basic routing problem

Hello,

Great :)! Everything is working now. Thank you. But could you tell me
one more thing - in which file in debian are stored these information
(i.e. ifconfig configuration and routing traces) so that I could just
write it to the files without adding everything from the beginning
every time.

Regards, mark

Network interface configuration : /etc/network/interfaces
See 'man interfaces' and
http://www.fr.debian.org/doc/manuals...tml#s-net-high
Add custom routes : see the 'up' option.

Enable IP forwarding : /etc/network/options (deprecated soon)
or /etc/sysctl.conf (see 'man sysctl.conf')
or in an 'up' option in /etc/network/interface, but that's dirty.

VLANs ?

We use 6 or 7 subnets, all of which are connected to one switched
backbone; routing is done via Layer 3 switching.

Granted, for simple setups this is a good rule to follow.

Hello,

This time I just want to build a ring (so that the messages goes in
one-way circle)
My net:

--> (10.0.3.2) Deb01 (10.0.1.1) --> (10.0.1.2) Deb02 (10.0.2.1) -->
(10.0.2.2) Deb03 (10.0.3.1) -->

How should I set routing so that if I ping from Deb01 to Deb03 then
echo request would go Deb01->Deb02->Deb03, but echo reply would go
Deb03->Deb01??

Would be grateful for help here.

Regards, mark

Why? I honestly can't think of any reason why that would be helpful.

man route look for the metric variable. Expect a lot of chances for
things to go quite wrong. Also expect lower performance.
