Topic: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s - page 16. (Read 231002 times)

I suppose we're going to need more info on your datacenter setup to answer that. It can get complicated depending on how your NAT and IP forwarding was set up.

Just so I'm clear, you're trying to connect to the 240.x.x.x address (the public facing IP given to you by the datacenter?), and then access your CoinTerra unit (which is addressed on the 192.168.x.x subnet)? Nothing in between (a firewall, for example), and nothing happens when you try to SSH directly to the 240.x.x.x address?

So I know the IP  address 240.XXX.XX.XXX, and then how do I connect to 192.168.1.XXX? How do I connect to 240.XXX.XX.XXX and point to 192.168.1.XXX??? Please let me know  thanks.

This is essentially what I've done as well and so far it's worked out quite well. Since we've got other servers in our rack, I was able to spin up a Windows 7 VM...cleaned it up, and the only things on it are Chrome, PuTTy, and AVG. I'm behind my company's firewall with an exception for my IP, so I connect up via direct RDP, but I'll probably switch over to an IPSec tunnel soon.

I also use the 'Bitcoin Mining Monitor' Chrome extension set up with my API key from BTCGuild, so I constantly see my current total hashrate. Any fluctuations below the norm and I usually see it, and act on it, pretty quickly.



There are a few ways, but if you're using a Windows-based machine you can use PuTTy, which is a fairly popular SSH and Telnet tool. Assuming your unit is configured to allow SSH (which I think it is by default) and you know the IP of your CoinTerra unit, select to connect to it via SSH / port 22. I believe the default login info to the unit is: root / cointerra
Once in, just type reboot to restart the device.

Try logging in via SSH and issuing a reboot command from the command prompt, it usually gets the dead core up for me so you don't have to drive 30 minutes.

Another possibility is just using simple timers. If it always fails after 2-3 days, then perhaps just have a timer to turn it off for 5 minutes once every 24 hours? My Dad has had flaky hardware that would screw up in a similar manner and this automatic scheduled power cycle once a day resolved his problems and kept it responsive. He used just a basic wall outlet timer he got at Home Depot for cheap, nothing fancy just consumer grade stuff. Just keep in mind that whatever timer you get will need to handle all the amps these pull. I'm not sure also on if you'd have to power cycle both PSUs at the same time or in quick succession - I only just got mine and haven't experimented with the "3 second window" thing on powerup yet.

I do this myself personally - I run a basic box onsite that I connect to remotely from Teamviewer to manage multiple CTA and Antminer units. I don't know of a way to connect to the WebUI systems they use for management outside of the LAN, so I just use Teamviewer to get behind the LAN and then log in from there. Right now I've got one unit running on Eligius so I can just have a bookmark for that address and check it frequently and I've got another on GHASH that should send me an email if there's a hashrate drop.

I am not sure how handly the Windows box would be because if you can't connect to the Terraminers from outside the datacenter(via Web, SSH), it would be almost the same from the Windows machine inside the data center as well. If there are a bunch of Terraminers, it would be nice to monitor them all off of a Windows box though to keep them all behind a firewall.

Thanks, that would come in handy. Now I have to see how I would use it at the Datacenter. I have to ask the employee to change the original to this. What you think of putting a Windows Desktop PC in the datacenter and remotely connect to it to monitor the Teraminers?

No, its a remote reboot or rather power cycle hardware so that you can power cycle your box via the internet. Here is an example:

You will need a cat 5 into the PDU itself with IP address to make it work though. VERY VERY HANDY!!

Are you talking about a power distribution unit (PDU)? Can you give me more detail how to use this to my needs? I never heard of this product, do yo you have any reccomendations, brand? thanks.

Not to defend CT, but get a remote controlled PDU. Doesnt your DC offer that?

Sadly all the preorders after March is going to lose significant money with 1th 880w boxes at $4000 already with a <7 day delivery, and price will continue to drop as china pump them out like no tomorrow.

I am baffled by the fact their website state the 400gh 400w $1600 cards are sold out with a June delivery. Who in their right mind would preordered those? I have a feeling none bought them and it was cancelled, and cointerra is just blowing hot air.

Terrible situation all around, I hope those who were lucky enough to get theirs in feb are able to ROI.

Looks like the chinese are the ones who ended up able to make and deliver stable miners on time and without completely ripping off the buyers on price - both antminer and the new 1th box are all from mainland china. Who would have thought.....

Cointerra is totally ignoring me for an RMA. They will not respond to my emails and conversations on Cointerra forum. DO NOT BUY FROM THEM if you expect good customer service they will not honer it. They're one of the most terrible company. Their machine isn't even stable, I leave it at the datacenter and CTA 0 always die during a 2-3 day hashing, so I have to drive 30 minute there every 3 days to power cycle it. I will never ever buy from cointerra again.  

I would hit up the forum moderator on cointerra web site. He helped me a ton and is a fantastic guy.

What exactly happens?

Do you get 2 green leds on each power supply?
Are the fans running?
Does the CNTR1 led go orange for 10 seconds or so and then turn off?
Can you access the web page?

Ok, machine was working great for about 1 day, hashing 1.6-1.8THs, then it just went offline and I cant get it back. Saw other people had the same problem on this thread and they said rebooting several times did the trick. I've tried that many times now with no results. Any suggestions? Its almost impossible to get these guys on the phone.

Yep, I've got two in March batch and two in February. My two in February are just shipping out today, and even they aren't going to make much so I recommend if you have April or later batches to probably go for the refund instead, unless you think you can flip them for a profit of course.

Also, Cointerra fucked up my shipping big time. I now have to wait until Tuesday to get it because they shipped it UPS Ground instead of the UPS Next Day Air I paid $250 a unit for. Great. They told me they would "refund me the difference". Doesn't look like they're going reimburse me for the almost $400 (just at current rates) that this will now cost me, even though they damn well should. I think after this I'm done with any sort of preorder bullshit and I'll be sticking to GPU mining and the gear I already have and will only order from companies such as Bitmain who have proven solid.

I'm currently debating whether to trash them all over the forums/internet because this problem I described above is only a small portion of the bullshit I've suffered at the hands of this company. I'm going to wait for now and see if there's any resolution offered to the various problems I'm having with them and their "hosting partner". Oh and I was told 4-5 weeks for refund - you're not alone jjiimm_64. Unfortunately because of the way this industry operates I'm not sure if it's worth the time as I expect they will get their orders filled regardless. Just look at all the idiots still ordering from BFL.

Ok great, thanks.

Not that I've observed. I don't have a power meter specifically on that unit, and guessing from my aggregate load it may have decreased it if anything. Probably better to ask someone with a big farm of them however.  As you can see in that graph, it didn't adversely impact latency at least (DOA rate of 1.2% pretty consistently).
