OpenBSD IPV6 bad behaviour

Open ghost opened this issue 4 months ago • 1 comments

Hi,

I have noticed a strange behaviour with

OpenBSD 7.7
Node Exporter 1.9.1

WHen I start the process like ./node_exporter --web.listen-address="[::]:9090"

It returns as listen address time=2025-08-27T20:10:00.800Z level=INFO source=tls_config.go:350 msg="TLS is disabled." http2=false address=0.0.0.0:9090

It seems to listen only with IPV4

I have tried on Linux (Debian 11) and its OK.

Might be a go issue? This is what starts the listener, we don't do anything special for ipv6: https://github.com/prometheus/exporter-toolkit/blob/8da41e688fd0081e96453a085e90fa3aaaa30fba/web/tls_config.go#L293
