This option may appear multiple times. This option also implies not opening other addresses, except wildcard and localhost. This option is deprecated. Please consider using the configuration file interface command, which is more versatile. ... adding the "-I" option for interface specification, e.g., -I xx.xx.xx.xxx \ -I 2001:xx:xxxx:xxx::xxx \ -I 127.0.0.1 \ -I ::1 to the unit file (or init.d) exec string _does_ work. no error, and logs show the daemon is correctly limited to listening on those interfaces. as the docs above state that the "-I" option is *deprecated*, and that the "interface" config file option should be used, reading further, @ http://www.eecis.udel.edu/~mills/ntp/html/miscopt.html#interface ... interface [listen | ignore | drop] [all | ipv4 | ipv6 | wildcard | name | address[/prefixlen]] This command controls which network addresses ntpd opens, and whether input is dropped without processing. The first parameter determines the action for addresses which match the second parameter. That parameter specifies a class of addresses, or a specific interface name, or an address. In the address case, prefixlen determines how many bits must match for this rule to apply. ignore prevents opening matching addresses, drop causes ntpd to open the address and drop all received packets without examination. Multiple interface commands can be used. The last rule which matches a particular address determines the action for it. interface commands are disabled if any -I, --interface, -L, or --novirtualips command-line options are used. If none of those options are used and no interface actions are specified in the configuration file, all available network addresses are opened. The nic command is an alias for interface. ... adding, instead, e.g. interface listen xx.xx.xx.xx interface listen 2001:xx:xxxx:xxx::xxx interface listen 127.0.0.1 interface listen ::1 to the config file does, also, work. no errors, and the daemon listens ONLY on those interfaces specified, as intended, ...
