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

If you are still reading my post: Congratulations!

I think you did an excellent service to the community with this tutorial Tongue
kudos

Thanks!
Maybe I should offer remote support for network problems.  Wink

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.

If you are still reading my post: Congratulations!

do these things default to a 127.0.0.1 address when no DHCP SERVER to assign IP addie???

Sure!  Wink  (please don't beat me, but many people will start to realize that this is a good joke)

Yes there are freshly generated coins entering the wallet the refunds came from. That's not a covert mining farm minting coins to refund. That's your hosted devices up, and running. Hosting is live. The issue is configuring the API to your accounts and that is being sorted now.
...

Thanks for this detailed explanation. It's much better than any information I did receive vie e-mail from KnC.
(But getting some info today about the hosting via e-mail made me calm down as well.)

I assume this is the "wallet" address, or?

http://blockchain.info/de/address/1D5FhoiuLMJJ43BCMGidwvbKWfr71g1vH9

I still did not quite understand the current "setup" - I assume it's something like this:

All customer miners in the hosting facility were configured to the new KnC (or some other?) pool with the above
wallet address. KnC did a semi-manual payout for all customers of 2,5BTC per Saturn and 5BTC per Jupiter.
This static setup will continue to mine until the web-frontend for the customers is ready.
At that point the owners can re-configure their miners with whatever (single  Angry ) pool they want.
When the dust did settle there will be an update for the web frontend that will allow the configuration of a backup
mining pool as well or KnC will perform a manual setup of the backup mining pool  Grin

A short confirmation would make me (and hopefully many others as well) happy  Roll Eyes

Update from a hosting customer:

I just received a 5BTC payment in my configured BTC address. I didn't receive a mail with hosting details and the miner is not online yet (at least I can't see it in my preconfigured pool).

I can confirm a payment of 2,5BTC (Saturn hosting user).

cgminer keep show me accepted by FPGA 21 works, but onlt 0 submitted
it casue only 10% accept on pool

This message shows up for me as well.
Quite often when a new block is started, but only (seldom) under normal operation.

Shortly before a restart of cgminer, those messages run through the cgminer window at 10-20 per second.
But then the cgminer process is restarted (screen session terminated) within seconds.

I don't know if those infos will help you, but I am just a customer and that's all I know from observing
my Saturn miner.

trepex thanks for sharing this info.

Did you disclose your finding with KnC, it could be a useful info for them.

did you notice any an increase in performance ?

Yes, of course I also sent out an e-mail to the KnC support as I am not sure they read all what is
going on here in that forum.

And yes, it looks like the (long term average, more than some hours) peformance did go up slightly.
It's hard to give a real number, but I would assume it to be +5Gh/s. I think it's due to no restarts and no "slow startup performance".
I don't have the impression that the max performance or (short term) medium performance really
did go up.

Update on the 0.93 cgminer restarts (Saturn):

I have the Saturn miner running with Bitminter as primary pool. Minimum difficulty had been
manually set (on the pool web interface) to 128.
 
With this setup, the miner and the pool often switch up to difficulty 256 and back to 128.
 
Today I reconfigured the Bitminter pool for a minimum difficulty of 256.
Since then, I did not see any cgminer restart. cgminer is now running for more than 8h 11h.
In the past the max. I could observe had been 3h.

My hosting place has taken 4 people 2 weeks to setup... and Im not even close to their size. They needed to have started earlier

I know about the complexity. I did run an internet service provider 20 years ago and we later did offer hosting as well.

Today, I would not setup my own hosting facility anymore. Just buy this service (space, AC, power, internet) from a big hosting provider.
You might even buy the 19" racks. Get a "cage" or some dedicated rooms for security reasons.
No problems to scale up and you can scale down. KnC should focus on their special skills and not try to do everything
on their own.

But maybe they just rented hosting space...

I expect some more facts form KnC!

I spoke with them this morning as well - same story. Unfortunately I was told the same thing Monday morning. I'm still hoping that today is the day though.

UPDATE: A copy of those questions has been sent directly to the KnC team via e-mail.

I really do not understand what the problem is and would like to hear the truth:

- Is the hosting area with racks etc. ready?
- Is the aircondition ready (or maybe not needed)?
- Do you have the power supplies (and paper clips Grin = ready?
- Do you have (enough) power in the facility?
- Do you have (redundant) interet uplink there?
- Do you ave the miners at the hosting facility?
- Do you have some people there that can wire up the PSU to the miners, put ethernet cables etc.?

If all are answered yes, why can't you bring up the miners? Use the configs provided by the customers
provided at the KnC order formular.

- Do you have your "Hosting Web Interface" ready?
- Do you have some kind of NAT/mapping for the customers access to their web interface on the miner ready?

I still hope that you only have problems with the last 2 points.

Please update us on your real problems?

Problem report sent to KnC support:

Hello,

my Saturn miner is running with about 7.5% HW errors (0.93). It looks like this is normal / known by KnC.

But my cgminer process also terminates itself from 2x per hour up every 3h. I did not observe any uptime
of cgminer much greater than 3h.

I observed (by pure chance) such a restart life:
Everything did look normal. A new status update in the bottom of cgminer every few seconds.
Suddenly there did show up error messages like

KnC: accepted by FPGA X works, but only Y submitted (where Y=0 or 1 only I think). X was always < 10.

I did not manage to make a screendump fast enough.
Those messages did show up at a rate of 10-20 (?) per second. SO really fast. After a few seconds the
screen session did terminate and the cgminer process was restarted.

KnC answer (vie e-mail) with small comment from me:

Hello Ralph Ralf,

We are aware there have been problems with CGMiner in the latest firmware 0.93. These have been fixed and new firmware 0.94 will be released on our website later this afternoon. Please apply this as soon as it becomes available.

Regards,

Liam

Hello,

I'd expect they have better things to do than adding for certain customers additional pools, etc now.
They said, in the beginning there will be the KnC-pool available, only as far as I can remember.
As soon as the management interface is up&running you can do what ever you want.
I'd hope they will not modify the config file via ssh for each and every hosting customer asking for it as it would delay startup even further.

I can fully understand if KnC can't configure backup pools before they have solved all the other problems with
the hosting, BUT:

- I have not heard anything about the KnC pool yet. After all the current problems (like webinterface having no option
  for a backup pool) I do not have trust in a KnC pool at the moment.
- From another call with KnC I still assume that no one will get ssh access to the hosted miner. In combination with the
  webinterface not offering the config of a backup pool, this is something that KnC must do manually. Sorry!
  The hosting is overpriced for a normal hosting and I assume one reason is that KnC must do additional tasks normally
  not covered in a normal hosting:
  Doing software / firmware updates.
  Configuration of "normal" mining features via SSH as long as the customer available web interface does not allow this.
  Replacing units that caught fire / did explode  Angry  Sorry, I could not resist!

I cannot enter in the "mining" tab from the webui in one of my miners after I manually set up a failover pool in cgminer - everything worked fine until I added a new pool, removed the previous one, and added a third - now when I click on the "mining" tab on the webui I get a blank, white page.

Obvious SSHing the box and configuring cgminer directly still works.

This happened only in ONE miner, the rest are working fine despite of adding a failover pool - nevertheless, for those miners I just added a new pool and enabled failover, on the contrary on the "faulty" miner I did and undid a few changes in the "pool management" in cgminer.

Anyone with the same problem?

Yes, after adding a backup pool within ssh/cgminer, I get an empty (?) page from the web interface on the mining tab.
It's pretty OK for me, as I don't need the web interface for configuring mining pools.

Hello,

I spoke with KnC on the phone again (!) about the hosting.
All DAY1 customers with hosting should have their miner up and running in the hosting center by today (Tuesday).
They will receive an e-mail with the access informations.

I assume this will be just the web-interface. So I already sent them an e-mail yesterday requesting 2 external
pools to be configured (which can only be done via ssh access inside of cgminer).
I don't believe this will be done without a further call, but let's hope for the best.

Hello,

I just observed a "crash" of cgminer life but had been to slow to make a sreendump/capture.
I just wated to check how long cgminer had been running, opened a "screen -r" session. Uptime
had been >2h. My Saturn was hashing at about 270GH. I did not close the window but changed to
my webbrowser. Some minutes later I noticed the cgminer messages to scroll in that window at a
very high speed.
Not the usual
- Accepted ...
- KnC: core ... enabled/disabled
but something like "... only 0/1 shares" (sorry for not remembering the correct message)
at a rate of 10-20 per second.
Just as I wanted to make a capture, the screen session was terminated and some seconds later
a new cgminer started by some scripts.

Did anyone observe this as well?

458  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: October 07, 2013, 05:39:01 PM
No restarts on my Saturn running 0.92 or 0.93. Only reboots were updating firmware and had the miner since Sat.

No restarts of the miner or no restarts of the cgminer process itself?
You only see the cgminer restarts by logging in via SSH I think.
459  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: October 07, 2013, 04:45:05 PM
UPDATED!

Anyone tried to setup ssh public-key authentication by creating a /etc/dropbear/authorized_keys (chmod 600)?
It's not working for me.

Maybe '/etc/dropbear' is the wrong location.
Have a look at /etc/init.d/dropbear, there you can find the ssh config in the form of arguments. (at least it's the default location)

What about '~/.ssh/authorized_keys' ?
btw: chmod 600 for user root or for the user running cgminer ?

If they have not removed key-login from the source, it should work if configured correctly:
https://matt.ucc.asn.au/dropbear/dropbear.html
"Compatible with OpenSSH ~/.ssh/authorized_keys public key authentication"

The directory /etc/dropbear did exist already, so I did assume that's the correct one.
(This works on OpenWRT devices.)

I did not spot any special config directory in the startup script.

I meant "chmod 600 /etc/dropbear/authorized_keys" running as root. I created that file manually (using vi).

Update: '~/.ssh/authorized_keys' works. I did not check if this will be permanent.

Hi,

I hope the miner arrives soon in the USA!

I received my own Saturn miner today in the morning (Germany/Europe) and it is hashing fine  Grin
You should (manually inside ssh/cgminer) configure a backup pool.
I had my setup configured with Bitminter and Slush (bitcoin.cz) as fallback and the fallback pool did receive
some shares already (after 8 hours).
