EasySSH revised

Refresher to build a more-friendly ssh generator. Most of the code is seamlessly copied from my old repo

Changelog:

• v2: revised with more better options, verbosity and independed pkg
• v1: simple POC version of easy ssh

How to use it ?

docs on the way, hold your horses… or figure it out on your own ;)

Assumptions

• aws configs{keys, regions} are exported well
• you will help me clean/review it someday in future

  export AWS_ACCESS_KEY=my_aws_keys
  export AWS_ACCESS_KEY_ID="${AWS_ACCESS_KEY}"
  
  export AWS_SECRET_KEY=my_dirty_secrets
  export AWS_SECRET_ACCESS_KEY="${AWS_SECRET_KEY}"
  
  #region
  export EC2_REGION="my_regions-1"
  export AWS_REGION="${EC2_REGION}"
  export EC2_URL="http://ec2.${EC2_REGION}.amazonaws.com"
      

Breakdown

Basic usage is like

   ./easyssh -h                            
     Usage of ./easyssh:
	-end_msg="##END OF GENERATED SSH CONFIG##": custom comment end msg
	-port="22": ssh port to knock
	-start_msg="##START OF GENERATED SSH CONFIG##": custom comment msg at start of generated ssh config
	-username="ubuntu": ssh username to login as

where,

• -end_msg & -start_msg : custom msg to put at start and end of generated config, useful if you have multiple configs
• -username & -port : self explainator; custom username and port

one more dependency

For seamless ssh, bastion is used and the trick is:

Host !my_bastion_host*
  ProxyCommand ssh -W %h:%p my_bastion_host
  User ubuntu
  Port 22
  ForwardAgent yes

where,

• my_bastion_host* : my bastion host i use to ssh to vpc instances

So put/modify somewhere in your `~/.ssh/config`
