At this point, it only displays vanet's context space and is not available for download to other Legion systems. At some point soon we hope to have a web-based graphical user interface available for downloading.
You can fine tune your session on this page, by choosing among the various options:
Once you're ready, click the "Login" box to start.
Once you've successfully logged in, you'll see your home context (or the root context, if you have logged in as a guest). The example below shows the home context space for vanet user spw4s:
The browser displays several pieces of useful information. The top of the screen shows the name of the Legion net, a list of options, and your current context. In this screen shot, you are in vanet and in /home/spw4s.
The left side of the screen shows your location in vanet context space. You can click on any name to see other sections of vanet. If you do not have permission to see a particular part of context space, you will not be able to view the objects or see their contents.
The right side of the screen shows the contents of your current context. The browser display each name contained in the current context in the Name column and its object's type in the Type column. More information about the object can be found in three categories: Basics, Permissions, and Details.
Basics -- attrs, class, and names -- tells you about the object's attributes, its class, and if it has any other context names. Permissions -- acls, change -- lets you see and edit the object's access control list. Details -- info, whereis, ping -- lets you see all the petty details (host, vault, owner, LOID, etc.). Please note that you may not have permission to use all of these options on some objects.
These options help you navigate through context space and work with your objects. Let's look at them one at a time.
To create a new Legion context, you'll use the section marked A in the screen shot. Enter the new path in first field and click the "Create Legion Context" button.
If you are copying a local file object into Legion context space, you'll use the section marked B in the screen shot. Enter the local file's path in the first field or use the "Browse..." button to find the file. Enter the new file object's name in the second field, then hit the
The Status window is a separate window that displays what the browser is currently doing. The Status window displays the time the action started, the user id that the action is running under, and the action itself. The current action is listed on the bottom of the window.
An action can be running a Legion command-line tool, waiting for output, generating data, or running a program. If the browser is running a command-line tool, the status window will show what parameters the tool is using. For example, the screen shot above shows that user spw4s is currently running the legion_ls command-line tool for the context /home. On the command line, the current action would look like this:
$ legion_ls /home
This windows shows actions only for your session.
