[fixed] Unable to connect behind Squid Proxy since FileZilla Client 3.25.x

#1 Post by xhark » 2017-03-20 20:42

Hi guys

We use a squid proxy FTP on specific port (olfeo security appliance based on 3.1.19-1). HTTP proxy is on another port (8080) and FTP is on 9021.
Proxy IP is 192.168.22.152.

Proxy is configure with "FTP proxy" on "USER@HOST" and theproxy:9021 (no auth).

Up to FileZilla Client 3.24.1 it works fine :

Code: Select all

Statut :	Connexion à ftpperso.free.fr via FTP Proxy
Statut :	Connexion à 192.168.22.152:9021...
Statut :	Connexion établie, attente du message d'accueil...
Statut :	Le serveur ne supporte pas les caractères non-ASCII.
Statut :	Connecté
Statut :	Récupération du contenu du dossier...
Statut :	Contenu du dossier "/" affiché avec succès
Since FileZilla Client 3.25.x the connection does not work :

Code: Select all

Statut :	Connexion à ftpperso.free.fr via FTP Proxy
Statut :	Connexion à 192.168.22.152:9021...
Statut :	Connexion établie, attente du message d'accueil...
Statut :	Le serveur ne supporte pas les caractères non-ASCII.
Statut :	Connecté
Statut :	Récupération du contenu du dossier...
Commande :	PWD
Réponse :	500 PWD not understood
Erreur :	Impossible de récupérer le contenu du dossier
Does anyone know why I get the 500 PWD not understood error?

I have never seen this error before 3.25.x. When I do a downgrade to 3.24.x it works again.

OS: Windows 7 Pro SP1 64bits (AV disabled)
Thank you for your support

That's a strange error. Using the old version, could you please right-click the message log, select "Show detailed log" and then connect to the server and post the results here?

This issue has already been fixed in the repository. Until 3.25.2 or later gets release, please use this build of FileZilla in the meantime:
