olpc-netstatus # Collects/Displays useful data regarding the Network configuration. # It determines whether the XO is connected to # Simple Mesh, School Mesh, Simple Wifi, School Wifi, or MPP. # It requires sugar-telepathies and sugar-xos # to get the number of XOs seen in the mesh view, # and to list the active Telepathies with their status. $olpc-netstatus Model : C2 Serial : CSN74400049 MAC : 00:17:C4:0C:CD:11 Build : update.1 703 Firmware : CL1 Q2D14 Q2D Libertas : 5.110.22.p1 Nick : W03 Uptime : 01:12:06 IP eth0 : 172.18.0.250 IP msh0 : 169.254.5.77 DNS : 172.18.0.1 Telepathy : gabble Jabber : schoolserver.laptop.org XOs : 4 Essid : zoom50 Channel : 11 School : schoolserver.laptop.org Config : School Wifi
olpc-log # It collects all useful logs, files, command outputs # and saves them in a S/N defined and timestamped tarball # It gets the output of almost all scripts in the olpc-utils package # For a list of collected logs try # olpc-log --help
olpc-connections # Tracks all changes in msh0 and eth0 IP, # resolv.conf, Telepathy status, Jabber connection and number of XOs in mesh view. # It can give a readable view of how the network behaves over a period of time. # It uses sugar-telepathies and sugar-xos $olpc-connections | msh0 | eth0 | dns |salut|gabbl| jabber | xos 22:32:30 | 172.18.10.214 | | 172.18.0.1 | on | | | 20 22:41:53 | 172.18.10.214 | | 172.18.0.1 | on | | | 1 22:42:02 | | 18.85.18.254 | 18.85.2.138 | | on | 18.85.46.29 | 3 22:42:07 | 169.254.5.77 | 18.85.18.254 | 18.85.2.138 | | on | 18.85.46.29 | 3 ...

sugar-telepathies # These are used as libraries from the other scripts sugar-xos # to display the DBus XOs, and active Telepathies
The above scripts are all included in this package
Action USB key # It is a bootable USB key that you may use to # customize your image, collect data, and have commands to run at boot. # More info in the README
Cloaked School # This script helps the XOs associate to a # School Wifi configuration equipped with a cloaked AP, and in the NYC deployment. # At boot it checks whether the AP is available, and switches between Home and School mode. # In School mode, it disables NM, and associates to the AP manually. # The XO will still be able to collaborate if a Jabber server is available.
