Linux bridging questions

Post by Dann Farquha » Fri, 06 Mar 1998 04:00:00



I am trying to get one linux machine to bridge two thinnet segments, and also be
available for DNS, mail, webserver, etc.

I have three ethernet cards (2 3c506b's and one NE2000 PCI Clone)
3c509b  eth0  irq 11  io 0x280
3c509b  eth1  irq 10  io 0x300
ne2000  eth2  irq 12  io 0x6400

I then run the following script:

/sbin/ifconfig eth0 promisc
/sbin/ifconfig eth1 promisc
/usr/src/BRCFG/brcfg -ena

There are no error messages, when i check the cards the PROMISC flag is set.

I am assuming that the brcfg uses eth0 and eth1, but the message that prints out
only shows the hardware address of eth2

Thanks for the help

You'll need kernel-2.1.59 or up, to do so. I wasn't able to reach
the bridge from outside with 2.0.3x.

: /sbin/ifconfig eth0 promisc
: /sbin/ifconfig eth1 promisc
: /usr/src/BRCFG/brcfg -ena

How do you do this? ifconfig? If so, you have to type in ifconfig <devicename>.
The <devicename> is essential (check out ifconfig(8)).

1. Bridge: Linux as a bridge

Hi

I want to separete a Novell network running IPX in two parts.

The is no IPX connection betven the two nets, but there is some
machines that have TCP/IP, and that is what I need to bridge (not
route)

Is there someone who can help me?

I have found a small How-To, but I just don't understand excact what I
have to do?

What I think i need is a machine running Linux, 2 ethernetcards (I
will use 3Com)

But what about the software to use for the bridge.

A last questian: Can i put 3 ethernet cards in the machine, so that I
get 3 segments and not two?

I hope someone can help?
