New to the list...

[IT3 Stuart B. Tener, USNR]

List members:

	I am new to the email list, and would like to ask a few questions.
Is there a website that allows me to set and control the options I have for
this email list?

	AX.25/Linux questions!

	I have been a System Administrator and a Ham for over 15 years each,
and I am trying to get AX.25 + Linux working, so here we go. By the way in
case it interests anyone I have read the AX.25 FAQ (did not understand all
of it, but I did read it). I think the FAQ is very poorly organized but in
terms of the technical data, I understand it.

	Now it is my goal to get Linux running using the AX.25 drivers. When
I do I, eventually I would like to build my own TNC using one of these
single board computers, such as openbrick. But, that is after I make it work
on the desktop I have (and my laptop).

	I have a few questions for you now:

	If my goal is to configure TCP/IP over a soundcard modem using
Linux, what do I need to get working (using the AX.25 FAQ as a guide)? For
example it is my understanding using a TNC, you would put the TNC into KISS
mode to allow TCP/IP to avoid the AX.25 level. Then setup (in the old days)
KA9Q to do the TCP/IP stack.

	The first thing I would like to accomplish is making the PC act as
an AX.25 TNC using the soundcard. Once this works (for basic packet
operation) then I would like to configure the system to:

	(a) Run TCP/IP, using the soundcard as the modem
	(b) Run TCP/IP, using an external TNC in KISS mode (on /dev/ttyS0)

	I did the modprobe of soundmodem, and then tried to issue the
sethdlc command, but after doing so I got "no such address or device" when I
did an "ifconfig sm0 up".

	How can I verify what the IO, DMA and IRQ of the sound card is, if
it is built into the motherboard, and the BIOS offers now way to set those
for the card?

	Other than the soundcard not being set right by sethdlc, I am lost
as to what is wrong. Any assistance you can offer would be well appreciated.

	Thanks in advance.

You may be able to get this information from /proc/pci.

As well as the sound card parameters, you use sethdlc to configure how
you will key the radio - serial port, parallel port or MIDI port. I
think an error with those settings can also result in an error at 'up'
time.

Perhaps you should try the AX.25-HOWTO first.

Well, what kind is your soundcard? Notice that the kernel 
soundmodem (the module you're trying) only supports Sound 
Blaster o Windows Sound System compatible cards. Many new 
cards are not suported by it.

But haven't you heard about the userspace soundmodem? It is 
not a kernel module, it's a usermode program, it's easier to 
configure, and (the most important thing) it handles the 
soundcard through OSS, so it works with virtualy every 
soundcard supported by OSS.

It's likely that your onboard soundcard will not work at all 
with the kernel soundmodem.

Try usermode soundmodem, and tell us.

That is created by the mkinitrd script on the initrd.  So if you ran the
patched mkinitrd script, you are done with that step.

If you want an easier install (and more recent code), check out
ftp://people.redhat.com/dwalsh/SELinux, which has userland RPMs and some
sample scripts, and http://people.redhat.com/arjanv/2.5, which has
kernel RPMs.  But you'll need to upgrade to Fedora Core as your base
platform to easily use these RPMs.

We hope to have an updated release on the NSA web site soon; many things
have changed since the October release (which is what you are using). 
Note that the modified initrd is no longer necessary with the latest
code; Dan Walsh of RH created a patched /sbin/init program to perform
the initial policy load.

Is the sysvinit patch available for download anywhere? I only see srpm's in
Daniel's directory. Is it likely to work with the current lsm patches or
will it require the new kernel patches when they come out?

Thanks
Stephen

Hi,

Is anyone working on a MacOS port of Xen?  I am looking to use the Core Duo VT functions to get Xen working on the Mac. If this is currently being done, could someone point me in the right direction.

Thanks

The problem would be exactly how to boot Xen on MacOS...

MacOS would strictly want to be ported to run on Xen, which would not be 
particularly easy without the source.  It used to be the case that you could 
compile xnu (the Darwin kernel) from source and boot MacOS using it.  This 
worked on PPC, and would mean you'd just need a port of xnu to Xen.  I don't 
know if that fits with Apple's boot-time restrictions as implemented on x86 
Macs.  I don't know if they're going to want to make it easy to recompile 
your kernel anymore.  Maybe that scheme won't be possible.  In which case you 
might either:

* Boot Xen / XenLinux first, and then boot MacOS in a VT virtual machine, 
giving it privileges to access whatever it needs to verify it's running on a 
real Mac (not clear to me whether this is possible in a non-hacked way, but 
wouldn't seem to necessarily violate Apple's "Only run this on a Mac" 
license...)

* Boot MacOS first, then somehow load a hacked Xen as a .kext, which would 
then quietly steal control of the hardware from the MacOS and use it to run 
virtual machines - more similar to how VMware / coLinux implement their 
low-level functionality.

Also, I don't know if the core duo in current Macs has VT enabled.  It needs 
to be enabled in the BIOS, by the manufacturer / admin anyhow.  You should 
check whether the functionality is *really* available yet.

Cheers,
Mark
