This makes no sense.

1. The Server FTPD specifies ANONYMOUSLEVEL 1
2. I have no idea what the client FTPD specifies, but ANONYMOUSLEVEL is a
server-only configuration statement.
3. There should be no "anonymous" anywhere in this picture. The first
statement in the INPUT data set is USER userid password

It appears to me that the error occurs very early on the initial connection
because there is no 220-FTPD1 IBM FTP CS V2R4 at ... as would be expected.

No TLS in the picture, and we're not up to that point in the dialog anyway.

I duplicate the customer's parameters as closely as I can (different naming
conventions and so forth, of course) and it works exactly as expected.

Has anyone seen this? Does anyone have any idea what might be going on?

Subject: FTP Switch between users not accepted as anonymouslevel = 3

Does anyone know what the heck I should be looking for on this?

 

A customer running the z/OS FTP client is attempting to log into our FTP
server. The FTP client is ATTACHed dynamically with FTP -e -i -n
-f//DD:SYS00032 url.of.ftp.server

 

The FTP client is passed an INPUT file that begins

 

User    userid  password

 

The output from the FTP client is

 

EZA1736I FTP -e -i -n -f //DD:SYS00032 url.of.ftp.server

EZY2640I Using dd:SYS00032 for local site configuration parameters.

EZA1450I IBM FTP CS V2R3

EZA1772I FTP: EXIT has been set.

EZA1554I Connecting to: url.of.ftp.server dotted.address port: 21.

EZA2589E Connection to server interrupted or timed out. USER command failed.
Switch between users not accepted as anonymouslevel = 3

EZA1735I Std Return Code = 10000, Error Code = 00008

 

I can connect from another z/OS system using similar parameters with no
problem, but this customer has never tried it before. "Nothing has changed."
Does anyone have a clue?
