How to enable port 5000 on AWS ubuntu [closed]

Answer 1

In addition to @Will's answer, its possible that whichever Ubuntu AMI you're using came with restrictive iptables rules by default. Use:

sudo iptables -L

to list any current rules that exist. Use:

sudo iptables -A INPUT -p tcp --dport 5000 -j ACCEPT

to open the port if necessary.
