Hi Martijn, your mail made it to the list, no problem here ... but no answers yet. Unfortunately I don't know the answer to your questions. Instead, I am very interested and I am waiting for answers and recommendations as you do since I would like to know that. Any help? Regards, Michael Doerner
My previous post didn't seem to make it to the list (anyone else who has that problem often), so here goes again.
I've been playing with ethereal a little, and I noticed that some webservers do an ARP lookup on my machine's IP address. This box is located behind a firewall, it is MASQ-ed and has a private IP.
How is it possible that a webserver can request the hardware address of my MASQ-ed machine? Is something wrong with the MASQing setup or am I overlooking something.
Is it necessary from a local network point of view to have ARP enabled (I could disable it with ifconfig)? If so, is it possible to deny (at the firewall) ARP-lookup requests from untrusted servers?
I feel that giving away this kind of data is like giving away a Pentium III's serial number. Am I wrong or am I just being paranoid.
Bye,
Martijn
