These can be nested as well. + +This sets up a simple static configuration for eth0. "proto" specifies the +'protocol' used for the interface. The default image usually provides 'none' +'static', 'dhcp' and 'pppoe'. Others can be added by installing additional +packages. + +When using the 'static' method like in the example, the options "ipaddr" and +"netmask" are mandatory, while "gateway" and "dns" are optional. +DHCP currently only accepts "ipaddr" (IP address to request from the server) +and "hostname" (client hostname identify as) - both are optional. + +PPP based protocols (pppoe, pptp, ...) accept these options: + username: + The PPP username (usually with PAP authentication) + password: + The PPP password + keepalive: + Ping the PPP server (using LCP).
