Packet size question
From: Justin Hopper <gus () gusalmighty com>

Hello list members, It's funny that a search for libpcap or pcap on google doesn't return much of any useful links. For most programming projects, usually a couple searches for libraries or syntax returns a ton. So, I'm a bit short on docs for working with libpcap. I'm new to pcap, so please forgive any of the ignorance in my questions, and any help or guidance is greatly appreciated. Question 1) What variable should be used to see what the actual size of the currently read packet is? struct pcap_pkthdr->len? struct ip->ip_len? something else? Qustion 2) Will fragmented packets affect any of the above structures when trying to effectively count data moving across the wire with libpcap? Thanks again for any help. -- Justin Hopper <gus () gusalmighty com> - This is the TCPDUMP workers list.
