When backing up configurations or doing filetransfers, the transfer is usually started from the node towards NetYCE.

Commands are send to the devices to do those kind of executions.

Because of the initiation on the node, the node needs to be able to reach the NetYCE instance. In some circumstances the NetYCE instance is NAT-ted, therefore known to the node with a different IP address.

Thus the NetYCE application needs to be configured to use this specific IP adress.

Shown in the example above, the netYCE VM resides inside a Laptop/Desktop/server The IP address of the VM is and Host (Desktop/Laptop IP/server) IP is

Thus the setup of NetYCE on login is as below

Starting net_setup
  Good, root privileges apply
