[Olsr-users] Where am I going wrong in the settings.

[Teco Boot]

So we have two issues.


1. interface up and not running, static routes are still in routing table.
I cannot help you here, I asked someone to assist.
Henning?


2. dyn_gw with ping check doesn’t work.
Long ago I helped Caspar to repair this plugin. I tested, it worked. Let’s see what we can do.
I tested, below my results. It works.
Please verify with same configuration and show your results.
Do you have tcpdump?


Teco




LoadPlugin "olsrd_dyn_gw.so.0.5"
{
  PlParam "HNA"    "0.0.0.0 0.0.0.0"
  PlParam "Ping"   "8.8.8.8"
}

Here the probing traffic:

And the HNA entry:

(spam-protected):~# echo "/hna" | nc 127.0.0.1 2006

Content-type: text/plain

Table: HNA
Destination     Gateway
0.0.0.0/0       172.31.1.1

Now probe to host that is not on the internet.


LoadPlugin "olsrd_dyn_gw.so.0.5"
{
  PlParam "HNA"                            "0.0.0.0 0.0.0.0"
  PlParam "Ping" "11.8.8.8"

}
