The standard GSUtil installation recommended by Google wasn’t working. I found an alternative way to install GSUtil using wget to download, and tar to unzip. You might need to add a path if you install it on a non-standard directory.
Testing a Network Port Connection
You can test a network port connection using the “nc” command on Linux and “telnet” on Windows.
Format:
$ nc -zv domain.com port
C:\> telnet domain.com port
$ nc -zv domain.com 80 Connection to domain.com 80 port [tcp/http] succeeded! |
C:\> telnet -zv domain.com 80 Connecting To domain.com...Could not open connection to the host, on port 80: Connect failed |
For Telnet, if a connection is successful, it returns no message.
