How can you test access to IRIS running on 1972 from Linux?

We're looking to create a quick and simple test to see if all firewalls are open on 1972 between a linux based web server VM and a VM running InterSystems IRIS.  Does anyone have any ideas for a quick command that can be run from UNIX console that will provide confirmation that traffic is able to get to 1972 on an IRIS machine?

BTW - I don't think it makes any difference but the IRIS machine is running Windows
