GreenTouch VM

Network

  • eth0: NAT DHCP from VirtualBox host (to have a internet connection)
  • eth1: Bridged to host interface connected to testbed (static: 10.10.10.210/24)

Access Points

Wi-Fi

  • SSID: BCG2Demo
  • PSK: gr33ntouch

hostapd config

/ets/hostapd/hostapd.conf

# Station MAC address -based authentication
# Please note that this kind of access control requires a driver that uses
# hostapd to take care of management frame processing and as such, this can be
# used with driver=hostap or driver=nl80211, but not with driver=madwifi.
# 0 = accept unless in deny list
# 1 = deny unless in accept list
# 2 = use external RADIUS server (accept/deny lists are searched first)

# Accept/deny lists are read from separate files (containing list of
# MAC addresses, one per line). Use absolute path name to make sure that the
# files can be read on SIGHUP configuration reloads.

Public SSH Key

Our controller needs a SSH connection to each AP to obtain traffic data from it. For this, the following key has to be added into .ssh/autorized_keysfile on each AP. The controller VM is configured (.ssh/config) to have SSH shortcuts green01- green03to connect to the APs.

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC9avqGL22oIccihw5ikQOIU6q5WG/loBvQbc5ziMzoYWgXbLK9NIuLXU/C1RtnHn7vfkUy+4lV9Kq08s3FPrHxPic10PnyUrO+YMs0whn4ZqD4Og6x9alnuxwd9GApee0gNdWZ5SeBL721x6cpdj3QOOM+/3fREzf7wHjZsv0Cpg6DXqRYsEcgjTqkqF1ubgggH67CtlnVo/sBX6tkdJm8rqWbQ01DisMLSTE2Bk9MmPWCyEgj3psYSzE8tmMAKzOcDsSTZho/tzjx8HgrwHrEW55a2GFhUbyQv9jeiPSswFPIC4jakl1/Lg6zQqHkPcrTln8+jteUfcqlFx4hgPTt greentouch@greentouch-VirtualBox

Test UPB access point Manager with new access point setup

The following steps describe how to test if the new access points work together with UPB's access point manger.

  • cd Desktop/BCG_DEMO/mt_backend/ap_manager
  • python upb_apmanager.py -v -l debug -a start -c config_infocom.json

Start a second terminal and check the REST API of the access point manager:

  • curl 127.0.0.1:6682/api/network/accesspoint

  • Response: {"offline": [], "online": ["e60db822c51d330bbf6954f306941678", "c3b4a156913a37bf8e11e0bf756fcd9f", "dd8a05d9212131dcbb531ffc5cdd3979"]}

  • curl 127.0.0.1:6682/api/network/accesspoint/e60db822c51d330bbf6954f306941678/info

  • Response: {"state": "online", "uuid": "e60db822c51d330bbf6954f306941678", "serial": "00156195a7c1", "name": "green01"}

  • curl 127.0.0.1:6682/api/network/accesspoint/e60db822c51d330bbf6954f306941678/stats

  • Response: {"aps": [{"txbyte": 748644, "name": "wlan0", "rxbyte": 353270, "timestamp": 1457093744.035127, "txpkt": 0, "rxpkt": 0}]}

  • TODO: This one might be critical because it parses ifconfig output after executing the command via SSH on the access point. A different ifconfig versions might cause trouble here. This is why we have to check this before Infocom.
