FreeBSD 5.4 "Stock" pcaplib I'm blocking on a read() invoked by pcap_lookupnet():
Program received signal SIGINT, Interrupt. 0x280ee6fb in read () from /lib/libc.so.5 (gdb) where #0 0x280ee6fb in read () from /lib/libc.so.5 #1 0x28090c57 in pcap_lookupnet () from /usr/lib/libpcap.so.3 #2 0x28091adb in pcap_loop () from /usr/lib/libpcap.so.3 #3 0x08049cb9 in myTest (c=0x8054b20, pcb=0x804ac5c <myTestCallback>) at myfile.c:532 #4 0x08049b58 in runTest (c=0x8054b20) at myfile.c:454 #5 0x08049406 in main (ac=13, av=0xbfbfec1c) at myfile.c:149 (gdb) I don't get this behavior on Linux, but the interface on FreeBSD is configured via DHCP while the Linux interfaces are staticly configured. Any idea as to whether that's a red herring, or a difference that could cause the pcap_lookupnet() to hang? Happy to RTFM / STFW if pointed in the right direction. - This is the tcpdump-workers list.
