Occasionally I am presented with keyboards that contain keys that are not recognized by default in Linux. In most cases the fix consist in select a different keyboard layout, modern Linux distributions cover a wide variety of keyboards, but some times there is no keyboard layout available that matches our keyboard and the functionality of some keys is lost. In this post I write about how to detect and map unrecognized keys. I am making the assumption that you are working in a graphical environment and that you want to give it some functionality to the key there.
If the host computer is not running SSH (or RSH), we can configure and
rsync as a daemon in this computer. This would have
listening to the port 873 for incoming connections from other computers
rsync. While this is not recommended for the
transfer of files across unsecured networks, such as the Internet,
because the actual data transfer is not encrypted, we can use this to
keep information synchronized between different computers in internal
networks, as well as perform backups.
