Not my fault he's incompetent and can't figure out how to release his own client. Nor is it my fault that he decided to premine his own coin.

have a nice traded with  Bigal   10K FC. thanks. you are a good seller.

Onto a new issue. I want to beable to control remotely what pool is selected. Since I have 9 rigs I want to do this programatically. I am very knowledable of VB and linux, but am new to JSON/RPC. I would like to be able to send such a command via the network interface using RPC via VBA.net. From looking at the cgminer source RPC/JSON commands are accepted through the use of port 4028. What would be the simpliest way to send an RPC packet from VBA.net to switch to pool 2 and viceversa switch to pool 0.

Any help would be appreciated. I have exhausted the third party addons for JSON serialization and RPC protocal and have not come accross a viable solution.

Thanks,
Mark

I'm going to give that a try. Have you had to do this too? (ie are you having stability issues?)
The main question here is can I get the Pi to mine reliably without ANY reboots or hangs?

I wanted to chime in on this as I appreciate the project. I am running a modified version of the 12/8 distro, having switched everything from cgminer to bfgminer 2.10.2. I had a 256mb pi that I switched to a 512mb thinking all usb problems would be fixed. On both versions same day comm error problems solved with doing a rpi-update. I am stock on the november firmware is I also have the bug that rpi-update will not upgrade more then once. Been running 2 days without a reboot, but I except a reboot once every 3-4 days is going to have the be the accepted norm on a RPi. I have not had watchdog reboot the system yet automatically, but will watch for it.

sudo rm -rf /root/.rpi-firmware

2.9.7 takes about 2 hours to cause a system reboot. Digging though /var/log/messages shows this:

2.10.2 is now what I'm running (I kept on switching between the two to see which one would result in the most stable results...so far cgminer bfgminer (both version) has caused issues.

The thread starter also reported having COM errors with his BFL units with cgminer (latest build).

vm.min_free_kbytes = 8192

smsc95xx.turbo_mode=N

sigh... really.... for my miss bid....  :/ dam it

so did i win??

I'm not sure if this is relevant but could someone else run that command and tell me what firmware version you've got?

I'm running rpi-update right now..taking a long ass time..read somewhere that it could take up to 20 min..

Maybe that will fix this issue..

Not seen a mention of these boards: http://www.hardkernel.com

The only bad thing about these things is that the site doesn't accept BTC. Otherwise, they sound fantastic: 2GB of RAM and 6 USB connectors kind of sold it for me. And it's using the Samsung Exynos SOC, so it should have plenty of CPU (and RAM) left over for other stuff. From the complaints I hear from people using these mini-boards, stale shares and reliability are not an insignificant problem. I'd love to hear some first hand experience of the latter with an Odroid offering (I reckon the CPU and RAM should solve the stales issue). I may even dip my toe myself, but not until they appear on Bitmit or something.

Hmm weird, offer on Vircurex right now says BTC/LTC    0.00581002 which looks to me as if it means one litecoin is 5.81002 thousandths of a bitcoin, and that is offer, not ask. SO I do not know how 170 litecoins per thousand comes out as in any way similar to one bitcoin per thousand.

But I am not really awake yet so maybe I am seeing it a wrong way round or something.

A bitcoin per thousand freicoin sounds like a decent enough price to me that it could pry a few thousand freicoin lose from my cold dead hands or even when I actually do wake up my warm ones.
