Hi there,
i tried to connect to ooo with a named pipe on a linux system:
I started OpenOffice on a Linux System. It listens to a named Pipe.
Now i tried with java to connect to this pipe.
It only functions, if the java application, has been started as the same
systemuser as OpenOffice has been started.
Every other user (also root), can't establish a connection to this pipe.
Is there a solution for this, or are there any permission problems on
my System.
The problem is that the pipe name FOOBAR at the uno-URL level
uno;pipe,name=FOOBAR;urp
is mapped to a Unix file name like
/tmp/OSL_PIPE_<uid>_FOOBAR
that includes the uid. That way, pipes for two different users cannot
interfere (unlike sockets), but two different users cannot talk to one
another, either. A somewhat broken design, I would say.
FWIW: on the system (OSL) level, this happens only if the pipe is passed
a security handle when created.
