I think it depends on your understanding of the RFC (rfc959)
According to the RFC
Quote:
To solve these problems, upon successful completion of an MKD command, the server should return a line of the form:
257<space>"<directory-name>"<space><commentary>
For example, a user connects to the directory /usr/dm, and creates
a subdirectory, named pathname:
CWD /usr/dm
200 directory changed to /usr/dm
MKD pathname
257 "/usr/dm/pathname" directory created
|
However ioFTPD doesn't return the absolute pathname in the 257 reply, If the directory is created relative to the folder only the folder name is returned. Steps have been taken to address this issue so whether ioFTPD changes it's behavior or not really doesn't matter.
