We are looking for a better explanation, or even a better method to manage these utilities. Too bad the books don't explain this well. The SE and the FTP server must be able to talk to each other, but they do NOT have to be in the same subnet (local network). As long as you assign valid public IP addresses (i.e. for your intranet) and set the SE network configuration to point to a router that is plugged into your HMC-SE network, you can load from an FTP server anywhere in your network. I would suggest that you use the firewall functions of that router to allow only outbound TCP connections from the SE, as the SE uses passive ftp. Of course, if you have an application firewall, it will handle active and passive ftp, opening the needed ports on demand, in the correct directions.

Re: LOAD from ... SERVER option?
James, You say your virtual tape is available at that site. Could you create standalone IPLable tapes of ICKDSF and FDR and IPL from the tapes when needed? Dana -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: LOAD from ... SERVER option?
I can't think of a way to directly do what you want. Do you have control at the remote site? My thought (possibly insane) is to put up a PC running Linux which has two ethernet NICs. One the same back-end network as the SE. And one on the LAN segment that you're using to get to the HMC. On this Linux box, I'd put up a proxy server. This would be more secure than just putting the SEs on the same segment. I did a Google search and found this: http://linuxpoison.blogspot.com/2011/02/transparent-caching-ftp-proxy-server.html Or you might want to go with a vendor solution of some sort. I'm sure Cisco would love to help you with this. Hook'em Horns! (no, I'm not a UT alumnus) On Tue, Jan 22, 2013 at 12:54 PM, Lund James E james-l...@tamu.edu wrote: Howdy, So, where to start...

Re: LOAD from ... SERVER option?
James, I use the Load from Removable Media or Server function on the HMC frequently, for many purposes. We run z9s, z10s and z196s. I always access HMCs via their web interfaces. All of our mainframes are in two sites 17 miles apart. They are mirrors of each other and except by special permission, no one is allowed in these buildings. They are patroled by armed guards. I usually load from an FTP server, I have IPLed from a DVD drive on an HMC, on occasion. I don't have any problems, so I don't understand your question. What problems are you having? I can send screen shots, if you tell me what you're trying to do. Harry Date: Tue, 22 Jan 2013 18:54:41 + From: james-l...@tamu.edu Subject: LOAD from ... SERVER option?
