The deamon answers with currently_logged_on_username on any reqest. And never tells an error :( E.G.: with 100% fake ports: telnet my-pc 113 Trying 172.16.0.110... Connected to my-pc. Escape character is '^]'. 666 , 7777 666 , 7777 : USERID : WIN32 : myname Connection closed by foreign host. I think, on multiuser systems daemon will get wrong info. PS: winxp updated.
