(This was split off from 10, since serial console access is a different task from LDAP/RADIUS access via SSH.

Assigning to Jonathan, who has a permanent adapter for Chaos to install. Intention is for this ticket to close upon delivery of adapter to Chaos.

In particular, Jonathan will bring 2x adapters (for the management and data switches) and a USB hub (so we can actually plug everything in) to GEC. When i'm back in the office, i'll plug it all in, make sure it all works, then close this.

Just to get this ticket up to speed:

  • Jonathan brought a USB hub to GEC for me to install on our ExoGENI rack.
  • Chris mentioned that something is wrong with the hub's buffering, and he thinks this is causing serial connections attached via the hub to print garbage characters sometimes.
  • Chris asked what brand the USB hub is: i'm looking at it right now, and as far as i can tell, it is totally no-name, i.e. i can't find a name anywhere on it. Jonathan, do you know what it is or where you got it?
  • Regardless, we need to figure out what to do about the USB cabling of the rack. A reminder of that situation again:
    • bbn-hn has only two USB ports on the back
    • because of the way the rack is put together, the USB ports on the front of bbn-hn are entirely inaccessible (it's not just a question of cable length: we would have to remove the front door of the rack or tunnel through metal walls in order to get USB cables from back to front)
    • We need to plug in three things: 8264.bbn.xo's console, the keyboard, and the UPS monitoring cable. If we have the option, we'll plug in 8052.bbn.xo's console, but it's not as important.

I believe that this has been resolved; please correct me if I am wrong.

Sure, that's fine. I had left the ticket open because Chris had some concerns about the USB hub hardware in use in the rack. But i think it's fine with us as long as it's fine with your group.
