During your approved time slot, you will be able to ssh into the console of the respective domain. A console is a dedicated machine that allows access to all resources in that domain.
For example, to access the sandbox1:
yourhost>ssh username@console.sb1.orbit-lab.org Using username "username".

How to switch On/Off the nodes of a Testbed ¶
To switch some nodes On/Off on the 'grid' testbed, use the command:
omf tell -a on -t all
will turn On the entire set of 20x20 nodes on the grid.
omf tell -a offs -t node3-1.grid.orbit-lab.org,node5-6.grid.orbit-lab.org,node1-1.grid.orbit-lab.org,node1-2.grid.orbit-lab.org
will turn Off (soft, that is attempt a graceful shutdown) the nodes 3,1 and 5,6 and 1,1 and 1,2
omf tell -a offh -t node3-1.grid.orbit-lab.org,node5-6.grid.orbit-lab.org,node1-1.grid.orbit-lab.org,node1-2.grid.orbit-lab.org
will turn Off (hard, that is "hold down" the power button) the nodes 3,1 and 5,6 and 1,1 and 1,2
Learning More ¶
The complete available options for this command is given by "omf help tell":
user@console.grid:~$ omf help tell
Switch ON/OFF and reboot the nodes in a testbed
Usage:
omf tell -a ACTION [-h] [-t TOPOLOGY] [-c AGGREGATE]
With:
-h, --help print this help message
-a, --action ACTION specify an action
ACTION:
on turn node(s) ON
offs turn node(s) OFF (soft)
offh turn node(s) OFF (hard)
reboot reboots node(s) (soft)
reset resets node(s) (hard)
-c, --config AGGREGATE use testbed AGGREGATE
-t, --topology TOPOLOGY a valid topology file or description (defaults to 'system:topo:all')
Some Examples:
omf tell -a reset
omf tell -a on -t system:topo:all -c grid
omf tell -a reboot -t omf.nicta.node1
omf tell -a offs -t omf.nicta.node1,omf.nicta.node2 -c sb1
omf tell -a offh -t system:topo:all
omf tell -a reset -t topo_grid_active
Of particular interest is the -t flag which can be used to specify arbitrary topolgies. These can be of the form "nodex1-y1.fqdn,nodex2-y2.fqdn,…"
