OK, so I've learned how to install and use bitcoin-qt, insert bootstrap.dat to get up to date, run a full node and run headless bitcoin core thanks to this forum.
Now that I've got a headless node running I'd like to limit my upload speed, if possible, to keep it below 50Kb/s. My connection is 100Kb/s max and I don't want it interfering with other stuff I'm running, like torrents.
I know I can limit the number of connections (thanks DeathAndTaxes) but this doesn't necessarily mean that my upload isn't being max'ed out.
Is there a command line option to set a maximum up speed?

Actually, I might have got that wrong. It goes in .bitcoin on Linux, I think.

If you're using Linux put in in your main Bitcoin directory, the one above /bin/32 or bin/64.
Don't forget to delete it once you've fully synced to free up 17 gigs. You don't need it anymore once it's finished sync.

I'm not sure, I was asking based on my own assumption.
I assume that because these wallets work in a different way (some are deterministic, some use a copy of blockchain) then you couldn't just copy the wallet.dat to a different type of wallet and expect it to work. Am I right?

Forgive my ignorance, but I assumed an armoury wallet.dat file is a different format to an electrum wallet.dat or a bitcoin-qt wallet.dat.
You couldn't just copy it over and expect it to work with different software, right?

This has got scam written all over it. Why would you store 100 BTC without a password written down or something you'd definitely remember.

Ah, that's good to know. I'd already allowed ufw through port 8333 but hadn't forwarded the port in my router. I've done that now and currently have 11 connections, so I must be running in full node mode.  |

Cheers,
Just tried it and connections=6 after startup, then increased to 8 moments after. That means I've got a two-way node running, right?

I've got bitcoind running by using the suggested username and randomly generated password it gives you, by inserting them into a bitcoind.conf file.
It's currently using about 850MB RAM and the CPU is idling, after it used a lot of CPU for a minute or two. I assume that was when it was updating what I've missed in the blockchain over the last couple of days.
How can I now check that it's running OK: i.e. that I'm connected to nodes and I have incoming and outgoing traffic?
It's easy to see in bitcoin-qt but as bitcoind is headless I'm not sure if it's actually working as a node.

Sell them on localbitcoins.com? It depends what country you're in.

I'd like to add that it would be nice to the bitcoin network if you carried on running bitcoin with the blockchain.
You can still use electrum for your transactions but only bitcoin core will actively work as a node and help out with network traffic.
If you have a decent PC and don't mind the extra overheads of running a node (bandwidth usage, CPU & RAM usage) then you'd be doing your bit to support bitcoin.

LastPass also lets you backup all of your passwords into a csv file on your computer, should anything happen to the Web server.
I make a backup about once a month and store the csv into a password protected rar file, using a Sha256 hash as the password, then shredding the original csv file.
In the unlikely event that someone gets a copy of my rar csv backup good luck to them trying to brute force a sha256 password.

I've been Lastpass user for nearly 3 years now. It costs me about $12/year but that's nothing to have peace of mind over my banking and shopping passwords.
I also use a YubiKey for multi factor authentication if I'm away from my own computer. That'll set you back another £25 but it's a neat little gadget.
I'm not saying don't use Keepass, or another free alternative. Just saying LastPass is really good too.

Last night I bought 8gb dual-channel Corsair Vengeance RAM from eBay, so I can't wait for that to turn up in the next couple of days.  I want to try running the headless version in the meantime and check out how much it uses compared to QT, but I'm a bit of a noob. How do I execute the headless version. Is it bitcoind? When I try running bitcoind in the terminal it runs for 30 seconds and then terminates with the following message: It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=65cBHynVPD1Ffod8JPtMvw6eMuEsq1ASDNEYLQL1i2Ya (you do not need to remember this password) The username and password MUST NOT be the same. If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" admin@foo.comDo I need to edit a configuration file to keep it running? |

If it's gonna take another year or two that's good enough for me. I've been getting impatient for pay days, so I can buy another coin before all this mad speculation that it's going to soar.
If the price stays stable for a year it means I can buy steadily once a month and slowly accumulate coins at a price I can afford and relax without the dreaded feeling that I'm gonna miss out.

While it's syncing from file (which it says in the bottom corner if you're using the GUI) it also verifies the blocks using the network. So you don't have to worry about downloading a dodgy or corrupt bootstrap.dat.
Once it finishes syncing from file it will change to syncing from network to add the extra blocks since the torrent was released. Much faster than doing it from scratch.

Seriously, download bootstrap.dat from here:
sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/
It will get you closer to a full sync far quicker than using the client.
Just pop it into the relevant directory and start your client. It will do the rest seamlessly.

You should search for a torrent of bootstrap.dat. The latest torrent is about 17 gigs and will get you with about 12 weeks of sync.
Pop it into your bitcoin-qt directory (I can't remember exactly which one, there are guides) and then delete it once you're fully synced to to free up 17 gigs.

I'm using an AMD APU, DeathAndTaxes, without a dedicated graphics card. It automatically assigns a portion of RAM as video memory. They're designed to have faster graphics depending on the speed of your main memory.
I'll check out your other points tomorrow when I'm home as I'm posting from my phone right now.
I've been hankering for 8gb RAM for a while now and this might sway it.
Oh, and I haven't made a single transaction with bitcoin core. I'm just running it as a node. I load up electrum if I need to make a transaction.
