How to Power Nap, sleep & AutoPowerOff play together?

Hello

Configuration & system background: This is related to a network of small business for which I wrote a custom backup script that I have tested before deploying. The script rsyncs selected files from the workstation (2013 Mac Pro, OS X 10.11.6) on the server via wifi with an Airport Extreme. SSH without password is used by root to connect from the desktop to the server. The server is a Mac Mini (OS X 10.11.6/Server 5.1.7) 2014 end set not to sleep.

The script is loaded from launchd and is set to run at designated times throughout the day and night. It seems to work fine when my computer is awake. I read launchd to run programmed events when a computer wakes from sleep. What seems really do experience during the night (when I'm personally in mode "sleep"), it's that the script will run intermittently (i.e., not to the regular time) but it fails because the first use of SSH (of rsync) will expire. Full hostname of the server is used in the script, Vice President of the IP address.

On the workstation, Power Nap is enabled and the computer is allowed to sleep. pmset standbydelay = 10800 (3 hrs) and autopoweroffdelay = 14400 (4 hours). My understanding is that information in Mail, Notes, Contacts, etc., will be updated only if these applications are running. on my computer, I think that Notes was the only one running all night.

Assumptions:

(1) power Nap allows the script runs because the computer has partial wake up during the night.

(2) the script is falling in the night economy modes of energy of the workstation do not allow DNS queries.

Then test: I got standbydelay and autopoweroffdelay every 12 hours and see if the script runs correctly this evening.

Issues related to the:

(1) my assumptions seem valid?

(2) which of these modes of standby energy disables searches DNS or other network activity?

(3) someone has a link to the proper documentation describing the technical inter-agency interactions when Power Nap is active?

Thanks in advance.

UPDATE: change the standbydelay and autopoweroffdelay every 12 hours seems to allow the script to run. Execution does not at the scheduled time, so in my opinion, it happens when something else wakes the computer (the NAP is enabled). However, it seems much more likely to be broken pipes at night that I do during the day, and I'm this troubleshooting.

On the server, I confirmed by the newspaper pmset that computer don't is not reported as being put to sleep, so now I am bad shooting other things which could cause a part of the network to not work properly.

So I think that I have answered my first question (i.e., valid assumptions), I'm still looking for help to question 3.

Thank you.

  • Its mixed? While playing the slide with audio, if the customer has hit a tab with audio interaction, two sounds will play together. How to avoid what is happening?

    While playing the slide with audio, if the customer has hit a tab with audio interaction, two sounds play together, which is not a good customer experience.

    How to avoid what is happening? Placing a marker can help, but cannot solve the problem when the compliant/no intentional user, press tab.


    Better, if the presenter can triggle tab automatically at some point, or click interaction, no game bar function.

    Hi Louie,

    My sincere apologies for not being able to help on your previous question.

    Now, that the Interactions are concerned, they were initially designed to be placed as standalone content on the slide.

    Also if you try to resize your interaction and place it on the slide as well as other content/objects released published will always give a priority to the Interaction that it deemed to be a specific slide of Interaction.

    In the previous project, you shared, you try to time the Interaction with PowerPoint animations and wanted it to appear later on the set of slides, rather than on the start. But, as explained above, presenter honored not this setting in your project, because he in fact has considered a slide of interaction and display interaction since the beginning of the slide room itself.

    Also the number listed in this thread is concerned, there is no direct way to do it but I would like to suggest something that might help.

    If you want to keep the interaction on your slide and other content, Interaction will be available at the beginning of the slide. Surely there is no way that delaying his appearance, but you can still use animation related to Interaction in another goal. Within your presentation-> playback option settings, you can enable the feature of 'Pause after each animation' (see screenshot below). It will essentially help you achieve the function of auto-faisant a break from your animations, using your narration would automatically stop, just before you claim in your narrative and inform the learner to click on the different tabs of the Interaction. All you have to do is your narration and animation correctly so that the slide play does not break too many times in the time interval. Hope you find the idea of what I'm trying to say.

    Please mark this answer as being correct, if you find it useful. We would certainly look at such scenarios to be achievable directly at the request of our updates and later version.

    Thank you

  • How to activate the Sleep function to put the computer to sleep if a program is open?

    I have Windows Vista basic on a desktop Dell 530.  I found that if I have a program or application running (such as I-tunes or windows media player) then the Sleep function will not put the computer to sleep.  How to activate the Sleep function to replace these programs and put the computer to sleep?

    Note: This is how it was with windows XP, the Sleep function would put the computer to sleep no matter what was running, he was reliable, if you left the computer and I forgot that you had something running.

    Thanks for your help.

    Hi kevino4130,

    If you disable sharing on your computer (not only the power settings) of media, it should allow him to enter the mode 'sleep'.

    See if that does not solve your problem and let us know.

  • HP Pavilion Windows 8 g7; headphones and speakers always play together.

    I've had this laptop for quite awhile and a while ago my laptop headphone stopped cut speakers occasionally and they always play together now. I tried to find a solution to this on the forums, but it is not a problem with the two be affected as peripheral to read. I think the headphone jack can be broken, and it is not actually save my headphones plugged because it says on the playback devices that they are not plugged. I think that if there was a way to play sounds through the mic socket that can fix this, but I can't figure out how to do this. Any help would be great, thanks.

    Hello newtohp4567,

    I understand that the speaker and the headphones play at the same time.

    Go to Device Manager and uninstall the driver IDT audio in audio, video, and game controllers.

    Restart the computer.

    As the computer starts up, press the F10 key.

    When the BIOS setup utility charges, press F9 to set the default values and F10 to save and exit.

    When you start the computer to windows, it will load the audio driver.

    Here is a link that will show you how to get to Device Manager.

    If you still experience the problem, go to HP.com and update the BIOS.

    Here is a link to the update; you will need your product number.

    You can find this information by holding the FN key and pressing the ESC key.

    If you are not able to correct the error by making these changes to the software, I would call HP and make them fix the appliance while it is still under warranty.

    Here is a link to a number to call HP.

    I would like to know how everything goes.

  • How can I say ios10 music playing ONLY what is loaded on the phone?

    How can I say ios10 music playing ONLY what is loaded on the phone? There was a way under ios9, but I can't find anything on ios10. When I shuffle a kind (like ROCK that has only 4 artists, I chose it), I want to shuffle only what is loaded on the phone, not what's on my mac (in the cloud)... I load only a few artists both because of space constraints. I have over 200GB of music on my mac...

    I don't want to see the playlists and artists who are not loaded on the phone either, but I can't find how to solve either!

    Launch the music application and go to the library > music downloaded. This shows that what is stored locally on the phone.

    I speak not of advertising videos.  It seems that there is a new trend that sites add the AutoPlay videos as part of their normal textual content.  It's really annoying to try to read the article and have this semi-connexes video game.

    How to reset many Solitaire games played and won Matches of the counters?

    Hi Keith,

    Found an answer for Vista, that should work for you in Windows 7.

    To reset the game statistics, you must delete some files. These files will be re-created automatically the next time you play the game. The files are located in the following location: 'C:\Users\[UserName]\AppData\Local\Microsoft Games\ [game]", where [username] is the name of your account and [game] is the name of the game (in your case, Solitaire). Just delete the contents of the folder, but DO NOT delete the folder itself.
