By NDM, i take it, you mean Connect:Direct? Connect:Direct is a file transfer solution for the host, because ftp (the protocol as well as the program) is part of (the) TCP/IP (stack). The hosts native network stack is SNA (or, more precisely "a SNA-based protocol stack"), though. Ones uses LU2-connections to transfer data in this environment.

So, you first need to determine if your hosts still talks over SNA to others. You need some complex machinery including a 3745 frontend-processor and a 3174-compatible cluster controller or a virtualised replacement for the latter (SNA gateway software usually acts as a 3174 with its own NCP to the host) to do so. Many companies have therefore cut their SNA networks and work exclusively over TCP/IP.

If your host uses TCP/IP you should stay away from FTP at all costs: use scp or (preferably) rsync which is both available for z/OS. These tools will save you perhaps days and weeks of shell-programming efforts because whatever you can come up with they do: out of the box and perhaps better.

I hope this helps.

VANESSA_SOCKET_PIPE(1)					      General Commands Manual					    VANESSA_SOCKET_PIPE(1)

NAME

       vanessa_socket_pipe - Trivial TCP/IP pipe based on libvanessa_socket

SYNOPSIS

       vanessa_socket_pipe [options]

DESCRIPTION

       A  TCP/IP  pipe	is a user space programme that listens for TCP/IP connections on port on the local host and when a client connects makes a
       connection to a TCP port, possibly on another host. Once both connections are established data sent on one connection  is  relayed  to  the
       other, hence forming a bi-directional pipe.

       Uses include enabling connections to specific ports on hosts behind a packet filter.

       This code is intended primarily as an example of how many of the features of libvanessa_socket work.

OPTIONS

       -c|--connection_limit:
	      Maximum  number  of  connections	to accept simultaneously. A value of zero sets no limit on the number of simultaneous connections.
	      (default 0)

       -d|--debug:
	      Turn on verbose debuging to stderr.

       -h|--help:
	      Display this message.

       -L|--listen_port:
	      Port to listen on. (mandatory)

       -l|--listen_host:
	      Address to listen on. May be a hostname or an IP address.  If not defined then listen on all local addresses.

       -n|--no_lookup:
	      Turn off lookup of hostnames and portnames. That is, hosts must be given as IP addresses and ports must be given as numbers.

       -O|--outgoing_port:
	      Define a port to connect to. If not specified -l|--listen_port will be used.

       -o|--outgoing_host:
	      Define host to connect to.  May be a hostname or an IP address. (mandatory)

       -q|--quiet:
	      Only log errors. Overriden by -d|--debug.

       -t|--timeout:
	      Idle timeout in seconds.	Value of zero sets infinite timeout.  (default 1800)

       Notes: Default value for binary flags is off.
	      -L|--listen_port and -o|--outgoing_host must be defined.
