Using Portal
Starting Portal for the first time brings up a blank network configuration and a dialog
asking what port to use to connect to the SNAP bridge device:
We’ll continue using the SNAPstick module from the previous section, so keep it
connected to the USB port.
Press Connect once the bridge device (SNAPstick) has been detected (this is probably
going to be USB0).
Navigating within Portal
Portal is straightforward to use. However, since it is extremely customizable by the user,
your screen layout may not always match the screen shots in this manual. For that reason
it is important to understand the fundamental concepts used in navigating the Portal GUI.
Pull-down Menus
At the top of the Portal GUI are pull-down menus for File , View , Options , Network , and
Help operations. (These menus are in their standard position at the top of the screen in
Macintosh and Ubuntu versions.)
Clicking on one of these top-level menu choices will pull down a sub-menu of additional
choices. For example, clicking on Network will present a sub-menu from which you
perform actions like Broadcast Ping , Find Nodes… , or New Configuration . Similarly,
clicking on Help will bring up choices for SNAP Reference Manual , Portal Reference
Manual , etc.
The convention is that menu choices ending in “…” usually bring up additional menus or
dialog boxes, and menu choices not ending in “…” cause immediate action to be taken,
with no further prompting.
Tool Bar
Below the pull-down menus is a horizontal Tool Bar from which you can initiate several
actions. Hovering the cursor over each button will display a short “tool-tip” help
message, and clicking on each button will initiate the action displayed by the tool-tip.
Tabbed Windows
The remainder of the Portal GUI is taken up by a changeable collection of tabbed
windows. Each of these windows has a name, which is displayed in the tab for that
window.
Many of the tabbed windows have toolbars of their own, located in the horizontal region
just below their labeled tab.
Portal starts out with an initial set of tabbed windows visible. Sometimes clicking on
certain controls within one tabbed window will open and/or switch to another tabbed
