Hi Guy, In config.h file: /* define if you have the DAG API */ #define HAVE_DAG_API 1 so I think it is set. The output of ldd on tcpdump is: $ ldd tcpdump tcpdump: libcrypto.so.3 => /lib/libcrypto.so.3 (0x2810d000) libc.so.5 => /lib/libc.so.5 (0x28204000) I don't know if or not libpcap should show up here. But I did notice the output of ./configure when I compiled tcpdump before, it outputs "checking for local pcap library... ./../libpcap-0.9.8/libpcap.a". That's exactly the dag-enabled libpcap I installed. Lei On 1/9/08, Guy Harris <guy () alum mit edu> wrote:

When I typed "tcpdump -i dag0", it gives me the error "tcpdump: BIOCSETIF: dag0: Device not configured". Could anyone give me any hint on what the problem is?The problem is that the libpcap being used by tcpdump isn't DAG- enabled for some reason; it's trying to attach to adapter "dag0" using BPF, not using the DAG code. Is HAVE_DAG_API set in config.h in the source directory for the libpcap you built? If so, what does "ldd" print when you run it on the tcpdump you built? - This is the tcpdump-workers list.
