Обсуждение: default port number
Hi Everybody,
I had been running postgres with postgresql.conf file
as little changed as possible from distributed version.
And lately I became a bit curious as well as confused.
In my configuration file both lines
#listen_addresses = 'localhost'
and
#port = 5432
are commented out.
What does this mean? Is postgress listening on port
5432?
Regards,
Tena Sakai

Thank you, Kevin Kempter.
Thank you, Kevin Grittner,
In order for me to accept foreign odbc connection,
one of the things I must to is to change
listen_addresses = 'localhost'
to something like:
listen_addresses = 'ip-address-A, ip-address-B'
But those machines on the list are dhcp clients
and their ip addresses change from time to time.
Is there something I can do to accomodate such
moving targets?

The above values are the defaults, postgres should be listening on port 5432
and only listening on localhost for connections. You can double check by
running these commands in a psql session:
show listen_addresses ;
show port ;

You can use hostnames instead of I.P.'s or you can set:
listen_addresses = '*'
Note that just because postgres will listen to all hosts ('*') the actual
authentication access is controlled by pg_hba.conf

Many thanks, Kevin.
'*' is a bit too wide for my taste. I wonder
if it is possible to specify something like
network mask (or range)? I may be a bit
paranoid, but...

Hi Kevin.
I had to read your message twice and look at
pg_hba.conf file, but I am now clear. Yes,
a big difference between listen *on* and
listen *to*.
Many thanks.

This is not the IP list you will listen *to*, but the IP list you will
listen *on*. (You may have multiple network adapters and not want to
accept connections on all of them.)
To limit the IP addresses which can connect to the server, see the
pg_hba file.
