Debian Edu Help

Hi all.

In my school i install Debian edu. But i have a little problem, eth2 don't want work. I want to implement this scheme in school http://i33.fastpic.ru/big/2017/0504/...7b751d764.jpeg

Thank you for help
You are trying to route the same subnet to two different interfaces. There can be only one.
You will have to logically split that 10.0.0.0 subnet to send part to eth0 and the rest to eth2 to get traffic on both interfaces. Manipulating the subnet masks will accomplish this.

How to do it logically? I have a big network, and i don't know how to do this. I have nearly 270 mobile users and 10-15 notebook users who use Ubiquiti Unifi, i want to sent their traffic to eth1 (default LTSP network) and the rest 60 users (teachers and other directory) PC send to eth2. Maybe i'm wrong to do this, but i dont have idea. + i am from Ukraine and my english is not well.

Well, what I was thinking of doing depends upon the IP address. Unless the different kinds of users get different ranges of IP address that might be difficult. IF they do get different IP ranges, then manipulating the network masks on that interface to include (and ONLY include) the range required might do the job.

I may not be understanding you properly, as the PURPOSE or goal of doing this is not clear, but your translation to English is quite good.

Do you know how to change the subnet mask for the traffic on an interface?
Do you know how to add or change a network route?

You mean to change subnet mask eth2?

OK, look at the eth1 device: it has address 10.0.2.2 with mask 255.0.0.0 so it wants to route all of 10.0.0.0 to 10.255.255.255 as its local network.

Then look at eth2: it has address 10.0.3.1 with network mask 255.0.0.0 so it ALSO wants to route all of 10.0.0.0 to 10.255.255.255 as ITS local network.

Only ONE can win!

What are the REAL subnets you use within the 10.* class A subnet? We need to split them up logically to restrict the interfaces local networks to only include the parts you want to address on that interface.

might be a start. I cannot tell what subnets are in actual use, and which are fixed and which dynamic, without you providing that information. I THINK that with that information we MIGHT come up with a plan. I KNOW that without it I am flying blind over here.

I know of no provision in networking to route to a 'fake' network that is the same as a real subnet.
If I understand you, that is what you have here.
You cannot route traffic for the 10.0.0.0/8 subnet through two interfaces. It simply cannot be done.
Now there may be potential to route certain TRAFFIC (as from a subset of the internal network, or certain ports only) to a different interface, but if it is connected to the same subnet I am confused about what value would derive.

Can you clarify? What is the real objective here. As stated, this does not make sense.

From your previously posted information about the addresses of the interfaces, I can presume that you MIGHT have some devices addresses on the (most likely) class C subnet 10.0.2.0/24 and other addressed on the 10.0.3.0/24 subnets. Your default gateway is 10.0.0.1 so that is using the 10.0.0.0/24 subnet. Subnet separation is key to dealing with this routing at the address level.

Given these I know that we need to consider traffic addresses for 24 bit mask networks 10.0.0.0, 10.0.1.0, 10.0.2.0, and 10.0.3.0.

Are there other class C subnet addresses used in your network?
