Static Network Configuration
The default configuration provides multiple services that perform network
initialization and static configuration using helper scripts that require
programs from the
Configuration files are typically stored in
/etc/netcfg/ (depending on
Please note that the loopback device is treated specially and not included in any of the network configuration outlined below. The loopback device is brought up and configured by a dedicated service long before the network configuration is done.
ifrename service is enabled (it is disabled by default), network
interfaces are renamed based on a rule set stored in the file
The file contains comma separated shell globing patterns for the current
interface name, MAC address and a prefix for the new interface name.
For each network interface, rules are processed top to bottom. If the first two globing patterns apply, the interface is renamed. Interfaces with the same prefix are sorted by mac address and a running index is appended to the prefix.
If none of the rules apply, the interface name is left unchanged.
The intent is, to provide a way to configure persistent, deterministic names for at least all network interfaces that are permanently installed on a board.
Extension cards or external network adapters should be given a different prefix to avoid changes in the order as they come and go.
Static Interface and Route Configuration
After interface renaming, an iproute2 batch script
executed with the
-force option is set, i.e. it will plough throug the
entire script without aborting, but the service will be marked as having
failed if any of the batch lines fail.
Net Filter Tables
An additional service is provided that restores the nft rule set from
DHCP based network configuration
If the configure option
--enable-dhcpclient is set, two services are added.
dhpcdmaster launches a global dhcpcd instance.
For each port that should be configured via DHCP, the service
to be enabled manually with the port name as argument. The service the runs
after the master service and sends a signal to the master to operate on that
