Does your router allow multiple hosts on a given port?

I haven't yet created a lan for the machines connect to the hub(they don't
talk to each other). I've kinda fixated on getting them connected to the
Internet. So I don't have a lan yet just a bunch of computers connected to
ethernet hub connected to a router with no one talking to anybody. What
should I do first.

A hub means everyone should be able to talk to each other. Temporarily
assign fixed addresses in some network range such as 192.168.3.x with a
mask of 255.255.255.0 and see that they can talk to each other when using
IP addresses instead of names. Then your router would probably want
the hosts to be using DHCP, so configure that client in place of the
fixed address. But get them talking to each other first to rule out
hardware problems. The idea of wanting to connect to the Internet before
you even know if networking is working is like wanting to run in a Grand
Prix race before you know if your car has wheels and an engine. Get the
car running / networking working first - then you can worry about bigger
things like _using_ the car / computer.

Here is the ip info from the other machines.

Oh, the wonderful windoze "baffle 'em with bullsh!t" mode. And your news
tool is inserting non-ascii characters to confuse the issue further. The
host that has this line

0x2 ...00 50 ba 7d 12 1b ...... D-Link DFE-650 Fast Ethernet PC Card

has only a loopback and 169.254.0.0 addrresses. When a windoze box can't
find a DHCP server because it is so badly mis-configured, it grabs an
address on this network out of mid-air. This box can't see a DHCP server.
The second host, with this line

0x2 ...00 50 ba 8a 1e 2a ...... D-Link DFE-530TX+ PCI Adapter - Packet
Scheduler Miniport

has the same problem. So, either your router isn't acting as a DHCP
server, or you have hardware problems. WAIT A MINUTE! Did you say
a 'hub' ??? Are these NICs running in 10 Megabit half duplex mode? That's
the only way you can use a hub. For 10BaseWhatever, you need a switch,
not a hub.

Fedora core ip table

Looks more or less normal - though there should be a loopback interface as
well. What does '/sbin/ifconfig -a' show?

Suse10
I just get the loopback address

How are you trying to run this? DHCP, or static? If DHCP, it can't find a
DHCP server. Also look in /var/log/messages, and see what is happening to
the network interface at boot.
