I was trying to send packets on to the LAN,but unfortunately was finding some probs. I wanted to know how we add delay in order to send the packet. Is there any other alternate way to send packets on the LAN port rather than Libpcap. Suggestion most appreciated. Cheers. libpcap allows us to capture or send packets from a live network device or a file. This tutorial and code examples will walk you through using libpcap to find network devices, get information about devices, process packets in real time or offline, send packets, and even listen to wireless traffic. I have some data packets captured using tcpdump in a pcap file. Now I want to send those packets to a another destination. how I can achieve this?

On Linux-based systems an alternative way to send an Ethernet frame is to use an AF_PACKET socket. This has some advantages over the use of libpcap: It allows packets to be written directly to a POSIX socket descriptor, making it possible to use facilities such as scatter/gather and non-blocking output, and providing compatibility with libraries like libevent that act on file descriptors.
