* Problem: pg_hba.conf is automatically rewritten every day

Hi everyone,
Every day, the file pg_hba.conf in my server is rewritten and
postgresql received
a SIGHUP to reload configuration. The pg_hba.conf content is:
=============================================
.......
......
local samerole all md5
host samerole all 127.0.0.1 255.255.255.255 md5
local all postgres md5
host all postgres 127.0.0.1 255.255.255.255 md5
=============================================
As a result, my application cannot connect remotely to the database on
server. I have to manually modify the pg_hba.conf every day. I don't know
why that happens? Is there any way to get rid of it?
Thank you very much for your help.

Sounds like some sysadmin scripted rsync gone wild.=

Hi all,
I am the root user (except that my dedicated server is under the control of
its company). I don't have any sysadmin script. The problem just suddenly
occurs. I don't know why?

as best i know, with the standard postgresql installations, there is no
component that modifies the pg_hba.conf file.
from the systems perspective, it is a static config file, like postgresql.conf
some external script/facility/action is updating your pg_hba.conf file,
and that external script/facility/action is likely unique to your environment,
os installation, server management facilities.
if the timestamp of the file is being set to the same time every day, you
might check the following files:
(may or may not be on your system)
/etc/crontab
/etc/cron.d/*
/var/cron/crontab/*
/var/spool/cron/crontab/*
grep for the timestamp in:
/var/log/cron*
/var/log/auth* (remote system automatically doing sysadmin via ssh?)

Would it make sense to make the file read-only and see if a write error pops up somewhere?

Look at the timestamp of when this file [pg_hba.conf] is updated and see if
there is any correlation to system messages [/var/log/messages or
equivalent of your kernel].
Thanking you,

Hello,
I have found the reason. It is due to an update of cpanel. According to its
author, to "automatically secures the pg_hba.conf file":
http://forums.cpanel.net/f354/cpanel-update-changed-pg_hba-conf-samerole-338982.html
Thank you very much.
