I have a problem setting up an ethernet link between 2 machines.

On one machine (Linux) I have a Western Digital WD8013 card and on
the other a Novell NE1000 (ka9q NOS).

On the Linux machine I have configured the kernel to use the WD card
and at boot time I see:-

---- snip ---

eth0: WD80x3 at 0x300,  00 00 C0 29 23 24 WD8013, IRQ 10, shared memory
   at 0xcc000-0xcffff.

---- snip ----

The card is hard configured for port=300 irq=10

So the kernel is seeing the card correctly.

However after configuring the interface, doing 'ifconfig eth0'
I get :-

eth0      Link encap 10Mbps Ethernet  HWaddr 00:00:C0:29:23:24
          inet addr 192.1.1.1  Bcast 192.1.1.255  Mask 255.255.255.0
          UP BROADCAST RUNNING  MTU 1500  Metric 1
          RX packets 0 errors 0 dropped 0 overruns 0
          TX packets 0 errors 0 dropped 0 overruns 0
          Interrupt 10 Base address 0x310 Memory cc000-d0000

                                    ^^^^^

As you can see ifconfig thinks that the card base address has moved.
(This was done after a reboot thus explaining no RX or TX packets)

I cannot get the 2 machines to talk to each other despite :-

/sbin/route add -host 44.1.1.1 eth0

44.1.1.1 being the ip address of the other (nos) machine.

Kernel routing table:-

Destination     Gateway         Genmask         Flags MSS    Window Use Iface
localhost       *               255.255.255.255 UH    1936   0       80 lo
g8jvm2.ampr.org *               255.255.255.255 UH    193    512     57 sl1
g0orn.ampr.org  *               255.255.255.255 UH    193    512      1 sl0

44.1.1.1        *               255.255.255.255 UH    1436   0        0 eth0
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

44.131.7.0      *               255.255.255.0   U     193    512      6 sl0
44.131.17.0     g1wkk2.ampr.org 255.255.255.0   UG    193    512      1 sl1
44.0.0.0        g8jvm2.ampr.org 255.0.0.0       UG    193    512     44 sl1

I am using Kernel 1.1.33 and the latest version of the networking tools
(1.1.27) from sunacm.

The setup on the other machine has been tested at my salt mine,
talking to an hpux box and works ok.

Has anybody got any idea as to whats going on and how to fix it.
Particularly the moving card address.

This is normal: the WD80*3 puts the 8390 chip at an offset from the base
address.  The driver uses the 8390 chip base as the I/O address so that 8390
core code can be shared among the drivers.  The WD-specific code uses an
offset whenever it accesses its own registers.

Quote:>I cannot get the 2 machines to talk to each other despite:

Errr, why are you adding a host route rather than a net route?  

BTW, you should use /proc/net/dev to check for Tx and Rx errors.

1. Setting up network - HELP PLEASE!!!

I've spent the last week reading FAQ's/HOWTO's, researching, scanning
newsgroups...etc. till I'm blue in the face.  So if there's anyone who can
help, you just may save my sanity.  Ok, here's the question:

I have four computers:

        Pentium 166 - Win95, Linksys EtherPCI II card
        486 PCI 133 Mhz - Linux (kernel 2.0.27), Linksys EtherPCI II card
        486 VLB 80 Mhz - Windows NT, Linksys Ether16 card
        386 40 Mhz - Windows 3.11, Linksys Ether16 card

I just put in all the cards and am trying to configure a network but
nothing works.  I think I kinda got the Win95 and Linux machines to
recognize the network cards but that's about it.  When trying to run the
network setup on the NT machine, it comes back saying there is a conflict
and won't go any further

        On a side note on the NT machine, it won't recognize my COM ports (with or
without the network card) can't get a mouse working.

Anyways, on the Linux machine I can do a ifconfig and get the following:

lo      Link encap:Local Loopback
        inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
        UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
        RX packets:16 errors:0 dropped:0 overruns:0
        TX packets:16 errors:0 dropped:0 overruns:0

eth0    Link encap:10Mbps Ethernet  HWaddr 00:20:78:10:38:32
        inet addr:1.2.3.4  Bcast:1.255.255.255  Mask:255.255.255.0
        UP BROADCAST LOOPBACK RUNNING  MTU:1500  Metric:1
        RX packets:16 errors:0 dropped:0 overruns:0
        TX packets:16 errors:0 dropped:0 overruns:0
        Interrupt:11 Base address:0xff80

Now, I set the 1.2.3.4 just messing around, don't know what it should be.
The card are software configurable not jumper (I know, I know so don't say
it).

IF ANYONE can give me some help, recommend a book/HOWTO that will give a
STEP-BY-STEP process on how to set-up a network with these computers,
he/she would have my undying gratitude.  I'm about to dynamite the whole
setup.

I'd appreciate responses to my e-mail address and THANKS to anyone who can
help.
