Hi Michael,
Hopefully this will get to you. Can you provide us with IP information for both hosts? And the output of ifconfig? I think its ipconfig is the command used by the Empire? Maybe they are flashing, but the packets are not being returned. Maybe they are conflicting with each other in some way. What are there subnet masks?
Also, why are you using a hub and a switch? MAybe just try the switch alone, and/or the hub alone.
Many thanks,
Matthew

Hi all,
I am new to networking and am creating a home network. I have
a Linux box (SuSE 7.0) connected to a
Windoze NT box through an SMC EZ Switch and 4 port hub.
Linux NT |_____________Switch_________Hub__________|
I can ping each machine individually so I believe the network cards are configured correctly. When I ping the NT machine from Linux I see the lights on the switch blink in unison but get no response. Do I need a crossover cable between the switch and the Linux box or is there something else that I am missing?
Thanks, Mike

The reason I have both a switch and hub is because I have computers in 2 separate parts of the house. Ultimately I want to have the setup shown below. I am starting out by establishing a connection between Zues and Apollo. I will get back to you with the output of ifconfig since I am not at home. What is Empire?
From the SMC website it looks like you should connect any "standard"
I believe Empire, as in Evil Empire, refers to MS :-). Both NT and, AFAIK, W2K use ipconfig from a dos box. Win 9x uses winipcfg. These utilities are similiar to ifconfig in Linux although more limited in capability (no surprises there). port on the hub to the highest numbered port on the switch with a straight thru cable. If the hub has a dedicated port for uplinking (or daisy chaining or whatever else they might call it), you can connect that port to any of the other lower ports on the switch with a straight thru cable or the highest port with a cross over cable. Keep the computers on the "standard" ports with straight cables. <snipped schematic> The layout looks like it should work and there is nothing out of the ordinary with the IP assignments HTH, Tim

Thanks to all the input . Unfortunately the network is still DOA. The outut from the Evil Empire's ipconfig (Apollo) command is
Host Name: Apollo.datalong DNS Server: IP: 192.168.100.2 Subnet Mask: 255.255.255.0 Gateway: 192.168.100.1
When I run YAST2 (Zues) I get the following:
network card: Realtek Semiconductor Co, Ltd. RT8139 IP Address: 192.168.100.1 Subnet Mask: 255.255.255.0 Default gateway: 192.168.100.1 Host name: zues Domain name: datalong Name server list: Domain search list: local
Looks OK.
I get some interesting behavior when connecting to the hub and switch. I have an ethernet cable running between two rooms with wall
jacks at each end. When I connect from the wall jack to the uplink port (or any other port) in the hub the led does not light up.
The switch is an 8 port switch with 2 port 8's...the graphics on the
switch indicates one of these ports is straight thru and the other is for a crossover cable. When I plugin a straight cable to the cross over port the led lights up. When I plug a crossover cable into the straight port the led lights up, but not vice versa.
What is at the other end of the cable? This is the proper behavior if the other end is a computer or a hub's uplink port.
I think that I must have a wiring problem. Any hints are appreciated.
I agree with your assessment. The easiest test is to take the hub into the same room as the switch and use a straight cable known to be good to connect the hubs uplink port to the switch's crossover #8 port (or any lower numbered port, as they are also crossover ports). If the leds come on both devices, you have a wiring prob. (hopefully just a bad end connection, but if it's inside you might be able to use the old cable to pull the new stuff through) if not it may be a dead port. For the latter case you want to check the other ports in sequence. As you noted, check them with a straight cable on the "normal" (and crossover #8) ports and a crossover cable on the hub's uplink and the switch's straight 8. Good luck, Tim
