    IO delay

    I upgraded my hosts and removed all SWAP's from the LXC clients and this is the result. Now I wonder if the problem was the code or the SWAP. I'm betting LXC don't like ZFS with SWAP.

    Syncing IP's from fail2ban

    Actually I'm using Proxmox FireWall's rather than "Enterprise Firewall" for many reasons. Most importantant is the cluster and the flexibility it provides. It's really simple and scalable. It's client friendly (LXC's are managed by clients themselves.) No need to write a ticket and wait a few...

    "Cloning" - nested Proxmox

    I was trying to clone new Standalone Proxmox installation on KVM by doing a backup to PBS server then restoring that backup as a new virtual machine. Worked quite well. Then I updated /etc/hostname /etc/hosts /etc/network/interfaces and regenerated ssh keys with ssh-keygen -A After reboot I...

    Unexpected tunnelin/forwarding attempts after upgrade

    I'm thinking this maybe the cause: root@vm2404:~# cat /var/log/syslog |grep block Oct 29 14:42:33 vm2404.ic4.eu kernel: [681424.800987] vmbr1: port 9(fwpr700p0) entered blocking state Oct 29 14:42:33 vm2404.ic4.eu kernel: [681424.808510] fwbr700i0: port 1(fwln700i0) entered blocking state...

    Unexpected tunnelin/forwarding attempts after upgrade

    After upgrade this message started occasionally flash on LXC terminals. channel 3: open failed: administratively prohibited: open failed Then after a few seconds it disappears and says something about forwarding but too quickly to see. Remote port forwarding failed to listen on port XXX Oddly...

    rsyslog

    I can't seem to get remote logging to work on Debian12 LXC containers. FQDN works on Qemu servers but the same rsyslog.conf file does not give full name from LXC container. Any idea what's going on here..?

    Manual installation on Debian 12

    If Debian 12 has been installed with minimal network boot CD/ISO/USB then it probably does not include bridge-utils which is mandatory component to get vmbr bridges to work. Make sure you install it with apt install bridge-utils first then fix these files /etc/hosts and /etc/network/interfaces...

    [TUTORIAL] Advancing Proxmox Mail Gateway (especially Spam and Virus Detection)

    [%- IF pmg.mail.rejectunknownsender %] reject_unknown_sender_domain[% END %] IMHO - That should be default option.

    root@pam user and key based authentication

    hmm. I don't understand why root@pam always asks password when I do this: /usr/bin/proxmox-backup-client backup etc.pxar:/etc var.pxar:/var --repository backup.ic4.eu:store1 The backup-client is Proxmox host and should have proper keys to backup server.

    Remote Syslog

    I have always felt journalctl was a step in wrong direction. "KISS. Keep It Simple Stupid." Those are words to live by. Other as good is... "If it's not broken don't try to fix it."

    Just installed Mail Gateway 8.0.7. Remote logging works but FQDN stopped working. $PreserveFQDN on

    virtual_alias_maps

    I have been testing PMG for a while now and I have to say I'm impressed. I like how simple it is to use. There is one thing that it's missing though. You can have finer grained control (than domain level) by putting me@example.com in transport_maps by using virtual_alias_maps. # transport...
