adding more PCI network cards
« on: August 03, 2014, 03:01:29 pm »
Hi folks

I have been at this  for number weeks try to adding more then one network card.

My idea behind it is to remove my four port switch down stairs from the network and plug directly into the linuxmce.

what I am trying to archive is the below.

eth1--internet
eth2 --- linuxmce network
eth3  (new net pci card) ----linuxmce network
eth4  ( new net pci card) ----linuxmce network

2 directly to my client in the TV room
3 directly to my client in the Kitchen
4 directly to my netgear wireless switch upstairs in the cinema room and to the rest the rooms upstairs.

Is possible to have more then one PCI network card working with linxumce

Please, any advice or help would be great.

Thanks Gov

Govo,

This isn't likely to work out the way you want.  Multiple adapters on the same subnet will cause you some real issues with routing, and your network will have some real stability issues.  You generally want one adapter per segment. 

The exception is usually when you need failover (bonding) or link aggregation for increased bandwidth.  There is also the possibility of using a bridged interface across multiple adapters, but LMCE's automation won't handle that, and you're more likely to tear your hair out trying to do it.  BTW, adapter numbering usually starts with 0 in *nix.  (eth0, eth1 for 1st and second adapter).

You may want to pursue a core/edge network switch layout to save yourself a lot of punishment.   Hook your best switch to the internal network adapter on the core, and connect the TV Room and Kitchen to it.  Connect your other switch to the last port on the first switch, and connect other rooms devices to it.

Hope that helps!

/Mike

you could always 'bridge' your 3 LMCE nics

Look at package bridge-utils and read this: http://www.cyberciti.biz/faq/debian-network-interfaces-bridge-eth0-eth1-eth2/
