3) What I expected to happen is when I attempt to allow WINE to bind to 127.0.0.1:895 via:

authbind wine C:\\Program\ Files\\Hotspot\ Shield\\bin\\openvpntray.exe 127.0.0.1/32:895,895
authbind wine HSS-1.49-install-anchorfree-243-ask3.exe 127.0.0.1/32:895,895

it would do so successfully.

4) What happens instead is that the program run by WINE does not bind to the address & port above. As well, I had gufw running allowing 127.0.0.1:895 in all directions, TCP & UDP (please see attached screenshot.txt).

Hi ruisivi, thank you for filing this bug report and working with us to help make Ubuntu better!

authbind works by setting LD_PRELOAD, and wine does not work well with LD_PRELOAD, as they have to do a lot of syscall/library trickery to make windows calls work in Linux.

This thread explains a lot of it:

http://marc.info/?l=klik-devel&m=119542615603762&w=2

Given the incompatible designs of the two systems, I don't think authbind and wine will ever work correctly together, and I have to mark this as Invalid as well.

Changed in authbind (Ubuntu):
status:	New → Invalid

Clint:

Based on what I read for the thread you posted, while the LD_PRELOAD is theoretically possible to implement in WINE it would require a large re-write of WINE. While this is possible, it's highly unlikely due to it requiring a large re-write of WINE. Hence, it seems the "Won't Fix" status is more appropriate than "Invalid".

rusivi, I see your point completely.

The invalid bug task is reported against authbind, not wine. authbind can't be rewritten another way and doesn't suffer from any sort of behavior that isn't consistent with its fundamental, documented design and operation. Wine simply is not compatible with LD_PRELOAD.

Adding a "Won't Fix, Wishlist" task to Wine to make sure it is associated and seen in Wine's complete bug list.
