Hi all,

I have compiled Zeek 8.0.4 enabling ZeroMQ support under a FreeBSD 15 host (amd64) but zeekctl returns the following errors:

How can I fix this?

Hey @clopmz , thanks a bunch for testing!

This isn’t actually ZeroMQ specific, but happens if `MetricsPort = 0` is set in `zeekctl.cfg` and `node.cfg` uses a standalone cluster configuration. It reproduces here on Linux, too. I’ll fix it in Zeekctl.

The `standalone` mode isn’t really something you’d run in production.

Please switch from a standalone `node.cfg` layout to a multi-process cluster `node.cfg` - the following is from my Linux testing VM (modulo the af\_packet config):

```auto
[manager]
type=manager
host=localhost

[logger-1]
type=logger
host=localhost

[proxy-1]
type=proxy
host=localhost

[proxy-2]
type=proxy
host=localhost

[worker]
type=worker
host=localhost
interface=enp7s0

```

For a production setup with multiple worker processes you’ll want to look into `lb_procs` and `lb_method` for the `[worker]` section. For getting familiar with Zeekctl+Zeek+ZeroMQ (testing if scripts load, checking on warning/error messages), the above should work. Reach out if not.

Hope this helps!

Ok. It works with multi-process cluster config"!! … many thanks @awelzel
