504: command STOU not supported for named pipes

Explanation

The FTP server received a STOU (store-unique) command that specified a named pipe. The command is not supported for named pipes.

The UNIXFILETYPE configuration option at the FTP server determines whether the STOU command argument is a named pipe or a regular z/OS® UNIX file. See the UNIXFILETYPE (FTP client and server) statement in z/OS Communications Server: IP Configuration Reference for more information about the UNIXFILETYPE configuration option.

See the information about using z/OS UNIX System Services named pipes in z/OS Communications Server: IP User's Guide and Commands for information about transferring data to named pipes..

Example

Command:                                         
put /etc/hosts /tmp/my.fifo                      
>>> PORT 9,2,1,3,4,44                        
200 Port request OK.                             
>>> STOU /tmp/my.fifo

Do one of the following actions:

Append to the named pipe instead of storing into the named pipe.
Configure your FTP client to send the STOR command instead of the STOU command to the server, and send the file or data set again. See the SUnique subcommand in z/OS Communications Server: IP User's Guide and Commands for information about configuring the z/OS FTP client to send the STOR command instead of the STOU command.
