Re: [time-nuts] Leap-second capture on laptop

2017-01-01 Thread Philip Gladstone 
I added this message to the Linux kernel near the end of 1993. There is 
a companion message that indicates the removal of the leap second -- but 
this has never been seen (except in testing!).


In retrospect, it isn't clear that jumping the clock by a second was the 
right decision, but, at the time, it was the "obvious" thing to do.

Unless you explicitly install ntp, systemd runs an SNTP-like client to keep
the time increasing (say across reboots) and notify the kernel of pending
leap seconds.  In that circumstance one would expect to see ...59:59 twice.

I guess it was part of systemd?

What software told the kernel that there was going to be a leap second at the 
end of the day?

On my Ubuntu desktop, 17.04 -dev, this is the systemd journal:

Jan 01 07:59:59 X201wily kernel: Clock: inserting leap second 23:59:60 UTC
Jan 01 07:59:59 X201wily systemd[1484]: Time has been changed
Jan 01 07:59:59 X201wily systemd[1]: Time has been changed

No NTP was running.

What NTP is this?

There is security patches to be made to older NTPs.
I had to shut down xntpd on several solaris machines to make them safe, 
as there was no way of configure them to become safe. That was a couple 
of years ago.

Ehm. While off-topic, let me tell you that we had to shut down the last 
Solaris machine we had on the computer club because we concluded that 
there where tools designed to target that generation of Solaris machines 
and take them over. It should not see public internet if powered on.


The network is increasingly hostile, so patch your machines, and don't 
let any machines sit on public network unless you can patch them 
regularly and also do that.


Cheers,
Magnus
