+## Problème d'affichage et de droits d'accès avec l'utilisateur GLPI
+
+### Description du problème
+
+En étant connecté avec l'utilisateur `glpi`, il peut y avoir différents dysfonctionnements/bugs d'affichage:
+
+- Dans Administration > Entités: seule l'entité racine est visible
+- Après avoir installé le plugin Tag (*Gestion des tags*) une erreur concernant les permissions est affichée et il est impossible d'ajouter des tags
+
+En se connectant avec un autre utilisateur ayant les droits super-admin, les sous-entités sont affichées et le plugin Tag est accessible.
+
+### Comment reproduire le problème
+
+Installer une nouvelle instance de GLPI sans aucune autre configuration
+
+### Résolution du problème
+
+Deux manipulations distinctes:
+
+#### Pour permettre à glpi d'ajouter des tags
+
+1. affecter l'habilitation *super-admin* à un autre utilisateur (pour l'entité racine) (par exemple `user1`)
+2. se connecter avec cet utilisateur
+3. vérifier que l'utilisateur `user1` a bien les droits super-admin
+4. supprimer l'habilitation super-admin de l'utilisateur `glpi`
+5. se connecter avec `glpi` et vérifier la suppression des droits
+6. se connecter avec l'utilisateur `user1` et ré-affecter les droits super-admin à l'utilisateur `glpi`
+
+Vérifier alors que l'utilisateur `glpi` peut ajouter des tags.
+
+
+#### Pour permettre à glpi de voir les sous-entités
+
+1. Aller dans Entités > Entité Racine > Règles
+2. Cliquer sur la règle `Root` (règle normalement créée automatiquement à l'installation de GLPI)
+3. Aller sur *Critère* et cliquer sur `Ajouter un nouveau critère`
+4. Sélectionner comme critère "Type d'authentification"
+5. Sélection `Est`
+6. Choisir "Authentification sur la base de données GLPI"

+When I start a VPN connection, a new default route is added on the utun0 interface:
+
+```
+Destination        Gateway            Flags        Refs      Use   Netif Expire
+default            utun0              UCS            21        0   utun0
+default            192.168.43.1       UGScI          14        0     en1
+```
+
+I'd like to get rid of the default/utun0 route. When using route with the -ifscope modifier, I get the following error:
+
+```
+$ sudo route delete -ifscope utun0 -net 0.0.0.0
+route: writing to routing socket: not in table
+delete net 0.0.0.0: not in table
+```
+
+What am I doing wrong? What's the correct syntax of the route command in order to delete the default route?

+I know it's late, but I'd like to know what kind of VPN you're using.
+
+I've had this problem with Cisco Anyconnect VPN.
+
+Not seeing the same error as you, but the command would appear to execute, but the routing table would still look the same.
+
+I believe Cisco AnyConnect locks the routing table in some way so that it cannot be modified.
+
+If this isn't Cisco AnyConnect, it may do something similar. I haven't found any documentation on it, but that's the conclusion I've come to from my testing.
+
+I've found this also appears to apply on Windows.

+### How to add and delete Static Routes on macOS (persistently)
+
+#### Problem
+
+I have several networks at home, including 192.168.1.0/24 and 192.168.2.0/24. A problem occurred when I connected to a VPN site because it gives a route with 192.168.2.0/23. So my traffic on 192.168.2.0/24 routed through the VPN tunnel instead of my internal home network.
+
+Therefore, I need to add a static route on my MacBook Pro.
+
+#### Solution
+
+Here is how to add or delete a static route on macOS.
+
+As you see below, I received the 192.168.2.0/23 route from the VPN, and it routes through the tunnel interface, utun3. First, disconnect the VPN and add a static route as described below.
+
+### To view the routing table:
+
+You can use the following command "
+
+" and use '
+
+' to filter with a specific network on the Terminal.
+
+#### ▶ Method 1. Add a static route temporarily
+
+### To add a static route:
+
+### To verify the route you added:
+
+Now, 192.168.2.0/24 routes through my Ethernet interface, en10.
+
+### To delete a static route:
+
+#### ▶ Method 2. Add a static route persistently
+
+The above route will be gone if you reboot your Mac. You need to add a static route permanently if you want to keep this route persistently.
+
+### To verify the route your interface:
+
+### To list devices (network adapters):
+
+Or
+
+### To list devices with the interface number:
+
+I prefer this command because it also shows the ethernet number (e.g. en10).
+
+### To add a static route permanently:
+
+### To verify the route you added:
+
+### To delete this permanent route:
+
+Use
+
+without the address, netmask, and gateway.
+
+### To see all commands:

+
+Thanks for this post. It was very useful. Just my additional 2 cents - 
+
+We can also get the configured permanent static routes using: networksetup -getadditionalroutes "USB 10/100/1000 LAN" .
+
+Also, if we want to add multiple routes permanently then we can add additional tuples     on the same command. Eg., sudo networksetup -setadditionalroutes "Wi-Fi" 192.168.230.0 255.255.255.0 192.168.20.82 192.168.68.0 255.255.255.0 192.168.20.82

+
+I'm doing something wrong. I work from home and connect to my company's VPN. I need an SMB connection to our file server, which has the IP 192.168.2.108. VPN My network at home has the IP 192.168.68.1. Tunnel Interface is utun3. 
+
+When I run the command
+sudo networksetup -setadditionalroutes "VPN Work" 192.168.2.108 255.255.255.0 192.168.68.1
+my browser traffic goes through the VPN instead of my home network.
+What am I doing wrong?

+
+I run a bittorent server for openSource Linux distros. Over time I have manually blocked literally thousands of leachers and downloaders who I do not want to have access my system, as well as blocking 10s of 1,000s of botnets by firewalls. I have migrated my firewall settings to static routes blocked and the performance is much better. 
+
+I'm just having trouble consistently adding ip6 addresses to be blocked. 
+
+Beforehand, I enter the thousands of addresses I have collected to be blocked into JSON array lookup tables, to be accessed by a python script that reads them and inserts them into an iterating command line by nested for-loops.
+
+I always debug by entering the command first on a command line before automating the process.
+
+Example:
+
+I have been trying to set a permanent static route on my Mac using:
+networksetup -setadditionalroutes "Ethernet" 2408:8266:: ffff:ffff:fffc:0000:0000:0000:0000:0000 ::1
+   which returns:
+Route destination 2408:8266:: is not a valid IP address. ** Error: The parameters were not valid. ≈≈≈ That is not true as it is the top address of the CHINA UNICOM China169 Backbone server, from which I get scores of leachers and people who try to get past my firewall.
+
+   as well as trying:
+ifconfig en0 inet6 2408:8266:: prefixlen 32 alias
+  which blocks everything in 2408:8266::/32 except 2408:8266:: itself.
+
+My question is a) can networksetup -setadditionalroutes accept ip6 addresses and how?
+b) if not, can ifconfig block the root address of 2408:8266::/32?
+
+I would prefer a network setup solution because they much easier to clear than ifconfig ones.  Removing ifconfig entries can take hours, one and a time whereas networksetup just clears the service by name (Ethernet, WiFi, VPN) in moments
+
+On a parallel theme, is there away to wipe all the static route entries from my Mac, especially those put in by ifconfig in one fell swoop so I can re-enter them cleanly?
+
+Help is much appreciated.

+# Interpréter la sortie de smartctl
+
+## Instructions données par ChatGPT
+
+L’attribut Raw_Read_Error_Rate est souvent source de confusion, car il est interprété différemment selon le constructeur du disque. Voyons ça en détail :
+
+⸻
+
+1. Structure de la ligne
+
+ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE
+  1 Raw_Read_Error_Rate     0x000f   082   064   044    Pre-fail  Always       -       169987968
+
+	•	ID# 1 → C’est l’attribut S.M.A.R.T. standardisé pour les erreurs de lecture.
+	•	VALUE (82) → Valeur “normalisée” entre 1 et 100/200, fournie par le fabricant. Plus haut = meilleur.
+	•	WORST (64) → La plus mauvaise valeur atteinte dans l’historique.
+	•	THRESH (44) → Seuil en dessous duquel le disque est considéré en panne imminente.
+	•	TYPE Pre-fail → Signifie que si l’attribut franchit le seuil, le disque est considéré comme risqué pour la fiabilité.
+	•	RAW_VALUE (169987968) → Compteur brut. Son interprétation dépend du constructeur (Seagate, WD, Toshiba, etc.).
+
+⸻
+
+2. Interprétation
+	•	Ici, la valeur actuelle est 82, le pire atteint est 64, et le seuil critique est 44.
+👉 Comme 82 > 44, le disque n’a pas franchi la limite de sécurité fixée par le fabricant.
+	•	Le RAW_VALUE (169987968) n’est pas un nombre “d’erreurs brutes” simples :
+	•	Chez Seagate, ce nombre est souvent un compteur interne de tentatives et de corrections, pas directement une erreur fatale. Même un disque neuf peut avoir des valeurs RAW très élevées.
+	•	Chez Western Digital, cet attribut est parfois inutilisé ou toujours fixé à zéro.
+
+En résumé, il ne faut pas interpréter le RAW_VALUE comme “170 millions d’erreurs”, mais comme une donnée interne dont l’échelle est spécifique au firmware.
+
+⸻
+
+3. Comment savoir si c’est inquiétant ?
+	•	Ce qui compte réellement, c’est que la VALUE (82) reste au-dessus du THRESH (44).
+	•	Si vous voyez la valeur baisser régulièrement au fil des semaines/mois, le disque peut être en dégradation.
+	•	À court terme, avec 82 vs 44, le disque est encore jugé sain.
+
+⸻
+
+4. Vérifications complémentaires utiles
+	•	Regarder aussi les attributs :
+	•	5 Reallocated_Sector_Ct (secteurs réalloués)
+	•	197 Current_Pending_Sector (secteurs instables en attente)
+	•	198 Offline_Uncorrectable (secteurs non corrigibles)
+
+👉 Ce sont eux qui sont les indicateurs les plus fiables d’un disque en train de faillir.
+
+⸻
+
+✅ Interprétation pour votre cas :
+Votre disque est considéré sain du point de vue du constructeur : Raw_Read_Error_Rate est dans une plage normale, et la valeur est au-dessus du seuil critique. Le chiffre brut impressionnant est normal, surtout sur des disques Seagate.
+
+⸻
+
+Voulez-vous que je vous donne un petit script (en Bash ou Python) qui surveille automatiquement les attributs critiques S.M.A.R.T. (5, 197, 198) et vous alerte si ça se dégrade ?

+% Configuration de deux disques avec LVM
+
+:::information
+
+Sur ce schéma de partitionnement, on ne privilégie pas la fiabilité ou la redondance mais l'espace disque.
+
+Ici, ce serveur (de secours) est configuré pour être en *backup* d'un autre serveur (principal): si le serveur principal plante, le serveur de secours prend le relais.
+
+La sauvegarde des données n'est donc pas ici assurée: elle doit l'être par un autre moyen, en mettant une politique de sauvegarde réfléchie.
+
+:::
+
+# Schéma de partitionnement
+
+:::warning
+
+Tuto à refaire: on va partir en RAID0 car plus simple pour un déchiffrement en une fois du système.
+
+:::
+
+
+## Partition de boot
+
+On crée une partition de boot uniquement sur le premier disque: 512 Mo
+
+## *Swap*
+
+On crée deux partitions (une sur chaque disque) de 11,6 Go.
+
+## Données
+
+Le reste des disques sera affecté aux données.
+
+# Partitionnement
+
+## Vérification de la présence d'UEFI
+
+:::warning
+
+Bien vérifier si vous avez un système UEFI:
+
+```bash
+ls /sys/firmware/efi
+```
+
+
+**Si ce fichier n'existe pas, il faut utiliser une table MBR**
+
+Source: [Check if Computer Uses UEFI or Legacy BIOS [Linux & Windows]](https://itsfoss.com/check-uefi-or-bios/)
+
+:::
+
+Dans le cas contraire: il faut utiliser une table de partition MBR.
+
+## Partitionnement du premier disque
+
+```bash
+fdisk /dev/sda
+```
+
+### Création de la partition de boot
+
+Utilisation de la commande `n`
+
+```
+Command (m for help): n
+```
+
+Ensuite, on crée la partition numéro `1`
+
+```
+Partition number (1-128, default 1): 1
+```
+
+On laisse la valeur par défaut pour le premier secteur en appuyant sur `Entrée`
+
+```
+First sector (2048-3907029134, default 2048): 
+```
+
+Puis on indique la taille `+512M`:
+
+```
+Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-3907029134, default 3907028991): +512M
+```
+
+Le message suivant indique que la première partition est bien créée:
+
+```
+Created a new partition 1 of type 'Linux filesystem' and of size 512 MiB.
+```
+
+
+
+### Création de la partition de Swap
+
+À nouveau, on utilise la commande `n`, mais cette fois on choisit une taille en secteurs (qui correspond ici à 11,5Go):
+
+```
+Command (m for help): n [ENTREE]
+Partition number (2-128, default 2): [ENTREE]
+First sector (1050624-3907029134, default 1050624): [ENTREE]
+Last sector, +/-sectors or +/-size{K,M,G,T,P} (1050624-3907029134, default 3907028991): +24117248 [ENTREE]
+```
+
+Le message de confirmation permet de vérifier la taille:
+
+```
+Created a new partition 2 of type 'Linux filesystem' and of size 11.5 GiB.
+```
+
+On modifie ensuite le type de partition pour la `2` avec la commande `t`:
+
+
+```
+Command (m for help): t
+Partition number (1,2, default 2): 2
+Partition type or alias (type L to list all): 19
+```
+
+
+### Création de la partition principale
+
+Ici, on appuie sur `Entrée` pour laisser les valeurs par défaut:
+
+```
+Command (m for help): n
+Partition number (3-128, default 3): 
+First sector (25167873-3907029134, default 25169920): 
+Last sector, +/-sectors or +/-size{K,M,G,T,P} (25169920-3907029134, default 3907028991): 
+
+Created a new partition 3 of type 'Linux filesystem' and of size 1.8 TiB.
+```
+
+Et on modifie le type de la partition pour la passer en `Linux LVM`:
+
+```
+Command (m for help): t
+Partition number (1-3, default 3): 
+Partition type or alias (type L to list all): 43
+
+Changed type of partition 'Linux LVM' to 'Linux LVM'.
+```
+
+On termine par la commande `w` pour sauvegarder les changements de la nouvelle table des partitions:
+
+```
+Command (m for help): w
+The partition table has been altered.
+Calling ioctl() to re-read partition table.
+Syncing disks.
+```
+
+
+## Partitionnement du second disque
+
+Cette fois, on ne crée que deux partitions:
+
+- une Swap de `+24117248` secteurs
+- une principale sur le reste du disque
+
+```bash

+# Installation sur eMMC

+On grave sur une carte SD une image correspondant à `Rock Pi 4B plus`
+
+On boote dessus
+
+On flash l'eMMC en utilisant [ce tutoriel](https://wiki.radxa.com/Rockpi4/install/eMMC):
+
+:::information
+
+If you have no eMMC to μSD card converter board or you have ROCK 4A Plus or 4B Plus,
+
+    Install Debian Linux (or another Linux variant) first to microSD card following the microSD card installation page.
+    Insert both your microSD
+    Insert the (empty) eMMC module into the ROCK 4A, 4B, 4C, 4 SE, 4C Plus, for 4A Plus, 4B Plus, you have eMMC on the board already
+    Reboot it. It will boot from microSD
+
+You can now use that Linux on ROCK 4 to download your desired OS from Rockpi4/downloads and install it onto the eMMC module. Example:
+
+Verify that the system has booted from μSD, which should be /dev/mmcblk0p5 and that the eMMC module is found as /dev/mmcblk1:
+
+```bash
+$ dmesg | grep mmcblk
+...
+[...] EXT4-fs (mmcblk0p5): mounted filesystem with ordered data mode.
+
+$ ls -l /dev/mmcblk1
+brw-rw---- 1 root disk 179, 0 Jan  6 13:25 /dev/mmcblk1
+```
+
+Then write your downloaded OS image to eMMC:
+
+```bash
+$ sudo dd if=rockpi4_debian_stretch_lxde_armhf_20181105_2120-gpt.img of=/dev/mmcblk1 bs=1M
+```
+
+If you image downloaded is img.xz format, it's compressed, use
+
+```bash
+$ xzcat rockpi-4cplus-ubuntu-focal-server-arm64-20220520-1242-gpt.img.xz | sudo dd of=/dev/mmcblk1 bs=1M
+```
+
+A CLI tool to write an image with write diagnostics is pv:
+
+
+```bash
+$ sudo apt install pv
+$ sudo pv -ptera < rockpi4_debian_stretch_lxde_armhf_20181105_2120-gpt.img | dd of=/dev/mmcblk1 bs=1M
+```
+
+Power off your ROCK 4, remove the μSD and power on again. The system will now boot from the on board eMMC or eMMC module.

+# How to Share Host Folder with Guest VM in Proxmox Using Virtiofs
+
+<!-- image -->
+
+This guide explains how to access a shared folder on the host from a guest VM in Proxmox VE.
+
+– Make sure virtiofsd is installed on the Proxmox host
+
+```
+apt install virtiofsd
+```
+
+– Create a shared directory on the Proxmox host.
+
+```
+mkdir -p /srv/sharefolder/vm101
+```
+
+– Go to Proxmox GUI, select Datacenter | Directory Mappings. Click add. Adjust Name, Node, and the Path
+
+![](images/pve-directory-mapping-1024x394.webp)
+
+– Select VM who will access the folder share. Select Hardware | Add | Virtiofs
+
+![](images/add-virtiofs-vm.webp)
+
+![](images/select-virtiofs-vm.webp)
+
+– Start VM after added Virtiofs
+
+If your VM is running, you can shut it down and start it again.
+
+– Mounting folder share from VM
+
+Mount virtiofs
+
+```
+mount -t virtiofs vm101 /mnt/
+```
+
+To make the mounting permanent and automatic at boot, add it to the fstab. The content is as follows:
+
+```
+vm101 /mnt virtiofs rw,relatime 0 0
+```
+
+Good Luck 🙂
