Here is how to assign a static IP address and a different hostname to an existing Debian 10 Buster minimal installation, how to disable the swap, when the server has enough memory for its purpose, and how to configure a second network interface, if this tutorial is executed to create a router between two networks, to distribute internet in your home or Cloud VPS or Dedicated Server with Debian 10 installed. WRITE FOR US. 2 is an ISP router with DHCPD running on it. To do this, the router analyzes incoming packets and redirects them according to the IP address of their destination. When a local network uses a private address range (not routable on the Internet), the gateway needs to implement address masquerading so that the machines on the network can communicate with the outside world. The NetworkManager CLI client, nmcli, simplifies establishing and controlling network connections while integrating tightly with Linux system configuration files and services for maximum flexibility. Run the following for eth0: # /etc/init. Although the methods explained in this article are for the Debian system, most auto bond0 iface bond0 inet static address 10. conf lxc.

Wireless network interface configuration requires a backend, generally wpa_supplicant (often in conjunction with ifupdown and other utilities) or IWD. It is used to set up various aspects of NetworkManager's behavior. Alternatively, (if you are bold) you can listen to the network traffic on the network by running tcpdump -ni eth0 and try to guess your internal network addressing based on the packets your system receives. 4, „Cloud system initialization“).
