NTP for smips

smips devices only have 32mb of ram

its easy to get into memory ram exhaustion

i think in the foreseeable future this devices need to be upgraded to 64mb of ram

With that attitude, Apollo 11 would never have gotten to the Moon LOL. (Coders these days sheesh).

At that time, users were satisfied with UI consisting of a few switches and lights. These days it has to be 4k display with 16M colours, animated changes at 100Hz frame rate and 2 or 4 possible GUI methods. All this costs CPU cycles, storage and memory.

yes im reviving an old thread.. and a use-case where I use NTP server..

we send out a tiny cheap router for teleworker IP sets.. (along with a POE injector) that MT tunnels via L2TP client to the “mother ship”.. NTP wont travel across an L2TP tunnel, so we serve it locally.. the HaP Mini is a perfect device for someone to use at home.. since I cant put the NTP package on we have to send those kind of ugly Hex Lite;s.. I like the little black box wit ha stand.. it looks cool for an end user to receive…

the phones themselves dont have access to the internet just to the tunnel to access the phone system.. and of coruse access to the MT which serves DHCP

Well that is hogwash, NTP will travel perfectly well across any path that routes IP.
Maybe you used NTP “broadcast” or “multicast” mode which would not work with L2TP directly, but when you use the L2TP line to route a subnet to/from the central location you can still use directed broadcast if you wish.
But you get better results when using client/server mode anyway. Just configure a couple of central NTP servers in your clients so they can query them.
