In general, your primary net card should be compiled in and not a module. You can get away with it if you add to your conf.modules (or modules.conf) a line like alias eth0 3c509 (or whatever the module is called) The alternative is to ensure that an explciit modprobe is done for the card before you try to configure the network. Dig around in /etc/rc* to find out where to put it.
Why should it be compiled in? surely this is a bad idea as every time you change card you need to recompile the whole kernel. On Peanut linux I have a file called rc.modules which is run by init at boot time and sets up each of the devices (network, sound etc...) This seams to work very well, not sure if its optomised for speed, but for someone like me whoes on my 5 network card in 5 months, and who had run out of PCI slots, I find this works well. I still don't understand why we don't just have the core functioanlity and enough to boot the machine compiled in and everything else put in as a module, this way it makes things very configurable, and you don't need to compile the kernel as often as you would other wise. Can anyone tell me why we wouldn't do this?
I get twitchy on this point because all my machines have two ethernet cards and I have to be very sure which comes up as eth0 and which as eth1.
With my box they come up in the order they are entered in the rc.modules file.
Thanks

PS I am currently reading writing Linux Device Drivers, which is very good and I would recommend it to anyone who wants to understand whats going on under the hood, even if you don't intend on ever writing some ode.

Good grief! I did this and it showed the correct info. Strange,
I
thought, and proceeded to bring up the interface. This also
suddenly
is working. (hmmmmm) And eth0 is also showing in ifconfig.
In that case don't touch anything else. leave it and work out how
todo
a auto insmod on boot, a cludge but it'll work, that is all i have
for
my FA311.
With the 3c509 which I have all I did was putting it in and
modprobe
3c509 and it went from there, I didn't touch the settings on the
board
and from the sound of things you wont need to.
All I can think is that when i ran modconf I did two things - deleted the dummy0
module
and tried installing the 3c509, the latter which just brought up
errors
yesterday. Perhaps restarting the computer and having no dummy0
in
place caused the eth0 mod to do whatever it needed to do properly?
I have found it good to stear clear of programs which are supposed
to
help make these things easier, as they invariably never do. All my hardware was done by learning what i had and doing a simple
modprobe
for each thing, when that worked I set it all in a script -
rc.modules
- which does it all for me.
Still not pinging anything on the network though. Pinging my own
IP
shows it is using loopback, and tcpdump then shows for trying to reach anything else on the network: 13:40:32.704186 eth0 > arp who-has jenny?TCL tell TRX850/TCL (0:a0:24:2:cf:26) 13:40:35.694822 lo > TRX850/TCL > TRX850/TCL: icmp: host jenny/TCL unreachable [tos 0xc0]
what does route -n give? it could be that you have the wrong
routing
configured and need the default route to be set to something else.
Does this mean anything to anyone? Heff! Heff! A hoffable herralump! Thanks, Jenny. PS. Next time I splash out on the netgear.
Very good idea. Very easy to configure. If you are willing to
stretch
to it get a 3com card, a PCI 3com card is the dogs danglies.
Thanks
