X Connection Monitor
Added 2001-10-22
by der Mouse
This program monitors X connections: - It uses RFC931 to display usernames, when the client host supports RFC931. - It allows the user to freeze (and unfreeze) connections, or kill them, independent of the client, and very importantly independent of the server. The KillClient request can be used to forcibly disconnect a client from the server, but only if the client has created a resource, which (for example) neither xkey nor xcrowbar does. - It monitors the connection, and if it sees certain dubious requests (currently configurable only by hacking on the source), it pops up a little menu with which the user can allow the request, have it replaced with a NoOperation request, or kill the connection. The dubious requests are, at present, requests to change the host access list, requests to enable or disable access control, and ChangeWindowAttributes requests operating on non-root windows not created by the same client.

The xscreensaver program waits until the keyboard and mouse have been idle for a period, and then runs a graphics demo chosen at random. It turns off as soon as there is any mouse or keyboard activity. This program can lock your terminal in order to prevent others from using it, though its default mode of operation is merely to display pretty pictures on your screen when it is not in use. The benefit that this program has over the combination of the xlock (1) and xautolock (1) programs is the ease with which new graphics hacks can be installed. You don't need to recompile (or even re-run) this program to add a new display mode. Improvements to about a dozen modules, and a new module, nerverot.
