Power cycle a node, on "boss":

 power cycle <node>

Add (or remove) a user to (from) the wheel group:

 wap unixgroups -a [user] wheel
 Usage: /usr/testbed/sbin/unixgroups <-h | -p | < <-a | -r> uid gid...> >
  -h            This message
  -p            Print group information
  -a uid gid... Add a user to one (or more) groups
  -r uid gid... Remove a user from one (or more) groups

Check the syntax of an ns file:

 nscheck nsfile
  where:
  nsfile    - Path to NS file you to wish check for parse errors

Mark nodes "hwdown", on "boss".

 (Make sure that /usr/testbed/sbin is in your path.)
 wap sched_reserve emulab-ops hwdown [list-of-nodes]
                              ^ desired state
 
 nfree emulab-ops reloading [list-of-nodes]
                  ^ current state

To allocate node(s) that are currently "free", on "boss":

 nalloc emulab-ops hwdown [list-of-nodes]
                   ^ desired state

 Usage: nalloc [-v] [-p] <pid> <eid> <node> <node> <...>
  -p enables partial allocation mode
  -v enables debugging output

Get switch statistics (such as packet counts) for an experiment. On "users":

 portstats <proj> <exp>
 prints statistics for all experimental interfaces in an experiment. 
 portstats -h
 lists the other options.

Load an image onto node(s) in an experiment.

 os_load [options] node [node ...]
 os_load [options] -e pid,eid
  where:
  -i    - Specify image name; otherwise load default image
  -p    - Specify project for finding image name (-i)
  -s    - Do *not* wait for nodes to finish reloading
  -m    - Specify internal image id (instead of -i and -p)
  -r    - Do *not* reboot nodes; do that yourself
  -e    - Reboot all nodes in an experiment
  -z 1  - Zero unused portions of the disk.
          (Currently only on "boss".)
  node  - Node(s) to reboot (pcXXX)

  Wrapper Options:
   --help      Display this help message
   --server    Set the server hostname
   --login     Set the login id (defaults to $USER)
   --debug     Turn on semi-useful debugging

Schedule a Node's future assignment(s)

 wap sched_reserve <pid> <eid> <node> [<node> ...]

Schedule a OS installation

 wap sched_reload (see sched_reload --help)

Release a node from it's current assignment.

 wap nfree <pid> <eid> [<node>] [<node>...]
 ***don't forget the node name or you'll free 
 ***all the nodes in the project/group
