Dear Michael, First, v4 and v6 config file _must_ be different: Probably we should call v6 config as dhcpd6.conf by default.
# use already specified config file or fallback to defaults DHCPDv4_CONF=${DHCPDv4_CONF:-/etc/dhcp/dhcpd.conf} DHCPDv6_CONF=${DHCPDv6_CONF:-/etc/dhcp/dhcpd.conf} The second line should be: DHCPDv6_CONF=${DHCPDv6_CONF:-/etc/dhcp/dhcpd6.conf} Next, there's a typo: DHCPDv4_PID="${DHCPDv4_PID:-/var/run/dhcpd.pid}" DHCPDv6_PID="${DHCPDv4_PID:-/var/run/dhcpd6.pid}" The second line should have: DHCPDv6_PID="${DHCPDv6_PID:-/var/run/dhcpd6.pid}" Thank you. -- Gergely EGERVARY
