WTF?!?! One Station Claiming Statistics On ALL Ships?!?!
« on: 17 March, 2013, 11:08:58 pm »
Hello all,

 I just noticed a very odd situation. 2 ODAS buoys within my area of coverage are being listed by my system as being received by AISHUB. I found this odd as I am the only receiver in my area (West Coast Of Vancouver Island) ??? ???. On a whim, I checked the statistics page and I noticed that 1 station (2156 - Santa Barbara, CA) is claiming stats for over 17,000 ships spread around the world?!?!?  :o :o :o :o How is this possible? Does this station have receivers spread around the world, or is he/she repeating back to AISHUB everything AISHUB is sending on his/her TCP connection? ::)

 I suspect that if I cut my feed to AISHUB that the ships/buoys in my area that 2156 is claiming at their own will disappear. I can't believe that person/station is sending everything back. I tried the raw unfiltered feed when I started with AISHUB and my computer couldn't handle it!

Cheers!
Mike

Yep, I'm seeing that as well.  I suspect that station is just accidentally misconfigured to echo back their feed - annoying in how it screwed up statistics (and presumably, doubles the amount of data the aishub servers need to process), but at least it's not fake positions.

Yeah, That's what I figure as well. If the station is running Shipplotter, I think that program just spits out everything it receives without any concern as to where it came from. I saw this with one of my feeders to my AIS project. I'd send him raw data (as he also is my decoder backstop) and I'd get that data right back a couple seconds later. Took us a short time to realize Shipplotter (what he uses) was acting like a repeater. He now runs AISServer from SiiTech to control what feed goes where. I have a feeling that the Santa Barbara station may have to do the same thing (AISDispatcher works wonders for this sort of scenario).

Yeah, my stats are screwed up as well. You can see where the one line on each graph promptly hits 0 on the run when that station came online. Hopefully Peter sent the station an email alerting them to the situation so they can rectify it. Heck, I'll even provide email assistance if the station owner needs/wants it!

Cheers!
