[ANN][ENRG]Energycoin - Android Released - Bittrex -

[Harcon]

I can think of two issues

First, have you forwarded energycion port to your PI?

Second, maybe your internet connection is a bit slow, as the pi is slow, having also a slow connection can cause your blocks to arrive too late to be confirmed by other peers.

I mint with mi PI since the release of ARM 1.1.2 build and it's very rare that my minted block don't get confirmed. (but my connection is light speed)

 Ty for your reply.

 Nope, no forwarding to the pi and yes I will try that. As far as the connection speed, I have cable at 15 Mbit/s upload and download and my ping was at that time between 15 and 30ms. So there should be plenty of speed for blockchain transactions and since my Pentium 4 is not forwarded and works on the same connection but dose not have this problem, it may not be the connection or forwarding ( though I think the forwarding for the pi is a great idea and will do it )

 I have made a few changes to the pi in the last few days that might help, most notably I have as much RAM freed up as I can. Seems I had GPU shared at 128mb and since the pi is headless I did not need that much dedicated to graphics. We shall see how it goes when I start putting coin back on the pi, but if you have any other ideas, feel free to shoot them my way.

Hi, Im new here but I have watched this thread for months. I am also a big supporter of Energycoin and would like to use it with my Pi but I do have a problem. When I have coin in my Pi wallet, the staking of coin works but it dose not work well. I will get situations where more often then not, I will stake and those staked coins will never get even 1 confirmation. In fact, I seem to get a condition where it is not even clear if the stake was rejected.

 I think out of 10 stakes, there was only one that actually went through with the remaining 9 not having a conclusive result one way or the other. The fact that I got 1 successful stake means it works, but I have no idea what to think of the other 9 staking transactions that had no result at all.  If you contrast this with my Windows driven Pentium 4 who's wallet always gets a conclusive result one way or the other ( mostly successful ) Then I would have to guess that the pi ( even OCed to 900 mhz ) might be to slow to keep up with the network. Lord knows it seems to have problems keeping up with the initial sync of the blockchain.

 Having the pi work with Energy wallet is a big deal for me because the Pentium 4 uses far more power then is needed to stake coins and also since my pi is up 24/7 for FTP/SCP server, it would just be nice to have my coins there. 

Welcome,
You can earn 10K ENRG with jour PI if you post on the forum and follow the instructions:
http://energycoin.pw/forum/index.php/topic/90-reward-energycoin-eco-green-node-deployment-project-on-raspberry-pi/

Indeed I may just do this. I would like to ask though about bandwidth usage. I have unlimited bandwidth from my ISP but I am still careful with how I use my connection.

First, have you forwarded energycion port to your PI?

Peercoin has a tool to foreward the port to router:
http://www.peercointalk.org/index.php?topic=2702.msg23519#msg23519
Can you check if we can change this tool for EnergyCoin wallet?

 On the topic of coin security, those running Linux ( including Rpi ) need to be careful. A "catastrophic" bug was just found in bash not long ago. Apparently under certain conditions attackers can use it to place malware on a linux system. The specifics where not given in the story I read about it, so I do not know what the problem is or how it can be used in an attack. I do know that it has not been fixed yet. 

I should actually say that it effects Unix and everything that comes from Unix using bash. So it is not just linux.  I personally still feel safe enough to keep coins on a Linux system, but if anyone has concerns you should google it and do some research.

It's a little bit unclear, do we have to search catastrophic linux bug in Linux ? we will find a lot 

 "Bash bug" or "bash flaw" is good as a search term

[crypto4jan]

OK is is good to know that PI not completely save and espesialy when I want to setup a node.
Right?
I'm in the experimental phase and also instaled Peercoin node (just curious how that works).
The peercoin software http://www.peercointalk.org/index.php?topic=2702.msg23519#msg23519 overwrites some instaled programes (after warning).
The EnergyCoin wallet was not functional after peercoin intstall procedure.
I did a reinstall of EnergyCoin and have to see later the result.
The message was scanning blockchain integrity.....
I also want the 10 PPC reward from peercoin so I want to have both working on my PI and maybe also SuperStake wallet (just for fun).
Any tips?

This coin has an active comunity. that's nice

Yes, sometimes you post here.
It is a living coin and we have faith for a good future.

 Ok, first, the bash issue. If you take a look at this URL below it will give you the test for the flaw and at least a partial fix ( though I think it has been fully fixed now ). When I tested my pi running the latest Raspbian image (09-09-2014) it had the flaw and I simply updated bash and applied the partial fix.

https://www.digitalocean.com/community/tutorials/how-to-protect-your-server-against-the-shellshock-bash-vulnerability

 As to my speed issue with the pi, I have tracked that down to the speed of the SD card that I am using. I do not have an external HD on the pi and I will not have one until the 1st of Dec this year. Originally I thought that my Class 6 16GB SD card would be just fine until I got my external drive but it seems that what really determines the speed of crypto coin transactions is your hard drive speed more then the speed of the CPU.

 Generally though, the bash flaw should at least be fixed before you trust the pi with your coins. At this point it should just be a matter of updating your bash. Just be sure that you know what the status of the fix is. It still may be just a partial fix but even that should be good enough.

[Harcon]

Ok, so, Bash flaw:

If you use Raspbian, that is adapted from Debian wheezy, the default system shell is not bash, but Dash, so you should not be impacted

But default user shell is bash, so it can be changed if needed but I don't think energycoin-qt use user shell (EnergyCR should check and give us the answer, if it use default user shell or default system shell)

http://unix.stackexchange.com/questions/127647/why-is-the-default-shell-in-debian-7-bash

If you mint on you raspberry, you should install only Energycoin-qt, and forward nothing or only energycoin port, if you forward nothing, it will not be a full node
don't enable ssh or any remote access tool, don't use the raspberry pi for anything else.

It's not gold security rules but minimal security advises  

 When I do security audits or maintenance related to security I always include the possibility that someone will gain physical access to my hardware. With the bash flaw, no one yet knows all of the possible ways this vulnerability can be exploited indirectly. I almost always think of any crypto coins I keep on a device as worthy of paranoia as far as security. It is true though that it is less of an issue if your default is dash.

Is there a way to speed up the blockchain download on raspberry pi as it seems to take forever

[crypto4jan]

Is there a way to speed up the blockchain download on raspberry pi as it seems to take forever

You need to forward port 22706 to router.
I don't know if that solves he problem, I 've to forward the port but I need help to fix that.
The downloading on PC is also going slow in comparing to 3 other wallets I've running.
Maybe because the stake is producing so much transactions that the block chain is growing fast.
On PC I've 8 connections on raspberry pi now 5 but I hope that it becomes a full node this afternoon.

The cpu is slow on pi, so checking the blockchain is very slow.

Use an sd card class 10, but it will be slow for the initial synch.

For peercoin I have to open firewall: Open it up with 'sudo ufw allow 9901
I do the same now for the enerycoin port 22706

I've forwarded the port but now only 4 active connections.
Is there somthing else I 've to configure in the wallet or on the PI?

[Harcon]

 You'll almost certainly have to wait with the pi. Mine always takes around 96 hours to finish. The problem is the blockchain verification. You could download the whole blockchain and drop it into place and it still basically takes the same amount of time. This process is only faster with a faster disk, so class 10 card would be best. overclocking to 900 mhz or more helps, but not so much that it is really worth it. Generally the faster you push the pi, the more chance you have for SD card corruption. At that point you have to reinstall and go back though the blockchain download/verification.

 That reminds me.. Anyone using an SD card should go ahead and clone the card as soon as you have everything setup and the blockchain downloaded and verified. That way, at least if you do have to reinstall, you can just go back to that image you made of your SD card and you only have to download/verify the part of the blockchain that was created after your image was made.

[crypto4jan]

Now 9 connections and it works ok together with Peercoin node.


As you can see I reward myself with 10k ENRG from the EnergyCoin Foundation
You can also be rewarded if you setup a EnergyCoin node and if I you are smart you can also rewart 10PPC (now worth 10$)

Will there be some exciting news later this week about the long-awaited Android wallet ?

[rockrabbit]

Will there be some exciting news later this week about the long-awaited Android wallet ?

i think it will be soon.

[Harcon]

 My pi should be syncd in around 36 hours. ( give or take a few hours ) Port forwarding is working fine. Is there anything left in the tip pot for another pi owner? 

[Harcon]

I still have 31 connections on mine 

 I did just have 18 connections until I shut the client down to make an adjustment. I am guessing that's where it will go back to once the Energy finishes loading. So, I guess I lose on the connection count competition. lol

[Coinr88]

How long does it take for a synced wallet to start on raspi? Cause it is stuck on the Loading block index screen since 15 minutes now with cpu usage 100%
