Re: Replacing a LAN console

Each PC that connects gets a "token" from the i when it connects - this is
meant to be a security mechanism; the system looks for this token each tmie
a connection is made to the same SST device.

The new PC can't connect because the security token that was generated and
placed on the old pc when it connected to the QCONSOLE device is not
available. When IBM reset the connection (the 65+21 stuff a week or so ago)
they cleared this out but it woudl have been re-created on the next
successful connection.

If the old pc is working, connect it up again and create some additional
sst devices and sst users. Use the new device names and passwords on the
new pc and all should be well. Henceforth use a new device name each time
you need to create a new connection when a PC dies.

This is only to be a simple replacement. One pc swapped out and

was enabled. If I uncable the new pc and attach the network cable to
the dying (not dead yet) pc, it works. Same Version of Windows.
Service pack is the same on the two computers. Same IP address - only
one plugged in at a time. The dump taken with SST shows many attempts
to connect with port 3100. No firewall on the pc. I keep wondering
if I have CA installed correctly. I can't recall the option I took.
I think tomorrow, I will either uninstall/reinstall CA or look at
modifying it.

Nothing exceedingly simple has jumped out for IBM.

John, I find it strange. Lan console is a PITA sometimes, but not THAT
much.
Remember a few critical points:
Each and everyone of the PCS you choose to be Lan Console create their
own
certificates and must use separate QCONSOLE devices.
Therefore, if you have access (even for a while) to a working console i
recommend you go to the DST and create a bunch of QCONSOLE with default
passwords.
Then it should only be a matter of creating a connection, using one of
those new qconsole devices and it should work.
You cant share qconsole devices and i believe neither you can share IP
addresses.
Give it a try.

Today was another headscratcher. Still does not work. I performed a
dump for Tony and sent it to him. One issue that sticks out is
difficulty with port 3001. I can't help but wonder if I failed to
properly install something. I can't recall the option I selected for
the install. Could a missing piece cause a problem with port 3001?
There is no firewall on the pc and there are no port restrictions on
the network. This morning, the old dying pc was started and it
worked. Then, I removed the network cable from the old pc and
attached it to the new pc. Same IP address and net mask for both
computers. Thus my wondering if I selected the wrong option or needed
to install something else.

Anthony wants me to install CA on a laptop and connect to connector
T5. Purpose is to prove the network is not the issue. But, this is
the same network cable, just moved from one computer to another.

Any ideas?

I forgot one other little detail. Currently, the new and old broken
LAN
consol pcs are in a room next to the room containing the i.
Despite the detail that a ping from one to the other works, he wanted
me to
move the pc into the room with the i, and directly attach to
connector
T5.
Light in that room isn't the best. Used to be a flashlight there as
well.
I could not find a T5 connector. This was to rule out a network
issue.
But, network worked just fine until original LAN console pc died.
Did
his
suggestion have merit?

There is a pc in the computer room. Only has 5250 emulation on it.
When the mess happened before, it was sufficient, barely, to
resolve
that issue. Boss said there would be no backup or IPL this
weekend,
to avoid a potential additional headache. The headache of the
unknown.

Easy.
The third PC was, as Rob mentioned, mostly for backup (or because

Short of an HMC, this is the best option available.

I gathered I could, based on the screen inquiring if I wanted to
take
control. Issue then becomes a matter of communication. The
system
is almost totally unmonitored. No dedicated people to serve as
"operators".
So even knowing who will be operating is a bit of a challenge.

The boss would not want to complicate things too much. He also
functions as
an operator every other weekend doing backups. It is all very
strange.
But, this is on a prolonged death spiral. May be running another
year.

I was wondering about the sequence of buttons I pushed to clear
"something"
on the i that prevented the current console from connecting after
I
trashed
the config and rebuilt it exactly as it was. Whay was that an
issue?
What
was going on? Will multiple consoles cause a repeat? The last is
important
especially since I have no idea who will be using the console.

Granted, with HMC, it's been awhile since I've used Lan Console.

Sent by: midrange-l-bounces@xxxxxxxxxxxx



I used the wrong term last week. It was NOT an OPS console. It
is
LAN console.

After getting the thing to work last week, I come in this morning
to
see that the thing had died. I don't know why it needed to be
rebooted, but Windows had a problem finding a DLL. Many reboots
later, I saw that different pieces were mysteriously "missing".

For the moment, it is working. It is an MPC. Looks like a
bloated
LCD display, but it is computer built into a monitor. I tried to
get into BIOS setting, with intent of running SpinRite. I
believe
I
will pass on that.

Boss wants it replaced, and there is a much newer computer
available.

Point of this post, if somebody reading this has not given up, is
confusion I have. After I deleted the LAN configuration from the
pc, which Windows had no problem doing, I built a new console ,
per
request from IBM. Initially, Windows would not allow the new
configuration to be stored. Had no issue with me deleting a
configuration. Seems odd. But, anyway, new configuratio was
finally stored. Console would not connect to the i. But, this
time, an error popped up which Tony knew how to fix. It involved
going to the i front panel and entering a number of codes. I
can't
remember what they were. Seem to remember one sequence being
repeated maybe eight times.

Ok, during start of the current LAN console, there is a point
where
the option to take control is presented.

My issue is what the heck was I clearing on the i and is that a
factor in replacing the console computer?
