ASUS Merlin

Requirements​

  • ASUS router running Asuswrt-Merlin firmware
  • Entware installed (required)
  • USB drive (for Entware and b4)

Install Entware​

Entware is required. If it is not installed yet:

  1. Plug a USB drive into the router
  2. Connect over SSH: ssh admin@192.168.1.1
  3. Run amtm
  4. Choose ep to install Entware

Install b4​

After Entware is installed:

curl -fsSL https://raw.githubusercontent.com/DanielLavrushin/b4/main/install.sh | sh

Service control​

/opt/etc/init.d/S99b4 start
/opt/etc/init.d/S99b4 stop
/opt/etc/init.d/S99b4 restart

The service starts automatically on router boot through Entware.

Paths​

WhatWhere
Binary/opt/sbin/b4
Configuration/opt/etc/b4/b4.json
Service/opt/etc/init.d/S99b4

Without Entware​

If Entware is not installed, b4 is placed in /jffs/b4. In that case autostart on boot is not configured - the binary has to be started manually.

The size of /jffs is usually limited to about 60 MB, so a USB drive with Entware is recommended.
