The following is an overview of new features available with FTP/iX.
Implementation of FTPSRVR under INETD
Until now, FTP/iX server service, FTPSRVR, was initiated by the FTPMON process
which was started by the JFTPSTRT.ARPA.SYS job. The INETD/iX process
will now replace the FTPMON process and the JFTPSTRT.ARPA.SYS job
will be replaced by JINETD.NET.SYS job.
Anonymous FTP Functionality
FTP/iX anonymous logon allows a restricted access to the MPE/iX file system
via the FTP/iX server, without the need for a logon account. The remote user
can access the FTP/iX anonymous environment by specifying either one of the
accepted user names 'anonymous' or 'ftp' (these login id's are currently
defacto standards).
Support for Non-Standard MPE/iX File Types
The following types of MPE/iX files can be transferred to a remote host using
FTP.
- Standard MPE files with fixed, variable or bytestream format.
- Files with either binary or ASCII data types.
The Configurable Server Time-Out
Previous patch releases of FTP/iX 5.0 and 5.5 have a hard-coded infinite
time-out value applied to the data connection timer of the FTP/iX server. The
FTP/iX client, which shares this data connection, has a configurable time-out
which is user-controlled through the TIMEOUT command.
Hash Command
While transferring files, if the user desires to receive progress status
during file transmission, the hash command provides this capability.
REPLACE Command
This FTP/iX client controlled option allows the user to override the default
file placement strategy of FTP/iX (unconditional replacement of the target
file.)
MOVE Option
This FTP/iX user-controller option allows the user to selectively specify on
the GET, PUT, MGET, or MPUT command whether to delete the
source file after confirmation of a successful file transfer to the target
system.
Details and example of these options for FTP/iX are provided in the "Technical
Articles" chapter of this book.
The Implementation of CI Environment Variables for Additional FTP/iX
Status Information
The following status information will be provided through these CI environment
variables:
- FTPXFERFILES
- number of files successfully transferred during the last FTP/iX
execution.
- FTPREQFILES
- total number of files requested for transfer during the last FTP/iX
execution.
- FTPREPLACE
- reflects the state of the file placement policy of FTP/iX: either
unconditionally (TRUE) or conditionally (FALSE) replace the target
file(s) specified in the user commands GET, PUT, MPUT, and MGET (see the
REPLACE option for additional details).
The following environment variables are currently supplied with FTP/iX:
- FTPLASTERR
- identifies the last FTP error encountered.
- FTPLASTREPLY
- identifies the last FTP protocol reply message string.
