Debugging the FreeBSD Kernel Transparently

Posted by kdawson on from the deep-juju dept.

An anonymous reader writes "To debug the FreeBSD kernel core dump efficiently, it is best to set up a remote debugging session between a development machine and the target machine, and remotely debug the kernel using serial communication. This article shows you how you can debug as many kernel images as you want; it becomes transparent to users once debugging starts, and your system's performance is not affected at all."

  1. Wyse terminals work well for this. by Anonymous Coward · · Score: 3, Interesting

    About 5 years ago I used an old Wyse terminal I got at a junkyard for exactly this job using a homemade cable, it worked beautifully. Once complete I then used the terminal to control and update the server from the living room couch.

    I also used the same terminal and SoftIce to *ahem* "debug" several windows applications.

    Wyse terminals (at least the older ones) are excellent gear, very sturdy, nice keyboards, though the monochrome monitor was a bit burnt in on the one I used. An industrial strength terminal for a rock solid OS. A match made in heaven. FreeBSD is an excellent OS.
