• Mount Browan SD card to a Linux/MacOS machine.
• Navigate to the root/.ssh directory of the SD card (as root). Example cd /media/sic/0e2c42bf-d359-42fc-b24d-7565e9b5e2d5/root/.ssh
• Open authorized_keys (sudo nano authorized_keys) file, paste your SSH key in the second line.
• Insert SD card back into Miner
• SSH into Merryiot miner with attached SSH public key.
• Windows - Putty Instructions
• Linux/Mac - ssh -p 168 -i /path/to/your/private/key root@miner-ip

How to Keep SSH Access After Updates

• Update Packages sudo apt update
• Install Nano sudo apt install nano
• Navigate to ssh config file sudo nano /etc/ssh/sshd_config
• Change PasswordAuthentication from no to yes. Optional - Change port to 22 if you desire. Save file
• Restart SSH sudo systemctl restart ssh
• Modify file permissions so it is not overwritten by OTA updates sudo chattr +i /etc/ssh/sshd_config
• Set root password. sudo passwd root
• Modify file permissions so it is not overwritten sudo chattr +i /etc/passwd /etc/shadow

How to fix MAC Address

• For some reason, the browan image comes hardcoded with a MAC address different than your machines. To correct this:
  • Note your device MAC address
• Install macchanger sudo apt update && sudo apt-get install macchanger
• Select No to changing MAC automatically
• Create the following file by running sudo nano /etc/network/if-pre-up.d/change_mac_address
  • Paste the following (be sure to change < your:mac:address >):

#!/bin/bash

# Log file path
LOG_FILE="/var/log/change_mac_address.log"

/usr/bin/macchanger -m your:mac:address eth0 >> "$LOG_FILE" 2>&1

# Check the exit status of the macchanger command
if [ $? -ne 0 ]; then
   echo "Failed to change MAC address. See $LOG_FILE for details." >&2
fi

• Save file
• Make script executable sudo chmod +x /etc/network/if-pre-up.d/change_mac_address
• Prevent updates from deleting this fix sudo chattr +i /etc/network/if-pre-up.d/change_mac_address
• Reboot

Force OTA Update

To update to the latest firmware, ensure all of the above has been completed. Then run /usr/local/sbin/gw_ota stable
