nam not working ns2.33
I installed ns2.33 on fedora 16 but nam is not working.
i downloaded and unpacked nam 1.14. I copied it to usr/local/bin.
when i run a tcl script it gives following error :
[root@localhost programs]# ns 5nodes.tcl
ns: finish: couldn't execute "nam": permission denied
"exec nam out.nam &"
(procedure "finish" line 6)
invoked from within
thanks in anticipation
