Network is unreachable, please help

I have Fedora Core 1 installed. It is connected to a switch (hub). I
know the hardware (NIC and cable) is properly connected because the PC
(running Windows 98SE) was on the network last week.

I verified the success of the driver install for the eth0. I looked
at the bootup messages which shows

eth0: VIA VT6105 Rhine-III at 0xf800, xx:xx:xx:xx:xx:xx (correct MAC
address omitted)

eth0: MII PHY found at address 1, status 0x786d advertising 05e1 Link
45el

I ran lsmod and this shows two entrys...

via-rhine 14384 1
mii 3736 0 [via-rhine]

I ran ifconfig and this shows the correct HWaddr under eth0. And the
following...

lo Link encap: Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

TX packets:59 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:7071 (6.9 Kb) TX bytes:7071 (6.9 Kb)

Then I tried to ping one of the two other machines on the local
network.

ping 192.168.0.1
connect: Network is unreachable

Last week, the Windows98SE showed an IP address of 192.168.0.3.

I tried running
redhat-config-network
and this shows a static IP address of 192.168.0.1 (which is actually
the IP address of one of the Win98 machines already on the network!).
Use DHCP [ ] is not checked. I tried checking DHCP, but this did
not help.

I much appreciate your help/suggestions, as I'm no network guru !!!

Thanks and Happy Groundhog Day!

But it didn't show eth0, which means the interface is not up. Try using
"ifup eth0", and if that doesn't work, you need to configure the
interface.

Each IP address must be different and unique on the network.

Did you have a DHCP server?

If it still doesn't work, post the output of "ifconfig eth0". Don't
bother blanking anything out, it doesn't add anything to this
conversation and can hide problems.

There is no DHCP server on the local network. Not sure if I need to
tell Linux the Workgroup name of the network to see the other (Windows
98SE) machines onthe network, nor do I know how to do this? When I
ran redhat-config-network and changed the static IP address from
192.168.0.1 to 192.168.0.3, it seems like this IP addr won't "stick,"
then still reports 192.168.0.1. And, I assume I don't need to
reboot Linux for this to take effect. By running
redhat-config-network, is this "configuring the interface?"
Thanks

Here's some additional information that may/may not help...

you either need to set different static addresses on each card, or
configure a DHCP server to hand them out for you.
in your case, keep 192.168.0 as the first three numbers on the card,
but make sure that each machine, and each network card on each
machine, has a different number in the last octet of the address.
e.g. 192.168.0.1, 192.168.0.2, 192.168.0.3, with a netmask of
255.255.255.0. also, make sure you have more than one machine on
before you ping its address otherwise you won't get a reply! you can
always test if IP is bound to the card properly by pinging the
computer's address locally.

type
ifconfig eth0 192.168.0.2 (or another uniqie address as explained
above) netmask 255.255.255.0

then type
ifconfig eth0

what do you see?

I edited /etc/sysconfig/network-scripts/ifcfg-eth0 and changed

192.168.0.1
to
192.168.0.3

With this change, I was able to ping the other two (Windows 98SE)
machines on the local network. Plus, I can now ping these two Windows
machines from Fedora! Success!

Basically, I got the idea from
http://www.maths.cam.ac.uk/lapnet/rh7x/
which describes changing this script, which I did using VI, since I'm
not using a GUI.

I still don't "see" the Fedora machine in Network Neighborhood (am I
supposed to?), and still trying to figure out how to do a remote login
to Fedora from either Windows machines.

that's good. it has the same effect as configuring them manually like
i suggested in the last email. now it does the same thing through a
script. unique addresses are critical to IP functionality.

no. look up Samba. you need fedora to speak SMB as a client. if you
want the windows machines to see fedora, configure it as an SMB
server.

for a real basic, low security option, try telnet 192.168.0.3 if your
telnet daemon is on.

good luck
