Security Policy changes on EC2 instance

Hey all, I've been working and researching this for about a week now and I still haven't had any luck. Basically, I have been trying to open port 3306 to allow connections to my MySql server.

i've added the rule into iptables, saved and restarted that i've added the rule into my router.

I am running several instance of Node and all of them run on different ports.

I need a way to be able to kill a particular instance of Node based on the port it is running (kill node instance binded to port n).

From my terminal I can easily do a "fuser -k xxxx/tcp" xxxx being the port.

The thing is, that is because I have the authorisation to do so.

I'm reviewing the security groups on my EC2 Ubuntu instance that runs a public website on LAMP. Presently my ports are as follows:

22 (SSH) 0.0.0.0/0 80 (HTTP) 0.0.0.0/0 443 (HTTPS) 0.0.0.0/0 3306 (MYSQL) 0.0.0.0/0

I'm thinking it should be possible to tighten up a bit on the mysql port as the connections are only made locally. Any insights are welcome.

Here is the scenario, there are multiple EC2 instances behind a load balancer. When traffic dies down, the SCALE_DOWN policy is triggered from a CloudWatch alarm.

I'm on a Linux machine and am trying to replace an Apache2 instance with a Tomcat 6 instance. I shut down the Apache instance by running a kill on the appropriate pid, but when I try to access any pages, I get an error 504 instead of 404. Additionally, when I run the Tomcat 6 instance, I still get the error 504. Requests to port 80 get returned much faster than requests to port 8080.

I am trying to open port 22 so I can do SFTP on my Windows 2008 server (A 1&1 dedicated server.)

The server uses a Packet Filter within Local Security Policy to handle this. I added a rule for port 22 but the port is not open.

I've recently set up an ubuntu server to host my site - I need to open up port 3306 for MySQL access on my server.

I'm currently using shorewall on my server - how can open incoming connections to 3306 in shorewall?

I am new to EC2 (and Tomcat, for that matter), and I am trying to deploy a vanilla Tomcat 7 server to an Ubuntu 12.04.1 EC2 instance and access the default test site over HTTP.

My EC2 instance is running, and the Security Group includes port 80:

My /etc/tomcat7/server.xml config has been edited to listen for HTTP requests on port 80:

0

I have restarted my Tomcat 7 server via sudo service
