I get to many of these messages..

Sun Feb 26 08:17:47 2017 daemon.notice odhcpd[1011]: Learned about 2003:d2:53f0:xxxx:1549:ad23:5dbf:5487 on br-LAN

Is there a possibilty to adjust the log-level of odhcpd ?
I am searching for a parameter in the dhcp config..

I have solved it, by modifying the script /etc/init.d/odhcpd:

procd_set_param command /usr/sbin/odhcpd -l 4

A better way would be via UCI, but i see no possibility ..

Thank you for your solution.

There is an uci way in the most recent version of odhcpd (2017-02-21) in LEDE master. Originally implemented in odhcpd with https://git.lede-project.org/?p=project/odhcpd.git;a=commitdiff;h=a898ee5458950203d4b2f8fec28c85313c855b91;hp=51c756cfc15c63322df9fdb70d5c701cfb6b9a9f

In practice we need to edit the odhcpd section in /etc/config/dhcp and add a new "loglevel" option that takes 0-7 as the value. 6 is the current verbose default, while 4 is the old default that only displays warnings and errors.

/etc/config/dhcp

config odhcpd 'odhcpd'
        option maindhcp '0'
        option leasefile '/tmp/hosts/odhcpd'
        option leasetrigger '/usr/sbin/odhcpd-update'
        option loglevel '4'

I've changed the loglevel parameter to 4, and I'm still getting the following every 10 seconds in the syslog:

daemon.info odhcpd[1360]: Using a RA lifetime of 0 seconds on br-lan

I've tried with loglevel 8 ... and 1 , same thing ... Ideas?

This seems to make it stop:

uci set dhcp.odhcpd.loglevel=4
uci commit dhcp.odhcpd.loglevel
/etc/init.d/odhcpd restart
