Thanks, I have purged the samba just now.
Haha ... Best regards,
P.S I also found
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:538 0.0.0.0:* 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?
