Public bug reported:
Binary package hint: ntp
Hi.
In syslog cut below you can see that @ 21:10:12 VPN became up and running.
But 4 minutes later - @ 21:14:14 - ntpd service successfully synced time with
server 91.189.94.4 and then - bound to my tunnel interface.
30 seconds after that NM's VPN detected dead peer and found that "no VPN
connection was active".

If fixing this issue is too complicated task, then here's a small workaround:
May be it's better to make an option in ntp's config file like "work_as_server
= 0", thus preventing it from binding on all existed interfaces?
I don't think that standard desktop system requires ntp-server, only ntp-client.
Thanks anyway, will wait for comments.
