Je pense à un problème sécurité. Y a t'il quelque chose comme apparmor sur le poste ?

Essayes avec la commande system plutôt qu'exec pour voir si ça change quelque chose.

Mais tu ferais mieux de passer par cron hors php.

Bonjour,

Je pense à un problème sécurité. Y a t'il quelque chose comme apparmor sur le poste ?

non

Essayes avec la commande system plutôt qu'exec pour voir si ça change quelque chose.

idem

Mais tu ferais mieux de passer par cron hors php.

non car c'est une application php qui utilise dirvish mais j'ai fait un petit fichier php qui concentre le pb voir post précédent lien sur ...;

Merci quand même

Je ne sais pas quoi faire ?

Personne connait les appels capget ... Qu'est qui différencie Debian 9 et 8 sur ces appels ? Il s'agit simplement de lancer en www-data un sudo mount dans un fichier php !

**chrtophe** · 28/06/2019, 09h34

Extrait de la doc de la fonction capget :

Depuis Linux 2.2, la toute puissance du superutilisateur (root) a été scindée en plusieurs ensembles distincts. Chaque thread dispose d'un ensemble de capacités effectives permettant d'identifier ses droits de réaliser certaines actions. Chaque thread a aussi un ensemble de capacités héritables, qu'il peut transmettre au travers d'un execve(2) et un ensemble de capacités éventuelles qu'il peut rendre effectives ou héritables.
Ces deux fonctions constituent l'interface brute du noyau pour configurer ou lire les capacités d'un processus. Non seulement ces appels système sont spécifiques à Linux, mais l'API du noyau est susceptible de changer. L'utilisation de ces fonctions (en particulier le format du type cap_user_*_t) risque de varier lors de nouvelles mises à jour du noyau.

merci quand même mais j'ai plus d'information. Désolé

mais ça marche sur debian 8 :
Linux kvm-backup-sgp 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2+deb8u3 (2017-08-15) x86_64 GNU/Linux

pas sur Debian 9 :

Une idée ?

Il s'agit ici de montrer le cas bloquant, mais en fait c'est une application de type dirvish qui plante de la même manière via l'appel php

J'ai essayé : sudo capsh --print voir les capabilities getpcaps 1234 (numéro de process) mais ça ne n'avance pas plus !

**N_BaH** · 15/12/2020, 17h25

tu peux essayer sur une autre distribution non basée sur Debian ?
pour voir si le problème vient de la distro ou du passage d'une version de PHP à une autre.

**falco-** · 02/03/2021, 14h31

Bonjour,
je n'ai pas pu tester sur un autre système ou sur une autre version php !

j'aimerais savoir comment vous faites pour monter une ressource (il faut que je le fasse de cette façon !) via une page php ?

Merci

Voir :getcap /bin/mount
setcap cap_net_raw=pe  /bin/mount (ici ajoute effective et permit)
getcap /bin/mount donne
/bin/mount = cap_net_raw+ep

J'ai relancé le go.php ---> idem pas de montage via la commande mount !!!

Si un spécialise linux peut m'aider ?
Merci
