Re: nscd [was] how do you run postgres without dns server

Do you got "hosts: files dns" in your nsswitch.conf?
Otherwise , /etc/hosts won't be used.


-----------------------------------------------------------------
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         compat
group:          compat
shadow:         compat

hosts:          files dns
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis
