There's some ICMP thingy to get the address mask from a router or sommat. If you read net/ipv4/icmp.c there are all sorts of comments about why it should/shoudn't be implemented, and when we should reply etc. etc. It ends up with: * All these rules are so bizarre, that I removed kernel addrmask * support at all. It is wrong, it is obsolete, nobody uses it in * any case. --ANK * * Furthermore you can do it with a usermode address agent program * anyway... */
static void icmp_address(struct icmphdr *icmph, struct sk_buff *skb, int len) { if (net_ratelimit()) printk(KERN_DEBUG "a guy asks for address mask. Who is it?\n"); }
If anyone has a more complete explanation of what these packets actually are, I would be interested.
HTH.
