The computers are in a university laboratory, where students often
unplug the lan cable. Then they plug the cable again after some
time, and unplug again.
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
the problem.
You can resolve this issue by setting up a long lease time and set up
static leases only - it's trivial.
