I have two network cards and was working on eth1. Something happened when I was figuring out how to change the settings via command prompt to make an error occur on eth0. The error says "error some other host already uses this ip address." Nothing is using the ip address and I can't ping it or locate it in any way.
I am also seeing a "netfilter" message pop up. when I restart things. I don't remember that in the past.
Thank you in advance for your help.
