Thread: Impossible to bind to a specific IP address

Impossible to bind to a specific IP address

From

Hi,

As far as I can tell from the documentaion, it is impossible to tell the
postmaster daemon to bind to just a single IP address - only to a
specific port on all IP addresses. This makes hardening the box
postgresql is running on impossible.

Is there a workaround to this? (other than trying to firewall off the
ports - the box needs to be protected from other boxes nearby - it is in
an insecure environment).

Regards,
Graham

Sure you can, assuming you're running a current release.  See
VIRTUAL_HOST config parameter or equivalent -h commandline switch.

In 7.1.X you can bind to a specific IP.  See postmaster -h flag.  Not
sure about 7.0.X releases.
