That is very disturbing news, @cgimicro. I have exactly the same content in my /etc/fail2ban/jail.d/defaults-debian.conf. What version of fail2ban were you using? I am using Debian Bullseye with Proxmox 7. Were you using the same or Debian Buster with Proxmox 6? I have not been able to find...

Nevermind, I explored the bug tracker and added an bug of type enhancement: https://bugzilla.proxmox.com/show_bug.cgi?id=3719

Hello everyone! I have been investigating how to change the MTU from the default value of 1500 to 1400 in my newly installed LXC container (TurnKey PostgreSQL) on my Proxmox 7 cluster and, after some investigation, the only way I have found to make it work is to edit the file...

Just found out and read the IP Aliases, IP Sets and Default firewall rules sections on the Proxmox VE Administration guide but on my installation (Debian Bullseye 11 with added repository, not Proxmox ISO) neither those aliases nor default rules are there. But if I execute sudo iptables --list...

Hello everyone! I have a recently created Proxmox 7 cluster made of a number of hosts. These hosts have a public IP address each and also a private IP address (192.168.1.0/24), connected via VLAN with id 4003, which is used by the hosts to talk to each other (it's the IP address I used when...

Precisely the reason of my question. It would seem like https, in this context, is just an alias for port 443, but it could also mean what @hata_ph said: https (protocol) over port 8006.

Hello everyone! I have finished setting up two dedicated servers with Proxmox 7 (Debian Bullseye 11) on Hetzner. Both hosts, once in a cluster, are expected to have two type of VMs: 1. Those with a private IP address and an additional public IP address (e.g. web server). 2. Those with just a...

Do you know why the port directive in the jail.local file includes https and http as well as 8006, which is the default port? I noticed it's the way the Proxmox wiki recommends it, but the reason is not stated there either. port = https,http,8006 Also, the file...
