Thanks for the quick answer, the question about this can be found here: http://www.tcpdump.org/lists/workers/2003/08/msg00244.html unfortunatly there wass now reply (or maybe I can't find it). So I think I'll go the safe way and restart capturing. Another interesting aspect would be, what happens when I change the filter in the callback-function (which runs in the same thread). Will the old one be replaced for the next packets? regards Stephan Knabe - This is the TCPDUMP workers list.
