Normally, if I run sudo service networking restart
, it will take some time before it finishes.
But, on one machine, it returns immediately, and the results in ifconfig does not change even when /etc/network/interfaces
is changed. Then I have to restart the machine in order to load any changes in the interfaces
file.
I'm wondering how to debug this problem.
My OS is ubuntu server 13.10.
