== CMC APIs, Access Control Policy ==

This is the only service using the old API (i.e. gridservices running on port 5012 as opposed to 5022).

== Initial CMC Config File ==

The cmc config file is /etc/gridservices/cmc.yaml. The Orbit administrator creates this file. Once created, only the 'node_alias' and the 'inactive_list' fields are dynamically updated by the CMC. At creation, the administrator can set a list of nodes to INACTIVE by specifying the node coordinates in the 'inactive_list' of the testbed.

== Config File Updates ==

On startup, CMC will dynamically update the 'node_alias' field of this config file based on the existing interfaces specified in the inventory database. If there are no nodes for an interface, then "NONE" is specified for that interface.

{{{
node_alias:
    - "Atheros 802.11a/b/g:  [[13,14], [20,20], [1,17], [17,11], [11,6]]"
    - "Intel 802.11a/b/g: NONE"
    - "Belkin Bluetooth USB: NONE"
    - "Crossbow Telos Rev.B MOTE: NONE"
    - "GNURadio USRP: NONE"
    - "Marvell 88E8001 Gigabit Ethernet Controller: NONE"
    - "Intel Corporation 82540EM Gigabit Ethernet Controller: NONE"
    - "Intel 802.11a/b/g:  [[11,1], [20,4], [15,15], [20,18], [20,8]]"
}}}

The 'inactive_list' field will be dynamically updated for whenever the user sets a node to ACTIVE/INACTIVE. When a node (that is currently ACTIVE) is set to INACTIVE, the node coordinates are added to this field. Again when a node that is currently INACTIVE is set to ACTIVE, the coordinates for that node are removed from the 'inactive_list'.

=== Example ===
{{{
A) inactive_list: "[]"

B) wget -O - "http://cmc:5012/cmc/nodeSetNodeInactive?domain=grid.orbit-lab.org&nodes=[1,1..2]"
   inactive_list: "[[1,1], [1,2]]"

C) wget -O - "http://cmc:5012/cmc/nodeSetNodeActive?domain=grid.orbit-lab.org&nodes=[1,1..2]"
   inactive_list: "[]"
