Hi,
I'm currently reading chapter 13 of the RHEL Deployment Guide, and taking some notes. I have a few minor questions:
/etc/sysconfig/network
According to the doc: "This file specifies routing and host information for all network interfaces."
Here's how mine looks like:
--8<----------------- NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=fujitsu.zuhause GATEWAY=192.168.1.254 --8<-----------------
NETWORKING_IPV6= -> I wonder if I can switch that to 'no', since I simple don't use IPV6. Will some apps mysteriously refuse to work when I do this? (You never know...)
HOSTNAME=... -> this looks like a redundancy with information provided in /etc/hosts. So what is it for? Can it be left out?
GATEWAY=... -> another redundancy, since it's also to be found in /etc/sysconfig/network-scripts/ifcfg-<interface>. Leave it out if it's in the individual interface scripts?
More questions to come, but here's a first bunch :o)
Cheers,
Niki
PS: I've started on Linux with Slackware (7.1), hence a habit of configuring my system with Vi rather than some configuration helpers. Even if they do the job as good, it's just a matter of personal taste and habits.

That can be safely switched off, yes.

NO. There are probably several parts of the system relying on the hostname of your machine to be in that file.

This is the *default* gateway, which should be referenced here.
