Overview of interactions between the laptops and their servers

The following is a high level view of how and where the XO and XS talk to each other.

Service Laptop Server Protocol Notes
School Identity Manager sugar: src/hardware/schoolserver.py idmgr: idmgr/server.py XMLRPC, port 8080 Server expects serial number, nickname, uuid, SSH pubkey; replies with success, backupurl, backuppath, jabberserver.
Ds-backup users/martin/ds-backup: client/* users/martin/ds-backup: server/* HTTP query, followed by rsync over ssh. Client and server are in the same repository.
