Where are my file /etc/network/interfaces [centos]
What you’re looking for is more likely /etc/sysconfig/network-scripts/ifcfg-eth*…. it has been like this in CentOS 5.2 also.
Ubuntu (deb) – /etc/network/interfaces
Centos (rpm) – /etc/sysconfig/network-scripts/ifcfg-eth*
CentOS 6.3
Q: From where does ifconfig shows eth0, eth1… , where are they defined?
Listing of eth0, eth1… are in file /etc/udev/rules.d/70-persistent-net.rules
* It is safe to remove lines from 70-persistent-net.rules
* This file is recreated from the ifcfg-eth* files inside directory/etc/sysconfig.network-scripts if they contain onboot=1
