Static configurations usually need IP addresses as well as DNS resolvers plus routing. In this tutorial, we will cover Linux static configuration on Ubuntu 16.04. Note: We have three(03) networking interfaces including  loopback(lo) etho0 = ipv4 eth1 = private LAN &  eth2 = ipv6 . Step 1. Edit the /network/interfaces file # vi /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 94.37.87.2XX netmask 255.255.252.0 gateway 94.37.X.1 dns-nameservers 8.8.8.8 8.8.4.4 dns-search datahead.biz auto eth1 iface eth1 inet dhcp auto eth2 iface eth2 inet6 auto Step 2. Restart the networking service (or reboot) Once you are confident the change has been made, and if you don’t want to reboot you can just restart the networking service. # sudo /etc/init.d/networking restart After doing this, and provided you don’t get any errors, your primary network interface should now be configured with the st

A hostname is a label that identifies a machine on the network. You shouldn’t use the same hostname on two different machines on a same network..You might ask yourself why you would need to change your hostname? The most common scenarios would be due to a domain name change, your business has changed its course, or because you have thought of something better. The hostname is used by many of the networking programs (such as sendmail, Apache servers) to identify the machine. By default, your server is started with the server’s given name as the hostname. Some software, such as cPanel, CWP , VestaCP requires a valid Fully Qualified Domain Name (FQDN) for the hostname. Types of hostnames (The hostname can be configured as follows): Static host name assigned by sysadmin. For example, “server1”, “wwwBot2”, or “host.datahead.biz”. Transient/dynamic host name assigned by DHCP or mDNS server at run time. Pretty host name assigned by sysadmin/end-users and it is a free-form UTF8 ho

There are many Open Source Hosting Control Panel comes with predefined firewall. VestaCP uses Iptables+Fail2ban . But sometimes the UFW firewall is the default firewall that ships standard with the Ubuntu Linux Distribution. UFW stands for Uncomplicated Firewall. We are removing ufw because we will use CSF (ConfigServer Security & Firewall :- requires correct iptables configuration on host server) , So We will not remove default IPtables . To enable the ufw firewall, open a new Terminal window and execute the following command: # sudo ufw enable To disable the ufw firewall, open a new Terminal windows and execute the following command: # sudo ufw disable To view the status of the ufw execute the below command: # sudo ufw status To remove UFW completely # sudo apt remove --auto-remove ufw # sudo apt purge ufw # sudo apt purge --auto-remove ufw # sudo apt remove ufw How to remove firewalld from Ubuntu 16.04 (Xenial Xerus)? Uninstall firewalld To remove just firew
