Sometimes we want to know a specific port is open or not.

check 80 port of google.com
$ tcping google.com 80
google.com port 80 open.

check 8080 port of daum.net
$ tcping daum.net 8080
daum.net port 8080 closed.

check 25 port of mta5.am0.yahoodns.net
$ tcping mta5.am0.yahoodns.net 25
mta5.am0.yahoodns.net port 25 open.

If you want to use it on a Mac, install it first.
$ brew install tcping
