Subject: Win98 & Linux dont see eath other
Date: Sat, 20 Mar 1999 09:45:20 -0800
Can Some one recommend a good information source for me?
My Goal is to create a client server network with my Linux and Windows-98
boxes. I have an Oracle database on Linux and I want to set up a client
session orginiating from the Win98 machine.
Steps Completed:
1. Installed 3com 3c509 ethernet cards on both machines and both machines
recognize the new hardware and have installed tcp/ip communication protocals
on both machines. (verified by pinging locally)
2. Connected to a 5 port ethernet hub via rj45 networking cables and the hub
indicates via an idiot light that a connection is happening at the hub.
3. Defined unique ip addresses, unique domain names, unique host names, and
the linux selected the netmask, default gateway and a primary names server.
Problems:
1. Everytime I want to ping from win98 the dial-up networking wants to
assume control and initiate a dialup session, therefore bypassing the local
intranet.
Question:
1. How do I get win98 to look into the intranet for the linux host.domain.
2. Is there a trick to get the linux machine to notice the win98 on the
intranet.
-Thanks

Hi!
Does anyone out there know if it is possible to just setup your own
subdomain for a legal @home address?
I have a linux firewall with two ethernet cards and connected vie
cablemodem to the real world as
xxx.yyy.home.com
Behind the firewall are some machines sitting on 10.0.0.x, using the
firewall machine as a caching nameserver (bind 8.x) and (currently) a
nameserver for a completely bogus domain (not telling outside world).
Is it possible to set up the machines on the internal network as
mymachines.xxx.yyy.home.com
by correctly configuring the nameserver and telling the real world? Would
I NEED to talk to the ISP?

Why not just just have the linux box connect to your ISP and setup IP
Masquarading (this will allow you to just set your default gateway on your
Win95 box to the IP address of the linux box).
Here is a great place to start:

They dont need a MAC address because the computer/box you are dialing uses its.
MAC address's are useful only on the local network. A host builds up a
collection of MAC address=ip address pairs so it knows who to send packets to.
This only works for the local subnet. Your computer never needs to send its mac
address of its network. If someone wants to send you a packet from outside of
your network, they will check the ip , find its not on the local net and then
forward it to the default gateway. The gateway then examines it and forwards it
based on routing information. Even the gate way only knows the MAC address's of
the localnets it borders on. When it finally get to the incoming gateway on
your network , your gateway examines its ARP tables to find the appropriate
MAC/IP address pair.
This is done by issuing a WHOHAS request on the broadcast of the network. Try
running tcpdump and watching the whohas traffic. Your gateway machine, if the
MAC/IP pair is not in cache will issue a request to the local network with
something like "WHOHAS 192.168.1.1 TELL <MAC ADDRESS OF LOCAL MACHINE>" to
which the appropriate machine will respond with an answer "I HAVE 192.168.1.1
MY MAC IS xx:xx:xx:xx:xx:xx". From then on all packets destined for
192.168.1.1 will be transferred to that MAC address.
This leads to ARP spoofong by issuing a broadcast I HAVE 192.168.1.1 without
being asked and keep issuing it frequently enough so that no host asks for it,
because it never expires in their cache.
Anyways, the point is, your MAC address should never leave your network because
it is not needed.
Routing to and from subnets is done at a higher level then MAC address's until
such time as it reaches the local subnet. type 'arp' on a unix box and check
out the tables. Only local subnet addresses will be visible.
Your modem does not need a MAC address and it would be superflous for it to
have one. When the local subnet is asked "WHOHAS <your dialup ip>" the box you
are connected to respnds with its MAC address. It recieves all packets for you
and since it knows where you live it can forward them out the appropriate
device be it PPP, MPPP or something else.
So technically you dont need every NIC to have a unique MAC address, just
enough addresses so that the probability of two cards with the same MAC address
appearing on the same network are vastly improbable.
I hope this helps (actually i hope its right too)

Just have mail sent directly to your home server.
Sendmail and pop are pretty much set up out of
the box in Redhat to do this.

Just make sure the pop entries in teh /etc/inetd.conf
file is uncommented and then just point your windows
mail readers to the address of your mail machine.
I don't use ISP mail servers so I can't comment on the
fetchmial stuff.

Is there any problem using IP Masq in conjunction with ipfwadm?
As far as the filtering, I might consider allowing arbitrary incoming
SMTP packets. Say the MX record shows xxx.xxx.xxx.y and the firewall is
xxx.xxx.xxx.z. Can I alias the 'z' to respond to 'y' and then route the
packets inside?

I used a dyn.ml.org address for a year, until Monolith went out of business.
I never heard any complaints about it.
Now that I run my own DNS (on two static IP numbers) I've considered
adding a dynamic third-level zone to one of my second-level
domains. It would be a convenience for me and my friends.
I've just never got around to it.
It's not going to "ruin" anyone's cache to have one zone in there that
lives for ten minutes, that gets perhaps five hits in a day. The
dialup system pulls mail by UUCP-over-IP. Its MX is static, and the
zone lasts 24 hours. A dynamic MX would clearly be abusive because it
would be getting a hundred hits or more daily, from many different places.
It would be even ruder to run a public Web site that way.
Most people have Web space (for a PGP key or whatever) with their ISP
or a Geocities type thing, so there's no need to run Web service from
a dyn address.
Spam is abusive because it exploits a security hole (email has no postage
mechanism and no sender authentication) to abuse the public trust.
Where's the similar abuse in non-MX, non-HTTP DDNS?

initrd image is the image of the "Initial RAM disk" which contains
some of the kernel modules that are necessary to boot up the system,

As you stated in your past messages, you have built the modules _INTO_
the kernel image, i.e. bzImage.
If you _do_ want to build them as loadable modules instead, you can do:
make xconfig <OR> make config <Whatever you want>
Select the drivers: NE2000 and 3C59x as modules [M] (instead of [Y])
make modules
make modules_install
However, please refer to my last message. In it, you can find a way
to force the kernel to detect your NE2000.
