Thx for your answer.

this script just uses /etc/sysconfig/network-scripts. All my interfaces
work fine. My problem sit to understand the intereaction between
/etc/sysconfig/networking and /etc/sysconfig/network-scripts. When I
boot the network script read and set up my interface with the
/etc/sysconfig/network-scripts files. So why are there
/etc/sysconfig/networking ? how these /etc/sysconfig/networking files
are used ?

THx a lot.
