# Summary:
# This script is a one stop installing and maintenance script for Dynamic.
# It is used to startup a new VPS. It will download, compile, and maintain the wallet.

# myScrapeAddress: This is the address that the wallet will scrape mining coins to:
# "IF YOU DON'T USE ATTRIBUTES TO PASS IN YOUR VALUES THEN:"
# "CHANGE THE ADDRESS BELOW TO BE THE ONE FOR YOUR WALLET"
myScrapeAddress=D9T2NVLGZEFSw3yc6ye4BenfK7n356wudR
# "CHANGE THE ADDRESS ABOVE TO BE THE ONE FOR YOUR WALLET"
# "CHANGE THE ADDRESS ABOVE TO BE THE ONE FOR YOUR WALLET"

varVersionNumber="2.5.0.0.a"
varVersionDate="August 12, 2021"
varVersion="${varVersionNumber} dynStartupScript.sh ${varVersionDate} Released by LordDarkHelmet"

# The script was tested using on Vultr. Ubuntu 20.04 x64, 1 CPU, 1024 MB ram, 25 GB SSD, 1000 GB bandwidth
# We recommend running Ubuntu 20.04. This is the LTS or Long Term Support version. This OS version is supported in the long run. The next LTS version will be 22.04
# LordDarkHelmet's affiliate link: http://www.vultr.com/?ref=6923885
#
# If you are using Vultr as a VPN service and you run this in as your startup script, then you should see the results in /tmp/firstboot.log
# The script will take some time to run. You can view progress when you first log in by typing in the command:
# tail -f /tmp/firstboot.log

    # When you connect back to your VPS via an SSH client, be sure to change the port to the one you specified in your sshd_config file. While you are more secure because you changed the port and you have a really secure password, an attacker can still find your port and attempt to break your password via a brute force attack. To prevent this you will need a firewall to limit the number of attempts per second, making a brute force attack impossibly long.

All set!
Helpful commands:
\"dynamic-cli getmininginfo\" to check mining and # of blocks synced.
\"dynamicd --daemon\" starts the daemon.
\"dynamic-cli stop\" stops the daemon.
\"dynamic-cli setgenerate true -1\" to start mining.
\"dynamic-cli listaddressgroupings\" to see mined balances.
\"dynamic-cli getblockcount\" gets the current blockcount
\"dynamic-cli gethashespersec\" gets your current hash rate.
\"dynamic-cli help\" for a full list of commands.

You may need to navigate to ${varDynamicBinaries} before you can run the commands.
This command will navigate to ${varDynamicBinaries} the directory
cd ${varDynamicBinaries}

Alternatively, you can put the path (directory) before the command

example: Getting the block count:
sudo ${varDynamicBinaries}dynamic-cli getblockcount"
sudo ${varDynamicBinaries}dynamic-cli getblockcount
echo "
example: Getting the hash rate:
sudo ${varDynamicBinaries}dynamic-cli gethashespersec"
sudo ${varDynamicBinaries}dynamic-cli gethashespersec
echo "* note: hash rate may be 0 if the blockchain has not fully synced yet.
