Well, I went ahead and installed the disgusting iTune for testing
iTune runs a lot of useless processes, two of which are the most important, namely iTunes.exe(main application) and mDNSResponder.exe(the one that does the broadcast/multicast).
It works fine, detected my DNS-323 within 1-2 seconds as shown inside the red oval. As you can see, it works for chinese characters for both the folder and the file names.Tried creating my own Korean MP3 and it worked too. Only thing I changed in iTune setting is check "Look for shared libraries" under Sharing preference tab.
Remember it MUST be unicode(UTF-8) encoded tags, and version ID3v2. There's a option in iTune to convert ID3 tag via Reverse Unicode (read iTune help for more info), or you can download third party software to convert the tag to unicode. This is to be done prior of storing mp3 into the NAS.
Here's my comodo firewall settings , windows xp with its internal firewall turned off.
iTunes.exe
-Allow Outgoing HTTP Request , TCP port 80
-Allow Outgoing TCP Requests, Destination 127.0.0.1 Any TCP.
-Allow Outgoing TCP Request to DNS-323 Only, Destination 192.16x.xx.xx , TCP port 3689
-Block and Log All Unmatching Requests, basically blocks everything else and log it
mDNSResponder.exe
-Allow Outgoing DNS Request, UDP port 53
-Allow Outgoing Multicast, UDP port 5353
-Block and Log All Unmatching Requests
Oh well, going to uninstall this iTune junk and go back to using foobar2000.
BTW: Putty don't display Korean Text....Samba and iTunes does though, I wonder why, probably I need to change the font display even after I set Translation to UTF-8.
