• Can somebody please recommend a good local file backup utility that will be Windows & OSX Compatible?

  - by JAG2007

  I have an external hard drive that I keep all of my work files on and transfer them back and forth between my Windows 7 box at work, and my Mac at home (I work from home frequently). Can someone recommend a really good backup utility that I can use on that external drive, to back the files up to my work computer locally, or the other external drive on my machine at work? I'm looking for preferably a free or open source software, and I'd prefer it to be cross system compatible, although I would also consider using a software that will only work on the Windows box. Also, I will consider a software that has a price assuming it is a really good piece of software and the price is reasonable (like under $50 or so). I checked out CrashPlan a bit, but not sure if that's gonna be really what I'm looking for. To reiterate I'm not looking for online backup solutions, just a piece of software that can back up my data to another drive locally. CrashPlan Free seems to offer this, but not sure how good it is (considering their goal is to get me to buy a pay for version). *NOTE: I'm running Windows 7 in 64bit so I need a piece of software that will be compatible with 64bit OS. My previous software, PC Backup, is not. That's partly why I'm in this boat.

• HTTPS/HTTP redirects via .htaccess

  - by Winston

  I have a somehow complicated problem I am trying to solve. I've used the following .htaccess directive to enable some sort of Pretty URLs, and that worked fine. For example, http://myurl.com/shop would be redirected to http://myurl.com/index.php/shop, and that was well working (note that stuff such as myurl.com/css/mycss.css) does not get redirected: RewriteEngine on RewriteCond ${REQUEST_URI} !^(index\.php$) RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^/?(.*)$ index.php/$1 [L] But now, as I have introduced SSL to my webpage, I want the following behaviour: I basically want the above behaviour for all pages except admin.php and login.php. Requests to those two pages should be redirected to the HTTPS part, whereas all other requests should be processed as specified above. I have come up with the following .htaccess, but it does not work. h*tps://myurl.com/shop does not get redirected to h*tp://myurl.com/index.php/shop, and h*tp://myurl.com/admin.php does not get redirected to h*tps://myurl.com/admin.php. RewriteEngine on RewriteCond %{HTTPS} on RewriteCond %{REQUEST_URI} !^(admin\.php$|login\.php$) RewriteRule ^(.*)$ http://%{HTTP_HOST}/${REQUEST_URI} [R=301,L] RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^(admin\.php$|login\.php$) RewriteRule ^(.*)$ https://myurl.com/%{REQUEST_URI} [R=301,L] RewriteCond %{REQUEST_URI} !^(index\.php$) RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^/?(.*)$ index.php/$1 [L] I know it has something to do with rules overwriting each other, but I am not sure since my knowledge of Apache is quite limited. How could I fix this apparently not that difficult problem, and how could I make my .htaccess more compact and elegant? Help is very much appreciated, thank you!

• How can I store logs and meet compliance requirements for free?

  - by Martin

  I am trying to keep long-term logs of an app in such a way, that it could plausibly demonstrated to third parties/court that the application has processed certain data at a given time. The data can be represented in XML or text format. A simple gzipped log is not plausible, as I may have added or modified data afterwards, whereas an external logging service would be an overkill. Cost is an issue, we are not dealing with financial data or so, but rather some simple user generated content, where some malicious users tried to blame the operator in the past when things escalated and went to court. My question: Is there some kind of signing software for Linux that signs each element of a log in such a way, that it can be easily shown that no element can be added or modified afterwards? Plug-Ins into some free Splunk Alternatives would be fine too. Ideally the software I am looking for should be under a GPL or similar license. I could probably achive something like this by using PGP/GPG sgning functions and including the previous elements signituares within the following element, but I would prefer to use some program where you do not have to argue about the validity of your own code. Note to mods: I am not asking this question on Stackoverflow, because I am not looking for writing own code for reasons described above. I think this question rather fits into serverfault than superuser, as server-side logging software is discussed rather here than on superuser.

• RHEL 6 vs latest vanilla kernel differences?

  - by Yanko Hernández Álvarez

  What are the differences of the RHEL 6 kernel and the latest kernel.org one? I know RHEL is based on 2.6.32 with some features backported from newer kernels and that it also has other features that are not yet part of the latest vanilla kernel. Is there any comparison of the features of both kernels so I can tell how advanced is the RHEL kernel 6 vs. latest vanilla and vice versa?. It don't have to be the latest kernel at all, but the more recent the vanilla version, the better. What I want to know is: What features I lose/win if I change the RHEL kernel for the latest kernel.org’s one? What features are less matured/developed in the latest vanilla kernel than in RHEL’s (and vice versa)? (I guess KVM virtualization is one of them, but I'm not so sure.) What things (libraries / programs / etc) don’t interact as well with the latest vanilla kernel than with the RHEL’s one? In a related note: Is there ANY way to be as up to date (kernelwise) as possible (using RHEL 6) without loosing too much in the process? (Any way except doing the patching myself, I don’t have the necessary expertise) Any repo I don’t know of? Any alternative? Update: The srpm doesn't include patches (see comments), so that way is not possible. Clarification: I'm interested in how "old" the RHEL kernel gets as time goes by, and to know when the latest upstream kernel includes all the improvements included in the RHEL version.

• SUSE Linux and Xen on Mac Pro - How best to prepare and configure?

  - by Andrew J. Brehm

  This is a longwinded question, so bear with me please. I have a 2009 Mac Pro with two CPUs and 8 GB of memory which is totally overpowered for Mac OS X. I am also in the process of slowly moving away from Mac OS X as my main platform. Since the Mac Pro is really new and nice I have finally decided to use it for another platform. I am familiar with Linux and SUSE Linux. Ultimately I want to run some version of SUSE Linux (recommend one, doesn't have to be free as in no money) and Xen. Here are the individual questions: Which version of SUSE Linux should I use and how do I install it on a Mac Pro? Note that the distribution must come with usable Xen. I am willing to pay. I assume Xen will work on my computer (it has VT support etc.). Is my assumption correct? I want to run Windows 7 and another instance of SUSE Linux under Xen. Is it possible to run Mac OS X Server under Xen (on a Mac Pro)? Which email client under Linux supports imap is is best-suited for integrating with MobileMe? Does SUSE Linux support the ATI Radeon HD 4870 and the Apple Cinema Display 1920 x 1200 resolution? What else should I take into account?

• Apache: redirect to https before AUTH for server-status

  - by Putnik

  I want to force https and basic auth for server-status output (mod_status). If I enable auth and user asks for http://site/server-status apache first asks for pass, then redirects to httpS, then asks for pass again. This question is similar to Apache - Redirect to https before AUTH and force https with apache before .htpasswd but I cannot get it work because we are speaking not about generic folder but Location structure. My config (shortly) is as follows: <Location /server-status> SSLRequireSSL <IfModule mod_rewrite.c> RewriteEngine on RewriteBase /server-status RewriteCond %{HTTPS} off RewriteCond %{SERVER_PORT} 80 RewriteRule ^ - [E=nossl] RewriteRule (.*) https://site/server-status} [R=301,L] </IfModule> SetHandler server-status Order deny,allow Deny from all Allow from localhost ip6-localhost Allow from 1.2.3.0/24 Allow from env=nossl AuthUserFile /etc/httpd/status-htpasswd AuthName "Password protected" AuthType Basic Require valid-user Satisfy any </Location> I assume Allow from env=nossl should allow everyone with RewriteCond %{HTTPS} off and server port 80, then force it to redirect but it does not work. Please note, I do not want force to SSL the whole site but /server-status only. If it matters the server has several sites. What am I doing wrong? Thank you.

• How to set up RAID-0 first time on new PC?

  - by jasondavis

  I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

• Certificates required for WHQL-certified drivers

  - by Kasius

  The 64-bit Windows 7 image that we deploy to machines at our site does not contain all of the certificates included on a default Windows image. Automatic root certificate installation is also disabled per policy from higher in the organization. We have had a lot of trouble installing many WHQL-certified drivers from reputable companies (ex. HP, Lexmark, Dell, etc.), and I hypothesize that a required certificate is missing from one of the certificate stores on the machine. The error we typically get is: The driver cannot be installed because it is either not digitally signed or not signed in the appropriate manner. I know that it is signed. A .CAT file is included, and it has the following tree from top to bottom: Microsoft Root Authority (thumbprint a4 34 89 15 9a 52 0f 0d 93 d0 32 cc af 37 e7 fe 20 a8 b4 19) Microsoft Windows Hardware Compatibility PCA (thumbprint 93 b8 d8 82 0a 32 db 20 a5 ea b6 8d 86 ad 67 8e fa 14 ea 41) Microsoft Windows Hardware Compatibility Publisher (thumprint b0 50 45 45 42 4e be 2c 16 2f 62 5b bf 5a e6 9b 96 bf 0b 0b) What certificates are required to install WHQL-certified drivers? Is it possibly something other than certificates? Thanks! NOTE: I have posted this question on Technet as well, but honestly, I've never had a lot of luck posting questions on the Technet forums.

• Howto change Axis server-config.wsdd so that we don't expect a SOAPAction

  - by GKForcare

  The problem I'm facing is that the client of my service will never send me a SOAPAction header. How can I tell Axis to still map to the incomming call to my service implementation anyway. I did bump into tricks like adding a Handler like this: <handler name="ReportMapper" type="java:com.mycompany.project.ReportMapper"/> <transport name="http"> <requestFlow> <handler type="ReportMapper"/> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> <parameter name="qs:list" value="org.apache.axis.transport.http.QSListHandler"/> <parameter name="qs:wsdl" value="org.apache.axis.transport.http.QSWSDLHandler"/> <parameter name="qs.list" value="org.apache.axis.transport.http.QSListHandler"/> <parameter name="qs.method" value="org.apache.axis.transport.http.QSMethodHandler"/> <parameter name="qs:method" value="org.apache.axis.transport.http.QSMethodHandler"/> <parameter name="qs.wsdl" value="org.apache.axis.transport.http.QSWSDLHandler"/> </transport> but that did not help. The mapper is found during the creation of the WSDL but when calling the service, the invoke of the handler is not used. I do need to note that when I simulate the SOAP-call using @curl@ and I do add the SOAPAction header, the invoke is called. Any help would be most appreciated.

• How can I write directly to my Zune HD hard drive?

  - by iamgoat

  When syncing photos to the Zune HD it resizes them down to a much lower resolution which means I cannot load a high res picture on it (comic book) and zoom in to read it. This defeats the whole purpose of having a zoom feature. There is a registry hack you can make to get the Zune to display under My Computer. Then if you killed the zune process while it's syncing you'd be able to access it like a hard drive and copy files to it. It seems like the more recent firmware and/or Zune software version now prevents this. How can I treat it like an HDD and copy files to it? I simply want to take my original pictures folder and copy it over the low resolution versions the Zune software resized it to. An alternative option would be to remove the hard drive from it and see if I can connect it to a computer directly, but I just got this and don't want to disassemble it yet. Note to Microsoft: Why do you allow me to set the encoding quality of music, but not photos?

• Windows 7 Automatically Connecting To Unsecured Wireless Networks On Startup

  - by Xtend

  Most of the questions on this topic related to folks connecting to somebody else's wireless network when their own was available and could remedy the situation by going to their connections and unchecking the "connect automatically" box. See this: " Avoid automatically connecting to wireless network on windows 7 " as an example. In my situation, I've noticed that Win 7 will automatically connect to any unsecured wifi network - even if I have never connected to it in the past. If I am traveling and boot Win 7, it will start and connect to what appears to be the best signaled unsecured network without prompting me for confirmation (note: in the above link, "Naveen" seems to have same problem). Obviously, that is a security concern to me. Further, when I open "Network and Sharing" and "Manage wireless networks" the network is not displayed (probably because I labelled it a public network). Again, these are new, never connected with before, wireless networks. I always promptly disconnect from them but don't want to have to be on constant guard for an auto connection to a malicious network. This began about a month ago, as I recall, Win 7 did not behave like this in the past, I didn't monkey with wifi settings, and don't use a 3rd party connection manager. I did have to download some internet security certificates for army website access but I don't think that should mess with network settings. Any ideas how I can tell Win7 cease automatically connecting to networks or, at least, to prompt me for a confirmation before connecting?

• KVM Hosting: How to efficiently replicate guests

  - by javano

  I have three KVM servers each with 1 guest VM, running directly on it's local storage, (so they are essentially getting a dedicated box worth of computing power each). In the event of a host failure I would like the guests replicated to at least one of the other hosts so I can spin it up there, until the failing host is fixed. I am curious about KVM cloning. I can clone a VM live or when it's suspended/shutdown. Obivously suspended VMs will naturally be quicker to clone but these three VMs comprise three parts of a single solution, so I don't want to ever have any one of them shutdown. How can I efficiently clone these VMs between servers? I have had a couple of ideas, but are these insane or, is there a better method I have missed for my scenario? Set up a DRDB partition between box 1 and 2 where VM 1 runs from, and so is replicated between box1 and box 2, repeat between box 2 & 3, and box 3 & 1 (This could be insane, I have never used DRDB only read about it) Just use standard KVM CLI clone options to perform live clones (I'm dubious about this because I don't know how long it will take and what the performance impact will be during) Run a copy of each VM on at least one other host, and have the guest on one host export it's data to the matching guest on another host where it can import that data, scripting this on the guest) Some of other way? Ideas welcome! Side Note These servers have 4x15k SAS drives in a RAID 10 so they aren't rocketing fast, and as I mentioned, each VM runs from the host's local storage, no NAS or SAN etc. So that is why I am asking this question about guest replication. Also, this isn't about disaster recovery. Guests will be exporting their data to a NAS over a VPN, so I am looking at how I can have them quickly spun up in a host failure situation.

• Steps to deploy a custom routing protocol

  - by user134589

  I'm a Ph.D Student and I'm researching a Service Centric Networking architecture with resourceallocation on a large scale. What I'm looking to do is expand an existing routing protocol like OSPF with extra fields and some new message types that I need for communication between Nodes. I want to manipulate the cost of a network link and I want paths to be calculated like in OSPF V2/v3, but using the cost that my algorithms have calculated. What I have I have the source code of OSPF from Quagga. I am assuming I can edit this code how I want, including packet structures and creating new types. Yes, I am aware it won't be easy but this is a 6 years research project and I am eager to develop something new, to move forward. What I need I would like to know how I can deploy the edited OSPF source files I have (written in C) on any type of server. I have a large testbed environment available with hundreds of virtual nodes and pretty much any OS out there. So if I want to test my extended protocol, how do I make all the nodes in a network use this to communicate? I do not understand what parts of the kernel I need to edit here. I tried searching for days now and I am unable to find how to deploy a non-existing routing protocol, without the use of an application-level framework. If somebody could push me in the right direction that'd be awesome. note: I need this to be a routingprotocol and not an application, since I want this to work on op of the network layer for performance reasons. Thanks!

• Sending mail results in "Sender address rejected: Domain not found"

  - by user1281413

  The setup: WHM/CPanel CentOS 5 server running Exim and Courier for mail services, and BIND for domain name services. I recently moved servers. The old server was running a HIGHLY similar configuration, and all accounts were ported via WHM. However, the server is unable to send, and sometimes receive email. Errors I am seeing (when I do get an error mail back) state: 450 4.1.8 : Sender address rejected: Domain not found Edit for clarity: this is the error response from remote mail servers. Numerous independent mail servers come back with the same error. (Email address is merely one valid example) My first instinct of course was to check the domain records. However, k-t.org appears to have a valid record (including an MX record), even after running it through domain checks on a completely different server elsewhere and online. Note that the issue appears to happen with all the domains hosted on the server, not just k-t.org I have also ensured that a PTR was created. My Googling has only lead me to people who had fairly basic DNS mistakes, but either I'm blind/dumb (possible, DNS is not my strong suite), or it's something that is a bit more archaic. I've run out of ideas, and I can't seem to find anything that could explain why servers are unable to resolve the domains. There doesn't seem to be anything missing or incorrect.

• Boot sequence unlike reboot

  - by samgoody

  When I turn on the computer it acts very differently than when I reboot it. [WinXP Pro, Intel Core2 6600, 2.4GHZ, 2GB RAM, NVIDA GeForce] Boot: Monitor must be plugged into the motherboard or no image. Screen resolution 800x600. Changes to the resolution cause only the top half of the screen to be usable, and are lost when I shut down the computer. Desktop icons arranged in neat rows on left of desktop. Nothing of note in system tray In Device Manger - Display adapter: Intel(R) Q965/Q963 Express Chipset Family In Device Manger - Monitors, two monitors are listed Hibernate and standby work. Reboot: Monitor must be plugged into the graphics card or no image. Screen resolution - 1280x1024 Desktop icons arranged in the cute circle that I put them in. NVIDIA icon shows in system tray. In Device Manger - Display adapter: NVIDA GeForce 6200LE In Device Manger - Monitors, one monitor is listed Hibernate and standby do not work. When awakened after a hibernation it says: The system could not be restarted from its previous location because the restoration image is corrupt. Delete restoration data & proceed to system boot? Double reboot (inconsistent): Monitor must be plugged into the graphics card. Screen resolution - 1024x768 Odd icon shows in system tray whose tooltip says "Intel Graphics" For a while my morning ritual was to boot, wait, reboot using (alt+ctrl+del - ctrl+u - R), wait. Keeping the monitor plugged into the graphics card. But aside for the inefficiency of this method, I sometimes want to standby and can't. On the other hand, the computer is unusable when set to 800x600. Please help, anyone?

• Finding matching columns in excel

  - by fakaff

  I've never used excel before so I need the simplest solution available, and this is a work assignment due this week so I didn't have time read much of the documentation. Basically, I have two tables, A and B, and they are both thousands of rows long. Description of my task: right now (since I don't know better) I'm manually doing this: Go to row i in table B. Select entries in columns B(a, b, c) of that same row. Look for a row in table A where column A(b) matches row B(a). Paste the entries of columns B(a) of row i at the end of the row found in the last step. Repeat for row i + 1. Example: row B(cat, dog, mouse) matches A(mammal, cat, Mr. Whiskers). So I would paste B after A and have A(mammal, cat, Mr. Whiskers, cat, dog, mouse). Note: I am not joining tables. I am merely extending table A by pasting row A(b) if row A(b) matches row B(a). Also, sometimes entries are spelled slightly differently. Using wildcards to search for candidates would be of help. As the description should let on, this task is very tedious and inefficient if I don't know how to automate some operations (there are thousands of entries). Any quick tips as to how to be more productive is a big help.

• Hyper-V vss-writer not making current copies

  - by Martinnj

  I'm using diskshadow to backup live Hyper-V machines on a Windows 2008 server. The backup consists of 3 scripts, the first will create the shadow copies and expose them, the second uses robocopy to copy them to a remote location and the third unexposes the shadow copies again. The first script – the one that runs correctly but fails to do what it's supposed to: # DiskShadow script file to backup VM from a Hyper-V host # First, delete any shadow copies of the drives. System Drives needs to be included. Delete Shadows volume C: Delete Shadows volume D: Delete Shadows volume E: #Ensure that shadow copies will persist after DiskShadow has run set context persistent # make sure the path already exists set verbose on begin backup add volume D: alias VirtualDisk add volume C: alias SystemDrive # verify the "Microsoft Hyper-V VSS Writer" writer will be included in the snapshot # NOTE: The writer GUID is exclusive for this install/machine, must be changed on other machines! writer verify {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} create end backup # Backup is exposed as drive X: make sure your drive letter X is not in use Expose %VirtualDisk% X: Exit The next is just a robocopy and then an unexpose. Now, when I run the above script, I get no errors from it, except that the "BITS" writer has been excluded because none of its components are included. That's okay because I really only need the Hyper-V writer. Also I double checked the GUID for the writer, it's correct. During the time when the Hyper-V writer becomes active, 2 things will happen on the guest machines: The Debian/Linux machine will go to a saved state and restore when done, all fine. The Windows guests will "creating vss snapshop-sets" or something similar. Then X: gets exposed and I can copy the .vhd files over. The problem is, for some reason, the VHD files I get over seems to be old copies, they miss files, users and updates that are on the actual machines. I also tried putting the machines in a saved sate manually, didn't change the outcome. I hope someone here has an idea of how to solve this.

• Server Recovery from Denial of Service

  - by JMC

  I'm looking at a server that might be misconfigured to handle Denial of Service. The database was knocked offline after the attack, and was unable to restart itself after it failed to restart when the attack subsided. Details of the Attack: The Attacker either intentionally or unintentionally sent 1000's of search queries using the applications search query url within a couple of seconds.

• How to show "only number" in picture cross-reference in Word 2007 document?

  - by kornelijepetak

  I have many pictures in a document and I reference them very often in text. I don't want to lose the order so I am using Insert - Cross-reference. This opens the cross-reference dialog where I can set Reference type to Picture. For "Insert reference to", there are 5 choices: - Entire caption - Only label and number - Only caption text - Page number - Above/below What I need is a reference that would be inserted like this: [4], and not like this: [Picture 4]; None of these options enable me to do it. Is there any way to make Word 2007 insert a reference to only Caption Number? Note: The document is written in Croatian language which has 7 declension cases, so using "Picture 4" would not be valid in all cases. Actually caption label Picture is set to croatian word "Slika" and when I need to say say "in the picture" I can't because it would be "na Slici 5." and not "na Slika 5." (like Word would make me do). That's why I need to reference only the caption number. Is that possible in Word 2007?

• Calling Excel from PHP 5 through COM fails on Windows 7 when Apache started through Task Planner

  - by Stefan Pantke

  I currently write an application, which controls Excel through COM: The app creates a COM-based Excel instance, opens some XLS files and reads their contents. Scenario I On Windows 7, I start Apache and mySQL using xmapp-control with system administrator rights. All works as expected. The PHP-based controller script interacts with Excel as expected. Scenario II A problem appears, if I start Apache and mySQL as 'background jobs'. Here is how: I created two jobs using Windows 7 Task Planner. One runs apache_start.bat, the other runs mysql_start.bat. Both tasks run as SYSTEM with elevated privileges when Windows 7 boots. Apache and mySQL work as expected. Specifically, Apache serves HTTP request from clients and PHP is able to talk to mySQL. When I call the PHP controller, which calls and interacts with Excel using COM, I do receive an error. The error seems to come from Excel [not COM itself] and reads like this: Excel can't read the XLS-file Excel failed to save the file due to an ill-name worksheet Interestingly, during the first run of the PHP-based controller script, it takes a few seconds to render the error message. Each subsequent run immediately renders the error message. Windows system logs didn't show a single problem report entry. Note, that the PHP program and the Apache instance didn't change - except the way Apache was started. At least the PHP controller script is perfectly able to read the file-system, since it provides the pathes to the XLS-file through scandir() of a certain directory. Concurrency issues can't be the cause of the problem. A single instance of the specific PHP controller interacts with Excel. Question Could someone provide details, why this happens?

• What's the piece of hardware listening on Facebook's or Wikipedia's IP address?

  - by Igor Ostrovsky

  I am trying to understand how massive sites like Facebook or Wikipedia work, for my intellectual curiosity. I read about various techniques for building scalable sites, but I am still puzzled about one particular detail. The part that confuses me is that ultimately, the DNS will map the entire domain to a single IP address, or a handful of IP addresses in the case of round-robin DNS. For example, wikipedia.org has only one type-A DNS record. So, people from all over the world visiting Wikipedia have to send a request to the one IP address specified in DNS. What is the piece of hardware that listens on the IP address for a massive site, and how can it possibly handle all the load coming from the requests for users all over the world? Edit 1: Thanks for all the responses! Anycast seems like a feasible answer... Does anyone know of a way to check whether a particular IP address is anycast-routed, so that I could verify that this really is the trick used in practice by large sites? Edit 2: After more reading on the topic, it appears that anycast is not typically used for dynamic web content. Anycast is usually used for UDP (e.g., DNS lookups), or sometimes for static content. One interesting thing to note is that Facebook uses profile.ak.fbcdn.net to host static content like style sheets and javascript libraries. Each time I ping this name, I get a response from a different IP address. However, I can't tell whether this is anycast in action, or a completely different technique. Back to my original question: as far as I can tell, even a large site will have a single expensive piece of load-balancing hardware listening on its handful of public IP addresses.

• NTFS 'Owner' missing when accessing hard disk from external USB adapter

  - by trismarck

  I have a hard drive with Windows XP SP3 installed on it. When the drive is connected through the standard SATA connector inside the laptop, everything works as expected. However when I remove the drive from the laptop and connect the drive to the external USB adapter, almost all files / folders lose the 'Owner' field contents. I was wondering why could that be. I've tried two USB adapters and this happens on each. I could take the ownership of all of the files, but this would overwrite the Owner value (the Owner value that is present when the drive is accessed through standard SATA connector in the laptop). //edit: if the hard drive is used through the USB adapter, I can't access most of the files, at least until I take ownership of the files (/folders). This is how it looks like: HDD inside USB adapter: HDD inside laptop: (note the Owner column) //edit: some of the files on the first screenshot have Owner field filled up. That's because I took the ownership of those files / folders to be able to access the files on the hard drive. //edit2: also, if the hard drive is connected through USB adapter and if I've took the ownership of some files by the 'ddd' user, then if i login as a different user (lets say 'eee' user), the owner field is _still_ empty: ddd user: eee user: eee user can't access the 'ddd' folder. Both users have Administrator priviledges.

• MySQL slave server from dumps

  - by HTF

  I've created a slave server from live machine which is acting as a master now. I use the following procedure to create it: mysqldump --opt -Q -B --master-data=2 --all-databases > dump.sql then I imported this dump on the new machine, applied the "CHANGE MASTER TO..." directive with a log file/position from the dump. Please note that I have around 8000 databases and I didn't stop the master while the dumps were running. The replication works fine but is this a properly method for creating a slave server? I'm planning to promote this slave to a master (different location) so I would like to make sure that there is a 100% data consistency between the servers. I've found this article where it says: The naive approach is just to use mysqldump to export a copy of the master and load it on the slave server. This works if you only have one database. With multiple database, you'll end up with inconsistent data. Mysqldump will dump data from each database on the server in a different transaction. That means that your export will have data from a different point in time for each database. Thank you

• Linux Live CD only works when Windows is in Legacy mode?

  - by Vee

  I have asked a similar question before and no one was able to help me but I think it was because I wasn't phrasing it properly. This is a better restatement of the question. I have Windows 8 and Linux Mint dual booted on my pc. When I tried to boot the Linux from a CD ROM only, it would give me the following error: error: failure reading sector 0x0 from 'hd1' error: you need to load the kernel first. Press any key to continue... The Linux Mint works fine but otherwise, but it gives this error when I try to boot from CD. The boot Linux from CD only worked when I changed the Windows to Legacy mode in the BIOS settings. When I changed it back to UEFI, it would give the same error. Why is this? How can I fix it? I am somewhat new so is there anything else I should know about all of this? NOTE: I changed the Linux into UEFI mode using boot-repair but that still did not solve the problem when I tried to boot from CD ROM.

• iptables configuration under ubuntu

  - by aioobe

  I'm following a tutorial on setting up a dns-tunnel. I've run into the following instruction: Now you need to enable forwarding on this server. I use iptables to implement masquerading. There are many HOWTOs about this (a simple one, for example). On Debian, the configuration file for iptables is in /var/lib/iptables/active. The relevant bit is: *nat :PREROUTING ACCEPT [6:1596] :POSTROUTING ACCEPT [1:76] :OUTPUT ACCEPT [1:76] -A POSTROUTING -s 10.0.0.0/8 -j MASQUERADE COMMIT Restart iptables: /etc/init.d/iptables restart The problem is that I don't have any /var/lib/iptables/active. (I'm on ubuntu.) How can I accomplish this? I suspect that I should just interact with the iptables command somehow but I have no clue what to write. Best would probably be if I could put the commands in a script somehow I suppose. (A side-note. If I execute a few iptables-commands it wont be there for ever, right? The rules will be discarded on reboot?)
