#301 Re: Installation » [SOLVED] mail filtering in console » 2023-03-31 06:40:09

The traditional unixy solution (and likely the lightest on resources) is probably the old (fetchmail / getmail) -> procmail (+formail) -> (maildir / mda) construct. Assemble parts as needed smile

I was running fetchmail + procmail via cron as my mail filtering / delivery system for many years, though I have since moved to getmail for retrieval and  sieve within dovecot for filtering, as the box also acts as an IMAP server these days anyway.

The 'net at large should provide plenty of fetchmail/procmail/formail info, it's a system as old as the hills. Procmail filter syntax is a mite arcane, but it's very powerful once you get your head around it. Also here.

Alternatively (or if you're discouraged by the length of procmail's beard), you might just want to set up a real mailserver and use sieve scripts. As mentioned I use dovecot, but there are several other options.

As for alpine... I'm not sure why one would want to use a mail reader for automated retrieval and filtering, but if it can do it it can do it I guess. I'd consider fetchmail / getmail and a filter and/or mda of choice the more appropriate hammer though.

Any more detailed suggestions dependent on more detailed explanation of your setup (e.g. "mail dirs" meant in the traditional *nix maildir sense or folders within a maildir / mbox, where these boxes are and how your end-user readers access them, where your IMAP server is, etc.).

All the above assumes primarily syncing to and working with mail in local mailboxes or on your own mailserver (since that's how I do it), If you're more into manipulating a remote IMAP server you don't control I'll be of little use to you, and maybe something like alpine is the way to do it...
Or perhaps imapfilter. That one looks pretty promising for such a task, and could be combined with e.g. getmail or imapsync if you want a local backup as well.

I have, and it has been. My question, i.e. are bugs in backports handled separately as they are in debian, appears to be answered by stint of said bug report being accepted.
It would still be nice if this was clearly explained on the bug reporting section of the devuan site.

That it was fixed so quickly is great. Logging being screwed up on multiple machines for multiple months before I noticed this, and me (who is not a package maintainer) being the only one who did... That isn't great at all.

Which is a real pity as Devuan could use another 'somebody', more so if it is one with your bug-tracking skills.

You can take my word as: I am getting ever closer to migrating systems that I need to work reliably, without the intrusion of random "oops" class bugs in critical packages, over to Slackware or FreeBSD.

Apparently, Devuan derives from Debian and Veteran Unix Administrators... I took this to mean that the distro would cater to administrators (who, ya know, administer things, like production servers), and inherit the stability and reliabilty of Debian... Rather than turn into another hobby distro for anti-conformist tinkerers with old laptops.
I appear to be mistaken, if the apparent focus on desktop customisation and the attitude I see from many people here have any bearing on things.

As for my bug-tracking skills... That's kinda my point. If my relatively meagre expertise and attention are all that stands between Devuan and undetected broken packages in the repos, we have problems. How am I the only one to have noticed this, in rsyslog of all things?

Altoid wrote:

If you need the type of trust and assurances that Debian has given/gives you, you may want to consider going back to Debian.

I need some level of confidence that I can run headless servers, with unattended upgrades, and not have them break unexpectedly because somebody forgot to change the distro name in a default config or misplaced a patch in a shipping package version.
I especially need them not to stay broken through multiple updates - as happened here until I pointed out the borked script.

Hell, I don't have something as important as system logging go tits-up with a routine upgrade even on my bleeding-edge Gentoo desktop. If Devuan can't match the rollingist of roll-your-own rolling-release distros in terms of core package QA, I really don't know what purpose it serves.

What are we trying to achieve here anyway, Debian without the init upheaval or Debian without the stability and reliability?
Maybe FreeBSD is the answer after all.

Debian asks that bugs in backports be reported to the debian-backports mailing list, however there appears to be no corresponding information on the Devuan bugtracker page... Do bugs in e.g. chimaera-backports go to the main bugs.devuan.org address or what? Who exactly maintains these packages anyway?

Owing to the above lack of information, I'll post this here for web-search purposes: rsyslog from chimera-backports is currently broken WRT logrotate, due to (the usual) unpatched systemd bullshit. Do I assume this package is pulled direct from debian?

Specifically, the file '/usr/lib/rsyslog/rsyslog-rotate' installed by rsyslog-8.2302.0-1~bpo11+1devuan1 (and 8.2208.0-1~bpo11+1devuan1 before it) contains:

#!/bin/sh

if [ -d /run/systemd/system ]; then
    systemctl kill -s HUP rsyslog.service
fi

Where it should be (and is in rsyslog-8.2102.0-2+devuan3):

#!/bin/sh

if [ -d /run/systemd/system ]; then
    systemctl kill -s HUP rsyslog.service
else
    invoke-rc.d rsyslog rotate > /dev/null
fi

Thus, logrotate fails to HUP rsyslogd if rsyslog is installed from backports, thoroughly borking log rotation (and things that read those logs).

Please, please tell me somebody is actually checking packages (and their config files) for systemd-isms before allowing them into Devuan (-backports), this is not the first time this kind of thing has happened and it is seriously eroding my trust in the distribution.
Syslog is a critical service, breaking it during routine updates is an extremely bad look. Installing backports on debian, by contrast, has caused me no grief at all in the last ~20 years.

# apt purge pulseaudio && apt autoclean && apt autoremove

Much as I too dislike pulseaudio, if one wants such niceties as on-the-fly switching of bluetooth sinks and whatnot, pure ALSA is a PITA.
While it is still far too complicated IMO, pipewire does at least solve some of the more glaring deficiencies of pulseaudio. Anyone wanting modern convenience features on a laptop or such will probably need one or the other.

User479 wrote:

Edit 1: Except the phone and tablet have systemd, of course, and setting up pipewire without that is a bit more complicated.

Edit 2: Actually, the "Alpine solution" turned out to be pretty simple.  pipewire-launcher.sh worked without modifications.

FWIW, I have been playing with pipewire on my (openrc) Gentoo desktop too. Gentoo uses exactly the same pipewire-launcher.sh (anybody's guess who nicked it from who), and while it should work on any distro it does come with one problem - it has no facility for terminating pipewire / wireplumber when the user logs out.
That's not a big deal on a single-user system, nor is it a problem if one has logind set to kill user processes (which in turn breaks the old-school ability to background a task and leave it running after logout though).
If neither of those are true however, it results in stale pipewire processes left running and blocking the sound device when one user logs out and another logs in.

To solve this, I lifted a solution from slackware, namely using daemon to manage the equivalent of systemd "user-units".

The result is 3 autostart files (pipewire, pipewire-pulse, wireplumber), like e.g.:

[Desktop Entry]
Version=1.0
Name=Pipewire
Comment=PipeWire media server
Exec=/usr/bin/daemon --bind --respawn --pidfiles=$XDG_RUNTIME_DIR --name=pipewire /usr/bin/pipewire
Terminal=false
Type=Application
X-GNOME-Autostart-Phase=Initialization
X-KDE-autostart-phase=1
X-GNOME-HiddenUnderSystemd=true
X-KDE-HiddenUnderSystemd=true
X-systemd-skip=true

Zero launcher shell scripts or hacky anti-race sleeps, and the ability to do things like:

$ daemon --list
cdemu
pipewire
pipewire-pulse
pipewire-wireplumber
systembus-notify

As well as stopping, starting, and restarting these user daemons without resorting to pkill and co, giving them pid files, retrying failed starts, and binding to the user's logind session so they exit when they should.

Fractionally more effort (IIRC daemon is in the devuan repos already), but cleaner and more flexible IMO.
Just something to consider, FWIW I strongly suspect we're going to need something like daemon for more than just pipewire in future (I'm also using it for cdemu-daemon and the dbus-notifier part of earlyoom here), as systemd user-units become more popular.

To return to the OT, yes, this /.config and /.cache garbage is created on chimera (default desktop-live/refracta install) as well, and AFAICT the culprit is pulseaudio. Removing pulse will prevent their creation but not remove them if they exist, as they are not tracked by dpkg (for extra nastiness).

Whatever ones opinion of pulseaudio, it shouldn't be creating XDG configuration directories in the system root and so long as devuan is shipping it in the default desktop, I absolutely consider this a bug to be fixed.
I don't have a debian install to compare right now, but my suspicion is that this has to do with pulse assuming systemd and doing broken things when started as root by traditional init (i.e. when XDG_FOO isn't set).

If you read the OP, you'll notice that there are no home directories involved at all, so XDG_HOME_WHATEVER has nothing to do with anything.
The directories in question are /.config and /.cache - i.e. hidden directories in the system root.

I don't have the machine with me ATM (I'll check later), but IIRC I've seen the same with a chimaera install, and only where pulseaudio is involved.
Whether this is a bug or just expected janky behaviour for potteringware, it is, at the least, extremely ugly.

how can i debug if the hardware is erroneous?

I'd start by passing 'debug' on the kernel command line and seeing if it spits out anything more useful, then proceed to booting a different operating system to eliminate software entirely.
Most anything will likely do for that, but since the hardware was almost certainly designed to run Windows, as distasteful as it may be that's not a completely terrible option for testing.

As for isolating a hardware fault, the obvious answer would be to try to reproduce the problem in as minimal a configuration as you can. Remove expansion cards and extraneous peripherals, swap or replace PSU, memory modules, that kind of thing.
I don't see a smoking gun in your logs (though I do wonder what exactly pppd is up to at the end there), so a process of elimination would be the next logical step.

Aside, what Altoid said. I have plenty of old hardware, some of it going back to the mid '90s, and it still works just fine.
Assuming something is no good simply because it's old is kinda silly (as is insisting on DOS filename extensions when we have perfectly good magic for that matter).

I probably wouldn't bother with it on a desktop pc, but for headless boxes, especially if you have many headless boxes you can't be arsed updating manually one at a time (or remembering they exist for that matter), it's pretty dang handy.

Fundamentally broken if you run systemd perhaps. On sane distros (such as gentoo), /usr on it's own partition is just one of a great many possible configurations, in this case filed under "may require an initrd, won't work with systemd, not recommended for newcomers".
split-usr is just another USE flag, and it's up to the end-user to determine whether or not it's set. As it should be.
The same goes, of course, for systemd itself.

As of this moment, a couple of applications I use still have file-collisions (in this case upstream binary names) with a symlinked /bin/, so I'll flip that flag when (and if) I'm good and ready.

modules-enabled should (IIRC, I actually run apache, but the config directory layout is much the same, it's a Debian thing) contains symlinks to files in modules-available, which in turn contain load_module directives pointing at dynamic module .so files.

Only you can explain the presence of that include line, it's certainly not in any default configuration shipped with Devuan.

Because following some random blog post and using third-party executable installers rather than the repos is a sure-fire way to mess up your install?
The debian documentation and discussion boards are replete with warnings not to do this, and for good reason.

Other than that, if you want help you will need to provide a whole lot more information (with command output and such in code tags, not blurry screenshots) than just "why not working". Nobody here is psychic, and I for one am all out of patience for guessing games.

I've never seen the traditional debian installer do anything funky either, but IME it's pretty trivial to screw up refracta, since it's really just a bunch of shell scripts, rsync, and yad/zenity.
There's no option go back if you miss something, precious little in the way of confirmation, and skipping or closing any of the random dialogs and terminal windows it spawns is likely to have it just truck on and copy the system regardless. i can totally imagine how one might end up in this kind of mess.
Perhaps I'm being unduly harsh here, but considering I was able to accidentally break the install process on my very first go (though not as badly as this example) it sure doesn't inspire much faith.

If the OP had provided proper reproduction steps, I might even be able to prove it too... oh well.

Random thought, I don't suppose we did anything... unexpected in the live session before running the installer, like, say mounting the existing /home filesystem somewhere?
It's just a thought mind, while I am looking at what I think is the current refracta scripts with one eye, I'm far too lazy to properly dig through that bunch of bash right now.

And another random thought, because I know HoaS just loves shellcheck...

Surely that would only make sense if I wanted to upgrade immediately 'testing' became 'stable'?

No, that's what "archive" (a=foo) matching is for.

a=stable will track whatever release is currently marked as stable (so it's liable to silently start pulling in packages from a new stable release as soon as it becomes available).
n=<codename> will track <codename> forever until you change it manually, regardless of unstable/testing/stable status.
n=${distro_codename} does the same, except that it uses lsb_release to determine which release codename you are currently running. When (and only when) you switch to a different release (i.e. change your sources and do a manual dist-upgrade), lsb_release picks it up, nobody needs to look at that file.

That last one has been the "safe" default in Debian for a long time now, and AFAICT the only reason it isn't on Devuan is that lsb_release was broken for a while (returning Debian release names).
IIRC lsb_release in turn was broken to work around yet another "we're 99% Debian but trying to pretend we're not" class bug. Of course. roll

All that is now fixed, so I see no reason not to put this trivial bit of automation back. smile

That's kinda my point WRT using ${distro_codename} instead of a hardcoded release. That's how Debian does it, and it allows unattended-upgrades to track the new release after a dist-upgrade with no manual changes to its configuration at all.

Ditto for the devuan-security line, I see no reason not to use ${distro_codename} there either, unless to create more packaging work.

Works fine on beowulf as far as a cursory test in a VM. Not so much on chimaera if one is using codename matching though...

I see the config template for Debian (50unattended-upgrades.Debian) references release as ${distro_codename}, and AFAICT from the python script, that's pulled from the output of lsb_release.
The config for Devuan does not (though it retains the reference to /etc/debian_version, which is nonsensical on Devuan), instead including hardcoded lines for beowulf.
The relevant (main, security) lines are also commented in the Devuan config, whereas for Debian they are not. Minor detail and all.

IMO since lsb_release returns correct information on Devuan, it would make sense to use ${distro_codename} by default here as well. Also changing /etc/debian_version to /etc/devuan_version for less confusion, since the former doesn't actually contain a release codename.

TBH I'm a little confused that the Devuan config deviates so far from the Debian version to begin with - all that's really needed is s/Debian/Devuan/g and some minor cleanup of the comments.

That "isw_raid_member" signature makes me suspect you are using BIOS "RAID", aka. Intel "Rapid Storage", in which case...

that the missing line in /etc/fstab "/dev/md0  /mnt/raid1  ext4  defaults  0  0" is the cause?

mdadm, (unless it has grown Intel RST support recently) has nothing to do with anything here. I also see no mention of any mdadm RAID arrays in that output.

If you really do have a software raid, mdadm (e.g. mdadm --examine --scan) should be able to find it, otherwise...

IIRC, Intel RST is handled by dm-mapper like any other BIOS fakeraid (ask google, I don't use it), and I expect your raid volume should be somewhere under /dev/mapper/... Not /dev/sdb2, which is where your root filesystem currently is.

What mounting an underlying member of a BIOS raid volume would do I don't know (will the BIOS resync on reboot? trusting which drive?), but the symptoms that you are reporting wouldn't surprise me at all.
This is all speculation mind, I don't use BIOS raid myself, and frankly I suggest you ditch it as well (unless you need to access the array from bare-metal windows for some deranged reason). Software (mdadm) RAID is better in every way.
