I am creating the master node according to the instructions on the site.
There is something I don't understand. Please tell me.

Ubuntu 18.04.2 server

Masternode installation

6.Server configuration

  sudo apt-get update && sudo apt-get -y upgrade
  sudo apt-get -y install software-properties-common libzmq3-dev pwgen
  sudo apt-get -y install git libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev
  libboost-all-dev unzip libminiupnpc-dev python-virtualenv
  sudo apt-get -y install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils
  sudo apt-get -y install virtualenv
  sudo add-apt-repository ppa:bitcoin/bitcoin
  sudo apt-get update
  sudo apt-get -y install libdb4.8-dev libdb4.8++-dev
  sudo adduser monoeci

  sudo adduser monoeci sudo
  su monoeci
  cd
  wget https://github.com/monacocoin-net/monoeci-core/releases/download/v0.12.2.3/monoeciCore-0.12.2.3-linux64.tar.gz
  tar xvzf monoeciCore- 0.12.2.3 -linux 64 .tar.gz
                               ↓
  gzip: stdin: not in gzip format
  tar: Child returned status 1
  tar: Error is not recoverable: exiting now

I got a message here. What should I do after this?


Also, if I want to create a master node on my local computer,
Do I have to configure openSSH or FailToBan or Snti RootKit?
