nmap shows port 21 to be open
I ran the command
nmap localhost
on my Linux Ubuntu machine and got the following output
Other addresses for localhost (not scanned): ::1
rDNS record for 127.0.0.1: localhost.localdomain
Not shown: 983 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
106/tcp open pop3pw
110/tcp open pop3
143/tcp open imap
465/tcp open smtps
587/tcp open submission
783/tcp open spamassassin
993/tcp open imaps
995/tcp open pop3s
3000/tcp open ppp
3306/tcp open mysql
8443/tcp open https-alt
9080/tcp open glrpc
9081/tcp open unknown
I see that port 21 used by ftp and port 783 used by spamassain is open. FTP is unsecure and I wonder why the port is showing to be open. Normally I banned ftp per Plesk and only allowed there fdps. Spamassain grants itselve bin/bash rights. Thats why i see this also with an critical eye. How can I close these open ports?
