Introduction

Rutgers University's OWL (Open Wireless Lab) at WINLAB has 10 running bare metal servers.

Rescouce allocation

Inventory Table

Each machine has 3 subnets: CONTROL, DATA1, DATA2.

Services across should use DATA1, DATA2. E.g. OpenStack is on DATA1

CONTROL is use for access and the COSMOS team.

How to access a VM using SSH tunneling?

Once you have access and uploaded your private keys, you may want to access a dedicated VM for your service.

In the following example, the IP of a running SDN-R is used to view the Web UI on your localhost. Please replace '<username>' with the the username of your orbit-lab.org account.

ssh -A -t <username>@console.sb10.orbit-lab.org -L 31202:localhost:31202 \
ssh -A -t native@exper-control-1 -L 31202:localhost:31202 \
ssh -A -t ubuntu@10.31.3.21 -L 31202:localhost:31202

Public SSH-Key test:

Once the following command can be successfully executed and the <username> is part of the OSC group the <username> can access the OSC resources.

ssh -vvv <username>@gw.orbit-lab.org
