Dynamic Configuration Based on Network Domain

When a user connects to the network with a static IP address while at work and with DHCP while at home, before connecting to the network with DHCP, the user must modify configuration files (i.e. /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/resolv.conf) to specify that he will connect to a DHCP server and then he must reboot. When the user needs to connect at work with a static IP, he will need to modify the configuration files and reboot again. There is currently no way to specify this to occur automatically and, thus, avoid the modifications and reboot.

The invention is to have the system detect its network domain during the boot process and set the network settings appropriately. The advantage is that the user only needs to specify the configuration settings once and will not be required to reboot.

The invention would work by having the user specify which network settings to use based upon the network domain in a configuration file. For example, the configuration file may appear as follows:
domain austin.ibm.com {
nameserver 9.41.5.23
search austin.ibm.com pok.ibm.com ibm.com
ipaddress 9.89.3.87
subnetmask 255.255.255.0
gateway 9.89.3.1
