[demonmaestro]

are you positive its the miner?

[Searing]

ok, so I can see the ip address on wireshark, dos ipconfig, and in adapter settings... but when plugged into the browser...nada


ill donate my first btc to the genius who fixes it

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

(no chance at the BTC i'm clueless just throwing it out there)

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.

Thanks!
Maybe I should offer remote support for network problems.  
Earn some BTC by working instead of mining.

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.

is there a more extreme heat sink arrangement to improve your miner chip heat or is the arctic one that knc has is best in class?



thinking with the temp check in .94 that maybe if you saw one of the chips was really hot you could swap it out with something more
extreme then the arctic i30 heatsink provided


but alas I know nothing about this not even if it makes sense with these devices

Be careful with such an advice. You need to know a little bit about networking etc. or you might fail.
Just be sure to know:

What installation do you have now?
Specially with (TV) cable Internet access you might be in trouble:

Do you really have a cable MODEM or do you have a cable ROUTER?
You need access informations (like username/password) and many cable providers do not hand out these.
Even when you just have a cable MODEM, you must buy a WiFi router that works with this modem.
Same is true for *DSL.

have a static ip but also did this when I had dyn ip


Same is true for *DSL.

have a cablevision box modem  has a 3 way splitter before going to the modem box ..one to tv as well ...

anyway the modem had built in wireless from charter wireless...just d/c the wireless from charter and simply put my own wireless router up think it is a 915 version etc

works fine...the wireless modem version I had provided with charter they as you say would not tell me anything

so screw it just put my own wireless router up and as fire as wired connections also goes thru that as well

works fine password protected all that


and don't really use the static ip address just the default...unsure why I have such prob cause it is like only $15 bucks more should put up a www page etc again

anywhoo.....just saying got tired of calling charter when they had issues and such

been that way for about 9 months now ..mostly I do stuff with computers using the hard wired on my home network also

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 ?

Checked my 3 Jupiters PID 58 (spi1) sits pretty constant at 1%, cgminer sits solid on 15%

uptime ?
ps | grep  spi ?


edit: I'm asking for the above output command because having a such high system load (~1.9) on a box with only one cpu means that your system is overloaded almost by a factor of 2.
        uptime show sys avg load  average for the past 1, 5, and 15 minute in regard to both the CPU and IO.
