Information about the SSL/TLS optionWith the Secure Sockets Layer (SSL/TLS) protocol, it is possible to establish a secure connection between the AS/400 and a Telnet client. Our product uses the SSL/TLS layer included with the Windows OS.
Limitations in Mocha TN5250 SSL:
- No validation of the Certificate from the AS/400.
- Client Certificates are not supported.
A Certificate is used for the AS/400 to proving its identity. We have selected not to include such an option, as to keep the use of SSL/TLS as simple as possible. For most customers the main reason to select the SSL protocol, is to make the data traffic secure.
On how to enable and disable use of certificates on the AS/400 , see IBM document : step 3, #10 (yes/no)
IBM AS/400 Information Center includes a number of publications about SSL issues.
Make a search for telnet ssl or try i400 Technical Studio (TCP Reference) and select Select Trouble shooting SSL-enabled Telnet server.
This Web page includes a summary of how to build an AS/400 system with SSL support.
We assume you will NOT use an external Certificate Authority, but generate local digital certificates for your system.
Digital Certificates are used to verify the TN5250 User is in contact with the correct AS/400. In most SSL installations, this is not a big issue. The reason for using SSL, is to create a secure encrypted session, meaning it is not possible with a net sniffer to see password or user data.
1. Install following AS/400 software programs on the AS/400 (V4R4)
2. Configure the Digital Certificate Manager
- Digital Certificate Manager (DCM), option 34 of OS/400 (5769-SS1)
- TCP/IP Connectivity Utilities for AS/400 (5769-TC1)
- IBM HTTP Server for AS/400 (5769-DG1)
- One of the IBM Cryptographic Access Provider products: 5769-AC2 (56-bit), or 5769-AC3 (128-bit). Notice AS/400 Model 150 uses products 5649-AC5 and 5649-AC6
2.1 Start the HTTP Server on the AS/400 as an ADMIN instance.
Issue following AS/400 commands:
- GO TCPADM
- 5. Start TCP/IP servers

- Server instance *ADMIN
2.2 Start a Web browser as Internet Explorer 4.0/5.0/6.0 on a PC.
Select URL http://your_system_name:2001 A screen with 2 major options will be displayed. Select Digital Certificate Manager
A new screen with a menu is displayed. Select Certificate Authority (CA)
Select Create a Certificate Authority, and fill out the form. In our test case, we selected key length 512.

Click the button next to the application QIBM_QTV_TELNET_SERVER.
Select Work with system certificate

At an AS/400 prompt write:
4.0 Verify the Telnet Server is ready for a SSL session
At an AS/400 prompt write:
If the Telnet server is ready, a local port with the text telnet- should be displayed. Actually the port text is telnet-ssl, but it is truncated in the default display.
5.0 Start Mocha TN5250
If Netstat displayed the correct information's, start mocha w32 tn5250, and select menu - file - connect - advanced -
Enable the SSL option.
Press Ok , Ok, and if the SSL session works correct, the status line in mocha tn5250 will display ONLINE-SSL.
If it does not work, check the IBM documentation for the AS/400. We can only offer very limited support on AS/400 configuration. Please use the IBM support function for such issues.
