i have a similar problem. i have two computers connected by router, and that router goes to the modem. i can only get the first comp online (winxp) and the linux one wont. i get the address for the first comp from DHCP, but the other comp keeps returnining as operation failed. does this just mean my isp hates me?

First, can you ping the other box, and your router ?
If not, check for bad cables, bad nics, etc.
Sometimes I see where a cable end has not remained
well seated in the nic port..
Do you have any status lights on the nics, and are they lit ?
If you can ping the router, then you must be receiving a lease
from your DHCP server.

What does netcardconfig do for you on the linux box ?.
Is that the function that is giving you the "operation failed"
message ?
Try ifconfig, see if you have any other devices besides "lo"

Perhaps your network card is not supported.. (usb?)

Are you truly using a router, and not a hub or switch?
Many modems will act as a dhcp server, but will only issue
one ip address...

yes, i can get the comps to ping eachother, and all the status lights say it's connected.

i messed up with my terms: it's not a router, but a hub that i'm using

i have lo and eth0 (the network card) when i put in ifconfig. the nic is not usb and seems to be supported and recognised

So, back to the modem issue...
Most modems will only issue you 1 ip address.
You need a router/gateway to nat for you, and provide
dhcp services on the inside of your network..
Use either a floppy-based router solution, with some
old "atticware" you have, or purchase a dsl/cable/router.
They are very affordable nowdays..

This will give out the ip leases your computers require to
be on a stand-alone network, and each have access to the
internet thru the back side of the router..

Computer #1 <--- \ 65.68.xxx.xxx
192.168.1.100 | [router] <-- [cable/dsl] <-- internet
| DHCP MODEM
Computer #2 <--- / NAT
192.168.1.101

There is also the possibility of using your working box as a
sharing device, but with DSL, you may need to setup shares
, as well as config your DSL netcard setup manually.

hi guys...

im totally new to linux.
just tried DSL, and its fantastic.

got similar problem with the other guys on top.
since we are using a win98(BOX1) for internet sharing on a small 8 PC LAN.

just wanna ask for clarification, cause i've tried following the instructions mentioned above, and no go.

Is there any Network Component Type ( Client ) and other networking protocols that need to be activated on BOX1 to enable another PC (running DSL on CD) to be connected to the LAN or perhaps access the net?

we have the IP addresses and DNS right, i think.

thanks in advance.
