8 # This wrapper implements the Geni Registry and Slice Interfaces on PLC.
9 # Depending on command line options, it starts some combination of a
10 # Registry, an Aggregate Manager, and a Slice Manager.
12 # There are several items that need to be done before starting the wrapper
15 # NOTE: Many configuration settings, including the PLC maintenance account
16 # credentials, URI of the PLCAPI, and PLC DB URI and admin credentials are initialized
17 # from your MyPLC configuration (/etc/planetlab/plc_config*). Please make sure this information
18 # is up to date and accurate.
20 # 1) Import the existing planetlab database, creating the
21 # appropriate geni records. This is done by running the "sfa-import-plc.py" tool.
23 # 2) Create a "trusted_roots" directory and place the certificate of the root
24 # authority in that directory. Given the defaults in sfa-import-plc.py, this
25 # certificate would be named "planetlab.gid". For example,
27 # mkdir trusted_roots; cp authorities/planetlab.gid trusted_roots/
29 # TODO: Can all three servers use the same "registry" certificate?
32 # TCP ports for the three servers
