Doc Text:
When the "case" command was used to turn on the remote computer file name case mapping, using the "mget" command to download remote files may have caused the ftp client to overwrite the files on the client machine with the wrong content, or fail when mixed-case file names were used. For example, downloading multiple files may have resulted in a single file, that contained the content of a different file. This has been fixed, and all files are now transferred with their original content as expected.

Description Jeff Bastian 2008-04-16 17:38:16 UTC 
+++ This bug was initially created as a clone of Bug #442710 +++

Description of problem: 
ftp can overwrite files with the wrong content or fail to get/put files when
mixed-case filenames are involved.

Version-Release number of selected component (if applicable):
ftp-0.17-23.EL4

How reproducible: 
always

Steps to Reproduce: 

1.  Login to a linux box and install/start up vsftpd.  
2.  Create the following files in /var/ftp/pub
  * Test1.out1
  * TEST2.OUT2
  * tesT3.Out3

3. Connect to ftp server

ftp> ls
227 Entering Passive Mode (9,67,58,187,198,5)
150 Here comes the directory listing.
-rw-rw-r--    1 503      503            11 Apr 11 15:33 TEST2.OUT2
-rw-rw-r--    1 503      503            11 Apr 11 15:32 Test1.out1
-rw-rw-r--    1 503      503            11 Apr 11 15:33 tesT3.Out3
226 Directory send OK.
ftp> bin
200 Switching to Binary mode.
ftp> prompt
Interactive mode off.
ftp> case
Case mapping on.
ftp> mget *
local: test2.out2 remote: TEST2.OUT2
227 Entering Passive Mode (9,67,58,187,161,53)
150 Opening BINARY mode data connection for TEST2.OUT2 (11 bytes).
226 File send OK.
11 bytes received in 0.0086 seconds (1.3 Kbytes/s)
local: test2.out2 remote: Test1.out1
227 Entering Passive Mode (9,67,58,187,23,178)
150 Opening BINARY mode data connection for Test1.out1 (11 bytes).
226 File send OK.
11 bytes received in 0.0037 seconds (2.9 Kbytes/s)
local: test2.out2 remote: tesT3.Out3
227 Entering Passive Mode (9,67,58,187,72,19)
150 Opening BINARY mode data connection for tesT3.Out3 (11 bytes).
226 File send OK.
11 bytes received in 0.006 seconds (1.8 Kbytes/s)


Actual results:  
local filename for the second 2nd and 3rd files transfered is the same as the
first.  The end result is a single file in the local directory called test2.out2
with the contents of tesT3.Out3

Expected results:  
3 files transfered with their original contents.  Only the file with all
uppercase in the name is translated to lowercase (according to the ftp manpage
at least.)
