hey chad, thanks for your reply
your example above would give me
$listenip = "192.168.0.1_eth0"
but instead i need
$listenip = "%IP_OF_SOME_NETWORK_DEVICE%"
, where the "device" is dynamic means, it could also be eth1, or even
tun0 etc.
since i do not want to set fixed ip's in every single node definition
lets explain some more,
lets say you do have some servers on the cloud
where eth0 is the "bad and evil" network interface,
you do not want to have any of your services on this one
even thought there could be a firewall etc. but that is not the point
in here.
and tun0 ist your "good and shiny" interface, where all your company
traffic gets over a secured vpn link
how would you tell every node that it's services should just run on
lets say tun0, without "hardconding" to a module or class
eh. while writing the things above, i'd propably found a solution:
node definitions says: $listenif = eth0
now the "magic" class comes to it's action and has the following code:
case $listenif {
eth0: $listenip = $ipaddress_eth0
eth1: $listenip = $ipaddress_eth1
tun0: $listenip = $ipaddress_tun0
tun1: $listenip = $ipaddress_tun1
}
eh, makes me feel a bit stupid that i haven't got the idea earlier,
anyway the best solutions come into our mind when we step back and
take a look from further away ain't they
hopefully it's working tomorrow when i try it out
