Very interesting tutorial here and here
This is a UI to edit all configuration without requiring root privileges, bur probably if you are not root you won'et even be able to see any configuration values - forget about changing them:
/usr/sbin/system-config-network-tui
This is what you get:
ââââââââââ⤠Network Configuration âââââââââââ â â â â â Name eth0________________ â â Device eth0________________ â â Use DHCP [*] â â Static IP ____________________ â â Netmask ____________________ â â Default gateway IP ____________________ â â Primary DNS Server ____________________ â â Secondary DNS Server ____________________ â â â â ââââââ ââââââââââ â â â Ok â â Cancel â â â ââââââ ââââââââââ â â â â â âââââââââââââââââââââââââââââââââââââââââââââ
this is equivalent, but requires root privileges:
/usr/bin/system-config-network
They don't require a X-terminal session, they support a text-ui mode.
To manually hack the configuration:
cd /etc/sysconfig/network-scripts/
less ifcfg-eth0
DEVICE="eth0" BOOTPROTO="dhcp" HWADDR="08:00:27:29:06:6F" IPV6INIT="yes" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="ca6ef823-ed13-46ad-8a83-9d688f6cf239"
Some other "global" info is here:
vi /etc/sysconfig/network
NETWORKING=yes HOSTNAME=osb-vagrant.acme.com
"/sbin/ip -o addr" displays all IPs
to add an extra IP, you must specify an interface eth0:N where N > 0:
/sbin/ifconfig eth0:1 10.0.2.16 netmask 255.255.255.0
(there is an implicit "up" at the end)
Entering "/sbin/ifconfig eth0 10.0.2.16 netmask 255.255.255.0" will crash the NIC, removing the current primary address to replace with the new one.
