whatsmyip | Rust crate to find your ip address | TCP library

When creating a Security Group manually via the console, the Source for a rule can be selected as "My IP" which automatically fetches the client browser's IP address as a /32 CIDR.

Is there a way to have a CloudFormation parameter grab the clients IP address as the default when running the CF template from the console?

Use case: I have a bastion host / access host that I build when needed from a CFN template. Each time I build the host I have to visit a 'WhatsMyIP' type site to get my current IP address and copy and paste it into my CFN parameter. As the AWS Console has a way of grabbing the IP automatically and formatting it as a /32 CIDR it would be good if this was available as a function in a CFN template as well.

UPDATE:

So this works as expected if I add the following:

I have to create a tool like (whatsmyip.com) but with special filters or so, I have to implement this code into a html site but don't know how to echo the returned value in html.. Thanks for your help

I have an Linux web server running WHM/cPanel.

This has a page uploaded in the /public_html folder called compression.php This is accessed with http://www.example.com/compression.php

Within cPanel, in 'Optimize Website', the 'Compress All Content' option is selected and the .htaccess file does have a mod_gzip block - see below:

so I'm really new to bash, and basically don't know anything... I tried to make a little alias to view my IP adress, and it works... but when I close the terminal and open another one and type the command in, it just says it's wrong. here's my code

alias whatsmyip="echo $(ifconfig | grep broadcast | awk '{print $2}')"

Please try to make it simple in the comments so even a baby could understand! Thanks in advance!

I have a Virtual Network Gateway setup on my Azure subscription, and a number of VMs which connect to it.

The VN Gateway created a Public IP automatically, and has it listed in the 'Overview' screen. However going onto any website to check my IP (e.g. whatsmyip.org) gives me an entirely different Public IP. Anyone know why this is?

My configuration of the Virtual Network Gateway is very basic with mostly defaults and the VpnGw1 SKU.

Let's say we have a wifi at home. When I google "whatsmyip", it gives me public IP address, which is essentially IP address of my router on the internet.

Now lets say I have two machines (A and B) both hosting a web server. I want to reach to a web-server on my machine 'A' from outside my local network (from some other corner of the world), how I can ping to that specific machine to my network. I understand for outgoing requests from my machine we have NAT, but what about incoming request to a specific machine? How router resolves it?

How I can check that IP(for incoming requests) in my windows/linux machine?

e.g let's say I have a tomcat server running on port 8080 on machine A. Now if I do localhost:8080/home, it displays "Hello World". Now one of my friend in let's say in Europe wants to access "/home" end point. What ip would he use?{IP}:8080/home. Means how he'll identify my machine, as to the internet only router's IP address is visible

I'm trying to connect to Amazon RDS with MySQL workbench, but I keep running into this error:

Your connection attempt failed for user 'admin' from your host to server at database-2.cv15axugkvps.us-east-2.rds.amazonaws.com:3306:
Can't connect to MySQL server on 'database-2.cv15axugkvps.us-east-2.rds.amazonaws.com' (60)

Please: 1 Check that MySQL is running on the server database-2.cv15axugkvps.us-east-2.rds.amazonaws.com

2 Check that MySQL is running on port 3306 (note: 3306 is the default, but this can be changed)

3 Check the admin has rights to connect to database-2.cv15axugkvps.us-east-2.rds.amazonaws.com from your address (MySQL rights define what clients can connect to the server and from which machines)

4 Make sure you are both providing a password if needed and using the correct password for database-2.cv15axugkvps.us-east-2.rds.amazonaws.com connecting from the host address you're connecting from

I know my hostname, port, username, and password are all right. I even created a second database with a new username and password just to be sure I didn't forget the originals.

It looks like this person had a similar problem. They commented:

Okay, I take the blame for this one. I thought port 3306 was open for everywhere, but I had to assign it my IP address to allow traffic.I had to get my IP address (www.whatsmyip.org) and then add that as a 3306 port in my security group. If your IP is 12.34.56.78, choose "MySQL" from the "Create a New Rule" dropdown menu in you Security Group's "Inbound" tab. Then add 12.34.56.78/32 as the Source, click "Add Rule" then click "Apply Rule Changes"

I tried that but had the same problem.
