In a report, and to avoid false positive, should be usefull to identify which IPs are on the same server, but how? If I should be in the internal network I am testing I'll use arp to find the MAC address of each IP and I should have solved, but from Internet I cannot use arp.From Internet I could use the banner, but this is not sure, I could have more then one application server on the same server with n-IP on application server A and m-IP on the application server B getting the banner should not be the right choise especialy with proxy.Any idea?You could use the TCP Timestamp option to see the uptime of both servers. If it is similar enough, there is a good chance it is the same server. (unless the loadbalancer changes the Timestamp...) See section 3.2 here: http://www.faqs.org/rfcs/rfc1323.html Regards, Yonatan Bokovza IT Security Consultant Xpert Systems
Yep, TCP timestamps, TCP sequence numbers and IP ID's. Plus, of course, OS fingerprinting and banner grabbing. ISNprober, hping2, nmap and both xprobes will do the job.
Cheers, Andrew
