Is it possible to track and log dns queries by IP or HW address with IOS?
This is a smaller network, 30 or so users. They have no network management or security aside from a 867VAE branch router, only on offsite syslog server.
I know there are tools made for this but I have been tossing around how to rig it in IOS to basically provide me a log of who is requesting what.
I thought of perhaps dns views, but I need to log the domain and time of the request. This was just thrown in my lap after a weekend long marathon or other work, so maybe I'm just not thinking straight.
How can I get something like this to work with out adding hardware?
