If all you need is a firewall, then I would recommend purchasing a $25-50
box, rather than using your computer. For example, I use a BeadleSoft
Firewall with several hubs scattered around the house. Under this
configuration, I have had no problems whatsoever. Ports can be assigned to
internal IP's or you can assign one IP to be the sole contact to outside the
firewall.
I hope this helps.

I am a linux newbie and desperately want to avoid Windoze . My Redhat 7.0
installer finds both my 3com905b-tx-m's and allows me to
configure them.
But after installation I can only ping the bottom card though ifconfig shows
both cards there. I have another disk and installed Win98 on this machine
and both cards work then, thereby proving the Asus A7V133 motherboard, irq's
and nic's are ok. Any thoughts appreciated.

What version of XF86 do you use.
3.xx configfile is /etc/XF86Config
4.xx configfile is /etc/X11/XF86Config
That's how it is here.

Which distribution are you using? Did everything work from the outset, or
did you have to search for, install, and configure stuff? I've been looking
at used T20s, but the A series seem just as nice. Of course, I'm looking
for an easy recipe. I'll buy or install whatever gives me a working system
with the least amount of work. I do like the Thinkpads, though, and I'm a

I have an old 486 25sx with 16450 serial and ethernet.
I would like to use it as a gateway to my home computers, but I remember
that 16450 serials are not enough for a 56k modem.
Is it true?
New kernels have a solution?
Thanks in advance for any reply.

It's too bad that you only gave numebrs on MySQL, which doesn't allow us

You're either confused. I was talking about web-serving hits, you
were talking about queries. Apples to oranges.
Besides, even if I assumed that the two were equal (which they certainly
aren't), comparing his numbers to the numbers of anyone else is flawed at
best.

Your "benchmarking" test makes me laugh. It embodies all that is foul
in the MySQL benchmarts that I've seen.
You chose two isolated cases, choosing only those where MySQL has an
advantage. Furthermore, at least one of the two does NOT isolate the fact
or that you are trying to benchmark. You did not give any information
about configuration or tuning. In short, your benchmarks are unreliable.
Perhaps, in the future, you could perform tests in a fashion closer to
how Great Bridge did - when MySQL appeared like it truly did suck, they
let the MySQL folks come and tune and configure it optimally - after which
it did much, much better, and was a lot closer to what a person could
expect in the real world.
MySQL does have it's merits. It's too bad that it's proponants so
often use faulty testing methodology to promote it.

yup, it's true, you need the 16550's for a 56k modem to run
at max speed. But you can still use a 56k on a 16450 serial port.
I think the max you'll get is 33.6k of a 16450, but I could be
wrong, might be only 19.2k.

Nope, it's a hardware limitation, it has nothing to do with the

No software will fix this for you. Examine the card, if
you like, to see if 16450 is in a socket;if it is, you could
change it for a 16550A to handle the high speed.
If not, you could change the card for one with
a 16550A.

I want to try to set-up a h323 to idsn gateway. I havn't got a isdn card.
Since isdn is digital I think you can make voice-calls with any isdn card.
Is this correct?
So, which cards are good supported by Linux and not to expensive?

Date: Wed, 13 Jun 2001 23:30:15 +0200
Hi I have a Asus CUV4X-D motherboard, there's working great under windows
(ME, NT & 2000), but if I try to install Any of the bigger linux
distributions I'm getting 3 errors.
The first look like this "Unknown bridge expects transparant" and then it
continues to load Linux so I don't think it's a big problem.
The second says "Unknown IO-APIC" and then the computer stops, I have found
out that this error can be solved by changing the value from "MPS-1.4 to
MPS-1.1" compliance in the bios but would hear if anybody knew a workaround
on this without changing the value to 1.1
The third says "Can't reserve int 0 to eth0" which results in my network
doesn't work, and I have tried with different network cards in different PCI
slots without any difference at all.
So maybe someone could tell me how to get linux to run on this computer.
Thanks

From what I've heard, Alan Cox is working on it. Expect an upcoming
kernel to support it more fully.

I've had a similar problem where I disabled the onboard parallel port to
save an IRQ, and an ethernet card used that IRQ - but the parallel port
wasn't completely "disabled", and the ethernet wouldn't work. I enabled
the port again, the ethernet card took a different interrupt, and things
worked fine. I don't know you've tried those tricks or not, but hey,
maybe it will help.
By the way, these boards are very fast and efficient under Linux, even
with MPS 1.1. Two of my front-end servers run dual P3 650's in SuperMicro
boards, and two more run dual 833's in the CUV4X-D boards. Even though
the CPU's are only 28% faster and the FSB 33% faster, they handle at least
50% more traffic than the machines with the 650's.

Hmmm.. I didn't know that the 2.2.x kernels supported raw filesystems.
If it does indeed support rawfs, verify that you have the options
compiled into the kernel.
