Troubleshooting


Problem

An error, 600E 000001F7, occurs when using a IBM Host On-Demand session with telnet SSL secured by a Verisign® certificate.

Diagnosing The Problem

The following error appears when attempting to start a secure SSL connection with a z/OS® telnet server using a Verisign certificate:

10:53:53 EZZ0053I COMMAND VARY OBEY COMPLETED SUCCESSFULLY
11:05:28 EZZ6034I TELNET CONN 00000063 LU **N/A** ACCEPTED 2323.

11:05:33 PARM1: 000001F7 PARM2: PARM3: GSK_SECURE_SOCKET_INIT

Resolving The Problem

Add both the Verisign Root CA and Intermediate CA certificates to the key ring in RACF.

Note for Intermediate certificates:

  • As well as issuing SSL Certificates, the Trusted Root CA certificate can be used to create another certificate, which in turn will then be used to issue SSL Certificates.
  • As the Intermediate Certificate is issued by the Trusted Root CA, any SSL Certificates issued by the Intermediate Certificate inherit the trust of the Trusted Root, effectively creating a certification chain of trust.
