The information provided applies to the Informix Server Version 11.70.xC2 and later.
The Informix Warehouse Accelerator Admin Guide states as requirement that the "telnet command" must be available. This means:
- The "telnet command" required in the documentation is the
telnet client program. The ondwa script uses
it to communicate with the accelerator via the telnet
- IWA uses the telnet protocol for some rather internal
communication for few administrative commands.
For that purpose IWA is always explicitly configured to
listen at a specific port on localhost (127.0.0.1).
With that, nobody from the outside can connect to IWA
in this way.
- No telnet service is required on the machine where IWA
is running. That means no telnet daemon (telnetd) should
