Simple way to scann all incoming and outgoing e-mails for viruses

[john doe]

Debians,

My MUA is connecting to mail.com for imap and smtp.
I have a Debian gateway server that I would like to use to scann e-mails
sent and reseaved.

Is there a way to scann incoming and outcoming e-mails on those ports
for viruses?

What I'm trying to avoid is to change the connection settings in my MUAs.

I'm not sure how realistic this is so I might refine my question based
on the provided answers.

It looks like the last time it was online with content was approximately
29 Feb 2020:

https://web.archive.org/web/20200229050405/http://www.aboutdebian.com/

I see that as of that date, the site had not been updated for Buster
which by that time had been released nearly half a year earlier.

After that the Web archive shows a blank page and captures from last
month show nothing Debian related.

Re: Late encryption of /home Partition

[Klaus Singvogel]

Hi,

thanks for all your help. It's working now as expected.

Fun fact: Had a small issue with the UUIDs, where I added a quote on left
side to a system config file, but none was allowed there. Therefore
(auto-)mounting failed (/dev/disk/by-uuid/\x22...) and it took some time
till the system came up without mounted /home.

For the sake of completeness: data loss was never possible, as it was a
fresh installed machine, which was never used productively.

Thanks again.

Best regards,
Klaus.

I've seen that bug before.  That's a change which got reverted, or at
least, the default behavior was returned to the previous norm.

Debian's /etc/systemd/logind.conf has

#KillUserProcesses=no

which indicates that the default is for this "kill everything the user
left running" setting to be disabled, as it was before the controversial
change.

I think this is a dead end for this particular question, because it's
an all-or-nothing setting.  Either *all* background processes that the
user creates get nuked when the user logs out, or *none* of them do.  There
doesn't appear to be a way to "mark" particular processes for reaping
while leaving the rest alone.

Maybe some other part of systemd offers more flexibility, but if so, I
don't know what part it would be.  I'm still waiting to see an actual
user-friendly *document* that describes how to use systemd.

systemd certainly does offer something here. It's related to what
processes are considered to belong to a "session", it came in with
version 230, and there was quite a stink about it from people who
wanted this not to happen, at the time:

/etc/X11/Xreset.d is a directory which holds scripts to be executed
upon termination of a display manager.  It may work to put a kill
script in there.  The /etc/X11/Xreset.d/README file has more details.
I use it to terminate non-X tasks which are started by my window manager.

I think of .xsessionrc a little differently.  It's the "novice mode" file,
which you can use regardless of which x-session-manager or x-window-manager
ultimately gets used, and without needing to take control of your whole
session yourself.

That makes it great for quickie "I just want to start xclock too" type
things, where maintaining a whole .xsession file would be overkill.

In the OP's case, though, they want something that "novice mode" can't
handle, so there's a decent reason to move to "advanced mode".

(I still wonder whether systemd offers anything relevant here.  And if
not, what the hell *is* the point of systemctl --user?  I've never used
it, nor found any reason to use it.  Yet.)

I think this is because you're starting it in the wrong file.
Everything in .xsessionrc should complete immediately. Use it
to set parameters and things like that.

> What can I do to terminate the process with x-session?

Start all your X clients and programs in .xsession. They should all be
backgrounded with &, as shown in   man xinit. There's an example at
about line 78 (buster version) on that page.

You'll see there that they start the Window Manager last. This has
disadvantages, in that you can't tell programs like xterm where to
map their windows if the WM hasn't yet started. This is solved by
exec'ing the WM early in .xsession, and waiting on its PID at the
end. If and when you close the WM, wait terminates and you fall out
of the end of .xsession, and X terminates.

That way, all these background processes get destroyed, and the same
is true if you are in the habit of using Ctrl-Alt-Backspace to kill
X rather than neatly closing the WM.

Briefly:

# ~/.xsession contents

# very early stuff
# [ … ]

if [ -x /usr/bin/fvwm ]; then
exec /usr/bin/fvwm & Wmpid=$!
else
printf '%s\n' "Error - no window manager found"
fi

# now start your clients and programs, all backgrounded with &
# [ … ]

# at the end of the file is one foreground program:

# wait for the window manager in the background to die
wait $Wmpid

# end-of-file

Cheers,
David.

Correct. Sorry, I forget that. "man crypttab".

Do this before you run update-grub.

I find tar easier to use for this, but rsync will do it, as you say,
provided one has an ext[34] partition to copy to.

Re: Late encryption of /home Partition

Hi all,

as far as I know, you also have to edit /etc/crypttab.

If one has forgotten to encrypt a partition, the easiest way is, to boot from 
a livefile system. Then backup the whole content of this partition to an 
external partition. Note, this should be a ext3 or ext4 partition, so you 
preserve all hard- and softlinks.

I suggest for using rsync doing this.

Then you can encrypt and format this partion and rsync everything back.

Doing so, I never lost data or settings.

Hope this helps.

Best regards

Hans

You can. These instructions are adapted from notes I took on a similar,
related project. You do risk making your system unbootable, and
requiring a fresh installation, so proceed with caution.

Copy everything you want to preserve from the /home partition to
somewhere else. Use tar or the like to preserve permissions.

Log out all non-root users, and umount /home.

Encrypt that partition:

cryptsetup -y -v luksFormat /dev/sdaX
cryptsetup luksOpen /dev/sdaX encryptedhome

Check your work:

cryptsetup -v status encryptedhome
cryptsetup luksDump /dev/sdaX

cryptsetup luksHeaderBackup /dev/sdaX --header-backup-file ${HOSTNAME}.$(date 
+%Y.%m.%d).luks.home.backup

Then build the LVM on top of /dev/mapper/encryptedhome:

See: https://www.linuxsysadmins.com/create-logical-volume-filesystem-in-linux/

pvcreate /dev/mapper/encryptedhome  # create the physical volume.
vgcreate ${HOSTNAME}-vg /dev/mapper/encryptedhome   # Create the volume 
group.
lvcreate -n homelv -L  ${HOSTNAME}-vg # Create a logical volume the 
size of the old /crc partition.

where  is the available space less some 20 GB so 1) you have
room to grow, and 2) a background task in Bullseye has a place to
create snapshots and fsck them.

And finally, create and (optionally) tune the file system:

mkfs.ext4 /dev/mapper/${HOSTNAME}-vg-homelv
tune2fs -i 3m -c 15 /dev/mapper/${HOSTNAME}-vg-homelv

When you've done that, mount /dev/mapper/${HOSTNAME}-vg-homelv on
/home, and restore your data.

Then edit /etc/fstab to suit. Then run update-grub. Then reboot to see
if you got everything right.

> - does it make sense to use a LVM atop? How?

It may. I mentioned two reasons to do so and leave some empty
space. It would have been better to include the encryption and LVM as
part of installing,

Re : [HS] Touches A, Q, X inopérante sous Ubuntu 20.04 depuis mise à jour

[benoit]

Perso j’essayerais en premier un test simple sur une touche au choix :

– avec xev, je regarderais le numéro de la touche du clavier, par exemple chez 
moi la touche A c’est keycode 24.

- Tu regardes avec xev ce que renvois cette touche défectueuse (toujours pour A)

keycode 24 (keysym 0x61, a)

- Si xev ne réagit pas à la pression d’une touche défectueuse t’es mal et il 
faut aller l’associer, je ne sais plus comment.

- Si tu obtiens un truc qui ne correspond pas, tu lui affectes a comme premier 
test :

xmodmap -e "keycode 24 = a"

Et puis il faut aller lire la doc de l’ordre des modificateurs tels que Shif, 
Alt, Ctrl…

Voici l’ordre dans le man xmodmap :

«Le premier keysym est utilisé quand aucune touche de modificateur n'est 
pressée en même temps que la touche, le second quand la touche majus‐cule 
(Shift) est pressée, le troisième en combinaison avec la touche Mode_switch 
(Alt Gr) et le quatrième en combinaison avec les touches majuscule et 
Mode_switch.»

Ce qui donne en suivant l’ordre indiqué dans le man :

xmodmap -e "keycode 24 = a A @"

Et si tu arrives à t’en sortir comme ça pour chaque touche défectueuse, ce 
n’est qu’une cafouille logiciel facile à régler provisoirement avec un peu de 
patience.

Pour pérenniser le résultat, tu écris chaque ligne ainsi

keycode 24 = a A @

dans le fichier $HOME/.xmodmaprc

Pour les signes, ils ont tous un nom à écrire en toute lettre.

Ex :

keycode 105 = less greater backslash

xmodmap -pk

Te donnera la liste complète.

1. En branchant (à tout moment) un clavier USB, ce dernier est totalement
opérationnel (layout français, ...). Sa présence ne change rien au
comportement des 2 autres clavier (le physique et le virtuel).

2. Grâce au clavier USB (et sa touche ESC), j'ai pu (assez difficilement)
accéder au menu Grub et choisir parmi 2 versions du noyau, chacun en 2
variantes (normal et recovery). En démarrant sur chacune des 4, le clavier
reste inopérant.

En tout cas, je suis certain que le clavier marchait normalement lundi:
sans lui, je n'aurai pas pu opérer la modification.

Late encryption of /home Partition

[Klaus Singvogel]

Hi,

I installed Debian 11 (bullseye) on a fresh PC.
I created 3 partitions: /, swap, /home.

...and forgot during installation dialog to encrypt the /home partition.

- how can I encrypt the /home partition now?
- In such a way that the password is asked for manual input during every boot?

- does it make sense to use a LVM atop? How?

I usually prefer using shell commands before graphical stuff, but will accept 
GUI tools either.

Thanks in advance.

Best regards,
Klaus Singvogel.

That would prevent the rest of the X session from running, until the
