On Debian - Say I have a network card eth0 on my /etc/network/interfaces file, and I want to add a new interface to it (that uses dhcp). Is it necessary to restart the networking service (/usr/sbin/service networking) when I do this in order to bring the new interface online? Or is there anything else I have to do after I edit the file?
I know that editing, say, dhcpd.conf requires dhcp to be restarted. Wasn't sure about interfaces.
Thanks for your help, from a developer pretending to be a sysadmin for a day.
