[jcifs] cannot write data to a named pipe

[santo]

Thanx, I got it working !

It was a combination of 2 problems.
First of all, using the loopback interface doesn't work for some reason.
(Maybe I'll have to find out how I can solve this, because the app I'm
writing probably will/may not now
the ip-address of the machine it is running on).

The second one was that I changed the type from PIPE_TYPE_CALL to
PIPE_TYPE_TRANSACT while I was trying to
Get things work.

=> using the real ip-address of the machine and putting the type back to
PIPE_TYPE_TRANSACT solved the problem.
