So I have a 2013 27" iMac and it's connected via a firewire 800 cord and ethernet cord to my airport extreme. I want to know if it can be done (relatively easily) that I can access a PostgreSQL server on iMac imac or the airport extreme from my 13" MBP via an internet connection? This involves a Machine Learning project in python that I have been coding up the last few years and this idea didnt come up in searches on the site, so I am asking. There was this old tutorial that I found but not sure if it is relevant, so thank you in advance if you can point this thread to an existing example of what I'm looking for. Does this also highlight the dual challenge that I might need to stop using the airport as both a time machine and PostgreSQL server? https://forums.macrumors.com/threads/os-x-server-airport-timecapsule.1659908/ Summary TLDR I have connected my iMac and an airport extreme via firewire and ethernet. Currently, they are acting as a time machine with a 4tb HDD upgrade. Can I start and serve a postgresql database on the airport extreme and access it on my MBP from any internet connection. I'm thinking I can but there must be pages of instruction somewhere, just can't find it.
