Easy UASF Node in Debian VM tutorial

So if you have a moderately powerful gaming desktop with a Quad-Core CPU like an i5 or better and 8+GB of RAM, you can easily run your own little UASF node in the background. Once it's done syncing with the network, you won't even notice it's there. Here's how.
You will need :
The following assumes you know how to install Linux in a Virtual Machine
Step I. - Installation. Go through expert install and set up a base system with only ssh server enabled. For partitioning, you can do just one big disk and everything in one partition, but if you happen to have a computer that has both SSD's and HDD's, it would be optimal to create two virtual disks and use a small one for the OS on the SSD and a larger one on the HDD in a custom mount point for the blockchain. Reboot and ssh into the server.
Step II. - Build requirements. A few things need to be taken care of. First, you'll want to edit the /etc/network/interfaces file and set up a static IP. Once that's done, stop by your router and make sure that traffic on port 8333 is forwarded to your debian VM. Then, install some packages we need :
apt update apt upgrade apt install build-essential autoconf libssl-dev libboost-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev libevent-dev git libtool pkg-config 
The next one is a bit more annoying. We need Berkeley DB 4.8, and it's a little old. It's packages are in the Debian Squeeze archives, so in the /etc/apt/sources.list file, we need to add :
deb squeeze main 
Then remember to update again, and install the thing :
apt install libdb4.8++-dev libdb4.8-dev 
If you intend to also throw on xorg and a UI, you will want Qt as well. Otherwise skip this last step.
install libqt4-dev libprotobuf-dev protobuf-compiler libqrencode-dev 
Step III. - Build time
#Starting from /home/yourUser git clone -b 0.14-BIP148 cd bitcoin ./ ./configure make make install 
That's it! Well, mostly. Start it with
bitcoind -daemon -disablewallet -datadir=/whereveyou/want/youblockchain 
...and wait about thirty hours to sync with the network. You may want to visit the /whereveyou/want/youblockchain directory and create a permanent bitcoin.conf in there. To enable RPC calls to the server and get it to accept bitcoin-cli commands you'll want to use it to create a usepassword and copy that to your user's /.bitcoin/bitcoin.conf.
Minimal bitcoin.conf example
daemon=1 listen=1 disablewallet=1 server=1 rpcuser=bob rpcpassword=bob's password 
Security I recommend you disable password login and use private key authentication only on ssh, and also restrict iptables rules to the bare minimum that must be allowed for this application. You will need this in your iptables script :
# Allows BITCOIN traffic from anywhere -A INPUT -p tcp --dport 8333 -j ACCEPT # Allows RPC calls to the bitcoin server from localhost -A INPUT -p tcp -s --dport 8332 -j ACCEPT

I have even tried to remove the key manually with apt-key del B38A8516 and reinstall it. I always end with the same expired keys...
Anyone have a hint on this ? I'm completly lost...

To the moon! Dogemining with BFGMiner, Debian, and ATI.

Visitor from the future! Hello. I'm a newbie digger and recently setup my first dedicated mining box in Debian. I'm not the most experienced Linux user, but the machine had started with Debian Squeeze and I couldn't find its old Windows key. (Also please forgive formatting errors, I'm new to this whole "Reddit" thing as well.)
I found a number of guides to misdirect me on my way, so I decided to write up a sort-of (or at least hopefully up-to-date) guide to create a Dogecoin miner on Debian with AMD cards, using BFGMiner to mine coins.
Expert digging shibes: I would certainly appreciate feedback to improve this guide.
This is not a headless mining guide. I have not reached that level of mastery yet, though I believe it is well within reach.
You can refer to this wiki source to understand the output from BFGMiner 3.10.0. The one gotcha I've observed is that BFGMiner will happily start off showing hash rates in KHash/sec, and after the first accepted block it will jump to MHashes/sec. When I first saw my hash speed appear to drop from "250" to "0.2", I panicked a little before seeing it had changed its orders of magnitude.
If you think you're still mining slowly, you might need to bump up the intensity for BFGMiner. Higher intensity means more work, and it's possible to create hardware failures if you set it too high. For my HD 5870s, I use an intensity of 12. You can either set the intensity by adding "-I 12" to the ./bfgminer line of, or you can adjust the value by pressing M in BFGMiner and working through the menu system from there.
Bonus: Multiple cards
What happens if I have multiple ATI cards on one rig, you ask? I had the same problem, and OpenCL would only recognize one of them! It turns out that there's an easy solution, but it costs $1.25 in resistors from your local radio shack:
Plug the finished product from there into your second card. If you have more than two cards, you'll need to make one for every card you want to recognize without a monitor attached to it. Reboot and restart your mining, BFGMiner should recognize all of your cards now.
In theory, the above technique should allow you to run completely headless, as long as you also install SSH and be sure to have your script export DISPLAY=:0 before running BFGMiner. I haven't tried this, though.
Happy mining and welcome to the Moon! I hope this is helpful to someone.

Litecoin daemon randomly crashing without errors

I just installed bitcoind, litecoind, and dogecoind on a new VPS running Debian Squeeze. The daemons were built from source. Bitcoin and dogecoin synced fine, and run just fine. Litecoin however, keeps randomly crashing, and I had to constantly restart it to allow it finish syncing as I thought it's something to do with RAM or buffers or the sort. Even after it finished syncing, it still randomly crashes without any clues. None of the logs in /valog/ have any mention to this. Here's a link to the last 20 lines of litecoin's debug.log when it crashes on several occasions:
And memory usage:
What on earth is going on here?

The new debian source package (version 0.7.2-2) was uploaded yesterday, and is waiting in the NEW queue for one of the ftpmasters to approve the new bitcoin-qt package name. And thanks to the great work of Jonas and the rest of the bitcoin team in Debian, you can easily test the package in Debian Squeeze using the following steps to get a set Install Bitcoind From Source On Debian Or Ubuntu Linux.
