    Apparently you copy-pasted the file, loosing some important details. Use raw view instead (https://github.com/m0mchil/poclbm/raw/master/poclbm.py). Perhaps for other files too.

    No offense intended Smiley, I asked questions that probably seemed stupid to the people that answered me.
    Now I'm happily crunching at 600mh/s thanks to the people that helped me out.

    Maybe you should simply clone the git repo so you can transparently get upgrades and forget about this kind of issues altogether
    You need to apt-get install git-core and then
    git clone <url>
    and then you can just git pull from time to time to upgrade.

    It runs for 4-5 seconds, then asks me for my user-password again.

    Code:
    ~/bitcoinminer$ python ./poclbm.py -d 0
    Enter username for jsonrpc at 127.0.0.1:8332: berserk9779
    Enter password for berserk9779 in jsonrpc at 127.0.0.1:8332:
    20842 khash/sEnter username for jsonrpc at 127.0.0.1:8332: berserk9779
    Enter password for berserk9779 in jsonrpc at 127.0.0.1:8332:
    20847 khash/sEnter username for jsonrpc at 127.0.0.1:8332:

    By the way, before poclbm I need to run bitcoind. Is there an option to have it running with the gui open?

    If you supply the user-password on the command line, you won't get asked for it again:

    Code:
    ./poclbm.py --user=whatever --pass=whatever

    That's not ideal from a security point of view, perhaps someone will suggest a better way.

    You can use bitcoin instead of bitcoind, provided you are using a recent version of Bitcoin (0.3.15 or later) and the latest version of poclbm. This gives you the GUI, plus OpenCL mining.

    Or you can just edit poclbm source for a quick slightly securer dirty hack

    It's finally up and running. 22 Mhash on average on a Nvidia 9800GT

    But it only works with bitcoind.

    And I had to start it like that:

    Code:
    ./bitcoind -rpcuser=berserk9779 -rpcpassword=

    and

    Code:
    ./poclbm.py -d 0 --user=berserk9779 --pass=

    Has anyone tried connecting to the bitcoin-server from a different machine using m0mchil's miner?

    I am using Windows binary poclbm.exe. I have my bitcoin -server running on a local machine and have no problems connecting from poclbm.exe and generating using my GPU on the same local machine.

    When I try to connect to the same bitcoin -server from a different PC using:

    poclbm --user=user --pass=password --host=remoteip --port=8332

    I keep on getting the message "Unable to communicate with bitcoin RPC".

    The firewall on the PC running bitcoin.exe is disabled.

    Is what I want to achieve at all possible?

    I think you should substitute remoteip for the actual private IP of the local machine where the server is running (usually 192.168.x.x)

    It's me again...

    I managed to connect to my bitcoin -server from two different remote machines.

    With the third one I am getting the following error:

    Code:
    pyopencl.RuntimeError: CommandQueue failed: out of host memory

    Does this mean my server has no more memory to accept more miners?

    Added update of block time every second and support for targets < 32 bits. Output now shows block hash and acceptance status.

    Nice, with Bitcoin 0.3.19, poclbm 20101214 and catalyst 10.12 I get around 82000 khash/s now instead of 78000 with the old versions.

    Regarding my previous post about the "host out of memory" error - I figured that on some systems if you install ATI Catalyst into C:\Program Files\Ati Technologies there is some sort of an error and it is not possible to open the Catalyst Control Centre (this was causing my issue).

    The solution to this is to completely uninstall all ATI software and put it into a different directory - I put it into C:\Program Files\Ati and the problem was solved.

    Apparently AMD are aware of this issue.

    The new version seems like it may be running at 1-2mhash more than the previous version  Grin
