Hi, I have two FreeBSD5.4 systems
with IPFilter (Version 1.8), I use them as entry for
my network, so I would like to synchronize them. I test the synchronization
with ipsyncm and ipsyncs, but I never succeed in making them work. When reading
the sources, I understood that the program read in the file
“/dev/ipsync” and then send the message. When I’ve read this
file with the command cat: “cat /dev/ipsync” there was nothing in
it, even if I send TCP or ICMP messages. When I have stopped the
“cat” process, I had a kernel failure: Kernel
trap 12 with interrupts disabled Fatal
trap 12: page fault while in kernel mode Fault
virtual address : 0x0 Fault
code : Supervisor read, page
not present Instruction
pointer : 0x8 :0xc050fb26 Stack
pointer : 0x10:0xc9d0ab50 Frame
Pointer : 0x10:0xc9d0ab50 Code
segment : Base 0x0, limit
0xffffff, type 0x1b : DPL 0, pres 1, def32
1, gran 1 processor eflags : resume,
IOPL : 0 And then I had no choice but
rebooting the system. Does root have the right to
read this file? Is this failure something
logical? Why is there nothing in this
file, and no synchronization between the two systems, even if I sent TCP
messages? Tanks for
your answer. Quentin Turbiez |
