Unable to connect from other computers about scalabrad HOT 5 CLOSED

Hi Jim, can you use the older version for now? That has encryption support
that isn't mergered into pylabrad yet.

Matthew: should we make the default 'optional' until we get everything
supported?

from scalabrad.

@jwenner, as @ejeffrey said, we have not yet merged tls support into
pylabrad. In the meantime you can start the manager with the option
--tls-required=false to allow older clients to connect. We'll need to
enable this for a while until all the clients are updated, including
getting suitable replacements for the Delphi tools.

I'm glad you're trying out the latest stuff. Where are you running this?

from scalabrad.

Thanks! With the --tls-required=false option and scalabrad-0.5.0, I can connect from other computers. However, I still get the INFO messages as in #37 (but not as frequent). I thus followed your advice here and in #37 to downgrade to 0.4.1.

I'm running this on rottmayer (the DAC testing computer in the ADR lab) so that I can figure out the kinks in getting the new LabRAD stuff (w/ Direct Ethernet, Qubit Sequencer, Manager, etc.) running. This is so we can move to current setup on Ivan (Dry DR) as soon as Anthony/Andrew start warming it up (likely early next week). Anything else I should know?

from scalabrad.

Maybe we can make an SSL proxy / wrapper to let the registry editor /
grapher function until the replacements are complete.

from scalabrad.

@jwenner, I don't think there's anything else you need to know, but please keep me in the loop as you're updating Ivan. I think the manager and servers on that fridge are reasonably current, it's the client code that people have been using on that fridge that is going to need a lot of work to bring up to date.
