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,
}

luodeke:博主你好,我有个问题想请教你,看你的博文里面你好像有看过内核代码,内核代码你是从哪里得到的呢?直接在kernel.org里面的源码包得到的吗?多谢
两种方法
1、去 kernel.org 下载
2、用 git 直接托追最新版:git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
