Red Hat Bugzilla – Bug 58674
"ncftpls -1" can report bogus error
Last modified: 2007-04-18 12:39:08 EDT
With ncftp-3.1.1-1 and earlier versions as well:
> ncftpls -F -1 ftp://126.96.36.199/pub/linux/kernel/people/hedrick/ide-2.2.20/
ncftpls: directory listing error: could not start data transfer.
The problem goes away if you omit the "-1" flag.
The problem is that some FTP server implementors have decided that NLST should
return an error if a directory is empty, rather than returning a success code
and sending no data on the data socket. This is stupid, because it makes it
impossible for a client to distinguish reliably between a real error retrieving
a directory listing and merely an empty directory listing.
In any case, I will attach a patch to work around this stupid server behavior.
