############################################################################## # QUICK-START # # The quickest start is if you want to use DHCP. # In that case, everything should work out of the box, no configuration # necessary, though the startup script will warn you that you haven't # specified anything. # WARNING :- some examples have a mixture of IPv4 (ie 192.168.0.1) and IPv6 # (ie 4321:0:1:2:3:4:567:89ab) internet addresses. They only work if you have # the relevant kernel option enabled. So if you don't have an IPv6 enabled # kernel then remove the IPv6 address from your config. # If you want to use a static address or use DHCP explicitly, jump # down to the section labelled INTERFACE HANDLERS. # # If you want to do anything more fancy, you should take the time to # read through the rest of this file. ############################################################################## # MODULES # # We now support modular networking scripts which means we can easily # add support for new interface types and modules while keeping # compatability with existing ones. # # Modules load by default if the package they need is installed. If # you specify a module here that doesn't have it's package installed # then you get an error stating which package you need to install. # Ideally, you only use the modules setting when you have two or more # packages installed that supply the same service. # # In other words, you probably should DO NOTHING HERE... ############################################################################## # INTERFACE HANDLERS # For a static configuration, use something like this #config_eth0="192.168.0.2/24" # If you need more than one address, you can use something like this # NOTE: ifconfig creates an aliased device for each extra IPv4 address # (eth0:1, eth0:2, etc) # iproute2 does not do this as there is no need to #config_eth0="192.168.0.2/24 192.168.0.3/24 192.168.0.4/24" # Or you can use sequence expressions #config_eth0="192.168.0.{2..4}/24" FIXME - may not work with baselayout2 # which does the same as above. Be careful though as if you use this and # fallbacks, you have to ensure that both end up with the same number of # values otherwise your fallback won't work correctly. # You can also use IPv6 addresses # (you should always specify a prefix length with IPv6 here) #config_eth0="192.168.0.2/24 4321:0:1:2:3:4:567:89ab/64 4321:0:1:2:3:4:567:89ac/64" # If you wish to keep existing addresses + routing and the interface is up, # you can specify a noop (no operation).

To get around this you may alter the carrier_timeout value for # the interface. -1 is disable, 0 is infinite and any other number of seconds # is how long we wait for carrier.
