Segmentation fault :
A simulation with too many nodes, or other impossible simulation ?
? Wrong OS ? Wrong architecture ( x86_64, i686 ) ?

Some information is required to answer your question ..
http://www.linuxquestions.org/linux/...Ask_a_Question
http://linuxsilo.net/docs/smart-questions_en.html
a) OS name and version
b) Architecture, x86_64 or i686 : $ uname -m <Enter>
c) The version of your ns-allinone-2.xx .
d) The changes / patches that were added to ns-<??>
e) The file.tcl with issues must be attaced as <name>.tcl.txt .
Attachments : That's the paper clip tool in the 'Advanced Editor'.

Operating system windows 8. Vmware is installed and we are using fedora.
It shows as follows-
OS-other linux 2.6x kernel
Workstation-6.5-7.x virtual machine.
We are operating ns2.32 on it.

We have implemented our base paper and in it we have used 2 different topologies-
1-random topology (by which we got successful output with 100 nodes)
2-equilateral triangular topology(in which we got the error “Segmentation fault (core dumped)” with 100 nodes in terminal.)
The error doesn’t occur immediately after executing the proj.tcl(attached) but, it first starts executing properly and after few seconds it shows the error.
Also just to verify, we implemented the same triangular topology with LEACH protograph.txtcol and it was successfully implemented

# 3 .

You forgot to answer two questions : OS version ==> $ cat /etc/redhat-release
* And : $ uname -m <Enter>


Ns2 has it´s limitations ... see post #2 here :
