Debian based OS

You need to config /etc/network/interfaces file.

  • First, debian has not sudo command, so let install:

    su
    apt-get install sudo
    adduser username sudo
    
  • Second, we add our username on the file /etc/sudoers:

    su
    nano /etc/sudoers
    
  • Third, add the following line:

    usernamehere  ALL=(ALL:ALL) ALL
    
  • Four, installing components (the last command, in some cases is not necessary):

    sudo apt-get update
    sudo apt-get install lsb-core htop
    sudo cp /sbin/ifconfig /usr/local/bin/
    
  • Configure the network interfaces:

    sudo nano /etc/network/interfaces
    
  • Add or modify:

    auto eth0
    iface eth0 inet static
    address 192.168.100.133
    netmask 255.255.255.0
    network 192.168.100.0
    gateway 192.168.100.1
    broadcast 192.168.100.255
    dns-nameservers 8.8.8.8 8.8.4.4
    
  • Restart the services:

    sudo /etc/init.d/networking restart
    sudo systemctl start sshd.service
    
  • Now, we connect from the OS host through ssh:

    ssh jenazad@192.168.100.133
    

Red Hat Enterprise Linux based OS

You need to config /etc/sysconfig/network-scripts/ifcfg-* files, each one per driver.

  • First, installing components:

    sudo yum update
    sudo yum install redhat-lsb-core wget epel-release net-tools nano htop
    
  • Configure the network interfaces:

    sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0
    
  • Add or modify:

    BOOTPROTO=static
    ONBOOT=yes
    IPADDR=192.168.100.129
    NETMASK=255.255.255.0
    NETWORK=192.168.100.0
    GATEWAY=192.168.100.1
    BROADCAST=192.168.100.255
    DNS1=8.8.8.8
    DNS2=8.8.4.4
    
  • Restart the services:

    sudo systemctl restart network
    sudo systemctl start sshd.service
    
  • Now, we connect from the OS host through ssh:

    ssh jenazad@192.168.100.129
