As of now, feature with 178 votes is available in Plesk Onyx 17.9 Preview only: https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/17924536-fail2ban-now-supports-ipv6-please-upgrade

It would be awesome to have this feature available on earlier versions of Plesk Onyx without the necessity to wait until Plesk Onyx 17.9 becomes stable.

Currently, logs about create/Remove Directories or Files are only stored in panel.log with debug enabled. A feature for it will be appreciated in order to avoid enable debug into the server and increase server process.

PIWIK is death!
Simple Matomo-plug-in installation without additional configuration for the databases or the host

Implement http://www.wildfly.org/ instead of deprecated Tomcat

Created according to the comment from this article https://support.plesk.com/hc/en-us/articles/360000322173?page=1#comment_360000633734

The suggestion is to implement CLI utilities to enable/disable Plesk debug:

plesk debug -enable
enabled = on
filter.priority = 7
show.util_exec = on
show.util_exec_io = on

plesk debug -enable --sql
The same as previous + show.sql_query = on

plesk debug -disable

Now it is necessary to remember panel.ini path (/usr/local/psa/admin/conf/), copy panel.ini.sample, then edit it manually every time. And the same procedure to disable it.

Please add Mailman support to Let's Encrypt.

Ideally, one could issue either a certificate directly for lists.domain.com or a wildcard certificate for *.domain.com.

Furthermore, a secure connection should be enforceable.

Thanks!

The possibility to setup a replication for MySQL

Add support of TLS 1.3 to Plesk interface's web server. TLS 1.3. improves security.

Hello,

Please add Extenshios API usitlity and method which allows to append string into a file.

Now it is only possible to read from a file and overwrite a file:

phpPgAdmin support was dropped starting from Plesk Onyx 17.8
This means that Plesk does not have any management tool for Postgres databases shipped with it.

I suggest to include pgadmin in Plesk installation since the latest ve
rsion of this software (2018-09-06 - pgAdmin 4 v3.3 Released) has just been released, with adequate security. More info about it you can find here:
https://www.pgadmin.org/

It would really help, if plesk logs/audit every action, which can be done at the hosting Services: Customers, Domains, Subscriptions.

Each new or changed settings should be logged.

Thus would reduce our support.

I would like plesk to have support for React Apps created with "create-react-app". Thank you so much

Currently, Plesk Repair Kit extension does monitor in real time the CPU and RAM usage per domain: https://support.plesk.com/hc/en-us/articles/360007784053-Is-it-possible-to-monitor-CPU-Memory-like-in-Health-Monitor-per-domain-subscription-basis-

However, it doesn't register/save and historical usage. It would be really helpful that this extension would keep a CPU and RAM usage history, a graph, a timeline, in order to plan CPU and RAM limits set by CGroups Manager.

Currently, Plesk for Linux filters out IPv6 addresses that were assigned dynamically by use of Stateless Address Autoconfiguration, or other means: https://plesk.zendesk.com/hc/en-us/articles/115000239114

This greatly limits IPv6 functionality in Plesk due to the fact that all hyperscalers (Amazon, Google, Azure, Vultr, etc.) provide IPv6 addresses using the autoconfiguration method.

Argon2 is a new feature of PHP 7.2 as stated here: http://php.net/releases/7_2_0.php. It won the password hashing competition and is the recommended hashing algorithm.

It must be enabled my re-compiling PHP 7.2 with `--with-password-argon2`.

Allow the ability to assign separate SSL certificates for multiple mail servers.

MY Zonetransfer failed since months without noticing it.

As my *****-dns provider changed the IP address for the AXFR-Servers.

If Plesk would accept a FQDN, this wouldn't have happened.

When a subscription is suspended if some limits are exceeded, domain management becomes unavailable for Plesk users.

Plesk installer should check if 3rd-party firewall like APF is installed on the server and show a warning.
