CHARON-VAX for Linux virtual network
Table of Contents
General description
It is strongly recommended to use only physical network adapters for Charon-VAX networking to gain maximum performances. In situations where the host has only one network adapter, you can use Linux virtual network Interfaces ("TUN/TAP") and map individual Charon-VAX instances to their own virtual interfaces. This can be done using the ncu utility.
It is also possible to perform the operations manually. Refer to your Operating System Network Administration guide for details.
On Red Hat Enterprise Linux 6 & 7 and CentOS 7, the following packages are needed:
bridge-utils- optionaltunctl- optional, need only if command 'ip tuntap' not workedethtool- mandatoryvconfig- optional, if VLAN is needed
On Red Hat Enterprise Linux 8 and CentOS 8, the following packages is needed:
ethtool- mandatory
Using "ncu" utility to establish Charon virtual network
Login a root and start the ncu utiltiy:
|
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 the virtual network Interfaces to be created (2 in our example):
|
Now enter "7" to see the created virtual interfaces:
