Port mapping fails when using DirectCommand
This section describes some considerations that may apply if port mapping fails when a user
attempts DirectCommand access to an SP.
If DirectCommand is invoked by an unprivileged user (such as a regular user on a UNIX-based
system), DirectCommand may not be able to open privileged TCP ports (numbered below
1024). DirectCommand attempts to open the port by adding an offset to any requested port
number that is less than 1024 and by automatically modifying the URL to represent the new
local port. However, if the service provided by an SP can operate only on the original
predetermined TCP port, DirectCommand does not work properly and displays a descriptive
warning. If this occurs, DirectCommand connections may be made to the SP only by
workstation administrators.
