Comment 38 for bug 1301015

I have changed my static ip configguration in /etc/network/interfaces.
But i was unable to use any of the command to bring my interface up and running. It's totally useless thing what i have found.
I tried the following options. none of them worked.
1. sudo /etc/init.d/networking restart
2. sudo ifdown eth0
3. sudo ifup eth0
4. sudo ifconfig eth0 down
5. sudo ifconfig eth0 up
but none of them reloads the /etc/network/interfaces
