# qbase Masternode Setup Script V1.3 for Ubuntu 16.04 LTS
#
# Script will attempt to autodetect primary public IP address
# and generate masternode private key unless specified in command line
#
# Usage:
# bash qbase-setup.sh [Masternode_Private_Key]
#
# Example 1: Existing genkey created earlier is supplied
# bash qbase-setup.sh 27dSmwq9CabKjo2L3UD1HvgBP3ygbn8HdNmFiGFoVbN1STcsypy
#
# Example 2: Script will generate a new genkey automatically
# bash qbase-setup.sh

Masternode was installed with VPS IP Address: ${YELLOW}$publicip${NC}

Use your mouse to copy the whole string above into the clipboard by
tripple-click + single-click (Dont use Ctrl-C) and then paste it 
into your ${YELLOW}masternode.conf${NC} file and replace:
    ${YELLOW}mn1${NC} - with your desired masternode name (alias)
    ${YELLOW}TxId${NC} - with Transaction Id from masternode outputs
    ${YELLOW}TxIdx${NC} - with Transaction Index (0 or 1)
     Remember to save the masternode.conf and restart the wallet!

To introduce your new masternode to the qbase network, you need to
issue a masternode start command from your wallet, which proves that
the collateral for this node is secured."

echo -e "1) Wait for the node wallet on this VPS to sync with the other nodes
on the network. Eventually the 'IsSynced' status will change
to 'true', which will indicate a comlete sync, although it may take
from several minutes to several hours depending on the network state.
Your initial Masternode Status may read:
    ${YELLOW}Node just started, not yet activated${NC} or
    ${YELLOW}Node  is not in masternode list${NC}, which is normal and expected.

2) Wait at least until 'IsBlockchainSynced' status becomes 'true'.
At this point you can go to your wallet and issue a start
command by either using Debug Console:
    Tools->Debug Console-> enter: ${YELLOW}masternode start-alias mn1${NC}
    where ${YELLOW}mn1${NC} is the name of your masternode (alias)
    as it was entered in the masternode.conf file
    
or by using wallet GUI:
    Masternodes -> Select masternode -> RightClick -> ${YELLOW}start alias${NC}

Once completed step (2), return to this VPS console and wait for the
Masternode Status to change to: 'Masternode successfully started'.
This will indicate that your masternode is fully functional and
you can celebrate this achievement!

Currently your masternode is syncing with the qbase network...

The following screen will display in real-time
the list of peer connections, the status of your masternode,
node synchronization status and additional network and node stats.

Here are some useful commands and tools for masternode troubleshooting:

========================================================================
To view masternode configuration produced by this script in qbase.conf:

${YELLOW}cat ~/.qbasecore/qbase.conf${NC}

Here is your qbase.conf generated by this script:
-------------------------------------------------${YELLOW}"
cat ~/.qbasecore/qbase.conf
echo -e "${NC}-------------------------------------------------

NOTE: To edit qbase.conf, first stop the qbased daemon,
then edit the qbase.conf file and save it in nano: (Ctrl-X + Y + Enter),
then start the qbased daemon back up:

to stop:   ${YELLOW}eden-cli stop${NC}
to edit:   ${YELLOW}nano ~/.qbasecore/qbase.conf${NC}
to start:  ${YELLOW}edend${NC}
========================================================================
To view qbased debug log showing all MN network activity in realtime:

${YELLOW}tail -f ~/.qbasecore/debug.log${NC}
========================================================================
To monitor system resource utilization and running processes:

${YELLOW}htop${NC}
========================================================================
To view the list of peer connections, status of your masternode, 
sync status etc. in real-time, run the nodemon.sh script:

${YELLOW}nodemon.sh${NC}

or just type 'node' and hit <TAB> to autocomplete script name.
========================================================================


Enjoy your Qbase Masternode and thanks for using this setup script!
