Hello folks ^^)


bon, le passage de buster Í  bullseye sur serveur ne se fait pas sans
problèmes :(


dabort, mon proftpd ne voulait pas se mettre Í  jour : résolu en
désinstallant tout proftpd (plus rien ne faisant référence Í  lui sur le
serveur) puis install proftpd-basic qui appelle correctement les
dépendances.

un problème de moins ;

ensuite restauration des nouvelles confs et redémarrage du serveur ;

essaie de connexion ftps avec filezilla comme ça fonctionnait sous
buster : niet ! 'vous vous êtes déjÍ  connecté Í  ce serveur en ftp over
tls mais ce serveur ne supporte pas ftp over tls' ! un comble !


c'est quoi le problème maintenant ???

Bonjour Jean-Fransoué,
Je te conseille de monter d'un cran en n'employant plus
le ftp directement, voici le tutoriel qui te permettra
d'augmenter la sécurité :
https://www.digitalocean.com/community/tutorials/how-to-configure-proftpd-to-use-sftp-instead-of-ftp
et pour faire passer la pilule :
https://www.youtube.com/watch?vDFWZ03kWog
désolé, mais je ne vois que cette solution
Bonne chance pour la suite
Bien Í  toi

Salut,
Tu as regardé si le module mod_tls était activé dans
/etc/proftpd/modules.conf ?
Tu peux lister les modules avec :
$ proftpd --list
Tu peux aussi lancer proftpd en mode debug pour avoir plus d'informations :
$ proftpd --nodaemon --debug 10
Pour valider la syntaxe de la configuration :
$ proftpd --configtest

bon, le passage de buster Í  bullseye sur serveur ne se fait pas sans
problèmes :(
dabort, mon proftpd ne voulait pas se mettre Í  jour : résolu en
désinstallant tout proftpd (plus rien ne faisant référence Í  lui sur le
serveur) puis install proftpd-basic qui appelle correctement les
dépendances.
un problème de moins ;
ensuite restauration des nouvelles confs et redémarrage du serveur ;
essaie de connexion ftps avec filezilla comme ça fonctionnait sous
buster : niet ! 'vous vous êtes déjÍ  connecté Í  ce serveur en ftp over

zieuté et effectivement la conf Í  changé entre les deux versions et

donc activé et lÍ  ça remarche comme sous buster !
ouais !
je n'avais pas pensé Í  ça vu que ça fonctionnait tout seul avant. Merci
de m'y avoir fait penser ^^)
Tu peux lister les modules avec :
$ proftpd --list

effectivement il n'y était pas listé et c'est toujours le cas puisque
cette commande liste uniquement les modules qui sont compilés intégrés
dans le programme ;)
Tu peux aussi lancer proftpd en mode debug pour avoir plus
d'informations :
$ proftpd --nodaemon --debug 10
Pour valider la syntaxe de la configuration :
$ proftpd --configtest
