Hi,
I am having an issue with dnsmasq on 3 separate interfaces.
This has always worked correctly but somewhere along the way of upgrading to openwrt version 22.x things started to get messy:
In /tmp/hosts/dhcp.* I get all systems in every dhcp file:
dhcp.guest_dns:192.168.178.13 machine1.blabla.guest
dhcp.lan_dns:192.168.178.13 machine1.blabla.lan
dhcp.vpnlan_dns:192.168.178.13 machine1.blabla.vpn
I am probably missing some option in my config, but for the life of me, I can't find it...
what if you'd show your config?
config interface 'lan'
option proto 'static'
option netmask '255.255.255.0'
option ipaddr '192.168.178.252'

if i understand correctly you upgraded from previous version keeping your configuration which is not the recommendation devs made. might worth a shot (after taking backup) to start from scratch.
But i guess your actual problem is that there is no dedicated option dhcphostsfile for each dhsnamsq instance.
thanx for the reply, added the dhcp-hostsfile option to the various configs, but to no avail...
I think I will just reconfigure everything from scratch... (never a bad idea)
did you create the hosts files before (re)started dnsmasq service?
according to code only adds hostfile option if file exists:
config_get hostsfile "$cfg" dhcphostsfile
[ -e "$hostsfile" ] && xappend "--dhcp-hostsfile=$hostsfile"
I think these are created from entries in /etc/config/dhcp:
config host
option mac '00:05:cd:43:54:77'
option leasetime '24h'
option dns '1'
option ip '192.168.178.13'
option name 'x4100'
But then this is the result:
/tmp/hosts/ :
dhcp.guest_dns:192.168.178.13 x4100.blabla.guest
dhcp.lan_dns:192.168.178.13 x4100.blabla.lan
dhcp.vpnlan_dns:192.168.178.13 x4100.blabla.vpn
just found this one:
instance: Dnsmasq instance to which the host section is bound; if not specified the section is valid for all dnsmasq instances.
I'll try that one
and that did it...
Only "problem" is that u can't do this from the gui...
so in /etc/config/dhcp:
config host
option mac '00:05:cd:43:54:77'
option leasetime '24h'
option dns '1'
option ip '192.168.178.13'
option name 'x4100'
**option instance 'lan_dns'**
yes, that is needed. but i assumed as you already used option instance elsewhere, you'd use the same approach for config host too. anyhow, glad you found the solution.
Like mentioned before, this looks like a "new" option which was introduced somewhere along the way...
Thanks for thinking with me!
