Hi, So, I have a minor setup issue for my automation setup. Here is a brief overview of my setup: Raspberrypi on the scope connected to a powered usb hub. Connected to the hub are a external wifi card (raspberry pi3 wifi is weak), an astromodified Canon 550D, a QHY5L-II for guiding and an EQ6 pro mount. The camera and QHY are connected to an OAG. The QHY5 is also connected to the mounts ST4 port. On the Rasperry Pi 3 I am running xubuntu with INDI server and PHD2 installed. Using realvnc to view phd2. indi server + webserver starts on boot, static ip on external wifi card starts on boot. On my laptop I have EKOS to connect to indi server and phd2 for guiding. I am running phd2 on the raspberrypi to hopefully this will let PHD2 have a more direct (faster) connection to the guide camera. My issue: Their appears to be a disabled install of ufw which has some groups under iptables. I enabled the ufw and enbled the ports 4400, 7642 (PHD2), 8624 (indiweb), 7624(indi) however the guiding suite of Ekos would not connect to PHD2. I disabled ufw and flushed the iptables and tried again with the above ports however the same result. In the end I have opened all the ports to allow the connection to proceed, which is ok for short term but ideally I would want some security. Does anyone know which ports I should open to get indi, indiweb and phd2 to talk nicely to my laptop EKOS version? Anyone else running a similar setup successfully? Can you give me any indications of what pitfalls to avoid? Thanks
