I did the FTP front end on two nodes of my grid. One inside my home network, and the other on a public IP on a hosted machine. The FTP works on the internal network machine but not on the other one (setup differs also as the internal one is ubuntu and the external is debian, but both are missing the vfs ftp.py file). On the external one I get (sorry some of it is french):: Commande: LIST Réponse: 550 Requested action not taken: internal server error Erreur: Échec lors de la lecture du contenu du dossier Réponse: 503 Incorrect sequence of commands: must send PORT or PASV before RETR In the twisted log I get :: 2009-04-30 19:06:45+0200 [ProtocolWrapper,0,86.69.160.55] twisted.protocols.ftp.DTPFactory starting on 40749 2009-04-30 19:06:45+0200 [ProtocolWrapper,0,86.69.160.55] Starting factory 2009-04-30 19:06:45+0200 [-] (Port 44070 Closed) 2009-04-30 19:06:45+0200 [-] Stopping factory 2009-04-30 19:06:45+0200 [-] dtpFactory.stopFactory 2009-04-30 19:06:55+0200 [-] timed out waiting for DTP connection 2009-04-30 19:06:55+0200 [-] Unexpected FTP error 2009-04-30 19:06:55+0200 [-] Unhandled Error Traceback (most recent call last): Failure: twisted.internet.defer.TimeoutError: 2009-04-30 19:06:55+0200 [-] dtpFactory.stopFactory " defect closed major undecided unknown 1.4.1 invalid
