    Security Updates

    I didn't install any kernel's myself. However I'm not running any containers...only VMs. Ah ok...I saw this chart and assumed Debian was running a higher version : https://en.wikipedia.org/wiki/Linux_kernel_version_history Can I just squeeze in that last question about apt autoclean...

    Security Updates

    Ok...so seems like that work flow does not upgrade the kernel? I am inside a VM that has run all commands and rebooted twice yet it is still running an old kernel. root@server:~# hostnamectl Virtualization: kvm Operating System: Debian GNU/Linux 12 (bookworm) Kernel: Linux...

    Security Updates

    I prefer to do things via cli. So no need to run apt upgrade..., just apt update and apt dist-upgrade, then reboot. That will take care of proxmox. For the VMs (all are running Debian bookworm)..is the same rules?

    Security Updates

    I haven't updated in a while but I have updated many times. I don't know when I've rebooted last...I know its happened but I never did it unless I had to. Ok, so it sounds like I need to setup a routine when I update, upgrade, dist-upgrade and reboot. I will also sign up for security...

    Security Updates

    Rebooting is not currently part of my process. I can make it happen but that requires downtime of course and critical things are running on this server. I have never run dist-upgrade...I didn't even know about it honestly. To answer your questions : root@server:~# apt update Hit:1...

    Security Updates

    I am currently setup running the no-subscription repo. And I do the normal apt update/upgrade. However this doesn't upgrade the kernel right? I'm not sure what is required for that. Also, 6.2.16 is not getting patched any longer so I'm not clear how that is going to help. Thanks for your...

    Postfix not working = where are the logs?

    You likely don't have rsyslog installed. apt install rsyslog I was able to find what I needed via ‘journalctl -u postfix’. That let me learn that I was having an issue with how credentials were handled

    Proxmox 8 Login : Fail2Ban not working

    I gave up and decided the best approach was to block access to the form via firewall.

    Hello everyone, I am trying to setup postfix to send me system emails via gmail exchange. I've had this setup without issue on proxmox 7. I am now running proxmox 8 fully updated. I set everything up. Unfortunateyl the following two commands (using proper email addresses) do not work. ```...

    I don't understand what Firewall:Yes does on virtual machine?

    They explain it all in this thread. The VM is separate and requires all rules applied to it. Just put the security group on the VM as well as the datacenter.

    I don't understand what Firewall:Yes does on virtual machine?

    I thought that applying a security group (the one called "datacenter" but I can rename it) to the VM that declared port 22 open would do that. For some reason it isn't working and I don't understand why. Could it because it is being used at the datacenter level already? Thanks for your patience.

    I don't understand what Firewall:Yes does on virtual machine?

    Sorry...my security group naming convention I think confused matters. I have a "datacenter" security group...it is currently applied to my datacenter and handles allowing port 22 for a specific IP only. This works perfectly for my hypervisors. I want the same rule to apply my VM. It seems...

    I don't understand what Firewall:Yes does on virtual machine?

    Hello everyone, I have 2 security groups. One is applied to the datacenter and allows port 22 access. Another is applied to the virtual machine and allows VPN access. This works fine as far as I can tell. However, today I found the setting, under a virtual machine => Firewall => Options =>...

    Proxmox 8 Login : Fail2Ban not working

    Hello everyone, I followed this guide : https://pve.proxmox.com/wiki/Fail2ban Then implemented all the attempts @ https://forum.proxmox.com/threads/pve-8-0-%E2%80%93-fail2ban-log-locations-missing.129338/ When I manually trigger the maxretrys nothing happens. When I run the test code provided...

    Simplest redundancy setup for two servers

    Thank you for the detailed response. Based on some reading it seems one option I have is purchase a cheaply hosted 3rd member for the cluster that does just voting. Does this seem like a good option in your opinion? In regards to IP management. I've set up PF sense before but that was all in the...

    Simplest redundancy setup for two servers

    Hello everyone, I'm a relatively new system admin. I have two dedicated servers at two different data centers. I was hoping to find a simple setup where my second/backup server was kept "hot" and I was able to swap to it if things went south on my primary server. Could someone tell me the...
