SSH Access To Nodes

This guide will detail the steps to access the CAPC nodes.

Please note that this will only work on Isolated Networks. To access Nodes on shared networks, please configure the routes on the external network’s management plane


The user must either know the password of the node or have the respective SSH private key matching the public key in the authorized_keys file in the node

To see how to pass a key pair to the node, checkout the keypair configuration

Configure Network Access

In order to access the nodes, the following changes need to be made in Apache CloudStack

  1. Select the Public IP belonging to the network via which users can access the VM. Either use the exiting IP or acquire a new IP.
