You don't need to be root to run ns. And it is unsafe.
Please do all ns commands as unprivileged user.
'root' is for administrative tasks only.

% ns file.tcl : Will not work.

The command is simply : ns file.tcl

i tried sir but its not working.dont mine sir i'm very beginer to this sir i dont know the abc of it.I tried as you said
[root@localhost ~]# ns MAgent.tcl
couldn't read file "MAgent.tcl": no such file or directory
[root@localhost ~]# ns simple.tcl
couldn't read file "simple.tcl": no such file or directory

i also tried by going into the ns2.34

[root@localhost ~]# cd /home/karthik
[root@localhost karthik]# cd ns-allinone-2.34
[root@localhost ns-allinone-2.34]# cd ns-2.34
[root@localhost ns-2.34]# ns simple.tcl
couldn't read file "simple.tcl": no such file or directory
[root@localhost ns-2.34]# cd /home/karthik
[root@localhost karthik]# ns simple.tcl
couldn't read file "simple.tcl": no such file or directory
[root@localhost karthik]# ns simple.tcl
couldn't read file "simple.tcl": no such file or directory
[root@localhost karthik]#

Running ns2 files as root : You may have to delete all ns2,
and reinstall from scratch. And please do not use root (su).


Using a command, and pointing to a file :
The first command is 'pwd' , which will show your location.

So next you must either : cd <to-location-with-file.tcl>
Example : cd ns-allinone-2.34/ns2.34/tcl/ex/ && ns simple.tcl

Or use the full path :
ns ns-allinone-2.34/ns2.34/tcl/ex/simple.tcl

And if you have the MAgent.tcl on your Desktop :
cd Desktop && ns MAgent.tcl
..

@ goodGOD, post # 5 : Welcome to LQ.

Instead of all the troubles with 'setting a path', suggest :
cd ns-allinone-2.34/ns-2.34/
su
make install
..... which will copy 'ns' to /usr/local/bin/

The same can be done with nam : cd ns-allinone-2.34/nam-1.14/ , etc.

Then you will always have ns + nam in a system path :

Dear knudfl and all,


thanks for tips, all ns 2.34 is good and working now.

Please if I want to install NS 3 on the same PC and on Fedora 13.......is it possible ........will there be conflicts between ns 2.34 and ns 3 on the same machine.

I want to work on Optical Network, I was informed by a friend that NS 3 versions may be better but I first thought ns 2.34 should be more stable.


Also this PC IBM Lenovo G555 with Fedora 13 couldn't see the wireless card on the machine. I will like to configure it so as to connect to Wirelss Network. Please what are the steps I should follow to make it. thanks

Also what does this commect means ..........
it occurs after the ns 2.34 installation
I just put it in .bashrc file so as to work on it

Post # 8 : As the text says : If you ever happen to want to link against installed libraries ...
I.e. installed libraries = ns-allinone-2.34/lib/libtcl* , etc. : If you want to build software,
e.g. a new protocol in ns2, you may have to point to those.
( It has never occurred with anything, I tried to build.)


Post # 7 : ns3 is a totally different simulator software, not at all like ns2.
Nothing will conflict. NS3 is a python application. Please read this ( LQ ns3 thread ) :
