I am not able to connect to my server using FTPS. I noticed that port 990 is not open. When I try to connect to my server on port number 990 I get the following:
telnet myip 990
Connecting To myip...Could not open connection to the host, on port 990: Connect failed
I am able to telnet to the same server on port 21.
How can I open port 990 on my ubuntu server?
The firewall is inactive:
ubuntu@ip: sudo ufw status
Status: inactive
This is what I get for iptables:
ubuntu@ip:sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
This is what I get from apparmor:
ubuntu@ip: sudo aa-status
apparmor module is loaded.
22 profiles are loaded.
20 profiles are in enforce mode.
