linux server setup w/MediaOne and Windows clients - how?

linux server setup w/MediaOne and Windows clients - how?

Post by Andrew Kin » Wed, 09 Jun 1999 04:00:00



I have two semi-related questions to pose, as I'm configuring my Linux
box to act as a server/gateway for my home network into a Mediaone cable
modem.

1) MediaOne and Linux: the cable modem communicates directly with the
ethernet card via the card's MAC address, but the service itself
auto-assigns an IP. Often, it seems, this IP remains static for lengthy
periods, but it could possibly change (if I reboot my Linux box, for
example [why would I do that??]) So, (a) has anyone done this out there,
and (b) is there a way to configure an auto-assigned IP address for a
NIC?
2) Linux as a router/gateway for Windows clients: I have two NIC cards
in my Linux box, and want to use this machine as a router and gateway to
my MediaOne cable modem (yes, MediaOne says it's perfectly fine to do,
but they won't support it technically). My problem is this: both NIC's
are talking to each other, but my windows 98 laptop cannot even ping the
NIC it's configured to see. All NIC's are on the same hub, including the
Win98 one. I have two subnets in my Linux box, and, again, both cards go
into the same hub. It's been a while since I've configured a network
using twisted pair and a hub, so any advice? I think I can only have one
subnet configured on a hub at a time, but again, I don't recall (I'll
try re-doing some of it tonight).

I'm sure I'm doing something dumb, but please respond with some advice.
Thanks -

Andy

What I did was to connect my eth0 card ( I had to flip those around
'cause Linux saw the wrong one first). And then I caonnecte dthe
second NIC to the hub.
That ought to take care of the ping problem if your network card is
running.

linux server setup w/MediaOne and Windows clients - how?

Post by Andrew Kin » Thu, 10 Jun 1999 04:00:00


Thanks Brian. I did try that, using eth1 on the hub and eth0 to the
cablemodem, but no success. Here's the config:

Linux eth1: 10/100 NIC, IP: 192.168.2.1 - I can ping this internally
(via loopback, I'm assuming)
Win98: 10/100 NIC, IP: 192.168.2.2 - I have the gateway configured as
being 192.168.2.1 and have tried DNS on and off to no avail.

I can't ping either machine from the other one. Maybe this is a Win98
configuration problem? If so, I'll re-post this on the win98 newsgroup.
But, I do want to ensure my Linux box is configured correctly, too.

One further question: I did uncover info on configuring MediaOne and
Linux to work via the cable modem and using DHCP as the protocol (via
another thread in this newsgroup), but now am wondering how I can
configure eth1 to route packets through to eth0 (which will be connected
to MediaOne). Since eth0 is using DHCP, do I simply configure the
routing between the two devices and leave the dest IP blank (hence,
letting dhcpd update the routing table, if it does such a thing)?

Thanks again -

Andy

1. Communication needed between linux server/client to windows client/server

Dear Linux Pros,

I want my linux system see the window 98 file system, but don't know how.
Is there any windows Linux service program or equivalent program out there
that windows can serve files to a Linux machine.

My window cannot log into my Linux neither.  I was able to run telnet and
connect to the linux system using the IP address.  The prompt comes up
nicely, but the login is refused saying password is incorrect as I try to
log in as root.

Thanks much.
