Greetings - Just when I think I've got my FreeBSD console relatively secure with xlock, someone else shows up with a new key combination to easily circumvent it... To prevent people from killing your X-Server with Ctrl-Alt-Backspace requires a simple mod to /etc/XF86Config - NoZap. Covered... To prevent rebooting your server with a Ctrl-Alt-Del requires a kernel config change. Where is this documented? Xlock is useless with the sc0 console driver, since typing Ctrl-Alt-F1 breaks out of graphics mode, back to the virtual terminal. Then one simply does a Ctrl-C and they're in... How can this be disabled? Anyone know of any other knuckle-head methods to break xlock? (besides pulling the power cord out ;v) Anyone know why FreeBSD ships with all these security holes enabled by default? I checked the FreeBSD Security web page, and there was no mention of any of these "features", or how to plug them. (Did I miss something?) Any pointers would be welcome. Thanks!
