For some reason, ifcfg-eth* under /etc/sysconfig/network-script were deleted.

Is there any tools that could detect network interfaces and re-generate these files?

Another question :

If I manually added ifcfg-eth0, is there any method to make it work without reboot?

I tried "/etc/init.d/networking restart", and it doesn't work.
