OpenWrt has grown from a hobbyist project with a few dedicated developers into the premier open source router operating system distribution. Even though OpenWrt runs on millions of devices, there’s never been a conference focusing primarily on OpenWrt. One of my responsibilities as prpl Community Manager was to work with prplwrt PEG and the OpenWrt community to change that.

Co-located with the Embedded Linux Conference Europe, the OpenWrt Summit was a full day of sessions on everything about OpenWrt. Beginning the day were topics appropriate for beginners such as an introductions to OpenWrt itself and the networking subsystem as well as adding an SoC to OpenWrt . Later, more advanced topics discussed different sides of security for OpenWrt and best practices for building a new distribution off of OpenWrt. In total, sixteen talks were jam-packed into a single day. While it was a lot of information, attendees were happy and excited to all be in the same place. Continue reading

However, I am afraid the story is far from over and the worst may still be to come.
