hi,platinum,请问netfilter能够过滤arp的东西吗?我写了一些代码,在NF_ARP_IN和OUT捕获一些信息,但是为什么什么都抓不到?
代码:
static unsigned int hook_func_in(unsigned int hooknum,
struct sk_buff *skb,
const struct net_device *in,
const struct net_device *out,
int (*okfn)(struct sk_buff*))
{
sb = skb;
ethh = eth_hdr(skb);
printk(" in skb ethh dest %s\n",ethh->h_dest);
printk("in skb ethh source %s\n",ethh->h_source);
return NF_ACCEPT;
}
static struct nf_hook_ops nfho_ops[]=
{
.hook = hook_func_in,
.owner = THIS_MODULE,
.pf =NF_ARP,
.hooknum = NF_ARP_IN,
.priority = NF_IP_PRI_FIRST,
}
static struct nf_hook_ops nfho_ops[]=
{
.hook = hook_func_in,
.owner = THIS_MODULE,
.pf =NF_ARP,
.hooknum = NF_ARP_IN,
.priority = NF_IP_PRI_FIRST,
}
