Danke schön Gerd! 
unfortunably my check_mk is crashed 
when I updated to the last version, before I was step-by-step upgrading firmware and version, everything was fine.
Now I had a lot of work to get SHH login running and find this error when starting via omd:
Starting cmc…Failed (Config /omd/sites/SMS/var/check_mk/core/config.pb missing, run “cmk -U” and try again)
The config.pb is really missing and I do not know what to do with the run “cmk -U”
