The idea was basically what you sketch at the end: implement a
very simple protocol which does the encapsulation (IP+UDP probably)
and retransmissions etc by itself. This is meant to be run on a dedicated
interface so we can neglect security issues.
I think there is a standard API for "console" d

Hello,
I've been working on some code to filter ethernet frames in the
bridging code.
Because this is my first real attempt in coding for the kernel,
I'd appreciate any constructive comments on the code.
Code and a few install instructions can be found on http://jodocus.org/
Thanks

Hi
I coded a syscall which fork inside kernel and launch a new process.
The unique problem I got is when the father is waiting the child process
and received a sigkill signal. It freezes the system like a while (1) in
kernel mode.
Note that a sigkill to the child process does not matter at all.

Hi hackers!
Help to understand why my rc.conf system do
not want to use more ?
Before last reboot I make next:

/etc/defaults/rc.conf

What's happen ??
I've tried to copy /etc/defaults/rc.conf from
another workable computer - no reason!

using tcp for this is I think wrong..
Use UDP or maybe even an special protocol on IP.

Folks,
Thanks for all the helpful hints. Depending on what I find when I look
at how DDB/GDB work now I will probably do the following:
A) Use UDP/IP as the transport.
Reasons:
1) Easy to write a very minimal, outside the stack, IP/UDP layer.
2) Allows debugging through routers, a

Hi List,

That depends on where they put it. If it depends on I/OKit then we
won't be able to use it easily I figure.
Thanks for
yes but we might as well be protocol compatible if possible :-)
