Do they both report packets being captured, or does just the one capturing on wlan0 report packets?Yes, I just checked."Yes" they both report packets being captured (in which case there's probably either a problem with your program or with libpcap), or "yes" only the one caputring on wlan0 reports packets (in which case it's probably a problem with the way either the Linux wireless framework or your wireless driver works)?I meant: yes they both capture packets at the same time. But, I already tried something similar since I tried a few times to do the same with processes and they were working (both processes (on eth0 and wlan0) were capturing packets). Thnaks for the answers. Johan
