Red Hat Bugzilla – Bug 215191
Router and DNS address are NOT required for Ethernet devices
Last modified: 2007-11-30 17:11:48 EST
When configuring an Ethernet interface for a static IP address the dialog will
not accept the data unless a DNS server address and a default gateway address
Obviously if there is more than one Ethernet interface on the system then you
do not want to have a default gateway for each one. But even if you have only
a single interface then a gateway might not be desired. There is no
requirement that a network have a router. Small networks that are all on a
single subnet without Internet access are reasonably common.
Having the number of DNS servers exactly match the number of Ethernet
interfaces is a bug in the kickstart configuration file format. Having
multiple DNS servers when you only have a single Ethernet device is common, as
is having multiple Ethernet interfaces and only a single DNS server.
This will be fixed in the next build of system-config-kickstart.
