On listing files from the esa ftp server: eg

ftp://anonymous@ftp.esrin.esa.it/pub/RA2_MWR/USO/auxdata/cycle_47

(and other directories at this level) some of the filenames are erroneaously reported as having underscores replacing the characters that should be there.

Eg. shawing partial listings:
Cyberduck (from log drawer) reports:

 -rw-rw-r--   1 descw    eoa         38280 Apr 13  2007 RA2_USO_CLOCK_O_20060522_140220_000049692047_00497_22094.gz
 -rw-rw-r--   1 descw    eoa          5835 Apr 13  2007 RA__USO_CLOCK_O_20060522_152917_000007012047_00498_22095.gz
 -rw-rw-r--   1 descw    eoa         45011 Apr 13  2007 RA2_USO_CLOCK_O_20060522_154026_000058652047_00498_22095.gz

whilst from the command line (for the same 3 files) I get:

-rw-rw-r--   1 descw    eoa         38280 Apr 13  2007 RA2_USO_CLOCK_O_20060522_140220_000049692047_00497_22094.gz
-rw-rw-r--   1 descw    eoa          5835 Apr 13  2007 RA2_USO_CLOCK_O_20060522_152917_000007012047_00498_22095.gz
-rw-rw-r--   1 descw    eoa         45011 Apr 13  2007 RA2_USO_CLOCK_O_20060522_154026_000058652047_00498_22095.gz

ie the second file has the first "2" replaced with "_".

Trying to download the file which has the erroneous filename from cyberduck fails with "file not found" error - not surprising as the name is wrong. Using get from the command line, using the correct filename, works fine.

Refreshing the list will change the filenames reported - with different files having "2" replaced with "_".
Occasionally, it is the second "2" in the filenames that is replaced, eg RA2_USO_CLOCK_O_2006.... becomes RA2_USO_CLOCK_O__006...

The directories concerned each contain more than 500 files

I cannot replicate the problem. The file RA2_USO_CLOCK_O_20060522_152917_000007012047_00498_22095 is listed correctly here. If already the transcript shows the wrong name, that is either a bug in the server occasionally returning a faulty name or a network component in between that filters the traffic and introduces the error. I don't think there is much I can about here. If you don't think so or have more information, please reopen the ticket.
