<p>I am using nc command in my Linux box like below to check if a port is listening; This displays success message: nc -z 192.168.0.2 9000 This displays 0: echo $? I have combined it in a shell scr.</p> <p>Feb 14, 2018Β Β· "Inverse host lookup failed" simply means that nc wanted to print which host name 10.0.0.10 corresponds to, but couldn't. UNKNOWN is simply what it then prints as the host name..</p> <p>Apr 1, 2016Β Β· I am trying to learn how to read netcdf files using Python in the most easiest/fastest way. I heard that it can be done with 3 lines of code but I really don't know how. I am running the MITgcm.</p>
