You are right, it is invoking ns in '/usr/bin/ns' every time I type
ns. I tried the absolute path as you suggested and it works! Well not
really.
I get the following error now
$ ns: finish: couldn't execute "nam": no such file or directory
while executing
"exec nam ptrace.nam &"
(procedure "finish" line 6)
invoked from within
"finish"
What is happening here?
So now I have two problems. First, how do I avoid typing the absolute
path every time I want to run ns-2? Could I rename the name of the
ns-2 executable file - would that simply do?
And also, what is this second error?
Thanks for your help - sorry for the delay in this reponse!
