Hi. I recently downloaded the latest version of BIND 8. The
Installation instructions say that it works with RED HAT. Will it work
with SlackWare too?
Also, I'm trying to set up a DNS server behind a firewall resolving
local names only. I'd like it to forward to our main DNS if it can't
find anything locally. I understand that this is a bit more involved.
Does anyone have any good documentation on how to do this?
Thanks

I'm surprised none of the other responses addressed the legalities of
what you're trying to do.
Have you checked with your local authorities to find out if it's legal
for you to set up a network like this?
You may find yourself suddenly in the category of being a "common
carrier", and subjected to all the red tape associated with being a
baby bell or cable company.
Of course you can just do it and hope you don't get caught.. but then
there are the civil liabilities.. like when lightning hits a tree at
one end of your network and the house at the other end bursts into
flames.
Are you going to install all the protective devices like grounding and
bonding and lightning arrestors? And carry a $1.000.000 insurance
policy?
Things to think about...
As for actually wiring a network like this, use fiber.
That will avoid the problems of ground potential differences and
lightning damage as well as eliminating RF interference.
It will also avoid the length limitations.
It will however cost more.

Subject: assigning IP address to jetdirect EX card?
Date: Mon, 29 Mar 1999 11:02:26 -0600
Greetings,
I'm in the process of phasing out our NetServer and replacing it with a
linux
box running samba. I've got it all working fine -- the only thing that
remains is the incorporation of the office printer which runs off of a
JetDirect EX (external) J2382B. From what I've read, it should only
take
an assigning of an IP address to that JetDirect card, but I cannot find
the utility with which to do this.
I've gone to the HP page and linux isn't a supported flavour of UNIX,
but
I'm sure that I'm not the only one who has attempted this with this
card.
If anyone can give me any helpful tips, I'd *really* appreciate it.
Warm regards,
-Charlie

Make sure PNP is off. Usually best to use DOS based config utility that

Then you might try adding 'append' line to /etc/lilo.conf

This is a *very* theoretical question. On paper, the max is 12 MB in
each direction for a total of 24 MB. There are many caveats with this
however including Windowing and packet size that arguably drop the max
theoretical. Check out:

Depends on the operating system running on the machines. What you are
referring to is called "load balancing" or "trunking", depending on how
it is implemented. NetWare 4.x or higher servers will do this (although
the load is only really balanced outbound). Many switch vendors have
implemented this as well. I'm unaware of any features/add-ons that will
let you do this with WinNT, Mac, Linux or Sun. I would expect you would
see it on Linux before anything else. ;)
Cheers,
Chris

Most of that was written by slackware/debian users and won't fit RH or
Caldera or Suse. It's sorely out of date in many cases, with no hope of

Probably or what. No version is easy. Some are easier than others. Some
are more powerful than others.
Want some fun? Try installing Debian from a SCSI cdrom using an older
Adaptec board and an old NEC drive. After 3,011,567,3955 tries, I gave
up and installed Caldera. Debian also couldn't locate my nic, even
though I told it everything it could possibly want to know about the
board. Probably more problems during the install but, I couldn't get
very far in the 19 hours I spent on it.

suspect the video card is not a quality card...)
Just make sure before you get the components. Verify online that they have linux
compatibility. Or if you are willing to have it sit and not use ti to its full
potential til the drivers are available (this i would leave for the DVD and
sound cards...) No harm in waiting for the SB LIVE 256 support to come out, you
should be able to get it to run as a 128...
As for a monitor, i would suggest again, wait a few months. See what happens
with the new flatscreen LCD monitors. Much less desktop space used.

You don't report whether the EtherPros are running at 10Mb/s or 100Mb/s.
If both nets are 100Mb/s, you could be running out of horsepower, especially
in an environment that has lots of small packets. Each packet has to be
handled
twice by Linux (once at receipt, and again for transmission), and the
interpacket
arrival time for short packets can be around 5 usec. This could cause you
to see
a lot of dropped packets (probably this will show up as input overruns).

That's the default I think; it's what I tried first. However it didn't work
and the port scan showed 1812 was running radius auth and 1813 for
accounting which would seem pretty definitive. Besides we're dealing an NT
program here, what would standards have to do with anything? :)

Yes that's been done too. Also if the radius server was rejecting the
packets sent by the linux box I would *expect* that it would've mentioned
that in it's debug mode, it doesn't show anything to indicate the linux box
has contacted it. I could be wrong on this but I'm guessign linux is the
culprit here.
