Hi, I use same openvpn config for long time but it seems recent updates (base, packages) caused openvpn to segfault after a route add error.
Any help would be appreciated. j. openvpn-2.3.11 OpenBSD 6.0-current (GENERIC.MP) #2421: Mon Sep 5 07:50:28 MDT 2016 ~~~ # openvpn --config /etc/openvpn/ovpn-brq-udp-x86_64.conf Fri Sep 9 09:53:55 2016 OpenVPN 2.3.11 x86_64-unknown-openbsd6.0 [SSL (OpenSSL)] [LZO] [MH] [IPv6] built on Sep 3 2016 Fri Sep 9 09:53:55 2016 library versions: LibreSSL 2.5.0, LZO 2.09 Enter Auth Username:jbelka Enter Auth Password: Fri Sep 9 09:54:09 2016 WARNING: No server certificate verification method has been enabled.
