Use START LISTENER to start a channel listener.
Notes:
- On UNIX systems, the command is valid only for AIX, HP-UX, Linux,
and Solaris.
- On z/OS:
- The command server and the channel initiator must be running.
- If IPADDR is not specified, the listener listens on all available
IPv4 and IPv6 addresses.
- For TCP/IP, it is possible to listen on multiple addresses and port combinations.
- 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.
- 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.
- 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.
- 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.
