Fedora / Red Hat Network Configuration Files notes

1. /etc/sysconfig/network
Red Hat network configuration file used by the system during the boot process.

2. File: /etc/sysconfig/network-scripts/ifcfg-eth0 Configuration settings for your first
ethernet port (0). Your second port is eth1.
3. File:
(a) /etc/modprobe.conf (kernel 2.6)

(b) /etc/modules.conf (kernel 2.4)
(c) (or for older systems: /etc/conf.modules)
Example statement for Intel ethernet card:

alias eth0 eepro100
Modules for other devices on the system will also be listed. This tells the kernel which
device driver to use if configured as a loadable module. (default for Red Hat)

Fedora / Red Hat Network GUI Configuration Tools

The following GUI tools edit the system configuration files. There is no difference in the
configuration developed with the GUI tools and that developed by editing system configuration
files directly.

TCP/IP Ethernet Configuration

1. Network configuration:
/usr/sbin/system-config-network (FC-2/3) GUI shown here --->
/usr/bin/redhat-config-network (/usr/bin/neat) (RH 7.2+ FC-1)

2. Text console configuration tool:
/usr/sbin/system-config-network-tui (Text User Interface (TUI) for Fedora Core 2/3)
/usr/bin/redhat-config-network-tui (RH 9.0 - FC-1)
3. Text console network configuration tool.

First interface only - eth0: /usr/sbin/netconfig
4. /usr/bin/netcfg (GUI) (last available with RH 7.1)
