Hi, As you may be aware, massive distributed denial of service attacks have been mounted over the last couple of weeks by sending forged administrative queries to public NTP servers. A favourite query in use is "monlist", which results in a constant stream of data being returned from the NTP server to the victim host. While we have no evidence that any BitFolk VPS has so far been used in such an attack, we are going to take some pre-emptive action to minimise the risk. As there is no need to allow these administrative queries from the entire Internet, we now require these to be disabled by default and only allowed from specified trusted hosts. This has always been the configuration provided to you on provisioning of your VPS, so only those who have changed their ntpd configuration would have re-enabled administrative queries. Disabling administrative queries is normally achieved by using the "noquery" option in the "restrict" lines. This setting does not disallow time synchronisation.
