Setting your ggrock server back to DHCP so that it may get a new IP address

Grab a copy of these commands before proceeding

ip a

cat /etc/network/interfaces

cat /etc/resolv.conf

Once that is done, we need to make a backup of the interface file

cp /etc/network/interfaces /etc/network/interfaces.SP.bak

Run this command so the server is staged to DHCP an address the next time it powers on

cp /etc/network/interfaces.bak/interfaces.bak /etc/network/interfaces

NOTE:

To undo the changes, simply issue the command below which will restore the backup we made

cp /etc/network/interfaces.SP.bak /etc/network/interfaces

ADDITIONAL NOTE

We didn't bounce the networking service, which is why the changes are 'staged' - if we did bounce networking, it'd grab a new address now which is undesirable.
