Exim mail router - help needed


I am using Debian Bullseye with Exim 4.94 on my server (and have been for many years). I currently have a single text file listing all email address to user account mappings and an Exim router that works fine with that. However I am concerned that if I were to make a mistake in that file I could make all the lookups fail and the emails bounce.

To make it safer (and also more manageable) I've decided to split these into multiple files - one for each domain (stored by the domain name in the 'domains' sub-directory). Currently I am testing with just one test domain, but have been unable to get Exim to accept the emails sent to it ('550 Relay not permitted').

I suspect that I've made an error with the syntax around the '{/etc/exim4/domains/{$domain}}}' section (see below), but I'm unsure what. Can anyone with Exim experience advise please?

I'm also aware that the other (working) router that this is based on was written many versions ago, so if any of the below is no longer best practice/depreciated, I'd also appreciate feedback on that.

# Local domain email address handling
debug_print = "R: system_aliases (Local by Domain) for $local_part@$domain"
driver = redirect
domains = lsearch;/etc/exim4/local_split_domains
data = ${lookup{$local_part@$domain}lsearch*@{/etc/exim4/domains/{$domain}}}

file_transport = address_file
pipe_transport = address_pipe


Edit: Running Exim with debug options, I spotted this message relating to this transport: 'router skipped: domains mismatch'.

Best DE for me for Debian Testing


I'm planning on installing Debian (then upgrade to Testing). I've been using KDE Plasma for years. I liked I could do a lot of things with it, but nowadays I only replace the panel and customize icons on it. I'm thinking about MATE and Cinnamon or stay with Plasma. I'm looking forward to your recommendations.

Debian keeps crashing at random times when using 2 monitors


Ever since I added a second monitor Debian randomly crashes. The cursor is still movable between the two monitors but everything else on the screens is frozen. Is there a fix to this problem? I'm running a 2x3.2 pentium and a gt6800, Idk if it's helpful but here's the var/log/messages output from before it crashed last:

edit: as I was formatting this post it crashed again so I put the newest output aswell as the older one here https://pastebin.com/fy4Y7Crc

Trying to Disable IPv6 on Eno1


I tried to auto disable eno1 interface from having IPv6 enabled but it doesn't seem to be working.
I added the following to end of /etc/sysctl.conf:

tuna@debian:~$ sudo cat /etc/sysctl.conf | tail -n 3
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

When I reboot, and check ip addr eno1, I can see:

tuna@debian:~$ ip addr | grep inet6
    inet6 ::1/128 scope host 
    inet6 2601:482:4580:26f0::12a7/128 scope global dynamic noprefixroute 
    inet6 2601:482:4580:26f0:bcf6:ba3b:8a7b:61eb/64 scope global temporary dynamic 
    inet6 2601:482:4580:26f0:5a47:caff:fe70:b901/64 scope global dynamic mngtmpaddr noprefixroute 
    inet6 fe80::5a47:caff:fe70:b901/64 scope link noprefixroute 

When I run the following cmds I get the desired results but it doesn't appear to be persistent on reboot.

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

Upgrade Debian 9 to 10


Can I upgrade Debian 9 to 10 without losing any data or services? I am running an old service that I have to update, but it cannot be restored on a new server due to a lot of dependencies. So I have to migrate the server and install updates for the service. Any thoughts?

KDED5 Crash


The KDE Crash Handler is constantly reporting:

Executable: kded5 PID: 22,366 Signal: Segmentation fault (11)

This error more often than not happens each time i run discover but sometimes just happens randomly

I found some solution on github but seems like out of my league anyone has had this issue and managed to remove it.

Found other non solutions like disabling the system error notifications

Thanks All

i think i'm ready to use Debian!


I have been using Linux distros for a couple of years (started with Ubuntu, then back and forth a bit between Arch and Void).

My main priorities are: - simplicity (i want to really understand the system over time) - minimal (just what i need, nice and clean, related to simplicity) - can be easily made to feel and look good - good tools/setup for development (i'm a CS student) - reasonably secure by default

Just curious if those with experience feel that Debian would be a good match for me. My main gripe with Arch is just too much finicking to get what I want :)

Has something changed that prevents/restricts "arp -a/e" ability to detect new devices on the ether network?


Basically I've recently had trouble obtaining access to two devices through the wired ether for initial configuration.

In the past decades, it was just a matter of plugging it on the network then arp -a or arp -e to see MAC address and then arp -s ip/name hw mac:address.

I know Netgear has now closed down this method and want you to sign up to google tracking to download their app for the initial contact, but to encounter lack of access on a Billion router is annoying. I've been using them and this method since my internet access migrated fro serial link to adsl. Plus this method since the 80's.

The accompanying quick instruction says web browser to and I should be able to configure, but I'm getting nothing on any of lynx, dillo, falcon or firefox. No ping response either.

Arp sometimes intermittently will list a MAC address but it disappears very quickly and all I'm getting in response to 'sudo arp -s name/ip hw Mac:address' is "invalid hardware".

So checking the sticker on the product for MAC address, which is correct and same response.

Yes computer netmask is /16( to allow the 192.168.a.b to 192.168.c.d comms.

Also checked that is isn't port separation on the switch

Looking for ideas on what I've missed.

THE SOLUTION: it finally dawned after days of frustration that the problem was I/my compter actually needed to move to the /24 of the device. While I could see the device with a /16,the device can not reply as it was still in a /24.

HUH; Talking netmasks on interfaces. /24 is and /16 is

Does anyone else use Gnome Wayland in debian 11 like me?


They say wayland version in current stable is too old. But it works for me. This is from a core 2 duo laptop, it works well I might say. Some core 2 duo CPU's aren't that bad for web surfing I'd say. Mine is Intel Core2 Duo P8400, no discrete GPU. Works fine but 480p videos only on youtube.

Prevent packages from installing file in apt sources.list.d?


I use a couple of packages that install files in /etc/apt/sources.list.d/ Those packages don't refer to the GPG keys needed to authenticate repositories and conflict with entries in /etc/apt/sources.list So, every time there's an update to those packages, I have to delete the sources.list.d file it creates.

Is there any way I can prevent the creation of those files?

adduser not in the path, how can I fix it? Another question is about sharing folders mindset


It is a fresh install of Debian 11, a VM that should get to be my NAS when configured.

While setting up Samba and needing protected shares for the first time, I wanted to create a dedicated samba user. sudo adduser returns bash: adduser: command not found, but sudo /usr/sbin/adduser works fine. Does Linux have a variable similar to the Windows PATH variable and what shall I do to add folders containing commands to it?

About users, owning folders, and sharing folders

For an extended period of time, I wrongfully believed that a lower UID gives greater privileges. Since I now know that that's wrong, I came to the conclusion that I do not really understand the mindset behind owning and sharing.

Let's say, we have a folder with some content, /media/movies. The folder is owned by the username that I use. If I want to share the content of that folder, should the sharing be done by the user that owns the content, or should there be a user that shares various folders on the network? Should I change ownership of the folder to the user that shares it? Would it function if the sharing folder is not shared directly, but created a symbolic or hand link to it from another folder, let's say/shares/movies and that folder is owned and shared by the sharing user? Is there inheritance involved when the folders are linked in that way? What happens if various hard link access points have different privileges for users, is it even possible? In that regard is there a difference between symbolic and hard links?

The goal is to make a granular structure so different folders can be shared with different computers on the network (VMs, docker containers, and real users having access only to folders and data they are responsible to manage) giving them full access to those folders while keeping them invisible or read-only to all the other users.

In the above example, should I make a different user for each type of shard folder? Should I use the same password as the user password and the password for smbpasswd command?

I can read various guides and examples about specific commands to use, but I cannot learn there on what to base my decision-making process on.

Thank you

Laptop Shuts Down Instead of Rebooting After Motherboard Swap


I have a Dell Latitude 7310 with a damaged case, running Debian 11. Today, I swapped all the internals to a new case, checked the connections, and started it up. Screen, keyboard, trackpad, audio, all tested normal. The one thing that doesn't work is rebooting. When I try to restart the laptop, it just shuts down. Everything else works normally except for the restart function.

I'd appreciate any recommendations on how to sort this out.

Tasksel or DE / KDE on Previous Install


I have a Debian 12 (bookworm) system which is headless / CLI only and curious how I can get the option I am prompted with during the Debian installer that allows me to install DE/KDE Plasma which I believe is the tasksel utility or does anyone know what apt install commands I would need to provide to simulate selecting DE/KDE from tasksel util? I don't want to reinstall just to get a KDE GUI on my current system.

Hardware recommendation that works with Debian 11



I have an old laptop Acer C720P that I installed Debian 11 and it's working fine.

My problem is that I have two external monitors and the laptop has just one hdmi output.

I'm looking for an USB to VGA adapter or docking (USB A because there is no USB C output available on the laptop) to plug my second monitor and extend my desktop that works with Linux (specifically Debian).

I hope that one of you have one that can recommend.

Thank you in advance,
