12.4 Working with Connection Profiles

So far we have explored the use of connections without explaining how a connection is configured. The configuration of a connection is referred to as a connection profile and is stored in a file located in the /etc/sysconfig/network-scripts directory, the contents of which might read as follows:

# ls /etc/sysconfig/network-scripts

ifcfg-zoneone ifcfg-eno1 ifdown-ppp

ifcfg-zonethree ifcfg-zonetwo ifup-ppp keys-zonethree

keys-zoneone keys-zonetwo

Each of the files prefixed with ifcg- is an interface configuration file containing the connection profile for the corresponding connection while the key- files contain the passwords for the Wi-Fi connections.

Consider, for example, the contents of the ifcfg-eno1 file:

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

NAME=eno1

UUID=99d40009-6bb1-4182-baad-a103941c90ff

DEVICE=eno1

ONBOOT=yes
