Hi,
I noticed that if I set the OUTPUT policy to DROP, I need to add a few rules by default for SSH, migrations to work if I add another ringX address. Could it be that some rules that gets set by default for INPUT may have been forgotten in output ?
I see the usual ports...

Hi,
I've purchased a HUNSN mini PC like this one (amazon link) and installed Proxmox VE 7 on it and it seems to run fine so far. After trying to find a way of passing-through a M.2 Wifi/BT card (like this one, amazon link) to a debian VM, and not finding one, I reached out to the seller which...
Hey all!
Perhaps a bit of a beginner question here, especially on the security side. I got a notice for 2 vulnerabilities with open ssh version that is running on ProxMox. It is mentioning that OpenSSH_8.4p1 is vulnerable on CVE-2023-28531 and CVE-2008-3844.

Hi,
After checking quite a few articles found here and on some other websites, it's still not clear for me how one can add custom IPTables rules for each VM.
Checking the current host with just one VM at the moment I can see:
-A tap100i0-IN -p udp -m udp --sport 67 --dport 68 -j ACCEPT
-A...

Abend zusammen,
Wie „sicher“ ist eigentlich PCI-Passthrough?
Ich bin aktuell am überlegen folgende Konstellation zu bauen:
1 Host mit einer zusätzlichen Netzwerkkarte. Die Karte hat 2x 10G.
Die beiden Ports sollen per PCI-Passthrough an eine Virtuelle OPNsense weiter gereicht werden.

Hi,
i got 2 questions to properly secure my data. The setup is one server running PVE an another server running PBS. All on premise. The VMs are stored on thin-provisioned LVMs that are encrypted using LUKS. The key is stored on a hardware token. I am really happy with that. Works great and...

They simply set /proc/sys/kernel/core_pattern to execute user provided binary in host context by triggering coredump inside of privileged docker container.
Can this be done with privileged CTs on proxmox? Or is...
