I wish I was in France. I would purposely win an auction on one of them and pick up locally (in person) just so I could personally beat his ass to a pulp!

I have downloaded OS X Server for one of my Mac Mini's and one of my MacBook Pro's I'm using now. I have several domains through 1and1.com. The domain names are the same; just different suffix's; et al, .us .org .com etc...
1) Install OSX server only on actual server (Mini) computer. Don't install it on portable notebook computers, it severely reduces performance and battery life. 2) With a simple cable modem + Airport Extreme you emphatically don't need a separate firewall, the trivial one already inside the base station is completely sufficient 3) Forget about registering and configuring domains for now, just configure and use "Back To My Mac" service until you have sufficient understanding of public vs. private IP addresses and Network Address Translation and port mapping 4) For now use the OSX server as a normal house computer that is on 24*7, download the server documentation from Apple and skim it (don't read thoroughly). You'll just need to roughly remember what kind of information is available in the Apple references. Many well-meaning advice givers on the forum give complete bullshit information with respect to Apple technologies and you'll need to be able to quickly sanity-check it with the actual references what is true. 5) 1&1 has a proprietary DNS manager web panel that is rather self documenting once you really understand the networking basics in (3) and (4) 6) obtain the actual precise information about your ISP business account settings: is it single IP or block of several consecutive IPs, is it just IPv4 or dual IPv4 & IPv6. Don't post the uncensored details here, don't post your real domain names here, use placeholder names and numerical values. This forum is full of sharks that will own your network as soon as you disclose sufficient information because everyone knows that you are just a beginner setting up your first network. 7) Create a separate thread in Technical Support with a meaningful title e.g. Creating remote-accessible mining farm using Apple technologies. We'll help you more there. Thank you very much, 2112!!! Very appreciated. Sounds like I just need to disable the server I created on my MacBook Pro. I already had Server installed on it. I recently installed Server on the Mac Mini but never took the time to learn it. I'm starting to learn now because I'm about to get back on the road playing poker and training telephone technicians to use their meter for identifying and locating faults on the local telephone loop. I'll stick to Back to My Mac like you said of the moment until I learn more. I will also consider opening a technical support thread for Creating remote-accessible farm with Apple Technologies. I have to get some sleep now. I've been up all night! I have not mentioned my domains here in forums or PM's. I'm cautious in that respect. Going to take a nap. I'll be back later. Thanks again for taking time out of your day to respond with helpful advise and information. EDIT: OS X Server officially uninstalled from My MacBookPro |

I'm wanting to set up my network to be able to access my rigs while I'm away from home. I have a static IP [not dynamic] assigned by my ISP. I have my home network set up for DHCP and NAT. I have assigned an IP address for each rig in DHCP.
What is your router/firewall running ? I use a CentOS distro as my gateway/firewall with OpenVPN installed to allow me access into my home network when I'm out. Once I'm VPN'd in, I have access to all the systems on my private LAN. Check out http://www.clearfoundation.com/ for more details. Basically I have my network configured as ISP Router <-> DMZ-Host / Lan Gateway / Firewall <-> Internal Lan Segment ClearOS has dynamic DNS services so whenever my IP changes, I can just use the DNS name I've selected to access my gateway. I have no idea what firewall my Airport Extreme Base Station uses. It has one and it is on. It does not tell me the name of the firewall. EDIT: After looking at Apples website, it is a firewall they developed and not from a 3rd party. I will check out the link you provided after I make this post. Many options have been presented to me by several people; even using Team Viewer. I'm not sure which would be best for me to use at my present location. I will be moving to another location in the 4th Quarter of this year. So, keep that in mind for ease of transferability. Something tells me maybe I should set up my own server with a Mac Mini [As I mentioned above]. I'm just not sure which to do from so many suggestions. What would the advantages and disadvantages be of setting up my own server with a Mac Mini? |

I presume you currently have a cable modem in front of your Apple Airport Extreme. When you move also use a modem for the ISP access. If the new ISP forces you to use a "residential gateway" learn how to configure it to "bridge mode" and continue using Apple-only networking. Avoid "double-NAT" and other hacky configurations, there is a frightening amount of misinformation on various support and discussion boards.
Sorry for the delay. I fell asleep after a long last 3 to 4 days. Yes, I currently have a business account with static IP through Charter Communications [A cable provider]. You said, When you move, also use a modem for the ISP access." That's what I was thinking about when moving. I have downloaded OS X Server for one of my Mac Mini's and one of my MacBook Pro's I'm using now. I have several domains through 1and1.com. The domain names are the same; just different suffix's; et al, .us .org .com etc... [Pardon my ignorance] I'm presently looking into what I have to do to register a host name per these instructions for OS X Server provided below. To allow users to access the server by using its host name on the Internet, you must register the server’s host name. Obtain an Internet domain name, such as example.com. If you don’t already have a domain name, you can purchase one from a public domain name registrar. For information about domain name registrars, search the web. Register a unique host name for this server, such as server.example.com, with your domain name registrar. If your organization has a computer support group, request a host name from them. Otherwise, work with the domain name registrar where you obtained your domain name to assign a host name. Have a DNS hosting service add records for this server to its DNS servers. If your organization has a computer support group, ask if they host DNS servers. Otherwise, your DNS registrar might provide DNS hosting service, or you can search the web for a provider. Maybe I'm going about this all wrong and I should not set up a server at the house? I'm assuming the server will allow me to see the screen on the Mac Mini; which in turn would allow me to have access to my rigs? |

I'm wanting to set up my network to be able to access my rigs while I'm away from home.
From the rest of your post I can tell that you don't understand what you are doing with your network. If you keep opening ports the end result will be that the remote hackers will have better control of your network than you. With your level of knowledge the only way to do it is to keep one Mac permanently at home and configure your Airport to allow only Apple Remote Desktop to your at-home Mac. Alternatively you could use "Get To My Mac" service from Apple. After that you can buy the Mac OSX Server upgrade from Apple (less than $20) and set up your own VPN and other services that are described in the OSX Server documentation. Reading the OSX Server docs will also help you to learn and understand the networking basics, both general IP and the Apple specifics (like afp:// not aft://). No matter what you do you will have to have a permanent (or nearly permanent) computer that monitors your home farm over the LAN. If you don't yet have a spare Mac at home than buying a Mac Mini and installing a server upgrade on it is the best way to spend time and money. Have fun, just don't become another basket case Mac user with home network owned by hackers. Edit: Ha, ha! Our posts were seconds apart! Should I just set up one of my Mac Mini's to stay on all the time and access it via "Back to My Mac" to have access to my rigs?
Listen to your own internal voice! I'm setting up one of my Mac Mini's to gain access to my rigs when I'm away. I'm going to use OS X Server to connect to the Mac Mini and the rigs in turn. Thank you for your input. I was talking to you and two others at the same time. I was thinking about sing "Back to my Mack" to gain access. Seems to be a lot involved in that with port mapping. So, I'm doing my homework on Mac OS X Server. |

You need to explain your network topology more.
I would think that the ip address would be assigned to your router not your computer.
It is assigned to my router. Sorry if I didn't explain well enough. Currently what is running the NAT to assign IP's to your network devices? Your router or are you already running ICS?
My Airport Base Station Extreme tells me it is presently set up for DHCP and NAT. I manually assigned my rigs an IP address in DHCP. I do not use Windows for ICS. I have all Mac devices other than my mining rigs. Normally with a router managed network you would have to setup the port mapping on the router, you won't need ICS
So yeah, more info needed.
Yes, I'm looking at the window for port mapping but have no clue what service to enter in under port mapping. I listed those services in my previous post. Here is an example of the drop down window for port mapping:  On another note I wouldn't recommend putting a money making machine directly accessible on the internet even if you are obfuscating the port used.
You could restrict access to the ports to certain IP addresses, but by far the best way would be to setup a VPN, especially as you are planning on having a large farm.
Then once you VPN in you are on your network as a local node and can access everything as if you were right there!
Yes, I would agree about the VPN. I have no idea how to set one up. Should I focus my energy on doing that instead of port mapping right now? |

Hi everyone,
I'm wanting to set up my network to be able to access my rigs while I'm away from home. I have a static IP [not dynamic] assigned by my ISP. I have my home network set up for DHCP and NAT. I have assigned an IP address for each rig in DHCP.
I'm assuming I would set up "port mapping" to connect to my rigs. However, I'm not sure under what service in port mapping I should set up my rigs for. Here are the services available in settings for port mapping:
Personal File Sharing
Windows Sharing
Personal Web Sharing
Remote Login - SSH
FTP Access
Apple Remote Desktop
Screen Sharing - VNC
Windows Remote Desktop
Remote Apple Events
Printer Sharing
POP Mail
POP Mail with SSL
IMAP Mail
IMAP Mail with SSL
SMTP Mail
QuickTime Streaming Server
XMPP - Jabber
iChat File Transfer Proxy
OS X Server VPN - ISAKMP/IKE
OS X Server VPN - L2TP
OS X Server VPN - PPTP
OS X Server VPN - NAT Traversal
Remote Server Administration
Lights Out Monitoring
Remote Directory Access
Once I choose a service to port through to the rigs, what do I need to enter in the address bar of my browser in front of the static IP address my ISP gave me? For example: With Personal File Sharing chosen as a service, it is my understanding we enter in aft://then IP address:and port number.
Also, is their anything in particular I need to tell the SP20's to access them remotely?
|

|

I have 4 sp20. One is burned; magic smoke an smell is out from controller board. One with network leds blinking but I can't access and 2 full functional.
I have a tp-link router; all miner use DHCP; the router do not assign an IP address to 3rd miner, only 3 IP, 2 to the functional miners and one for my laptop!
It sounds like TP-Link routers allow you to see the IP address it assigns to devices without the need of an IP scanner application; unlike my Apple Airport Extreme Base Station. This sounds like you definitely need to Skype with support. If they cannot even connect to it through Skype, they will make arrangements for refund, repair, etc... |

Does myminer.io show the rig and it's IP on "Your Miners" page?
If it does show an IP but you are unable to connect, you have a similar issue to what I had.
Download LanScan [or similar application] to scan for IP addresses on your network.
Once you do, you will find out the IP address myminer.io has given you does not even exist. However, you should see a new IP address on the device [At least in LanScan]. Enter that IP address in the browser address bar of your browser. If that isn't it, try another IP Address you see in the LanScan application or similar application until you find it. If you do not find it, do as Spondoolies said.
I use MacBook Pro's [not PC] at my house. LanScan, is an application I downloaded from the Apple App Store. If you have a Mac, I suggest you download that application. It is quite nice and it was free. They have a LanScan Pro that cost money but I did not get it. I didn't even need the Pro version to fix my issue.
You may have had your SP20E for a while and it is only now that this has happened. It is still possible for this to happen if you did not go static IP or you did not assign each rig an IP address [manually] while in DHCP like I did. If you have a power outage and the power comes back on [while using DHCP] it is quite possible your router assigned a new address to that one rig but myminer.io still says it was the previous IP.
My issue with IP addresses came up both times [when I first set up my 15 SP20E's and after a power outage when I did not have an IP manually assigned to each rig yet before the power outage].
Sometimes, after a power outage, I have to go to "Pools" and click "Submit" [Even though all my pool info is entered in]. Because the home page of the miner would say CG Miner was not working or "NA." Once I clicked "Submit" on the pools page [sometimes I clicked 2 or 3 times] the rig would begin mining and CG Miner would be "Running" on the homepage.
I hope this helps!
If it did, Happy Mining!
If not, do as Spondoolies Support suggested with Skype.

When you set back to default settings on the S3 is that by putting 0725 in the voltage?
I'm assuming it is the default. I really don't know for certain on the older S3's before the S3+ came out. I do know that is the default on the S3+ models. I know this because I got two S3's of the last batch (batch 11) with the January, 2015 firmware and they were default at 0725. I went ahead and put my old S3's at 0725 volts. Then shut it down and turn it back on. EDIT: I've been up all night doing taxes. It is 10:20am and I have not had sleep since 2:30pm yesterday. It's night night for me (bed time). |

Running solid for couple days. Pulling 795w (kill a watt) = .5794.
Do these run better, more efficient, if the chips are colder? Say 85c vs 110c.
Not sure if your fan is set to "auto" or not? The reason I say this is because I see your fan speed is at "10." This is a big part of the reason your ASIC's are pretty damn hot on some boards. I prefer "longevity" of the unit versus "working the hard" at high temps. I prefer higher fan speed to keep them cooler. Yes, it is less power efficient if you wish to maintain your present hash rate with a higher fan speed. However, it increases the life of your ASIC's. This is my opinion. If you insist on having a higher hash rate while taking care of your rigs, consider a higher fan speed while sacrificing power efficiency. I clocked one of mine to a similar hash rate as yours but with higher fan speed to show you the temps and power consumption. The present power efficiency at these settings is .63 watts per GH/s. Understood. Thanks for the opinion. Is 100-105c acceptable? I'm balancing fan noise with longevity with hash rate with wattage. In my opinion, it is not acceptable for the longevity of the ASIC's. The fan is there to keep it cool. We need to allow it to do it's job. The "auto" setting for the fan doesn't work quite well at keeping the ASIC's at less than 85c unless your ambient temperature is less than 10 degrees Celsius (50 degrees Fahrenheit). Again, this is my opinion. Others may see this differently than I do. You can ask around if you like at other Spondoolies-tech threads. |

My Kill A Watt meter was defective when determining power consumption of my rigs. In fact, it has burned out completely now and will not work. I got information from another buddy who has a working watt meter and came up with the following results: I HAVE DRAWN THE CONCLUSION IT IS NOT WORTH UNDER-CLOCKING THE S3 or S3+ [At least at present price of bitcoin]. I don't know that it would ever be worth under clocking it? I can see under-clocking to make more power available to add more rigs with a higher hash rate and better power efficiency to your present set up. That's about the only advantage.

I don't have power meter on my own but what did your mate found out on your setup?
I copied only the portion where he mentioned it. Here it is: Anyways, I was running the numbers using some kill-a-watts and when I downclock the S3's to 175Mhz and lower the voltage to 0.68, they seem stable at about 340-360Gh/s but still run about 270watts each. When I run them slightly overclocked at 237.5Mhz, I get around 460-500Gh/s and uses 380watts. So after calculating it (I pay $0.12 per Kwh here in CT) I make an extra %40-50 income per day. The larger SP20's I can run with no electricity costs, so that should be much better. |

By the way, I thought I would share my progress on my new mining closet built downstairs and offer details about the firmware updates and the advantages of getting your rig to the January 09, 2015 update to be able to under clock your S3 to make them more power efficient and to enjoy a much faster interface. I updated 13 S3+'s and 5 S3's with approximately 4 hard resets required during the whole process of updating them all.
I also have older S3's [5 of them]. They too have the most recent firmware upgrade to allow adjustment of the frequency and voltage. They average 370 GH/s at approximately .63 watts per GH/s. I thought I would save space by not posting a screen shot of them as well. Even your old S3's can be upgraded with the most recent firmware. You have to make sure you upgrade the one dated for August first. Then do the october update next and the January 2015 update last. If you try to go out of order, you may brick an old S3. If you get the following screen [screen shot below], do not panic. Just do a hard reset to factory defaults [entering in your pools, etc...] and pick up where you left off in the order of the updates. You may have to reboot once you're finished. If you get that same screen again after reboot [shown below] do not panic. Your old S3 should come back after a reset to factory settings.
Many thanks for sharing your experience dmwardjr, I have updated my 2 S3+ and my 2 S3 today to the newest firmware and copied your settings without any problems! Miners running nice quiet now in my garage and I will have a look at the power consumption tomorrow after 24h running. Have a nice evening (in Germany its 21.14 now)  You're welcome... My Kill A Watt meter burned out on me a couple of days ago. I got a buddy of mine to do the same things with his S3's and he has a Kill A Watt meter. It turns out my reading on my Kill A Watt meter was defective. The rigs are still more efficient at the new settings. They just are not as efficient as I had first anticipated because of a defective meter. That' 2 Kill A Watt meters gone bad on me now.  Anyhow... I'm glad I could be of help. I wasn't sure if all of the firmware updates had to be done in order to get the rigs to work properly. I just heard so many stories of people jumping straight from their present firmware to the most recent with sob stories. So, I thought I would just go up the ladder [in order] and everything worked fine with all 18 S3's [Some of them older S3's and not S3+'s]. I'm absolutely loving the faster interface with these now. |

Thanks for the breakout boards!  These 2880's are loud! This is the man who has it going on right here! Very nice set up you have there, Sir! Are you enjoying the Neptune's? I know you are enjoying these 2880W's and the breakout boards. The breakout boards really make things easier. |

does your fan vent in from the outside or TO the outside....
btw: really nice work!!!
Thanks very much! Still a work in progress. It's sucking the heat out to the outside. That's the most important thing... Getting the heat out; rather than trying to overcome it with AC. I will upgrade this fan from 7,800 CFM to 22,800 CFM when I add another 60 TH/s. A little more has been added to it. 41.4 TH/s that is under clocked to 35.4 TH/s at the moment for better power efficiency. All of the S3's have been upgraded to the latest firmware to under clock by varying the frequency and the voltage [All S3's at 193 MHz and 0625 volts for 380 GH/s to 400 GH/s each]. Those Corsair's will be replaced with 2880W PSU's once I've finished my taxes and made some solder connections on the breakout boards.  |

They want to make someone create an account to even file a complaint. I'm not giving them my damn contact information. I would suggest others be careful doing so as well.
Already have an account. Spend 100$ a month there I can report it but will let SPtech handle this. Sounds like it may be a reputable site then. |
