Hi
I am now in trouble with ns and nam. I downloaded and run the sample from
ns-tutorial page without no modification and had these problems:
- When I execute the example file with the command: "./ns example.tcl", it
cannot open nam for simulation. The following message appeared:
ns: finish: couldn't execute "nam": permission denied while executing
"exec nam out.nam $"
<prodedure "finish" line 9>
invoked from within
"finish"
I did not really understand the authority in executing nam, and what is the
"invoked from within".
- When I execute the example file with: "./nam nam-example.tcl", the
following message appeared:
"nam: no display nam and no $DISPLAY environment variable"
Thank you very much,
Anh
