ZeroShell 1.0.beta6 release is available at the URL http://www.zeroshell.net/eng/download/. The main new features are related to the Captive Portal which is now able to authenticate also by using external RADIUS servers and the X.509 certificates. The X.509 authentication allow you to use the Smart Card to access to the LAN.
This release includes the Daemon Watcher that is a process which checks if the services (LDAP, DNS, Kerberos, RADIUS, DHCP, ssh) work fine and it restarts them if a crash occurs.
FreeRadius is updated with the latest release which should work with the supplicant 802.1x/PEAP of Windows Vista.
