You have selected OpenBSD because this is one of the most secured OS (maybe the most secured :-) ), but people around you ask to go further.

A cron for laptop and non permanent machines.

Posted on 2018-07-11 14:06:00 by Vincent in Open Bsd vdcron

This blog mark the release 0.5.3 of vdcron

OpenVPN on OpenBSD

Posted on 2017-06-05 18:14:00 by Vincent in Open Bsd

I've read several articles concerning the setup of OpenVPN on OpenBSD. But I've decided to post this one because none I've read address the problem coming from the setuid.

Problem, when you close the connection, this user must have the correct rights to set back your networks configuration settings: route, resolv.conf.
