I would like to know how to cleanly reset the printing system (CUPS) to its initial state. Alternatively, it may suffice for me to know how to take a "snapshot" of CUPS configuration and to roll back to it later. This is to debug the following issue, which I could reproduce on several occasions on Linux Mint 21 and on Ubuntu 22.04. After booting a freshly installed Linux Mint 21 or Ubuntu 22.04 and connecting the machine to my office LAN for the first time, network TOSHIBA e-STUDIO3015AC printers are automatically added to the list of printers as "driverless" and function properly. However, after restarting the machine and after the printers get first removed, then added back to the list, the selection of 2-sided printing in the printing dialog is getting ignored. (The printing becomes one-sided unless changed in the printer options, but if printer option is set to two-sided, then one-sided printing does not work.) I noticed that the second time the automatically generated /etc/cups/printers.conf file contains many extra lines compared to the first time the printers were used, including this one:

Option sides one-sided

I am trying to enable KASAN in my Manjaro distribution for a project, but I have no idea how to. The documentation here (https://www.kernel.org/doc/html/v4.14/dev-tools/kasan.html) says just to CONFIG_KASAN = y but I have no idea where to do and what steps should I take before that, I haven't configured the kernel before, I am a beginner. So far I have found out that I can see what configurations are done by looking at /proc/config.gz Here it says that KASAN is not enabled, but I don't know where to go from here. Should I just do an echo CONFIG_KASAN= y, or do I have to rebuild the Kernel and such? Please help me.

I have a connection via VPN with my work. I know that internet connection (for example to 8.8.8.8) goes through my work network (only when I am connected to VPN). How to configure ip tables to force that connections to internet (for example 8.8.8.8) avoid work network ? Using @Julie help in comments I did managed to discover some options: " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Nevertheless, after checking 'Use this connection only for resources...' I can't ping machines in VPN network. Can you tell me how should I deal with it ? I guess that I should click 'Add' and set: Address = address of some machine in VPN Netmask = I can get it from ifconfig (in VPN interface) Gateway - as in case of netmask Metri - I have no idea ? Am I right ?

my .bashrc has a module add shared cmsh cmd slurm line, followed only by a module load slurm. how can I find the underlying configuration of the module program and **specifically** where the modules cmsh and cmd live ? I want to find out where the path /cm/local/apps/cmd/bin/cmsh is getting added to my PATH.. which somehow gets lost after doing particular yum installs where I think some dependency items come along for the ride and upset this configuration that results in whenever a new terminal is opened that .bashrc *module add items* all fails. I assume the module add cmsh causes that PATH modification how do I find that particular cmsh.? "module" file ?

I am currently trying to set up a network bridge. Basically, I modified some files in /etc/sysconfig/network-scripts/ and messed something up to the point where I could no longer access the internet with the current ethernet connection I had. So I looked up how to reset my network settings to default and basically said to remove the files in /etc/sysconfig/network-scripts/ (I did back up the folder before doing anything) and then ran $systemctl restart NetworkManager.service Basically it just deleted files like ifcfg-eno1np0, ifcfg-eno2np1,etc. Then I restarted the computer itself and I was able to regain internet service and when I run $ifconfig it looks like all my settings are back and internet service works but when I go back to /etc/sysconfig/network-scripts/, I don't see any of the files, ifcfg-eno1np0, ifcfg-eno2p1, etc back in that directory so where are the current network settings being stored since it apparently did return back to its default state?

I created 2 virtual users for ftp (vsftpd): bholu1 and bholu2 I wanted bholu1 to have write access, access to make directory and upload permission. For that I have set up the user bholu1 as below but still he isn't able to upload file or create a directory. ( I have followed this link to achieve this) See below: I have set per-user configurability for both user :bholu1 and bholu3 ravbholua@ravi:/etc/vsftpd_user_conf$ pwd /etc/vsftpd_user_conf ravbholua@ravi:/etc/vsftpd_user_conf$ cat bholu1 anon_world_readable_only=NO write_enable=YES anon_upload_enable=YES ravbholua@ravi:/etc/vsftpd_user_conf$ cat bholu3 anon_world_readable_only=NO ravbholua@ravi:/etc/vsftpd_user_conf$ Both are able to read the login directory. But as per the configuration for bholu1, he should be able to upload as well as create a new directory but he isn't able to do so. Please see below the conf. file: ravbholua@ravi:/etc$ cat vsftpd.conf pam_service_name=/etc/pam.d/vsftpd.virtual user_config_dir=/etc/vsftpd_user_conf anonymous_enable=NO local_enable=YES #write_enable=NO #anon_upload_enable=NO #anon_mkdir_write_enable=NO #anon_other_write_enable=NO anon_world_readable_only=YES chroot_local_user=YES guest_enable=YES guest_username=virtual listen=YES listen_port=10021 pasv_min_port=30000 pasv_max_port=30999 ravbholua@ravi:/etc$ It doesn't make any difference even if I uncomments all lines which are commented as shown above in the config. file.

I don't mean the files under /etc/ufw/, as best I can tell, because I have rules with comments in them and those comments do not exist in any file in that directory. The .rules there are the derived commands for iptables, and their comments contain only the app name. Say ufw status numbered shows this rule:

To                         Action      From
     --                         ------      ----
[ 1] MyAppName                  ALLOW IN    Anywhere                   # myuniquecomment

MyAppName is defined under /etc/ufw/applications.d/ but I can't find myuniquecomment except in the output of ufw commands. So where are the originals located?

### Issue I want to troubleshoot problems with my bash environment, therefore I would like to study exactly which config files bash is opening and when. ### What I tried

bash --verbose | tee txt.tmp

^^^ this doesn't really work, as bash is creating a sub-shell inside the current one. ### PS I feel like the answer to this must be something extremely trivial, yet this is the first time I haven't been able to pipe terminal output to a file, so it strikes me, and I have no idea how I would do it differently!

I am running a closed-source Java application in the Openbox window manager. The application runs, but the application's main window is displayed without window decorations. Presumably, the application itself is requesting that its main window be displayed without window decorations. I would prefer that the application's main window have window decorations. My question is: Is it possible to forcefully add window decorations to an already created and displayed window? If not, why not? Possibly relevant X properties:

$  obxprop  |  grep  DEC
_OL_DECOR_DEL(ATOM) = _OL_DECOR_HEADER, _OL_DECOR_RESIZE, _OL_DECOR_CLOSE
_NET_WM_ALLOWED_ACTIONS(ATOM) = _NET_WM_ACTION_CHANGE_DESKTOP, _NET_WM_ACTION_CLOSE, _NET_WM_ACTION_MOVE, _NET_WM_ACTION_MINIMIZE, _NET_WM_ACTION_RESIZE, _NET_WM_ACTION_FULLSCREEN, _NET_WM_ACTION_MAXIMIZE_HORZ, _NET_WM_ACTION_MAXIMIZE_VERT, _NET_WM_ACTION_ABOVE, _NET_WM_ACTION_BELOW, _OB_WM_ACTION_UNDECORATE

I have tried the following: 1. Selecting Un/Decorate in the window’s Openbox client menu. 2. Setting the following in Openbox’s rc.xml file.

yes

3. Removing the _OL_DECOR_DEL property with xprop -remove _OL_DECOR_DEL. None of the above have had any effect. The window refuses to display decorations.

## Problem Context: Fedora CoreOS operating system (read-only root filesystem). I'm trying to add myuser to group dialout so I can access /dev/ttyS1 via its group owner. However, during first boot, Ignition phase keeps failing. **Questions**: - How can I add a custom user to group dialout? - How is it possible that it fails with the 2 error messages below ("group doesn't exist" and "group already exists")?

Ok, so I've been searching the web for solutions to this problem with no answers seeming to work for me. Hopefully someone can help me. I'm only trying to configure the OpenVPN Client. I'm running CrunchBang Linux 3.2.0-4-amd64 Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux and I just switched over to using systemd. The changeover went smooth enough but now I can't get my OpenVPN client to come up using systemd I've tried following these configuration tutorials, but nothing works. - http://fedoraproject.org/wiki/Openvpn - http://d.stavrovski.net/blog/how-to-install-and-set-up-openvpn-in-debian-7-wheezy - And looked at a bunch of other different guides. I can bring up the tunnel from the command line with openvpn /etc/openvpn/vpn.conf. So I know the config file is good, it was working with sysvinit just fine so I'm not surprised. I then attempt to just do a status with systemctl status openvpn@vpn.service resulting in: $ sudo systemctl status openvpn@vpn.service openvpn@vpn.service Loaded: error (Reason: No such file or directory) Active: inactive (dead) I realized that I need to do some setup for services. I want to be prompted for a password so I followed this guide to create an openvpn@.service in /etc/systemd/system/. But restarting the OpenVPN service still doesn't prompt for a password. $ sudo service openvpn restart [ ok ] Restarting openvpn (via systemctl): openvpn.service. The Fedora tutorials go through the steps of creating symbolic links, but don't create any of the .service files in the walk-throughs. What piece am I missing? Do I need to create an openvpn@vpn.service? If so, where exactly do I place it? I feel like it shouldn't be this difficult, but I can't seem to find any solution that works for me. I'm happy to provide any more information that's needed. ## Solution -rw-r--r-- 1 root root 319 Aug 7 10:42 openvpn@.service [Unit] Description=OpenVPN connection to %i After=network.target [Service] Type=forking ExecStart=/usr/sbin/openvpn --daemon ovpn-%i --status /run/openvpn/%i.status 10 --cd /etc/openvpn --config /etc/openvpn/%i.conf ExecReload=/bin/kill -HUP $MAINPID WorkingDirectory=/etc/openvpn [Install] WantedBy=multi-user.target openvpn@.service (END) Symlink: lrwxrwxrwx 1 root root 36 Aug 7 10:47 openvpn@vpn.service -> /lib/systemd/system/openvpn@.service **Prompt For Password** ----------------------- Everything is working now, except for being prompted for a password to connect.

- How can I make that FTP server daemon running without errors? - What's wrong with the configuration file?

Apologies in advance if my terminology is not on par. So I've just setup my work dev machine successfully on Fedora Workstation with Nginx and multiple PHP versions (using Remi Collet's Software Collection). I have PHP-5.6.30 listening on Port 9056 and PHP-7.0.19 listening on Port 9070. This works perfectly. This morning I decided to try running both PHP instances using FPM Sockets, which initially worked until I restarted the PHP-FPM service (this resulted in a *502 Bad gateway* in the browser, and *(13) Permission Denied* error in the nginx error.log). So using PHP5.6 as an example ... when I first started the php56-php-fpm service which generated /opt/remi/php56/root/var/run/php-fpm/www.sock, I changed the generated www.sock file's user and group to nginx:nginx. After restarting php56-php-fpm I learned that www.sock was being reset to root:root. Now granted I won't be restarting FPM constantly, but there must be a way to set some defaults on the .sock file?? My fpm conf files looks like this: - **/opt/remi/php56/root/etc/php-fpm.d/www.conf**: https://pastebin.com/EasyHyEs - **/etc/opt/remi/php70/php-fpm.d/www.conf**: https://pastebin.com/dhT8AEJK - **/etc/nginx/nginx.conf**: https://pastebin.com/tMuAFnGM - **/etc/nginx/conf.d/default.conf**: https://pastebin.com/UjkrcaYw I realise that this sounds like a pain to get working correctly, considering that I am just doing this for local development, ***and*** that I did have this all working correctly using ports 9056 & 9070. But I've read that there are some speed benefits using sockets versus TCP, and anything that would speed up my local dev environment is worth making the effort for. So my questions: 1. What in my config is incorrect that is causing www.sock to be reset to root:root after restarting the respective FPM service? 2. Is it really worth moving away from ports in favour of sockets? 3. [slightly off-topic]: using Remi Collet's software collection, I see that the 2 PHP packages install to different locations: /opt/remi/php56 and /etc/opt/remi/php70 ... for the purpose of consistency, should I consider moving either one of these into a more common location? Thank you

I have been trying since about a week with installing arch and Qtile, but the problem is that everytime I install it, even if I change the file default_config.py with what i want, when i reboot it shows the default config of qtile. I don't know why it happens cause i tried compiling the file config.py and it doesn't show a problem on sintaxis nor anything else. I leave here my config: import os import re import json import socket import subprocess from os import listdir from os import path from typing import List # noqa: F401 from libqtile.command import lazy from libqtile import layout, bar, widget, hook from libqtile.config import Key, Screen, Group, Drag, Click qtile_path= path.join(path.expanduser("~"), ".config", "qtile") icons_path= path.join(qtile_path, "icons") img = {} #

^\_^ ### Synopsis I want to specify my primary monitor using system-wide X11 configuration files, but my present configuration files don't seem to do anything! 0_0 ### My situation I'm coming from the same place as this question here: https://unix.stackexchange.com/questions/565553/why-doesnt-x11-set-the-only-monitor-as-primary-by-default Namely, I need the only monitor I have connected to be recognized as my primary monitor so that my tray icons in i3 work. That said, I don't want to solve this using using xrandr, because I'm trying to use as much as possible the same dotfiles on two different machines which have different hardware configurations. Therefore, I would like to solve this using the system-wide X11 configuration files. However, it doesn't seem to work as expected. :o ### My present setup At present I have no xorg.conf file, and I do have a xorg.conf.d/10-monitor.conf, the contents of which (following [this Arch Linux wiki page](https://wiki.archlinux.org/index.php/Multihead#Configuration_using_xorg.conf)) are here:

Section "Monitor"
    Identifier  "HDMI2"
    Option      "Primary" "true"
EndSection

In light of this configuration file, here is my xrandr output for a fresh X session:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
DP1 disconnected primary (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 480mm x 270mm
   1920x1080     60.00*+
   1600x1200     60.00  
   1680x1050     59.88  
   1400x1050     59.95  
   1600x900      60.00  
   1280x1024     75.02    60.02  
   1440x900      59.90  
   1280x800      59.91  
   1152x864      75.00  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   640x480       75.00    72.81    66.67    59.94  
   720x400       70.08  
HDMI3 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

As you can see, despite having specified HDMI2 in the configuration files as my primary monitor, DP1 is set as the primary. ### Stuff I've tried I've verified that my configuration file is being processed by X11 by introducing typos and observing that X11 fails to launch due to errors. I've tried placing the configuration file above in /etc/X11/xorg.conf instead of /etc/X11/xorg.conf.d/10-monitor.conf. I've tried including the following in an attempt to specify the default primary monitor as not primary:

Section "Monitor"
    Identifier  "DP1"
    Option      "Primary" "false"
EndSection

I've tried launching with the default xorg.conf generated by X -configure alongside my 10-monitor.conf. ### Miscellaneous information

When I run neofetch, I get the first line containing :

fauve@katioucha

I can silent it by neofetch --disable title, it’s fine. But my goal is to hide the user and keep the hostname. I found [here](https://github.com/dylanaraps/neofetch/wiki/Customizing-Info#display-the-current-weather) how to configure the infonames to show, but theire is no infoname for the “machine name”. host exist but in the neofetch terminology host refer to the model of the machine not to the system name. Also title refer to @ but I didn’t found a way to just display machine name. So, how can I display in one line just the machine name in neofetch?

In Qutebrowser, I try to create the following behavior: tab-close, or at least the action associated with it (i.e., pressing d), should, in all situations where more than one tab is open, close the current tab, as it already does. However, if the window contains only one tab, it should close that tab and open the default tab in its place. Basically, like Firefox does. I made many tries in config.py, creating a smart_tab_close() function which gets the number of opened tabs, but I failed. So how to make Qutebrowser act like that?

I just moved an old buildroot folder from an old VM to a newer one to consolidate. I thought that simply moving the folder, along with any dependent folders, and making the appropriate path/name changes would be all that is required to get it up and running in the new VM. Unfortunately, this appears to not be the case as I am greeted with the following error upon attempting to build in this new VM: # # configuration written to /home/mirion/mirion/buildroot-2013.05/.config # /usr/bin/make -j5 HOSTCC="/usr/bin/gcc" HOSTCXX="/usr/bin/g++" silentoldconfig make: Entering directory '/home/mirion/mirion/buildroot-2013.05' BR2_DEFCONFIG='' KCONFIG_AUTOCONFIG=/home/mirion/mirion/buildroot-2013.05/output/build/buildroot-config/auto.conf KCONFIG_AUTOHEADER=/home/mirion/mirion/buildroot-2013.05/output/build/buildroot-config/autoconf.h KCONFIG_TRISTATE=/home/mirion/mirion/buildroot-2013.05/output/build/buildroot-config/tristate.config BUILDROOT_CONFIG=/home/mirion/mirion/buildroot-2013.05/.config /home/mirion/mirion/buildroot-2013.05/output/build/buildroot-config/conf --silentoldconfig Config.in *** Error during update of the configuration.
