Hi all,
So, I've deployed Tinc in a non normal manor to which has been working
just fine for days up until recent. Here is a description of the network.
There are two VPN host controllers, A and B. All nodes have a separate
connection to A and B. Tinc has been configured to be in 'switch' mode
for both the A cloud and B cloud. On the back end, I have OSPF running
on all nodes and the host controllers which are populated the routes in
the various clouds so that A is the primary route and B is the secondary
route.
The OSPF routes are populating just fine, and tcpdump on all nodes shows
this. The problem is ARP. From the host controller A, I can ping all the
nodes and all the nodes can ping the host controller. Same as B. NONE of
the nodes can ping each other. When I packet dump the Tinc interfaces
across the nodes I see them sending ARP requests ("who has"). No one
sends a response. Sometimes, and now very rarely, a response is sent. If
I static the ARP entries, everything works.
I know Tinc keeps its own ARP tables, and I dabbled with ifconfig
>interfacename< -arp just to see what happens, and of course that
doesn't help.
Does anyone have any ideas as to why ARP isnt working?
Thanks!
