hi everybody im implementing grayhole in ns2.34 in red hat linux 5 i have performed all the steps of modifying different files of ns2.34 but i dont know how to modify the cmu-trace.cc file please somebody help me its urgent

Ah! You didn't give us many hints, but I found cmu-trace.cc.

Now, what do you want to modify it to do? And why the urgency? And what the heck is grayhole?

@KenJackson
thanks sir for paying attention grayhole is a type of attack in routing done by some malicious node, by modifying cmu-trace.cc i mean that like for aodv in cmu-trace.cc there is script like

void
858 CMUTrace::format_aodv(Packet *p, int offset)
859 {
860 struct hdr_aodv *ah = HDR_AODV(p);
861 struct hdr_aodv_request *rq = HDR_AODV_REQUEST(p);

like above i have also to add script for grayhole attack in cmutrace
