[IUG] Re: FTP Servers and III

To build on this old post of yours Robert.

Has anyone else seen this behavior after upgrading to release 2005?

When trying to import a list of barcodes in INNOPAC via.
C > CIRCULATION subsystem
A > ADDITIONAL circulation functions
P > PROCESS PC transactions
F > IFTS Transfer of B321 or PC-CIRC transactions from PC

The Millennium software sends the command "NLST -l" to our ftp server 
(proftp).  This command does not make sense because the only thing that 
NLST is supposed to return is a basic list of filenames.  The ftp RFC 
says. " The data returned by an NLST command MUST contain only a simple 
list of legal pathnames, such that the server can use them directly as 
the arguments of subsequent data transfer commands for the individual 
files." 
http://www.freesoft.org/CIE/RFC/1123/53.htm
Innovative seems to be trying to get a long list of the files, one with 
sizes and ownership etc.  proftp correctly returns a simple list of just 
the filenames which the FTS software cannot handle so it displays nothing. 

Can anyone confirm that with a pre 2005 system the FTS software sends a 
"LIST -l" command?  This just reared it's head after we upgraded to 2005 
last fri.
Thanks
