Hi, thanks for tanking care of this issue.
I am mainly working on a windows client and connect to a z/OS host.
Attached you find the ftplib.py I patched to workaround this.
Here is the output of the list command which ends up in an exception (this time
from a unix machine, where I still have found the unpatched version of
ftplib.py):
>>> ftplib.FTP_TLS.debugging=True
>>> conn=ftplib.FTP_TLS(host=url, user=user, passwd=passw)
*resp* '220-TCPFT000 IBM FTP CS V2R2 at tcpip06, 11:38:07 on 2018-03-26.\n220
Connection will close if idle for more than 5 minutes.'
*cmd* 'AUTH TLS'
*resp* '234 Security environment established - ready for negotiation'
*cmd* 'USER SBxxxxx'
*resp* '331 Send password please.'
*cmd* 'PASS ********'
*resp* '230 SBxxxxx is logged on. Working directory is "SBxxxxx.".'
>>> conn.prot_p()
*cmd* 'PBSZ 0'
*resp* '200 Protection buffer size accepted'
*cmd* 'PROT P'
*resp* '200 Data connection protection set to private'
'200 Data connection protection set to private'
>>> conn.retrlines("LIST 'SBxxxxx.SBxxxxx.*'")
*cmd* 'TYPE A'

*cmd* 'PASV'
*resp* '227 Entering Passive Mode (53,113,100,193,250,60)'
*cmd* "LIST 'SBxxxxx.SBxxxxx.*'"
*resp* '125 List started OK'
