Description of Problem: Selected Network Management Tool in nautilus. It shows no network devices configured on the system. Repeated from a terminal with /usr/bin/neat-control and got same result. /usr/bin/neat works, though, and shows eth0 quite happily. redhat-config-network-0.9.18-1
Is still still an issue for you? It works for me (and give 0.9.20-1 a try - you can find it at http://people.redhat.com/teg/neat/)
It's not a bug. neat-control does not run with SUID as neat does. If you run neat-control as normal user and your network config files are only readable for root, neat-control cannot access them. It's a reason why neat-control cannot list your network.
