    DNSBL - How does it work

    AIUI all specified DNSBLs are queried. There's no random/round-robin arrangement though queries might be run in parallel. Your understanding of the default multiplier is correct, each site will have weight 1. 20 DNBLs seems excessive!

    VLAN Bridge Interfaces - Makes Sense?

    My config would seem to differ from yours in that I did not define vlans directly in the web UI. I just entered the ethx.y under bridge ports when creating a bridge. They appear in /etc/network/interfaces as auto vmbr1 iface vmbr1 inet manual bridge-ports eth0.10 bridge-stp off...

    VLAN Bridge Interfaces - Makes Sense?

    For my setup, I assign single ports ethX.Y to traditional bridges rather than use vlan aware bridges or OVS. Like you, I prefer it as it seems more explicit, e.g. in the web UI. AIUI the argument used to go that vlan aware bridges were more convenient as you reduced the need for new bridges and...

    Where to edit SMTP reject/error codes?

    There is postfix's smtpd_reject_footer

    running out of space

    Logs (/var/log) or default local pve storage (/var/lib/vz) might also be the culprit. Check directories under /var du -shx /var/*

    [TUTORIAL] Proxmox + Security Onion without OVS

    Thanks for posting this. I've used your hookscript and seems a simple solution to mirroring traffic with traditional bridges. One typo, I think, in sub RemoveMirror promiscuous mode should be turned off: system("ip", "link", "set", "$target", "promisc", "off");

    Docker support in Proxmox

    I have not removed apparmor but I have noticed it is not started in PVE debian containers: Bullesye ~# journalctl -b | grep apparmor Aug 10 22:31:22 ct1 apparmor.systemd[62]: Not starting AppArmor in container Bookworm ~# journalctl -b | grep apparmor Aug 10 23:40:03 ct2 systemd[1]...

    Incomplete disk IO stats after upgrading to PVE8

    After an apt dist-upgrade and host reboot yesterday evening, my CT docker guests' disk graphs have sprung to life and are reporting IO again. The upgraded packages: libpve-common-perl:all 8.2.2 qemu-server:amd64 8.2.4 pve-docs:all 8.2.3 proxmox-kernel-6.8.12-1-pve-signed:amd64 6.8.12-1...

    Issues restoring PVE via Clonezilla

    Have you ever, in the past, managed to successfully restore a clonezilla disk image that contained lvm-thin volumes? I've shyed away from it due to seeing similar logs from clonezilla regarding volumes on LVM-thin VGs. Consequently I only use clonezilla to backup the PVE system disk, which in...

    [SOLVED] Missing /run/sshd in Bullseye standard zst template

    Bear in mind /run/ is on tmpfs, and /run/sshd created when sshd initiated on demand via systemd in debian lxc. I once had issues with sshd in the debian container.

    opnsense guest trim - reclaim host storage space?

    Just a follow up. I checked the pfsense guest. camcontrol output is similar to that of the opnsense guest. However, trim is enabled for rootfs. I must have manually enabled it on the pfsense guest post-install too, but before applying a major upgrade. My memory fails me on that one. Next time...

    opnsense guest trim - reclaim host storage space?

    Thanks. Next time I will try the guest 'ssd emulation' option and see if the opn installer recognises it as such. The camcontrol output in post #1 is apparently why trim was not enabled. But I'd have expected it to display something more informative - the above appears to be a failure of some...

    opnsense guest trim - reclaim host storage space?

    OK, it does seem that trim is working in as far as: I create a large file in the guest, I see the lvm-thin volume on the host grow and then shrink back when I delete the file in the guest. However, I don't seem to be able to reclaim the jump in storage needs following the opnsense guest upgrade...

    opnsense guest trim - reclaim host storage space?

    Storage is lvm-thin. The opnsense guest config is similar in most respects to the pfsense guest I mentioned in my reply to @sw-omit. # qm config 101 affinity: 0,4 agent: 1 balloon: 0 boot: order=scsi0 cores: 2 cpu: host hotplug: 0 memory: 2048 name: opn net0...

    opnsense guest trim - reclaim host storage space?

    I was considering something similar but would like to get to the bottom of it because I don't see these issues with a pfsense vm with identical config. That vm has been through several upgrades and the disk use (lvm-thin backed disk and PVE backups) has remained the same size (1.2GB) for several...

    opnsense guest trim - reclaim host storage space?

    I created an opnsense 24.1 guest. Backed up, this vm uses 1.2GB. I upgraded the guest to opnsense 24.7. The backup now occupies 2.84GB. I'd enabled the discard option on the vm. But it seems the opnsense installer, unable to determione the disk type, did not enable trim: ~ # camcontrol identify...

    Message size exceeded and Tracking Center

    IME messages that exceed the postfix maximum message size are rejected and logged but the events do not appear in the Tracking Center. I think it would be helpful if they did.

    GRUB BIOS boot packages

    Those grub-pc and grub-efi-amd64 preinst, postinst, prerm, postrm scripts look pretty complex. I will put any OCD tidying up to one side on this occassion!

    GRUB BIOS boot packages

    That could be it! Thanks for the help. I mean to look at the grub packages' pre/post install/remove scripts to see what they do in respect of running grub-install and update-grub. I'm old enough to remember LILO and once had a stab at installing linux (unsuccessfully) on an hp ux machine...
