START LISTENER

 

Compaq NSK HP OpenVMS i5/OS UNIX systems Windows z/OS

For an explanation of the symbols in the z/OS column, see Using commands in z/OS.

Use START LISTENER to start a channel listener.

  1. On UNIX systems, the command is valid only for AIX, HP-UX, Linux, and Solaris.

  2. On z/OS:

    1. The command server and the channel initiator must be running.

    2. If IPADDR is not specified, the listener listens on all available IPv4 and IPv6 addresses.

    3. For TCP/IP, it is possible to listen on multiple addresses and port combinations.

    4. For each START LISTENER for TCP/IP request, the address and port combination is added to the list of combinations upon which the listener is currently listening.

    5. A START LISTENER for TCP/IP request fails if it specifies the same, or a subset or superset of an existing, combination of addresses and ports upon which a TCP/IP listener is currently listening.

    6. If you are starting a listener on a specific address to provide a secure interface with a security product, for example a firewall, it is important to ensure there is no linkage to the other non-secure interfaces in the system.

      You should disable IP forwarding and routing from other non-secure interfaces so that packets arriving at the other interface do not get passed to this specific address.

      Consult the appropriate TCP/IP documentation for information on how to do this.

  3. On i5/OS, OS/2 Warp, UNIX systems, and Windows, this command is valid only for channels for which the transmission protocol (TRPTYPE) is TCP.
