Hi, I'm really a NS beginner. I installed NS-allinone-2.29 by Cygwin on WindowsXP and then I downloaded example1.tcl from Marc Grei's tutorial pages but I have problem processing it. This is the error when I launch "ns example1a.tcl":
ns: finish: couldn't execute "nam": permission denied while executing "exec nam out.nam &" (procedure "finish" line 7) invoked from within "finish" Can you help me? Sorry for my poor english. Andrea.
