Subject: capture arp in hook and queue to userspace
Date: Wed, 25 Aug 2004 11:24:30 +0200 [thread overview]
Message-ID: <000201c48a85$59540ae0$0c02a8c0@Comcon2> (raw)
Hello,
I intend to capture all incoming packets (IP and ARP) and queue them for
userspace using the ip_queue module, and let my userspace application make
all verdicts. I have written a module using netfilter, and successfully
queued all IP-packets, but now I have no clue how to capture the ARP
packets, using this hook...
my_pre.hook = my_in_hook;
my_pre.hooknum = NF_IP_PRE_ROUTING;
my_pre.pf = PF_INET;
my_pre.priority = NF_IP_PRI_FIRST;
unsigned int my_in_hook( unsigned int hooknum,
struct sk_buff **skb,
const struct net_device *in,
const struct net_device *out,
int ( *okfn ) ( struct sk_buff *) )
How does the ARP hook work? What do I have to change to capture all ARP
packets? Please show me an example
Thanks for helping me,
Sincerely Magnus
