If you’re familiar with compiling from source and you’ve gotten this far, then you’ll almost certainly appreciate Homebrew. Personally, I think using Homebrew is easier, and there are many other great and useful Homebrew packages out there.

When configuring is done, create from source: makeĪnd finally, use make install to complete the installation of inetutils and telnet: sudo make install Now go to the correct directory: cd inetutils-1.9.4

Next you would decompress the tarsal: tar xvzf inetutils-1.9.4.tar.gz

However, as a prerequisite, you still need to install the Mac OS command line tools to accomplish this.įirst, download the latest inetutils package from gnu.org: If you don’t want to use Homebrew for some reason, you can also compile Telnet yourself from inetutils source. Restore Telnet to MacOS Mojave & High Sierra by compiling Telnet from source Note that for this purpose, netcat requires specifying a valid TCP or UDP port number regardless of the host protocol. For example, you can confirm that the connection to the aforementioned ASCII Star Wars server and port 80 is working with the following netcat command string: Simply, connecting to an external IP with ssh would look like this:įor simple testing of network connectivity, or for testing an open / listening port, netcat can often meet the same needs that telnet offers. There are, of course, some alternatives to Telnet, depending on what you need to use telnet for in the first place.įor remote connections, ssh is the new standard as it is secure, and both the ssh server and ssh client are available by default in all modern versions of macOS system software.

The binary telnet is small and weighs only 114kb, so this is a quick, easy task.īy copying that binary telnet to the following location in modern macOS releases, including macOS Mojave 10.14 and macOS High Sierra 10.13.x, telnet can be run on the new system software releases:Īt that point, you can run the ‘telnet’ command as usual.Īnother option that requires more caution is to request the telnet binary from a trusted colleague or friend who uses macOS Sierra or earlier. With Mac OS and Mac OS X versions that include telnet, Telnet can be found in the following location (thus serving as a reference for where to find the binary file in the backups: If you happen to have access to a Mac running an earlier version of MacOS (Sierra or earlier), or if you happen to have an older MacOS system software backupup from Time Machine or otherwise, you can really just copy the old binaries from that computer or backupup to your modern macOS installation, and telnet works fine. Install Telnet in macOS Mojave and High Sierra via older macOS versions or backups You know Telnet works when you’re greeted by Star Wars displayed in ASCII characters (and yes seriously, it’s the full movie).

When the installation is complete, you can run Telnet as usual:Īn easy way to test if Telnet is working properly after installation is to connect to the crazy Star Wars Telnet server, which plays Star Wars in ASCII art:.
