try this command...
first as first remark
its preferable to work under this directory : /ns-allinone-2.33/bin and put
in it the trace file , the nam file and obviously the Tcl file..ok
second
i will suppose that you have done this.so to run the nam file :
exec ./nam /home/faraz/Desktop/ns-allinone-2.33/bin/attachment &
i hope that it will work
