How often does OS X sync with an NTP Time server?

By default, how often does OS X Tiger sync with an NTP Time server? I am monitoring my systems with the tcpdump command and I never seem to see my Macs trying to sync with our time server. It seems like it only syncs at boot or when the Time & Dat System Pref Pane is opened manually.

Hi there,
I have no idea...
but if you are having a drift problem then have a read of this...

How effective does iPhone 4 sync with Microsoft Exchange

Hello,
Sorry for a possible repost but I did try to search for this topic but didn't find anything.
I'm really into the new iPhone 4 to use as a business phone. I have a Dell PC with Windows XP. The most important thing for me regarding iPhone is that the sync with Microsoft Exchange is flawless.
Can somebody (who has an iPhone and Microsoft Exchange) tell me how effective the sync is with iPhone and Microsoft Exchange? Does the e-mail sync quickly and how does the sync work with contacts and calendar. If I put a new calendar item in Outlook does it appear on my iPhone without me asking it to sync and etc.?
Please do share your experience

Can I put the sync settings on the iPhone 4 to only sync between certain time interval? Say, monday to friday from 08am to 7pm?
If you want push sync, then, no, you can't set a time interval. The entire point of push support is that the server notifies your system whenever something new arrives or something is changed. If you want to control when your iPhone contacts the server, then you can't use push. You can have the system fetch data at a set interval, or you can set to do it manually, if you prefer, but there's no setting where you can set a time window.
And can I put the sync settings only to store a certain amount of e-mails? Say the 100 newest?
You can set how may days of mail to sync, and also how many emails to show.
You might find the the user's guide helpful in learning about features and settings:

HT1539 How often does your download end with errors - after 3 hours waiting for a Blue Ray download???

I'm at 95% under windows and 80% on my MAC. Is this anyway to run a "business Totally Absurd" !!
error -1303, error -50. have read all the forums on this... nothing works reliably. I can rip the BluRay faster than this importing process... takes days sometimes to finally get a full download.
Sometimes I get to 100% downloaded (xx.xx GB of xx.xxGB) and it sits there for hours, sometimes if even fails at that point. Totally unacceptable.

How often does the Apple TV sync with updated home sharing playlists?

I am trying to use several Apple TV's at my business for content management throughout our campus. I want to be able to have a playlist of pictures and videos that is easy to update. Can anyone tell me how often the Apple TV syncs with the home sharing network for an updated playlist? It would be very inconvenient if the only way was to do a reboot on every device each time content was updated.

Welcome to the Apple community.
I can't really say for sure how often the Apple TV updates its shared libraries.
I do however know that once the Apple TV as completed playing something, it will sync with the shared library in order to update the play count. So I'd be reasonably sure that the shared library is updated at least once every time something is played.

How often does iCloud sync ?.

How often does iCloud sync my devices ??

Your Mac's address book, on the front page - was the address you added inside a group that is listed in the general category "iCloud" or "On my mac" ? If the latter, then that doesn't sync to iCloud. If iCloud, you might try a small editing change to the entry, like erase last letter of last name, get out of address book, go back in and put the last letter back in. That should force a sync.

How often does Firefox Sync back-up data? I see there is no preference selection allowing you to change the pre-set frequency (whatever that interval may be).

How often does Firefox Sync back-up data? I see there is no preference selection allowing you to change the pre-set frequency (whatever that interval may be).

However, the sync action only triggers every 60-minute and there is no user-configurable option provided. Although one can put a Sync icon onto the toolbar for easier access, it is still far from practical needs.
To unlock this limitation, do the following:
1) Type “about:config” at the address bar
2) Search for “services.sync.syncInterval”
3) Change the value from 3600000 (milliseconds = 3600 seconds = 60 minutes) to any value (in millisecond) of your choice
4) Close and restart Firefox
The Sync action will now trigger at the interval you just set.

How often does your CF instance need to restart?

I'm considering CF as an application solution for a critical
department..and not having much experience with it , was wondering
how often does the CF service need to be restarted ? hourly, daily,
weekly, monthly?????
i've had experiences with other app servers that at times
could be quite annoying...and would like to get some real world
input on the issue.
Many thanks..

It definitely depends on how you code and set up the site.
I've worked at a few places where the only time we restarted the CF
servers (or services) were when we actually switched servers. Other
places we had scheduled maintenance windows and did the restarts
then, sometimes they were needed while other times it was just for
the sake of doing it.
You should also take into consideration the OS reboots, for
Win2k3 or 2k8 you'll sometimes need to install critical patches
which need to restart to take effect. I don't know about UNIX or
Solaris and the others.

My first gen ipod mini does no longer sync with itunes 11.0. It says "cannot write or read". Ist this the end?

My first gen ipod mini (that I use in my car) does no longer sync with itunes 11.0. It basically says "cannot write or read". Is this the "end of life" of that ipod?

You mean you can't get to the Summary pane?
If you have iTunes 11 turn on the Sidebar. Go to iTunes>View and click on Show Sidebar. You can also do a Crtl+S to show the sidebar. The sidebar is where Devices appears. and Control+B to show the Menu bar

How many device can one sync with iPhone? I own a Mac Pro and an iMac desktop. Can I sync with both machines?

How Many devices can I sync with my iPhone? I own a Mac PRO and an iMAC. Depends on where I am, I will plug my iPhone to either of the machines. I haven't sync with either machine yet.

Please explain how one would accomplish that feat.
There's not much to explain. When a device is connected, you see the row of different categories across the top: Summary, Info, Apps, Tones, Music, Movies, TV Shows, Podcasts, Books, and Photos. For example, it is perfectly safe to sync one iOS device to the Music category on Computer A and no other computer, and the same device to Photos on Computer B and no other computer.
You might be confusing what I'm saying with one iOS device enabling sync to the Music library on multiple computers. That is a huge no-no and will result in the disaster being suggested. But I am not talking about that, I'm talking about the opposite arrangement. What I am describing preserves category exclusivity. It turns out that exclusivity at the category level, not the computer level, is what really matters.
As long as a device is synced to a given category on only one computer, it doesn't matter which computer it is or whether that computer is different than the ones synced to on other categories. The instant a given category is enabled for syncing on more than on computer, that is where the trouble starts.

Trying to do so is asking for trouble. Don't do it. Move the content you need to one machine and sync only with that machine. If you don't, you'll be back here asking how to fix the mess and recover all the stuff you lost...
I will agree that it is something you should only do mindfully. But if you do make sure each category is syncing to only one device, there will be no data loss and no mess.

How often does Cisco release signature updates?

Hi, i would like to know how often does Cisco release updates for the Signature engine for the IPS appliances? I was not sure to make the auto update from Cisco.com to be every-day, every-hour or once a week?
Also can you advise me of the recommended setting for Bypass feature for the interfaces?

Since the auto-update checks go out the management interface it maybe better to have it set for every hour. That way you wont have delays in the critical updates. Assuming you are in inline traffic mode, setting the bypass to "auto" is the recommended setting for interfaces. That is also the default.
