Cygwin rsync and the Window XP SP2 firewall

[Hans Kratz <kratz at omnicore dot com>]

Hi!

We want to use cygwin rsync to implement an autoupgrade feature for our 
software. For that we implemented a script which connects to an 
anonymous rsync server on the default rsync port (873). This works just 
fine but there is one problem. When rsync is invoked the Windows 
firewall displays a message like this:

"To help protect your computer, Windows Firewall has blocked this 
program from receiving unsolicited information for the Internet or a 
network" (see http://support.microsoft.com/kb/875353/en-us)

Despite this message rsync'ing works just fine.

This message is usually displayed if an application opens a port 
listening for inbound connections on a network interface. Opening a port 
on the loopback interface only does not provoke this behavior.

Now my questions are:
What does rsync do to provoke this message?
How can I prevent this message from being displayed

Version details:
Windows version: XP SP 2 [Version 5.1.2600]
rsync version: rsync  version 2.6.3  protocol version 28
cygwin version (uname -r): 1.5.12(0.116/4/2)


Please cc me as I am not subscribed to the list. Thanks for your help!


Best regards,


Hans
