Yesterday I made OS X Server, on Mac Mini, for Xcode Continuous Integration.
Today, by scanning my local network, I see that this Mac Mini is having port 2012 open with this raid-ac.

I googled but can not find any info regarding this raid-ac.
I suppose that this raid-ac is used for this Xcode Continuous Integration feature.

Can somebody provide more info about it ?


As far I know RAID, it's a way to store data across multiple disks (HDD) acting like one.

There are multiple standard levels of them as explained on this Wiki (might be geeky as you say).

Based on that knowledge I would say the services works with redundancy in order to run smoothly. As you say yourself: Continuous Integration (as in, without interruption)

Please check source below:

UDP port 2012 uses the Datagram Protocol [red. that's what UDP means], a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 2012 makes possible the transmission of a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 2012, UDP Port 2012 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 2012 to process any errors and verify correct delivery. source

    You're only making suppositions right ? References would be great to support your answer. – Matthieu Riegler Apr 9 '14 at 9:01
  • @MatthieuRiegler I was, until my edit looking for references or information. TBH, it's amazingly hard to find. – Rob Apr 9 '14 at 9:13

    I am familiar with RAID, but I doubt that raid-ac have anything with RAID. I do not see the connection. Maybe this raid-ac is used for developer.apple.com/bonjour ? – WebOrCode Apr 9 '14 at 9:25

    @Rob The info and link you’ve added in your edit say nothing particular about port 2012 or raid-ac, just generalities about UDP. – Édouard Apr 9 '14 at 9:30

    +1. I also did an intensive research and find nothing but standard generated text like your edit. That's really strange. – Matthieu Riegler Apr 9 '14 at 9:31
