Hi all, I relatively new to MonetDB, but have many year exposure to database enignes. I have 2 x vm's, almost identical with the exception of IP's and host names. both are Ubuntu Server 18.04 LTS. I have installed MonetDB on both VM's and created a db farm and a database on each. When running 'monetdb discover' on any of the VM's it finds nothing. Any help is welcome please.
