Resolution

Generally it depends on what services are running on the server. All the ports which can be used by Parallels Plesk Panel/services are listed below:



#20 ftp-data (TCP)

#21 ftp (TCP)

#22 ssh (TCP)

#25 smtp (TCP)

#53 dns (TCP and UDP)

#80 http (web server and Plesk updater) (TCP)

#106 poppassd (for localhost only) (TCP)

#110 pop3 (TCP)

#113 auth (TCP)

#143 imap (TCP)

#443 https (TCP)

#465 smtps (TCP)

#587 mail message submission (TCP)

#990 ftps (TCP)

#993 imaps (TCP)

#995 pop3s (TCP)

#3306 mysql (TCP)

#5224 (outgoing connections only) plesk-license-update (TCP)

#5432 postgres (TCP)

#8443 plesk-https (TCP)

#8880 plesk-http (TCP)

#9080 tomcat (TCP)



Added since version 9.0:



#11443 sw-cp-serverd (TCP)

#11444 sw-cp-serverd (TCP)



These two ports are used for SSO service when Billing is installed.



Added since version 10.0



#8447 autoinstaller (TCP)

Additional Information

NOTE: none of these services should be denied access in /etc/hosts.deny and if /etc/hosts.deny includes some general access rules, then explicit allowing rules should be put in in /etc/hosts.allow for all ports mentioned (only ports that accept incoming connections).
