The idea is to connect pairs of systems with 2 serial cables to create a bidirectional link. We would then run a getty over one of the ports on each machine. This would allow us to login to any server if networking breaks.

The following is a list of our servers and how many serial ports they currently have:

  • caffeine (1 header)
  • natural-flavours (1 on-board)
  • artificial-flavours (1 on-board)
  • taurine (1 on-board, 1 virtual)
  • perpugilliam (2 on-board)
  • citric-acid (2 on-board)
  • potassium-citrate (2 on-board)
  • ascorbic-acid (1 on-board)

We would need the following:

  • 3 x Dual PCI Serial Port Card (PCI-2S)
  • 6 x Null-modem/Crossover Serial Cables (CB-NM9FF)

Total: $70.53
