Thanx mate! Using ROOTCMD I succeeded in running the SSH daemon. I've posted the instructions at both the naswebsite (http://naswebsite.com/wiki/Category_talk:Thecus_N0204
) and thecusforum.eu. I tried also at the hexus forum were you suggested I use ROOTCMD, but for some reason I can no longer post there.... Unfortunately I'm extremely short of time right now, but I hope to help more in 20 days!
Thank you again!!
P.S. I did it on my N0204 with the latest firmware, so I guess it should work also for you N2200 (pretty much the same beast)
