SUMMARY: Needed to create an AWS IAM Policy to allow a user access to create and delete EBS snapshots. This script also needed to be able to list volumes:

I was getting error “You must specify a region” when running any aws CLI command. The fix: Using the aws command:
|
|
aws configure set region us-east-1 --profile demo |
which will automatically add the following to the file ~/.aws/config:
|
|
[profile demo] region = us-east-1 |
You many simply edit the ~/.aws/config file yourself and append the same thing:
|
|
vi ~/.aws/config [profile demo] region = us-east-1 |

PROBLEM: An element ID that looked like this would fail to match: service = east node = db1-demo.thedomain.com
|
|
<div style="width: 50px; height: 50px; background: #00aa00; color: #000;" id="Div-node-notes-east-db1-demo.thedomain.com">Content to hide and show here</div> <a href="#" onclick="jQuery('#Div-node-notes-'+service+'-'+node.toggle();return false;">Toggle Div</a> |
SOLUTION: Rig any special characters in the complex hostname (:.[],-@) with a backslash in front of them to ensure proper matching:
|
|
<script> var G={}; G.cleanid = function(myid) { return myid.replace( /(:|\.|\[|\]|,|=|@)/g, "\\$1" ); } </script> <div style="width: 50px; height: 50px; background: #00aa00; color: #000;" id="Div-node-notes-east-db1-demo.thedomain.com">Content to hide and show here</div> <a href="#" onclick="jQuery('#Div-node-notes-'+service+'-'+G.cleanid(node).toggle();return false;">Toggle Div</a> |

PROBLEM: Email delivery to Google was failing with a “Service Unavailable” error:
|
|
relay=aspmx.l.google.com. [IPv6:2607:f8b0:400d:c0c::1a], dsn=5.0.0, stat=Service unavailable |
Note that the network address for the destination is shown as IPv6! That is the root cause of the issue: 1. Sendmail is sending mail from the IPv6 address instead of the IPv4 address 2. Google rejects IPv6 senders without proper reverse […]

Solution: “Double Quote” your variables!
