I modified the program by adding line: ftp.set_debuglevel(2)
START LISTING----------------
import ftplib

ftp = ftplib.FTP('ftp.edgecastcdn.net', user='myuserid',
passwd='mypassword')
ftp.set_debuglevel(2)
ftp.cwd('chrismahan-675')
ftp.dir()
#ftp.retrlines('LIST')
ftp.close()
END LISTING ---------------

Running from idle 1.2.4 with python 2.5.4 gives this output:

*cmd* 'CWD chrismahan-675'
*put* 'CWD chrismahan-675\r\n'
*get* '250 CWD command successful\r\n'
*resp* '250 CWD command successful'
*cmd* 'TYPE A'
*put* 'TYPE A\r\n'
*get* '200 Type set to A\r\n'
*resp* '200 Type set to A'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (72,21,82,190,234,6).\r\n'
*resp* '227 Entering Passive Mode (72,21,82,190,234,6).'

*get* '226 Transfer complete\r\n'
*resp* '226 Transfer complete'


Then running with idle 3.0 with python 3.0 gives the following result.

*cmd* 'CWD chrismahan-675'
*put* 'CWD chrismahan-675\r\n'
*get* '250 CWD command successful\n'
*resp* '250 CWD command successful'

*put* 'TYPE A\r\n'
*get* '200 Type set to A\n'
*resp* '200 Type set to A'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering Passive Mode (72,21,82,190,148,178).\n'
*resp* '227 Entering Passive Mode (72,21,82,190,148,178).'
*cmd* 'LIST'
*put* 'LIST\r\n'
*get* '150 Opening ASCII mode data connection for file list\n'
*resp* '150 Opening ASCII mode data connection for file list'

Note that the last two lines are missing.
