pyroughtime's Introduction

pyroughtime

An experimental Roughtime client and server implementation in Python 3 using the IETF draft at https://tools.ietf.org/html/draft-ietf-ntp-roughtime-07.

Dependencies

Example

From Python

from pyroughtime import RoughtimeClient, RoughtimeServer
serv, publ = RoughtimeServer.test_server()
cl = RoughtimeClient()
local_reply = cl.query('127.0.0.1', 2002, publ, newver=True)
google_reply = cl.query('roughtime.sandbox.google.com', 2002, 'etPaaIxcBMY1oUeGpwvPMCJMwlRVNxv51KK/tktoJTQ=', newver=False)
serv.stop()
print(local_reply['prettytime'])
print(google_reply['prettytime'])

From console

pyroughtime's Issues

announce pyroughtime on mailing lists

Could you please consider announcing pyroughtime on mailing lists?

Purpose: popularity, feedback, perhaps some bug reports, code review

https://groups.google.com/a/chromium.org/g/proto-roughtime [1]
Posting on https://www.ietf.org/mailman/listinfo/ntp seems also acceptable. [2]

I saw this post but since that was about a new server, I don't think this client got any attention.

[1] https://roughtime.googlesource.com/roughtime

We would be interested in (either privately or via the mailing list):

Expressions of interest relating to sizable clients.
Expressions of interest in running high-availibility servers.
Any external monitoring tools.
Perhaps a time-sync daemon.

[2] https://github.com/cloudflare/roughtime

If you want to use this code and the protocol please join the NTP WG mailing list so that you are aware of the evolution of the protocol and issues that others discover.

We welcome your bug fixes, issues, and improvements to either the protocol or this code. Note that substantive changes to the protocol need to be discussed on the NTP WG mailing list.
