Re-install telnet, ftp etc on OSX High Sierra

 

Updated your mac then realised that telnet is missing (when you’re cross legged on a datacentre floor, probably) ?

$ wget https://ftp.gnu.org/gnu/inetutils/inetutils-1.9.4.tar.xz
$ tar -zxvf inetutils-1.9.4.tar.xz 
$ cd inetutils-1.9.4
$ ./configure
$ make
$ sudo make all install

Back to work !
