Under Buddy Update, you can specify your thin client as an update server for other IGEL thin clients. If you use a thin client as an update server, only the FTP protocol can be used to update the firmware. A number of thin clients can be set up as buddy update servers within the network.
Thin clients without a specified update server search for available servers during the update. The first update server contacted then provides the update.
