Okay,

I tried ~C a few times and my system keeps telling me "command not found."

Ah, you should be hitting it while the yt serve command is going -- i.e., run yt serve, and in that same terminal window while yt serve is running, type "~C".

In the gui I was able to open, I tried loading the data as you suggest with the full path and hitting shift+enter.  A red box pops up around the yt input panel and nothing pops up on the left.  The yt input panel is then unresponsive (I can't type in it anymore).  However, in the terminal where I've set up yt serve, all the text outputs that yt spits out when it loads data are output:

yt : [INFO     ] 2011-04-21 15:19:13,126 Parameters: current_time = 35.8164705155 yt : [INFO     ] 2011-04-21 15:19:13,126 Parameters: domain_dimensions = [128, 128, 128] yt : [INFO     ] 2011-04-21 15:19:13,127 Parameters: domain_left_edge = [ 0.  0.  0.] yt : [INFO     ] 2011-04-21 15:19:13,131 Parameters: domain_right_edge = [ 1.  1.  1.] yt : [INFO     ] 2011-04-21 15:19:13,132 Parameters: cosmological_simulation   = 1 yt : [INFO     ] 2011-04-21 15:19:13,132 Parameters: current_redshift = 7.03540239852 yt : [INFO     ] 2011-04-21 15:19:13,132 Parameters: omega_lambda = 0.726 yt : [INFO     ] 2011-04-21 15:19:13,133 Parameters: omega_matter = 0.274 yt : [INFO     ] 2011-04-21 15:19:13,133 Parameters: hubble_constant = 0.705

This looks like it could be a bug. (That's why reason is still in beta! :) If you hop into IRC or stop by my office we can take a look at this. Thanks for testing this all out while it's still new! -Matt

Hi all,

I'm not sure if this is the right list to send this to, but I think a bunch of knowledgeable people read this one, and hopefully one of you can help me.  I'm trying to use Reason and I'm kind of confused about the ssh tunneling part.  I start up yt serve on a remote machine (ranger) and I'm told to create a ssh tunnel by executing these commands:

~C -L55185:localhost:55185

My local machine doesn't recognize "~C" and I'm not sure what it is either.  I tried creating an ssh tunnel with this:

Ah, so ~C should dump you at an ssh console.  Sometimes it takes a couple tries, but you should just have to type "~C" right in the window and an ssh prompt should come up, that looks like this:

ssh>

Then you would type -L ...

...

 ssh tg803911@ranger.tacc.utexas.edu -L 55185:localhost:55185

As a quick note, the ports change randomly for each instance of reason.  If someone were to know the hostname, port, AND the UUID of your session, they could run as you.  (Not cool. :)

...

I was then able to successfully open the gui in a browser with the url provided, but I am unable to load data (I can view the help though).  In order to do the ssh tunnel properly do I need to install something on my local machine?

It sounds like if you were able to open the GUI, you are already there.  Have you been able to "load" any data in the window?  For instance,

load("/path/to/your/data")

and then hitting shift-enter, to send the command?  When this is done, it should pop up with a new item in the left hand side.

We're still working on the interface, so these comments and issues ARE very useful, particularly if they present stumbling blocks.

Best,

Matt
