I want to get the behavior of "nc -z host port ; echo $?" with socat, since my network admins have disabled netcat. The purpose is just to test that a TCP connection is open between two servers. How would I go about doing this?

          Since nc -z host port just attempt to connect without sending any data, it should be equivalent to socat /dev/null tcp4:host:port.



          I think this can achieve your expected bahaviour with socat:



          socat /dev/null tcp4:host:port > /dev/null 2>&1 ; echo $?
