Hi.
I guess this is more like a general Linux question.
How can I find out on my Fedora 25 what port I have to open up for a
program to work?
I recently purchased a Multifunction Canon Printer TS5000 series. They
use a propetary program for scanning images called ScangearMP .
When I execute scangearmp2 it cannot find the printer on the wireless
network.
If I drop the firewall, then scangearmp2 indeed finds the printer.
How can I find out what firewall ports scangear is trying to use? I
tried netstat but the listing I saw was kind of large and did not
immediately make sense to me.
printer: ipp protocol port 631
You have a list of ports and associated devices/protocols in /etc/serveces
