Обсуждение: Problem binding postmaster to several interfaces

Hi everyone!

I have postgresql 8.0.1 installed on a Slackware Linux machine. The
machine is a multi-purpose device and it has external and internal
interfaces. I would like to limit "postmaster" to listen only to the
internal interface and the loopback. I tried to use the new
"listen_addresses" directive but with no success so far. I tried
several forms - I either got a syntax error, or the "postmaster"
continued to listen to all interfaces - (0.0.0.0:5432 as shown by
"netstat -tupan" command).

Any ideas?

The current value of my "listen_addresses" setting is:
listen_addresses = '192.168.0.1, 127.0.0.1'

but using "netstat -tupan" I still see:

tcp        0      0 0.0.0.0:5432            0.0.0.0:*
LISTEN      10042/postmaster

The contents of the logfile for the last reboot is:

2005-02-14 14:14:55.105721500 LOG:  received smart shutdown request

The server was build with:

./configure --prefix=/usr/local/postgresql --with-openssl
--with-python --with-php=/usr/src/php-4.3.10 --enable-nls

The system is Slackware Linux 9.1.0 with kernel "Linux xxxxxxl 2.6.10
#1 Wed Feb 2 22:59:49 EET 2005 i686 unknown unknown GNU/Linux".

Nothing wrong with that.

Are you by any chance using "-i" on the postmaster command line?  That
overrides whatever you put for listen_addresses in the config file.

Yep, that was. I use custom script for supervising postmaster with
daemontools. And I failed to notice this change in the behaviour in
v8.0.

Thanks a lot.
