Is there a way to do dns poisoning and make the poisoned server provide legitimate queries when doing dns lookup. Example: Assume I am running a poisoned dns server, when user X does lookup yahoo.com or dig yahoo.com I reply with legit yahoo entries, however, when user Y does the same thing I provide fake or spoofed entires.
I haven't checked the BIND source, but it *might* be possible to poison only one view in a split-view configuration. However, your control over who sees the poisoned entry would be limited to "any IP address who is served the given view". (Incidentally, you can't do "user X or user Y" for DNS, because the query packet doesn't carry any such authentication - the best you can do is "by IP address". This is a crucial but often overlooked distinction - users do *not* equate to IP addresses)
