2. We checked the CICS TG log (displayed when the CICS TG is started) for the
message CCL6524I indicating the TCP protocol handler had started (see
Example 9-13).

protocol.
3. We checked the state of the TCP/IP sockets on our Linux machine using the
netstat -l -n command from a Linux command prompt. This showed us that
the CICS TG was indeed listening on port 2006 for TCP requests (see
Example 9-14).
Example 9-14 Output from the netstat command
tcp 0 0 0.0.0.0:32768 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:79 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:2006 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN
4. Next we checked basic IP connectivity from our Windows 2000 workstation to
our Linux system using the ping command from a Windows 2000 prompt (see
Example 9-15), and from our Linux system to our z/OS system using the ping
command from a Linux prompt (see Example 9-16 on page 227).
Example 9-15 Output from the ping command on Windows
