Your hosts.allow line looks alright to me (after a quick RTFM). What did you put in
hosts.lpd? My print server is running
Caldera 1.2. The client I'm typing this from runs Redhat 5.1. With a standard BSD
lpd an lpd.hosts with a single line with "+"
would be both necessary and sufficient ( I say this after spending the better part of
a day earlier this week configuring a BSD
lpd to run under solaris 2.6 - compiling under GCC vs Sun workshop compilers solved
most of that problem). I looked at my
caldera print server and found NO hosts.lpd file whatsoever. This leads me to believe
I am NOT running a BSD derived lpd.
(Excuse me while I look at www.caldera.com and www.redhat.com)
I'm back now.
www.caldera.com tells me I'm running LPRng (that's funny, I still have most of my
hair). "man lpr" mentions LPRng. Pretty good
confirmation.
I can't find any mention on www.redhat.com but a "man lpr" on my redhat machine
returns something that looks a WHOLE LOT like a
standard BSD man page.
Conclusion: I believe you are running a standard BSD lpd and I am not. This leads me
to believe that a hosts.lpd that looks
like:
+
should be enough to get you by. I don't think hosts.allow or hosts.deny will be
consulted by your BSD lpd and are therefore
irrelevant to the current discussion.
Give it a try. Let me know whether it works or not. I'm always trying to learn.

Do you have assigned 'static' addresses...? from your provider. I'm
not
sure about Shaw, but many CMP's use the 'computer name' / hostname
to login the DNS, and assign the address(s). Thus, Mr. Linux box
will
need to run DHCP 'dhcpcd'

Try configuring the DHCP client on the Linux box, look for it here:
ftp://sunsite.unc.edu/pub/Linux/system/network/daemons/
and download the dhcpcd-0.70.tar.gz program. Installing it is
pretty streight forward.

No, The Linux box will assign itself the correct gateway when it
connects to your CMP. (this is somewhat of a guss, because as I
said, I'm not sure about Shaw, and I seen nothin in the
Howto..)?
Normally, the system looks for it's assigned gateway on the LAN,
then the gateway, i.e. a system with 2 ethernets sends packets
to/from the Internet.
>However, anything outside my two machines are invisible to my

>and I am unsure if I can get Linux to do that .
Yes, Linux will do this happly. DHCP is simple to install. I
think once the Linux
box is running DHCP, it will connect.
Some pointers:
If Shaw is anything like @home, you'll need another IP
address/hostname, if
you don't already have two (one for the winblows, and one
for the Linux box)
I don't think you can log in with two hostnames the same..?
An alternative would be IP_masquerading, this way you keep
the LAN intact,
and use the Linux machine as the gateway for the winblow(s)
machines.
The Linux machine will need 2 ethernets to do this.
I only seen one win box in your diagram, (running IP
masquerading might still be
a better idea, and save you a little on a second IP...?
@home removes your 'assigned IP address(s), the ones you set
on the win boxes,
and disables file and print sharring (:>( , so you loose the
LAN. They DO NOT turn
on the DHCP stuff on the win machines because the computer
name / hostname is
used to log, and assign the static address(s).

I think the CMP (Shaw) dosn't recconize the Linux box's
hostname.
**Please forgive if any of this turn's out to be incorrect,
i.e.. with Shaw's setup, and once
you get things running, please post. There may be other 'Shaw'
users with Linux!

1) The linux box is in the sparebedroom out of the way and also does not
have a modem or a phone line to connect to.
2) I am reliant on other people to open boxes for me and swap hardware.
3) I am responisible for some daily running of websites and have my
win98 box setup (for 3 years now) to do the job, so transistion will
have to be done slowly and not interfere with my daily web work.
Thats is why I would want to do this, perhaps you should have said "What
reasons have put you in the situation where you have to do this and
would you rather have the linux box be your internet gateway?"
:-)
Rather academic since installing MSIE5 Beta2 I have been unable to get
OMNI's web server to run on the win98 box, even after uninstalling it
the win98 box will not let it start. Apache V1.3.3 win32 does, however
work complaining about the host name worsdall.demon.co.uk not being able
to be resolved. STILL THIS IS NOT RELEVENT in this group.

some port redirection. The problem is how do I get pppd to open a

However, the site where the src is located , www.tunes.org, is not

If you have enough drive space, and if you run fat16 then xcopy the redhat
directory and rawrite as well as the 2 boot images from the cd to your
win95 drive. Use fips to free up and create a free partition if you dont
already have one. The create the boot disks using rawrite and the images
you copied from the cd. Boot with the linux diskettes and choose "install
from hard drive" when prompted by menu's. Point the
source to /redhat on the dos drive and it will do the installation.

Subject: EQL/MultilinkPPP; ~100kbps=2 x 56k modems?
Date: Sun, 3 Jan 1999 00:30:37 -0800
As I promised that I was going to post the result of
my struggle with EQL and Multilink PPP, I am posting what I have
found so far.
My goal:
I have a small network of four computers at home. I wanted to
connect these computers to the Internet as fast as possible,
and as cheap as possible. I looked for a way to bond two phone
lines as one to get a fast connection, i.e., two 56k modems = ~100k.
I tried EQL and Multilink PPP on Linux to have a Linux box to
work as a router. But I ended up using WinProxy on Windows98 to have
it work as a router. Because I found the following facts:
About EQL:
You need a static IP address for your Linux computer at home.
However, most ISPs will assign you an IP address dynamically.
ISP needs to have a router, Livingstone Portmaster 2 or later.
I could not find any ISP using this type of router in my area.
About Multilink PPP:
Linux support for Multilink PPP has been on the wish list
of kernel development for a while, but it is still at its
early stage. (Very limited Multilink PPP is possible with
kernel versions 2.1.37 to 2.1.43, which are outdated.)
About WinProxy:
I got an account from an ISP with Multilink PPP support.
My account costs $29.95/mo. with unlimited usage and five e-mail accounts.
(Let me know if you would like to know which ISP I am using.)
Just set up Multilink as instructed on Windows98.
Setup WinProxy just as instructed on its User's Manual.
You are done. You get ~100kbps connection to the Internet from Windows and
Linux computers on the network at home. (Oh, yes, you can use cheap winmodems.)
It should also be possible to get ~150kbps connection if you have three
phone lines and three 56k modems (if your account allows three connections).
But I haven't tried because I have only two phone lines.
I really wish Multilink PPP support in Linux is going to be available soon..

Thanks for your help.
I'm trying to run two simple programs, cook.c and chef.c.
When runnig as root - it's fine.
When running as a simple user it stack at cook.c on the connect function
call.
I did change permissions , ownership and group, and copied the files to a
user's writeable library.
socket and all other functions returned a correct return code, but still
- connect never ends.
The programs are attached.
Thanks,
Moshe.

Why do you think that you need two? An single DNS server can be both
authorative for some domains and act as a recursive server for others.

Why? Surely this would be the simplest solution.

That is right.

You will have to be more precise about what it is you wish to avoid
doing. It's as though you say "I want to knock in a nail but I don;t
want to use a hammer". I could say "knock it in with a rock" but in
that case the rock would be acting as a hammer - so you would still be
using a hammer.
A stub zone may be a solution to your problem but until you explain
your problem I can't be sure.
> Do i have to use named and how i configure it ?
Yes, to run any nameserver you need named.

Not clear what you mean. A client can connect to an AF_UNIX socket
if it has filesystem permission to the socket, since AF_UNIX sockets
exist on the filesystem as special files. And any user process can
create an AF_UNIX (Unix Domain) Socket if they have rights to
create in the directory where they are trying to put the socket.
What are you trying to do?

Subject: SNA for Linux??

Where can I get info on implementing an SNA server on Linux?
I would like to replace a old and about-to-die Novell machine with a
Linux box.
Has anyone tried this successfully? An good documentations?
Thx

I just tried this on my system using TCP wrappers.
I originally had a line in my /etc/hosts.allow:
ALL : localhost
which allows access to all services by users on my system. I commented this
out, and inserted a new line:
ALL : stu@ALL
Now, from a root account, I tried to telnet to localhost and was refused
before ever receiving a login: prompt. Then, from my "stu" account, I was
able to login successfully. I believe that you would be able to extend this
exercise to allow "joe" to login from anywhere.
