[Solved] Journalctl full of NetworkManager errors

Hi,

I just saw that my journalctl is full of NetworkManager like the following:

mars 19 23:44:57 laptop NetworkManager[408]: <error> [1426805097.675083] [rdisc/nm-lndp-rdisc.c:251] send_rs(): (wlp3s0): cannot send router solicitation: -1.

What is it and how to remove them?

Re: [Solved] Journalctl full of NetworkManager errors

If it cannot send a RS then the interface probably does not have a useable IPv6 LL address to bind to.

Some solutions
1) Fix NM
2) Turn off IPv6
3) use something that works, like dhcpcd

Re: [Solved] Journalctl full of NetworkManager errors

True my ipv6 is disabled due to ip6tables blocking all the traffic. So this message is of no arm Thanks
