New error: DHCPREQUEST field is missing

[binderth (Thomas Binder)]

I’m also getting this error after adding Things:

Thing network:device:handy	 	[ hostname="192.168.xx.xx", port="0", retry="3", timeout="5000", refresh_interval="60000", use_system_ping="false", dhcplisten="true" ]

I’m neither the Network-guy, nor the Linux-pro, but first: is dhcplisten also faster, if I configured my router to give out “static” IPs for my devices?

secondly: Perhaps it’s just a privilege issue, see

Network binding DHCP problem

I can’t get dhcplisten to work and I was just hoping that there is a Linux wiz out there that can help me. I followed the instructions on http://docs.openhab.org/addons/bindings/network/readme.html#permissions I’m running Ubunto 16.04 minimal image on an Ubuntu C1+. Tried $ sudo setcap cap_net_bind_service=+ep `realpath /usr/bin/java` which didn’t work but since $ ls -l /usr/bin/java lrwxrwxrwx 1 root root 22 Dec 18 16:27 /usr/bin/java -> /etc/alternatives/java $ ls -l /etc/alternatives/…

be Aware of ` and ’ !

But for me, this isn’t also the issue, because:

[17:31:47] pi@openHABian2:~$ sudo getcap `realpath /usr/bin/java`
/usr/lib/jvm/java-8-oracle/jre/bin/java = cap_net_admin,cap_net_raw+eip cap_net_bind_service+ep

I also get those:

interesting enough: the intervals of the ERRORs aren’t periodically as you would suspect? (edit: ok, they are sort of, every 10mins, but on two levels?)
