Hi there, I was running FreeBSD-3.3 -STABLE today (as usual) and was running XFree86 X11R6-3.3.5, and WindowMaker window manager,and a couple of clients, like Netscape 4.5 and unix Cockpit. I was merely downloading some of the ports and was not compiling any code that may crash the machine. At the moment I was clicking the mouse to shift from one desktop to another the whole machine was frozen. No keyboard, no mouse, unable to even kill the X window system, and ctrl-alt-del was inoperable. The only possiblities that I can think of 1. the Window Maker contains a really bad bug. (I wonder if this could crash the FreeBSD) 2. the Mouse Interrupt came at a really bad time. (This may crash the machine on any OS, but how or why this happenend, and is this reproducible, I am not sure ?) 3. Someone has caused the machine to freeze deliberatley over the internet. (I have Pentium-166, with the work-around F00F bug installed.) I wonder (too long), about the possiblity of using this bug, or another way to freeze the machine by a "denial of service" attack. and I also wonder if there is something I should setup to at least give me some kind of logging when I reboot. Eng. David Greenman is encouraged to feedback on this, and all comments are mostly welcome. thanks in advance. ===== MAY THE FORCE BE WITH YOU. __________________________________________________ Do You Yahoo!?
