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.

Everybody can edit any page, this is scary. Doesn't that lead to chaos?
NTP is one of many WikiWikiClones
, the first one was built by Ward Cunningham. Collaborating the Wiki way is different from other collaboration tools like Usenet. A distinct Wiki culture
forms around these tools:
- Any and all information can be deleted by anyone. Wiki pages represent nothing but discussion and consensus because it's much easier to delete flames, spam and trivia than to indulge them. What remains is naturally meaningful.
- Anyone can play. This sounds like a recipe for low signal - surely wiki gets hit by the unwashed masses as often as any other site. But to make any sort of impact on wiki you need to be able to generate content. So anyone can play, but only good players have any desire to keep playing.
- Wiki is not WYSIWYG. Contra the dumbing down of programming, it's an intelligence test of sorts to be able to edit a wiki page. It's not rocket science, but it doesn't appeal to the TV-watchers. If it doesn't appeal, they don't participate, which leaves those of us who read and write to get on with rational discourse.
- Wiki is far from real time. Folk have time to think, often days or weeks, before they follow up some wiki page. So what people write is well-considered.
