3. Perceived 5250 Host Problems
The first problems in this category are for when there are other users who have Telnet
sessions working.
Problem 3.1
You do not know the IP Address of the AS/400.
Solution
You will need access to the AS/400's command line from another terminal device or your
system administrator to provide you with the correct IP address for the AS/400 that you
want to connect to. For those that don't know, or would like to know the AS/400
command is as follows:
1. After signing on to the AS/400 with the appropriate privileges, from the command
line type CFGTCP followed by the <enter> key.
2. On the next screen, select option Work with TCP/IP Interfaces, by typing a 1 and
then <enter>.
3. Locate the interface that you are going to connect to. (If you only see 127.0.0.1 this
means TCP/IP has not been properly configured on your AS/400. DO NOT use
127.0.0.1.
If you do so you will NEVER get a sign on from the AS/400. If TCP/IP is not configured
on your AS/400 we recommend you follow the instructions from IBM. The name of the
book is called "Getting Your AS/400 Working for You". Publication number is SC41-
5161-00. You'll find helpful information on TCP/IP in Chapter 6.) Write down the IP
address and enter that in the MinIT 6000 configuration for this session’s Host
Configuration – IP Address.
Problem 3.2
It was working. The light on the MinIT 6000 is green. The MinIT 6000 host session is
black, with no cursor.
Possible Cause 3.2.1
You have lost your IP connection. You could have a cable break, hub, bridge, or router
down. This means that you are not accessing a valid IP address, or the Ethernet line is
not up or MinIT 6000 or the host configuration was changed.
Action
1. Verify physical connection. Viewing lights is the usually the quickest way to do this.
2. See if others users are working, if not check the AS400 configuration.
3. Swap devices if possible to see if the problem follows the device in question.
Possible Cause 3.2.2
Disconnecting the session when you are not at a signon screen could cause this problem.
This could also happen if you had a power outage and MinIT 6000 crashed and you had
to re-boot. The AS/400 still has your session active, although in a crashed status.
Solution
If the last device using this station address crashed, the station address may be varied off.
Ask the System Administrator to vary your device on. This may require varying off, then
