The "-y" flag to tcpdump allows you to specify capturing with DLT_LINUX_SLL2. //tmp @fenner-t493.sjc% tcpdump -i any -y linux_sll2 udp port 53 tcpdump: data link type linux_sll2 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on any, link-type LINUX_SLL2 (Linux cooked v2), snapshot length 262144 bytes 04:34:16.440349 ifindex 2 (e-a4c-281e9814) Out 8e:18:55:e1:02:4b (oui Unknown) ethertype IPv4 (0x0800), length 81: me.45555 > dnsserver.domain: 53929+ A? www.tcpdump.org.

I don't remember the details, but IMHO it was enabled by default. When now I compile libpcap and tcpdump, it's still using DLT_LINUX_SLL: tcpdump: listening on any, link-type LINUX_SLL (Linux cooked v1), ... What do I do wrong?
