CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

The message CCL8402I also indicated that the JSSE libraries were selected.
This is because we had supplied the name of a keystore file in the CTG.INI
file. The CICS TG also outputs a long list of the ciphers that are enabled in the
JSSE SSL protocol handler.
3. We checked the state of the TCP/IP sockets on our UNIX System Services
TCP/IP stack using the onetstat command from OMVS. This showed us the
output in Example 8-13 and indicates that the Gateway daemon was indeed
listening on port 8052 and 8062 for requests.
Example 8-13 Partial output from the onetstat command

We could have checked the ports were listening using the ScanPort utility. For
further information see “Testing the configuration” on page 52.
4. Next, we checked basic IP connectivity from our Windows 2000 workstation to
our z/OS system using the ping command from a Windows 2000 prompt (see
Example 8-14).

Once we knew everything was working, we then tested from a Windows 2000
workstation. We performed the following steps:
1. We set the CLASSPATH on Windows 2000 to include ctgclient.jar and
ctgsamples.jar using the following command:
