Good call; don't give any privileges that they don't need.
Well, they don't have to be owned by root. Make them owned by the web
developer's user. Or create a group of "webdevelopers" and make your
developer part of that group with write permissions to the htdocs directory.
Just do not make them owned by the user that the Apache server is
running as.
Why include root? All you need to do is create the webadmin group and
add your web developer(s) to this group. Just remember to enable the
write permissions on the required directories.

| How to PostMortem? Posted: 16 Apr 2004 08:03 PM PDT If your three UPSes have serious surge protectors, then you
can provide the numerical specifications that describe how
well they perform for each type of surge. I keep asking for
and no one has ever been able to provide specs to prove this
protection. Furthermore how does that UPS earth the typically
destructive transient when it is, virtually, not connected to
earth.
You are confusing safety ground with earthing. To be
effective, the UPS must make a less than 10 foot connection to
EARTH ground. That means UPS must be part of or at breaker
box. Building wide UPSes are effective because a short earth
ground is part of the installation. But plug-in UPSes are not
located and connected less than 10 foot from earth ground.
Earth ground - not safety ground - is essential for effective
protection. That fault light reported a safety problem - and
could never report the existence of earth ground. No earth
ground means no effective protection.
Your description of a green wire connection back to breaker
box is an earthing path? But if that green wire does carry
the destructive 'direct strike' surge, then green wire only
induces that transient on all other adjacent wires. Now we
have additional induced transients throughout the building as
well as the direct strike. Not only must the connection from
each utility wire to earth ground be less than 10 feet. It
must also have no sharp bends, no splices, and not be bundled
with other non-earthing wires. Destructive transient must be
dumped into earth before that transient can enter a building.
Well proven concept from before WWII. Green wire ground
violates all three criteria for effective protection.
This problem with a green wire safety ground is why your UPS
manufacture avoids the entire discussion. Notice that
discussion about earthing never comes from the manufacture of
ineffective protectors. But real world (serious)
manufacturers discuss earthing extensively:
http://www.polyphaser.com/ppc_technical.asp
http://www.polyphaser.com/ppc_pen_home.asp
Does not matter if you brother-in-law had two wire
receptacles upgrades to three wire (had safety grounds
installed). That rewiring was essential to human safety and
did nothing for surge protection. Fault light was only
reporting a human safety problem and could never report a
missing earth ground. Again and so important - the less than
10 foot connection. That distance to earth is critical.
Running a dedicated circuit to computers is nice. But it
does not do anything worthwhile for noise or transient
protection - from a computer's perspective. Nothing in the
house creates noise or transients that adversely effect a
computer. Computer power supplies are some of the most
resilient devices in the house. So resilient that this UPS
creates 120 VAC in battery backup mode by outputting two 200
volt square waves with a 280 volt spike between those 200 volt
waves. That so dirty electricity is, to a computer, 120 VAC.
UPSes can output electricity that dirty because computer power
supplies are (must be) that resilient. Worry more about the
power supply for furnace operation or bathroom GFCIs. They
may be more at risk.
Again, does not matter whether a brother-in-law had his
house rewired. Those receptacles are safety ground - not
earth ground. Rewiring his house does not solve a surge
protection problem. These citations have nothing to do with
household wiring and yet define the primary protector for a
home:
http://www.tvtower.com/fpl.html
http://www.tvtower.com/grounding_and_bonding.html
These pictures may be especially important to you (if I have
your location correct) because your electric company - now
called FirstEnergy who also created the NE blackout - may be
same that also created blackouts in Seaside Heights last 4
July. Their top management is nothing but bean counters who
cost control by letting the essential connections (see those
pictures) fail. Many Ocean County residents were electrically
shocked in their swimming pools for same reasons. Again,
these pictures have nothing to do with receptacle ground
wires. They do involve household's primary protector
circuits.
Those pictures affect the residence's primary surge
protector. Second protector is called 'whole house' -
typically located in breaker box and less than 10 foot from
central earth ground. Available for may $1 per protected
appliance (verse how much for ineffective plug-in
protectors?). Protector inside UPS is not considered because
it does not even claim to protect from the typically
destructive transient (again - just read their numerical
spec). It has no less than 10 foot connection to single point
earth ground.
An example of protection cited by an APC product:
SURGE PROTECTION AND FILTERING
....
Normal mode clamping response time 0 ns, instantaneous
Normal mode surge voltage let through <5% of test peak voltage
when subjected to IEEE 587 Cat. A 6kVA test
Normal mode noise suppression Full time EMI/RFI
filtering
Modem/10Base-T/100Base-Tx network cable port single line
(2 wire, RJ11) or network (UTP, RJ45) compatible jacks
Where is the common mode protection? It is not even
claimed.
Your phone line and cable also have effective protection
installed, free, by the utility - if each is properly
installed 'less than 10 foot' to a single point ground.
Again, 'whole house' protectors are so effective that your
telco already installs effective protector inside the premise
interface box (NID) and makes the so important, 'less than 10
foot' connection to same earth ground. Cable needs no
protector since earthing connection is made (as even required
by National Electrical Code) without protector. What did the
APC do? Nothing. Protectors are only as effective as its
earth ground - which UPS manufacturer just forget to mention -
even in the above numerical spec.
Don't fall for the myth that a plug-in UPS provides
excellent protection. It cannot. Again, look at the numerical
specification. It does not even make that claim.
So what is that surge protector inside a UPS? Same circuit
found in power strip surge protectors. That's it. Plug-in
UPS provides same protector circuit found in power strip
protectors. Nothing more. And much less when there is no
'less than 10 foot' connection to earth ground.
If your power supply is inferior, then why spend big bucks
on a UPS? An inferior supply may also damage other computer
components since essential functions are missing. Functions
that were defacto standard 30 years ago and specifically
demanded in Intel specs. Functions that a UPS does not even
provide, but are necessary for a computer. Before even
considering a UPS, one must first use an acceptable power
supply. That means either a brand name computer or the clone
assembler must have a long list of specification from the
power supply manufacturer. UPS cannot compensate for these
missing and essential power supply functions.
Obviously, this is still well beyond the OP's problem. Of
those five basic power problems - blackouts, brownouts, noise,
harmonics, and surges - the plug-in UPS really only claims to
address the first two. Yes, stepping up and down the
transformer does put less strain on the battery and does
provide supplementary voltage adjustments to a power supply.
Nice. But the OP must get basic, essential tools to first
provide basic facts - to get numbers to learn where his
failure is. When he provides facts, only then can we even
discuss power supply as reason for his problem. Procedures to
diagnosis his failure provided in an earlier post.

Yup.
I solved it (Sorry, I sent the 1st post from my wife's 'puter).
The disk was enabled with Microsoft 'logical partition' manager, so it wasn't seen properly by
fdisk, qtparted or any other linux tool I tried. I don't know why it was like that.
I repartitionned it, reformated the ntfs part in Windows and did the cfdisk on the rest.
Everything is fine. Except that I'm already out of space in /usr. Damn.
