Ken Marx <kmarx@bigshed.com> types: > Is there a way to get a copy of a running kernel core image? If you've compiled with the DDB option, invoking the debugger and using the "panic" command will do the trick. Of course, you might be better off using the debugger to find the information you want, then continuing or shutting the system down smoothly. If you just want a copy of the kernel virtual memory space, it's /dev/kmem. But be carefull with it - it includes the I/O address space, so you can royally hose your system playing with it. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
