He can still use it as long as no device on COM2 is used simultaneously
with the card. IRQs are shareable, for example, when I misconfigured a
modem once and put it on the same IRQ as my mouse, mouse worked no
problem until I tried to use the modem then it worked but the mouse
cursor locked. :) (not saying it is a good idea to share IRQs but just
making a feasibility observation)

Yes. Go to your BIOS. There are a variety of BIOSes, the most common
ones are AMI and AWARD. Depending on your motherboard, it may be
possible to disable BIOS PnP altogether and configure the slots
manually. Both may provide you with the option similar to "configure
PnP" or "configure peripherals". Get in and, if you see the "Use Win95
OS" option change it to "Use manual setup" or similar. Then there may be
a list of IRQs, make sure that you reserve two (e.g. 10 and 11, or 11
and 12 are most common choices, although 5 or 7 can be used as well but
your parallel port may be using them) for "legacy ISA" or similar.
(sorry for not being specific because there are so many different
wordings and menu sequences they use for the same things in different
versions/releases but you'll figure it out). If you run out of IRQs see
if there are any peripheral ports enabled that you don't use. E.g. don't
use parallel port? Go to "chipset options" or similar and disable it. Or
you probably have USB taking an IRQ? Disable it too. Nothing on Com2?
Another resource that can be made available. Then your cards can be
located more flexibly.

No. If you compile 3com static you won't be able to use
/etc/conf.modules file and will have to reboot for every attempt to
change settings.

Redhat doesn't use this file to load modules. The moudles are loaded on

I have to disagree with this, as the constraint in computing power moves
around, from i/o bound to processor bound to memory bound to disk bound to
bandwith bound, the "right" partitioning philosophy changes as well. I think
we are at a time where we most people have a lot of extra capacity in their
CPU's (most of the time anyway), it makes engineering sense to download some
of the processing chore to the less stressed CPU, particularly if this can
bring the price of the peripherals down. System partitioning does not have
hard rules such as "It's not the OS's responsibility", granted modularity
should be sought after, but other things do enter the equation. Also,
remember that 3COM (and others) are in business to make money, not to cater
to "fringe" markets, I don't blame them for producing the WinModem, It's a
GREAT idea on their part, I do blame computer makers for not clearly stating
that its what in the box when you buy it clearly stating that you *want* to
install Linux on it! We might be unhappy about it, but think of how many
people have gotten access to the net with the savings that WinModem's
produce!

card, and internet interface with PPP. MS windows is more friendly which I
don't have any problems but it is not stable. I have gone thru to read

Subject: Strange NFS problem
Date: 14 May 1999 08:54:01 GMT
Hi all,
I have 3 PCs running RedHat linux. 2 of them are installed in a
mobile robot and they communicate with the outside world via a pair of
wireless bridges which is connected to our department network. Oneof
the "mobile" PC is running RedHat 5.0 and the other is running version
4.2. The other one (running RedHat Linux 4.2) is stationary and serves
remote filesystems to the 2 "mobile" PCs. This setup works fine in the
past.
Recently, my office is required to move in a new building. I
setup the PCs with the same setting as in my old office. Strange thing
happens. One of the "mobile" PC has frequent "NFS not responding"
problem. the following lists parts of my syslog.
May 14 11:08:41 maemb1 kernel: NFS server maemb3 not responding, still
trying.
May 14 11:08:41 maemb1 kernel: NFS server maemb3 OK.
May 14 11:08:51 maemb1 kernel: NFS server maemb3 not responding, still
trying.
May 14 11:08:51 maemb1 kernel: NFS server maemb3 OK.
May 14 11:11:53 maemb1 kernel: NFS server maemb3 not responding, still

trying.
May 14 11:16:38 maemb1 kernel: NFS server maemb3 OK.
May 14 11:16:55 maemb1 kernel: NFS server maemb3 not responding, still

.......

May 14 12:10:58 maemb1 kernel: NFS server maemb3 OK.
May 14 12:11:17 maemb1 kernel: NFS server maemb3 not responding, still
trying.
May 14 12:11:17 maemb1 kernel: NFS server maemb3 OK.
..........
It seems that the PCs lose NFS linkage for a very time and recover nearly
immediately. It's strange that only 1 "mobile" PC has this problem,
although they share the same wireless bridge for communication. What's
wrong with my PCs? How to solve it?
Thanks in advance.

I have a cable modem with a linux box attached to it with two ethernet
nics. (on one the modem, on the other one my 'main' workstation
running Microsoft Willitwork?98) I've set it up to run 24 hours a day,
as a gateway/router and a web server. (or: I'm currently running
Squid 2.2 stable1, Wu-FTP 2.4.2-V17, Apache etc on Red Hat 6.0
kernel 2.2.5-15) For security i've set up ip-chains (with some help
of a friend) to run as an ip-masquerading firewall.
Since I'm only starting to learn about linux, i've had some trouble
finetuning the firewall/security settings. The port settings and other
basic
stuff are running fine, but I don't now how to protect the box against
things like the ping-of-death or ip spoofing. I've tried implementing
some rules out of the ip-chains-howto, but I'm not sure about the succes
of it. I was hoping any of you comp.os.linux.networking users would
have some more experience setting up a good firewall with Red Hat
and can give me some pointers or correct settings witch may help me.

Well, if you just want to proxy web pages then squid or wwwoffle will do
the job. Squid comes with SuSE 6.0 and its simply a matter of pointing
the client PC's browser to use linux box as a proxy. Unless you have a
particular reason for wanting a web proxy (filtering dubious content?)
you might as well go for IP masqing for added flexibility.

What you want to do is something called IP MASQUERADING. Technically
speaking, it's not 'proxy', but it does pretty much the same thing. What
happens is that your local computers all treat the Linux box as the
gateway to the Internet, and the Linux box re-writes the headers from
your local computers to reflect it's own, publically viewable IP
address.
The end result is that all your local computers can then surf the 'net,
do e-mail, etc. with very little hassle, and you only need one account
to do this. (In fact, I am now sitting on a W95 box in my living room,
connected via RH Linux 5.2 box in my computer room over a local
network)
The address translation is done in real-time very efficiently in the
background. (I get a BETTER transfer rate through a 33.6 modem
translated on a Linux box than I do with the same exact modem on the
local machine with Microsoft Dial Up Networking! - the difference is
about %15)
To find out how to do this:
http://www.magma.ca/~bklimas/FAQ.htm
Look near the bottom. It's really very easy. Execute a couple of
commands (ipfwadm) and if you want to have it done automatically, put
those commands at the end of /etc/rc.d/rc.local.
Hope this helps...

If all else fails, you should try reinstalling Win95 from scratch. I
tried to set up a simple ISDN-dialup on a Win95 computer and went nuts
about it not working until I found out that this installation of Windows
could not be forced to use any DNS server - no way. Reinstalling was the
only solution. You really oughta upgrade to Win98, too. It helps alot.
BTW: I dont think you have to set /proc/sys/net/ipv4/ip_forward to 1 on
2.0.* kernels (You didnt have to on my 2.0.34 Debian 2.0 dist anyways)

It's in section vcache. minfilecache=x, maxfilecache=x. At least on
Win98.
However you should also be able to disable write-behind-caching through
Control Panel-System-(right most card)-problem solving (translated from
german, sorry).
I certrainly don't hope that Win caches remote drives. Smartdrv always
refused that, and I thought that was pretty smart of him ;).
