Troubleshooting
With Desktop Transporter being a very network oriented application,
there are many things that can go wrong. A number of common problems,
and their solution, are presented here.
Desktop
Transporter appears to hang when connecting
Desktop Transporter may appear to hang
(as indicated by the spinning rainbow of death) in cases where the
remote host is not
responding. This is typically caused by the remote host running
firewall software, and is most easily solved by opening port 7001. If
your Mac is running the default firewall software, follow these steps
to open up port 7001:
Open
System Preferences
Select
Sharing and click the Firewall tab
If the
firewall isn’t running, the firewall is not the cause of your problems.
Read on below for other possible causes.
To open
port 7001, click New and select Other in the menu that appears.
Enter 7001
in the field for port number, and a description (such as "Desktop
Transporter" or similar)
Click OK,
and make sure that the checkbox for Desktop Transporter is checked in
the list of open ports
Finally,
note that you need to open port 7001 on the computer to which you are trying to connect.
The firewall status of the client Macintosh is of no importance, unless
that Mac is also sharing its display.
NAT
Problems
Another problem is caused by NAT (Network Address Translation), in
cases
where you attempt to connect manually to a remote Macintosh. These
problems are in general difficult to fix without detailed knowledge of
the network infrastructure, and won't be dealt with here.
Finally, if you don’t see shared displays in the list of shared
displays (or not the ones you are interested in), there are a number of
things you can do:
First,
check that the sharing computer is 1) sharing one or more displays, and
2) that it is advertising its displays using Bonjour (the Advertise
displays using Bonjour checkbox should be checked)
If
both of the above conditions are fulfilled, it is possible that the
other Macintosh is on a different subnet, where Bonjour isn’t
getting through. You can solve this by connecting manually to the
remote desktop. To do this, you need to know the hostname or IP-address
of the Macintosh to which you wish to connect, and then enter this
information when selecting Connect to shared desktop... from the
Desktop menu.
Problems
interacting with the remote display In some cases, you may experience problems interacting
with the remote display, either in fullscreen mode or in windowed mode.
First, make sure that the Only observe checkbox is unchecked --
otherwise you will not be able to interact with the remote display at all. Also, ensure that the
computer sharing the display has the "Allow others to interact"
checkbox in the Sharing tab checked.
A common reason for problems or inconsistencies when interacting
with the remote display is that the state of the modifier keys
(command, shift, option and control) has become inconsistent. This
means that the remote computer thinks that, for instance, the command
key is pressed, whereas in reality it isn't. To fix this, simply press
and release, in turn, the modifier keys on your keyboard. This should
return the remote state to normal, allowing you to interact with the
remote display as usual.
