Hello!
I am using LEDE 17.01.2 on several TP-LINK routers (1043ND, WDR4900, Archer C7), is working fine,
but i can not get out of this error message: daemon.err odhcp6c[XXXX]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied). Probably is something related to IPv6 multicast adress but i do not know what to do to get off...
This is fill up systems log (about every 2 minutes): Mon Jun 26 07:52:39 2017 daemon.err odhcp6c[2086]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied) Mon Jun 26 07:54:39 2017 daemon.err odhcp6c[2086]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied) Mon Jun 26 07:56:39 2017 daemon.err odhcp6c[2086]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied) Mon Jun 26 07:58:36 2017 daemon.err odhcp6c[2086]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied) Mon Jun 26 08:00:32 2017 daemon.err odhcp6c[2086]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied)
ff02::1:2 is a message sent to all DHCP servers and relay agents on the local network segment (defined in RFC 3315)
Probably a router on the network is not able to respond properly. Changing this is the best solution. An other solution is below.
A solution to get rid of the message is to remove IPV6 from the wan.
This is done by editing the /etc/config/network file. I use nano to do this.
# nano /etc/config/network
Then remove or commend out the following 3 lines:
config interface 'wan6'
option ifname 'eth0.2'
option proto 'dhcpv6'
