run masternodes under ubuntu command line

how to run a remote masternode using ubuntu command line

nerd level 6.

please ensure you have a working knowledge of masternode setup before attempting this and a controller wallet configured.

refer to

http://bumbacoin.blogspot.com.au/2016/07/how-to-setup-exclusive-coin-master-node.html

in this guide you will be modifying the exclusivecoin.conf file for remote masternode ability.



...

i have pre-compiled the ubuntu daemon so it's a matter of fetching it,
setting up the .conf file, syncing it, setting up the masternode file and starting masternodes.

all files are available here

https://github.com/exclfork/ExclusiveCoin/releases/tag/v1.2.0.0-daemon

--

#get daemon from github
wget https://github.com/exclfork/ExclusiveCoin/releases/download/v1.2.0.0-daemon/exclusivecoind-ubuntu-v1200

#rename for ease of use
mv exclusivecoind-ubuntu-v1200 exclusivecoind

#change permissions so you can run the daemon
chmod +x exclusivecoind

#create and modify datadirectory and conf file, you need to be in home or ~ directory
cd
mkdir .exclusivecoin
touch .exclusivecoin/exclusivecoin.conf
nano .exclusivecoin/exclusivecoin.conf

### now you're in a text editor you want to add
rpcuser=yourusername
rpcpassowrd=fancypassword
daemon=1
rpcallowip=127.*.*.*:*
server=1
port=your port number
rpcport=your rpcport number
masternode=1
masternodeprivkey=from your controller setup
masternodeaddr=ip address of this wallet:port

note:
setting a port value is only required while running multiple wallets on the same system (otherwise they will attempt to use the same ports)
otherwise you can omit those lines and use default port of 23230


#then to quit
[ctrl]+x
Y
[enter]

#now you can start the daemon and let it sync
./exclusivecoind &

#you need to stop/restart the daemon to enable the masternode.conf
./exclusivecoind stop
./exclusivecoind &

#to check that you are synced
./exclusivecoind getinfo

#then compare blocks to height at https://www.cryptobe.com/chain/ExclusiveCoin

#when the wallet is succesfully synced start/register the masternode from your controller
it should pick up the registration automatically and start running.

#for confirmation of success it can be useful to check your masternode for entry in the masternode list via command, please exclude your port number when entering IP
./exclusivecoind masternode list full yourIP

this should output any entries with your ip.
the very last number is a time stamp, the second last number is your rating, it should be greater than 0,1

also you can monitor the output of the debug.log for lines containing something similar to

2017-07-18 02:28:38 CActiveMasternode::EnableHotColdMasterNode() - Enabled! You may shut down the cold daemon.




#also there is a bootstrap available here
http://cryptochainer.com/dir/?page_id=881



--
#handy daemon commands, the daemon is a command line version of the wallet,

#start daemon, the & symbol is necessary to free up the command line
./exclusivecoind &

#stop daemon
./exclusivecoind stop

#gives information regarding client and blockchain
./exclusivecoind getinfo

#list of masternodes has various levels
./exclusivecoind masternode list

./exclusivecoind masternode list full

to specifically check an IP
./exclusivecoind masternode list full particularIPaddress

you can also filter the output using grep for any information eg transaction
./exclusivecoind masternode list | grep transactionID

#to get list of possible useful commands
./exclusivecoind help



--
possible issues,
--

if not successful you might have port issues, ensure your port is open by entering
netstat -ntlp | grep yourport#

if you get no output, it's not open
have you installed a firewall?

--
nano is a text editor, it might need to be installed
it's far more noob friendly than vim.

apt-get install nano

--
possibly default editor is already vim (or other), so to open use

EDITOR=nano crontab -e

manage files download from developer.apple.com

Downloading large files from Apple sucks. Here's how to apparently download using terminal with resume option ....



How to download files from Apple Developer Center:

  1. Open Terminal
  2. run gem install adcdownload
  3. Open https://developer.apple.com/down... and copy the URL of a file.
  4. run adcdownload get http://adcdownload.apple.com/…/file.dmg
  5. You will be asked for your Apple ID and password.
  6. Your download should start. If your connection drops, re-run the same command to continue the download.

How to setup an Exclusive Coin master node.


please note this post has changed from it's original content, 
if you used the original version you should go through this guide again and if necessary reconfigure your masternode.




There are two basic methodologies to run masternodes,
1. entirely on one wallet, 

this requires the running wallet to have the coins in the wallet and does pose some risk, 
but no more than a general staking wallet.

the risk is that if someone gains access to your machine, they have theoretical access to all sorts of information including your running client and your wallet.

it is important to note that there are a multiplicity of coins that require a consistently online hot wallet for staking, 
if you are staking Exclusive coin you are equally as vulnerable as if you running a properly setup masternode from a hotwallet.
You are also at risk if you have any form of wallet with funds in it that can access the network,
because hackers.

2. using a two wallet setup as a hot/cold setup 

this requires you have one hot wallet setup as our guide suggests (with direct access to funds), and another cold wallet setup differently (with no access to funds).

the hot wallet first registers the node, then the cold wallet will piggyback off that registration and run a masternode.

this setup can be used to start multiple remote masternodes.

this is more secure because even if someone gains access to the machine running the masternode, there are no funds at risk.
again we'd like to point out the simple fact that all staking wallets are hot wallets and are theoretically at risk.


1. entirely on one wallet, 

1. send 5000 EXCL to address,
2. modify exclusivecoin.conf,
3. modify masternode.conf,
4. start master node.
5. confirm success


There is at least one instance in old versions of the Qt that mentions sending 10,000 coins for master node, this is incorrect. You only need 5,000 (at the moment, this may change).


1. send 5000 EXCL to address,
go to new wallet and get new address, send exactly 5000 coins to that address in one single transaction, (if you want two master nodes you will use two addresses etc ..)


2. modify exclusivecoin.conf,
here's the contents of my final exclusivecoin.conf,

rpcallowip=127.*.*.*:*
rpcuser=whatever(make something up)
rpcpassword=whatever(make something up)
server=1
daemon=1
listen=0
masternode=1
masternodeprivkey=6QXGyLgjLYQQad6WXNDuAtnEKNciSJYdxp7doirPoy6PafVBwpF
masternodeaddr=180.216.153.36:23230

there are four things in your exclusivecoin.conf that will differ from mine

rpcuser
rpcpassword these will give remote access to your wallet, so make them a strong user/password pair

masternodeprivkey will be generated in your wallet/debug console,

go to the "Help" menu, and select "Debug window",
this windows gives various information on your wallet, for now we require the middle "Console" tab,
here we can enter commands (via the command line) to the wallet-qt, (this is very similar to how you would interact with the exclusivecoind daemon which has no GUI),

while we are here we will also check our transaction is valid (will need a minimum age of 10 confirmations before it shows),
so enter
>masternode outputs

then
>masternode genkey

copy/paste the "masternode genkey" output into your exclusivecoin.conf against the masternodeprivkey entry, you will also use it in the next step/section.
the "masternode outputs" output shows your transaction is good, and the data will be used in the next step/section.

you should see something like this



masternodeaddr is the ip address and port of the masternode wallet.
if you are running the wallet at home, it is your home address, there are multiple ways to get your ip.

in the debug console enter
>getinfo

this may show your ip address,
alternatively enter "whatsmyip" into google,
this will also show your ip.

for now we will assume standard port number is valid so you will use port number 23230
assuming my ip is 180.216.153.36 then i will enter 180.216.153.36:23230 as earlier


3. modify masternode.conf,
here's the contents of my final masternode.conf,

masternodeEXAMPLE 180.216.153.36:23230 82b7be68fea1877a41105866f0143d88480212688892eda6f9f5609950a98777 0

there are two ways to enter information,
one is via direct editing of the masternode.conf file,
the second is using the masternode tab in the exclusivecoin-qt,

this guide will use the second.

now get necessary information
for your setup you will need this data
alias address:port privkey txid position

alias is just a name for that master node, it can be anything
address:port is yr wallets ip and a port, (each master node must have different ports)
privkey is the output from "masternode genkey" earlier, it is not related to the address you sent 5k to, each mn must have different privkey input
txid and position once you've sent the funds, is the output from "masternode outputs" earlier.

alias make up a name for you masternode, i will use "masternodeEXAMPLE"

address:port this is the same as your masternodeaddr entered into the exclusivecoin.conf
in this case 180.216.153.36:23230

privkey is the output from "masternode genkey" from earlier,
in this case 6QXGyLgjLYQQad6WXNDuAtnEKNciSJYdxp7doirPoy6PafVBwpF

txid and position are from the earlier outputs of "masternode outputs",
you will see something like this

{
    "82b7be68fea1877a41105866f0143d88480212688892eda6f9f5609950a98777" : "0"
}

the long number is the txid and the short number is position,
your txid will be different, your position may or may not be different.


now go to master node tab in Qt, and press create, enter your details and press OK.






















In your data directory there is now a file called masternode.conf
It holds the data you just entered, it will look something like below.



4. start master node.

You will need to re-start your wallet, it will then read the data from your newly edited exclusivecoin.conf and masternode.conf

once re-started,
go to your masternode tab,
if you now press Start or Start All this will broadcast and register your masternode details.

as soon as the wallet starts running, it will be checking the exclusivecoin.conf information against registered masternodes,
now you've broadcast the registration details your masternode should now start running.


WOOT. things should be running now,
but, how to check if they're running?

the most straightforward check is to get the list of running masternodes and check you are entered,
once more to the debug/console and (using your ip not mine) enter
>masternode list full 180.216.153.36
{
    "82b7be68fea1877a41105866f0143d88480212688892eda6f9f5609950a98777-0" : "   ENABLED 61404 Ec52sButeWS2a6niZW3bBwBzsHR1QxLjcB 180.216.142.159:23230 1500345066      150 1500345096"
}

you will see various informations in that output
82b7be68fea1877a41105866f0143d88480212688892eda6f9f5609950a98777-0" is your txid/position
Ec52sButeWS2a6niZW3bBwBzsHR1QxLjcB is your public key holding the coins and tx
you will also see your IP

ENABLED is a good sign ;)
and 150 is your masternode rating, if it is 0 or 1, that is not a good sign, keep an eye on it for a few minutes and if it does not change then go through your data and restart.

in this case the final number 1500345096 is a time stamp and will update every time you enter.



2. using a two wallet setup as a hot/cold setup 
the basic understanding is you don't need to hold the funds in your masternode wallet,
once you register the masternode in your hot wallet, a cold wallet (with no funds) with correct details in the exclusivecoin.conf should now be capable of automatically running the masternode.

the cold wallet does not require any information in a masternode.conf file, this is purely for the hot wallet.

NOTE when running a remote cold wallet, the IP address used will be that of the remote wallet. not the IP address of the hot wallet.

for now the simple explanation is,
steps 1, 3 from above will be done for the hot wallet

the hot wallet will hold the funds, transaction, and masternode.conf details

and step 2 from above will be done for the cold wallet.

the cold wallet will hold the exclusivecoin.conf details


in a wallet containing zero funds you will edit the exclusivecoin.conf with the same
masternodeprivkey
masternodeaddr
details as your hot wallet masternode.conf above


step 4 will also be done from the hot wallet

once you register the masternode via "Start" or "Start All", the details will be broadcast,
when the cold wallet receives the details it should start running immediately

step 5 can be done from either wallet

although given they have different network connections there may be some variations, but over time they should


more infos
coming soon,



notes
If you have multiple nodes then each will have their own separate line of data.
Importantly, each seperate node needs seperate port, excl address, tx.

It's worth noting that "masternode outputs" will give a list in any order without any obvious linkage to address, you'll have to work out which tx goes with which address/privkey






2017-07-18 02:28:38 CActiveMasternode::EnableHotColdMasterNode() - Enabled! You may shut down the cold daemon.

managing the game wallet


it has just occurred to me the simple way to manage the game wallet.
(this is the bumba game where coins are regularly deposited into a publicly shared address)
every time the game address is updated, there is no need to keep that address, nor any wallet with that address.
the idea is, you have an address that you constantly send your coins to, and once you are in the game wallet you can send those coins there.
when the address is updated, delete the game wallet.dat and re-open with a fresh wallet. import the new privkey

however if you want to stake, then you will need to keep the wallet with your coins in it open.

REMEMBER all your coins are in these wallets. back them up and keep them safe.

...                                      
...                                      
simple version ...
one - generate a personal address
two - send coins to that personal address
three - create a new game wallet




          
making sure your wallet-qt is stopped.
go to your datadir and rename (or move) the current wallet.dat,
if there are no files called wallet.dat, the wallet-qt will create a brand new file on start up.

start up the wallet-qt, this will generate a brand new key pool which lives in the wallet.dat file,
get a new recieve address. copy this address somewhere handy so you can refer to it in a minute.
optionally dump the private key associated with this address for extra safe keeping.
          
stop the wallet-qt, go to your data directory.
the new wallet.dat is your new personal wallet. rename it to something obvious (eg wallet.datPERSONAL) and optionally back up externally.
     
rename the previously backed up wallet.dat and restart. this should now start with your previous transactions.
move all the coins to your new personal address.
          
shutdown the wallet-qt
rename (or delete) the now defunct wallet.dat
restart the wallet-qt (with another brand newly created wallet.dat file)
import the current game private key.

                              
                              
now whenever the game address is changed, you can now rename (or delete) the current game wallet.dat, create a new one, and import the new private key.
repeat everytime the address updates.


if you want to stake with this process.
whenever you create a brand new wallet, you can import both the game key AND your personal key, then your coins will be available to stake, and the game coins will show as well.

however you will need to use coincontrol to manage sending the game coins as otherwise you may just send your private coins.


                                       
                                       
                                       

note: when you boot off a wallet.dat backup. it can take a few minutes as it needs to scan the blockchain for address history.
an alternative option is to use a similar process of renaming with the entire data directory. you would duplicate the bumbacoin2 folder and then manipulate it's name and the internal wallet.dat.

the shortcomings of this process is an old backup of your data directory will need to sync the blockchain before it can be used.
also depending on the blockchain this folder can be a gigabyte or more each time.

i will dedicate a future post to this process.

Cleaning up your wallet-qt when it clogs with transactions.

how to clean yr wallet-qt


you data directory holds a complete copy of the block chain, and your wallet-qt holds every single transaction that has taken place for each address you "own".
these competition addresses have been subject to an awful lot of transactions :D

it can be useful to create a clean slate now and then. to much information can clog your wallet-qt.


the above wallet was becoming very sluggish.

things to know - all your private/public keys are stored in a file called "wallet.dat", this file is in your data directory.

to help manage your addresses, you can have multiple wallets with different addresses. this is done by having multiple wallet.dat files, then you can switch between them as you desire.



here is a picture of my macintosh data directory, in it you can see a wallet.dat and a wallet.datBAK. I swap wallets by renaming the files, it's also possible to keep wallet.dat's elsewhere and move them as you will.

to swap it's necessary to STOP your wallet-qt, before swapping.

DONT FORGET these files hold your access to all your coins. if you break them, you could lose all your coins. so keep backups of either the wallet.dat files, or the privkeys or both.

           

which leads back to HOW TO CLEAN YOUR WALLET. this is simply done transferring all desired coins to a new empty address.


TL/DR           
step 1. generate a new address
step 2. dump private key
step 3. send coins to new address
step 4. quit wallet
step 5. rename wallet.dat to wallet.bak (or whatever)
step 6. restart wallet
step 7. import private key from step 2

INDEPTH VERSION           


step 1. go to receive coins, press New Address button, the above dialog will popup, here you can name the address, then when you press ok it will display a new address.
copy this new address
eg B8QX8peKA9LvDb4Ya5GaMWwwLQoukV2aRY



step 2. go to Help/Debug window/console, type in:
> dumpprivkey B8QX8peKA9LvDb4Ya5GaMWwwLQoukV2aRY

 step 3. go to send coins, send them.
this shot is using Coin Control to help specify which coins. this is not strictly necessary in this scenario but it maybe useful.
to access Coin Control, go to Preferences/Display, tick "Display coin control".

step 4. quit wallet


step 5. rename wallet.dat -> wallet.bak
i am using wallet.datBAK02, you can use whatever you want

in this case there is no actual need to worry about the lack of wallet.dat file as the wallet will create one with new keys on startup.

step 6. restart wallet.


there will now be a new wallet.dat file in your data directory.


you will have no transaction data

step 7. go to debug console, type in:
>importprivkey Pe69Ten35qDWqc5cHbGEZfG5bq9npRtY8WkjXAvfGGaJiUQMFo63 newaddress 
it will hang for a moment. 
above i have named the imported key, that is not necessary, but it maybe useful for neatness.


then when it finishes your new wallet should have all the coins

--

OR 

send your coins to an external site, such as cyptobetfair.com or an exchange (when bumbacoin is on one)

step 1. go to an external site, and get a deposit address
step 2. dump private key
step 3. send coins to new address
step 4. quit wallet
step 5. rename wallet.dat to wallet.bak (or whatever)
step 6. restart wallet
step 7. import private key from step 2
