Can you give me an example of <netname>.<br>
<br>
My eth0 device is assigned a public ip address, but I will not use
tinc to secure traffic over that interface.<br>
<br>
There will be an eth1 device that has a externally visible IP
Address. It is on this eth1 device that I want<br>
the virtual tun0 device to route its traffic.<br>
<br>
Maybe under Ubuntu, I will have a different device name tun0? (I
only tested tinc on centos6 earlier)<br>
<br>
Thanks,<br>

You can just use the normal /etc/network/interfaces way of configuring
the interface, like this:
iface vpn inet manual
address 192.168.1.1
netmask 255.255.255.0
tinc-net <netname>
</pre>

During boot, all services that require the network is online are started
AFTER all auto interfaces in /etc/network/interfaces have been brought
up.

There's /sys/class/net/<interface>/operstate, which should exist and
contain "up" when the interface is up. Otherwise, there's the netlink
interface, but I've never worked with that myself.
But be warned, whether an interface is up still doesn't mean that your
network is actually working. For example, you'd want to mount a NFS
share if the interface is up AND if the NFS server itself is up and
reachable. If you can instead make your services more resilient to
changes in the network state, that would be better.
