Solved oracle linux 9 network-scripts

[solidsnake]

Hello.

I installed oracle linux 9 to try it out. I don't like using NetworkManager and using ifcfg classic interface interface files for ip changes makes my job much easier.

In this version ifup - if down commands are not available and interfaces are not listed in /etc/sysconfig/network-script.

I can get around this by installing the relevant packages, but the enp0s3 listed in the ifconfig command is not listed under network-script. What should I do for this?

Should I generate a uuid and create enp0s3 with vi? It is a virtual server now but do you think I will have the same problem on the physical server?

Oracle9 and all other fedora/redhat based Linux's moved away from networkd to NetworkManager several years ago.
There is a wrapper script so you can run ifup and ifdown commands you can install. But those just run NetworkManager in the
background.

Thank you

For me, this will be a pain for someone who frequently changes ip or switches servers. In the old system I could overwrite files with the same name and change ip in seconds : (

nmcli con mod (connection) ip4 10.10.10.1/24

Is just about as easy as editing a ifcfg file.
I don't have to cd to the /etc/sysconfig/network-scripts directory, I don't have to use vi, and this will keep me
from making many mistakes because it checks the syntax in the command, unlike ifcfg scripts
which will let you type anything, whether it's right or wrong.

nmcli con up (connection)
nmcli con down (connection)

Is about as easy as ifup (interface)
and ifdown (interface).

For me it's faster to use nmcli ( NetworkManager ) to change ips.
