Re: Intermittent FTP Failures

[Mitch Davidson <davidson_l@xxxxxxxxxxxxxxxx>]

I haven't *intentionally* enabled SSL, in fact I've tried to very
carefully avoid going there. (I did try to read all the documentation I
could find concerning SSL within the Management Central Server.  There's
PTFs specific to that scenario, I saw them when I waded through the
README with the Client Access Express servicepack SI02795;  it looked
like more than I was ready to attack at that time, and couldn't ever
find a good solid recommendation to do it.  Since it seemed to be
optional, I opted not to do it.)  This all seemed to be aggravated by
the V5R1 upgrade, which also necessitated a rebuild of my Operations
Navigator and most of the Management Central piece got replaced.  The
new kid on the block was the "Extreme Service Personalized" method and
getting the latest & greatest Universal Connection Wizard.  It truly
would not surprise me to find that one of the connected pieces there is
the culprit;  LOTS of fine print in the associated doc for that and the
ink seemed to be still wet.  One place for sure said that a requirement
was 5722-JV1 with options 3, 4 or 5 installed;  not knowing any better,
I just installed option 5.  When I tested the connection, I got an error
message that said "Option 3 was missing".  Well, gee!  What a &*$$#@!
surprise!

In the back of my mind, I am getting this nagging feeling that maybe it
isn't so optional after all, maybe one of the miscellaneous and fleeting
TCP/TFTP/TMFTP under-the-covers inter-server messages/tasks is trying to
deliver something and assumes SSL is available?  (That'd be a bug;  I
know it is truly bugging our shop.)

The client in question is TCPIP4VSE from Connectivity Systems, Inc.
running on our VSE system.  We FTP 20-30 files from that platform on a
nightly basis, and a couple of times a month (it's turning out to be
more like a week with V5R1) the FTP job stops-- usually after it is well
into the transmission.

Mitch,

>From the SSL.H header file:

In V5R1 you have SSL available for FTP server connections. V5R2 has it
for
client connections. In order for the server to do SSL you have to enable
it
in OpsNav. My guess is that some client is trying to do an SSL FTP
session
but your V5R1 system is not configured for it. Or perhaps a bug?
