One last thing before you put a perimeter machine on the network. You could also build a Win2KPro machine (or even a Linux or FreeBSD machine) that is locked down and runs an FTP server. Then have a CMD script or anything equally automated to SFTP the data from that host to the SFTP server behind your ISA server. Then you stay as secure as possible and all you have to do on the ISA machine is server publish a single host/port. You could give these "sender computers" away or just charge what they are worth. I guess the whole expense would be time. Also, SFTP has been around for a long time (10+ years?), so I would not discount the availability of SFTP clients for MVS. I am sure one exists for Open/VMS. Just some thoughts, at the expense of your time. :) --orig >Good thought, but we have business partners with MVS (IBM 390), VMS, and a >slew of other old architectures. >And these folks are our customers and/or our customers' customers, we are >not in a business position to dictate to them. > >Putting a dedicated machine on the perimeter looks like the route we will >have to go.
