I need to put together a linux based Secure NTP master time server for routers, servers, and phones to get their time from, which needs to authenticate against a master time server on the internet. Nothing fancy, but it needs to be able to support authentication from routers and servers. A simple howto would be nice, thanks.
Not a real howto, but maybe this might give you some hints... http://support.ntp.org/bin/view/Support/ConfiguringAutokey
