Hello folks ^^)


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


dabort, mon proftpd ne voulait pas se mettre à jour : résolu en désinstallant tout proftpd (plus rien ne faisant référence à 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 déjà connecté à 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?v=44FWZ03kWog

désolé, mais je ne vois que cette solution

Bonne chance pour la suite

Bien à toi

Bernard

heu ! j'employais le ftpS pas le ftp... et ça marchait. sécurisé par TLSv1.2.

Bonjour,

C'est un peu nul comme réponse mais la dernière fois que j'ai eu
un problème avec proftpd (il y a environ 15 ans), j'ai essayé
vsftpd qui m'a semblé beaucoup plus simple à administrer et à
maintenir. J'ai gardé un mauvais souvenir de proftpd (il fallait
que je remettes "les mains dans le cambouis" à chaque mise à
jour).

Cordialement
Hugues

avec ces confs, le ftp over tls fonctionnait parfaitement sous buster et

plus du tout sous bullseye...

les clés ssl sont à leur place donc qu'est-ce qui va plus ici ?

grrr!
