hi,
i have a serious problem on a freebsd 4.6 on an i386...
any time i try to use the ipfw command - even for ipfw show - the
machine crashes and reboots automatically...
the messages log file registers this:
/kernel: Fatal trap 12: page fault while in kernel mode
Jan 18 19:34:09 host /kernel: fault virtual address = 0x0
Jan 18 19:34:09 host /kernel: fault code = supervisor read, page not present
Jan 18 19:34:09 host /kernel: instruction pointer = 0x8:0x0
Jan 18 19:34:09 host /kernel: stack pointer = 0x10:0xd2ef5ea8

type 0x1b
Jan 18 19:34:09 host /kernel: = DPL 0, pres 1, def32 1, gran 1
Jan 18 19:34:09 host /kernel: processor eflags = interrupt enabled,
resume, IOPL = 0
Jan 18 19:34:09 host /kernel: current process = 632 (ipfw)
Jan 18 19:34:09 host /kernel: interrupt mask = none
Jan 18 19:34:09 host /kernel: trap number = 12
Jan 18 19:34:09 host /kernel: panic: page fault
i have linux background and used to ipchanes... but i'm new to ipfw on
freebsd.
in the rc.conf file the ipfw type is unknown which means that when
rc.firewall gets called there is no firewall rules set up... i don't
see how this will make the machine crash when i type:
# ipfw -a show
i'm thinking of recompiling the kernel but not sure if this will help....
can somebody help please....
thanks
