Where are you doing your scan from?  Another instance in the same cloud?
When you do a netstat -aln from your instance, do you see that it is
listening on 443?

Best,

[ubuntu-cloud] Port discrepancy from Security Group specifications

[Runa A. Sandvik]

Hi,

The Security Group linked to my Ubuntu Precise instance (ami-ac9943c5)
opens ports 22 (ssh) and 443 (https). However, when I scan the server
for open/closed ports, I see 22 (ssh), 554 (rtsp), and 7070
(realserver) as open, and 443 (https) as closed.

Any idea why I'm seeing two additional ports that are not defined in
the Security Group, and why port 443 is closed?
