Netfilter device

Netfilter device

[Nhan Thanh Le]

Dear All,

   I am new babie in netfilter linux, my project is caputre packet 
traffic through netfilter. I read the link at 
http://redvip.homelinux.net/varios/netfilter/netfilter-hacking-HOWTO-4.html. 
And I would like to do my  practice but I could not do it, because I 
could not find out where is the linux/include/linux/netfilter_dev.h or 
netfilter_device.h. Could someone help me to have it. Thank you very 
much and appreciate.

this has been replaced by the ip_queue mechanism (man 3 libipq).

If you're interested in just capturing (copies) of packets (not
re-injecting and/or modifying them), then you could look into using
the ipt_ULOG target (see the ulogd sourcecode for an example and a small
library).

Be aware that both ULOG and ip_qeuue are in the process of being
obsoleted by nfnetlink_queue / nfnetlink_log.  No docs for them yet.
