Get telnet and ftp client back on macOS High Sierra

Apple, in their ultimate wisdom, have removed telnet and ftp client on macOS High Sierra.

It is true. You should not use these commands anymore to do unencrypted management on switches.

But …

For a network administrator these commands are extremely important to do debugging and troubleshooting.

Get your telnet back:

First, install Xcode from the App Store.

Then open a terminal and get the ⇒GNU inetutils using curl :

curl -o inetutils-1.9.4.tar.gz

Then compile it yourself:

tar xvzf inetutils-1.9.4.tar.gz
cd inetutils-1.9.4

The next thing would  be

sudo make install

then all clients are  in /usr/local/bin.

Preferably you install only telnet and ftp. make install installs a whole bunch of commands, which do not work as expected afterwards.

To get only telnet and ftp, simply copy the executables.

cd inetutils-1.9.4/telnet
sudo cp telnet /usr/local/bin
cd inetutils-1.9.4/ftp
sudo cp ftp /usr/local/bin


If you require telnet for troubleshooting, ⇒netcat is a perfect alternative.
