Well i am using one of the most insecure operating systems on the planet .... what was it again .. oh yes windows Wink
But even though its leak like an open door on my house untill now i never ever had a problem with my security for lets see 12 years now.
So yes i take security not for granted and even though many have had issues with their os, i still can say never had an trojan or virus in these years take anything from me.
The most dangerous thing is using the cloud in a insecure way, like people trusting online storage and such or even gmail for that matter...
Nobody seems to see the risk in these and send files and very privacy related stuff to them just as easy as if its the most secure thing on the world
Hell on my wifes work for instance most people on the job still put stickers on the pc for the others so they can login.
They simply forget people walking in and out all the time ..

Not one of them, but the most.

The fact that you are unaware of what happened doesn't mean it didn't happen.

I'm purchasing a 1.0Ghz Fanless Mini PC to store bitcoin savings (don't have any yet). Found a Taiwanese company that sells them cheap:
http://www.ewayco.com/100-low-cost-pc-products-low-cost-systems-embedded-systems-servers-lcd-pc-panel-pc.html

For the OS I'm thinking about a headless (no GUI) version of Ubuntu server. Most of the time I'll have the machine switched off unless I need to send bitcoins to my working wallet (hosted on a Widows box). Access to the machine will be via console or SSH.

The partition will be encrypted too.

I'm buying two of the Mini PC's so it could be interesting to put some coins (say 20) on there and run a competition to see if anyone could get them, obviously I'd leave it on, and provide an IP address. PM if you're interested?

A Raspberry Pi for 1/4th the prize would nice (and portable and easy to keep on a safe) for that:

Looks interesting and I can't wait till it's released. Till then I've already paid for the mini Fanless PC.

does the new bitcoin client that encrypts the wallet make this method useless?

Not really. There are numerous Trojans and other vulnerabilities with certain operating systems. If you plan on storing anything more than a trivial amount of BTC I'd strongly suggest taking extra security measures. For me this means storing them on a dedicated (mini) PC.

So when I created my super secure wallet and put all my BTC savings in there, how much should I keep in my every day wallet, because its quite some trouble to get to my bitcoins in my super secure wallet?

Would it be a good idea to have an easy to access wallet that is more secure then the every day one for medium size bitcoin purchases.
I was thinking of creating a new user on my PC with an encrypted home dir (like my normal user has too).
In this account I create a wallet and only use this account for sending and receiving BTC, no web browsing etc.
Now even if a wallet stealing mining software or website gains access to the every day account it can't access the wallet file in the second account because the home dir is encrypted.
But I can still quite easily switch to the second account do my Bitcoin stuff and go back to the normal account for every day stuff.

What do you think? Useless or would this actually help make the wallet more secure? I kow that this does not cover all possible attacks.
Thanks for your opinions

It's not difficult to transfer between wallets, even via command line.

I've decided to leave my dedicated bitcoin (mini) PC on, and connected to the network at all times. This way I can use putty/ssh from work and transfer at any time.

0) Damn Small Linux is 50MB in size, install it somewhere and install bitcoin on it.
1) Encrypt the disk/file.
2) Use a Cloud-based service like JungleDisk.com to backup your wallet/distro. It costs $5/month & the first 5GB is free.

Good idea, although DSLinux can be tedious for beginners. But I like the elegance of your solution.

One potential problem: If we think long-term, DSLinux-version.today might not necessarily be able to boot on modern hardware in a few years.

Don't forget Puppylinux...
It also boot in Gui, sadly it only have restricted locale, but it's very nice, atleast those times I've tested it.

Post #5... Yay... Only Wait remains...

LVM split across 2 disks with one big ecryptfs ext4 fs. Within that runs a kvm which runs another ecryptfs ext4fs, which holds a truecrypt disk that needs to be mounted, once mounted, my wallet. Packets are monitored at each level. What do you guys think?
