How to setup an EC2 Security Group to only allow inbound traffic on a port from the API Gateway only
Background: * EC2 instances hosting a REST API microservice * A Network Load Balancer that fronts the EC2 instances with a port 443 Listener that has an ACM issued Private SSL cert installed on it * I have created a VPC link to that NLB. * Created an instance of the API Gateway and defined a method on it. Everything is working fine. I need help with creating a Security Group rule that only allows inbound traffic from the API Gateway on the EC2 port where the API Microservice is exposed. How can I go about doing that? Will appreciate any help with this issue.
How to download EC2 volume to personal computer
I am trying to download the data within the storage volume attached to my EC2 instance to my local computer. I do not want to store it on AWS any more, nor do I want to continue to pay the charges that are necessary for a snapshot volume. Could someone please assist me in doing this? Many thanks
Is there a way to know if number of Load Balancer's backend changed?
I frequently run below script to get actual IP addresses of ec2 instances working as a Load balancer's backend. ``` TG_ELEMENTS=`aws elbv2 describe-target-health --target-group-arn $TG_ARN --query 'TargetHealthDescriptions[*].Target.Id' --profile $PROFILE` for i in $TG_ELEMENTS ; do aws ec2 describe-instances --instance-id $i --query 'Reservations.Instances.PrivateIpAddress' --profile $PROFILE done ``` Mostly returned TG_ELEMENTS list is the same (scalling is not so frequent). I was wondering if there is a way to do some small query to know if target group / load balancer's backend change, and if so do some extra queries to get these IP address list?
Setting up digest authentication
Hi, I'm trying to configure a HTTP digest auth on ec2. I create username and pwd by htdigest and set up authentication in both .htaccess and /etc/httpd/conf/httpd.conf by the following. <Directory "/var/www/html"> AllowOverride All AuthType Digest AuthName "Digest Auth" AuthDigestDomain /var/www/html/secret/ AuthUserFile "/etc/httpd/conf/.digestpass" Require valid-user </Directory> But no authentication is successfully set up as I reload the /secret page. Am I missing anything? Any help would be appreciated!
EC2 Connection Problem
Earlier this year I switched my RDS database from EC2-Classic to a VPC. While I've been able to read/write to the database through my Localhost connection, I am now in the process of replacing my old EC2 connections (I haven't been hosting a web app, but have used EC2 in the past when I've needed to run long and potentially slow PHP scripts). It took a couple of tries, but I finally created a Linux EC2 instance that went through the VPC and I was able to connect via WinSCP and Putty. I changed the file permissions and transferred my code over. I tried to reconnect via Putty and am getting a "Network error: Connection refused" message. When I try to login to WinSCP, I'm getting a "Network Error Connection to ---- Refused." I tried stopping and restarting my EC2 connection and using the new public IP address and I'm getting the same errors. What do you think changed so that I can no longer access this connection? Should I just try the whole process again from the start?
