Yeah I just did that, thanks
I'm still amazed how someone stole my miner just like that Tongue

Oh well,lesson learned, don't leave miners with factory password Tongue

It could that or it probably overheated and lost settings. This happened to me with S1 and recently with one S7. I did not even reset anything, just did a hard reboot.
People were stealing stuff from S1 because it used less secure (old) cgminer version.

BTW, S1 in march of 2014 was producing twice as much BTC/day as S7 does now, bitcoin price was two-two and a half times as much as now and machine price (S1) was three times less. How does this compute?

HOWEVER: I think that there ARE people on btctalk which try to load some crap to your computer. This is for sure.

yeah its insane, but if i remember correctly (maybe im wrong) diff increases were brutal in the s1 days. I bought an s1 and that made great roi, it was running next to a couple gpu's who were mining alts. good days

Yeah, the price of gear these days is a bit absurd. $1,600 plus is a lot for something that probably only cost Bitmain $100 more to make than gear that they sold for $300. I'm quite amazed that they have no competition selling to the public right now.

Whats most amazing is that the miners these days use so much more electricity than previous models to mine a single coin its insane. Even with 0.25W/Gh you need 10Kw and $7,000+ in gear and PSUs just to earn .25Btc per day. Its about to get a lot worse in the next few months too. If we do a few more 10% jumps were all going to be mining at a loss soon enough... Undecided

I use teamviewer on my local subnet and never had a security issue in two years.
If you hook your miner straight to the internet you will get hacked.
I would notice my Linux machines getting hacked pretty fast, it would overload my internet connection when they started using it to push a crapload of data and Comcast would just block the ip.
TeamViewer all the way for me.

I've heard of people having their wallets stolen while having Teamviewer available on their machine, not sure I'd trust using it with my equipment ( or at least not with the default configuration - short username/password).

Like I mentioned a few pages ago in this thread, a home VPN is so easy to set up with a Raspberry Pi, and most modern routers even offer the feature to enable a home VPN. Much safer than just port forwarding and relying on your username/password being secure to avoid hacking, at least with key-based VPN authentication. Plus, if you have multiple miners to monitor you just navigate to their IP addresses, rather than trying to set up different ports so you can access each miner over the internet.

How do you setup VPN with RPi, I have a RPi laying around that I could use?

When I set mine up, I followed this tutorial. Didn't have any issues when I followed this tutorial a few months ago.

Go Big or Go Home.....

On another note, with all these ' Batches' being all random Hash rates. I'm guessing their fab process and hardware is just total crap and can not maintain an engineered and standardized output.

Looks like they are testing a few then slapping a # on it then moving to another set. Laughable.. Only in CHINA.... Cheesy

No wonder everything from there is utter sheyt and brakes in no time.

Were those 3 x S7's you have connected together done with factory 18 pin ribbon cables, J4bberwock 18 pin ribbon cables or 18 pin ribbon cables you made yourself?

These are S5+ cables

Did you attach any fans to those PSU? From what I recall I don't think those PSU have fans of their own.

Yes. 2x 12cm fan
https://bitcointalksearch.org/topic/gauging-interest-in-a-s5-3xs7-specific-power-supply-breakout-board-1178099

just combine 2 in 1 .... 6 blades using 1 controller board, both same batch 5 same blade ver #.

noticed that it runs slower than individual controller with 3 boards .... hmmm thoughts ?

i always change the pwd when i get the new shiny miners.

yes, i do agree it's related towards more to freq for hw errors not temps but talking abt temp, i find it that they work best around 60 deg C

batch 5 i got v1.3 boards but my batch 3 i got v 1.6 boards ...hmmmm

Exactly...

I had an S5 of mine hacked into once when mining on Slush. I don't know if they did it through Slush or what. Ever since then [About a year ago] I no longer left factory password on there.

I would be more concerned with your network security; most routers default to almost 0 security ( as this will be slightly faster and most consumers only care about speed. )

Anyone know what the best running temp for the chips would be to have lowest HW errors ?

I don't think it's temp related. It is frequency related from my experience with units from 3 different batches.

I had my S7 port forwarded and I can't connect to it anymore, does it mean someone must have changed the password to it ??
How can I retrive it's password ?

Factory reset with a paper clip.
