It turns out that the answer was to create an /etc/host.conf file
containing:

Subject: What is a winmodem
Date: Mon, 08 Feb 1999 16:31:24 -0800
I heard that if you have a winmodem you cannot use Linux for PPP. How
can I determine if I have a winmodem and what is a winmodem? I'm trying
to set up PPP using Linuxconf, but am not succeeding. I believe the
problem lies with the modem configuration.
Thank you,

Subject: ANNOUNCE? DRAFT 'Home Networking HOWTO'
Date: Tue, 09 Feb 1999 20:40:24 +1000
I am trying to draft a HOWTO to cover the basic of pieceing together a
home network based aroud a linux 'server'. AFter seeing numerous 'how do
i ...' questions centering around connecting linux/95/nt machines on a
home network, i thought there might be a need for something like this.
The ground i was considering covering was:
Linux server:
file serving (samba)
mail server (pop + sendmail + fetchmail)
internet gateway (firewalling, ip_masq)
dns caching
Clients (to take advantage of filesharing, mail, web, ftp, dns, etc)
DOS
Win3x
Win95
WinNT
OS/2
Mac
I've pieced together a very rought draft full of holes and missing
sections, which can be spotted online at:
http://www.powerup.com.au/~sfagg
Currently it's getting update rather randomly.
For this to succeed i need:
1. encouragement
2. feedback
3. volunteers (for the mac, os/2 and perhaps dos clients)
4. some one to check my work
Any takers?
Is this all covered in existing FAQs/HOWTOs?
Anypoint in this?
Any potential audience?

Reply-To: [EMAIL PROTECTED]
Hi all:
I'm a relative Newbie, having only installed Linux (SuSE 5.3) in the
past month. I'm starting to get comfortable with it now, and would like
to start experimenting with networking. The problem is, I have all kinds
of old, weird hardware, and need some advice on which would be the best
way to approach it.
I have Linux running on 2 machines now: a Pentium 133 w/16 MB of RAM,
and a 486/33 with 20 MB. I also have a Toshiba 486/75 laptop (8 MB) and
could cobble together a 386 (up to 8 MB, maybe) out of spare parts. I'd
rather not start messing with the Pentium (my main box, and if I screw
it up, I'm up a creek) until I have a pretty good idea of what I'm
doing. I also have 3 ISA Ethernet cards (2 Etherlink III and one
Etherlink II) I could install.
I'd be most comfortable setting the 486 up as the server and linking one
of the other boxes to it as a client. I have about a GB of disk space to
play with there, and considerably less on the other 2.
Problem #1: Installation. The Toshiba has a really off-brand PCMCIA 2x
CD-ROM. I bought it overseas and can't even find Win95 drivers for it.
The company that made it (TXC) has no web presence as far as I've been
able to determine. The DOS drivers are made by Oak Technologies and when
I wrote them, they said to contact the OEM. The 386 wouldn't have any
CD-ROM at all, and at best two 40 MB HD's.
Am I better off trying to get the CD-ROM working on the Toshiba, or
installing a minimal Linux from floppies on either box and then doing
the rest over a network connection? I could be willing to spring for a
PCMCIA NIC for the Toshiba, but don't want to spend any more until I
know what I'm doing (and what I want to do in the near future).
I also have a SyQuest EZflyer 230 MB parallel port drive. I could try to
do an installation off that too, but they filed Chap. 11 in Nov. so
tech. support there isn't going to be too easy to come by. I haven't
even tried to get it mounted on either of the working boxes yet.
This is getting a little long, so I'll hold other problems for a future
post.
An e-mail repy would be appreciated as I don't get onto the newsgroups
as often as I'd like.

The ISP is not responding in any way to the initial LCP requests and
pppd is timing out after 10 attempts to start negotiations. The most
reasonable conclusion is that the ISP is no longer connected by the
time pppd starts sending the LCP negotiation messages. This is usually
because the ISP is not getting what it needs from the chat script, or is
getting something that causes it to disconnect shortly after connecting.
It also may be possible that something else is wrong and the ISP is
waiting for something from you to get started. Are you sure that the ISP
uses PAP rather than a login/password? Again - did you try CONNECT '\c' ?
Two other things you might try instead of CONNECT '' are CONNECT '\d' and
CONNECT '\d\c'.
Come to think of it you haven't posted any chat messages, are you sure
the modem is dialing out? Or dialing the correct number?
Here is a chat script that I've used to connect to my ISP that is similar
to yours.
exec /usr/sbin/chat -v \
TIMEOUT 3 \
ABORT BUSY \
ABORT 'NO ANSWER' \
'' ATZ \
'OK-+++\c-OK' ATH0 \
TIMEOUT 30 \
OK ATDT$TELEPHONE \
CONNECT '\c'
The ATZ resets the modem to a user configured profile. You could also
try replacing ATZ with 'AT&F&C1&D2', which most modems should accept.

UBR offers *no QoS*. ABR also gives a guarantee
concerning cell loss probablity (which does not mean
that it cannot occur).

CBR _guarantees_ PCR and CDVT. ABR _requires_
PCR, MCR and CDVT as attributes for the traffic
contract, but (obviously) doesn't guarantee PCR.
Also, congestion is (and therefore cell delay and loss)
an issue to have in mind when using ABR.
Hope that helps,

I am having a problem with IP aliasing on my external NIC card. It appears
to work on my internal network just fine, but I am unable to reach the
Aliased interface from the outside world. It seems that it can function
properly as I did some sniffing of my external link up to router and am
seeing the proper ARP traffic being passed back and forth.
I have my box locked down using IPFWADM and have even tried to disable it
but still had the same results.
Any help would be greatly appreciated.

Sendmail is not a pop3/imap4 server. It just delivers email to mailboxes
and exchanges email with the rest of the world.
You need another program to access the mailboxes via pop3/imap4.

Subject: Problem with RH5.2 and ISDN
Date: Mon, 08 Feb 1999 21:11:01 -0500
I need assistance/direction on setting up a Red Hat 5.2 server behind a
ISDN router (Ascend Pipeline 25).
My goal is to have the RH5.2 box acting as a firewall, DHCP server,
local DNS server, print server, home web server, email server and SAMBA
server on a 4 computer network in my home. Because I get billed on a per
call basis after my first 200 calls, I want to limit unnecessary
connections. Below find what I successfully completed and my specific
problem.
Problem
After setting up my Linux server I was shocked with a hefty
telephone bill. I get 200 free local calls and $.08 per call after that
from Ameritech (local telephone company). My ISP (ameritech.net) allows
me approx. 80 hours per month of connect time with the "Unlimited" plan,
so I can not have a permanent connection. The Linux server configured
with the services below (DHCP & SAMBA), the network established a
connect approximately every 15 minutes. I didn't notice for the first 3
weeks. This cost me big time! Now I must keep the Linux server turned
off until I solve this problem. I only turn it on to set DHCP resources
once a week.
Current RH5.2 setup
Hardware
Intel P-90 (Tyan motherboard)
NEC 4x4 CD-ROM Changer
Intel EtherExpress 10Base-T NIC
Generic Trident video card
Logitech serial mouse
Software
DHCP server
SAMBA server/client
Other hardware on the network:
(2) Intel P-120 (Tyan motherboards)
Intel EtherExpress PRO 10/100Base-T
Windows 98 PCs
NetGear 10/100Base-T 8 port hub
NetGear 10Base-T 4 port hub
Ascend Pipeline 25 ISDN router
I'm hoping someone can suggest configuration changes to enable continues
operation of the Linux box without unnecessary ISP connections.

run "netstat -nr" to avoid DNS lookups.

add default route to routes served by ppp0

Actually, the way to restrict su access is to change the value for
"SU_WHEEL_ONLY" to yes in /etc/login.defs and include all users to
be allowed to su to root in the group 0 (root).

Configure your router to start connections only
