Hello,

I have been trying to parse PCAP files generated by the latest version of
ULOGD2 with PacketQ (https://github.com/dotse/packetq), without success.

sbin/ulogd -V 
ulogd Version 2.0.4
(C) 2000-2006 Harald Welte <laforge at netfilter.org>

PacketQ needs link-layer information to be present in the PCAP file to be able
to parse it correctly.

After a quick search, I found the following discussion on your mailing list :

http://marc.info/?l=netfilter&m=140625326302696&w=2

Since I did not find an opened ticket regarding this, I figured I'd create one.

"Another solution would be to add an options forcing the layer2 type for all
logged packets of given pcap output. This would allow to use kernel provided
layer2 information and write fully qualified packets for encapsulation like
Ethernet."

This solution would be enough for my needs !

Thanks.
