Quick question: is it possible to mine with the stratum protocol through an http proxy?
Theoretically yes, but only if the http proxy is very permissive, and none will by default. A socks proxy will definitely work though.

I suspect that when switching users in windows 7 cgminer hangs. To p2pool it looks like it keeps on mining but with "100% local DOA" and the console interface is broken, nothing gets updated when I press Q or G etc.
Is this a known bug?

From what I have read, it is my understanding that cgminer does not like user switching.

Hi,
i have 4 zTex FPGA running with cgminer - on startup i get the following message:
HS FPGA configuration failed: DONE pin does not go high
The boards are calculating - but what does this message say?

Maybe not exactly a cgminer question...
I have to identical cards. How can i examine which one is gpu0 and which one is gpu1??

try cgminer.exe -n and check the gpu and the platform.

Hi, I'm pretty new to cgminer, have been using it to mine LTC, connecting to pools, and it worked great. Now I've switched to p2pool and there's a problem with (some of) my rigs: when p2pool isn't running (like when I reboot the machine that runs p2pool) cgminer just quits! It just stops working (tried all 2.11.x versions in windows 7), the window disappears and cgminer never restarts when p2pool is back up. This has never happened with other pools, only with p2pool... is there some special option needed to make cgminer "try" to connect to my local p2pool until it's back online and not just quit?

That's the ubuntu binary I guess? I'll rebuild it without needing dynamic libjansson
Yep, it's the Ubuntu binary.
I keep heavily marked up printouts of the README and SCRYPT-README my desk, Con, so at least one person has read them!

Hi, I tried to compile cgminer on OSX 10.6.8 with scrypt option to mine litecoin but when i start it I get this error
any hint to fix it?
Nope. Doesn't look like the scrypt opencl kernel compiles on the OSX opencl implementation. You're screwed. Quote

I now dont know further. I installed the driver for intel 3000 gpu, chipsetdriver and newest beta of catalyst for the 7970M. Then installed AMD OpenCL SDK 2.7 because i have read 2.8 is faulty.
But -n shows still only one GPU. At least its the 7970M. It shows Error -1: Getting Device IDs (num).
Starting cgminer brings this error again and then a black screen while the card is running. When i see at the pool (bitparking) the hashrate starts with a crazy high value and constantly drops then even though the gpu seems to run because of high temperature and high clockrates (gpu-z). I believe nothing is sent then anymore.
So what could i try now?

I now have another system to test. It has a AMD Radeon HD 7970M and a intel 3000. Its strange but cgminer.exe -n only shows the 7970M as a gpu, not the 3000. It was another way with an nvidia platform. There were 2 platforms and both gpus could mine.
The thing is... when i start mining, regardless if for bitcoins or litecoins, it starts, then the screen turns black and thats all. The fan is working hard. When i check the hashrate at the pool i see a hashrate going down and more down. Im not sure what happens because i cant see anything. When i try the debug-flag the whole thing is crashing.

Hi guys, I'm trying to mining LTC using 2x5870 with this line:
cgminer -o stratum+tcp://coinotron.com:3334 -u xxxx -p x --script
The command "--scrypt" aren't accepted by cgminer!
the output is: [2013-04-07 12:51:40] cgminer: --scrypt: unrecognized option
Then i tried with cgminer --enable-scrypt, but the output is:
cgminer: --enable-scrypt: unrecognized option
Even if the command "--enable-scrypt" is on the README file!

If you want to use scrypt you should write scrypt and not script...

Why?
4x7950 exactly like your card mines with 4GB system ram with:--scrypt -pool:port -O user:pass --lookup-gap 2 --thread-concurrency 21712 -g 1 -w 256 -I 19

I can't seem to monitor cgminer (2.11.4) with a web front end (Anubis) when I'm scrypt mining. If I do normal BTC mining it works fine. I've tried to explicitly set the api port to 4028 using the --api-port switch but it still doesn't work.
