very impressive

It's due for release over the next few days but as soon as I think I'm ready something else pops up Sad Most things are complete now just looking into quickly hacking up a small installer. 5830 was clocked at 1000/300.

Ug, I keep waiting on making the jump to Linux for the release version. Maybe I should just go for the beta and say F--- it.

I appreciate all the hard work you are doing.

Linuxcoin will be even nicer when you switch it over to Slackware.

Will we be able to use the same persistence files in the release version, or will we have to download a new one?

LOL sorry bud I know that i keep pushing the release date forward but it's hard not to because everytime the ISO is built something else hits my radar Cheesy. Plus it looks like I've got competition cough cough bamt hehehe Cheesy Only kidding  Wink

I promise I'll make a big push tonight to finish the installer and get this ISO out the only thing I don't want to is release with bugs again. I might ask a few to test 0.2-final before I release to the public. If you want to test send me a PM with your mining setup and I'll send you a copy.

I have 3 computers running 3 x 6970's at 950/300 for 408 Mhash/s and 2 5870's in my main PC along side a GTX 470 (for gaming only) at 960/300 doing 406-408 Mhash/s (will go higher but the power supply in my main PC is only a 1000 watt, and locks up if I do anything that pulls more power on the GTX 470 [1090t black edition, SSD, 2 HD... etc... gobbles power]).

I have new cases coming tomorrow. I will put 4 x 6970 in 2 of my computers, and 4 x 5870's in the third. Then I will put the remaining 6970 along side my GTX 470 (this has run fine before hashing away and playing games -  this PC will remain windows unless I can figure out if VMware will work for mining? then I could use Linuxcoin on that as well).

Anyway, I probably would not be a good candidate until like Friday to do any testing as I will be in hardware hell for a couple days. Had it been available to test a couple days ago, I would have been a good candidate.

If it is still not released by the time I get done with the hardware I will PM you and try to get some testing done for you.

Sent, even tho the miner is still only a test. I know a few other with similar setups who would like to test also, before major comitments.

Thanks for the interest guys !! Just a quick note on how your wallet is encrypted.

EDIT:

Added loop to test if bitcoin is running. As soon as you close the software linuxcoin cleans up so your wallet is no longer accessible until you open the secure bitcoin client again.
1) LinuxCoin asks for a password and encrypts the password sha1. This should protect against weak passwords Wink
2) LinuxCoin checks if an encrypteed wallet already exits. If so mounts the space, if not creates a encrypted filesystem using dm-crypt and luks and mounts your encrypted space in your home directory.
3) LinuxCoin copies the wallet.dat over to the encrypted space and symlinks it back to your bitcoin folder.
4) Linuxcoin detects when you close the bitcoin software (recommended if you want to be very secure !!) and cleans up after itself.
  
I think that's enough to keep most hackers at bay until you realize your wallet is missing and transfer your coins to a new wallet Cheesy

Here's the script if anyone wants to add it to previous versions.

Code:
#!/bin/bash
# Bitcoin wallet encrypter
# Zarren Spry <zarren@linuxcoin.co.uk>

#GLOBALS

LOOPDEV=$(zenity --entry --text "Please enter a loop device" --entry-text "/dev/loop8");

# Start bitcoin
bitcoin -min&

# create a loop dev for the filesystem
if [ -e "$LOOPDEV" ]; then
  zenity --info --text "$LOOPDEV already exists ! Moving on .."
else
  sudo mknod -m660 $LOOPDEV b 7 8
  sudo chown root.disk $LOOPDEV
  sudo chmod 666 $LOOPDEV
fi

# Check if a wallet already exists and if not create one
if [ -f /.wallet ]; then
sudo losetup $LOOPDEV /.wallet
RAW_PASSWORD=$(zenity --entry --text "Pleas enter your passphrase." --entry-text "Your passphrase here.");  
PASSWORD=$(echo -n $RAW_PASSWORD | sha1sum | cut -d "-" -f 1)
echo $PASSWORD | echo $PASSWORD | sudo cryptsetup luksOpen $LOOPDEV  wallet
sudo mount /dev/mapper/wallet ~/wallet
sudo rm ~/.bitcoin/wallet.dat
sudo ln -s ~/wallet/wallet.dat ~/.bitcoin/wallet.dat
        zenity --info --text "Your wallet has been mounted !"
else
# Create wallet
sudo dd if=/dev/urandom of=/.wallet bs=1024k count=50
mkdir ~/wallet
sudo losetup $LOOPDEV /.wallet
RAW_PASSWORD=$(zenity --entry --text "Pleas enter a passphrase." --entry-text "Your passphrase here.");  
PASSWORD=$(echo -n $RAW_PASSWORD | sha1sum | cut -d "-" -f 1)
echo "YES" | echo $PASSWORD | echo $PASSWORD | sudo cryptsetup luksFormat $LOOPDEV
echo $PASSWORD | echo $PASSWORD | sudo cryptsetup luksOpen $LOOPDEV  wallet
sudo mkfs.ext4 /dev/mapper/wallet
sudo mount /dev/mapper/wallet ~/wallet
sudo mv ~/.bitcoin/wallet.dat ~/wallet
sudo ln -s ~/wallet/wallet.dat ~/.bitcoin/wallet.dat
        zenity --info --text "Wallet encryption complete ! Your encrypted password is ${PASSWORD}."
fi

# Infinate loop to check if bitcoin is running. If not running clean up files.
while true; do
  check_running=$(pidof bitcoin)
  if [ -z $check_running ]; then
    running="0"
  else
    running="1"
  fi
  if [ $running == "0" ]; then
    sudo umount ~/wallet
    sudo rm ~/./bitcoin/wallet.dat
    sudo cryptsetup luksClose $LOOPDEV  wallet
    losetup -d $LOOPDEV
    break
  else
    sleep 8
  fi
done

could do with some error checking but pushed for time. If I have a spare hour I'll come back to this Wink

When you get to the black screen, enter a terminal by pressing Ctrl+Alt+F1 and delete xorg.conf located at /etc/X11/xorg.conf.  Reboot.

LOL I was only kidding !! BAMT rules too ! Love the web interface and how simple it is to get mining Wink Thanks for the recommendations bud !!

PS: I was going to ask you about maybe *borrowing* some of your work to implement into the PXE side of linuxcoin ? Would make a nice collaboration and I'm willing to give you a percentage of donations ? I'll PM you Wink
