j

j is a simple expect script to securely automate the network login of IOS-like and Junos-based networking equipment by leveraging the open-source password manager pass.

Dependencies:

• expect
• pass

Functionality:

• Automatically insert username, password, and enable password during device login
• Password and enable password are stored securely in the pass .password-store
• Add argument --t to specify a telnet host
• Add argument --j to specify a junos host

Todo:

• Add ability to specify alternate port
• Improve error handling
• Add alternative password manager support

Use

Install expect and pass

Arch:

sudo pacman -S expect
sudo pacman -S pass

Debian and Ubuntu:

sudo apt install expect
sudo apt install pass

CentOS:

sudo yum install expect
sudo yum install pass

Adjust variables

Open j in a text editor and add your username and pass descriptors:

set username <your_username>
set password [exec pass show <your_pass_descriptor>]
set enable [exec pass show <your_pass_descriptor>]

Make j executable

chmod +x j

Also, it's best if you moved j to a directory part of PATH.
