Help! my Linux machine does not see the network

Post by Sanjay Bhat » Thu, 19 Jan 1995 10:15:58



Hi all
        i am having a problem getting my linux machine on our network.
my network card is about 4-5 years old and I dont know what make it
is.

when it boots up, i get the following error messages..

SIOCSIFADDR: No such device
SICCSIFBRDADDR: No such device
SIOCSIFNETMASK: No such device
SIOCADDRT: network is unreachable
SIOCADDRT: network is unreachable

my setup is as follows.. i have a machine though which i get to the
internet.  lets say it's addr is.. 201.95.82.2.  i gave my machine the
address as 201.95.82.4.  added it to the etc/hosts file on the server
machine.  ran netconfig on my machine and went through the setup.  the
only thing that i was unsure of was the netmask.  i gave it to be
255.255.255.0.  does this sound right?

        please mail me if you know what is happening here.  thanks.

I recently had a similar problem with a NE2000 card. These messages mean
that your card was not found by the kernel, probably due to i/o address
conflict.
There are two <maybe more> obvious solutions:
1. Move your card to a different i/o address, depending upon your aux
devices. do not use 0x360 since it conflicts with LPT1. Your best bet
would be 280, 300, or 340.
2. Use an older kernel, 1.0.9 for example.

Hi Sanjay,

This looks as if the Linux kernal does not recognise your ethernet card.
This may involve opening it up and taking a look at it.  Most kernels
are compiled with the most popular makes of ethernet card (NE2000, WD80*3 etc)
but will only probe for the card at specific addresses.  My WD card
wasn't found because it was at memory address 0x2A0 instead of 0x300!

Ask your administrator how your machine was set up.

: my setup is as follows.. i have a machine though which i get to the
: internet.  lets say it's addr is.. 201.95.82.2.  i gave my machine the
: address as 201.95.82.4.  added it to the etc/hosts file on the server
: machine.  ran netconfig on my machine and went through the setup.  the
: only thing that i was unsure of was the netmask.  i gave it to be
: 255.255.255.0.  does this sound right?

If your machine is using the network through DOS then take a look in it's
software setup for a small program which will be the packet driver interface.
It will generally look like this:

wd8003e -n -w 0x300 5 0xEC00

or

ne2000 -n -w 0x61 11 0x300

These bind DOS to the network card so that other programs can chat to the
internet.  The figures can then tell you the vector (0x61 is the most common),
the memory base I/O address (0x300 is common too), the interrupt (5, 11 etc)
and any shared memory pool (in this case 0xEC00).  The name of the program
should give you an indication of what type of network card you have.

If you find these out then there are some commands you can give at linux
LILO prompt or loadlin setup to stop autoprobing of network cards and
start eth0 at a specific address.

Hope this is of help

Adam

One small thing to add to this since I just ran into it on my own system:

The Slackware netconfig script sets you up properly except it assumes
you are unsing an ethernet card... device eth0.  I am using a D-Link
compatible pocket adaptor, with device name dl0.  I got all the same
messages as you did and fixed them by going into /etc/rc.d/rc.inet1
and changing "eth0" to "dl0" wherever it occurred.  Check your device
name from your boot messages:  do a "dmesg" once you've booted up, find
where it told you your network device was detected, and at the start of
the line where it did that will appear the device name.

Note that if you aren't using Slackware, the file /etc/rc.d/rc.inet1 will
be called something different... just grep anything whose name starts with
"rc" with the string "ifconfig".

1. Linux machine not seen by network (Newbie)

Hi folks:

I am a newbie, so pardon my ignorance. On my home machine, I configured
eth0 on RH 6.2 so that I can telnet, ftp, etc to our campus network. I
am now trying to have my alpha machine at the office to talk to the home
machine. When I try to telnet, the linux box is not recognized ("unknown
host"). I did read a bunch of howto's and what not, but things are not
working out still.  Your help in this regard is appreciated.

Thanks.
