Support for addn_hosts in dnsmasq on Orbi RBR50

In looking at your script a little closer, I think I have figured out that you do not actually run this on the Orbi router directly, but instead from a machine on the same network, correct? So, that negates all of my questions.

 

Sorry.

Yes carlovn66 that is correct. I run this script on a Fedora Linux host that is on the same network as the Orbi device.

One note is that with the very latest firmware on the RBS50 and RBR50, the login prompt has changed and that breaks the above expect script which looks for "login:" and "password:". Below is a revised script that accounts for that change:

#!/usr/bin/expect

set addn_hosts "addn-hosts=/mnt/sda1/hosts\naddn-hosts=/tmp/dhcpd_hostlist\n"

set host "192.168.1.1"
set user "admin"
set password "********************"
set timeout 20

spawn telnet $host
expect "telnet account:"
send "$user\n"
expect "telnet password:"
send "$password\n"

send "grep -qF addn-hosts /etc/dnsmasq.conf || (echo \'$addn_hosts\' >> /etc/dnsmasq.conf && echo 'addn-hosts added')\n"
send "pidof dnsmasq\n"
send "kill \$(pidof dnsmasq)\n"
send "/usr/sbin/dnsmasq --except-interface=lo -r /tmp/resolv.conf\n"
send "pidof dnsmasq\n"
