It is actually just a proxy, it connects to the telnet daemon on the BSD box as well as allowing the AS/400's telnet client to connect to it. It then acts like an expect script to type commands in for the user -- that way a non-technical user can type a menu option on the AS/400, and it'll log into the BSD box and do things without them needing to understand how to do them. a few things I use it for: 1) Saving data to floppy. The AS/400 program makes a SAVF, FTPs it to the BSD box, then uses the expect-like program to to log on to the BSD box and save it to floppy, spanning floppies where needed. (Also can restore the same stuff...) 2) Talking to our bank. We dial in, navigate the bank's menus and then use XModem to send/receive direct deposit and check reconciliation info. Rather than buy software for the AS/400, it was easier to use the open-source software that already exists for FreeBSD. This also saved us having to buy seperate modems for the BSD box and the '400 3) Err... I know I use this for some other things, but I can't think of them off the top of my head. At any rate, this method works well because the user doesn't need to know what to type, it types it for them. But, on the other hand, they can see exactly what's going on, so if something unexpected occurs it's visible on the screen and the person running the option can apply intelligence to the situation. (Which usually means calling me.. heh) I'd love to convert this to SSH to eliminate the need for running the telnet daemon. But -- for the time being telnet is pretty safe, since I have it firewalled off from outside the LAN...
