Also, I think the change should probably go into at least the osscan.cc:174 instance below (changing to a decrement should be fine):I just searched through the other RFCs, and it looks like only UDP has this rule. So, yeah, only the osscan.cc should be changed.
Search through the various kernel sources instead, and you'll find that the same holds for IP, ICMP and pretty much every packet-type availabled. UDP might be the only protocol it's RFC'd for, but it's done for all of them (on most systems). -- Andreas Ericsson andreas.ericsson () op5 se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
