Can not find security 802.1x authentication to connect lan in centos5

[dihingiakalpa]

Greetings to all!

We have a server for computing in our lab and we are trying to provide internet to the server through LAN, and after that, we can connect to the server from our own desktops. but I am facing problems in authenticating security 802.1x in my centos 5 servers because I could not find the security 802.1x option in the network section directly. can anyone tell me how I can configure it?

When I connected to another machine having the ubuntu20.04 version, I got the security 802.1x option in the network section very easily. Can anybody help me to find this option so that I can put the id and password to authenticate the LAN connection?

Waiting for responses

 - Check if these info's can be used on centos too : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-configuring_802.1x_security

Do you really want to do 802.1X on your servers? This is a very corner use-case.  Physical security should be used instead.

wpa_supplicant is the most common (only?) Linux supplicant that I am aware of.

sudo apt install -y wpasupplicant  # Debian/Ubuntu
sudo yum install wpa_supplicant    # RedHat

The configuration of /etc/wpa_supplicant/wpa_supplicant.conf varies depending on wired vs wireless and authentication protocol.

An awesome wpa_supplicant config file reference with many examples is at https://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf
