OK, I some how got it working with Fed 8,
But Fresh install of Fed 9,
Installed rwho. each box has a eth0 (internet) and eth1 (lan via crossover cable)
Both boxes can ping one another 192.168.0.1 (master) 192.168.0.2 (slave)
Both boxes are using eth1 for the crossover connection. and can comunicate np with one another via web services... Apache & MySQL
Problem is I can't get rwhod, rwho, ruptime, rusers to read the status of each other via eth1
iptables & iptables6 are both disabled
network started b4 rwhod
rwhod started after network
hosts file has each box ip/named set
not much docs for "help" in the rwho service and configuration
