sit0 vs eth0 ???

Hi all,

I have a very old laptop(400mhz, 4G hdd, etc) in which I installed SuSE
7.3 with KDE. Everything went very well and the PCMCIA subsystem works
fine, I can dial out with the modem card.

However, the network adapter card is another story (both, NIC and modem
are attached concurrently and I never take them out); the problem is
that I'm unable to connect to my home LAN.

Ifconfig shows me the lo device and a 'sit0' device, which I then
configured with address 192.168.20.3. I can ping the NIC, but it won't
ping my server (192.168.20.1).

If I try to ifconfig eth0 with an address, it gives me an error message
that there is no such device.

Previously, I had tried to use Yast2 to configure the eth0 device with
'PCMCIA = Yes', but to no avail.

How do I get this sit0 device to talk to my LAN, or at least set up a
normal eth0?

Any information will be greatly appreciated!

The 'sit0' interface is not what you want. It's not your LAN card.

Try removing the other PCMCIA card and rebooting. It's possible there
are only enough resources for one PCMCIA card to work at a time. If that's
not it, you have some other issue with your PCMCIA card being recognized and
the right driver loading and attaching to it.

Thanks David,

I'll try your suggestion, but under Fedora Core 3, *both* PCMCIA cards
worked fine; the overall system, however, was much slower.

'sit stands for "simple internet transition" and is
bassically a device capable of encapsulating ipv6 in
ipv4 datagrams.'

That is according to a message found using a google web search.

Clearly the device driver module for your card is not being
loaded. It's hard to say why without further information,
but you might start by doing "dmesg | more" and looking for
whatever it has to say about the card manager and any PCMCIA
modules loaded.
