AW: [PATCH] ntpd: Add option -I to ntpd server

[Nikolaus Froehlich]

Hi Harald,

>As a suggestion: Can't we just extend the -l (lowercase letter L) option
for this purpose? If -l is given without further information, >ntpd bind to
all interfaces (the default address), else ntpd binds to the given
Interface/Address. This way we do not introduce a >new option.

>The help text of -l would be "-l [INTERFACE]  listen on port 123 of given
INTERFACE (default all Interfaces)".

By choosing -I as option, I attempted to stay as close as possible to the
ntp.org ntpd reference implementation.  On the other hand, since my
implementation is not 100% compatible to the reference implementation anyway
(as it allows the option to be given only once), we might as well extend the
existing -l option as per your suggestion.

Attached is a reworked patch extending the existing option -l (lowercase
letter L) to allow for an optional parameter INTERFACE specifying the
interface to bind the ntpd server to.

Comments and improvements are very welcome.

Regards, 
                          Nik.
