IBM iSeries Access for Windows PC5250 Configuration for HMC Remote Console Connections

Technote (troubleshooting)


Instructions are provided to configure the 5250 emulator included with IBM iSeries Access for Windows for a Remote Console connection to the HMC.

Resolving the problem

This document provides detailed instructions for configuring the 5250 emulator included with IBM iSeries Access for Windows for a HMC remote console connection. This configuration is for a non-SSL connection to the HMC. The configuration does not apply to other emulators such as the IBM Personal Communications product. For further information, refer to the IBM eServer Information Center topic Connecting to a 5250 console remotely at the following Web site:

Step 1: Verify the iSeries Access for Windows code level.

The iSeries Access for Windows emulator being used must be at Version 5 Release 3 Service level SI13587 or later. Since there have been many updates and revisions to the program it is recommended to use the latest level and service pack available. Any version used less than the latest may result in unpredictable results.
To verify the service pack level, select Start > Programs > IBM iSeries Access for Windows > iSeries Access for Windows Properties.

In the Properties window, the Version, Release, Modification level, and Service level are seen on the General tab.

Note: The V7R1 "EnableTelnetKeepalive=Y " setting is not supported.

Step 2: Configure the PC5250 remote console session.

1. Select Start > Programs > IBM iSeries Access for Windows > Emulator > Start or Configure Session.
2. From the IBM Personal Communications - Session Manager dialog that appears, click on the New Session... button.
3. In the Configure PC5250 dialog, do the following:

a Update the System Name to the HMC host name or TCP/IP address.
b Set the port number to 2300.
c Press the Properties button.

The System name value and Properties buttons are circled in the Configure PC5250 print screen.
4. The properties button will launch the Connection dialog shown below. Do the following:

a Set the User ID sign on information to Use default User ID, prompt as needed.
b Set the User ID to Q#HMC.
c Set the Security to Not secured.
d Click OK, OK.
    The parameters specified in Steps 4 a-c are circled.
5. Save the profile.

To save the workstation profile configuration for future use, click the Menu option, File then Save. Enter a profile name and click OK. The workstation save creates two files. Both file names are the same as the profile name with extensions of .ws and .cae.

Note: Do not move or copy only the workstation profile file (extension .ws). Moving only this file will result in the loss of the connection information, which causes a CWBCO1048 connection error. When possible, create a shortcut to the profile rather than a copy. If the profile must be moved or copied, copy both files to the new location.

Step 3: Verify the HMC firewall configuration for V6 or earlier version of HMC Code.

The firewall must be enabled for remote console, regardless of the type of emulator used. This information is not specific to the iSeries Access for Windows product.
1. In the navigation area, expand the HMC you want to work with. HMCs are listed by host name or TCP/IP address.
2. Expand HMC Management.
3. Click HMC Configuration.
4. In the contents pane, click Customize network settings.
5. Click the LAN Adapters tab.
6. Select the LAN adapter you want to work with and click Details.
7. Click the Firewall tab.
8. Select the 5250 application in the top table. Click Allow Incoming to allow all TCP/IP addresses or click Allow Incoming by IP Address to allow only specific addresses. Click OK. 5250 should now display in the Allowed Hosts table.

Graphical Menu options illustrate the location of the items used in Step 3, 1-8.

Step 4: Verify the HMC firewall configuration for V7 version of HMC Code.

1. In the navigation pane, select HMC Management.

2. In the right pane, select Change Network Settings.

3. In the Customize Network Settings dialog box, select the adapter connected to the network and select Details.

4. In the LAN Adapter Details dialog box, select the Firewall Settings Tab.

5. Ensure that 5250 is listed in the allowed hosts frame. If it is not, select it in the Available Applications Frame and select Allow Incoming.
