Gregory's Server@hailey @s0 One of the best resources that immediately comes to mind is Maciek's talk at netdev 0x16 https://youtu.be/Hs7oRukMuak
The difficult thing about linuxptp is that you need to have quite a bit of knowledge about IEEE1588 or IEEE802.1as to tweak all of knobs correctly. It's a good stack, but not quite user friendly
@hailey @s0 Ah, and one more important thing: until v4 linuxptp released new versions only ever 4 years or so, which is why most distros have terribly old versions with a few annoying bugs. Make sure to use at least v4 (they release bi quarterly starting with v4 afaik, but I don't know how long it will take Debian to pick up the latest versions). Most convenient way is to build from source...
