I was thinking it would be cool to have a small utility that wouldallow youto enter an option on a source member in PDM, prompt on it, and thenselect
the predefined FTP location (or a create a new one) of where the source
should be sent to.  The destination iSeries would need to have the same
small utility loaded so it could easily go and retrieve the sourcefrom theremote FTP location. I realize that for one time source codetransfers thisis a lot of steps, but if you need to transfer code even twice it suredoesbeat trying to copy/paste into an SEU window.

Aaron:

Some of this request was confusing because of the originally statedcondition that the two client systems were not on the same LAN. Thatseemed to open the possibility that the two systems had no route betweenthem. Also, your later comments bring in firewall port restrictionsbetween clients -- and of course firewalls will be a problem no matterwhat protocol is used for communications.

But if an internet route exists and ftp can be done from one to theother, then...

You might want to do some reading in the RFC for ftp. There arecapabilities that are rarely used or discussed. One feature that mightbe particularly useful to you is using your PC to start ftp-controlsessions to the two client systems and telling them to open an ftp-datasession between them. I.e., your PC is in control but the data routedirectly from one client system to the other.


To get you thinking, try reading:

http://www.ietf.org/rfc/rfc0959.txt

...starting down at [Page 8], the paragraph beginning "In anothersituation a user might wish to transfer files between two hosts, neitherof which is a local host." The little text-diagram following thatparagraph is pretty simple, though it can take some practice to get itworking.

Maybe you can manipulate this ability by way of some simple PCscripting, etc.

Even if you can't get different client systems linked together, thereseems to be the chance that your mowthelawn.com site can act as anintermediary... So, if you can ftp between two remote hosts, I supposenothing stops you from doing it between three remote hosts or switchingprotocols in the middle...
