| Secure Unix permissions for an Apache website developer Posted: 19 Apr 2004 09:26 AM PDT James Schnack wrote: .. 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. WWJD? JWRTFM Rot13 for email address: yvfgf @ ehqa.pbz |

Same thing as to My Linux machine says that the it can't find the ppp make sure that it is installed. but I do see it in the root/etc area and the ppp0 is when you make your network. under drake config you will find something dealing with ppp0 ppp1 etc. but according to my Linux it could not find the ppp daemon. |
| 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. Jean-David Beyer wrote: |

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.
