Zeroshell Livecd - providing main network services

http://www.zeroshell.net/eng/ is an interesting bundle of linux designed to be an out of the box network service swiss army knife of sorts. Here are the network services that it provides.... Kerberos 5 authentication, LDAP, NIS, Radius authentication, x509 certificate authority, unix and windows compatible active directory services, router, implements bridging and vlan protocols, full radius server, captive portal capability, firewall, QoS management, multizone dns server, dhcp server (capable of managing multiple subnets), ntp server, dyndns client, ppoe client, syslog server, lan to lan vpn.....

It IS an ambitious list, the distribution can be downloaded as an iso cd image (bootable). Personally , I hesitate a bit at the thought of having a permiter device (firewall/router) also handle authentication/ntp style services... but the fact that it runs from a livecd might give some advantages (and some disadvantages.) It is all web-browser configurable.

There's also a compactflash image downloadable for use in embedded devices.
