That board has an fx chipset, Im almost positive that fx doesnt support
udma, I got errors when I enabled some udma option in the bios, when I
disabled it the errors went away, Im using a wd 6.4 gb drive and I know its
udma, but disabling that option got rid of the errors which is the important
thing. Try it and see if it works.

Look in the file where rpc.yppasswdd is startet, read the manual page,

Subject: Setting Up Remote Printing Problem
Date: Sun, 11 Apr 1999 14:49:36 -0400
I have two linux boxes connected via ppp. One of my machines
only has a hercules mono card and I haven't been able to find
a driver for it so I can't user the normal Red Hat 5.1 graphical
install programs. I have to install everything through the
bash shell.
I want to setup remote printing on this machine to print to
the linux-xwindows machine. How to I do the setup manually?
I also downloaded a remote printing package which includes
rlpr. When I set it up it wants to know the name of the remote
printer on my linux-xwindows machine. I don't how to set up a
name for it and also set up the proper permissions.

Subject: multiple ethernet cards
Date: Sun, 11 Apr 1999 13:53:31 -0500
HELP! Can anyone offer some suggestions on how to get 2 ethernet cards
working on 2 different subnets? I followed the multiple-Ethernet how-to and
added the proper line to lilo.conf. Both cards are seen by the kernel on
boot up
kernel: wd.c:v1.10 9/23/94 Donald Becker ([EMAIL PROTECTED])
kernel: eth0: WD80x3 at 0x300, 00 00 C0 85 48 57 WD8013, IRQ 10, shared
memory at 0xcc000-0xcffff.
kernel: eth1: WD80x3 at 0x240, 00 00 C0 B0 5B 2D WD8013, IRQ 7, shared
memory at 0xd0000-0xd3fff.
This seems to work correctly, and i don't have any other conflicts. This
computer also has ip masq enabled (this does work). eth0 can connect to
other computers but eth1 seems to do nothing. I can't ping any computer
connected to it. if i change eth1 to the default device by using "route add
default eth1" I can't connect to anything, and my ppp device stops working.
Am i missing something really simple?
Oh, i'm using slackware 3.6 with 2.0.36
please reply to [EMAIL PROTECTED], i'll repost a solution if this ever gets worked
out ;)

Subject: How do I use DHCP with a PPP connection?
Date: Mon, 12 Apr 1999 08:27:54 +0000
Is there any way of using DHCP with a dial-up PPP connection? I've
looked at dhcpcd, and it only seems to want to work with ethernet
network interfaces, not PPP.
I'm running RedHat 5.1
I'm trying to connect to a MS Windows RAS.
I've successfully created a PPP connection using kppp (KDE 1.1) and the
CHAP protocol. Well, I seem to have been assigned an IP address, and
I can ping other machines on the network using their [numerical] IP
addresses. But how do I get the rest of the information that I need
from the DHCP server... and how do I log onto the NT domain - or is that
through another package, such as Samba?
Please direct your replies directly to me, CC'ing the newsgroups.
Thanks,

First off, *don't* use the second processor -- it is more likely to cause
problems with your machine than it is to improve networking performance. The
bottleneck on a webserver is device I/O, and a second processor will only get
in the way. I believe there is a kernel configuration option to turn off SMP
(multi-processor) support. If you can swap the box for a single-processor
machine that needs upgrading, you'd be much better off. Processor *speed* is
also pretty much irrelevant with regards to networking. The only upgrade
that might improve performance is additional RAM (to aid in network buffering
and UFS caching).
Don't worry about firewalling the machine at this point, either. You can get
fairly iron-clad security by turning off *every* networking service except
SSH and HTTPD. You can accomplish that by commenting out every single line
in /etc/inetd.conf, and by deleting all of the rc scripts that start network
services (`netstat -a` will tell you what ports are open on your box). You
should install sshd on your machine, and use that instead of telnet.
Similarly, use scp (included with the sshd package) rather than ftp. If you
*must* run a mailer daemon on the machine, run qmail (sendmail is literally
jam-packed with bugs and security holes). I would suggest not running a
mailer daemon at all, though, for maximum security against denial-of-service
attacks.
Apache 1.3.6 with PHP 3.0.7 (I believe) is the most current release available
of the PHP3-enhanced Apache. I highly recommend it. PHP3 is a server-side
scripting language, very similar in syntax to PERL and C, and it is
infinitely better in terms of conserving system resources (and making your
server as scalable as possible) than cgi-bin. Avoid cgi-bin at all costs --
it will dramatically decrease the performance of your webserver (cgi requires
the forking of an additional process to handle each request -- which can put
a strain on the kernel's process tables under heavy load, and can even cause
your machine to crash). More information about PHP (and the source code for
the most recent release) can be found at http://www.php.net/. Information
about the Apache webserver (and current downloads) can be found at
http://www.apache.org/.
In order to make your website as simple to grow out onto multiple machines as
possible, I would recommend using VirtualHosts within Apache and wise
partitioning of your namespace to keep the site as "modular" as possible.
One example is this: store all images in a VirtualHost directory called
"media", which is accessed by using the name media.yourdomain.com rather than
www.yourdomain.com (all IMG SRC tags in your HTML documents should reference
images accordingly). If at some later time you decide to add in an extra
server to your web cluster, you'll be able to move the entire "media"
directory to the new machine, and re-point the DNS name
"media.yourdomain.com" to the new box. Scaling across multiple machines that
way, rather than simply duplicating the same content on two boxes, is a much
cleaner way of distributing the website, and will pay off in the long run
(trust me :).
I hope some of this information proves useful. Good luck!

Sure. Just compile both versions from the source (do a `make`, *not* a `make
install`), and then copy the binaries and configuration files into two
different directory structures ("/usr/local/web1" and "/usr/local/web2", for
example).
Incidentally, why do you need to run two versions? You can get a version of
1.3.3 that does both normal HTTP and SSL.

Hi Brian!
Well, just wanted to tell you that you lined up with the others ... i
have been reporting nfsd-bugs for almost 2 years now, but people think
that NFS isn't that important. We have a very hetergenous network here
with Linux, SUN, SGI, etc. ... I keep running watchdogs on the linux
machines to restart the nfsd after crash.
It's worst with double processor machines and recent kernels ... most
stable is 2.0.36 on a single processor machine. Kernel-nsfd works fine
with other linux clients, but is really bad with SGI & SUN ... well - in
consequence i bought 2 new SUN-File-Servers instead Linux machines. On
the other hand NFS is really the only problem with Linux - everything
else is fantastic.
My last NFSD-related problem was that the watchdogs didn't work anymore
... rpc.mountd & rpc.nfsd were running, but didn't answer any request
anymore. Best of all : this behaviour didn't stop even after
rebooting!!! ... only thing that helped, was running the server in debug
mode for a minute and then switching back to normalmode -> sounds weird,
doesn't it ?
I don't want to blame anyone who did the job and programmed nfsd, etc.
If i hadn't to administer a large network and would get paid
(re)programming, I'd gladfully accept to do the work.

I tried that - the config program kept telling me that it was a read

I had a fiddle with the legacy/pnp irq settings in the bios setup and
the card came alive quite quickly.
