NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

Administrative Mailing Lists

We need some new (different) mailing lists. At the moment, these new mailing lists will probably be closed/private lists

Please edit/revise/add comments.

Here's a table of folks and topics - it may help.

[Edited according to previous discussions and comments on this page.]

Note that "root" would be handled exclusively as an alias and not a list, in case of serious problems while Mailman was non-functional. We can discuss whether or not we should do the same for postmaster, webmaster, and abuse.

Also note that most of the corresponding addresses on maccarony for ntp.org are already being forwarded to their counterparts on ntp1 for ntp.isc.org. So, postmaster@ntp.org is forwarded to postmaster@ntp.isc.org, webmaster@ntp.org is forwarded to webmaster@ntp.isc.org, etc....

We must ensure that root@isc.org only sees the output of periodic jobs and root mail that Really Counts(tm).

-- SteveKostecke - 09 Nov 2004


Done. The root crontab on ntp2 now has MAILTO="reports@ntp.isc.org", which will prevent root@isc.org from receiving any of those messages.

There is no root crontab on ntp1, but we will need to keep this modification in mind should we create one.

There was no modification made to /etc/crontab on either machine.

There's also a need for a separate list for people wanting to email updates to the time server list rather than it being an alias to webmasters or whatever.

-- DannyMayer - 09 Nov 2004


Forwarding localpart@ntp.org to localpart@ntp.isc.org is no longer necessary now that we've moved to ntp.org.
