We could have wifi, team, bond and others. Let’s have a quick look to most important of them. We realize that some properties have different values and some others don’t exist if it isn’t necessary. Ι ‘ll show you two of them from my machine, one with a dhcp configuration and one with static ip. When we create a new connection or modify an existing one with nmcli or nmtui, the results are saved here as connection profiles.
Ifdown-ipv6 ifdown-tunnel ifup-isdn ifup-TeamPortĪs you can see here the files with name starting with ifcfg- (interface configuration) are connection profiles. Ifdown-ippp ifdown-TeamPort ifup-ipv6 ifup-Team Ifdown-eth ifdown-sit ifup-ib ifup-routes network-functions-ipv6 Ifdown-bnep ifdown-routes ifup-eth ifup-ppp network-functions Ifdown ifdown-ppp ifup-bnep ifup-post init.ipv6-global Ifcfg-lo ifdown-post ifup-aliases ifup-plusb ifup-wireless Sample Output ifcfg-enp0s3 ifdown-isdn ifup ifup-plip ifup-tunnel We find them in /etc/sysconfig/network-scripts directory. We call these files also as “connection profiles”.
They need us to make a configuration file to tell them how to achieve network connectivity. It is simple to understand that our devices by themselves can do nothing. In the last column we see our configuration files which is used by our devices in order to connect to the network. Naming depends on the type of the network card (if it is onboard, pci card, etc).
In your machine you could see other names. We have one network cards with name enp0s3.
No need to use the Epson driver.A good starting point would be to check our devices: # nmcli dev statusĪs we can see in the first column is a list of our network devices.
