This is slowly turning in to a trainwreck.

September came and went, we are almost halfway october, most customers still seem to be waiting. Hosted miners were reportedly running at only a tiny fraction of their hashrate, and are not running at all now. Alarming levels of DOA. One customer had 5 out of his 6 jupiters catch fire (!).  Software and firmware clearly not ready for primetime.

I really enjoyed following orama's "behind the scene's" reporting (seriously, they should have made a full length documentary, I would have paid for watching it),  I wont fault KnC for lack of trying, and of course, we have seen much worse execution, but I think we can safely say KnC's schedule was once again way too optimistic and they started shipping too soon. These problems could have been avoided.  

Not sure how or when this one will end, but Im already looking forward to seeing the next trainwreck unfold with hashfast.

So anyway,

How many rigs are going out today?

Is everyone still confident that they will ALL be delivered (to the courier) by Tuesday?

At what point will the confidence begin to waver?



- Only KNC knows, not enough for sure
- Absolutely not, they'll be done shipping batch #1 towards the end of the month (hopefully, not very confident on that)
- For me was like 2 weeks ago, but to late to request refund

Thing is, no matter how late they are, all customers agreed that KNC can ship even 100 years late while you're not entitled to request refunds for orders they claimed to be sent for completion at the manufacturing facility!

"The delivery date is provided for information purposes only and shall not be binding on KnCMiner. The Purchaser is not entitled to refuse acceptance of the Products, withdraw, cancel or revoke the order or make claims for compensation due to any delayed delivery."

did you set the SSH SETTING? ie I think you need something like putty to see it remote

Hi all,

just a quick quest to every one who already have a miner at hand.

I've noticed quite high system load (see uptime(1) output):

Code:
root@XXXXXXX:~# uptime
 07:35:10 up 16:06,  load average: 1.92, 1.93, 1.94

looking at top(1) output is clear that the load is not due to some
cpu hogs hidden somewhere. the process that use more cpu is cgminer
with rate varying from 4% to 12%

Then I think that the hi-load is due to processes spending time waiting for some kind of
I/O. After a bit of searching I think I found the culprit:

Code:
PID USER       VSZ STAT COMMAND
  58 root         0 DW   [spi1]

this process spent a lot of his time in D/DW states. from ps(1) man pages:

D    uninterruptible sleep (usually IO)
W    paging (not valid since the 2.6.xx kernel)

Does this description apply to your miners too ?

someone please find out how many miners do they produce and ship in one day; then, we each wouldn't be so blind as to the future.

also as a side note ..i'd just get a cheap wireless router and do it that way..myself charter has wireless on their cable modem was easier just to get a dlink  wireless router and go that route some...charter was a pain to set the wireless from their cable modem box

again just saying ...told charter to just d/c the wireless option from the cable modem and just used my box much easier with the install cd etc

not sure if it applies but just a thought (they still charge me $10 a month for the wireless by the by ) so be it for 19.95 for a netlink wireless router 915 version I think it was well worth not having the hassle of calling them and doing ip stuff thru them

You have to have your machine on the same IP range as the Jupiter to be able to login to it.

Also make sure your browser doesn't have a setup for a proxy server in settings, otherwise you won't be able to connect to a web server on the inside of your network.

This is unrelated to KnC miners, it's just some things you should know about networking.

a) Find out if your local computer (I assume the only people asking questions here are using Windows systems) has configured
  a static IP address or receives the IP address via DHCP.
  Very stupid (but working for LAN, not WiFi) way for anyone who has no idea what I am talking about:
  Note the IP address of your computer by running ipconfig (Windows) or ifconfig (rest).
  You will see at least (!) 2 IP addresses, just ignore the famous 127.0.0.1 on a lo* interface.
  If you see multiple IPs, note down all.
  Remove the ethernet/network cable(s) from your computer.
  Start your computer again. If your computer still has the same IP address(es), you have assigned static IPs in your system.
  Probably someone else did this. If you see now an IP address starting with 169.254 your computer uses DHCP to get an IP
  address. (More info about this: http://en.wikipedia.org/wiki/Zero-configuration_networking )
  More complicated but more elegant way to find out whether you have static or DHCP:
  Go to the network configuration (I did not use windows for quite some time, don't know how to explain this step by step)
  and check if your IP interface (cable or WiFi) uses a fixed/static entry or there is something activated called DHCP.

  If your system has static IPs, there is a good chance that you do not have a DHCP server in your setup.
  That's really a problem for you now. There are solutions, but they need additional hardware or more tricks.
  Please remember: Even a static (default) IP address on the KnC miner will not help you. The KnC miner does not have
  Internet access via that IP address!


b) Some (mainly cable) WiFi routers that also have ethernet ports do not allow access from WiFi to ethernet ports.
  Try to attach your computer via an ethernet cable and repeat the stepts to find the IP address of the KnC box.
  When you have such a setup and also have access to the cable router (which you normally do not have, blame the cable
  operators), you might look for some security settings that deny/disable WiFi to ethernet access.

c) Some DHCP installations only allow a limited (often as low as 3 or 5) number of clients (computers, network devices).
  When you have multiple (wireless connections from phones, iPad etc!) devices already in your setup, try to turn off
  one of them, wait some time (this can be 10 minutes) and start the KnC miner again. Repeat the steps to find the KnC IP.

d) Some routers/switches have a security feature called port privacy. This means, that every device on your LAN can
  only talk to the Internet but not to any other device on your local LAN. It's unlikely that a home network setup has
  this feature enabled, but it can be. This feature can also be enabled on WiFi networks.
  Again: Without access (and not just read only) to the router/switches, you can not get the KnC working without additional
  hardware or lots of tricks.

e) Your local computer might have a network firewall configuration that prevents access to the KnC. It's pretty unlikely that someone
  configured such a firewall rule, but it is possible.

Larger heatsink: I notice that some have high temperatures on their units. Can we work on trying to get the lowest temperatures possible? Someone on kncminer forum suggested reapplying thermal paste so that it is not too thick and not too thin. What about a larger heatsink, can we get one that goes over the whole chip? What are the dimensions of the chip? and what is the best thermal paste for this chip?

The point is that with lower temperatures, you get a much higher hashrate and less errors, i think. I think the temperature thing is the main thing that affects the hashrate.

sure lowering working temperature will be beneficial, but it seems to me that there's room for improvement also in the SW department.

I'd love if O'rama could inform us about KnC's position regarding ckolivas working on cgminer implementation, and about ETA for source code release.
