setnet.sh is a simple state-less tool to manage and configure network
interfaces. It is a shell wrapper around the functionalities of
standard command-line tools, including "ip", "dhclient", "wpa_cli",
etc., and can be used to configure network connections via
Ethernet/Wi-Fi interfaces.
Both Static and DHCP-based IP configuration are supported.
At the moment, only WPA-PSK and open (no key) Wi-Fi connections are
available.
For more information, please visit the webpage of the project:
http://kalos.mine.nu/setnet/
