Hi,
I tried to use (caddr_t)1 in PT_DETACH, but the code just
failed. I'm confused. It just seems the execve is stopped. Maybe I'd read
through the kernel source code to figure out where the problem is.

The TCP checksum protects more than just the contents of the packet
on the wire; it's also a (somewhat) weak check on the contents
of your packet sitting in memory, and as it's going over the bus
in your computer between memory and peripherals and for other end-to-end
sorts of issues.

FreeBSD Developers and Contributors,
One of the observations made occasionally about the FreeBSD community is
that although it has many of the benefits of a centralized development
organization, it's hard to get a sense of the architectural direction the
project as a whole is taking, as well as l

i have connected two machines by serial line.

Thank you for the tuning page! I and, I fear, others made the mistake of

sometimes quota counts do go off (for example if you quotacheck
an active filesystem).
another possiblity is that the files have been opened, unlinked, but
not yet closed. These files are still open, and correctly counted
by the quota system, but not found by find.

If i understand ptrace(2) manual page correctly,
you should use

Hi,Sorry I didn't point out that my purpose is just to

To attach debugger to a process please use PT_ATTACH

Hi all,
The ptrace(2) man page is probably outdated. I used PT_DETACH in the
following code, but it didn't run ./test. I also tried to use
ptrace(PT_DETACH, pid, (caddr_t)1, 0) to detach, but it failed too.
BTW, if I omit wait(0) and ptrace(PT_DETACH, ...) in the code, after
it runs there is a p

For a nice visual debugger, you can also give GVD (GNU Visual

Gang,
This may be my lack of understanding, but doing 'find / -fstype local' is
definitely traversing nfs mounted directories for me in -current and
-stable. The man page isn't 100% clear, but it seems to me that it should
not be doing that. My debugging got as far as determining that the

You can have it fast.
You can have it reliable.
You can have it cheap.
But you can only have 2 of the 3.
