Can anyone tell me: Security: Yes, it is not recommended, however, if you trust everyone who can connect to your network, then it is safe enough. > a) if this is a good idea in the first place, Depends on what you want to achieve. If you have only one screen and/or one machine with a decent graphics card then it does make sense. However, X is a very inefficient protocol. Eg. it can clog the network. > b) should I be looking at VNC instead of remote X, Maybe, but VNC puts the remote screen in a window. > c) is there another option I should be looking at, and Yes :) > d) if there is a good HOWTO on setting up whichever is the best to use > on a recent Gentoo system? I use X-tunneling with ssh. To get this to work, start with trying the following: (machineA has screen, machineB is screenless) on machineA # ssh -Y machineB then, on machineB, start the program you want displaying on machineA, for instance firefox. This is both easier to implement and also removes the security issues as ssh is encrypted. HTH, Joost Roeleveld
