• 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.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Fail2ban default blocking port

Paul Tog

New Pleskian
Hello all,
i'm running 12.0.18#34 on PCS dedicated server.
i recently discovered that some of the default jails on fail2ban that is shipped with Plesk 12 were not working correctly.
Let me explain what i mean.
For instance, the plesk-panel jail. The logs were parsed correctly, the command was successfully appended in iptables list, the fail2ban log was updated. Still, the intruder was not blocked. I kept reading "already banned" on the fail2ban.log but actually there was no blocking.

After some checks, i found out that fail2ban default configuration states SSH as default blocking port.
that means, the block was working but only for ssh hits. thus the plesk-panel admin page hits were passing through.

since i added port=http,https on jail.local > plesk-panel and did it a restart on fail2ban service, only then did it start to actually block incoming hits.

I think this should be verified by programmers group and maybe include a fix in some future minor update.

Hope this helps someone.

Regards,

Paul T
