ARP Spoofing Prevention [solved]

Hi

I've been target of some ARP Spoofing in my network lately (by some scriptkiddies using cain)
I now want to prevent further attacks by setting a static ARP table.
I set my network to a static IP and wanted to map my MAC adress to this IP (this method is suggested in wikipedia)

I did

 
arp -s STATICIP MACADRESS pub

without the pub flag I get "Invalid argument".
Now I get:

 $ arp -a
? (192.168.178.19) at * PERM PUP on eth0
? (192.168.178.19) at * PERM PUP on eth0

I now installed Cain on my windows machine to see if it works, but nothing changed. I still can log passwords and stuff..

Did I configure anything wrong or is this method insufficient for preventing arp spoofing?

Re: ARP Spoofing Prevention [solved]

mapping the routers IP to its MAC works, don't use your machines IP
