1 This installation note assumes that you have installed and configured MyPLC in the usual manner, and you have set up your yum repo like for a MyPLC install.
3 Once you have completed the server configuration, a brief introduction to the SFA user tools is here:
4 http://svn.planet-lab.org/wiki/SFAGuide
7 1) Install the SFA packages:
9 # yum install sfa-plc sfa-client
11 Note that the above command installs both sfa server (sfa-plc) and sfa client packages along with necessary dependency packages. Depending on the requirements, you may choose to install the appropriate one (server, client or both) for you. For e.g. to set up your own SFA server on top of your MyPLC, you need sfa-plc. On the other hand, if you plan to use an existing SFA server, you would typically need the sfa-client only.
13 2) Note down the PLC_ROOT_USER, PLC_ROOT_PASSWORD, PLC_DB_USER and PLC_DB_PASSWORD of your MyPLC installation:
16 Enter command (u for usual changes, w to save, ? for help) s PLC_ROOT_USER
17 PLC_ROOT_USER = root@test.onelab.eu
18 Enter command (u for usual changes, w to save, ? for help) s PLC_ROOT_PASSWORD
19 PLC_ROOT_PASSWORD = test++
20 Enter command (u for usual changes, w to save, ? for help) s PLC_DB_USER
21 PLC_DB_USER = pgsqluser
22 Enter command (u for usual changes, w to save, ? for help) s PLC_DB_PASSWORD
23 PLC_DB_PASSWORD = 4a333aba-a322-41b1-9c05-90b4f34d1332
25 These four configuration parameters are required for SFA server configuration
27 3) Configure and start SFA servers:
31 set SFA_PLC_USER to PLC_ROOT_USER
32 set SFA_PLC_PASSWORD to PLC_ROOT_PASSWORD
33 set SFA_PLC_DB_USER to PLC_DB_USER
34 set SFA_PLC_DB_PASSWORD to PLC_DB_PASSWORD
37 *NOTE* at this point you get a warning b/c the authorities hierarchy has not been created yet; ignore
39 (b) # sfa-import-plc.py
41 (o/p will look like this)
42 Import: creating top level authorities
43 Hierarchy: creating authority: plc
45 Import: creating table for authority plc
46 NOTICE: table "sfa$plc" does not exist, skipping
47 inserting authority record for plc
48 Import: adding plc to trusted list
49 Import_Site: importing site plc.internet2
50 Hierarchy: creating authority: plc.internet2
51 inserting authority record for plc.internet2
52 Import_Site: importing site plc.pl
53 Hierarchy: creating authority: plc.pl
54 inserting authority record for plc.pl
55 Import: importing person plc.pl.root
56 Import: creating table for authority plc.pl
57 NOTICE: table "sfa$plc$pl" does not exist, skipping
59 (c) run sfa-config-tty again and select q to come out of the config command
60 This will initialize /etc/sfa/authorities/server.key from /etc/sfa/authorities/plc/plc.pkey
62 (d) # service sfa start
63 This will start Registry, Slice Manager and Aggregate Manager. Your ps command output would look like:
65 # ps -ef | grep python
66 root 24944 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -r -d
67 root 24957 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -a -d
68 root 24970 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -s -d
70 4) Configure SFA client:
73 (b)copy your private RSA key to ~/.sfi/username.pkey Replace username with your actual account name. NOTE: DSA KEYS WILL NOT WORK
74 (c) # cp /etc/sfa/sfi_config ~/.sfi/
75 (d) edit ~/.sfi/sfi_config. A sample configuration looks like:
77 export SFI_AUTH=plc.pl
78 export SFI_USER=plc.pl.root
79 export SFI_REGISTRY=http://vplc25.inria.fr:12345/
80 export SFI_SM=http://vplc25.inria.fr:12347/
82 (e) # source ~/.sfi/sfi_config
86 At this stage you should be able to run sfi command. Some sample outputs are:
88 (a) # sfi.py list plc.pl
89 plc.pl.netflow (slice)
94 (b) # sfi.py show plc.pl.pif
97 uuid: 99878316891261700702442883738232624912
101 hostname: pif.inria.fr
103 (c) # sfi.py show plc.pl.root
106 uuid: 67306954103472941609600457537601239401
109 last_name: Administrator
111 key: plc.pl.root#user
113 email: root@vplc25.inria.fr
119 (e) # sfi.py resources
120 <?xml version="1.0" ?>

124 6) Federation configuration:
126 (a) Follow the same procedure to install and configure second MyPLC with SFA server.
127 (b) On each PLC, edit the /etc/sfa/registries.xml file
129 set addr to ip or hostname of federated (remote) peer
130 set port to sfa service port on federated (remote) peer
131 set hrn to human readable name of federated (remote) peer interface
132 Sample configuration:
135 <registry addr="vplc26.inria.fr" hrn="ple" port="12345"/>
138 (c) Likewise, edit the /etc/sfa/aggregates.xml
142 <aggregate addr="vplc26.inria.fr" hrn="ple" port="12346"/>
145 (d) trade trusted root gid's (seen on /etc/sfa/trusted_roots)
146 we have to copy the gid of first SFA server to the /etc/sfa/trusted_roots directory of second one and vice-versa.
