OpenVPN Hackathon 2018

This year's hackathon is organized by Andriy Revin and David Sommerseth

We will stick to the format of the previous years, which means attendance is in principle limited to "active developers that are also regularly contributing to #openvpn-devel or the mailing list". We should have enough space in the meeting room for 10-14 devs.

Who is coming?

If you have any questions - please contact Andriy Revin (andriy @


The hackathon will take place from Friday October 5th 2018 to Sunday October 7th.


  1. What features do we want in 2.5? Set the timeline accordingly
    • tls-crypt v2, sitnl, vlan patches, ipv6-only?
  2. Should OpenVPN be a "swiss army knife" or "secure vpn client for dummies"
    • Could the split between OpenVPN 2.x and 3.x reflect these two roles?
  3. MSI packaging
    • Available for testing for tap-windows6, but not yet for OpenVPN 2




Free wifi network is available at the office


There are many options with hotels and Airbnb alternatives in walking distance from the office (5-10 minutes). Most reasonably priced hotels are fairly small and availability is varying a lot, but double check against,, or similar sites to ensure you get a good price.

Some hotels close by (4-8 minutes walk):

Hotel URL Comments
Ibis Styles Lviv Center Most likely one of the bigger ones, small rooms but decent
Swiss Hotel Reasonable hotel when getting good price offers
ANTARES Apart hotel -
Danylo Inn -
