SNMP - check_icmp: Failed to obtain ICMP socket: Operation not permitted

CMK version: Checkmk Raw Edition 2.4.0p18
OS version: Synology DockerContainer Manager

Error message: check_icmp: Failed to obtain ICMP socket: Operation not permitted

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)

Hi there,

installed checkmk via docker compose on my Synology box, when adding SMNP hosts, they can access but get displayed as host. Operation not permitted.

Quickly installed it on a Debian VM, there its worked fine.

How to fix this error for docker?

Many thanks in advance
