Thanks, I have purged the samba just now.

Haha ... Best regards,

P.S I also found

tcp        0      0 *               LISTEN
tcp        0      0  *               LISTEN
tcp        0      0   *               LISTEN

631 is for network printer, I am confused why it need LISTEN here, I
only print once or twice each month.

What 538 is for? I googled, but I don't have 	gdomap installed, strange?

Thanks again,
