Odhcp6c spams my system log

[eeftychiou]

Any idea how I can get rid of the below warnings?

Tue Mar  8 10:35:10 2022 daemon.warn odhcp6c[2228]: Server returned IA_NA status 'No Address Available (No addresses have been assigned)'
Tue Mar  8 10:35:11 2022 daemon.warn odhcp6c[2228]: Server returned IA_NA status 'No Address Available (No addresses have been assigned)'
Tue Mar  8 10:35:13 2022 daemon.warn odhcp6c[2228]: Server returned IA_NA status 'No Address Available (No addresses have been assigned)'
Tue Mar  8 10:35:14 2022 daemon.warn odhcp6c[2228]: Server returned IA_NA status 'No Address Available (No addresses have been assigned)'

I disabled odhcp6 via UCI

# uci get dhcp.lan.dhcpv6
disabled

Also changed the loglevel to 3 as you can see below.

but still get the warning every 1 second. Here is my config file.

config dnsmasq
        option domainneeded '1'
        option localise_queries '1'
        option rebind_protection '1'
        option rebind_localhost '1'
        option local '/lan/'
        option domain 'lan'
        option expandhosts '1'
        option authoritative '1'
        option readethers '1'
        option leasefile '/tmp/dhcp.leases'
        option resolvfile '/tmp/resolv.conf.d/resolv.conf.auto'
        option localservice '1'
        option ednspacket_max '1232'
        option confdir '/tmp/dnsmasq.d'
        option quietdhcp '1'

config dhcp 'lan'
        option interface 'lan'
        option start '100'
        option limit '150'
        option leasetime '12h'
        option dhcpv4 'server'
        option ra 'server'
        list ra_flags 'none'
        option dhcpv6 'disabled'

config dhcp 'wan'
        option interface 'wan'
        option ignore '1'
        list ra_flags 'none'

config odhcpd 'odhcpd'
        option maindhcp '0'
        option leasefile '/tmp/hosts/odhcpd'
        option leasetrigger '/usr/sbin/odhcpd-update'
        option loglevel '3'

Any help is much appreciated.

Server returned IA_NA status

To get rid of it, turn it on - not off.

I disabled odhcp6 via UCI

Do you really need this disabled, or are you simply trying to stop the log messages?

[solved] Odhcpd warning every ~2 mins - daemon.warn odhcpd: DHCPV6 SOLICIT IA_NA

Hi there, I set up a new router here with recent LEDE and everything works as expected. Only some warnings in the logs are annoying me. Mostly because I can't figure out what they are about. The log reads Mon Nov 6 12:14:22 2017 daemon.warn odhcpd[11272]: DHCPV6 SOLICIT IA_NA from 00030001f0795937acd0 on br-lan: ok fda3:6e4d:4b92:10::29e/128 Mon Nov 6 12:16:17 2017 daemon.warn odhcpd[11272]: DHCPV6 SOLICIT IA_NA from 00030001f0795937acd0 on br-lan: ok fda3:6e4d:4b92:10::29e/128 Mon N…

I essentially want to stop the log messages repeating every 2 seconds in the systemlog. I have no usecase for IPv6 so stoping the service does not harm.
