Backup Cisco config with Rancid and an unprivileged user

RANCID is a tool for backing up network devices configuration and versioning the backups. It was originally intended to backup Cisco configurations it does this by logging in to the devices using either telnet or ssh and then runs a series of commands. In a default set up it runs multiple commands and captures the output of each command, we don’t need all this information infact we only want to store the configuration and so we only need to grant the user one command “show running-config”.
