Default Permissions

[inukaze]

This is a re-post i do too in -> https://www.linuxquestions.org/question ... ost6578470

Hi there again, look, yesterday, making some test on Porteus USB Live Mode.
Just for start Cisco Packet Tracer 8.0 bypassing Login Window.

I do the follow

01 - I create a group called "sin-internet"

Code: Select all

groupadd sin-internet

02 - Use iptables for make the group "sin-internet" does not have internet access

Code: Select all

iptables -A OUTPUT -m owner --gid-owner sin-internet -j DROP
ip6tables -A OUTPUT -m owner --gid-owner sin-internet -j DROP
iptables-save
ip6tables-save

03 - i for the restart of ethernet device, eth0 :

Code: Select all

su -c 'IDR="eth0" ; \
/etc/rc.d/rc.networkmanager stop ; /etc/rc.d/rc.inet1 stop ; /etc/rc.d/rc.inet2 stop ; /etc/rc.d/rc.inetd stop ; \
/etc/rc.d/rc.inet1 start ; /etc/rc.d/rc.inet2 start ; /etc/rc.d/rc.inetd start ; /etc/rc.d/rc.networkmanager start ; \
ip link set "$IDR" down ; ip link set "$IDR" up' root

04 - in the file /etc/sudoers i add the follow

Code: Select all

## Same thing without a password
# %wheel ALL=(ALL:ALL) NOPASSWD: ALL
%wheel    ALL=(:sin-internet)      NOPASSWD: ALL
%sudo     ALL=(:sin-internet)      NOPASSWD: ALL

i save, and exit

05 - Add the user to groups wheel and sin-internet, and Change the group in all file and sub-folder inside the path "/opt/pt"

Code: Select all

sudo gpasswd -a "$USER" -g wheel
sudo gpasswd -a "$USER" -g sin-internet
cd /opt/pt
sudo chown "$USER:sin-internet" -R *

06 - Test the cisco packet tracer does show login window :

Code: Select all

sudo -g sin-internet /opt/pt/packettracer

07 - If all works fine, in the /etc/rc.d/rc.local i add the follow lines :

Code: Select all

Directorio="/opt/pt"
if [ -d "$Directorio" ]; then
	cd "$Directorio"
	iptables -A OUTPUT -m owner --gid-owner sin-internet -j DROP &> /dev/null
	iptables-save &> /dev/null
	ip6tables -A OUTPUT -m owner --gid-owner sin-internet -j DROP &> /dev/null
	ip6tables-save &> /dev/null
	$(chown "guest:sin-internet" -R *) &
fi

But the thing was, before i forgot add the line

Code: Select all

cd "$Directorio"

Then the command

Code: Select all

(chown "guest:sin-internet" -R *)

was applied to all mounted partitions like the own Porteus USB, Salix 15.0, Slackware(64) 15.0

Then i not had idea which are the default permissons for entere system and what things need very specific permissions, like : lightdm, lxdm, xfce, xfce-sessions, libblock

basically the things control the session, and allow common user things like use power down, restart. the thing controls which partitions are in use, the automount of flash usb pendrive.

during boot i can see this message

Mon Jun 23 18:17:14 2025: ** (lightdm:1286): WARNING **: 18:17:14.815: Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute program org.freedesktop.Accounts: Permission denied

i don0t know if was a good idea follow this information or use the commands on this article -> https://stackoverflow.com/questions/405 ... g-my-files

i really dont want reinstall from scratch salix neither slackware.

[inukaze]

In first instance the follow works :

Like root

Code: Select all

slapt-get -i --reinstall lightdm libblockdev xdg-desktop-portal xdg-desktop-portal-gtk accountsservice dbus desktop-file-utils eudev libevdev p11-kit pkgconf polkit udisks udisks2 upower wpebackend-fdo xdg-user-dirs xdg-utils xdgmenumaker ; ldconfig

i got again in thunar show partitions like "proc" i solved with :
like root

Code: Select all

slapt-get --remove udisks udisks2 libblockdev gvfs
rm -rf /etc/libblockdev
rm -rf /etc/udisks2
slapt-get -i udisks2 libblockdev gvfs; ldconfig

Some applications like Brave Browser does not stop asking for keyring password and i never use that, i solve with
Like common user :

Code: Select all

rm ~/.local/share/keyrings/*
sudo slapt-get --remove gnome-keyring ; sudo ldconfig

In second instance with another script again i basically get the same result produced by :

Code: Select all

chmod 755 -R / ; chown root:root /

i know the default common user permissions are (on home of user):

Code: Select all

chmod 755 /home/inukaze ; cd /home/inukaze
chmod 644 .dmrc .ICEauthority .face .face.icon
chmod 600 .Xauthority

chmod -R 700 .cache .dbus .gconf .local
chmod -R 755 .config .mozilla .linuxmint 

chmod -R 755 Descargas Downloads 
chmod -R 755 Desktop Escritorio 
chmod -R 755 Documentos Documents
chmod -R 755 Imágenes Pictures
chmod -R 755 Música Music
chmod -R 755 Plantillas Templates
chmod -R 755 Público Public
chmod -R 755 Vídeos Videos

In the LinuxQuestions Forum the user "Petri Kaukasoina" give me this link -> https://slackware.osuosl.org/slackware6 ... NIFEST.bz2 and a link for script -> https://slackware.nl/people/alien/tools ... anifest.sh

Before i use that file and that script i try from Porteus Live USB

Code: Select all

mkdir -p /mnt/sda3
mount /dev/sda3 /mnt/sda3
mount --rbind /dev/pts /mnt/sda3/dev/pts
mount --rbind /dev /mnt/sda3/dev
mount --rbind /proc /mnt/sda3/proc

mount --make-rslave /mnt/sda3/proc
mount --make-rslave /mnt/sda3/sys
mount --bind /etc/resolv.conf /mnt/sda3/etc/resolv.conf
chroot /mnt/sda3

root[~]#

i restart and the thing goes wrong, because the 32 Bits mode not load all things fine like before, i repeat the steps for mount and use chroot but i follow the steps of "Dirty" mode of multilib -> https://docs.slackware.com/slackware:multilib

and that fix the system enter in 64 Bits mode instead 32 Bits mode.

[inukaze]

in second instance, i use the script requiere the MANIFEST file, after around 9 hours, and i just the every line was "usr/doc" i just cancel that some minutes ago, i restart the system to check if i got good results and looks like partially yes

The things i notice i no had done on Salix
A - Set the tty resolution to 1024x768x16bpp -> i use with links web browser, i don't know why nobody had create a mode using framebuffer to make something similar to desktop environment, like was windows 3.x, and apps looks like graphical but really does not be graphicals apps XD.

B - Install apps does not need graphical env, For example dosbox-0.74, vlc ( for use nvlc just for hear music, because i not have framebuffer access on nvlc to watch videos ).

i need research again which apps can be used without graphical system for
1 - web navigatiion (if possible email client, some years ago "elinks" support that)
2 - file explorer -> mc came with salix excelent
3 - gpm for use mouse in tty ( for some unknow reason when i install from repositories never works ) the rc.gpm file

i need manually launch something like

Code: Select all

/usr/sbin/gpm -m /dev/input/mice -t ps2 

4 - i need recompile again things like "ppsspp" and "retroarch" for "No X" mode, well i don't know if versions superiors of ppsspp v1.15 still supports that and retroarch the last time i do that was in the version 1.09.2

C - DOSBox-0.74 can't start show a message :

DOSBox version 0.74-3
Copyright 2002-2019 DOSBox Team, published under GNU GPL.
---
Exit to error: Can't init SDL Unable to open mouse

i try to solve by this way :
1 - Create a group called mouse

Code: Select all

groupadd -f mouse

2 - Add my user to group mouse

Code: Select all

gpasswd -a inukaze -g mouse

3 - i create the file /etc/udev/rules.d/75-mouse.rules with the follow content

KERNEL=="event?" NAME="input/%k", MODE=0660, GROUP="mouse"
KERNEL=="mouse?" NAME="input/%k", MODE=0660, GROUP="mouse"
KERNEL=="mice" NAME="input/%k", MODE=0660, GROUP="mouse"

4 - Reload udev :

Code: Select all

udevadm control --reload-rules && udevadm trigger

well if you can use "sudo" the system loads dosbox

The things was i do recently
1 - i had reinstall nvidia drivers with compat32
2 - i reinstall lightdm
3 - /etc/rc.d/rc.4 can't start lightdm correctly ( by the moment i don't know why the Xorg.0.log just say GPU deleted )
4 - i edit /etc/inittab and change the start mode from 4 to 3, save and restart
5 - if i use root like username not ask for password just enter, with my common user "inukaze" ask for password
6 - salix does not allow use startx
7 - if i use startx with my common user, try to start the grafical system but hang up entire pc
8 - in this last try i use "startxfce4" instead "startx" and by the moment i am using this
9 - by the moment i can use "sudo" or "su"
sudo

sudo: /usr/bin/sudo debe ser propiedad del uid 0 y tener el bit setuid establecido

su

Contraseña:
su: El servicio de autenticación no puede recuperar la información de autenticación

i will go to try

Code: Select all

echo "$(grep -v "usr/src" MANIFEST.ORIGINAL)" > M1
echo "$(grep -v "usr/doc" M1)" > M2
echo "$(grep -v "include" M2)" > M3
echo "$(grep -v "locale" M3)" > M4
echo "$(grep -v "icons" M4)" > M5
echo "$(grep -v "pixmaps" M5)" > MANIFEST

to try to use script again, but i just wait does not take 24hours XD. with that commands i reduce the file MANIFEST from almost 64MB to almost 25MB

[inukaze]

Some fix can be useful :

sudo: /var/db/sudo/lectured is world writable

Code: Select all

chmod 700 /var/db/sudo/lectured
chown root:root /var/db/sudo/lectured

sudo: /usr/bin/sudo debe ser propiedad del uid 0 y tener el bit setuid establecido

Fix ( you can put this on /etc/rc,d/rc.local during boot for ever fix during booting ) :

Code: Select all

chmod 4755 /usr/bin/sudo
chown root:root /etc/sudoers
chown root:root /usr/bin/sudo
chown -R root:root /usr/bin/sudo
chmod -R a=rx,u+ws /usr/bin/sudo

su: El servicio de autenticación no puede recuperar la información de autenticación

Fix

Code: Select all

sudo packagemanager --install --reinstall shadow ; sudo ldconfig

locate: no se puede abrir `/var/lib/mlocate/mlocate.db': Permiso denegado

Fix

Code: Select all

sudo chmod 644 /var/lib/mlocate/mlocate.db

[inukaze]

umm i don't know if now a startup script called "cgroups" is working, but i can't use "video acceleration" (dri) with "nvidia" properaty driver, the games instead 60 FPS like Starcraft64 on retroarch, are in 2-3 FPS

i already had re-installed nvidia driver, from txz package i produce before with 32 Bits compat enabled.

with my user on a terminal window :

Code: Select all

glxinfo

name of display: :0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:

Why ? must be NVIDIA, i had already installed the propetary drivers, and my /etc/X11/xorg.conf content is

NOTE : with nvidia propetary drivers, the most common you can't use the "VirtualGL" / "vgl" for virtual machines.

Is because i use "starxfce4" from my user cli login instead "startx" ( this hang up entire pc ), and lightdm does not working


umm the change permissions with chmod and/or chown on / produce a mess on GNU/Linux system i think the chmod and/or chown,chgrp on / partition, must be protected, when the user try, wait 10 seconds for an answer, is the user does not input nothing the default answer must be no

another thing can do a mess is when the free space says 0 Bytes or -1 Byte, some years ago the unique solution i found was do a medium level format using "Victoria 5.02 for Windows XP" xD the rest i can't do nothing on that disk xD.

[inukaze]

Finally the script for fix permissions finish the job. with my edited version of MANIFEST around 25MB, take almost 12 hours to finish.


Well for fix nvidia i have the packages on the root home folder, and i just do the follow like root :

removepkg nvidia-legacy390-kernel-390.157_5.15.161-x86_64-2_SBo.tgz
removepkg nvidia-legacy390-driver-390.157_multilib-x86_64-7_SBo.tgz
echo -ne "blacklist nouveau\noptions nouveau modeset=0" | tee /etc/modprobe.d/BLACKLIST-nouveau.conf
installpkg nvidia-legacy390-kernel-390.157_5.15.161-x86_64-2_SBo.tgz
installpkg nvidia-legacy390-driver-390.157_multilib-x86_64-7_SBo.tgz

Code: Select all

packagemanager --remove lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings

rm -rf /var/log/lightdm
rm -rf /var/lib/lightdm
rm -rf /var/lib/lightdm-data
rm -rf /var/lib/gdm
rm -rf /var/cache/lightdm
rm -rf /usr/share/polkit-1/rules.d/42-lightdm.rules

packagemanager --install lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings

i test first lightdm works correctly before edit /etc/inittab to switch autostart in mode 3 for mode 4

Code: Select all

chmod +x /etc/rc.d/rc.4
sh /etc/rc.d/rc.4

Works fine, restart entire system , and now i get my system back

i edit my /etc/inittab i do the follow edits :

For automatically reach graphical env :

Code: Select all

id:4:initdefault:

autologin my user on tty6, Sometimes i do script for run games on this tty, specially windows games in 16 Bits, this prevent Xorg hangs.

Code: Select all

c6:1235:respawn:/sbin/agetty -a inukaze 38400 tty6 linux

But the before needs too, the follow thing

Code: Select all

echo 'allowed_users=anybody' | sudo tee /etc/X11/Xwrapper.config

to allow start graphical env in another tty for my user

[inukaze]

In resume all things i do for fix :

With root user :

1 - Download this file :

Maybe this helps you:
https://slackware.osuosl.org/slackware64-15.0/slackware64/MANIFEST.bz2

2 - Extract the "MANIFEST" file and rename to "MANIFEST.ORIGINAL" and do the follow in a terminal :

Code: Select all

echo "$(grep -v "usr/src" MANIFEST.ORIGINAL)" > M1
echo "$(grep -v "usr/doc" M1)" > M2
echo "$(grep -v "include" M2)" > M3
echo "$(grep -v "locale" M3)" > M4
echo "$(grep -v "icons" M4)" > M5
echo "$(grep -v "pixmaps" M5)" > MANIFEST

This reduce filesize from almost 64MB to 25MB aprox.

3 - Download the script for use the edited MANIFEST File :

Try this:
https://slackware.nl/people/alien/tools/restore_fileperms_from_manifest.sh

i put the files "restore_fileperms_from_manifest.sh" and edited "MANIFEST" on " / " in the root partition i want to fix file permissions, on my pc takes around 12 hours to finish that job

i edit the file /etc/inittab and chage the init mode from 4 to 3, and i add autologin for my user on tty6

id:3:initdefault:

c6respawn:/sbin/agetty -a inukaze 38400 tty6 linux

save the changes and exit

i remove the execution permission of ec.4 for disable automatic start the graphical env.

Code: Select all

chmod -x /etc/rc.d/rc.4

in this point i had restart the entire pc, and login like root on tty1, on the rest of tty from 2 to 6 i login with my user "inukaze"

in tty2, i try to run dosbox but appears the message

DOSBox version 0.74-3
Copyright 2002-2019 DOSBox Team, published under GNU GPL.
---
Exit to error: Can't init SDL Unable to open mouse

i try solve making the follow, in tty1 (like root)

Code: Select all

groupadd -f mouse
gpasswd -a inukaze -g mouse

i manually add the follow lines in /etc/udev/rules.d/75-mouse.rules
[quote]KERNEL=="mice" NAME="input/%k", MODE=0660, GROUP="mouse"
KERNEL=="mouse?" NAME="input/%k", MODE=0660, GROUP="mouse"
KERNEL=="event?" NAME="input/%k", MODE=0660, GROUP="mouse"[/quote]

i restart again, i see the dmesg output message : 
"Error in line 1 /etc/udev/rules.d/75-mouse.rules unexpected "," in character 32"
"Error in line 2 /etc/udev/rules.d/75-mouse.rules unexpected "," in character 34"
"Error in line 3 /etc/udev/rules.d/75-mouse.rules unexpected "," in character 34"

i edit again /etc/udev/rules.d/75-mouse.rules and i put the follow :
[quote]SUBSYSTEM=="input", ATTRS{name}=="ImPS/2 Generic Wheel Mouse", MODE="0666", ENV{ID_INPUT_MOUSE}="1"

#ATTRS{name} -> must be extract from output of commands :
# cat /proc/bus/input/devices		#Read and determine which event is your mouse
# Notice in the output lines like :
# I: Bus=0011 Vendor=0002 Product=0005 Version=0000
# N: Name="ImPS/2 Generic Wheel Mouse"	#This is the line you looking for.
# P: Phys=isa0060/serio1/input0
# S: Sysfs=/devices/platform/i8042/serio1/input/input4
# U: Uniq=
# H: Handlers=mouse0 event9 
# B: PROP=1
# B: EV=7
# B: KEY=70000 0 0 0 0
# B: REL=103


#KERNEL=="mice", MODE=0660, OWNER="root", GROUP="mouse"
#KERNEL=="mouse?", MODE=0660, OWNER="root", GROUP="mouse"
#KERNEL=="event?", MODE=0660, OWNER="root", GROUP="mouse"[/quote]

i restart entire pc again, i try again, dosbox ran, for few minutes
but when i put keys, the keyboard print wrong characters, and after hang up entire pc
i need a better solution for that XD, i restart, and comment out all lines by now


Again i restart the entire pc but this time

In the tty1 i let the script "restore_fileperms_from_manifest.sh" working
[code]cd /
sh restore_fileperms_from_manifest.sh

meanwhile the script do it job, i remember some years ago i learn on Debian 8 a lot of things of working without graphical session the first things i do its check if i had the follow programs

mc -> file manager
dosbox -> msdos emulator

retroarch -> i have the flatpak, but this version requiere graphical env to work, when i compile manually i ever put does not requiere X

ppsspp -> the same case of retroarch

links (version 2) or links2 -> web browser, elinks works great with email client like gmail before, but is not working on my Slackware or salix

vlc -> the "nvlc" works for hear music, because players like cmus or moc not wanna work on my slackware and/or salix

i ran a custom compile version of dosbox like root user and that works for let me allow play some games, meanwhile the script working fixing file permissons, the thing i not remember is my custom version start graphical env without nothing and start dosbox preconfigured XD, play Supaplex after Eye Of Beholder ever is fun.

meanwhile i play on dosbox, i think i not have configured the programs to use on just "tty" mode, without Xorg / Wayland
like i do when i use Slackware(64) 14.2 things like

A - Enable Framebuffer access for video, to enable resolutions like 1024x768x16bpp on tty
B - Custom compilations of programs for use without graphical env like : retroarch, ppsspp, mplayer

C - Custom things for "mc" program to enable file associations like : image files using "zgv" image viewer, or test if the custom script for download youtube video and use mplayer in sdl mode to play it

Why never someone had create something similar to Windows 3.X, for GNU/Linux framebuffer, to looks like a graphical env but really does not its, links web browser works and look nice in framebuffer video mode.


4 - Fix sudo and su :

sudo: /var/db/sudo/lectured is world writable

Code: Select all

chmod 700 /var/db/sudo/lectured
chown root:root /var/db/sudo/lectured

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
chmod 4755 /usr/bin/sudo
chown root:root /etc/sudoers
chown root:root /usr/bin/sudo
chown -R root:root /usr/bin/sudo
chmod -R a=rx,u+ws /usr/bin/sudo[/code]

In anothers distros is possible you need this instead :

Code: Select all

chown root:root /usr/lib/sudo/sudoers.so
chmod -R a=rx,u+ws /usr/lib/sudo/sudoers.so
chown -R root:root /usr/lib/sudo/sudoers.so
chmod 4755 /usr/lib/sudo/sudoers.so

su: The authentication service cannot retrieve authentication information

Code: Select all

packagemanager --install --reinstall shadow

locate: cannot open `/var/lib/mlocate/mlocate.db': Permission denied

Code: Select all

sudo chmod 644 /var/lib/mlocate/mlocate.db

5 - Remove, Install and/or reinstall packages : i already have packages with nvidia propetary drivers with compat32 enabled.

Code: Select all

packagemanager --remove udisks udisks2 libblockdev gvfs lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings gnome-keyring
