Sometimes you want to retrieve EC2 insntances' region information.

You can query that information through instance metadata(169.254.169.254).

$ curl --silent http://169.254.169.254/latest/dynamic/instance-identity/document
{
  "privateIp" : "172.31.2.15",
  "instanceId" : "i-12341ee8",
  "billingProducts" : null,
 "instanceType" : "t2.small",

###Single hop tunelling:

ssh -f -N -L 9906:127.0.0.1:3306 [email protected]

where,

-f puts ssh in background
-N makes it not execute a remote command

Installation

Since the original plugin has been developed for Sublime Text 2 we have to install it manually.

Go to https://github.com/fredbenenson/sublime-cypher, download ZIP of the repo, extract the content and rename the folder to ‘Cypher’. You can download the original repo from https://github.com/kollhof/sublime-cypher but Fred Benenson introduced a handy fix for UTF-8 data, which hasn't integrated at the point of this writing.
