  • General directions on developing a server side control system for JS/Canvas Action RPG

    - by Billy Ninja
    Well, yesterday I asked on anti-cheat JS, and confirmed what I kind of already knew that it's just not possible. Now I wanna measure roughly how hard it is to implement a server side checking that is agnostic to client input, that does not mess with the game experience so much. I don't wanna waste to much resource on this matter, since it's going to be initially a single player game, that I may or would like to introduce some kind of ranking, trading system later on. I'd rather deliver better more cool game features instead. I don't wanna have to guarantee super fast server response to keep the game going lag free. I'd rather go with more loose discrete control of key variables and instances. Like store user's action on a fifo buffer on the client, and push that actions to the server gradually. I'd love to see a elegant, generic solution that I could plug into my client game logic root (not having to scatter treatments everywhere in my client js) - and have few classes on Node.js server that could handle that - without having to mirror/describe all of my game entities a second time on the server.

  • Anti-cheat Javascript for browser/HTML5 game

    - by Billy Ninja
    I'm planning on venturing on making a single player action rpg in js/html5, and I'd like to prevent cheating. I don't need 100% protection, since it's not going to be a multiplayer game, but I want some level of protection. So what strategies you suggest beyond minify and obfuscation? I wouldn't bother to make some server side simple checking, but I don't want to go the Diablo 3 path keeping all my game state changes on the server side. Since it's going to be a rpg of sorts I came up with the idea of making a stats inspector that checks abrupt changes in their values, but I'm not sure how it consistent and trusty it can be. What about variables and functions escopes? Working on smaller escopes whenever possible is safer, but it's worth the effort? Is there anyway for the javascript to self inspect it's text, like in a checksum? There are browser specific solutions? I wouldn't bother to restrain it for Chrome only in the early builds.

  • How to find the static ip address of my router?

    - by OSX NINJA
    I bricked my Linksys WRT54GS router when trying to change the firmware on it from dd-wrt to open-wrt. In order to unbrick it, I need to be able to do an ftp transfer to it. The problem is that it isn't using DHCP addressing and I can't just use the default ip address of 192.168.1.1. I have to use the ip address it was set at before it got bricked. The problem is I forgot what that number was. Is there some program or script that can find it out?

  • Running programs in cache and registers

    - by OSX NINJA
    In my operating systems class we were shown a picture depicting a hierarchy of memory starting from most expensive and fastest at the top and least expensive and slowest at the bottom. At the very top was registers and underneath it was cache. The professor said that the best place to run programs is in cache. I was wondering why programs can't be run in registers? Also, how can a program load itself into cache? Isn't the cache something that's controlled by the CPU and works automatically without software control?

  • How to telnet into facebook chat

    - by OSX Jedi
    I was able to use facebook chat with an external application using the following information: First, find your Facebook username by going to http://www.facebook.com/your_user/. Next, Open iChat, then select iChat » Preferences and click on the Accounts tab. Click on the + (plus) sign to add a new account, with these settings: * Account Type is Jabber Account * Account name is [email protected], and enter your password * Click the drop-down arrow to reveal Server options. Enter chat.facebook.com as the server name. * Enter 5222 as the port and click Done. Click Done again, and you are good to go. From reading this, it seems that it might be possible to telnet into facebook chat. I tried, but wasn't able to. Is it possible? How?

  • How to convert an MKV to AVI with minimal loss

    - by OSX NINJA
    To convert an MKV to AVI, I do two things. The first thing I do is this: ffmpeg -i filename.mkv -vcodec copy -acodec copy output.avi or this: ffmpeg -i filename.mkv -sameq -acodec copy output.avi Either of these will convert the MKV to an AVI, but the problem is that the video does not play smoothly for some reason. That's fine though, because if I do one more thing it gets fixed: ffmpeg -i output.avi -vcodec mpeg4 -b 4000k -acodec mp2 -ab 320k converted.avi After I do this then the file plays without problem. I had success doing it this way for one file, but then I tried it on another file, and there is a slight, but noticeable loss in video quality. This is the output I get when doing the second step: FFmpeg version 0.6.1, Copyright (c) 2000-2010 the FFmpeg developers built on Dec 29 2010 18:02:10 with gcc 4.2.1 (Apple Inc. build 5664) configuration: libavutil 50.15. 1 / 50.15. 1 libavcodec 52.72. 2 / 52.72. 2 libavformat 52.64. 2 / 52.64. 2 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0.11. 0 / 0.11. 0 Seems stream 0 codec frame rate differs from container frame rate: 359.00 (359/1) -> 29.92 (359/12) Input #0, avi, from 'output.avi': Metadata: ISFT : Lavf52.64.2 Duration: 00:04:17.21, start: 0.000000, bitrate: 3074 kb/s Stream #0.0: Video: mpeg4, yuv420p, 704x480 [PAR 229:189 DAR 5038:2835], 29.92 fps, 29.92 tbr, 29.92 tbn, 359 tbc Stream #0.1: Audio: vorbis, 48000 Hz, stereo, s16 Output #0, avi, to 'converted.avi': Metadata: ISFT : Lavf52.64.2 Stream #0.0: Video: mpeg4, yuv420p, 704x480 [PAR 229:189 DAR 5038:2835], q=2-31, 4000 kb/s, 29.92 tbn, 29.92 tbc Stream #0.1: Audio: mp2, 48000 Hz, stereo, s16, 320 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 I just used arbitrarily large settings on the second step and it worked nicely before but not in this case. What settings should I use?

  • What is an application for "web site recognition"?

    - by OSX Jedi
    This explanation isn't clear to me. Let me describe an application for web site recognition. Suppose that we want to know what everyone is doing with the web at starbuck. We can use wireshark or other programs to sniff all the packets. By grouping all the secondary connections with the primary one, then we would be able to get a much easier picture of user's primary activities. Is this talking about being able to recognize which websites each of the laptops are connecting to?

  • Is it possible to impersonate another WAP by intercepting communication with other client?

    - by OSX NINJA
    There is a well known WAP that lots of people use. Someone comes in with a laptop equipped with a sniffer. The laptop sniffs people trying to log on to the WAP. It intercepts the connection, and when people try to log on to the WAP, they unknowingly log on through that person's laptop instead. All communication between the WAP and people's laptops go through that person's laptop. That person's laptop is able to block access to certain websites that the WAP would normally allow.

  • Customizing Rails XML rendering to include extra properties

    - by Isaac Cambron
    Let's say I have a model like this: create_table :ninjas do |t| t.string name end And the Ninja class with an extra property: class Ninja < ActiveRecord::Base def honorific "#{name}san" end end And in my controller I just want to render it to XML: def show render :xml => Ninja.find(params[:id]) end The honorific part isn't rendered. That makes sense, since it's just a method, but is there a way of tricking it? I'm totally up for answers to the effect of, "You're doing this totally wrong." I'll just add that I really do want to calculate the honorific on the fly, and not, like, store it in the database or something.

  • Completing install of ruby 1.9.3 with Ruby for for Mac OS X 10.7.5 Leopard, Xcode 4.5.2 -- problems with rvm pkg install openssl

    - by user1848361
    First, many thanks in advance for any help. I'm a complete novice with programming and I'm trying to get started with this Ruby on Rails tutorial (http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2) I have been trying figure this out for about 7 hours now and since I don't have any hair left to pull out I'm turning to these hallowed pages. I have searched for solutions here again and again. System: Mac OS X 10.7.5 Leopard, Xcode 4.5.2 I installed homebrew and have updated it multiple times I used homebrew to install rvm and have updated it multiple times I installed git The standard ruby on the system (checking with $ ruby -v) is 1.8.7 My problem is that every time I try to use rvm to install a new version of Ruby ($ rvm install 1.9.3) I get the following error: Ruby (and needed base gems) for your selection will be installed shortly. Before it happens, please read and execute the instructions below. Please use a separate terminal to execute any additional commands. Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' For Opal: Install Nodejs with NPM. See http://nodejs.org/download/ To use an RVM installed Ruby as default, instead of the system ruby: rvm install 1.8.7 # installs patch 357: closest supported version rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems rvm alias create default 1.8.7 And reopen your terminal windows. Xcode and gcc: : I have performed $ brew install libksba and when I try to do it again it tells me that libksba is installed already. When I type "$ rvm requirements" I get: Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' For Opal: Install Nodejs with NPM.

Xcode and gcc: Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2. Xcode 4.1 and earlier: - Ruby will build fine. Xcode 4.2 and later (including Command Line Tools for Xcode): - If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine. - If you don't have gcc-4.2, you have two options to get it: * Install apple-gcc42 from Homebrew * Install osx-gcc-installer Homebrew: If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes: brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Xcode 4.2+ install or/and Command Line Tools for Xcode is required to provide make and other tools. osx-gcc-installer: If you don't use Homebrew, you can download and install osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer. Warning: Installing osx-gcc-installer on top of a recent Xcode is known to cause problems, so you must uninstall Xcode before installing osx-gcc-installer. Afterwards you may install Xcode 4.2+ or Command Line Tools for Xcode if you desire. ** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer. So I assume I have to do something with brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Everything seemed to work fine until "$ rvm pkg install openssl", which returns: Fetching openssl-1.0.1c.tar.gz to /Users/thierinvestmentservices/.rvm/archives Extracting openssl to /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c Configuring openssl in /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c.

  • QuickTimeX in Applescript / Scripting Bridge

    I'd like to be able to grab the metadata of the currently playing file in Quicktime X using ScriptingBridge and Ruby, so far I have the following code require 'osx/cocoa' OSX.require_framework 'ScriptingBridge' @app = OSX::SBApplication.applicationWithBundleIdentifier("com.apple.QuickTimePlayerX") @app.documents.each do |movie| # What now?! end But I can't find any functions in QuickTime X's applescript dictionary to get the metadata from a document object (the same data you can see in QT's 'Show Movie Inspector' HUD) — does anyone have any ideas?

  • get_bookmarks() object doesn't return link_category

    - by ninja
    I'm trying to fetch all link-categories from the built in Wordpress linklist (or bookmarks if you will). To do this, I simply stored all links in a variable like this: <?php $lists = get_bookmarks(); foreach($lists as $list) { $cats[] = $list->link_category; } ?> To my surprise even var_dump'ing $cats gave me "String(0)", so I var_dump'ed out $lists instead, and it gave me this: array(8) { [0]=> object(stdClass)#5126 (13) { ["link_id"]=> string(1) "1" ["link_url"]=> string(27) "http://codex.wordpress.org/" ["link_name"]=> string(13) "Documentation" ["link_image"]=> string(0) "" ["link_target"]=> string(0) "" ["link_description"]=> string(0) "" ["link_visible"]=> string(1) "Y" ["link_owner"]=> string(1) "1" ["link_rating"]=> string(1) "0" ["link_updated"]=> string(19) "0000-00-00 00:00:00" ["link_rel"]=> string(0) "" ["link_notes"]=> string(0) "" ["link_rss"]=> string(0) "" } Now, codex.wordpress.org is a default link that comes with wordpress, it's in a category called "Linklist", and as you can see, the object contains everything about that link, EXCEPT the categoryname. According to the codex this object should contain a field named "link_category", so I'm getting confused here. Am I missing something? Is the function broke? Regards NINJA

  • Encoding over SSH Issues

    - by user1104160
    I have a Linux machine and a Windows machine, both using Vim with the Powerline plugin. They both work great with patched fonts. Next, I want to SSH onto an OSX 10.6 machine and also use the Powerline in the terminal with Vim. However, I get weird symbols with normal mode ("^^B" in one area) and fancy mode ("~@" and "~B" spread throughout the bar. I thought this mixup was an encoding issue, but when I look at Putty's encoding it is using UTF-8 and the same with the Ubuntu terminal. Additionally, on the OSX machine, "locale" returns "en_US.UTF-8" for all variables (I set it to do that in order to troubleshoot). However, the symbols are still showing. I am using a patched font (Inconsolata, the same one as the Ubuntu terminal) for the OSX terminal, so I am stumped. Is there a missing component to this equation? Are there additional problems that can arise from SSH encoding? On the OSX end, additionally, these same symbols appear, so it may not even be related to SSH and therefore I'm totally lost.

  • Route specific network traffic through vpn in virtualbox guest

    - by Sander
    I am running OSX with a windows server 2008 guest in Virtualbox. My goal is to route some of the network traffic in the host through the server guest. This is because the win2008 server has a VPN connection to my workplace using a Smartcard solution which can not operate on OSX. My current set-up is like this: OSX (Host): connected to the internet via en01 Win2008 (Guest): connected to the internet using NAT (lan1 in guest) has a SSTP VPN connection to my workplace is connected to the guest using an Host Only Adapter vboxnet0 (LAN2 in guest) The important part is about the host (OSX). Primarily I want all network traffic to just go through en01. However, all traffic which can only be accessed through the VPN must go through the guest and through the VPN. I have one specific FQDN which can only be accessed through the VPN (say corp.mycompany.com). I do not know much about networking. I thought I would be able to get it to work by bridging together LAN2 and LAN1 but this didn't seem to work this: http://archives.aidanfindlater.com/blog/2010/02/03/use-vpn-for-specific-sites-on-mac-os-x/ using a loopback adapter on WinXP (when I did not have win2008 yet, but this doesn't work because I can't create a PPTP connection) And I've also read about Routing and Remote Access but I have no idea on how to use this. Can someone help me in the right direction?

  • Can simple javascript inheritance be simplified even further?

    - by Will
    John Resig (of jQuery fame) provides a concise and elegant way to allow simple JavaScript inheritance. It was so short and sweet, in fact, that it inspired me to try and simplify it even further (see code below). I've modified his original function such that it still passes all his tests and has the potential advantage of: readability (50% less code) simplicity (you don't have to be a ninja to understand it) performance (no extra wrappers around super/base method calls) consistency with C#'s base keyword Because this seems almost too good to be true, I want to make sure my logic doesn't have any fundamental flaws/holes/bugs, or if anyone has additional suggestions to improve or refute the code (perhaps even John Resig could chime in here!). Does anyone see anything wrong with my approach (below) vs. John Resig's original approach? if (!window.Class) { window.Class = function() {}; window.Class.extend = function(members) { var prototype = new this(); for (var i in members) prototype[i] = members[i]; prototype.base = this.prototype; function object() { if (object.caller == null && this.initialize) this.initialize.apply(this, arguments); } object.constructor = object; object.prototype = prototype; object.extend = arguments.callee; return object; }; } And the tests (below) are nearly identical to the original ones except for the syntax around base/super method calls (for the reason enumerated above): var Person = Class.extend( { initialize: function(isDancing) { this.dancing = isDancing; }, dance: function() { return this.dancing; } }); var Ninja = Person.extend( { initialize: function() { this.base.initialize(false); }, dance: function() { return this.base.dance(); }, swingSword: function() { return true; } }); var p = new Person(true); alert("true? " + p.dance()); // => true var n = new Ninja(); alert("false? " + n.dance()); // => false alert("true? " + n.swingSword()); // => true alert("true? " + (p instanceof Person && p instanceof Class && n instanceof Ninja && n instanceof Person && n instanceof Class));

  • Bluetooth mouse Logitech M555b not recognized on a Macbook Pro 8.2

    - by Pierre
    I just bought a Logitech M555b Bluetooth mouse today. My computer (a Macbook Pro 8,2) has a bluetooth connection, and it works perfectly fine on Mac OSX (I set up a new device, click the connect button on the mouse, and voilà, done in 5 seconds). I cannot get it to work on Ubuntu 12.04. When I follow the same steps as on Mac OSX under Ubuntu 12.04, Sometimes I will see the mouse name appearing for 1 second on the screen, and if I'm fast enough to click on "Continue", I will have a message telling me the pairing with my mouse failed. Here are the steps I follow: Turn off Bluetooth on Ubuntu Turn Bluetooth on. Bluetooth icon Set up new device... Turn on the mouse, and press the Connect button. Press "Continue" on the Bluetooth New Device Setup screen I see the mouse name for one second, but then it disappear. Click on PIN options... to select '0000'. ... nothing, Ubuntu won't see anything. In the /var/log/syslog, I have the following information: May 27 23:26:16 Trane bluetoothd[896]: HCI dev 0 down May 27 23:26:16 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been disabled May 27 23:26:58 Trane bluetoothd[896]: HCI dev 0 up May 27 23:26:58 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been enabled May 27 23:26:58 Trane bluetoothd[896]: Inquiry Cancel Failed with status 0x12 May 27 23:28:26 Trane bluetoothd[896]: Refusing input device connect: No such file or directory (2) May 27 23:28:26 Trane bluetoothd[896]: Refusing connection from 00:1F:20:24:15:3D: setup in progress May 27 23:28:26 Trane bluetoothd[896]: Discovery session 0x7f3409ab5b70 with :1.84 activated I tried for an hour, I restarted my computer, re-paired the mouse on Mac OSX, etc. Sometimes when I restart the computer, I have a dialog box showing up saying that the mouse M555b wants to access some resources or something, if I click "Grant", or even if I tick "always grant access", nothing happens... How can I get the Bluetooth to work properly? Help!

  • Personalisation of the Ubuntu interface

    - by Ben
    It's quite hard to phrase this question as the answer is very subjective and I don't know the right terminology to ask for what I want, but I will try my best. I love linux and would love to use it full-time as my main OS but the one think I have a problem with is the look of it. In my opinion it looks like it was designed for a child and I like my computer to look stylish rather than dated (this is opinion obviously). I like the look of OSX but there are certain things that I don't like, so no, I am not asking the age old question of "how do I make ubunutu look like OSX"...most of the attempts I have seen of this have been pretty poor when put up against the real thing so I just want to take certain things from it. Things I'd like to take from OSX: Spotlight (I don't like the Unity dashboard-esque thingy) Expose Spaces Dock (at the bottom) Icons (apart from the apple one) Look of file manager - its more pleasant to navigate around the file system. Closing an application window doesn't actually quit the program, so when you next launch it - it is instantaneous. Global menu (at the top) What are the latest Ubuntu alternatives to these? When it comes to actually changing the look of Ubuntu what should I be looking at? I know the following exists: Shell theme Icons Fonts ...but is there anything else I need to look into to actually change the look? I hear the term "Window Manager" thrown around, but I don't actually know what that is. What are good sources for reviews/links to the latest and greatest customisation techniques? Ubuntu now comes with Unity which I don't like very much. What are my alternatives? Should I look into Gnome3 or switch to classic desktop which is Gnome2 if I recall correctly? I hope I haven't put too much in one question and that it makes sense. Thanks.

  • Install Mac OS Lion on Macbook with existing Ubuntu 12.04 dual boot

    - by kash
    I don't usually create my own questions, because I can find what I need through other people's questions. However, this one doesn't seem to be anywhere, except in one place where someone is talking about not using Apple hardware. So here it goes. I am using Apple hardware. I have a MacBook 1,1 with Intel Core2Duo running Ubuntu Precise Pangolin flawlessly. I never considered starting with Mac OSx and dual-booting because I never liked Mac OS. Now that I'm realizing that the only way I'm going to be able to run my DAW (Reaper) nicely and use a Firewire recording interface is to run Mac OSx, I'm considering it again. I want to go the opposite direction of most people and install Mac OSx next to an existing Ubuntu installation and have a boot menu with refit. I've installed refit in Ubuntu and I've converted the .dmg file for Mac OS Lion to a .iso file. Now, should I mount the .iso in Ubuntu and run it there, or burn a DVD and restart? I'm trying to gauge how to do this without hurting my existing Ubuntu installation. I will of course keep looking for existing answers in the meantime.

  • Cross-platform builds with OGRE3D via CMake. Any tips?

    - by frarees
    I've been trying to compile a simple project for both OSX and Windows platforms, using OGRE3D, but I've got some problems on the way. I'm using CMake to create my platform specific project files (VS solution & Xcode project). Some problems I found are: OGRE3D source is distributed in 2 flavors, Windows sources and UNIX/OSX sources. In OSX, compiling dependencies (freetype, FreeImage and specially OIS) is such a pain. I don't know how to handle precompiled dependencies (they exist for both Win & Mac). May sound like a noob question, but I would appreciate some tips on this. Resources, forum posts, anything. There exists any "cross-platform base project for OGRE3D" on the net? Would be really helpful if someone who already managed to do this can bring some light. Btw, I'm not basing the project on OGRE3D, it's just that is the biggest library I'm probably using, so I depend a lot on it. Thanks in advantage!

  • Ubuntu Raring on iMac 2008; graphics update ATI Radeon HD 2600 Pro broke my Raring this morning!

    Was working on my iMac(2008) 20,5" this morning when again some GLX etc updates appeared! As usual I let the update-installer do it's job; when finished updating, my screen got scrambled; I can not work anymore as the screen shivers, shakes and graphics is one big mess. Ctrl+Alt+F1 does not work either as most of the time my screen is black completely! When booting into OSX 10.8.5 (Raring dual boot with OSX 10.8.5), OSX graphics works flawlessly! Can anybody indicate me which ATI Radeon drivers I can download which repairs the 'malversation' of this mornings updates? I guess I will have to startup with some rescue boot disk (Knoppix?) to do manipulations… As I'm still a noob as well I need clear explanations (please). Raring worked perfectly in dual boot on my iMac until this mornings updates! Needles to say the 'final resort' is restarting (re)installation of Ubuntu Raring, but want to attempt to rescue my present 13.04. Thank you! Kind regards, Gaytan!

  • Squid + Dans Guardian (simple configuration)

    - by The Digital Ninja
    I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

  • Clients didn't switch to secondary DNS server during fail over

    - by The Digital Ninja
    I have two internal dns servers set up and all my servers have both of them in the resolv.conf Our main dns server went down and suddenly no server could see each other. I edited a few of the servers resolv.conf manually and committed out the first (down) dns server and that machine would instantly be able to ping again. What did I do wrong, does it not auto switch to the secondary dns server when it times out? # File managed by puppet nameserver 192.168.146.100 nameserver 192.168.159.101 ;nameserver 72.14.188.5 domain example.com search example.com

  • winbind failing after a semi-random amount of time

    - by The Digital Ninja
    I have winbind set up to authenticate to our AD for samba shares. This is the third such server, and the only one having any issues. It seems after a random amount of time samba shares will just stop working. Winbind processes seem to be running but restarting them seems to fix the issue for a while. Looking at the logs have been kind of hit an miss and I don't know exactly when it fails. One interesting thing is that it seems to be pulling from another domain controller that it shoudlnt. I censored out the domain name in this example. But isnt there some way to block authentication to a domain? I'm not sure if this is a symptom or a cause of the issue.
