Subject: Running PTP (Precision Time Protocol) over Wireguard
Date: Tue, 14 Dec 2021 14:15:17 -0300 [thread overview]
Message-ID: <CACD1g0AfxsGNdO9e-fRLUvONfPJXJnLbzGjQb-s8t+iizXdB6A@mail.gmail.com> (raw)
Hey,
Has anyone ever got PTP (precision time protocol) working with
hardware timestamping over a wireguard VPN?
I need to start linuxptp (http://linuxptp.sourceforge.net/) listening
on a Wireguard virtual network interface, however, it seems that
linuxptp relies on the SO_TIMESTAMPING kernel socket option and the
wireguard virtual interface doesn't support that. Moreover, I need
this working with hardware timestamping, and right now I can't even
get it working with software timestamping.
Would it even be possible to get this working? Anyone got any tips?
Can I somehow make the Wireguard virtual interface mirror the physical
NIC's capabilities?
