S9 Antminer's root password "admin" - change immediately!!!
I now own a #S9 #Antminer from #Bitmain for some weeks (already). It runs really loud and I turn it only on when I'm out of house or want to have it running. It has a nice web interface and even #SSH with root (some #Linux embeded system). I setup quickly everthing and mining #Peercoins is working as expected (I run it in eco-mode). But what I later found out is that the SSH root password is simply "admin" which is a well-known password.
So here is my advice: If you intend to buy and run it (locally or on public Internet) please *do change* your SSH password! If you fail to do so, somebody might be able to change your pool login data and then he is receiving the coins you want to mine on your electricity bill! And I'm sure that he will then change root password to his own so you have to (somehow?) flush the memory to have factory-default settings (including password, I hope) back.
Here are some pictures of my miner, including screenshots which is just below my computer table (and it can be very noisy): cloud.mxchange.org/index.php/s… #Nextcloud

Wow, I have seen an #Bitmain #Antminer #S5 for 519 EUR which makes 1150 GHashes/sec. and may sound a lot. This is 0.45 EUR per GHash. Compared to my #R-Box miner with 32 GHashes/sec. it has 1.87 EUR per GHash. This means that the larger miner is more efficient (more coins mined for lesser money per GHash). Well, now you need to calculate energy consumption in: R-Box=30-50 Watts, S5=590 Watts.
