Hi,

make sure you configure discovery to run on the _correct_ network interface, e.g. in the config put

discovery_interface = eth0 discovery_address = 224.0.0.7

if you are using the address option make sure it is a multicast address and it is the same for both computers. If you omit the discovery_address parameter it should use the broadcast address.

You can check whether the nodes are broadcasting discovery packets with Wireshark. Discovery packets are UDP datagrams on port 4551.

I think when using static connections there is no need to receive discovery packets, because the dameon just "assumes" statically configured nodes are present, and thus generates the NodeEvents you see.

Hi,

I added tcp convergence layer and routing = epidemic to my conf file.I did not add any static nodes.This was done on two laptops.

Now,when I started both the daemons,I was expecting the NodeEvent log but I did not get any.This means that the two laptops have not discovered each other,correct?

The next time I run both the daemons I add static connections between them in their conf files.Now I see the NodeEvent log and the connection event.What could be the reason for this?How did it give these logs when I added the static nodes?

Does this mean that nodes with static connections to them are discovered as up or down and the others are not?I am kind of confused here.
