confused with my Arduino YUN

I’m located in Northern California, so I received an Arduino.org Yun. But when I tried to upgrade the firmware, the password was not "doghunter", but "arduino".

After I ran "linup latest", the config screen looks nothing like as shown on the Arduino.org website.

Setting that behavior aside, I continued to try different Yun examples. Some worked … some didn’t.

Question…

while the board says Arduino.org, but the default password is Arduino, which Yun do I have and which IDE should I use?

Thanks
