The computers are in a university laboratory, where students often

The problem with this plugging and unplugging is that when the
dhclient doesn't receive a lease in time, it randomly picks an
address and stays with it even then the cable is plugged later.
With this random address I can't connect to the computer remotely.
And so the idea of a static address came to my mind. But now I
think I should look into the configuration of dhclient to resolve
You can resolve this issue by setting up a long lease time and set up
static leases only - it's trivial.
This is what I have already done, but the static lease doesn't protect
me from the "unplugging problem" and the behaviour of dhclient. I
haven't looked into the config of dhclient yet, but reconfiguring it
so that it keeps trying to get a configuration and doesn't fall back
to a random IP address seems a good thing to try.
