Hi, I've received a bug report that tcpdump crashes when -i option is used and there are no interfaces available. https://bugzilla.redhat.com/show_bug.cgi?id=497819 This should fix it: --- a/tcpdump.c +++ b/tcpdump.c @@ -655,6 +655,8 @@ main(int argc, char **argv) if (pcap_findalldevs(&devpointer, ebuf) < 0) error("%s", ebuf); else { + if (devpointer == NULL) + error("Invalid adapter index"); for (i = 0; i < devnum-1; i++){ devpointer = devpointer->next; if (devpointer == NULL) Thanks, -- Miroslav Lichvar - This is the tcpdump-workers list.
