I am running a few servers (apache and exim were mentioned already, also ftp and sshd), as I use my laptop as a development machine for web sites. I somehow have to tell these servers that something has changed. Also, I often use remote access to X on my laptop when I have a desktop Linux box standing around. Possibly, I simply haven't understood the issue. E.g., do I have to tell X that the IP address has changed in order to be able to connect to it from a desktop machine? Or will it find out all by itself? Greetings, Hanno
