Any throughput comparison to OpenVPN out there?
by Jan Pokorný 04 Jan '18

04 Jan '18

Hello, recently, I've come across this test comparing OpenVPN vs. SSH tunnelling: http://blog.backslasher.net/ssh-openvpn-tunneling.html so natutally, I guess it would be interesting to perform similar test cases in a Kronosnet - OpenVPN duel so that the expectations are set for "VPN on steroids" and perhaps the limitations are identified if the results are too far from "on par". (Just saying, not doing, I wouldn't go too far in tweaking kronosnet for the best results possible, I'm afraid). -- Jan (Poki)

kronosnet v0.9 (aka 1.0 Release Candidate 1) released
by Fabio M. Di Nitto 16 Dec '17

All, We are pleased to announce the second public release candidate of kronosnet v1.0 - which we are calling v0.9 kronosnet (or knet for short) is the new underlying network protocol for Linux HA components (corosync), that features ability to use multiple links between nodes, active/active and active/passive link failover policies, automatic link recovery, FIPS compliant encryption (nss and/or openssl), automatic PMTUd and in general better performances compared to the old network protocol. The source tarballs can be downloaded here: https://www.kronosnet.org/releases/ Upstream resources and contacts: https://kronosnet.org/ https://github.com/kronosnet/kronosnet/ https://ci.kronosnet.org/ https://trello.com/kronosnet (TODO list and activities tracking) https://goo.gl/9ZvkLS (google shared drive with presentations and diagrams) IRC: #kronosnet on Freenode https://lists.kronosnet.org/mailman/listinfo/users https://lists.kronosnet.org/mailman/listinfo/devel https://lists.kronosnet.org/mailman/listinfo/commits Known issues in this release: * Knet will fail to work on Fedora 26 arm when built with clang. This is a known issue with clang compiler that is fixed in more recent versions of clang. * Knet will fail to build with clang on rhel7 + epel version of clang. This is a known issue with clang compiler that is fixed in more recent versions of clang. * Applications performing configuration changes might experience a long waiting time when calling into the knet API. This is a known interaction issue between the PMTUd thread inside knet and external API locking. https://trello.com/c/uPMjKRYy/847-fix-pmtud-locking-with-external-api * Running the knet test suite with valgrind (make check-memcheck) will fail with Debian Experimental glibc due to a known bug in valgrind. * Running the knet test suite with valgrind on FreeBSD is no longer supported. The valgrind version on FreeBSD is too old and generates too many false positives. Also, please refer to build-aux/check.mk on how to use valgrind in combination with knet. Some platforms requires extra options to work properly. Cheers, The knet developer team
