RE: Intermittent problem with FTP client V5R2 over PPP

["Carl Galgano" <cgalgano2@xxxxxxxxxxxxxxxxx>]

Marty, all good suggestions.  
The comm adapters are different between my machine and the customers, also
the modems, I am using a UDS V.3xxx and the customer is using an IBM
7258-400.
The standard IBM FTP client does hang as well.  Sometimes it works
perfectly, other times it does not.  The modem is external, but I am in
Atlanta, with the systems group, the AS400 and other hardware is in Omaha,
so looking at the modem is out.  They have a production box I am going to
load up as well and see if the problem follows the box, the OS or the
hardware.  That will give me an idea where to hunt next.  It appears the
entire PPP link locks up, rather than just my FTP session.

Carl,

Besides the OS, have you considered the hardware angle - differences in comm
adapter, modem, modem configuration?

You said "intermittent". Do the standard IBM FTP clients work some of the
time over the PPP connection on customer's machine?

Any chance you're using an external modem and can get a look at it when it
locks up? That might tell you something.

When the FTP session locks up, can you start another one, or telnet, or
ping? (just trying to determine if the whole PPP link is locked up).

I am having a frustrating problem with some code that I am testing.
Basically the code starts a dial up PPP session (to a bank) from the
iSeries, after connected, it FTPs a file and then quits.  The code was
developed on my 5.1 box and has worked flawlessly (in order to test the
error trapping and recovery I had to unplug the modem, the thing never
failed!). Today I moved the code to my clients system.  Only different is
they are running V5R2.  There is no SSL, just plain old FTP.  To verify it
is not my code, I just tried to manually start the FTP client, connect to
the remote system and enter commands.  The FTP client hung up on me.  So, it
is not my code, the only thing left to suspect is the OS. A quick search of
the archives did not bring up this specific problem.  Can anyone shed any
light? cjg
