When using the Photon Graphical User Interface there is a utility called ‘phditto’ that allows users to
create private sessions of photon on remote nodes within their local area network. The user can see a
graphical representation of the desktop of that node and manipulate the GUI as if it were a local
session. This option is especially helpful when used for technical support or to remotely start
programs because the computer running the session can visually see the desktop and programs
running on the remote node. This also allows computers with limited or exhausted CPU utilization
or memory to use a remote computers resources.
To start phditto on another node.
1. In a QNX shell (pterm window), type phditto -n//2/dev/ph+ and in this case, phditto will
start a photon session on node 2 because of the -n argument and the node specifier.
2. This command will prompt you for a login information before you access the computer.
3. If you wish to join a session already started on a remote node type phditto -n2 and a window
will launch with the remote photon session in it. This session is not private! View and Control
are shared by the remote terminal as well as the node in question. This is very useful when two
parties are looking to collaborate on a project or show information to individuals remotely.
Phditto is a useful tool which also allows the use of an ip address as a location specifier, a modem as a
medium of transport and a number of other features out of the scope of this help file. If you wish to
learn more about the use of phditto we suggest the Photon Help files or type
