Generate the symmetric key (32 bytes gives us the 256 bit key):

$ openssl rand 32 -out secret.key

You should only use this key this one time, by the way. If you send something to the recipient at another time, don’t reuse it.

makefile has a very stupid relation with tabs , all actions of every rule are identified by tabs. and No 4 spaces dont make a tab , only a tab makes a tab...

to check i use the command

cat -e -t -v  makefile_name

it shows the presence of tabs with ^I and line endings with $ both are vital to ensure that dependencies end properly and tabs mark the action for the rules so that they are easily identifiable to the make utility.

toddlers / ansible_gitclone_issue_fix
Created Oct 28, 2017
Solution for `git clone` using Ansible for repos with private submodules with github deploy keys
View ansible_gitclone_issue_fix
# Problem:
# If you use git submodules linking two private github repos, you'll need to create a separate deploy key for each.
# Multiple keys are not supported by Ansible, nor does ansible (when running git module) resort to your `.ssh/config` file.
# This means your ansible playbook will hang in this case.
# You can however use the ansible git module to checkout your repo in multiple steps, like this:
- hosts: webserver
You can’t perform that action at this time.
