Re: ACS sessions disconnecting -- PCTECH

This has been RESOLVED. Hang on for the ride.

We have set up on GoDaddy, a DNS record pointing to ouribmi.dilgard.com
that points to one of our external IPs. The Meraki router then sends that
to our IBM i. Internal DNS has ouribmi.dilgard.com pointing directly to
our IBM i. (It's not really "ouribmi.dilgard.com" that's just what I'm
telling you.)

What this does is allow our salespeople to use Mochasoft 5250 either
internally or externally and double-click the same desktop icon and get a
5250 session over SSL. Whether they're in the office or not.

A few months back we replaced the internal Windows DNS server with
redundant Linux DNS servers. Unbeknownst to me, the firm setting them up
failed to put the ouribmi.dilgard.com record in there.

The Meraki evidently had ouribmi.dilgard.com cached because everything was
fine until just a few weeks ago when it got a firmware update. Right after
that those 2 desktops started having the disconnect issue.

Just yesterday I went in to the internal DNS because I was running out of
ideas. I could not find an entry for ouribmi.dilgard.com. Light bulb goes
on. My desktop ACS uses the hardcoded IP address for the IBM i. I changed
it to ouribmi.dilgard.com and MY sessions started disconnecting. Eureka!

The desktops with the issue used ouribmi.dilgard.com while everyone else
had the IP hardcoded. I switched them to hardcoded IP and the disconnect
stopped. They were going out onto the internet to come right back in here.

Gotta get the guy to put in the ouribmi.dilgard.com record.

Then again, unless those cables are in really bad shape, it's highly
likely
that's not the problem.

Except I can swap cables in less time. :)

Before you swap cables have you called IBM? They'll most likely have
you do comm traces, but then again there might be a setting none of us
are thinking about/remembering too.

Anyone got any ideas? It's still happening. I'm about ready to start
swapping out cables.

Arrgh. Forgot to add: We also have Mochasoft and those sessions do
NOT disconnect.

All,

V7R1, using ACS.

About 2-3 weeks ago, on 2 of our Windows 10 desktops, the 5250
sessions started disconnecting after a relatively short period of
non-use. Like maybe 10-15 minutes. One desktop is local, the other

is

remote via VPN.

These are the only 2 desktops doing this, all other desktops (Win 7
and Win
10) are fine. For that reason, I'm assuming it's something at the PC
level, hence posting to this list.

You can reconnect with a mouse click.

The night before this started, our Meraki MX60 routers received a
firmware update, but I don't see how that would affect this. But I
thought I'd mention it.

I'm concentrating on the local one right now because it's easier to
troubleshoot local.

I have checked the power settings of the desktops. They never go to
sleep.

In ACS, I went to Communication/Configure/Advanced and set Keep-Alive
to yes. No joy.

In ACS, I went to Communication/Configure and set Auto-Reconnect to

yes.

No joy. (But the use did notice.)

The local one has had 2 java updates since and still no joy.

What else should I be looking at?

Thanks.
