I would love a hackfest!
I think learning about tools to help you protect your data ... or better
yet finding out how safe your data currentlyu is, would be both fun and
informative.
Cheers

I have gotten both vpn's coexisting nicely with each other. I can now connect to my desktop at work via vnc. It looks like I can now remove my windows partition...YEA!
Now for my final issue. I have not been able to configure my cisco vpn to allow me access to my local lan when connected the vpn is running. This is proving to be most inconvenient because I do have a web server running that is accessable to the outside world. Unfortunately the webserver is unavailable when the vpn is activated. I am thinking that if I add a second nic card to the box and configure it properly that I should be able to have one card handle the webserver traffic and the other card will handle the vpn traffic. Does this seems like a sane configuration? If so can someone point me to documentation that will explain how to accomplish this.
Thanks again,
Mike

Thanx everyone for the advice on Linux for the PPC. I
ended up going with Debian, and, guided by the advice
of the installation docs that come with their dist.
for PPC, I had a very successful (lacking sound, but i
was told to expect that, besides it's a server)
installation on the G4 Mac.
Now, the only other tweak I have a burning desire to
make to this box is to configure the kernel to use SMP
for the dual 500Mhz processors. From what I've heard,
it should only be using the first one right now, and
that I have to rebuild the kernel with SMP support.
Sound right? I would appreciate any tips or help on
getting there, such as:
-> how
-> where to check to -know- that it's using
one or both
-> any other useful kernel info
anything would be great really. thanx!

Hi gang,
Well, with the 0% financianing out there I'm seriously considering dumping my current notebook and taking all my Christmas cash to get a machine that works better with linux. I'm sick of this HP buggy BIOS that won't let linux read the thermal or battery data, even with acpi, so this'll go back to winXP for my wife, we'll dump the desktop completely, and I'll get the new machine.
My question is, what's known to work with Linux. Are Toshiba's friendly? I'm not touching a compaq with a 10 foot pole, and does anyone have an HP laptop that is fully functional with linux? What about the latest Dells? Or even, gasp GATEWAY????
I checked out linux on laptops, but most of the models weren't even close so I figured I'd ask all of you...

Hi Everybody,
I've been playing with my new toy, an Epson 1660 Photo scanner, which works
very nicely with Linux.
I have noticed that photos that I scan in and then print don't look the same
as the original. I am using Xsane, Gimp-Print, and CUPS. If it matters, the
photo is 4x6 inches, scanned at 400 DPI, and printed in 1440x720 high
quallity mode. The photo was originally printed from my 3 Mpixel digital
camera (2160x1440 pixels), so I believe I've used a more than sufficient DPI
when scanning.
I suspect the problem is that neither the scanner nor the printer is perfect,
and that the cumulative effects of the transfer functions (scanner to
computer to monitor to computer to printer) are causing this. Its actually
worse if I let Xsane compensate for me with its automatic adjustments of
gamma, brightness, and contrast. Adjusting the image on my monitor screen
probably isn't going to help much since my monitor isn't perfect, nor is
there any guarantee that I have it properly adjusted.
Is there any good way, other than trial and error, to fix this? Would
generating some simple test patterns help in making the proper adjustments?
Thanks,
Andy

Hi gang,
What's your collective opinion of Toshiba laptops? Circuit City has
got a decent machine (Satellite 1415-s173) for $999 and they actually
let me boot Knoppix on it to check out hardware support (everything
worked). The only thing I'm wondering about is the battery. MY HP
laptop doesn't let Linux read the battery info with either apm or acpi,
and I think this is a function of an incredibly bad bios
implementation. The demo models at Circuit City didn't have batteries,
so I had no way of checking this bug out on that brand. Does anyone
have experience with a Toshiba laptop that has an acpi bios? Can you
relate your experience to me?
Wes
Both my video card and the onboard sound card are assigned to IRQ11, in
both windows and linux. Device Manager and KDE Control Center say that
there's no conflict. Does this make sense?
Thanks in advance,

Hi all
I wonder whether I have found a gap in availability of applications for
Linux :-(
Specifically, I have been looking for a CD encyclopedia which will run
on a Linux box (in particular a couple I set up for my two grandkids).
Wine does not seem to provide a work-around both because it does not
seem to be happy with any CD encyclopedia and because it would require
buying Win* to get the CD stuff installed (and neither computer is worth
as much as Win* would cost).
I tried searching for Linux + Encyclopedia but that just gives me
encyclopedias about Linux. A search for CD + Encyclopedia gave a
reasonable list but none runs under Linux (as you might expect, all run
under Wintel and a few on Macs).
Does anyone know of a general CD encyclopedia that one can use with Linux?
doug
PS The grandkids take to the linux boxes quite naturally. I showed the
older one how to type "lpr -Plp3 filename" to print a file. He later
reported that he tried it on his brother's box but, since it was a
second computer and Q comes after P and 4 comes after 3 he used -Plp4
(obvious isn't it:-) ) and it worked! :-)
