hostname ​

  • Default: LiMe-%M4%M5%M6
  • Parametrizable with %Mn
config lime system
    option hostname 'LiMe-%M4%M5%M6'

The hostname of the node

domain ​

  • Type: string
  • Default: thisnode.info
config lime system
    option domain 'thisnode.info'

DNS domain for the L2 cloud it could be something like mycloud.mynetwork.tld

keep_on_upgrade ​

  • Type: string
  • Default: libremesh dropbear minimum-essential /etc/sysupgrade.conf
config lime system
  option keep_on_upgrade 'libremesh dropbear minimum-essential /etc/sysupgrade.conf'

Files defining the list of files and directories to backup when upgrade.
Relative to /lib/upgrade/keep.d if no / defined.

root_password_policy ​

  • Type: DO_NOTHING | RANDOM | SET_SECRET
  • Default: DO_NOTHING
config lime system
    option root_password_policy 'DO_NOTHING'

Determine the lime setting for the root password:

  • DO_NOTHING - leaves the root password empty (you will have to set it manually or through FirstBootWizard).
  • RANDOM - a strong random password will be set if root has no password, use this if your firmware is built with the ssh keys inside.
  • SET_SECRET - the root password will be configured as specified in root_password_secret.

The default option prevent libremesh from overriding manual configuration, e.g. via luci, uci or the lime-app

root_password_secret ​

  • Type: string
  • Default: ''
config lime system
    option root_password_secret ''

Used only when root_password_policy is set to SET_SECRET.
The password hash will be stored in /etc/shadow. Use a strong password with at least 10 numbers and letters, the longer the better!.

openssl passwd -5

You can generate the secret with openssl passwd -1 to be compatible with most openwrt firmwares.
For improved security use openssl passwd -6 for SHA512 (or -5 for SHA256) but be aware that not all firmwares support this.

firstbootwizard_configured ​

  • Type: string
  • Default: false
  • Packages required: first-boot-wizard
config lime system
    option firstbootwizard_configured false

When true the first-boot-wizard will not appear by default.

firstbootwizard_dismissed ​

  • Type: string
  • Default: false
  • Packages required: first-boot-wizard
config lime system
    option firstbootwizard_dismissed false

When true the first-boot-wizard banner will be hidden.
