The problem occurred after performing a restore of a previous system backup and starting the restored Checkmk (1.6 or newer) sites. All host checks and ping services went into a critical state.
This error is caused by missing linux capability permissions on the executables that are sending and receiving ICMP packets to check whether or not a host is reachable.
The restore procedure is now setting the correct permissions right after restoring the files from the backup.
In previous CMA versions you can workaround this issue by executing the post-install script manually after restore. This can be done with the following commands:
- cd /omd/versions/[version]
- lib/cma/post-install
You need to replace [version] with your locally installed version. Please note that this needs to be executed once for each Checkmk version.
