Libpcap

["Chris Davies" <cjd () slowglass com>]

Trying to get libpacp to work in 32 bit mode on 64 bit machines.

 

I have a program that uses libpcap to snoop on packets for the purposes of
monitoring.

It works very well when compiled on a 32 bit Linux machine and run on a 32
bit Linux and when 64 bit Linux machine and run on a 64 bit Linux.

However it does not work correctly if I run the 32bit binary on a 64 bit
Linux box. Is there something special I should be doing.

 

A simplified segment of my start code is

    pcap_t* handle = pcap_open_live(dev, BUFSIZ, 1, 1000, errbuf);

    pcap_set_buffer_size(handle,bufSize);

   pcap_compile(handle, &fp, "src port 80",1, net);

   pcap_setfilter(handle, &fp);

   pcap_loop(handle, -1, got_packet, (u_char*)handle);

 

Is there anything special I should be doing to get it to work on 64 bit
platforms
