execution error. I am using Solaris 2.6 gcc 2.8.1. WHAT AM I MISSING!!! -- tiki
