Bonjour à tous! Depuis aujourd’hui, je constate un comportement étrange de ma commande su: Tout se passe bien jusqu’à l’entrée de mon mot de passe(erreur si le nom d’utilisateur ou le mot de passe est faux) mais ensuit, je n’ai plus de d’invit' de commande mais celles-ci sont tout de même lues et exécutées avec les bons droits (mais je n’ai aucunes des fonctions d’un shell normal comme l’auto-complétion). De plus e changement d’utilisateur deviens sensible à un envoie du sigint (ce qui ne semble pas être devoir être le cas). Enfin, ce comportement étrange ne s’observe que depuis mon utilisateur principal mais pas depuis root (je n’ai pas d’utilisateur secondaire pour tester) alors que j’ai vérifié que les deux lançaient /usr/bin/su.

Voici le strace de la commande:

depuis mon utilisateur principal:

Au niveau des environnements de variables ? Tu n’as rien de différents ? (Commande env).

J’utilise bash pour root comme pour l’utilisateur principal

Normalement, tu devrais avoir d’autres utilisateurs que root. dbus, nobody, …

ache

Depuis root, on me répond que l’utilisateur n’est pas disponible, depuis l’utilisateur principal, je me retrouve avec une demande de mot de passe.

Question bête, tu lances su tout court ou su - ?

Ah zut ! J’aurais du être plus claire >_<"

Il aurait fallu taper su -c env depuis les deux utilisateurs. Mais appart COLOR_RED= je ne vois rien de bizarre. Et franchement, ça ne me semble pas être la cause du problème.

Oui, c’est normal. Leur shell doit être /bin/nologin. Tu dois simplement, depuis root faire su dbus -s /usr/bin/bash

Pour COLOR_RED et COLOR_RESET, c’est juste pour la coloristaion de stderr, je ne sais pas pourquoi ces variables sont affichées vides.

Visiblement, le soucis ne vient que depuis l’utilisateur principal, depuis les utilisateurs dbus et nobody, il n’y a pas de soucis.

En utilisant la commande su -c env, le retour est le même que le retour de env (les deux étant exécutées depuis l’utilisateur principal), mais pas depuis root où j’ai pour su -c env paul:

SHELL=/bin/bash
PWD=/root

Salut,

Si je comprends bien, lorsque tu exécutes la commandes su alors que tu es l’utilisateur paul, tu n’as plus d’invite de commande une fois que tu deviens root. Autrement dit, tu peux effectivement entrer des commandes, mais tu n’as rien qui t’indique si une commande est attendue ou non, c’est bien ça ?

Si oui, ce qui est étrange, c’est que l’instance de bash exécutée par su semble se comporter comme si tu avais défini la variable d’environnement PS1 en lui assignant pour valeur une chaîne vide. Tu peux faire le test vite fait comme suit, tu obtiendras le même résultat qu’avec su.

$ PS1=''
# Allo ?
PS1='$ '
$

La question maintenant c’est de savoir pourquoi et là j’en sais rien.
En toute logique, si tu ne définis pas la variable PS1, bash utilise une valeur par défaut du type -bash-x.x#. Est-ce que tu peux me dire ce que tu obtiens avec la suite de commandes suivante ?

$ export PS1='(mon invite de commande) '
(mon invite de commande) su 
(mon invite de commande) # Cet invite reste-t-il une fois root ?
(mon invite de commande) exit
(mon invite de commande) su -l
# As-tu un invite de commande ?

Salut! J’ai fais es tests demandés, mais je n’ai aucun invite de commande dans tous les cas.

Mais j’ai fais un test en repensant que j’ai ajouté ça au .bashrc de ma séssion principale:

#stderr color
export COLOR_RED="$(tput setaf 160)"
export COLOR_RESET="$(tput sgr0)"

exec 9>&2
exec 8> >(
    perl -e '$|=1; while(sysread STDIN,$a,9999) {print
"$ENV{COLOR_RED}$a$ENV{COLOR_RESET}"}'
)
function undirect(){ exec 2>&9; }
function redirect(){ exec 2>&8; }
trap "redirect;" DEBUG
PROMPT_COMMAND='undirect;'

Dans le but de colorer stderr. En le commentant, su reprend son comportement normal…

Sais-tu ce qui pose problème dans ce morceau de code et comment continuer à colorer stderr sans perturber la commande?

Merci pour ton aide!

Malheureusement, je ne suis pas expert en bash et je ne comprends pas tous les tenants et aboutissants de ce script. ^^"

Je comprends qu’il crée deux descripteurs de fichiers (via exec 9>&2 et exec 8> >(...)) et qu’il tente ensuite de s’en servir pour rediriger et colorer la sortie d’erreur standard, d’une part via le signal DEBUG qui est envoyé avant chaque commande et, d’autre part, via la fonction PROMPT_COMMAND qui est évaluée avant chaque invite de commande, mais je m’y perds un peu…

Cela étant dit, l’absence de la création des descripteurs 8 et 9 dans le bashrc des autres utilisateurs est sûrement liée à ton problème.

Après BEAUCOUP de tests et de recherches, il semble que le souci soit la redirection qi est fait au lancement de la commande. j’ai donc essayé d’aliasser su avec une suite de commande avec un truc qui ferait un reset du trap et qui remettrait ça en place une foi le su terminé mais ça ne semble pas fonctionner: le reset du trap ne prends effet que après le retour de la commande. et je ne vois pas du tout pourquoi…

Visiblement, il existe une petit librairie bibliothèque nommée stderred qui peut être utilisée pour cela. Cela sera sans aucun doute plus efficace que n’importe quel bricolage en bash.
