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

The possibility to setup a replication for MySQL

By default the HTTP header 'x-powered-by: PleskLin' is added to HTTP responses.
And with PHP, even the version number is included: 'x-powered-by: PHP/7.3.5'

For security it is better to not give such information, as it may expose you are using outdated software with known vulnerabilities.
Currently it is possible to remove these headers, but it requires some manual actions using SSH (https://support.plesk.com/hc/en-us/articles/115000385274)

My suggestion is to create page to be able to manage such header additions for all websites and services.

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

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!

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/

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.

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

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.

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:

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.

Ability to manage all Firewall rules via Plesk GUI on Plesk for Windows

I would like to have the possilibity to define an expiration time for customer/users created via Plesk.

eg.

Customer1 / user example / password expire after 30 days.

10 days before an email notification is sent via email or an warning message via Plesk > customer account is displayed.

Want to have a quota per user as it possible on Plesk for Windows.
Not a limit over hard-disk quota via subscription.

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 have a really powerful hardware, however I still see how low values are by default on a 30+ domains license and such a server hardware: Plesk doesn't adapt to license or resources at all.

Ultimately, I do not like try increasing the value progressively and restart apache or any other service a few times on production server, then see when the issue comes back because I didn't increase it enough approach.
It would be better if there was an automatic increase of the values, if applicable, depending on your license and/or system resources.

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