Update to Push Diagnostics, a utility to troubleshoot Apple Push Notification Service (APNS)

[tperfitt]

I just released an update to Push Diagnostics, a utility that allows people to test if push notifications servers are reachable on a network. One of the tasks when deploying MDM is making sure that push notifications works. Push Diagnostics makes testing APNS servers easy. It is in the Mac App Store and is $4.99, and is a great way to "get the lay of the land" on a new or existing network when deploying MDM.

More info here: http://twocanoes.com/push-diagnostics?utm_campaign=JN13

For testing APNS can't you just run the two commands below or is there something else involved?

telnet gateway.push.apple.com 2195
telnet feedback.push.apple.com 2196

[bentoms]

Nope a little more is needed. http://support.apple.com/kb/TS4264

@tperfitt Thanks!

I'm wondering if there is a Windows equivalent; my JSS is on Windows Server 2012 R2 and I want to confirm that it is able to communicate properly with APNS through our DMZ. I'm getting somewhat frequent APNS feedback errors when deploying configuration profiles and trying to narrow down the cause.

@tperfitt - is the app still functional? when I test, it says failed on the test push from the twocannoes servers.

oh, and the completion message is in error, it shows failed, but your results say all passed.
Version 2.3 (1059)

This may have been a casualty of the migration from Urban Airship to Amazon for APNS. Thanks for letting me know. I'll look into it.

I spoke too soon. I just tried for me and it worked fine for both the test and production servers. Send me the push token and I can investigate further. Send it to support@twocanoes.com.

[bradtchapman]

This is good stuff. Thanks for sharing.

[anthonytji]

im having issues with the push diagnostics page as well, any help?

[abdo_iracheta]

Same issue here, someone can help me with it?, this only happens on just 1 DEP Mac.

[NightFlight]

I don't see any indication that with the latest version (3.2) it does any test push. Just DNS and connectivity checks. That's great, but it assumes that the infra on the Apple side is working. This is not sufficient when trying to crack into an actual problem.

I've emailed twocanoes.

Confirmation back from Twocanoes. It no longer sends out a test push. The author didn't have enough people interested in paying for the product to maintain the certificate updates.
