CHARON-AXP for Linux virtual network

General description

It is strongly recommended to use only physical network adapters for CHARON-AXP networking to gain maximum performance. In situations where the host has only one network adapter, you can use the LINUX virtual network Interfaces ("TUN/TAP") and map individual CHARON-AXP instances to their own virtual interfaces.

There are 2 ways to create the Linux virtual network Interfaces ("TUN/TAP"):

Using "ncu" utility
Manually

Using "ncu" utility to establish CHARON virtual network

Login as root. Start "ncu" utility:

# ncu

Interfaces Dedicated to State
---------- ------------ ------------
eth0       host         connected to host
eth1       host         connected to host
lo         host         unmanaged from host

==================================================================
bridge name bridge id STP enabled interfaces

select action:
1 - Dedicate to CHARON
2 - Release to host
3 - Create Bridge with TAPs
4 - Destroy Bridge
5 - Print status
6 - Exit
:> 3

Enter "3" to create a bridge between the host physical network adapter and the Linux virtual network interfaces (TAP) and specify the physical network interface ("eth1" in our example) and the number of virtual network interfaces to be created (2 in our example):

Specify the interface to be used for BRIDGE:eth1
How many tap should be created:2
Forming the bridge: ..1..2..3..4..5.. addif tap0 .. addif tap1 ..7..8 done!
Formed bridge br0_eth1 attached over eth1...

select action:
1 - Dedicate to CHARON
2 - Release to host
3 - Create Bridge with TAPs
4 - Remove Bridge
5 - Print status
6 - Exit
:> 5

Now enter "5" to see the created virtual interfaces:
