Hello Answer Gang,
|
|
</STRONG></P>
|
|
<P><STRONG>
|
|
Let me start off by thanking all of you for providing such excellent
|
|
service.
|
|
</STRONG></P>

I'm running RedHat 6.2 with apache 1.3.9 and Sendmail 8.9.3 as an Internal
|
|
web/mail server.
|
|
I use it on a daily basis, but haven't changed any of the configurations
|
|
since the initial install. Yet mysteriously the httpd.conf and the
|
|
sendmail.conf files becomes null (file size of 0)!!! This occurs randomly
|
|
and usually after a reboot of the system.
|
|
</STRONG></P>
|
|
<P><STRONG>
|
|
Since it is internal and no one uses it except for myself, I have no way of
|
|
explaining why this is.
|
|
</STRONG></P>
|
|
<P><STRONG>
|
|
Do you guys have any ideas???
|
|
</STRONG></P>

Wow. That's odd. <EM>Very</EM> odd. It sounds like maybe some sort of a config
|
|
file backup procedure (?) gone wrong. One of the first things I'd do is
|
|
switch to "<TT>/etc/init.d</TT>" and grep the scripts there for any mention of the
|
|
above files. I'd investigate anything I found with a <em>very</em> sceptical eye,
|
|
possibly looking for evidence of intrusion (I can see some script kiddie
|
|
being very interested in those two files...) or just a badly-written
|
|
script.

If you can't find anything, try setting the immutable attribute on those
|
|
files via "<tt>chattr</tt>" (see the manpage); this should at least stop them from
|
|
"disappearing". I, for one, would be <em>very</em> interested to know what you
|
|
find out in your troubleshooting process.
