  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Question SELinux blocks outbound connections for FTPS from Backup Manager

J.Wick

Regular Pleskian
Server operating system version
Rocky LInux 8.6
Plesk version and microupdate number
18.0.46 Update #1
What I'm about to discuss took me literally a full day of troubleshooting.

Last week I migrated Plesk and clients from Centos 7.9 to Rocky Linux 8.6.

Trying to set up the FTPS (Non-PASV) settings in Plesk Backup would not connect fully. The curl command the Plesk error suggested worked at the command line. I have my FTPS on a random port 2121.

I figured out how to enable to log the firewall and saw all the connections getting dropped.

I disabled SELinux, and everything worked.

I'd like to utilize as much security as possible.

How can I learn of these SELinux conflicts and make exceptions with Plesk?

It would be nice to have Plesk report these errors instead of having to burn a full day figuring it out.
