Subject: 100MB Fast Ethernet ISA ??
Date: Sun, 13 Jun 1999 04:55:27 GMT
Hello, all. I have a couple problems here. I have recently acquired a
few old 486's for a home network for practice. My main machine is a
P2-400, which has a Netgear FA-310TX 10/100(tulip driver) Ethernet PCI
card. My P2-300 laptop has a Netgear FA-410TX(pcnet_cs driver) PCMCIA
card. The laptop is running RH 6.0, and the tower is running Slackware
4.0 beta 3, both pretty much configured ala cookbook out of 'The Linux
Network'. When I connect the two thru a hub, I can ping btwn the two,
but the results are kind of odd. One ping will be fairly quick, say 0.5
ms, and the next one will be around 1 _second_, followed by the same
pattern until I kill ping. Has anyone ran into this before? I'm fairly
sure that I probably overlooked something on the laptop, as it has been
configured pretty much on the run when I get a chance, but I am at a
loss as to just what I missed.
As to the old 486's (and one P-60), I had intended to network them
together w/ the tower and the laptop, using more FA-310TX PCI cards.
That is, until I opened up the P-60 (a Compaq DeskPro XE 560) and
realized that it apparently doesn't _have_ a PCI slot. I really don't
want to 'cripple' my network by having part of it at 10MB instead of
100MB, plus my original Netgear FE104 four port hub is 100MB, and dual
speed hubs/switches look rather expensive relative to 100MB hubs. Is
there a 100MB ISA NIC out there that works w/ linux, and hopefully
*BSD? Or is the ISA bus speed too limiting?
Any assistance is appreciated.
Thanks for your time,
Monte Milanuk

The Linux Host 1 can only reach the 192.1.31.0 network using the eth0. In
order for it to reach 193.1.31.0 network, we have to specify the IP address

Subject: pppd without LCP?
Date: Sun, 13 Jun 1999 05:01:21 GMT
Reply-To: [EMAIL PROTECTED]
I just switched my ISP to Earthlink. I can manually dial in and see
their PPP frames begin, but once I start pppd I time out within a
minute. My log shows that LCP packets are sent but none are received.
I called Earthlink and they say that they do not accept LCP packets.
I have read all the documentation that I can find and it seems to me
that LCP is an important part of PPP and I can't find anything on not
using LCP with pppd. Can I configure pppd to NOT use LCP? If so,
how? Does it make sense that Earthlink would not be using LCP?
Thanks for your help!

Hi, I'm new to Linux. Currently, in the office, we're running Redhat
6.0 with Samba acts as a File and Printer Server, on 486DX100 with
32Mb RAM. The clients are Windows 98.
We also have a few old 486 which we'll install the Redhat to for use
as clients. I wonder if somebody can tell me what is the best network
system configuration so these old ones can participate in the LAN? I
mean is it NFS or whatever?
Thank you for your help and assitance. I am very appreciate it.

Without the use of a "forwarders" list the behaviour would be for
named to query the root name servers to find who's authoritative for a
particular domain and then query those name servers. By using the
forwarders directive you can have your local named query your ISPs DNS
servers first, before querying the root servers.
As another poster mentioned--use of the "forwarders" directive is also
covered in the DNS HOWTO.

Date: Sat, 12 Jun 1999 23:31:22 -0700
Hmmm..... I guess I was being a little vague on what exactly I wanted help
with.
First things first.
1) The kernel already has the appropriate bits installed, so there's one egg
in the basket. Lucas Bradstreet: Will the info about IPchains really help me
if I'm running RH5.2? I was under the impression that 5.2 only had ipfwadm?
Please correct me if I'm wrong.
2) I have issued forwarding policies (I also have a few books that seem to
be quite excellent as well as the How-To. It's still a bit confusing, but I
think I understand this part). Egg isn't quite in the basket, but this isn't
the point I'm at yet (I think).
3) Yes. This is easy. However, the part I want to know about is this:
If I do not have a separate firewall server, then how do I use ipfwadm (how
do I set the interfaces/source & destination) and how do I configure the
gateway? All documentation I've been able to find has been for a dual-server
setup, and that's not what I want to do right now ( I just want to get it
working this way so I can use it. Down the road I'll end up setting up a
second server for security's sake.)
Thank you for the help

Solved it. In case anyone is interested, the problem had nothing to do with the
network setup on "notey"; the problem was on "desktop".
On "desktop", the IP number was correct in /etc/hosts, and was returned
correctly via a dns lookup on "notey".
The IP was wrong in /etc/rc.d/rc.inet1
Took two days, and lots of web searching $$$ but that's what it was.

I think Earthlink is talking crap to be honest. Tech support drones
tend not to know anything except how to configure DUN in Windoze 95.
Get pppsetup (if you haven't already) from:

I connected to Earthlink a while ago using that to set up ppp without

Subject: Linux server, Win95 clients, 1 modem, PPP...a la LanBridge?
Date: Sun, 13 Jun 1999 09:06:41 GMT
I'm going to be converting a peer-to-peer network of Win95 machines to one with
a server running linux. Ideally, this conversion to a linux server will be
mostly transparent to the users of the Win95 clients.
The main function of the network at this point is to allow all the Win95
workstations Internet connectivity via a modem installed in one of the machines
(this machine is the one marked for Linux installation); they use a product
called LanBridge marketed by LinkSys which works as follows. When any
workstation tries to access something outside of the LAN, it makes the
modem-computer dial up (if its PPP connection isn't already active) and uses the
resulting PPP connection for network access. The question is whether and how
this could be accomplished if the computer with the modem was running linux, and
the computers connecting to it were either Win95 or Linux (in this case, there's
6 Win95 workstations and 1 Linux workstation). In other words, what I need is a
way to allow several Win95 workstations to use a single PPP connection running
on a Linux machine, possibly simultaneously. Anyone done this or know the
methods involved? I appreciate any feedback.
