I am going to import libpcap 0.8.3 and tcpdump 3.8.3, and then apply my patches for radiotap (802.11 radio capture header) support to tcpdump. Any problems with that? (Right now we have libpcap 0.4 and tcpdump 3.7.1.) Dave -- David Young OJC Technologies dyoung@ojctech.com Urbana, IL * (217) 278-3933
