What is the function of NM_CONTROLLED


at
Code:
/etc/sysconfig/network-scripts/ifcfg-eth0
How does it matter if it is 'yes' or 'no'
and if I delete that line what's the default? 'yes' or 'no'
and if I choose 'yes' however I have no Gnome NetworkManager what's going to happen?

CentOS6.2

Hi,

NM_CONTROLLED=yes
Will have your network interface be managed the NetworkManager daemon.

Anf obviously,
NM_CONTROLLED=no
Will have your network interface be managed the old way. It means fully configured by the /etc/sysconfig/network-scripts/ifcfg-ethX files.

I personnaly prefered the second option in servers, but the first one in desktop or laptop as it manages very well the wireless network interface.

I do not know the default behaviour.

I hope it will help you.

Regards,

Post Disabling Network Manager

This thread is a touch dated but since it may help others who like me ran into this, I disabled the network manager as per:

9.3.2. Disabling Network Manager
https://access.redhat.com/documentat...k_Manager.html

on our CentOS 6.5 system and it worked out fine. I was editing items out of net network and interface config files but this was cleaner and more system level functional way to do it.
