I'm working to get an Ubuntu VM directly on the mesh with a wifi dongle. I end up with this:

As you can see, it shows my IP addresses, not hostname.

Here's my nameservices config in olsrd.conf:

LoadPlugin "olsrd_nameservice.so.0.3"
{
    PlParam "sighup-pid-file" "/var/run/dnsmasq.pid"
    PlParam "interval" "30"
    PlParam "timeout" "300"
    PlParam "name-change-script" "touch /tmp/namechange"
    PlParam "name" "KD0NRC-M"
    PlParam "service" "http://KD0NRC-M:0/|tcp|NTP"
}

Here's some olsrd output: http://pastebin.com/Pi3z4NeU

Of particular concern are the error messages related to the KD0NRC-M nameservices packets:

Plugin param key:"name" val: "KD0NRC-M"
Plugin param key:"service" val: "http://KD0NRC-M:0/|tcp|NTP"

NAME PLUGIN: decap type=0, len=8, name=KD0NRC-1

Any idea what's going on here? 10.48.191.141 noted in the error is KD0NRC-HOMEGW's IP.

I suspect the problem may be that KD0NRC-M is an unknown host in that it doesn't appear to be the host running 'olsrd' here (KD0NRC-1) nor is it an attached host for which it's advertising.
