I am trying to enable somebody to remote SSH into my box. I was able to edit the SSH configuration files and restart the service. However, I could not connect to port 3999 nor could I manipulate the firewall rules. Can somebody post simple instructions on how to open port 3999 on my Morello box? There does not seem to be a driver for IP tables and UFW is not installed. What do I need to install, how can I make this work?
Also, the forum was down for posting yesterday.
Moved to Morello specific forum
No firewall is configured by default so all ports should be opened, you could confirm that by checking that iptables -L reports no rule. Assuming you are using a Morello board (not FVP), maybe something else on your network prevents connecting to port 3999?
iptables -L
