[Solved] wlan0 and openntpd

Hi,

i recently switched to systemd as initprocess and have a little problem with my timezone, because openntpd is started before a wlan-connection is established.

Is there a workaround for this?

Before using systemd i had an entry in rc.local who started openntpd with a delay of 4 minutes and i know i can use rc.local with systemd, but i think it must be possible to have the established internetconnection as an dependency of openntpd.

Any help is appreciated

Re: [Solved] wlan0 and openntpd

There should be an option to have the NTP service launch only after the network has been brought up.

Actually, that's already the case:

$ cat multi-user.target.wants/ntpd.service 
[Unit]
Description=Network Time Service
After=network.target nss-lookup.target

[Service]
Type=forking
PrivateTmp=true
ExecStart=/usr/bin/ntpd -g -u ntp:ntp
ControlGroup=cpu:/

[Install]
WantedBy=multi-user.target

So there's probably something going wrong at the network part.

Re: [Solved] wlan0 and openntpd

Well, i use openntpd, not ntpd.

Heres the .service from openntpd:

[Unit]
Description=OpenNTP Daemon
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/ntpd -s

[Install]
WantedBy=multi-user.target

I think i see the error

EDIT: I've added nss-lookup.target to "After=network.target " and it didn't change anything (Of course i rebooted).

What systemctl says:

# systemctl status openntpd
openntpd.service - OpenNTP Daemon
	  Loaded: loaded (/usr/lib/systemd/system/openntpd.service; enabled)
	  Active: active (running) since Mon, 27 Aug 2012 20:56:08 +0200; 7min ago
	  CGroup: name=systemd:/system/openntpd.service
		  ├ 441 /usr/sbin/ntpd -s
		  └ 625 /usr/sbin/ntpd -s

Hm, is it loaded twice?!

Re: [Solved] wlan0 and openntpd

is there a reason to use openntpd instead of ntpd?

No.

The wiki says, that openntpd is no longer supported, so i'm switching to ntpd.

It would be even better to switch to chrony.

Re: [Solved] wlan0 and openntpd

I'm not 24/7 online, so it seems to be the better solution. I'll try it out

EDIT: With chrony i have the same problems as with openntpd, only ntpd works correct.
