Python ftplib problems
 

I'm using python ftplib to automate uploading some files to a webhost, but it's haveing some really strange problems. Here's an example log with debuglevel set to 2:

>>> ftp.retrlines("LIST")
*cmd* 'TYPE A'
*put* 'TYPE A\r\n'
*get* '200 TYPE is now ASCII\r\n'
*resp* '200 TYPE is now ASCII'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (67,18,107,164,165,162)\r\n'
*resp* '227 Entering Passive Mode (67,18,107,164,165,162)'
*cmd* 'LIST'
*put* 'LIST\r\n'
*get* '150 Accepted data connection\r\n'
*resp* '150 Accepted data connection'

*get* '226-Options: -l \r\n'
*get* '226 6 matches total\r\n'
*resp* '226-Options: -l \n226 6 matches total'
'226-Options: -l \n226 6 matches total'
>>> ftp.cwd('www')
*cmd* 'CWD www'
*put* 'CWD www\r\n'
*get* '250 OK. Current directory is /www\r\n'
*resp* '250 OK. Current directory is /www'
'250 OK. Current directory is /www'
>>> ftp.retrlines('list')
*cmd* 'TYPE A'
*put* 'TYPE A\r\n'
*get* '200 TYPE is now ASCII\r\n'
*resp* '200 TYPE is now ASCII'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (67,18,107,164,88,86)\r\n'
*resp* '227 Entering Passive Mode (67,18,107,164,88,86)'

The transfer then times out. This has happened every single time i try to connect, where it will list the files in the root dir, but time out on any other kind of transfer. I'm behind a FW, could that have something to do with it? The server is running PureFTPd 1.0.12.
