[BlueOnyx:07468] Proftpd 1.3.3e: LIST -R broken after latest Updates

[free4me at gmx.ch]

Hi All

Hi All

A customer has notified me that he can not anymore use "LIST -R" native FTP Command on my ftp server (centos 5.5, Proftp 1.3.3e) . The problem happens after the Proftp Update to the 1.3.3e Version. The configuration file itselve did not change.

The customer has send me two output logs:

So depending on ftp client he get different "error" returns.


In the attached text file is part of the trace log, but i'm unable to interpret it properly (Trace Debug Level 10)

Any help? As mention before: the configuration file is exactly the same as it was prior the update. Nothing has changed in the configuration itselve and the problem occurs exactly after the 1.3.3e Update.

Best Regards
