I always install zram-tools Have you played with systemd-zram-generator? Pretty much fire and forget; by default it can use 25% of RAM or 4GB whichever is smaller but as with everything Linux this can be adjusted. Not (yet?). I find zram-tools pretty much "fire and forget" so I haven't se...

I always install zram-tools (https://wiki.debian.org/ZRam), it's good for small computers (I had that with my Nokia N900 with 256MB of RAM) and for "large" servers (e.g. 64GB).

Swap is always necessary (aka not recommended to disable).

Thanks to all for the replies reinob : If you look here: https://www.debian.org/distrib/ you will see that Debian does offer an ISO intended to be used for a server (headless) installation. I am not sure I am not following you. Thus in what link of the mentioned page is possible get a iso for serve...

This made my day :)

Usually it is advisable to use the official website and documentation, rather than go on a Youtube tutorial hunt (IMHO anyway).

I think OP wants systemd to reboot without waiting for a service to (gracefully) stop. Obviously, the "or kill my process" makes no sense, because the kernel will not reboot until all processes have vanished. They could change the TimeoutSec in the [Service] section of the unit to somethin...

Hello @reinob, Note that also the browser (OP didn't say which) may have its own settings of DNS resolving, so even if the system resolver (using /etc/resolv.conf *and* /etc/nsswitch.conf) is pointing to whatever VPN DNS server the OP is expecting, the browser may be doing whatever it likes. Are yo...

@donald, I reported two things, but have been merged and intermixed. The first thing was: the forums.debian.net *can and does* send e-mail over IPv6, and yet its SPF record does not list the IPv6 address(es) that it can use. They should be added to the SPF record. Otherwise, depending on configurati...

re. SPF: I received forum notifications at my server over IPv6. The SPF record should contain every address the MTA can use to send e-mails. (and yes, I was aware of the fact that the forum mail wasn't up to standards until recently — triggered by gmail enforcing SPF/DKIM for larger senders, but as ...

Hello, The DMARC record for forums.debian.net points to _dmarc.forums.portalias.net, which states: _dmarc.forums.portalias.net. 600 IN TXT "v=DMARC1; p=quarantine; sp=quarantine; pct=100; rua=mailto:root@forums.debian.net; ruf=mailto:root@forums.debian.net; ri=86400; aspf=r; adkim=r; fo=1;"...

Hello, I have noticed that the SPF record for forums.debian.net states: forums.debian.net. 3307 IN TXT "v=spf1 ip4:159.69.48.177 ~all" but e-mail can actually be delivered over IPv6 (2a01:4f8:1c17:7bb3::1), which results in SPF considering the address "neither permitted nor denied&quo...

It could be any number of things, but since you didn't care to even mention how you connect (openvpn? wireguard?), how your networking is configured (systemd-networkd, ifup/ifdown, some GUI network manager?) or the contents of your /etc/resolv.conf, and whether you have any "helpers" chang...

Without knowing what Zabbix does or does not in order to send (submit) e-mails, I note that GMail is not the best option for this, as it generally doesn't allow standard password authentication. (Plus using "http://smtp.gmail.com" is definitely wrong).

Thanks, @bin for reporting this!
Lately I visit the forum not as often as in the past, but I was getting the impression that I'm going nuts :)
The forum also asks me more often to log in, maybe the cookies expire sooner than before.

In any case, I'll watch this thread.

The short version is that the only way to get resolvectl is to install systemd-resolved, which is not installed by default in Debian. hi, without resolvectl then do you have any kind of dns cache (after a default bookworm install)? if you don't use a caching resolver (resolved, dnsmasq, unbound, et...

FWIW "history -c" and "history -w" are bash builtins, which will work in any OS, including Ubuntu (as stated by the OP) and, obviously, debian.

@filse392: did you try this at all, before asking?

It looks like you open "filename" to read ("rb+", note that "b" is ignored, so "r+" would suffice), and then immediately you open *the same file* to write ("wb+"). When you open a file for writing, the file is *truncated*, so when you then read data ...

Normally if one wants to install a mail server, like postfix, the first things one does is to read the excellent documentation that it brings. I mean, you wouldn't just build a nuclear power station "OUT OF CURIOSITY AND TINKERING" and expect a random Internet forum (which is about debian,...
