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 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 inetutils from the GNU site:

curl http://ftp.gnu.org/gnu/inetutils/inetutils-1.9.4.tar.gz -o inetutils-1.9.4.tar.gz

Then compile it yourself:

tar xvzfĀ inetutils-1.9.4.tar.gz
cd inetutils-1.9.4
./configure
make
sudo make install

the clients are now 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.
