This section describes the misc. stuff involved in networking. XOK supports multiple ethernet interfaces and exopc comes with the typical ifconfig, route etc tools along with an arp demon and DNS resolver.
The IP address of the machine will be determined by the first process. This process then proceeds to initialize a global interface table that contains basic ``ifconfig'' information, like physical interface number, ip address, ethernet address (cached from sysinfo), netmask and flags. Programs use this information to know if an IP address is on the local LAN or remote; if it is on a remote location, then they look in the route table for the route.
ExOS uses the same routines used in OpenBSD. You just have to make sure that all the networking code is ready by the time you need to resolve your first address.
