Re: ARP table questions
i got the same problem with vista ultimate running in a switched network
where a W2k3 Server acts as DHCP and DNS Server so i get my IP automatically.
We were trying to capture the data in the network with my Vista Laptop which
worked fine via ARP-Spoofing. The other machines in our network are mostly
WinXP Pro/Home pc's and we have one Mac OS X Client.
It was no problem to add a batch file containing
arp -s IP MAC
to the autostart dir so that the ARP Tables are modified with a static ARP
entry for the Gateway everytime you boot up your system.
I tried everything to modifiy my own ARP entries. I set the "Run as
Administrator" flag for cmd and the batch file. I tried to type arp -s IP
MAC, i tried to launch the batch file, i retried everything shortly after a
reboot, i deactivated the LAN-Interface but nothing worked for me.
I tried this Man-In-the-middle attack to show all 11 clients in the network
how unsecure it is and now everyone tries to spoof each other. I don't know
how to get the Macintosh Secure but every single d**n XP machine now protects
itself with a static ARP entry for the Gateway. Vista is unable to do the
Is there ANY solution for this problem out there?
