All floating IP's within skyhigh is are accessible to all machines in the cloud (if permitted by the access groups). All users with an active project in skyhigh is are able to log in to "skyhigh.hig.no", and trough that machine it is possible access all other machines. This machine also allows ssh-tunnels to tunnel other traffic trough SSH (f.ex RDP, HTTP(S) and similar).
In order to access your own virtual machine through the jumphost via SSH on a Linux machine, follow the following steps:
- Establish a SSH tunnel through the jumphost "skyhigh.hig.no" by executing the following command on your terminal:
#ssh [NTNU-username]@skyhigh.hig.no
e.g: ssh danil@skyhigh.hig.no
- use your NTNU user name in order to log into the jumphost - After having logged in into skyhigh.hig.no, start an SSH connection to your virtual machine in openstack by executing the following command:
#ssh -i $HOME/.ssh/ntnu-openstack.pem ubuntu@vm-ip-address
e.g: #ssh -i /home/danil/.ssh/my-private-key.pem user@172.16.1.140
- use the private key that you generated/uploaded when creating the virtual machine through the openstack webinterface.
PPTP VPN
If you would like to have IP connectivity between your machine and machines in skyhigh directly, without using SSH tunneling, there are a PPTP VPN service available. Please contact Eigil or Lars Erik for credentials to this service.
