Ntpd.service gets re-enabled every boot, packaging issue?

(This is a related to https://bbs.archlinux.org/viewtopic.php?id=150415, but different, so I'll post this separately.)
I have systemd, ntp and NetworkManager and networkmanager-dispatcher-ntpd installed. Since this is a laptop, I do not want NTP to start until after I've established a network connection. This is in essence what the dispatcher package is for.
However, I noticed that the ntpd.service is "enabled" in systemd, which means that it starts well before a Wifi connection is established, and, of course, making the dispatcher script useless, since it's already started.
I thought I could simply fix this with "systemctl disable ntpd.service", but that doesn't really work. After a reboot the ntpd.service is re-enabled again. I *think* this is because the ntpd.service file contains the following section:
[Install]
WantedBy=multi-user.target
And the following command shows ntpd.service listed as well:
systemctl show -p "Wants" multi-user.target
Since I'm not that familiar with systemd (yet), my question is: is this what is happening? Does the ntpd.service get re-enabled because it has that "WantedBy" clause in its service file?
Now, if that is truly the case, is this a bug in the ntp package, or should I simply hack the ntpd.service file and remove the WantedBy clause? Or is that not recommended? I looked at the upstream code and the ntpd.service file appears to be Arch-specific, since it's not in the tarball.

ngoonee wrote:After a fresh boot, try searching for ntpd.service in /etc/systemd/system/multi-user.target.wants, which is the list which actually is enabled by you the user.
Ah! I think I found the culprit. Here's the rundown. I call "systemctl disable ntpd.service" and my /etc/systemd/multi-user.target.wants folder no longer has a link to ntpd.service, as you describe.
I reboot and have no network cable connected, nor any "auto starting" wifi connections. After the reboot, still no entry for ntpd.service in multi-user.target.wants.
Then, I make a wifi connection, which triggers the call to the networkmanager-dispatcher-ntpd script.
Voila: a link now appears in multi-user.target and "systemctl status ntpd.service reports that it is enabled. Therefore, the networkmanager-dispatcher-ntpd script (or, I guess this could be the case, NetworkManager itself?) is re-enabling ntpd.service...
The dispatch script essentially makes this call when a connection is established:
gdbus call \
--system \
--object-path /org/freedesktop/timedate1 \
--dest org.freedesktop.timedate1 \
--method org.freedesktop.timedate1.SetNTP true false
I'm not familiar with "gdbus" - could this be re-enabling the systemd service? Or would it be NetworkManager itself that's re-enabling ntpd.service upon establishing a connection?

/etc/hosts works but gets overwritten every boot

On my system (10.6.8) I can edit /etc/hosts and the changes take effect immediately. The problem is that every time I reboot, my changes are overwritten. Does anyone know what could cause this? BTW this is the exact same unsolved issue found in this dead archived thread.

"servy" is a computer on my lan that uses DHCP and registers its name with my router which serves DNS. If I comment out the line for "servy" in my hosts file, it immediately takes effect and I can successfully ping it, or lookup its address with "dscacheutil -q host -a name servy", but as soon as I reboot, the /etc/hosts file no longer has the comment in that line. It's like there's a "last known good" copy of the hosts file somewhere and OSX or some service is restoring it every boot.

How do I get a service to be enabled only on a reboot?

Hi!
Here's what I'm trying to do:
I have a transient service, which makes configuration changes on the system early in the boot process. However, when I install(import in SMF) this service on a system, I do not want it to run right then as it is too late to make those configuration changes on a running system. I only want it to run at boot time on the next reboot.
Options I've considered:
Option A:
1. Create a manifest with create_default_instance_enabled=true
2. Put my xml file in /var/svc/manifest/site/mysvc.xml
I do not want to import this at install time. On first reboot, it picked it up. After that, during testing, I deleted it from the repository, left the service in /var/svc/manifest/site/mysvc.xml, and rebooted, SMF didn't pick it up.
Option B:
If I instead have a manifest with create_default_instance_enabled=false, and import this.. How do I then make SMF create an instance of this service ONLY at boot time.
I've seen other posts which talk about putting your manifest in /var/svc/manifest/site/mysvc.xml or in /var/svc/profile/site.xml. I'm not sure what the difference is between these 2. Unfortunately, I haven't found any documentation on this.
I'd greatly appreciate some pointers on getting this right.
Thanks!!

Option A:
1. Create a manifest with
create_default_instance_enabled=true
2. Put my xml file in

Option B:
If I instead have a manifest with
create_default_instance_enabled=false, and import
this.. How do I then make SMF create an instance of
this service ONLY at boot time. I think you could use svccfg to set the :default general/enabled to 'true'. That wouldn't make it run, but it would try to run on restart.
I've seen other posts which talk about putting your
manifest in /var/svc/manifest/site/mysvc.xml or in
/var/svc/profile/site.xml. I'm not sure what the
difference is between these 2. Unfortunately, I
haven't found any documentation on this.The first is for your manifest. That describes your service. You'll notice that most sun services are not enabled in the manfest.
The second is a profile. A profile is brought in usually at first boot to configure a system. It may enable or disable services. Notice that there are two "generic" profiles. One turns on most things, one keeps a lot of stuff turned off.
There are 3 site profiles that can be brought in automatically: generic, platform, and site. You can create a site.xml and the first boot that finds it will load it. So at jumpstart time you can put manifests you need in the manifest area and enable/disable what you want by the site.xml.
If you use a site.xml at jumpstart time, you can't use it later to modify things.

I have to clear this everytime I boot up?

With that one, perhaps first try uninstalling and reinstalling your MobileMe control panel. Does that clear up the error?

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Thaks for your reply.
I got this interface name from ip addr, how it should be named if 'enp4s1' is wrong?
journalctl is here: http://bpaste.net/show/104083/
I found only one string realted to this device name:

Is there some other logs where it can be checked?

OC4J as a service getting stopped

Hi,
We made OC4J as a service but the service is getting stopped for every 2 days. Where can I check the log for this...
What are the changes I need to make to keep it running continously..
Thanks

Hi I used the following command to make it as a service
"C:\Program Files\JavaService\javaservice.exe" -install "Oracle BI OC4J Server" "C:\Program Files\Java\jre1.5.0_11\bin\client\jvm.dll" -XX:MaxPermSize=128m -Xmx512m "-Djava.class.path=C:\OracleBI\oc4j_bi\j2ee\home\oc4j.jar" -start oracle.oc4j.loader.boot.BootStrap -description "Oracle BI Oc4J Service"
I think this doesnt have a log ..

Mac shows iCloud password popup every boot.

I get this popup window every boot.
Why does that window show up?
and How can I fixed it?
+
I reinstalled OS X 10.9.3 today.
Before reinstalling, I didn't see that window.

You are not alone.
This needs an Apple iCloud Guru to clarify & solve.
This first showed up for me in Mavericks 10.9.3, and was not fixed in 10.9.4. Neither was a beta version. Updating to a later version of the OS also fails to resolve this suggesting that perhaps it is the iCloud authentication server that is broke -AGAIN!
Unfortunately the Apple helpdesk knows nothing of this issue, or are trying to keep lit under wraps.
My guess is that some of the downloads from Software Update are in fact experimental builds, Noting that is some countries Apple is playing with two factor authentication, perhaps we have been hit by a build that is trying out an alternative authentication method, that simply keeps failing. Though perhaps it is geolocation triggered, as doing a clean install achieves no improvement.
ICloud, which I prefer to call iClod still has bugs, but unfortunately those best able to fault find the authentication system are not available to users, so getting this bug fixed will involve further contributions from more clued up users.
Unfortunately it seems that the failure manifests in several ways, with at least 3 different, but cryptic seemingly random dialogue boxes appearing in response to entered passwords, and also no apparent response at all, i.e., no change.
What is odd is that one can be successfully signed in to iCoud, able to manage ones account, but unable to successfully verify ones password in the preference pane. Looking deeper in the console loads there is reference to a file not being able to be written. So is this a permissions issue, or is the preferences file to be written missing from the bundle from the iCloud bundle.
And even more oddly when one intentionally enters an incorrect password in the password verification dialogue, iCloud seems to correctly identify it as an incorrect password, suggesting that iCloud recognises a correct password but then fails to complete the verification transaction.
Note this iCloud preference pane userID password verification process is not documented anywhere that I have been able to discover. Is it another inadvertent FEATURE of OS X that was mostly deprecated because it did't work as expected?
One day Apple will wake up and instigate a dedicated iCloud help call centre tasked to ensure that all users have access to this service which has become intrinsic to ownership and use of a Mac.

Volsnap - Shadow copies deleted every boot

Am using Win7 Ultimate Sp1 32 bit. Since last week (bunch of Windows updates),
upon every boot, I get a volsnap error:
shadow copies of volume C: were deleted because the shadow copy storage could not grow in time
and my system restore points are deleted.
I have 150 GB free space on the drive and System protection is allocated for 8% of the drive. Coinciding with this issue is the fact that I'm also having problems resuming from sleep. I'm not sure if the
shadow copy error also occurs on resume from sleep

Please verify that the programs (Ubuntu, Mint, Boot-Repair, etc.) you are attempting to use, support the Atheros AR8161L gigabit ethernet controller natively. Not all operating systems and software programs support every network device and/or configuration otut of the box.

T2000 not enabled to boot from cdrom

Dear,
I have new T2000 and want to install Solaris OS but I am not enabled to boot from cdrom. When I run "ok boot cdrom" get following errors -
Rebooting with command: boot cdrom
Boot device: /pci@7c0/pci@0/pci@1/pci@0/ide@8/cdrom@0,0:f File and args:
Can't read disk label.
Can't open disk label package
ERROR: boot-read fail
Evaluating:
Can't open boot device
So I searched on google, I got some tips like upgrade the firmware and run the "boot cdrom -nowin" command, I tried alls but no luck ...
"probe-ide" still shows "Device Not Present"...
Please share me your experience about this problem if you have....
///Thanks
Mohammed Tanvir

Run "boot cdrom" twice in quick succession. It worked for me, and it might work for you.

After upgrading to Mountain Lion, Interface builder starts up with an error every boot.

I've got a late 2008 Macbook Unibody 13", and a few months back I upgraded from Snow Leopard to Mountain Lion. Ever since the upgrade, at every boot up Interface Builder starts up with an error. I've just ignored it mostly, but now I'm getting annoyed with it. How can I find the programs that start up every boot to research this, or stop it from loading Interface Builder every time?

You have to delete it using the minus sign at the bottom. The check/un-check is for hiding items.

My 2008 iMac will get to the white boot up screen and has the loading circle and then it will freeze. And will freeze when attempting to boot recovery or bootable disc of Mavericks

Hi there, I have a 2008 iMac 24' 3.06 Intel Duo with 4gb ram. And yesterday it was working totally fine and jolly with no issues. Then I noticed there was an OS X update for Mavericks, so I finally decided to do it, and once it was rebooted it went to like the grey screen and I could move my mouse, just nothing else was there. So I tried to restart it, and then it booted up, but was really laggy, and so I decided to restart it and try again, this time the iMac froze at the login. So I decided to take it apart, pull the 500gb hard drive, connect it to my MacBook Pro, and then formatted it in Disc Utility. From there, I opened the Mavericks installer on my MacBook and then installed it to the iMac's hard drive via usb hard drive enclosement. And once the install of Mavericks was completed, I put the hard drive back into the iMac and tried to boot it. It now boots up to the white screen with the Apple and the loading circle underneath the Apple and then it freezes and doesn't go any further. So then once that happened, I turned it off and tried to boot it into recovery mode. Then it freezes on the screen with the Apple and loading circle below it. Then out of desperation, tried to use a bootable disc of Mavericks to see if i can at least get the iMac to boot up again, with no success. It froze at the same point again. So now I reach out to the Apple Community to see if anyone else has an idea on what I can do or if anyone had this issue and what they did to resolve it. Any help would be great. Thanks.

mddcfilms and Pat75, I'm having precisely this same issue -- no booting but spinning and freezing gear under the Apple logo. Have either of you come to a resolution? Here are my details:
iMac, Early 2008, 24”, 3.06 GHz, 4GB
September 2013: Nvidia GeForce 8800 GS GPU repaired, HDD replaced with Western Digital 2TB
21 April 2014: Erased HDD with Disk Utility on Mavericks USB; clean installation of Mavericks from the USB. Process completed without issue, including registration process. After a minute or two of poking around, machine shut down immediately (not through the shut-down process).
Since then it will not boot up. Grey screen and Apple logo appear, with gear spinning; the gear freezes, then the machine tries to boot up again. Occasionally I’ll hear “To use English for the main language, press the return key.”
I’ve tried booting into Safe Mode; same gear freeze and restart.
I’ve tried booting to the 10.9 Recovery disk; same gear freeze and restart.
Tried booting from Mavericks USB; same freeze and restart.
Tried booting from 10.6.3 DVD; same freeze and restart.
Ran Apple Service Toolkit (at Stormfront in the UK), which turned up nothing in error.
Started in single-user mode to test HDD and RAM, which are fine.
Started in verbose mode to check logs; some error messages but nothing seems crucial. After the log screen, the grey screen and Apple logo appear, gear spins, and then freeze.
Cannot get to Apple Hardware Test (vintage machine too old?)
Cannot get to Target Disk Mode with my MacBook Pro
Ideas: Potential booting flaw in Mavericks installation. Firmware incompatibility with Mavericks. Hardware issue in Nvidia GPU (known for problems). At the moment I'm hoping that it's a Mavericks installation or firmware issue, though I suspect the Nvidia GPU has blown up on me. These graphics cards are known for being pieces of junk, so I may try installing the lower spec ATI Radeon 2600 GPU if I can find one at a reasonable price.
Anybody else have precisely these problems or have any advice?

Windows 8.1 Ent eval enabled Secure Boot I think

I want to get my laptop back to its original format.
Currently dual booting Windows7/8.1
During the installation of Windows 8.1 Enterprise evaluation it paused to say it was going to enable secure boot. I did'nt think much of it I thought I could change it back from the bios. Did it flash my firmware? I checked the system status
with msinfo32.exe; was legacy mode and with powershell; secure boot not supported. I don't have any options to disable secure boot in the bios nor from within Windows -"I know how to disable it in windows 8.1". I can't boot a foreign
operating system, but I can boot a Microsoft OS which sounds like secure boot to me. I want to get it back to running Windows 7 dual booting with Linux. I use both at work and need both. I made the mistake by loading the Eval on my primary
laptop. I read I need to revert back to Windows 7 completely, formating and re-installing the OS. Will this clear my secure boot simulation issue? I have not changed the partitions or removed any O/S's. What's the best way
to proceed?

Hi,
I want to explain that, Secure Boot is indepent with system, you can disable it in UEFI interface.
To disable Secure Boot, you can follow the steps below:
1.Before disabling Secure Boot, consider whether it is necessary. From time to time, your manufacturer may update the list of trusted hardware, drivers, and operating systems for your PC. To check for updates, go to Windows Update, or check your manufacturer's
website.
2.Open the PC BIOS menu. You can often access this menu by pressing a key during the bootup sequence, such as F1, F2, F12, or Esc.
Or, from Windows, hold the Shift key while selecting Restart. Go to Troubleshoot > Advanced Options: UEFI Firmware Settings.
3.Find the Secure Boot setting, and if possible, set it to Disabled. This option is usually in either the Security tab, the Boot tab, or the Authentication tab.
4.Save changes and exit. The PC reboots.
I found an aticle that teach how to install dual-boot Windows 7 and Ubuntu 12.04 on a PC with UEFI hardware:

Hope this helps.
