Client Properties

The IRIS server has a configuration file which contains default properties for clients — /etc/iris/ These properties include internationalization, network proxy, and other system configuration. Note that even though IRIS has been internationalized, it has not yet been translated to languages other than english.

User Properties

The IRIS client also reads a property file on client computers. The file is named, and can be found in the iris folder of the user’s home directory. It can contain overrides for any of the values in the client properties file.

The file is overwritten when logging out. The window geometry and last selected tab will be updated, but all other properties will be left unchanged.
