Kernel: arplookup 169.254.62.136 failed: host is not on local network



  • I frequently see the message 'kernel: arplookup 169.254.62.136 failed: host is not on local network' in the system log.

    My local network is 192.168.x.x. Why is there a lookup for the IP above?

    Do I have a configuration problem?

    Thanks,
    Jens



  • Some computer on your net is not configured with static IP and can not receive IP through DHCP, so it picks up some 169.254.x.x IP and then sends arp requests. pfSense's kernel receiving this arp requests understands that according to its config it is impossible to have this IP on this interface and reacts with the message in log.
    Do tcpdump, find out mac of this computer, find computer and fix it.
