$ ns preethisingh.tcl
... I get : "invalid command name "Agent/Security_packet".

* You will have to tell which "extra protocol" you have added.

The edited file "preethisingh.tcl" is attached.
Your "my_tcl_file.tcl.txt" is missing the last two lines.

I have added a new packet type to NS2. named. security_packet. Does the error mean that there is no path between source node and destination node? if so where have I made the mistake in my tcl file..pls help.

A new packet type would appear in :
ns-<unknown-version>/<folder>/file.cc
common/packet.h
tcl/lib/{ ns-decault.tcl?, ns-lib.tcl?, ns-packet.tcl, etc.}

+ that all changes to files in ns-2.xx///{ files.cc, .h, tcl/lib/**}
.. must be compiled into a new executable 'ns' : $ make clean && make

.. Then the new function may be usable in a simulation.

when I added new packet type to ns 2.35 . I made the following entries
1)I added security_packet.cc and security_packet.h to ns-allinone-2.35/ns-2.35/apps
2)then I made entry in packet.h
3)then in ns-default.tcl
4) then in ns-packet.tcl
5) then makefile.in
6)then I used ./configure
7) then make
should I make any change in tcl/lib/ns-lib.tcl ?? or anywhere else

If 4) 5) 6) are the commands you used, you missed 'make clean'

Please do : $ make clean && make

Now I used make clean and then make.. still im getting the error mentioned in #1. do I have to make any change in tcl/lib/ns-lib.tcl while adding new packet type?

I don't know.

? May be you are just using "new packet type" in an impossible way ?
