The other day we started using Cisco netflow accounting software together with IP flow export feature of recent Cisco IOS versions. What we found was that although we put a lot of protocols in the nfknown.protocols file of the accounting software (everywthing we could find in the /etc/services file of Solaris and Linux), there is still a lot of traffic under TCP-Other and UDP-Other. This indicated that traffic is going over our network using ports that the software doesn't know about. This could for example be Real-audio, Cuseeme, Pointcast, Backweb etc traffic. Unfortunately, I don't have a list of these newer protocols together with their port numbers. Has anyone compiled such a list? There's the Assigned numbers RFC but the last version of it is RFC 1700 of October 1994. -- Steven
