Configuration of Network DevicesAll previous discussion on internetworking has assumed that our computers have been 'up and running', and possessed full knowledge about their networking environment. Where did this knowledge come from? The standard booting sequence for most operating systems involves the computer's hard-disk (or CD-ROM, flash-memory, ...) providing a short bootstrap program of several hundred bytes, which in turn reads the true operating system code from nominated blocks on permanent media. To configure its network connection, a client host requires (at least):
A reasonable first approach to defining this information is in a configuration file (see our labs' /etc/sysconfig/network*):
DEVICE=eth0 BROADCAST=130.95.1.255 NETMASK=255.255.255.0 IPADDR=130.95.1.8 BOOTPROTO=none GATEWAY=130.95.1.41 GATEWAYDEV=eth0 HOSTNAME=budgie.csse.uwa.edu.au
