#EPHEMERAL PORTS AWS HOW TO#

If you need to be coached on how to use the internet, this subreddit probably isn't for you yet - brush up on redditquette and come on back! I get that we are passionate about our preferred instructors, but that doesn't justify name-calling. You can disagree on opinions, sure, but do not resort to personal attacks. This goes hand-in-hand with the rule on Redditquette, which is below. While this is not a hard rule, put effort in so it doesn't look like you're just shoehorning your content for clicks. 'Nice job on passing your AWS cert, check out my blog for more tips' takes away the dialogue focus from the subreddit. This rule is specific in reducing blogspam so that the subreddit can be more focused on text-discussion.

Mondays you may promote content, USA hours.

'TEN GREAT WAYS TO BECOME A MASTER CLOUD ARCHITECT' doesn't help anyone. Use your best judgment but again, do not post general AWS news/questions here in /r/AWSCertifications. For example, there is /r/AWS, /r/AmazonWebServices, /r/AWSJobs, etc. There are multiple 'AWS' subreddit types, /r/AWSCertifications is not the only one that exists.

DO NOT POST GENERAL AWS NEWS/QUESTIONS.

Bring in your discussions, questions, opinions, news and comments around AWS certifications areas like prep tips,clarifications,lessons learned. It’s probably best to open the ephemeral ports on the inbound side when you explicitly want to run updates and then close it off otherwise.This subreddit focuses solely on AWS Certifications.

I changed the NACL to ‘Allow’ on the ephemeral-port rule and the command ‘yum update -y’ ran fine. With the NACL, I could not run ‘yum update -y’ on the web-server (I presume because the ephemeral ports were blocked. My webNACL includes SSH, HTTP, HTTPS all set to allow (on inbound), ports 1024-65535 set to Deny (on-inbound) and then the outbound side set to SSH, HTTP, HTTPS, and 1024-65535 set to ALLOW. I am building the VPC right now and have the t2.micro setup in the public subnet.

I also noticed in the documentation (paragraph 3) that 'If an instance in your VPC is the client initiating a request, your network ACL must have an inbound rule to enable traffic destined for the ephemeral ports specific to the type of instance (Amazon Linux, Windows Server 2008, and so on).' Imagine the http-request being sent to a web-server on port 80 saying 'send me the web-content on port 32551.' I take that to be the ephemeral-port on which it wants to receive communications. I notice, as Ryan was going through the documentation that the docs indicated that the client initiating the request specified the ephemeral port.
