Sorry some more information: I updated 4 weeks ago opensuse 15.5 to opensuse 15.6 with activated repo OBS:server:monitoring:zabbix. Just now I checked some zabbix pages and noted that all ICMP Pings failed since that time. Within /etc/permissions the configuration for fping is set to: permissions.easy:# fping (bsc#1047921) permissions.easy:/usr/sbin/fping root:root 0755 I had a local file (permission.local) modifying it as: permissions.local:/usr/sbin/fping root:root 4755 THis file I have now reapplied such that it is working.
