Cannot find an eth0 interface..

hi. i'm attempting to install arch linux on a ibm thinkpad 770z. my computer doesn't boot from cd so i'm am using boot floppies. i have a "xircom ethernet card" which is this module (pcnet_cs) i believe. i've loaded the pcmcia_wlan.img file and the ethernet.img. i manually loaded the pcnet_cs module using modprobe. but it still says 'cannot find an eth0 interface'. i read somewhere to use the '/etc/rc.d/network restart' command but it cannot find that filepath and you can't cd into rc.

any help would be aprreciated. thanks.

Re: Cannot find an eth0 interface..

i am not familiar with the install process your doing but to find eth0 id try

ifconfig -a

should show device if modules are loaded
then

ifconfig eth0 up

then

dhcpcd eth0

<providing you connect via dhcp
hope this gives some insight

thanks for responding.

ifconfig -a produces

lo     Link encap:Local Loopback
        inet addr:127.0.0.1 Mask 255.0.0.0
        inet6 addr:   ::1/128 Scope:Host

        RX bytes:0 (0.0 B)    TX bytes:0 (0.0 B)

ifconfig eth0 up then produce error

SIOCGIFFLAGS: No such device

now i haven't editted any config files and such yet.  do i need to edit my rc.cnf or something else for this to work? thanks so much for the help.

Re: Cannot find an eth0 interface..

Well, since the only two interfaces that are appearing are lo0 (loopback) and sit0 (used for ipv6-ipv4 tunnels), your ethernet card still hasn't been detected using the pcnet_cs module.  So, seeing as though the list found at http://pcmcia-cs.sourceforge.net/ftp/SUPPORTED.CARDS shows other different possible things you could load, I would try some of these:

xirc2ps_cs
and possibly
xircce_cs (this may not be included on the image since it isn't a very popular card)

Then, see if your card is recognized by typing in

ifconfig -a

and if eth0 is listed, then do the steps the previous poster mentioned to get it up and running.

Re: Cannot find an eth0 interface..

haha. sup thomas.

yea so i figured out which model my xircom was. found the name of the module it needs.

[pcmcia-cs driver: tulip_cb] [x86,ppc]
    [2.4+ kernel driver: xircom_cb]
    [ ethernet only ]
    Silicom FEM56 Fast Ethernet
    [ Not recommended: support is experimental and unreliable ]
    IBM EtherJet CardBus with 56K Modem
    Xircom [u][b]RBEM56G-100[/b][/u]BTX, CBEM56G-100BTX, R2BEM56G-100

the bold underlined one is my model. but where can i find tulip_cb. i just wasted a good portion of my life looking for that module and couldn't find it. i need the image file unless you know another way i can load a module without a cd or ftp.(aka all floppy) :S

thanks for the help.

[edit]apparently this package: pcmcia-modules-2.4.27-2-386
        has tulip_cb but i could only find it in .deb files. is there any
        way to load that file extension from floppy.

Re: Cannot find an eth0 interface..

hate to bump. but don't want to buy another ethernet card. there must be a way to get tulip_cb as one of my modules via floppy disk.

thanks

Re: Cannot find an eth0 interface..

what happens if you modprobe just tulip?

>>edit: if that doesn't work, try removing the card until after hw detection, then insert and manually modprobe tulip as per this post:

Re: Cannot find an eth0 interface..

modprobe tulip works to load the module (i assume it loads the module since it gives me no error and goes to the next line in the virtual console). yet ifconfig -a still shows no eth0 interface. and inserting the pcmcia card until after ethernet detection, isn't that just for onboard ethernet? because you can't detect ethernet if none is present. i'm on a thinkpad 770z. no onboard ethernet.  just a Xircom RealPort 10/100 i have in there. any help would be appreciated. thanks for the replies.

ps>>is there a command to detect ethernet?

Re: Cannot find an eth0 interface..

Bring it in tomorrow and let's look at it in APCS.  Will be easier to mess around and try stuff and we will hopefully get it working.
