Thank You Spondoolies.
Great Products and a sense of humor

change your admin/admin password and close port 80 in your router and root/root pass

I have a strange issue happening with my SP20....after running for a 4-6 hours, cgminer will crash, and I will not be able to log into the unit with the usual username/password. The logon screen get stuck on the prompt after I enter the creds and press enter. It never locks me out, or goes to the Unauthorized page, just continues to ask for the username and password. I can ping the device.

The only fix is to remove the SD card, reimage, and reboot (My sp20 doesn't fare so well unless running off an SD card)

Has anyone had a similar problem? This has almost become a daily occurrence, and is very annoying.

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

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.

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?

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?

Take the answer from Spondoolies, but as I understand it, 2.6.14 is more recent than 2.6.7. Hence 2.6.14 has additions over 2.6.7, and not the way you describe.

Sweet, recovery was successful.

What changes does 2.6.7 bring over 2.6.14? Should I just stick to 2.6.14 for now?

Also, is there a firmware changelog somewhere out there for both stable and beta releases?

happy pi day

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.

Thanks for the link, PatMan. That's basically what I did with the class 4 card. Maybe I just didn't wait long enough since the lights never stopped blinking between yellow and green. I have to wait until they stop blinking, I imagine?

I'll go try again shortly using my phone's 64GB Sandisk Ultra SDXC.

Stay safe, man!

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.

At least you are aware to avoid following misinformation from Windows users.

Port mapping would probably actually be the easiest option, which is also why it's one of the worst options - absolutely no security involved.

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.

Thanks for the info, I will think about it!

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!
Listen to your own internal voice!

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?

It is assigned to my router.  Sorry if I didn't explain well enough.


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.


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:




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?

You need to explain your network topology more.

I would think that the ip address would be assigned to your router not your computer.

Currently what is running the NAT to assign IP's to your network devices? Your router or are you already running ICS?

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.

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!
