Shutting all nodes down (rtnet stop), changing rtnet.conf files, and restarting them? Could you try to capture the traffic with Ethereal/Wireshark so that I can have look if there are correct TDMA packets exchanged? > 2.

(My other > e1000 port is then up). That's very likely some hotplug automatism of your distribution. Watch out for related services/daemons (I don't know Fedora, sorry) and stop them for now. Jan
