Re: Server doesn't listen error

The problem is resolved now. It occured to be caused by two things:
first human factor - I made a typo in server's IP address (have
several remote machines and confused Linux machine with one of
Windows' ones), second was the OS factor - somehow, although local
host connection on port 5432 was allowed, the firewall denied outgoing
connection through this port. Turning off the firewall solved the
problem.

Thank You for all your advice and input on this topic I learned new
things in terms of diagnostics and realized how much there is still to
learn. Thank You once again.
