I found the cure in the bottom of /etc/dhcpcd.conf, define a static_eth0 and a fallback to it if a dhcpd server can't be found, did it, rebooted and its fixed. I have a network. Why isn't that in the wiki? Neither is there any reference to avahi that can be found in the wiki and I spent around 2 hours search and browsing it.. Frustrating is an inadequate description. Adequate isn't for mixed audiences.
Anyway, its fixed. How long? Beats me... Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
