[tcpdump-workers] Inject payload with crypto algorithms
Hi, I am implementing one application using libpcap but I am unble to use pcap_inject is failing it showing undefined reference to this function...I searched header file also The function is not avalible.. My requirement: case1: I have to recevie the packets from 3000 port of one internal device (interface).I have to apply encryption and send back (inject payload)to same port again of interface case 2:I have to get the 3001 port for decryption again I want send back to same using libcap functions doubt: If receive the packet payload its in (decrypted format)in original data but I want to apply double encryption for packets encrypted data..how should I get the encrypted data.. I would like ask you send any sample code using any crypto algorithms and libcap. It might be help ful for my application..

It *isn't* available in libpcap prior to 0.9.0; what version of libpcap do you have on your machine? If it's not 0.9.x or 1.x, you don't have pcap_inject().- This is the tcpdump-workers list.

You should specify what version of libpcap you are using and the OS. On last ubuntu with libpcap 1.1.1 pcpa_inject is defined on pcap/pcap.h and I can successfully link that function with my code.
