Battle Of The Iethernet Cards

Battle Of The Iethernet Cards

[Rejean Proulx]

I have 2 Lan cards in my Linux machine.  each card is connected to a subnet
that has a high speed modem.  Apache and Exim seems to share these 2 network
cards.  I want to tell my machine that I only want Wan or external
communications to go through one of the cards.  The other card is for local
file sharing only, at least as far as Linux is concerned.  The other high
speed modem is for the Windows machines.  How do I do this?  For now, I had
to disconnect a card, so now I can't get at Linux using Samba with half my
network.  I need to control the fact that although I have 2 modems, I only
want Linux to use one of them.

You should set a listen directive in your httpd.conf file and relitave 
directive in your exim.conf file.
for apache this should look like listen 192.168.0.1 replacing the ip 
with that of the interface you want apache to use.

RE: Battle Of The Iethernet Cards

[Joe Clever]

Since I have not seen any other replies, I will take a crack at this. I
think you are asking how to bind different apps/daemons to different
interfaces. I think that you will have to go searching for options in each
applications/daemons config/startup files/scripts. Often the app/daemon
will, by default, bind itself to all interfaces that it can identify. In
other words, you have to tell it if you want something different.

Re: Battle Of The Iethernet Cards

[Allan Shaw]

Hi Rejean,

Well my first suggestion based on other notes we've exchanged, would be to 
take a step back and truly look at what it is you want to do at the end of 
the day.
If you simply move forward at this point your just going to create a 
situation where the only way to fix the next problem will be to go back to 
the beginning and start from scratch.

However, lets see what we can do with your current configuration.

Are you or have you been using your Linux box as a gateway or Proxy Server?
If so you may have to uninstall these services or at least stop them.

Here is what I would do ...

1: Plug modem into up link port of router and put the second one in a box 
some where.
2: Be sure to assign your 2 servers static IP's if not already done.
3: Have router issue dynamic IP if possible to all other workstations 
excluding the above IP addresses using a single subnet.
4: configure router to direct various services such as (http, ftp, pop, 
smtp) to the appropriate server and IP address.
5: Make sure all services and features are all fully functional/operational 
before adding or configuring any new service.
6: KISS, make your life simple and avoid complication.

Now I'm not sure if any of the above will work with your environment but I 
know it can work and is how I've set things up on my home network.

Hope this helps.

Re: Battle Of The Iethernet Cards

[Rejean Proulx]

Thanks, this is good.  That should take care of the ability to force them to
use a specific card.  Now I need to stop it from changing IP's all the time.
Windows was friendly that way.  If the previous IP was available it would
use it.  Linux is unpredictable.  I think I'll have to go to static IP rout
on the card that is used for the internet.  I might keep my 2 subnets a
little longer. Lets see if this works.  I hope so.

Re: Battle Of The Iethernet Cards

[Luke Davis]

You should do that anyway (statics for the net boxes).
However, a MAC-spesific lease, should be as good as a static IP, if your
router can do that.

Re: Battle Of The Iethernet Cards

[Rejean Proulx]

I can only set up a lease for 1 day, which I was doing, but it occasionally
messed me up.  I need to figure out some sort of VPN that will let my other
machines access the Linux box through the modems.  I wish I could get rid of
a modem, but I can't.  Maybe I'll look at other routers but not just yet.

Re: Battle Of The Iethernet Cards

[Geoff Shang]

Hi:

Not sure if I'm clear on your setup, but wouldn't a routing table clear up
this issue?  Type the commmand:

route -n

and show us the output.

Of course, unless you really needed your machines to use different internet
connections, you could just have your linux machine connected to the net
and do IP masquerading for the other boxes.

Geoff.

That still doesn't effect regular traffic, other than mail and web.  For
example, originating outgoing traffic.

What about some sort of default route arrangement?

That's kind of what I was thinking.  It should be possible to set the
default route, to work through the cablemodem router, and set only what
ever private class C is desired, over the other card, and only that class
C.
Then, run Samba, listening only to the class C interface, and all other
services listening to all interfaces, but only originating connections on
the cable modem router interface.

There are ways to forse all of this with iptables, but I would personally
consider that a cluge.

If you run a big network, with many machines, and more than one server,
his setup actually does make some sense.  The windows segments use one
highspeed conection, with their services, and the Linux side uses its
highspeed connection, with its services.
Depending upon your available connection speeds, this can be understood as
valuable, although with a slight dubious factor.
However, knowing various things about his setup, it does make sense.

> and do IP masquerading for the other boxes.

Note: when dealing with always-on connections, it qualifies as NAT.
masquerading applies only to temporary (usually dialup) PPP connections.

Luke

Re: Battle Of The Iethernet Cards

[Luke Davis]

A form of source-NAT, or many-one NAT, for PPP, or temporary, connections.
