Making your own console server using OpenBSD

Using only base... and serial hardware

Serial lines as consoles are still with us, since a serial port can be used for communication even when all else has failed on the system. I built my own based on an off-hand comment by someone on the OpenBSD lists. I'll walk through how and why I did it along with the history and improvements in my solution.

The talk will walk through my implementation choices and their good points, bad points, and points I shouldn't admit to in public. At the end of this talk, attendees should have a good sense of the issues around building their own console server and be able to avoid some of the pitfalls I came across.

Points of discussion:

  • Choosing hardware: Qualities and trade-offs
  • Advantages to using software in base
  • Driver Issues and other bumps along the way
  • How the console server has changed over the years
  • Advantages over IPMI, iLOM, and others
  • Features you may want
  • Problems others have run across
  • What I'd do differently
