Static ARP Entry

[STeRoiD]

Hey guys, has anyone ever seen something like this :

I got Win98 box, and I want to make a static arp cache entry for some IP, so I deleted all the arp entries using arp -d option, verified it using arp -a (No ARP Entries Found), and then tried to add it using arp -a <IP> <MAC> option.

But no matter what MAC Address I put for that IP, when I view the entries using arp -a, I always see the same MAC Address for that IP (NOT the one i was inserting!), with static Type.

Any suggestions what is going on?

it seems i knew about The ARP .. but never try on win98.
and i found good site and perhaps it could help you.

After loading the ARP files, you will need to perform a workstation

to read the overview you may click here .

i hope it can help you.

good luck mate.

I can't really understand why do you want to use a different MAC-address than the one which is wrote to network adapters ROM. It seems that 'arp'-command reads the 'real' MAC-address from adapter and discards the one you've given.

As said, MAC-addresses are programmed into each physical hardware device, so IF you really need to change it, spoofing is a partial solution. However I don't know is it possible with 98 (newer MS OS's it is.).

First of all: thanks, its nice, but its not exactly what i asked for.
It changes YOUR MAC address, and not an entry for some other computer...

Cant i bypass that somehow?

Im just researching my own home network. chapter is arp spoofing

then tried to add it using arp -a <IP> <MAC> option

It won't work because option -a only show current arp-settings and option -s ADDS one.

I also found a document about 98's arp-bug, read it here: http://www.securityfocus.com/[email protected]
