RaspNXT - a standalone NXT environment for the Raspberry Pi

UPDATE 2014-01-08: NXT 0.5.3 coming soon
UPDATE 2014-01-05: NXT 0.5.0 cancelled
UPDATE 2014-01-02: NXT 0.4.8, update script, blockchain-less



This package contains the current stable version of the NXT server and the Embedded Version of Oracle JRE that you can run on your Raspberry Pi as-is. You can get it from my public node server (hash checksums coming soon). This archive contains most of what you might need, including some helpful utilities and scripts.
If you have the JRE already or insist on using another one, try this archive. Both links always link to the newest version of the package. You can get older versions or other stuff from the nxt root of the server.
Notice: Unlike the initial version, there are no block files in this version of the package. This reflects the makeup of the main NXT releases, which are now also blockchain-less. If you would rather use a basic blockchain to update from, but don't have one yet, you can download one of these.

To download and run it on the Pi, do the following steps in a local or remote console. I assume you have the Pi up and running already, using e.g. Raspbian. I myself am using Raspbian, however, the package should also work with other distributions.

Code:
wget http://109.230.224.65/~nxt/nxt_rasppi.tar.gz
tar -xpf nxt_rasppi.tar.gz
chown -R *youruser*:*yourgroup* nxt/
cd nxt
ln -fs webapps/root/WEB-INF/web.xml configfile
./run_nxt.sh

I now have incorporated my public node update script into the package. Called automatically by the run script before starting the JVM, it fetches a list of well-known public nodes and puts them in your config.

You can tweak the JRE call in the run_nxt.sh script if you want. After some testing with the new version, I have found that not that much memory is needed.
Also, I put a symlink in the rootdir called configfile which leads to the web.xml file, for easier access.

I recommend running the server in some sort of backgrounding context, as it is basically a daemon. Use a multiplexer like screen or at least use nohup. For a more comprehensive guide on setting this up, I recommend this how-to which also references this package.

If you want to access the client from another machine - which you probably do want when starting the server or using the Pi as a whole remotely - remember to put your accessing IP or the "*" wildcard (no quotes) as allowed addresses in the configfile.

Have fun with it, and feel free to post some impressions of RaspNXT on your RPi Smiley

You can tweak the JRE call in the run_nxt.sh script if you want, most importantly of course: the memory usage. I have found that my preset values are more than enough, so you might want to try to tweak them lower, especially if you want to do something else with the Pi while running the server.
Also, I put a symlink in the rootdir called configfile which leads to the web.xml file, for easier access.

someone pls FIX a thread with this on nextcoin ASAP!

Everything is messed up for me. I have a transaction that appears in the block chain info website under transaction ID and also in my list of transactions, but my total NXT doesn't count it.

Client side, it keeps getting confused and now 99% of my NXT is not accounted for. Right after refreshing and logging in again, I get to:

      24430      4747512364439223888      12/25/2013 9:06:56 PM   
4      80 + 4      544 B   
1      12062559375247828788      932 %

With over 1000 unconfirmed transactions. I have waited for 10 hours for things to clear up, but if anything it is getting worse. I have the latest 4.7e version started fresh in its subdirectory.

What am I doing wrong? Please somebody help me, I will be going to airport soon and won't be able to be online much for two weeks and I really need to get this fixed first. The fact that the server side block chain website can miscalculate the total NXT in my account seems to be a pretty big bug.

please help!

James

War chest update

1. I have received several PMs with offers to help set up public nodes
2. Due to the very high volume of posts, I have not been able to check through every one looking for most suitable/deserving member to disburse the funds.
3. We have another 260K in the fund available for immediate disbursement. So, here's my plan.

Anyone who has a history of setting up nodes and who have a specific plan of action, please post your requirements here and follow up with a PM to me. I'll disburse funds to all legit requests asap.

Conditions:

1. You must describe your specific plan and how much Nxt you need to implement the plan.
    Eg. I need xx Nxt to set up nn Nodes in these locations by this date.

2. You have to report back to the community after you've implemented your plan.

Thanks.




Hi, so i've decided to help nxt community a little bit by providing public node 24/7 from my dedicated server
My spec :
8 core processor (intel),2GB RAM, Up-to 1Gbps traffic, running 24/7 located in Indonesia
I've already implemented and running version 0.4.7e @ 203.174.12.17

Please donate me some Nxt to start and keep server running. I dont want to ask for specific amount since i''m just want to help this nice community and watch it grow bigger and better  Smiley

Nxt : 6085825983472667622

Thanks.

Don't bother then, relax, 99%+ u see some type of crash when return. We're under attack, forks'es rate very high, cos network's constantly splitting. If zombies can grab u 720+ blocks away (at now much less diff. needed) from main chain u'll stuck.

The forum seems perma-DDoS'd, so I didn't really bother writing much there. Only put a link in that one thread.

Thanks, I will look into the sticky when it comes back online.

So yesterday I created an address by choosing a pass-phrase, but now, when I get to localhost:7874 and put that pass-phrase, a different address appears. How can I access my original address?

Give me your new address and old address and I will check the balance in the old one and reimburse you what you have lost (within my means) if you can't remember it.

Just remember the new passphrase!!

I'd really appreciate your help. My new address is 11167183571272945597. The old one is 15833482877956085624.

He received a transaction with short deadline that wasn't included into re-forged chain. I sent him all the info and he will ask the sender to repeat the payment. Luckyly the sender is a good guy so there won't be any problems. But next time people should refuse to accept payments with short deadlines (less than 24h), coz a blockchain reorg can invalidate them. I think we should change deadline minimum value from 1 min to 24 hours.

Xmas Update!

Another 10 nodes have been deployed in Dallas. DNS is propagating and will soon be seen as node31-node40.

That's 40 nodes in 4 geographic locations!

The nxt cluster of 10 will be with a new cloud provider so it might take a bit to code up the differences.

ALSO - the first vanity node is launched - panda.nxtbase.com - hallmarked by the sponsor. Hot damn!

Deployment update:
Funds received - 237'500 nxt
Nodes deployed - 41
Nodes queued - 37

Funding goal remaining for 100 nodes by Jan 3 - 64'000 nxt

To sponsor a node for 3 months (end of March), send 3000 nxt to 11243542237777034551. Vanity nodes are 4500 nxt and will have your hallmark (good large stakeholder PR).

I have a bunch of dedicated servers, but all at one data center. Is there any benefit from deploying the server code on more than one of the servers?

What would the typical CPU load be? These are compute oriented servers, so not much bandwidth for each, maybe 10mbps.

How much would this help?

How to refuse payments with short deadlines? We can just ask the sender to put a high deadline? Or is this somehow configurable for the receiver?

cpu load is negligible.
every node helps to split the load.
