Piotr,
Oracle docs indicate a default file location
of "
/etc/ssh/sshd_config", but that if the SSHD daemon is started with the "-f" switch, another file location can be specified. Running the UNIX/Linux command "
ps -eaf | grep sshd" might reveal whether the daemon is reading from a non-standard location for the configuration file.
As for the listener problem, I'm not quite sure what produces that fault, but looking at your screenshot and noticing that your listener is using non-standard port 1522, can you check that database instance to ensure that the Oracle initialization parameter LOCAL_LISTENER is set appropriately?
Please let us know what you find?
Thanks!
