You don't need a linux machine ! I've said about 5 times lol

Partition your drive using whatever OS you like. Just make sure you have two partitions. The first needs to be at least 1G the second can be as large or as small as you like.

How do you partition a USB flash drive? Windows 7 doesn't seem to allow that.

I can't get persistence working with unetbootin.

You mention TrueCrypt in the top post. Is the kernel compiled with DM_Crypt? If it is, I'd recommend using that instead. Unless you plan to be accessing the wallet file from Windows or Mac, DM_Crypt would be the easiest in the long run, and it doesn't have any weird licensing that TrueCrypt has. I use TrueCrypt on my gaming rig and DM_Crypt on my Debian server and Fedora laptop. I much prefer DM_Crypt, once you get used to it, that is.

Just thought I'd throw that in. You could even make a simple script to create an encrypted file with DM_Crypt if persistence is on, and another to mount it if it is detected. And just mount it to ~/.bitcoin/.

Hello -

Thanks Drgr33n for developing linuxcoin - i'm really enjoying it! I have been able to make my box headless and monitor it using GNU screen - i'm very happy!

I wanted to share a few tricks/hints that I picked up:

I know you said you were going to work on the start_mining script - I did not have success with it personally. I suggest that you give sample inputs for each field (like those that were cited in one forum post); or make the script smart enough to know the default flags, list the kernels, etc.
It is not immediately obvious that the license on the desktop IS a license. I dove directly into the shell and stumbled onto manually extracting the license before I realized that closing the info box would give the option to accept the license.
I'm surprised no one else has pointed this out, but ssh doesn't work until rsa and dsa keys are generated.

Code:

sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
sudo ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key

Thanks again for developing this distro.

Yes the SSH error was a issue with the original ISO. This ha been fixed since.

start_mining is very basic, I will be improving this very soon. I have also setup a wiki for information etc but I haven't had time to complete it. I'm hoping to have this complete in the next few days.

testing 0.2 @ 2x6990, doesn't work file manager (for me at least), and ati overdrive ctrl only sets clocks and fan speed to cores 0 and 1. Instead of it, im using this http://kde-apps.org/content/show.php/ATI+Overclocking+Utility+X64?content=107457, it works for all cores applying settings.

Thanks for the info. I'll swap to this app in the next release. Oh and yes confirmed there seems to
Be a bug with the file manager. If you disable the background it works. Very strange lol its on the list of todo's Wink

Actually, I pointed the SSH issue out a couple days ago. He updated 0.2a to fix the issue. If you redownload the latest one, it is fixed. You would still have the old version of 0.2a if you had to generate the keys, but it is fixed now.

booted up fine the first time, but now I keep getting this error when I try to run phoenix/phatk

Code:

[19/05/2011 16:41:06] FATAL kernel error: Failed to load OpenCL kernel!

Try using the root terminal vs. the regular terminal under the accessories menu or use sudo to elevate your permissions.

Either way resolved the "Failed to load OpenCL" error for me.

Should be plenty of bandwidth.

Hmm weird. My dedicated box was downloading at 4MB/s, not at the full 10MB/s I was hoping for Tongue

Oh, I've neglected to mention that the font color in the terminal is REALLY hard to see on the white/gold background. If the text was black (or if the background of the terminal was not transparent) that would fix things majorly. Granted, it can be changed manually, but it should work out of the box as far as readability.

All graphical stuff is yet to be complete. The wallpaper was just one from google images. The final version will be a lot more polished Wink

Fair enough. Cheesy

Just throught that it should be mentioned as a usability issue.

New version seems to work... but I'm not sure how to get it going over SSH, and then be able to logoff. I thought maybe screen, but it pops up another terminal. Either way, I've got it working and SSH seems to work now! Thanks again for working on this for the community! Now that I've got my 6990 mining (GUIMiner in Win7) and my miner mining with LinuxCoin on my 5750, I'll throw a coin your way in about 24 hours! Cheesy

Thanks again!

DISPLAY=:0 lxterminal -e"/opt/miners/phoenix.py ...

That should start a session with the terminal on the remote computer and you can log off and leave mining Wink

So that tells it to physically open the window on the remote screen? I've been using start_mining, but I guess that won't work? I've never had to do anything more than simple X11 forwarding. I can probably just do the above, then, I know the arguments I need anyway. Thanks! Cheesy

Yes you can just simply forward X but the trouble is if you then disconnect from the host mining stops. Using lxterminal to launch on the hosts display has its downside that if you dont have a screen you don't know whats going on but you can disconnect and move on.

Actually this gives me a little idea Cheesy

Who wants SSH support for start_mining ? lol

I would love it! One thought would be to redirect the output of the miners into files/dummy devices and then start_mining could display the stats? Or if instead of launching in another terminal, it just starts it there. Just some thoughts. That is kinda how I expected it to work, I didn't expect another window to pop up. Maybe this could even be a selectable option? I think the ability to use SSH is VERY important, especially for those with mining clusters.

how are you raising voltage in linux? Are you flashing with RBE beforehand?

You can manage voltage, mem clock, gpu clock etc with AMDOverdriveCtrl - well I hope the voltage slider is doing something!

drgr33n has kindly included AMDOverdriveCtrl as well as SDK 2.4 in the distro, so just look for it under "Other" in the menu (bottom left button) and experiment. !

BTW, 1.1 V is actually undervolted compared to what the normal high load profile was. Worth changing.

I have been using AMDOverdriveCtrl on my 5970 and it works great for downclocking the memory, the issue is that it only gives a max voltage of 1.05 for my card which is only enough to get to about 815mhz stable, about 1.16 is needed to get to 900+mhz
