how does the network side of pogoplug works ?

by **anorphirith** » Sun Apr 07, 2013 6:00 pm

Hi, I'm trying to understand how pogoplug works.
How pogoplug servers are able to connect to a pogoplug without requiring a static IP or a DNS. and which protocol they use to connect to the pogoplug SFTP, ?

Thanks !

There is no direct connection because there is no port forwarding.

So I believe, the pogoplug connects to my.pogoplug.com and provide its svcid (button of pogoplug). Then when you connect to my.pogoplug.com (with matching svcid), my.pogoplug.com, connects the two connections with a tunnel.

Something like this:

Computer--------------------->my.pogoplug.com<-------------------------------PogoPlug
(connects the tunnel based on svcid)

I've been having issues with streaming my MP3s consistently through the iOS app. I don't think its anything on my side (plenty of bandwidth on both sides), however it still buffers every once in a while (but it seems like it depends on the time). My theory is its resources on the my.pogoplug.com side that's the problem.

Just my opinion.

[Edit]

A tunnel gets created with a interface name of "xce0". Run ifconfig.

Wow thanks for the great response, I looked up online but couldnt find a definition on svcid. What is that exaclty ? Thanks

It is a unique identifier

so what kind of protocol does pogoplug uses to connect ? is it a VPN?

by **moonman** » Tue Apr 09, 2013 4:24 am

My guess is that it's an unencrypted tunnel, so no VPN

Hmmm...you got me wondering. Is my data traversing the internet unencrypted?

I think I might have to open a support ticket to get this question answered.

how using a VPN removes the need of a static IP or a DNS ?

by **moonman** » Mon Apr 15, 2013 8:19 am

It doesn't remove the need for DNS, but static ip is not necessery because your pogoplug will start the connection.

by **anorphirith** » Tue Apr 16, 2013 10:37 pm

So the pogoplug updates the server everytime the static ip changes? Because ultimately its the server that will call pogoplug to connect once the user inputs its credentials on the website
