  • How to secure an Internet-facing Elastic Search implementation in a shared hosting environment?

    - by casperOne
    (Originally asked on StackOverflow, and recommended that I move it here) I've been going over the documentation for Elastic Search and I'm a big fan and I'd like to use it to handle the search for my ASP.NET MVC app. That introduces a few interesting twists, however. If the ASP.NET MVC application was on a dedicated machine, it would be simple to spool up an instance of Elastic Search and use the TCP Transport to connect locally. However, I'm not on a dedicated machine for the ASP.NET MVC application, nor does it look like I'll move to one anytime soon. That leaves hosting Elastic Search on another machine (in the *NIX world) and I would probably go with shared hosting there. One of the biggest things lacking from Elastic Search, however, is the fact that it doesn't support HTTPS and basic authentication out of the box. If it did, then this question wouldn't exist; I'd simply host it somewhere and make sure to have an incredibly secure password and HTTPS enabled (possibly with a self-signed certificate). But that's not the case. That given, what is a good way to expose Elastic Search over the Internet in a secure way? Note, I'm looking for something that hopefully, will not require writing code to provide shims for the methods that I want (in other words, writing forwarders).

  • Deep recursion in WHM EasyApache software update causes out of memory

    - by Ernest
    I was trying to load some modules with EasyApache in a software update (WHM) cause I need to install Magento ecommerce. I did the first EasyApache update. However, one module I needed was not loaded. I loaded later but whenever I check Tomcat 5.5 in the profile builder I get: -- Begin opt 'Tomcat' -- -- Begin dryrun test 'Checking for v5' -- -- End dryrun test 'Checking for v5' -- -- Begin step 'Checking jdk' -- Deep recursion on subroutine "Cpanel::CPAN::Digest::MD5::File::_dir" at /usr/local/cpanel/Cpanel/CPAN/Digest/MD5/File.pm line 107.

  • Trust my work domain on a Dev Domain without a domain level password

    - by Vaccano
    I setup a virtual machine to host a dev version of TFS (to test plugins on). Getting a computer on my work domain requires large amounts of red tape and paperwork that I would rather not do. I created my own domain the the VM and I would like to trust all users from my work domain on that VM Domain. But when I tried to setup the trust I needed a password from my work domain (which I don't have). Am I trying to do something nefarious? I just want to be able to authenticate to my Test TFS (VM) Server as me (my login on my work domain). Is there a way to do that with out having to have a domain level password for my work domain? (My VM is a Windows Server 2008 R2 server)

  • nginx can't load images,css,js

    - by EquinoX
    When I point to a URL in nginx where it has images extension such as: http://50.56.81.42/phpMyAdmin/themes/original/img/logo_right.png (as example) it gives me the 404 error as it can't find the file, but the file is actually there. What is potentially wrong?

  • Replace text with spaces in MySQL

    - by javipas
    I'm trying to do a global replace of search in my database, which has a lot of articles with a double carriage return because of this code: <p> </p> I'd like to replace this in my WordPress blog so instead of that appears... nothing, and so I can delete the CR. I've tried this on my database UPDATE wp_posts set post_content = replace (post_content,'<p> </p>',''); but didn't work. Why? Do I have to add special thinks to consider the space between the <p>and the</p>? Mmm. Good points, both Jon Angliss and Wim. Jon, as you could have guessed, the database shows no entries with that text string. So there's something going on inside the post_content field. Wim, the famous   was replaced previously, but there are still hundreds of posts that for some reason have something different between the p and the /p tags. I've done a search of one of the posts with this error: mysql> select * from wp_posts where post_title like '%3DVisionLive%'; And looking in the wp_content field, this is a little piece of the post: Phil Eisler, responsable de la divisi?n 3D Vision.?</p> <p>?</p> <p>Este portal ser? por tanto No spanish tilde (accent) shown on the terminal, and instead of an space there's a quotation mark between the p and the /p tags. I've tried to replace <p>?</p>, but again, no results. There's some character (or several) there, but I don't know how to discover that. Maybe it's the character set of my terminal, but I've accessed the database from phpmyadmin and in that case there's a space character between the p and the /p. Weird.

  • Configure ASP.NET Application to Read Mapped Network Drive

    - by Bob
    Is it possible to configure an ASP.NET application under IIS 7 so it can read files stored in a mapped network drive? I'm not trying to serve up the contents of the drive. I simply need to read the contents within the ASP.NET application. I've searched the Web and haven't really found a solid answer. The questions in my mind are: Is this possible via configuration (i.e. I cannot modify the client code)? If so, what are the step by step instructions. If it is not possible, I'm fine with that. I already know UNC paths work but using them drastically changes the work flow. Thanks! Bobby

  • Parse HTTP requests through Wireshark?

    - by diogobaeder
    Hi, guys, Is there any way to parse HTTP request data in wireshark? For example, can I expose the request parameters upon an HTTP GET request (being sent by my machine), so that I don't need to read the (sometimes) truncated URL and find them by myself? I was using Tamper Data and Firebug, on my Firefox, to analyse these requests, but they're not as reliable as a stand-alone tool for monitoring my network interface, but wireshark keeps data too raw concerning HTTP flow. If you guys know any other stand-alone tool that does this (must be Linux-compatible), please tell me. Thanks!

  • Need to link WP Blog with Rails App on Heroku

    - by John Glass
    I have a client who wants to migrate his Rails app to Heroku. However the client also has a blog associated with his domain that runs on WordPress. Currently, the WordPress blog is running happily alongside the Rails app, but once we migrate to Heroku, that clearly won't be possible. The url for the app is like http://mydomain.com, and the url for the blog is like http://mydomain/blog. I realize that the best long-term solution is to redo the blog in a Rails format like Toto or Jekyll. But in the short term, what is the best way to continue hosting the WP blog where it is (or somewhere) but use Heroku to run the app? The client doesn't want the blog to be on a subdomain, but to remain at mydomain/blog for SEO reasons and also since there is traffic to the blog. I have two ideas: Use rack_rewrite or refraction (or just a regular old 301 and Apache mod_rewrite) on the old (non-Heroku) server to redirect the main url from the old site to Heroku. In this case, I can just leave the Wordpress blog running happily where it is. I think?? Is there a reason to choose one of those options (rack_rewrite, refraction, or mod_rewrite) over the others if I do it this way? Switch the DNS info to point to the Heroku site, and then use a 301 redirect from the blog to the old site. But then I'll have to get the old (non-Heroku) site on a subdomain and use some kind of rewrite rules anyway so it looks like it isn't a subdomain. Are either of these approaches preferable, or is there another way to do it that's easier that I'm missing?

  • How can I tell if ZFS (zfs-fuse) dedup/compression is applied to a particular file?

    - by asari
    I have a zfs formatted partition using zfs-fuse for linux (Ubuntu). I had used it for a while, and then enabled dedup and compression on it (zfs set compression=on/dedup=on). Now I think I have some files that are dedup'ed and compressed, and file that are not yet. It was OK, but sometimes I was confused. Let's see, following command would consume almost 4GB of my zfs storage: cp oldfile.4GB newfile.4GB .. and this would consume almost zero: cp newfile.4GB newfile.4GB.2 This is because the old file is not yet compressed, so dedup not happened, I think. My idea is -- if I can find old files that are not yet dedup/compressed, I can perform batch copy/rename/remove them to eliminate duplicity and redundancy. But how I can check that? I know I can re-copy whole contents of my storage should work (even better with checking the time stamp of each file), but I'd be happier if I have zfsstat-like tool that shows some file properties.

  • Emulate "Go to Dekstop/Home/etc." behavior in OS X via AppleScript

    - by pattulus
    OS X has build in support for going to certain Folders (Home, Utilities, Desktop, etc.) via a Shortcut. I wanted to emulate this behavior for the the Downloads Folder. The only thing that is missing the script below is that it won’t succeed when no window is opened in the Finder (see Error message). tell application "Finder" activate set target of Finder window 1 to folder "Downloads" of folder "username" of disk "Macintosh HD" end tell Error message: error "Finder got an error: Can’t set Finder window 1 to folder \"Downloads\" of folder \"username\" of disk \"Macintosh HD\"." number -10006 from Finder window 1 It great if you know about some kind of 'if-compliement' that triggers opening the Downloads Folder in case there is no window 1 open in the Finder. Thanks in advance.

  • Why does Ubuntu's Nautilus display a folder called "Examples" while the console displays "examples.desktop"

    - by broiyan
    These folders occur at /home/username. How does this name discrepancy arise? (Uppercase E versus lowercase e.) It seems to be a shortcut to /usr/share/example-content. How can I delete /usr/share/example-content/Ubuntu_Free_Culture_Showcase without using the command line? One possible answer is to make a privileged Nautilus using something like these SUSE instructions (link below). Unfortunately "gnomesu nautilus" gives me a "gnomesu: no such file" message and "sudo nautilus" does not do anything when added to the properties of the Launcher. Update: "sudo nautilus" from the console let's me delete but there is a mess of error messages. http://forums.opensuse.org/english/get-technical-help-here/how-faq-forums/unreviewed-how-faq/426153-how-nautilus-super-user-mode-gnome.html

  • Won`'t read Unicode characters over NFS mount ?

    - by Julz
    Hello, I'm getting this strange issue when trying to play mp3's containing unicode characters ( accents ) over an NFS on OSX, it's all good over AFP, but I'm setup with NFS because it's a linux server on the other end . This is my disk utility setup : nfs://192.168.1.112/Music advanced mount parameters : -P , nolocks nosuid The strange thing is that I can see those files in the finder ( with the accents .. ) but I cant play them !! So Im wondering if it's an unicode issue, since I can see the files properly or a permission issue since I can't play them, but them it wouldn`t make sense that I can't play ONLY the files containing accents .. help ?? Thanks

  • eMachine W5243 won't POST; fans run but optical drive will not open.

    - by NicciAdonai
    Symptoms are what is described in the title. The machine reacts to the power button being hit by spinning up the two fans: CPU and PSU. The hard drive (SATA) spins up as well. No other reaction. This one symptom is particularly weird, though: the optical drive will not open with the IDE cable attached, but if I unplug it from the mobo it will. I can turn the PC on with it attached, won't open; then unplug IDE while it is still on, WILL open; then plug IDE back in with the PC STILL ON, WON'T open. I have disconnected every peripheral unnecessary to POST. These include: mouse/keyboard, PCI modem, the IDE optical drive (power and data), and the SATA HDD (power and data). Video is onboard. The only two things connected are DB15 video and power cable. There were 2 512 MB DDR2 sticks of RAM in it. I have tried running it with just one of them, then switched the other in. Currently seated is a completely different 1 GB stick that I keep around for troubleshooting purposes, and I have tried it in both slots. I have replaced the CMOS battery with a used one I had lying around, and which worked in the computer it came out of. I have tested the PSU with a tester to confirm it was good, then tried connecting another PSU just in case--same symptoms. I have even tried a suggestion I found elsewhere on this site wherein one disconnects power from the PSU and then presses the PC's power button twice, thereby "resetting" the PSU. Currently I am trying yet another suggestion: turn it on and wait an inordinate amount of time for POST. Any help would be appreciated.

  • How to make Windows 7 machine allocate a lot of hard disk cache?

    - by Jian Lin
    I am recording some game play capture (recording playing of PS3 or Wii) using a PC with Windows 7 and Hauppauge 1212 HD Recorder, and I have 4GB of RAM... is there a way to increase the size of Windows 7's hard disk cache size so that writing to the hard drive can be super fast? Since there is at least 1.5GB of RAM not being used, something like allocating 1GB just as hard disk cache, is it possible?

    Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

  • virtualbox snapshot size

    - by intuited
    I've started using Windows 7 under VirtualBox on an Ubuntu 10.10 host. I took about 6 snapshots over the course of setting up the VM from the Windows restore image that came with the computer. My installations were more or less limited to windows updates, antivirus, and the VB Guest Additions. I uninstalled much more than I installed. The VM was running for about 24 hours total. The snapshots increased in size at a worrisome rate, even when the machine was idle: the snapshot .vdi file for the period between 11:22 PM and 9:02 AM is 6 gigs in size; during that time very little happened. The other .vdi files are between 0.5 and 3 GB, most between 1 and 2 GB. The corresponding .sav files are between 0.5 and 1 GB. The Internet connection where I was doing this is limited to 30KB/s download, which, constantly saturated, works out to less than 3 GB per 24 hour period. Is this normal? Is there something that can be done to make snapshots more practical? update On starting up the VM again, I've noticed that mscorsvw is using significant processing time. Apparently this process [precompiles .NET assemblies]. This may have been going on during the period when I was taking snapshots, which might explain some of the snapshot size increase. I would be somewhat surprised to learn that this could be responsible for over 10 GB of additional disk usage, or that it would run for roughly 24 hours. Is this possible?

  • Convert raw IMAP server data into local folders, then upload partial dataset to new IMAP server?

    - by Manca Weeks
    I am transitioning a company with about 30 IMAP accounts, loaded with data (about 77GB total), to a new email host. The majority of the data will be converted into a local archive and distributed to the company computers as a static reference data set. The server side folders the users absolutely cannot do without being on the server will be uploaded back to the new server. I used Mac OS X Mail (Snow Leopard 10.6.6) to download the content. I notice some messages have the name [xxx].partial.emlx, which leads me to believe they have not been downloaded all the way. I have root access to the mail server data and could download the IMAP server data via FTP. I am not sure what utility to use to convert that data to local Mail.app mailboxes. Furthermore, I would appreciate any input on the best way to upload a portion of the data to the new server (GoDaddy), preserving the original dates of the messages. edit OK - forget the raw server data. I found a script that apparently does pretty good archiving IMAP folders to local mbx files. My main quest now is to batch upload a mailbox hierarchy to the new IMAP server without having to start-stop and deal with similar issues. Anyone know of a utility (hopefully for OS X, but if not, I'll fire up my XP virtual system...) that would be capable of this? Thanks, M

  • Time for the yearly Microsoft Pilgrimage known as the MVP Summit

    - by drsql
    One of the most fun events of the year is the MVP Summit if perhaps for no other reason than my preparation for it is packing a suitcase. No presentations to write, prepare for, nothing. No activities that I have to do anything more than show up with my 2 shovels. One for the amazing amounts of knowledge that will be flowing from the Microsoft folks to us, and the other is actually more of a fork, to get all of the great food they serve us in with.  The whole event is a lot like any other conference,...(read more)

  • Bug! Slow Sums and Averages

    - by Paul White
    It’s a curious thing about SQL that the SUM or AVG of no items is not zero, it’s NULL. In this post, you’ll see how this means your SUM and AVG calculations might run at half speed, or worse. As with most of my blog entries though, today’s instalment is not so much about the result, but the journey we take to get there. Before we get started on that, I just want to mention that there’s a problem with the Google Reader feed for this blog, so those of you that use that will have missed two recent entries: Seeking Without Indexes and Advanced TSQL Tuning: Why Internals Knowledge Matters. Accessing the site directly always works of course :) Ok, on to today’s story. Take a look at this query:...(read more)
