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. Most of use really don't NEED to access our home network while out of the house. Some guys are just so geeked out they have to have access to their home network and files, really for no reason but just to have the access. The best solution is to not have any of your systems facing the public internet. Block ALL your devices/systems. Hackers can get through a simple print server if they wanted to. Having Teamviewer running all the time and other remote software is just silly. "But then I can't support my friends or help my grandmother out". Then teach them how to run Teamviewer or whatever program when needed and then teach them how to turn it off. I have been hacked many years ago and have decided to just remove the possibility of it ever happening. Port scanners, sniffers, tracers are all out there. Just have to be careful. |

I dont understand why they are changing it so much ? Are they keeping the good chips for them selves and then just selling off all the poorly binned chips to us ?
Why not just have made it a 4TH machine from the start and not have it so highly strung. Users can OC just like before.
I doubt that very seriously. It's possible [after assembly] they keep rigs that meet certain parameters. If I owned BITMAIN, I would keep rigs that met certain parameters as well. Wouldn't you? Does this mean all the rest are trash? No... I prefer the batches with more strings that results in better power efficiency rather than the 4.0 TH rig with fewer strings and less power efficiency. I know it says batch 6 is the same .25 watts per GH/s. However, I have to see it to believe it. Just wait until the after-market on these. You can't just say "S7 for sale". You'll need to indicate batch, GH, chips, board version, power consumption, and whatever other specs all these different ones have. A warranty and fix nightmare too when communicating with Bitmain. |

I've fixed this before, but forgot what I've done. Can't remember at all. All dashes on the first row, and then sometimes a few X's on the second row. Sometimes starts hashing around 300-400G, but never above. Tried another PSU. This is my fathers rig, so I haven't asked him to try another controller. I'm guessing controller, hash board, or possibly a cable, but I doubt it is a cable. Any guesses? I just have remote access to it right now, but can ask my Dad to try a few things.  First thing i would do is turn the controller 180 degree and effectively swap the blade. If its now the bottom blade (on the webgui) thats dead, then you know its not the controller. Assuming he tried a power cycle already. I've re-flashed from the SD card and also updated firmware. Done all the "software" related procedures so far. I think it is the controller, but just a guess right now. I'll ask him to try that. The data cables are cheap and do fall apart easily. Then i guess software side you can't shut it off for 20 seconds, with PSU unplugged and then replug it. That usually solve minor issues like a couples of X. But a blade line full of X, not so sure. Still worth a try. I have indicated in the original post that another PSU was tried, hence it has been power cycled a few times. You actually cannot rotate that beagle-bone board 180 degrees. The Ethernet square drops down into that green board so when you turn the beagle-bone board the Ethernet jack hits the circuit board below since there is no hole/cutout there for it. Yes, miner has been power cycled several times and a BLAH. |

"For sure my wife would not let me keep the S7 with that annoying loud howling sound so I had to come up with a solution."
Unless you go watercooled the S7 is not a good idea for home miners, imo. Seriously, what are you guys thinking with your homemade tubes and extensions, they are a serious fire hazard. Let alone the noise pollution.
The extreme heat these monsters are releasing have marked a red line for me. The chance something is burning or melting, as demonstrated with pictures in other threads, is warning sign enough that home mining has reached a limit. And 1200 watt PSUs, do they even last for more than a year 24/7? They are also damn expensive.
Designwise, I don't like the entire single heatsinks on the back of the S7- many have reported them to be falling off. Back in the days of gpu mining you were better off with an AMD 5870 than 5970 too. It was just too much of a hassle to get them cooled and running smoothly. The 5970s often died prematurely, no wonder.
Until something has improved, the S5s are probably as high as I will go until the (final) end of home mining in August 2016.
I'm probably in the same boat. I find it hard to realize people are running these in a home. The noise alone would prohibit to run S7's in an apartment/condo at least in my state (NJ). I'd have my neighbors banging on the door at 10pm. Even after replacing my jet blasters (original S5 fans) with quieter fans I still hear that hummmmmmm throughout my house, regardless of which room I'm in. I do live in ranch style house, which is not a good scenario since internal walls do not have insulation. I did insulate with noise dampening insulation on the cheap. All my S5's are in one room with a single window air conditioner. Even when it is almost 50 degrees out (at night) and 60 degrees (in day) the S5 temps will increase to over 60-62, which I don't like to do. I do admit, if the jet blasters were installed I wouldn't need worry at all. I have to give congrats to the new guys who are running these S7's in their homes. I would imagine some really creative options with trying to suppress the noise. Eventually when temps go down to 40F and below consistently I won't need to bother with the temps at all until the spring, by which time home mining for me will be over. Kind of perfect timing really. I did always want to get some 4-5 inch air duct hose and expel all the heat right out the window, but could never figure out how to build it. Don't want to invest another $1 into that setup, so all choices of changing stuff around is not in the cards. Good luck. At almost 1300 watts I think I'm done chasing the mining train. I may have mentioned it before, but most home outlets let you pull about 1200-1300 watts for the entire room (circuit). That means you're asking your ancient home wiring to pull 100% for 24/7 mining. Fires are a real possibility once you get in this range. Imagine all the 17 yr old kids that have a few BTC, order a S7, and plug it into their mom's basement unknowingly overloading the circuit like a Christmas tree with too many lights. Spark, spark, and two huge fans to kick the flame up. Now you're looking at a home burning down and possible lawsuits, though with BM being in China a successful suit is unlikely. I'd never run something like these S7's in my home UNLESS proper wiring gauge and sufficient volts/amps. If you have a family and children at home I would be thinking about their safety before heating up electric lines in the walls and heating up that junction box. 1000+ watt heaters running 24/7 should take special consideration. Just be safe and good luck!! |

Make sure the the user the process is running under has permissions to delete files that the update process is targeting under that home directory. I had the issue with Minera once on Ubuntu.
in some cases just using sudo to start the process i question will get it the correct permission for file manipulations.
It was the typical permissions issue. The included permissionsfix script as it says is for "most" linux distro's, just not on my CentOS. Stupid me for not even viewing the two liner. Just in case the auto-updater runs that, I changed it to reflect my settings. Once did that, good. Still having the issue? If so, we have to make sure the web user (usually www-data or httpd) need to be the group. This is usually fixed by running: sudo chown - R deligus:www-data /home/deligus/public_html/* Thanks. Got the update working ok. I'm always forgetting my apache user is not www-data like most. I tried also changing the layout, it changes visually for a few seconds but bounces back to original. Made sure my user_data is writeable. I did clear cookies using the supplied button. Before I start making more permission changes, ideas on that? Chrome and IE, same results. |

Older versions had more issues on Windows with file permissions which would cause the deletion of files to fail. This is also the case when the application is installed in Program Files. If you still encounter such an issue you have to run the process with administrative privileges.
This is on a linux VPS. Not Windows. Running CentOS/Apache. Checked owner/group and looks good. I'll fiddle and see. |

Nice update does now show Ghash pool but the stats are 0 except for number of workers and url. "0 KH/s user hashrate (1 day) 0 KH/s user hashrate (1 hour) 0 KH/s user hashrate (15 minutes) 1 workers https://cex.iourl" I've had trouble performing the auto-update. Always had to install manually. Keeps telling .17 is installed and wants to update to .28. If I go back and save settings again it will ask me to update again. This is what it says on the green terminal. I don't mind manually updating, but figured I'd try to get the auto-updater to work if possible.

Anyone use duct hose to expel the heat from multiple S1-S2-S4-S5-S7 miners out a window?
Looking for pictures/ideas. I know there must be someone that has done it.
suck better than blow ? Actually thinking about the same thing and will be heading to lowes tomorrow afternoon. I'll post an update when I get started. This is what I'm thinking. Lining up all the Sx's in a row, side by side and just cut a hole in the side of the duct host and put the miner output right in there. With a push from a small fan it should direct all the air flow right out or where I want it. Sorry for the terrible representation. Basically just need one long hose and some cheap thermal tape to close the gaps. Don't really care what it looks like.  I think you might want to position the fan directly adjacent to the window. As your diagram current shows, if there is any kind of blockage at the window, the FAN st the end of the duct will be "pushing" against the miner's exhaust. You really want the fan to "suck" the warm air out of the duct, rather than pushing cooler air into it. Where the fan is currently shown, you could close it off, so that the air would have to flow through the miners to get exhausted. Good suggestion. Have yet to try it, but good idea. A good enough fan to create some air pressure sucking out is good for hotter days. Colder days can just reverse and get some heat inside. |

I've had PayPricks lock my account years ago for something I sold and then the buyer said he never got it so they dipped right into my checking account and took the money. I fought it a few times and never won. I had to close my checking account because of them. A pain in the neck if your checking account is attached to anything. Never used paypal since then. Rarely anyone reads the TOS, but apparently they can take money right out of your accounts. I also switched banks too, since the bank just let it happen without notice. One of these days I want off the grid completely. And not because I'm doing anything illegal. I want to experience true freedom and privacy. Living in America you can't get that. Sounds odd, but it is true.

You have a broken miner.
Is it just me, or does it seems like the S7's are one of the most problematic Bitmain products ever ?  It only seems to you. 3 broken blades from 99 is not to much. This situation arose for me from one PSU and two times. I have using this setup. 1 x Corsair RM 850 with controller and 1 board Corsair RM1000 with another 2 boards. Corsair RM850 turned itself out and another 2 boards are powered for some hours. If I restarted miner from PSU switches, came from miner hot air and the smell of burnt. I put in there the other miner, with the same PSU-s, and after day was the same with 1 board with another miner. Always the blade(s), which was powered with RM1000 and after that, when RM850 Switch off for some mysterious reason. This RM850 works for me today with 3x Antminer S5 blades water cooled , so perhaps it is not the fault of the PSU He bears the load about 850-885 W However, the conclusion is, use only 1 PSU per miner.I am running my S7 with the RM 1000 and RM 850. The only problem I have is I notice the 850 felt warm and did not see the fan running as both fans only turn on when needed so they are hard to know if the fans are working or not. I went ahead and placed a fan to blow air thru it and it's much cooler now. But they have been running the miner fine for going on a couple weeks+ now. I run all of mine with three rm1000 for two s7. You probably have the 850 on one hash board and the 1000 on the other two. The 850 will only be pulling 400watts so the fan won't spin. The 1000 fan will spin because it is pulling 800 watts. For me all three rm1000 fans spin because they are all pulling 800 watts. I did have a problem where one of the rm1000 did not switch on even with the jumper. Caused the miner to think that two blades were partially on but only hashed at 1.5th. Sometimes the controller lies. I would think that with no power to two boards that only one set of chips would show up. Not the case. I put a spare rm1000 in place of it and it worked fine after that. I had to rma the rm1000. They sent me a brand new one. They have 5 year warranty. Ax860 ax series has a seven year warranty. I did get four bitmain 1600 watt psu's so they would fit in a smaller rack. They have been running fine since I got them. If you read some history the RM series PSU's were faulty. Or at least a huge batch of them. This is why Corsair replaced all my RM1000's with HX1000's for free. If I can remember you needed to look/view the PSU serial number to make sure it wasn't a "defective" model. At least a place to start. This is why in the end I'm using Seasonic PSU's. Still using the HXi's, which are made by Seasonic. Good luck. |

How many people feel the need to post their annual salary on a bitcoin enthusiasts' message board? Something to prove, maybe? DMWard is one of the more chill guys I've dealt with on here. Have you considered trying Kegel exercises? I hear it helps with stress.  Ditto on that one. Someone that makes $240k/year and capitalizes OH MY GOSH because of $700, in my opinion is what we call "a cheap bastard". REMOVED |

Someone woke up on the wrong side of the bed. What I said was opinion - I could never justify it. I clicked on the link thinking it'd be ~$300 USD. It wasn't. I was surprised.
Enjoy your remote power switch. Oh, and just to make matters worse, you can do the same thing with an Arduino and about $30 worth of parts AND operate it with your cell phone.
Diff'rent Strokes for Diff'rent folks.
Then why the hell could you not give your opinion on how to do it more affordably in a way that does not mock someone for the feature they seek to have? No, you decided to put a "laughing" face in the forum to mock me with no advice given at all of a cheaper way to do it. Instead, you decide to be an asshole on top of that with these stupid ass short video comments. Why such an arss? Also, you are talking about getting some kind of circuit board or some shit and add $30 in parts onto that? How much for the Arduino to go along with the $30 worth of parts? What else is involved with connecting it to the PDU? I also prefer to control only the PSU I want to control that is connected to the PDU. My father uses this: http://www.digital-loggers.com/220.htmlAnd I use the smaller "home" version to power cycle a couple servers I have. They become pretty powerful due to their scripting capabilities. |

Hi,
I'm trying to get a replacement fan for my S7. Can anyone advise me on specs? Can i look for 5000 rpm casefan for example?
Thanks for your help.
I have over 10 brand new S5/S7 fans still in wrap. I live in the US and could ship USPS. PM and make an offer. Always good to have replacement fans. Mike |
