Say he gets a particular IP address one time. Let him note that, and configure his own machine to have that IP address statically configured in his machine (this may involve setting up a static DNS and gateway too, so it might not be trivial).
Then, if when he next connects, that particular IP address is free the remote server should simply recognise that he is using it, and not try to give it to anyone else. Since it's static on his mkachine, it would not change so long as he remained connected.
(This is exactly what I do on my home LAN, by the way: The ADSL router gives out dynamic IPs by DHCP to any connected machine that asks for one, but does not interfere with any machines that have static IPs configured in them; and whenever I connect
This is wrong. The dhcp server may not know that one of the IPs it has for the giving some one has stolen already and is using it. Chances are the dhcp server may give it to a second machine and break havoc. And if the sysadmin is any good and spots you, he/she will pour his wrath on you. And in the case that the dhcp server does notice that the IP is already in use, as it knows it did not give it, the server will undoubtedly log a security alarm. Of course, you can run away with that on a home lan. To do it correctly, at home, say, is to take note of the range of IPs that will be assigned by the dhcp server (it is configurable) and what IPs can be given as fixed. When you need a fixed IP, you take it from the range of fixed IPs that the dhcp server will not meddle with. - -- Cheers, Carlos E.
