Hello all,
I followed the tutorial on https://www.monetdb.org/Documentation/Cookbooks/SQLrecipes/ClusterManagement
but I still can't get it to work. I followed all instructions, but *monetdb discover *only returns instance(s) running on the same machine, but not others on the network.
I am using three machines running debian, with monetdb installed and configured according to the link above. What am I missing?
Your assistance is highly appreciated.

Make sure they are all in the same network, and that UDP broadcasting is allowed by your firewall configuration.

Hello fabian,
Thank you for your reply.
To make it clearer, I am using three virtual machines from Google Compute. I found this on their site:
*Note:* Google Compute Engine networks only supports point to point IPv4 traffic. Broadcast and Multicast are not supported. (source: https://developers.google.com/compute/docs/networking).
Does this mean there is no other alternative to achieve MonetDB Clustering? Like creating a configuration file.
Your help is appreciated.

Hi Ali,
Unfortunately, with the current software stack, there is no way you can get cluster functionality without UDP broadcasts. What you would need is something like https://www.monetdb.org/bugzilla/show_bug.cgi?id=2498.

Hello Fabian and thank you for replying to my question.
Given I am no C developer, would it be possible to hack the source code somewhere and hard-code the IPs of the servers instead of using UDP discovery? Shouldn't MonetDB store information about the servers somewhere?
Thank you.
