    What are eUKhost's policies re blocking ports?

    I have two accounts on different shared servers.

    A check on common ports on one give
    PORT STATE SERVICE VERSION
    21/tcp open ftp PureFTPd
    26/tcp open smtp Exim smtpd 4.69
    53/tcp open domain ISC BIND Named
    80/tcp open http Apache httpd
    110/tcp open pop3 Courier pop3d
    143/tcp open imap Courier Imapd (released 200
    443/tcp open ssl/http Apache httpd
    465/tcp open ssl/smtp Exim smtpd 4.69
    993/tcp open ssl/imap Courier Imapd (released 200
    995/tcp open ssl/pop3 Courier pop3d
    3306/tcp open mysql MySQL 5.0.81-community
    3333/tcp open dec-notes ?
    The same check on the other has rather more ports
    PORT STATE SERVICE VERSION
    1/tcp open tcpwrapped
    21/tcp open ftp PureFTPd
    26/tcp open smtp Exim smtpd 4.69
    53/tcp open domain ISC BIND Named
    80/tcp open http Apache httpd
    110/tcp open pop3-proxy AVG pop3 proxy 9.0.663/9.0.698
    111/tcp open tcpwrapped
    143/tcp open imap Courier Imapd (released 200
    443/tcp open ssl/http Apache httpd
    465/tcp open ssl/smtp Exim smtpd 4.69
    993/tcp open ssl/imap Courier Imapd (released 200
    995/tcp open ssl/pop3 Courier pop3d
    3306/tcp open mysql MySQL 5.0.81-community
    3333/tcp open dec-notes?
    8009/tcp open ajp13?
    8080/tcp open http Apache Tomcat/Coyote JSP engine 1.1
    8443/tcp open ssl/https-alt ?
    If one server has a more limited set, why haven't they both?

    I guess there are applications which need to remotely access a MySQL server but does port 3306 need to be open by default? (I'm glad I use cPanel's password generator to create a 12 chara random password!)

    What are ports 111, 333 and 8009? Do they need to be open?
