I realize now that I have confused IGMP with EGP & friends. Looking at /etc/protocols could have saved me from this. :) igmp 2 IGMP # internet group management protocol egp 8 EGP # exterior gateway protocol > So that's why you're seeing IGMP queries; the multicast router > is trying to see if you've joined any multicast groups so it > can try to send you traffic.

The bad feelings I have with these is when reading Linux mailing lists (far behind in the past:) where people always wondered "why does my ISP connection always go up / keep up?" when they thought running routed(8) would be a Bright Idea (TM). Thinking about routing in a LAN with four machines and doing it manually must be very demanding. :> And again see my above confusion with EGP. OK, there's sooo much yet to learn for me ... Keep buzzing when I do something wrong, I'm very *happy* with getting corrected. :) virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
