The URL that Stefan posted is intriguing, however I didn't see any place
where it addressed one of the most difficult aspects of this issue: SCSI
IDs. SCSI IDs must be unique within a bus, and the host itself must have
an ID on the bus. Most hosts presume an ID of 7, and this is *usually*
not configurable. Thus, how could both hosts exist on the *same* SCSI
chain? This might present a real challenge...

You can try slowing down the speed by lowering the pppd speed option.
But the arrangement you diagram is likely to continue to be dicey even
at a lower speed. There is no error-correcting mechanism in PPP, it
checks for errors with a CRC and drops the frame if an error is present.
It's left up to the hardware or networking layer to correct errors.

If the problem is in a buffer in util and you can modify util to do
xonxoff flow control then it might work. That's a *big* might though.

Can't tell you why it's missing or even verify it is missing, ppp-2.3.4
is now rather old. The newest is ppp-2.3.9 available at cs.anu.edu.au
in pub/software/ppp and it's worth the effort to get and install.

You could access the db from a linux box using odbc type drivers as long as
the NT box is networked with your linux box (I don't know if there are
access drivers for linux but there are jdbc drivers if you develop in java).
You can't generate asp pages from an apache server though (unless you want
to write your own servlet to do it) - that's only an MS thing. You can
generate dynamic pages using jsp or cgi for example or even server side
javascript.
If you haven't already check out http://www.apache.org

IPX can indeed be routed. It's NetBEUI, Microsoft's protocol, that
can't be routed (it must be bridged). Even AppleTalk can be routed.
Also, a lot of IPX applications use broadcasts heavily and are
designed without routing in mind. So, many IPX applications do not
work well when you use routing. But, that's a different matter.

You may have blown away your /etc/host.conf file when you installed the
DHCP client. Create the file (if missing) and insert the following:
order hosts,bind
multi on
That will tell the system to consult the DNS servers listed in the

I think I read it somewhere that the alias "eth0"
is defined in the /etc/config.modules
or /etc/config.network (check) as:
alias eth0 <drivername.o>
So if you installed the wrong driver as a module,
you should be able to change the alias in that

The Cisco 675 wasn't configured for what my ISP (USWest) was expecting.
The router, as shipped, was set in bridging mode, and the ISP was
expecting non-bridged PPP with PAP authentication. There are some
instructions in an appendix of the USWest documentation for doing this
and some other things you need to do. I don't have the docs with me at
work, but I could probably walk you through it later.
Anyway I answered my own question (including the minicom one), so no

Date: Mon, 13 Sep 1999 21:08:06 GMT
I had been running a Linux 2.2.5 kernel with dhcpcd version 2.0b1p16-6. The
system ran perfectly for 4+ months. Last week it stooped working. The ADSL
(GTE for the West LA area) provider says that they have made no changes on
their end. I know I've made no changes to my box. This problem follows a
black out from the provider for 24+ hours.
Can anyone suggest a procedure for debugging my problem? I've tested that
the ethernet is OK by connecting it to my local network.
Any help is appreciated!

Your subject and your post are at odds?
rcp needs the host address in your /etc/hosts file (not in DNS).
also IF you have a hosts.deny file with ALL:ALL in it, you will need
a line like
rlogind:youraixnamehere
Where youraixname is the name or ip address of your aix machine

Subject: IP forwarding from PPP connection
Date: Mon, 13 Sep 1999 21:19:37 GMT
Hi all,
I realize that this has been beaten to death already, but I've been
reading all the HOWTO's I could get my hands on and I'm still having
trouble.
The setup is that I have a PPP server running on my RedHat Linux (kernel
2.2.5) box for the purpose of serving my Palm IIIx over the serial port.
The PPP server runs fine and the Palm networking connects to it. Once
it's up, you can ping it from the linux box. The problem is that IP
forwarding is not working, so that the Linux box is not accepting
packets destined for the Palm and routing them, nor is the Palm able to
connect to outside sites (all I've tried is Proxiweb which I've used
before).
I'm running PPP as:
pppd /dev/ttyS1 19200 :palm-hostname local defaultroute proxyarp
and the IIIx has a static hostname/ip-number (palm-hostname) on the same
subnet as the host Linux box. The ARP stuff is working since I added
"proxyarp" above as trying to ping from a machine on another subnet and
the ICMP requests make it to the local subnet (as seen in tcpdump). But
routing to and fro the PPP interface (I'm guessing) is not working.
There appears to be appropriate entries in the routing table (although I
can ping the IIIx from the Linux box, so maybe it *is* working?)
Under this situation do I need to use ipchains to set up masquerading?
Is it really masquerading as the Palm IIIx has a valid IP # assigned to
it?
Oh, I've also enabled ipv4 forwarding using
echo 1 >/proc/sys/net/ipv4/ip_forward
In any case, does anyone have any ideas how to proceed/debug this?

WHo knows? If you posted your hardware and software config maybe
someone will. New kernel? Old? Is the firewall compiled with "optimize
as a router?" Little stuff like that.
A Pentium 133 can saturate a T1 even with a fair bit of firewalling
installed, you didn't mention your connections, either. Maybe the
clients are dog slow and can only pull 27k, like running Windows or
something.

Just a thought:
Some BIOS's have a field to set if OS is PnPray or not, and if you leave it as PnP,
then
BIOS ignores PnP cards and lets OS assign settings for them upon hardware
initialization.
If I say "no PnP OS installed" then my BIOS assigns IRQ's etc to PCI devices, OS
doesn't
have to, and all seems to work well.
Have you tried this?
