Re^2: arp request forging

Ok, I'm not sure of this. But I thinked that if I want send an arp request to an host, I must specify mac address destination and peraphs its ip address.

I know that in C language is possible forging arp packets. In Net::RawIP I read:

The ARGOFDEST and the ARGOFSOURCE can be given as a string which contain just 6 bytes of the real ethernet address or like the output of the ifconfig(8) e.g. 00:00:E8:43:0B:2A or just an ip address or a hostname of a target, then a mac address will be discovered automatically.

Can you help me? tnx very much

Ok, I'm not sure of this Well, if you're not sure of this, then are you really in a postition to be sending out faked ARP packets onto the wire? I can't think of any reason why someone would normally want to do this, so unless you can convince me that (a) you aren't up to no good, (b) there is a valid reason for doing this, then I'm not keen to help you further. Sorry, Dave.	[reply]

My purposes could be.. arp poisoning, create an arp proxy.. and I would like to write a script for a gatway to permit to a host with different ip address (different classes) to connect.. etc. etc.. a strange project of my friend. Can you help me?	[reply]

Hmmm... well since ARP isn't an IP type but sits directly on top of the ethernet layer, you need to create a raw ethernet packet. I've never used Net::RawIP, but a quick look at the documentation seems to imply the ethset, ethsend, and/or send_eth_frame methods may be what you need. You'll need to construct the raw ARP packet yourself. Dave.	[reply]
