![]() I can do this in System Preferences > Network > Advancedunder TCP/IP settings, I want my server’s IP address to be static so that all devices can reliably talk to the server. One problem is, by default the assigned IP address is not static, meaning it can change after something. How do I identify this machine in the network? By its IP address, each machine will have an internal IP address assigned by the router (DHCP server) as soon as the machine is connected to the network. So this server should be accessible only from within the same network.įor better connection speed, I have disabled WiFi and connected this mac to my network via LAN cable (yes it has LAN Port, no need for an adapter, how cool is that). The mac did not become a server yet, I need to connect to this machine remotely from other devices (in the same network only), currently am not planning to expose this server to the outside world. With this and a power source plugged in, this mac should be running forever. ![]() Plus I have turned off Bluetooth and other unnecessary services & notifications. So even after an unexpected restart, the system will continue running. Also, I have enabled this application to start at the system launch. We can create a session with an indefinite time period, meaning the system will not go to sleep indefinitely, which is exactly what I want. But I kept the existing macOS because this is still an experiment, am not sure if I will be using this setup for a long time (if so then I will switch OS) plus I use another Mac for work, so the compatibility for connections and Screen sharing is built-in.Ĭurrently its running macOS High Sierra (that's the last supported OS for this mac) Softwareįor the OS the best practice would be to replace macOS with some Linux distribution which is perfect for a server (you don't need any GUI). Overall this machine is packed with some hardware to handle some load. For more storage, I can always make use of the External Hard drives connected via the USB. So I have removed the optical drive and replaced it with a 1TB HDD (2.5 inches) with the help of an HDD Caddy (it's cheap). I have already replaced the default HDD with 250GB SSD as the boot volumeĪlso, this mac has an optical drive (yea remember it?) which has no use nowadays.it has already been upgraded to 16GB DDR3 RAM.2.0GHz quad-core Intel Core i7 processor, which should be more than enough for my use case.Without it, the interface won't be able to resolve domain names.Let's look at what this mac has, Hardware ![]() If you configured your IP manually then you need to have at least one DNS server configured. If you are using DHCP then your router can take care of DNS for you, and you can clear the settings by actually omitting the IP numbers while executing the same flag, like this: networksetup -setdnsservers Ethernet You can also set fallback DNS servers, like this: networksetup -setdnsservers Ethernet 9.9.9.9 8.8.8.8 1.1.1.1 Networksetup -setdnsservers Wi-Fi 9.9.9.9 Wi-Fi Set The DNS networksetup -setdnsservers Ethernet 8.8.8.8 root $ networksetup -listallnetworkservicesĪn asterisk (*) denotes that a network service is disabled. To list the interfaces (network services) use: networksetup -listallnetworkservices Networksetup -setdnsservers List InterfacesĭNS setting is interface specific, each interface has it's own DNS servers set to it. To set the DNS manually we can use the networksetup command, followed by the -setdnsservers flag, followed by the network service and finally the DNS-IP, like this: While networksetup and scutil have many advanced and complex uses, setting DNS with networksetup is actually quite easier and faster than doing it with scutil. We can change the DNS setting from the command line of macOS by using the networksetup command or the scutil command. DNS is the service that translates fully qualified hostnames into an IP address.
