verzeiht, dass ich diesen Thread nochmal nach oben hole. Da wir in den kommenden Monaten unter Umständen die Hardware unseres PVE/Ceph-Clusters erneuern werden, interessiert mich das Thema grundsätzlich. @Stefan_Malte_Schumacher, magst Du schreiben, wie die Geschichte weiterging? Und so ins...

to be clear: The OPNsense VM is crashing your PVE host? uh. I would try some other VM guest OS, a Debian for example. And also some LXC testing, to find out what *doesn't* crash your host. What kind of storage setup do you use? Maybe you could post your OPNsense VM configuration?

we just upgraded our non critical PVE playground to pvetest with kernel 6.5 and ZFS 2.2 - no issues so far. It's a single node PVE with two oldie but goldie Intel Xeon E5-2697 v2 and 512 GB RAM. / is on a single SSD (LVM), and there is a ZFS based storage. zpool status <poolname> shows Some...

Hey there, our vulnerability scanner recommends us to disable TCP timestamps. Is it safe to do so on PVE/Ceph, PBS and PMG? Thanks and greets Stephan

For the record: We didn't notice any unwanted side effects due to this configuration change. So I mark this thread as solved.

Thanks a lot for the explanations! me too. The sender told us that the mail was generated by their SAP - and therefore it's correct by definition. :rolleyes::D MS Outlook 2019 and Mozilla Thunderbird 115 show a blank body and the attachment - as normal user would "expect".

How can I send you an example? I tried starting a "conversation" with you, but it seems I'm not allowed to do so. :D

Hi there, we received a solicited mail that doesn't contain a body tag. And there is a file attached. PMG classified the mail as spam (which is not a problem for us). PMG's WebGUI (Administration -> Spam Quarantine) says "unable to parse mail", and at the bottom of the window there is "No...

Thanks for your reply! I just did the change, everything looks good so far. I will observe this the next few days and report back. One question for understanding: As expected the additional line occurs in /etc/postfix/main.cf. But it doesn't occur in the output of pmgconfig dump. Is this...

Hi there, our vulnerability scanner recommends us disabling answering VRFY and EXPN requests by configuring disable_vrfy_command=yes Is it safe to do this in a PMG installation? Thanks and greets Stephan

ah, so you mean, there is no http://download.proxmox.com/debian/pbs-client bookworm InRelease? I didn't try it yet.

Hi there, we just upgraded our PBS to version 3. And we run a couple of Debian bullseye systems with Proxmox Backup Client. Is it safe to change the Proxmox repo to bookworm on a bullseye system, or should we wait until we upgrade the entire system? Thanks and greets Stephan

I don't know for sure, but yes, I assume that there is a lot of "small block size" reading before data is transfered,

Hey, thanks for your reply, and sorry for my late reaction! I tried this, but unfortunately the second machine has just a bunch of HDDs, and so it's too slow for PBS (syncing at about 50 MB/s). With rsync I get about 300 MB/s, so I would like to stick at this path. So again: What's the clean...

I just upgraded a non productive single node (ZFS based storage, connection to a PBS) to PVE 8.0beta - everything looks great! :) ...it's so hard to break a PVE... :D

wow, wieder was dazugelernt, vielen Dank! Tatsächlich stehen auch bei uns im syslog nicht die Temperaturen, sondern der "Gesundheitszustand", meist Werte zwischen 70 und 80.

Stimmt, Du hast recht (ich hatte die Lagertemperaturen im Kopf). Und da das die letzten syslog-Einträge sind, bevor die Kiste abschmiert, könnte der Hund tatsächlich dort begraben sein. In den syslog-Einträgen steht durchaus "Temperature_Celsius". Ich habe gerade ein paar Stichproben bei uns...

alles klar, dann wird an dieser Ecke wohl alles passen. EIn paar Stunden memtest hast Du sicherlich schon gemacht, oder? Und wie gesagt würde ich dann mal den einzelnen Disks auf den Zahn fühlen. 76-77 Grad Celsius sind für SSDs und NVMEs nicht so tragisch, oder?

Die verändern sich bei uns gefühlt ständig. :p Ich gebe Dir recht: Solange sich das Umfeld nicht entscheidend ändert, besteht kein Grund zur Eile. Nichtsdestotrotz wird der Tag kommen, an dem 7.x EoL ist. Darüber hinaus bringt jedes Software-Update potentiell Verbesserungen. Neue Features, mehr...

Mit 24/7 und Mini-PCs habe ich zwar keine Erfahrung, würde aber sagen, dass es auf jeden Fall einen Versuch wert ist. Ich schätze, dass der CPU-Lüfter hier die Achillesferse ist, da die Dinger klein sein und deshalb schnell drehen müssen (und ich unterstelle, dass die Mini-PC-Hersteller hier...
