Hi Bruno The mentioned above settings still generate 10-Nov 15:22 bareos-fd: Warning: Cannot open IPv6 stream socket. ERR=Address family not supported by protocol 10-Nov 15:22 bareos-fd: Warning: Can't add default IPv6 address (IPv6 address wanted but IPv6 is disabled!) which broke all automations.

I see /etc/default/grub GRUB_CMDLINE_LINUX=".... ipv6.disable=1 ............." and /proc/cmdline ends with ipv6.disable=1 as well. That means IPv6 is globally disabled at the kernel level. I have to use this OS image and can't get the IPv6 stack back. Can I have the possibility to completely disable ipv6 usage in bareos to avoid these warnings?
