xlogin

xlogin is a tool to login devices and execute series of commands with ease.

Add this line to your application's Gemfile:

gem 'xlogin'

And then execute:

$ bundle

Or install it yourself as:

$ gem install xlogin

Write a firmware template that describe how to manage the device, and store it to ~/.xlogin.d/.
Be aware that the name of the template file should match the hosttype of the device in the inventory file.
Take vyos as an example, template file vyos.rb would be:

prompt(/[$#] (?:\e\[K)?\z/n)

login do |username, password|
  waitfor(/login:\s/)    && puts(username)
  waitfor(/Password:\s/) && puts(password)
  waitfor
end

Some other example templates are in lib/xlogin/templates.
You can just load these built-in templates by adding require "xlogin/template" in your script.

Beside template files, you should have your own inventory file ~/.xloginrc that list all information required to login each devices.

#hosttype	hostname	uri scheme
vyos	'vyos01',	'telnet://vagrant:vagrant@127.0.0.1:2200'
vyos	'vyos02',	'telnet://vagrant:vagrant@127.0.0.1:2201'

Now you can login to the device in your .xloginrc file.

$ xlogin vyos01

And execute multiple operations with just a single command.

$ xlogin 'vyos*' -e 'show configuration command | no-more; exit' -j 2

Some other commandline options are:

$ xlogin -h
xlogin HOST_PATTERN [Options]

    -t, --template PATH              The PATH to the template file or directory.

    -l, --list                       List the inventory.
    -e, --exec COMMAND               Execute commands and quit.
    -E, --env KEY=VAL                Environment variables.
    -j, --jobs NUM                   The NUM of jobs to execute in parallel.
