How to use a DAG card with ntop ------------------------------- Why DAG? ======== DAG is a very fast and efficient card used for capturing traffic at very high speeds. If you have a fast (Gbit and above) network then this is probably the very best solution you can find on the market. How to use ntop on DAG ====================== 1. Get a DAG card from Endace (www.endace.com) 2. Get the DAG toolkit from Endace and install it (e.g. on /usr/local/dag) 3. Get lipcap 0.81 or newer from www.tcpdump.org 4. cd libcap-XXXX ./configure --with-dag=/usr/local/dag make make install [as root] 5. Get the ntop source (see http://www.ntop.org/download.html) from CVS 6. Compile ntop as usual but do make sure that ntop uses the libpcap you've just compiled. Credits ======= Many thanks to Endace for having donated a DAG card to the ntop project for the purpose of integrating it with ntop. ------------------------- Luca Deri - December 2003
