Red Hat/Fedora Networking

I supposed its pretty easy and difficult to network a linux machine that's stubborn. Sometimes it can be difficult to network a machine that hasn't automatically created the files with the proper scripts. From installation I like to let the machine default on network decisions to use DHCP since most scripts will execute properly. I've run into some problems attempting manual configuration during the installation.

Here's a list of commands that can be entered. Now one thing to be aware of is that if you aren't initially logged in as root, you will have to use /sbin/command to use the commands. Example: root = ifconfig is the same command as a user + su = /sbin/ifconfig.

ifup
ifup-aliases
ifup-ipv6
ifup-ipx
ifup-plip
ifup-ppp
ifup-routes
ifup-cipcb
ifdown
ifdown-aliases
ifdown-ipv6
ifdown-ipx
ifdown-ppp
ifdown-post
ifdown-sit
ifdown-sl
ifdown-cipcb

Those are a good list of scripts to use from command line. ifup typically requires that you enter a space, and then a name of an interface

ifup eth0

You can opt to use any of these commands, personally I prefer to modify the file itself.
