LAN

I just installed Slackware. It's working fine and smooth. I also have three machines runing Windows (one XP and two 98). These are conected through a LAN. ¿How do I configure my new linux system to recognize the network and comunicate to it? it does not even recognize the LAN card. ¿did I miss something during the configuration?

thanks.

Most likely you did. Exactly what you missed is hard to say. For more specific help, please tell us:

1. What version of Slackware?

2. What version of the Linux kernel? ("uname -a")

3. What network interface card (NIC) are you using in the system?

4. How do you know "it does not even recognize the LAN card"? Just so *we* can be sure, what is the complete output of "ifconfig -a" (run it as root)?

I'm not a Slackware user myself, but there are many Slackware users here (though the holidays may keep them away from email for the next little while). If I can't answer you after you provide the additional information, I'm sure one of them will be able to after seeing it. I should mention that Slackware is in many ways different from the other main Linux distros, so the remainder of what follows is something of a guess on my part, based on the way Debian, the distro I use, does things.

I'm not sure how Slackware sets up networking these days, but the usual way with Linux is to put the information needed to set up an interface in /etc/networks/interfaces ... your NIC would be entered there as eth0. You'll enter either the usual sorts of info about IP address, netmask, gateway, and such, or you will enter here that the interface gets configured by DHCP (depending on how your network is actually set up).

If you are entering the information by hand, then you'll also want to enter the IP addresses of the DNS servers in /etc/resolv.conf ... if you are using DHCP, then the DHCP client (which might be pump, dhclient, or dhcpcd) can update this file from the lease info it gets.

The boot/init process should use this information to set up your networking. If not, you can (usually) use the command, as root, "ifup -a" to start networking manually.

Yes possably you did miss configuring the LAN when you installed slack, you also missed providing us with helpfull information.
Name and type of card. ?
{Slack version, 9.1 has a different config file for LAN networking.} Results of ifconfig -a
Does your lan use a dhcp server for configuration, or do you set your own address?.

The command 'netconfig' may help you.
Setting your device driver in /etc/rc.d/rc.netdevice should take care of loading the module for the card.

Thats about all i can say because you failed to provide the info needed to give a direct answer.

try to imitate windows programs, then the Windows community

I'm using slackware 9.1
the LAN card is an old GENIUS LAN
ifconfig -a:

link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:164436 Metric:1
Rx packets:218 erros:0 dropped:0 overruns:0 frame:0 TX packets:218 erros:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0

uname -a:
Linux Cic3 2.4.22 #6 Tue Sp 2 17:43:01 PDT 2003 i686 unknown unknow GNU/Linux

And yes, the lan uses a dhcp server for configuration (or so I understand). I have three machines conected to a hub on a PIII runing XP. The IP is giving everytime it restarts.

I runned netconfig, but never I have been asked about what device I'm using. /etc/rc.d/rc.netdevice does not exists! so I don't know how to tell the cpu wich driver to use, neither to conect to the internet through the LAN.

By the way, when I try to put a CD to play music, it does not mount it. Says "wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted file systems", but I mount the iso cd through wich I installed Slackware goes smooth. ¿is the the file system? if so, ¿wich one should i use?

Thanks a lot for answering so soon on holydays. Merry Christmas!

Then you can make your configuration by editing the file /etc/rc.d/rc.inet1.conf

Have your /etc/rc.d/rc.inet1 have execute permission ( chmod +x file )

JC> the LAN card is an old GENIUS LAN

This info most probably is not enough to tell you what module supports your card.

Do a "lspci -v" and get more detail about your card.

If you have /etc/rc.d/rc.hotplug as executable, it probably will detect your card and install the necessary kernel module when you boot.

Doesn't have to.

Just check what rc.hotplug does. It might have already done (check with the command lsmod)

Music CD's don't have "filesystems" that you can browse. An application may emulate as if they have, but they don't. Just put the cd and start a cd player program.

You will need to be more spesific, just what chipset does this card use, to be honest i have never heard of such a card name.

I have checked www.scyld.com/ (home of the linux ethernet device drivers) but i can find no mention of such a card.

Is it a PCI card or an ISA card.????
That makes one hell of a difference when trying to configure things. Does it work under windows, if yes can you place it in a windows computer and then note down its details, if its a ISA card note also the IRQ and IO address.
Every detail counts here.

If all else fails extracht the card and write down the chipsets numbers.

I posted a message about 5 days ago about troubles
setting a LAN. Well, i still having figured it out, but have detected that i installed the wrong driver for my card. I have a isa RTL8019, wich i found out works with ne2000 support. But to set it i need to know the io and irq adress... ¿how could i find them? and also, after this ¿how do i made the proper changes to my system?
I'm runing slack 9.1. the command lsmod says there is a isa-pnp (wich could be my card), ifconfig only detects a loopback (wich i don't really know what is, but is not of any help) and i have no eth0 (wich seems fine, since i have not been able to install any, but i figure i need to do so, or not?)
Thanks.
By the way, the answers i got on the last post help quite a lot, if not for solving the problem (wich was imposible since i did not ask for the correct information) for learning a few interesting things. Thanks!

try to enable pnp in kernel and include in the kernel the driver for your card (ne2000)

run dmesg and chech in the output if the kernel has detected your card. If not go to step 2 :-)
compile the support for your card as a module

reboot with your new kernel
use isapnnp to setup your card :-)
(pnpdump > isapnp.conf.sample
copy isapnp.conf.sample in /etc/isapnp.conf
and edit it to suit your needs )
then insmod the module for ne2000 with the parameters for io and int from the isapnp.conf
and then ifconfig ...

isa-pnp is maybe the module for isa-pnp not for your card you will have to have a module ne2k i think

ifconfig *doesn't detect*.
ifconfig configures network interfaces and displays information about this configuration.

man isapnp
man pnpdump
man ifconfig
might help you :-)

Found isapnptools.
did pnpdump, but don't understand what is says! I cannot copy isapnp.conf.sample here because my floppy broke down (just to add more fun) and or course don't have internet on my slack box.

It does say something like: minimum IO base adress 0x0280, maximun IO base adress 0x03e0. Tried both on modprobe, none worked (when I see the syslog no card was found with such an adress).

¿how do i know how to edit isapnp.conf.... ?

Also, on dmesg, it says:
isapnp: Card 'Genius LAN GE2000III Series Card'
isapnp: 1 plug & play card detected total.

Also, i wrote down the following before formatting windows. It was using this:

Raltek rtl8019 or compatible

	i/o interval 02c0-02df
        Memory interval 000DC000-000DFFFF

and was using a NE2000.sys file for the device

IF this card was ever installed by windows you may need to reconfigure the eeproms in the card windows has a habit of rewriting the addresses
so that olny windblows can use the card I had to do this with an asanite frindly net card what program you use demends on what card you have and from what I foung on google.com/linux ne2000 is the driver you need so this may be what the problem is

Where did you find this? What kernel is it in reference to?

I know of an "ne" kernel module (for NE2000 isa cards) and an "ne2k-pci" module (for NE2000 pci cards) ... but I've never seen a Linux kernel module with the actual name "ne2000" in any 2.2.x or 2.4.x kernel I've used.

Good comment Ray, btw the rtl8019 cards i ever used have ioport 0x300 set in them, so doing the following should detect the card;

modprobe ne io=0x300

Yeah, RIchard. Every NE2000 I ever got fresh out of the box was set to IRQ=3, IO=0x300. So this approach is always worth a try.

If that doesn't work for the original poster ...one of his messages seemed to say that the card's IO address was different under Windows ... one option for him is simply to walk up the io= line until he finds one that works. That is, try in order ...

        modprobe ne io=0x240
        modprobe ne io=0x260
        modprobe ne io=0x280
        modprobe ne io=0x2a0

... and so on, until he finds the card.

He might also change the PnP OS setting in his BIOS, to try to get the BIOS to set the card for him. This works for PCi cards, but I **think** it does NOT work for ISA cards. Still, it won't hurt to try.

He "would need" to resurve the irq for the card in his BIOS, otherwise some PCI device may grab the IRQ and render the isa card unusable with an IRQ conflicht.

I'm writing this for the archive.
Found another card (similar to the one i had, but this one works): rtl8029. To use a rtl8019 on linux you have to set it in jumpless mode. Well, i believed you did that with a software, so i looked all over, and found some commands on DOS but where not recognize by winXP. But when i took it off to install the other, it had jumpers on it.
Next time, find all the hardware specifications! i didn't have them because i was using a computer wich had belonged to someone else and had lost practically every manual. The rtl8019 sometimes is setup in extrange io's by windows (i believe someone said something like that on the list). In order for it to work on linux you must set it in jumpless mode. So, there was no way i was going to get it done!

Thanks everyone for the support. Hopefully, sometime i'll be answering this questions! :)

It looks to me if you dont understand the differance from ISA and PCI ethernet cards.

Correct thats ISA for you.

Well i can assure you they do work.

I hope that before you do go answering things like the above that you firstly know where you went wrong yourself.

Sorry but, as the saying goes, close only counts with hand granades and horseshoes ... not error messages and config files. You aren't likely to get help with interpreting this output until we can see it, not "something like" it. But see below.

OK. One possibility, then, is to believe what Windows tells you about the card and see if it works under Linux. That is, what happens if you run the command

        modprobe ne io=0x2c0

(as I recall, ne can autoprobe for the irq but not the io value)?

Do you get a failure message from the module? If you do not, does "ifconfig -a" then show an eth0 interface present? If it does, what IRQ does it report? And can you now assign it an IP address (maybe with "ifup eth0", if Slackware uses the ifup/ifdown commands that are pretty standard on other Linux distros)?

The "easy" way to do this is with the configuration program that came with (or should have come with) the NIC. Inconveniently for us, these config programs are almost always MS-DOS-based utilities (or, more rarely, Windows based). If you can still find a copy of DR-DOS or FreeDOS for download (I haven't looked for either in a couple of years, but once they were easy to find), either of them will probably run any DOS-based config program you have.

A bit harder (perhaps; YMMV) is to use the configuration checker/setter for NE2000 NICa available at http://www.scyld.com/network/ne2k-pci.html .

If you can do neither of these things ... isa NICs usually ship preconfigured for io=0x300 and irq=0x3 . So you might try disabling (in the BIOS) your second serial port (which will also be on irq=0x3), booting into Linux, then trying

        modprobe ne io=0x300 irq=0xA

Finally ... older isa NICs (including some NE2000s) get configured with jumpers rather than a config program, If you have one of them, you'll be playing blind man's bluff with the jumpers unless you can find documentation for the card.

If you have occasion to ask more questions about your NIC, please include in your message as much information about it as you know ... not just that it uses the RTL8019 chipset.

Nope. lsmod provides a listing of kernel modules, not of cards. This module is supposed to let kernels do PnP configuration of isa-based PnP hardware ... but I've never actually used it so can't help you with the details. Since we don't even know if your NIC can be configured through PnP (some isa NICs can, but many cannot), this is probably the wrong place to focus for now.

The command "ifconfig" will list only configured interfaces ... that is, interfaces that have IP addresses. To see all interfaces, use "ifconfig -a". But even this will report an eth0 interface only if a kernel module has found a suitable NIC and created the interface.

Yes. You need to insmod or modprobe the kernel module(s) for your NIC ... ne is the right one to modprobe (as I recall, modprobe will notice and load another module (8190.o,I think) that ne depends on.

Typically with this module, you do need to tell it the ioport and irq of your NIC, so a proper invocation would resemble this (with the values appropriate for your system):

        modprobe ne io=0x300 irq=0xA
