  • Apache cyclic redirection problem

    - by slicedlime
    I have an extremely weird problem with one of my sites. I run a number of blogs off a single apache2 server with a shared wordpress install. Each site has a www.domain.com main domain, but a ServerAlias of domain.com. This works fine for all the blogs except one, which instead of redirecting to www.domain.com redirects to domain.com, causing a cyclic redirection. The configuration for each host looks like this: <VirtualHost *:80> ServerName www.domain.com ServerAlias domain.com DocumentRoot "/home/www/www.domain.com" <Directory "/home/www/www.domain.com"> Options MultiViews Indexes Includes FollowSymLinks ExecCGI AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> As this didn't work, I tried a mod_rewrite rule for it, which still didn't redirect correctly. The weird thing here is that if i rewrite it to redirect to any other domain it will redirect correctly, even to another subdomain. So a rewrite rule for domain.com that redirects to foo.domain.com works, but not to www.domain.com. In the same way, trying to redirec to www.domain.com/foo/ ends me up with a redirection to domain.com/foo/. Even weirder, I tried setting up domain.com as a completely separate virtual host, and ran this php test script as index.php on it: <?php header('Location: http://www.domain.com/' . $_SERVER["request_uri"]); ?> Hitting domain.com still redirects to domain.com! Checking out the headers sent to the server verifies that I get exactly the redirect URL I wanted, except with the "www." stripped. The same script works like a charm if I replace www. with foo or redirect to any other domain. This has now foiled me for a long time. I've diffed the vhosts configs for a working domain and the faulty one, and the only difference is the domain name itself. I've diffed the .htaccess files for both sites, and the only difference is a path related to the sharing of wordpress installation for the blogs: php_value include_path ".:/home/www/www.domain.com/local/:/home/www/www.domain.com/" I searched through everything in /etc (including apache conf) for the domain name of the faulty host and found nothing weird, searched through everything in /etc for one of the working ones to make sure it didn't differ, I even went so far to check on the DNS setup of two domains to make sure there wasn't anything strange going on. Here's the response for the faulty one: user@localhost dir $ wget -S domain.com --2010-03-20 21:47:24-- http://domain.com/ Resolving domain.com... x.x.x.x Connecting to domain.com|x.x.x.x|:80... connected.

I've had this problem for a long time, and I feel like I've tried everything. I can't see why the different domains would act differently under the same installation with the same settings. Help :(

  • rdiff-backup is taking longer and longer every time it runs

    - by Jakobud
    I've been running rdiff-backup for the past week or so, every night at 4am. It started out not taking that long, but its taking longer and longer and longer every time its runs every night. In some cases there are quite a few new and changed files and in other cases, not so much. It started out taking < 10 minutes, and after a week its taking over 4.5 hrs to run.

  • Raid 1 array won't assemble after power outage. How do I fix this ext4 mirror?

    - by Forkrul Assail
    Two ext4 drives on Raid 1 with mdadm won't reassemble after the power went out for an extended period (UPS drained). After turning the machine back on, mdadm said that the array was degraded, after which it took about 2 days for a full resync, which completed without problems. On trying to remount the array I get: mount: you must specify the filesystem type cat /etc/fstab lines relevant to setup: /dev/md127 /media/mediapool ext4 defaults 0 0 dmesg | tail (on trying to mount) says: [ 1050.818782] EXT3-fs (md127): error: can't find ext3 filesystem on dev md127.

Could someone explain why it would resync after the powerout, only to seemingly nuke the drive? Thanks for reading. Any help much appreciated. I've tried everything I can think of, including booting and filesystem checking with SystemRescue and Ubuntu liveboot discs.

  • What would cause an .exe to vanish without a trace?

    - by Peter pete
    I have a few computers. One computer, at home, one day suddenly had its pgbouncer.exe vanish. The antivirus didn't have it in its virus chest [avast]. I couldn't find the bgbouncer anywhere. All the other pgbouncer files remained where they used to be, except the exe had vanished. I hadn't uninstalled it, nor had anyone else used the machine. I hadn't installed any new software since the previous time I had used it either. Just now, however, my TV computer was running out of disk space, which was weird because I had python setup to do transcoding and archiving. I logged in and voila! python.exe had vanished !! Once again, Avast.exe didn't have it in its virus chest, and dunno! I do this time, with the TV computer, know exactly the date that python vanished. Sat the 18th my python scripts ran fine. Sat the 19th python was gone. I'm going to do some hunting in the event log to see what happened that day. But if anyone has experienced vanishings before and has a clue what happened, I would like to know. FYI: Both computers (bgbouncer vanish and python vanish) were running Win7 with the RDP hack and both on SSDs and both with Avast. Both computers had all windows updates set to manual(to prevent random stuff changing!) and neither had recently had any windows updates manually applied. FYI2: Tv computer had since the beginning of October dropbox running all the time trying to download two files. Sadly, a temporary download of each of these two files by dropbox resulted in Avast freaking out and virus-chesting them, and then dropbox downloading them partially again, before being dropboxed. Now, these two files were binaries from a program I had personally written and were clean on other machines. Since the python vanishing I have deleted these two binaries from dropbox (using the website) and dropbox exe on the tv computer is now at peace. I don't think this should cause python.exe to vanish though :/ New edit: On the 18/10/2013, at 0742 my python script ended with an error: "file still in use" which was unexpected but I shrugged it off since sometimes media portal doesn't release the recording. But on second thoughts is weird since the show in use would have been finished recording the day before. On the 18/10/2013 at 0807 the windows event log complains that several drivers required for CutePDF, send to onenote 2010, send to onenote 2013, microsoft xps document writer aren't installed. I just checked now and indeed those printers have vanished! New update! I found my python.exe that had been removed. It was still in the C:\Python33\ directory except it had been renamed to a random string charater.tmp (ie, it was made into a temp file) with a creation date of 19/10/2013 at 0600:02 am. Now, the computer normally wakes at 6am to do transcoding. What could have moved my python file into a tmp file?

  • Netbeans Profile JUnit 4 problem

  • Graph search problem with route restrictions

    - by Darcara
    I want to calculate the most profitable route and I think this is a type of traveling salesman problem. I have a set of nodes that I can visit and a function to calculate cost for traveling between nodes and points for reaching the nodes. The goal is to reach a fixed known score while minimizing the cost. This cost and rewards are not fixed and depend on the nodes visited before. The starting node is fixed. There are some restrictions on how nodes can be visited. Some simplified examples include: Node B can only be visited after A After node C has been visited, D or E can be visited. Visiting at least one is required, visiting both is permissible. Z can only be visited after at least 5 other nodes have been visited Once 50 nodes have been visited, the nodes A-M will no longer reward points Certain nodes can (and probably must) be visited multiple times Currently I can think of only two ways to solve this: a) Genetic Algorithms, with the fitness function calculating the cost/benefit of the generated route b) Dijkstra search through the graph, since the starting node is fixed, although the large number of nodes will probably make that not feasible memory wise. Are there any other ways to determine the best route through the graph? It doesn't need to be perfect, an approximated path is perfectly fine, as long as it's error acceptable. Would TSP-solvers be an option here?

  • printSoln module problem

    - by dingo_d
    Hi I found in book:Numerical Methods in engineering with Python the module run_kut5, but for that module I need module printSoln, all provided in the book. Now I cp the code, made necessary line adjustments and so. The code looks like: # -*- coding: cp1250 -*- ## module printSoln ''' printSoln(X,Y,freq). Prints X and Y returned from the differential equation solvers using printput frequency ’freq’. freq = n prints every nth step. freq = 0 prints initial and final values only. ''' def printSoln(X,Y,freq): def printHead(n): print "\n x ", for i in range (n): print " y[",i,"] ", print def printLine(x,y,n): print "%13.4e"% x,f for i in range (n): print "%13.4e"% y[i], print m = len(Y) try: n = len(Y[0]) except TypeError: n = 1 if freq == 0: freq = m printHead(n) for i in range(0,m,freq): printLine(X[i],Y[i],n) if i != m - 1: printLine(X[m - 1],Y[m - 1],n) Now, when I run the program it says: line 24, in <module> m = len(Y) NameError: name 'Y' is not defined But I cp'd from the book :\ So now when I call the run_kut module I get the same error, no Y defined in printSoln... I'm trying to figure this out but I suck :( Help, please...

  • Meraki wireless access point disconnects clients

    - by resolver101
    We have a Meraki MR16 Cloud Managed AP and it disconnects certain clients. The clients with Intel wireless cards work without any disconnects. The Meraki reports the follow in its event log: Sep 4 09:55:47 WPA authentication Sep 4 09:55:47 802.11 association channel: 11, rssi: 64 Sep 4 09:55:38 802.11 disassociation client has left AP Sep 4 09:55:38 WPA deauthentication vap: 0, radio: 0, aid: 1633956416 An example wireless network card which the Meraki disconnects is Realtek RTL8191SE 802.11b/g/n WiFi Adapter. The realtek laptop is sat 2 meters away from the AP and has a lot of signal and the Meraki reports minimal interference. Any ideas why it disconnects non-intel wireless network cards?

  • Troubleshooting Windows Authentication problems (no challenge) in IIS 7.5?

    - by Aaronaught
    I know that there are thousands of reports of people having trouble getting Integrated Windows Authentication to work with IIS, but they all seem to lead to web pages that don't apply or solutions that I've already tried. I've deployed dozens of sites like this before, so either there's something bizarre going on with the server/configuration, or I've been looking at this too long and not seeing the obvious. Simply put, everything works perfectly on my local machine, but falls apart on the production server, which as far as I can tell has the exact same configuration. On the local machine: The machine is running Windows 7 Ultimate, Service Pack 1, IIS 7.5. The site has been tested successfully, using both IIS and the VS Web Development Server. The IIS site config has all authentication methods disabled except Windows Authentication. The local machine is not on any domain. The Providers set up are Negotiate and NTLM (not Negotiate:Kerberos). Extended Protection is Off. All browsers tested (IE, Firefox, Chrome) show the challenge prompt and allow me to log in to the localhost domain with my (local) Windows account. All browsers tested also work using an opaque local IP address - so the browsers themselves don't seem to care whether the site appears "local" or "remote". I've added a display line to the web page which shows the currently-logged-in user and it shows exactly what I would expect (whichever local user I logged in with). On the remote machine: The server is running Windows Server 2008 R2, IIS 7.5. Loading the web page results in an immediate 401.2 error: You are not authorized to view this page due to invalid authentication headers. No challenge prompt ever appears. The IIS site config has all authentication methods disabled except Windows Authentication. The remote machine is not on any domain. The Providers set up are Negotiate and NTLM (not Negotiate:Kerberos). Extended Protection is Off. On the remote machine (remote desktop session), the same error appears in Internet Explorer regardless of whether the domain is localhost or the external IP address. If I try to view the remote web site from my local machine, the error is still 401, but a slightly different 401. No subcode, with the text: Access is denied due to invalid credentials. The Windows Authentication IIS role feature is installed. The WindowsAuthentication Module is added (at the Server level). The exact same error occurs if I turn off Windows Authentication and enable Basic Authentication. The site does load if I turn off Windows Authentication and enable Anonymous (obviously). I've already followed all of the troubleshooting steps on Microsoft Support: Troubleshooting HTTP 401 errors in IIS I've already tried the workaround shown on another Microsoft support page (supposedly to force NTLM as the only method). Last but not least, I tried turning on FREB for 401.2 errors and the results don't seem to tell me anything useful, all I see is the following warning: MODULE_SET_RESPONSE_ERROR_STATUS ModuleName IIS Web Core Notification 2 HttpStatus 401 HttpReason Unauthorized HttpSubStatus 2 ErrorCode 2147942405 ConfigExceptionInfo Notification AUTHENTICATE_REQUEST ErrorCode Access is denied. (0x80070005) ...this seems to just be telling me what I already know (that it's simply rejecting the request instead of negotiating the credentials). The trace does indicate that the WindowsAuthentication module is correctly loaded because there is a NOTIFY_MODULE_START line with ModuleName = WindowsAuthentication (and various other ASP.NET follow-up events - [un]fortunately, no interesting errors or warnings here). Can anyone tell me what I might be missing here? Quick Update: I'm a little uncomfortable sending a whole Wireshark dump as it would reveal IPs, URLs and other stuff, but I did a side-by-side comparison of the HTTP responses from localhost and the remote server in Fiddler, and it seems fairly self-evident what the problem is: Localhost: HTTP/1.1 401 Unauthorized Cache-Control: private Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM X-Powered-By: ASP.NET Date: Sat, 17 Dec 2011 23:42:34 GMT Content-Length: 6399 Proxy-Support: Session-Based-Authentication Remote: HTTP/1.1 401 Unauthorized Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Sat, 17 Dec 2011 23:43:13 GMT Content-Length: 1293 Aside from a few seemingly-inconsequential differences like cache-control, the main difference is that the remote server is not sending the WWW-Authenticate headers back to the client. So, I guess that narrows the question down to: Why is IIS not sending WWW-Authenticate headers when Windows Authentication appears to be installed, loaded, and exclusively enabled?

  • SQL Cluster on Hyper V Failover Cluster

    - by Chris W
    We have a VM running SQL Server on a 6 node cluster of blades. The VM's data files are stored a SAN attached using a direct iSCSI connection. As this SQL server will be running a number of important databases we're debating whether we should be clustering the SQL Server or will the fact that the VM is running in the cluster itself sufficient to give us high availability. I'm used to running SQL clusters when dealing with physical servers but I'm a bit sketchy on what is best practice when all the servers are just VMs sat on Hyper V. If a blade running the VM fails I presume the VM will be started up on another load. I'm guessing the only benefit that adding a SQL cluster to the setup will give us it that the recovery time after a failure will be a little quicker? Are there any other benefits?

  • AJI Report #19 | Scott K Davis and his son Tommy on Gamification and Programming for Kids

    - by Jeff Julian
    We are very excited about this show. John and Jeff sat down with Scott Davis and his son Tommy to talk about Gamification and Programming for Kids. Tommy is nine years old and the Iowa Code Camp was his second time presenting. Scott and Tommy introduce a package called Scratch that was developed by MIT to teach kids about logic and interacting with programming using sprites. Tommy's favorite experience with programming right now is Lego Mindstorms because of the interaction with the Legos and the development. Most adults when they get started with development also got started with interacting more with the physical machines. The next generation is given amazing tools, but the tools tend to be sealed and the physical interaction is not there. With some of these alternative hobby platforms like Legos, Arduino, and .NET Micro Framework, kids can write some amazing application and see their code work with physical movement and interaction with devices and sensors. In the second half of this podcast, Scott talks about how companies can us Gamification to prompt employees to interact with software and processes in the organization. We see gamification throughout the consumer space and you need to do is open up the majority of the apps on our phones or tablets and there is some interaction point to give the user a reward for using the tool. Scott gets into his product Qonqr which is described as the board game Risk and Foursquare together. Scott gets into the different mindsets of gamers (Bartle Index) and how you can use these mindsets to get the most out of your team through gamification techniques.

  • Implementing a wrapping wire (like the Worms Ninja Rope) in a 2D physics engine

    - by Andrew Russell
    I've been trying out some rope-physics recently, and I've found that the "standard" solution - making a rope from a series of objects strung together with springs or joints - is unsatisfying. Especially when rope swinging is relevant to gameplay. I don't really care about a rope's ability to wrap up or sag (this can be faked for visuals anyway). For gameplay, what is important is the ability for the rope to wrap around the environment and then subsequently unwrap. It doesn't even have to behave like rope - a "wire" made up of straight line segments would do. Here's an illustration: This is very similar to the "Ninja Rope" from the game Worms. Because I'm using a 2D physics engine - my environment is made up of 2D convex polygons. (Specifically I am using SAT in Farseer.) So my question is this: How would you implement the "wrapping" effect? It seems pretty obvious that the wire will be made up of a series of line segments that "split" and "join". And the final (active) segment of that line, where the moving object attaches, will be a fixed-length joint. But what is the maths / algorithm involved for determining when and where the active line segment needs to be split? And when it needs to be joined with the previous segment? (Previously this question also asked about doing this for a dynamic environment - I've decided to split that off into other questions.)

  • Continuous Physics Engine's Collision Detection Techniques

    - by Griffin
    I'm working on a purely continuous physics engine, and I need to choose algorithms for broad and narrow phase collision detection. "Purely continuous" means I never do intersection tests, but instead want to find ways to catch every collision before it happens, and put each into "planned collisions" stack that is ordered by TOI. Broad Phase The only continuous broad-phase method I can think of is encasing each body in a circle and testing if each circle will ever overlap another. This seems horribly inefficient however, and lacks any culling. I have no idea what continuous analogs might exist for today's discrete collision culling methods such as quad-trees either. How might I go about preventing inappropriate and pointless broad test's such as a discrete engine does? Narrow Phase I've managed to adapt the narrow SAT to a continuous check rather than discrete, but I'm sure there's other better algorithms out there in papers or sites you guys might have come across. What various fast or accurate algorithm's do you suggest I use and what are the advantages / disatvantages of each? Final Note: I say techniques and not algorithms because I have not yet decided on how I will store different polygons which might be concave, convex, round, or even have holes. I plan to make a decision on this based on what the algorithm requires (for instance if I choose an algorithm that breaks down a polygon into triangles or convex shapes I will simply store the polygon data in this form).

  • /var/run/httpd.pid missing...

    - by user38043
    Recently one of our web servers httpd stopped working and I haven't been able to find the problem. Today I sat down and went through every directory in the httpd.conf and have found an issue. the /var/run/httpd.pid is missing from the folder. All other files are there and seem to be fine. I cannot create a new file with the same name in vi and I have no idea what could have caused this. I imagine it was caused by a cold reboot at some stage as no other extraordinary processes have been run on this server at the time it went down. I am running CentOS 3. How can I reinstate this file?

  • Packet loss with Broadcom wireless and Ubuntu

    - by stevemegson
    I have a machine with Ubuntu 9.04 and a Broadcom BCM4306 wireless card which has been running quite happily for many months with the b43legacy driver that's suggested by Hardware Drivers. Suddenly, I'm now seeing crippling packet loss, varying between 30% and 90% when pinging the router. My WinXP machine is still quite happy even when sat next to the Ubuntu box, so I assume that it's not some new source of interference. What else is likely to have changed? How should I go about diagnosing and fixing this?

  • Beeping Hard Disk - Seagate 250GB Momentus 5400.6

    - by Pez Cuckow
    I have been trying to repair a laptop that simply beeps instead of booting. After taking it apart I have now realised that it is the hard disk beeping. I know that may sound strange but I guarantee that is what it is! (Currently powered on it's own with a Sata Mains lead). The beeping is slightly faster than one per second there is a link to this recording. This recording was made resting the mic on the hard disk while it was sat on a table on it's own, there are no speakers anywhere near, the sound is coming from the hard disk. Does anyone know what this beep means? Is the hard drive just dead, or is it fixable and the data recoverable? Many thanks,

  • How is IntelliJ better than Eclipse?

    - by NickC
    I know there have been questions like What is your favorite editor/IDE?, but none of them have answered this question: Why spend the money on IntelliJ when Eclipse is free? I'm personally a big IntelliJ fan, but I haven't really tried Eclipse. I've used IntelliJ for projects that were Java, JSP, HTML/CSS, Javascript, PHP, and Actionscript, and the latest version, 9, has been excellent for all of them. Many coworkers in the past have told me that they believe Eclipse to be "pretty much the same" as IntelliJ, but, to counter that point, I've occasionally sat behind a developer using Eclipse who's seemed comparably inefficient (to accomplish roughly the same task), and I haven't experienced this with IntelliJ. They may be on par feature-by-feature but features can be ruined by a poor user experience, and I wonder if it's possible that IntelliJ is easier to pick up and discover time-saving features. For users who are already familiar with Eclipse, on top of the real cost of IntelliJ, there is also the cost of time spent learning the new app. Eclipse gets a lot of users who simply don't want to spend $250 on an IDE. If IntelliJ really could help my team be more productive, how could I sell it to them? For those users who've tried both, I'd be very interested in specific pros or cons either way.
