I have a problem with the dns-spoof plugin for ettercap. It works for some clients and some websites, but its really random. What i do is use the GUI version, then first Unified sniffing, then scan for hosts, then add the router as target one, and the other IP's as target 2, then i start arp poisoning, then start sniffing. Then I run dns-spoof under plugins, and this is where the problems start. I can spoof my own computer, but neither of my other laptops get spoofed all the time. I have www.* set as the spoof URL, but only some sites work. I even cleared the DNS cache, and no luck.
Any insight to my problem is greatly appreciated.
