• Trying to figure Windows 2008 Server and Active Directory - complete novice!

  - by Simon E

  I am a novice in networking and I want to learn more about Windows Server 2008 and Active Directory. Basically I have serveral Windows 7 PC's in my home and an IBM server with Win Server 2008 installed. I have enabled Active Directory and set the server to have a static IP. Thats as far as I have got and I feel a little overwhelmed at the moment as I am not sure what to do next. What I eventually want to do is have the Windows 7 PC's to be able to be authenticated by the server - basically a mock up of what most large or medium sized businesses/organisations run. Sorry if I sound a bit sketchy, but I understand some things but not the whole picture, I guess I just need confirmation that I am sort of on the right track :) Also what are some good resources out there you can point me to, what are the absolute basics I need to to get started so I can further my learning?

• How do I set up a proxy server for home with bandwidth control, download limit options?

  - by Quakeboy

  3 room mates share a single 2 Mbps connection. Have a 40GB per month download limit beyond which speed drops to 256Kbps which is annoying. One of the roommates abuses the connection by downloading beyond his quota limit. I have a Netgear WNR1000v2 Wireless router + ADSL Modem to connect to the internet. We all access internet via Wireless router which connects to ADSL Modem. I need a free proxy solution which can help me set 40GB / 3 (13 GB) limit for each person (every person has 2 devices - a PC and a phone with Wifi) Uniform Bandwidth control - when 2 people browse the internet they should get 1 Mbps each, and when 3 people access, they should get 2Mbps divided by 3. After each person crosses their monthly download limit, they should be able to access the internet with 256Kbps speed only or lesser. Can I have a custom firmware on my wireless router do this (or) Do I need a proxy server ? Please point me to any relevant tutorials (for example with Squid).

• Performance Drop Lingers after Load [closed]

  - by Charles

  Possible Duplicate: How do you do Load Testing and Capacity Planning for Databases I'm noticing a drop in performance after subsequent load tests. Although our cpu and ram numbers look fine, performance seems to degrade over time as sustained load is applied to the system. If we allow more time between the load tests, the performance gets back to about 1,000 ms, but if you apply load every 3 minutes or so, it starts to degrade to a point where it takes 12,000 ms. None of the application servers are showing lingering apache processes and the number of database connections cools down to about 3 (from a sustained 20). Is there anything else I should be looking out for here?

• Uptime concerns in case of AWS outage

  - by Aditya Patawari

  I am running an Elastic Load Balancer backup by 2 instances in different Availability Zones in US East. I am using Multi-AZ RDS as well. Ideally this should ensure that if one AZ goes down, it should not effect the app because everything is spread across multiple AZs. But the recent AWS outage took the app down for a long time. I am not sure how this can happen. It would be great if someone can point out what went wrong. Major question here I have is how can I avoid this in future? I can setup app servers across different regions or even providers and use DNS for load balancing but what do I do with MySQL? Read Replicas will introduce some lag which I would want to avoid.

• Started an application through SSH, command line now gone, what happens next?

  - by Chris Dutrow

  Context: This is a very basic question Using Putty and SSH for the first time to do some serious server setup and run into the situation where I have started a process that I do not want to stop. The process is the gunicorn WSGI HTTP Server (running on Centos 6.3). The command I used to start the process is (as per their Quick Start): gunicorn -w 4 myapp:app At this point in the work session, I have lost the command prompt. This must be such a non-issue that it doesn't even enter into an experienced user's consciousness. But unfortunately at my level of experience, I am left with several fundamental questions: Does the fact that I have lost the command prompt mean that the process is still running? How do I get back to the command prompt without killing the process? How do I come back and monitor the process later? How do I eventually kill the process? Any help is appreciated, thanks so much!

• More Win 8 Education is Needed

  - by D'Arcy Lussier

  “My mail doesn’t work”. That’s what a colleague running Windows 8 said to me the day after he installed Windows 8 on his work laptop. “When I click my email, nothing comes up.” I took a look and realized what was going on – he was clicking the Windows 8 UI Mail app and assumed that this was somehow connected to his Outlook which was installed as a desktop app. And so highlights a major educational challenge that Windows 8 will encounter – millions of users used to one style of interface now being introduced to a new one that runs side-by-side with their desktop. At work we had an internal tech user group meeting, and we were showing new features of VS.NET 2012 and Windows 8. When we started talking about the difference between Windows 8 UI Apps (AKA Windows Store Apps), people started asking some good questions: - Can we share a codebase between desktop and Windows Store Apps? - What’s the difference between WinRT and .NET? - Why would we create a Windows Store App and not just a Desktop app? Of course, people are looking at this from a traditional desktop point of view and not a tablet platform, which is really the market that Windows Store Apps will shine on. Still, for developers who not only need to educate themselves but also educate their clients, we’re going to need a better understanding of Windows 8 to see it get real traction within the business/enterprise market.

• Help: My SSL Certificate expired but I can't renew this weekend, is there a way I can disable SSL through IIS?

  - by shogun

  Or perhaps force redirect to HTTP when they request HTTPS? I tried removing the SSL port settings under 'Advanced' but it broke the login page. I don't want to do a deploy/recompile right now but I am able to edit the VIEWS. However I am thinking there may be a way for IIS to do this, but then again I think the .NET code tries to force SSL. Crap. This is bull crap because I was bugging people about getting the new certificate since December and they were like oh we will take care of it... I think it may have even gotten to the point where they were getting annoyed with me hassling them about it! (rant over.) And yes, the key is that more support tickets will be caused by the browser giving a security error than if SSL was removed entirely for one day. Becaues they wouldn't very very likely not notice it being gone.

• Am I supposed to assign the broadcast IP somewhere?

  - by pvieira

  This is a very basic question from a newbie point of view. I have a dedicated server at Hetzner running Windows 2008 R2. I bought a subnet of IP addresses to use in this server. They provided me a given range of IPs, incluind one Ip labeled as "Broadcast". I know how to assign those IPs to the NIC, but should I do something with the Broacast IP, like configure it somewhere on Windows? Or can I just ignore it and I'll be fine? This IP range will be used to host SSL sites.

• decouple software components via nameconvention

  - by csteinmueller

  I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

• Why does my flash video get stuck? (not lag?)

  - by Sk606

  After moving to Ubuntu 10.10 Netbook Edition, I've noticed a strange problem that manifests itself most obviously with streaming videos like youtube and hulu. The video will load and begin playing fine and eventually stop, as though it is buffering. However, it usually happens between 40 and 60 seconds into the clip. The loading indication however shows that it actually isn't buffering anymore of the data, and will just sit there. If I force the clip forward (e.g. click to start the movie somewhere ahead of the stall point) the clip will usually reload quickly and begin playing as expected. Because of the quick load times, and the consistent stop of video, I don't think the problem is related to hardware performance or network throughput. Also, I have none of these problems in 10.04. Rebooting into 10.04 makes the problem disappear. However, one more clue, I also have noticed a higher occurrence of web pages that simply "stop loading" - say, 1/10 clicks while browsing I have to hit "reload" to get the page to load because the page timed out part of the way through. This seems strangely related to the video problem, though is a lot less infuriating. Help! Where do I begin to look with a problem like this?

• How come there is still so much programming work?

  - by jd_505

  First I'd like to say that I am not pretty sure that this question will meet the guidelines. I think it can goes under the "Freelancing and business concerns" bullet, but I am not sure. Anyway, I will give it a shot. I wonder how the programming jobs hasn't yet "dried" because of the software evolution, for example, I am a developer myself, which means that I do care about software (I mean I am not of the type of guys that needs a computer mainly to just browse the Internet), and still I wouldn't mind if I never receive any more updates on my Ubuntu machine. I find that it provides everything I need, and while the updates provide various bug fixes/improvements, I wouldn't mind using it with it's current state for the rest of my life, for 2 years of Ubuntu usage I have never bumped at a serious bug/problem. Another example is Windows, almost half of it's users still use XP, which is practically ancient, yet they find it satisfying all their needs (and I agreee with them). I could go with many more examples, but by now you are understanding my point and my question. While new "trends" appears all of the time (like a new mobile OS) which runs on new platforms and requires some fresh development work, still the majority of the software effort goes in to what I consider as "completed projects", or at least a state of a project which is enough to be considered as completed. Do you have an explanation ? I can't think of the right tags for this question, please edit it the way you find it to be most appropriate. Thanks.

• Proxy between data centers [closed]

  - by dstarh

  Possible Duplicate: Can IIS be configure to forward request to another web server? We are switching data centers (actually datac-center to EC2 to be specific) and some customers have not yet made DNS changes to point the domains to the new load balancers. We are thinking of leaving the existing servers up and just using a proxy server to forward the request to the new load balancer. Can anyone recommend a good proxy server for doing this I've got squid installed but it seems it's fairly easy to just have a fairly wide open proxy server and we don't want this. I want all requests coming in on port 80 to be sent to port 80 at a specific domain (elastic load balancer) the data center env is windows 2k3 and the EC2 env will all be linux but the ec2 env should be irrelevant

• need a different backup solution

  - by DigitalJedi

  I just built a new media/backup server using Ubuntu 12.04 64bit. I installed a hard drive to be used only for music, pictures, and videos and formatted it fat32 so my 1 and only Windows PC could map those folders as netshares. My laptop, also running Ubuntu 12.04, is what I am using the most so new media is first downloaded on my laptop. I've already got the music, videos, and pictures folders from my server mounting as shares on my laptop on boot thanks to some fstab edits and sshfs. Now I'm wanting either an app or script that could backup any new files I add to my local media folders to the mounted folders on my server. I've been Googling all day and found a few apps like rsync but they seem to have issues with ext4 to vfat backups. I thought maybe a script would be best but I'm new to scripting in Linux and don't want to mess anything up. Basically I am looking for something that will backup only newly added files to the server. I figure I could schedule it once a week. There are some stipulations. For example, my local music folder has over 700 folders for each artist/band then sub folders inside those for albums. I want something smart enough to only copy newly added content so I'm guessing the modified date would probably be a good condition if I were scripting. I'm rambling. Any suggestions would be GREATLY appreciated. I'm not finding anything to suit my needs. I'm almost to the point of just learning bas scripting so I can write something but then it will be a couple weeks or so before I have a possible solution and I'd like something in place sooner.

• Subdomain returns error when restarting Apache

• Router for Infrastructure Network

  - by amfortas

  We have an HPC operation that down the years has grown to several racks of gear at three sites, hooked up via Gigabit fiber and Catalyst 2960s (we control the links and switches). Thus far all machines have been on a flat RCF1918 10/8 but we are looking to segment the network in order to streamline matters for iSCSI and generally keep infrastructure equipment away from our end-users. We have now reached a point where we need to consider introducing VLANs for specific subnets and are wondering if it would be worthwhile in the longer run to acquire a small router to keep to keep track of all this stuff and cut down on the complexity of netmasks and routes on host machines, etc. Has anyone here had a similar experience? Suggestions as to suitable equipment would be welcome.

• Why does my system slow down or freeze when there is heavy disk activity?

  - by user72270

  Im a first-time user to Ubuntu-12.04 with WUBI installation. My NoteBook Information : Dell vostro 3450 : i5 2410m, 3 gb ram, intel hd3000, amd 6630m hybrid. Surfing and playing games works flawlessly, however, I'm having huge problems when installing applications and generally copying and moving files. When doing so, system is significantly slower and freezes quite often (Firefox gets bluish, sometimes even black n white). I would say that Ubuntu allocates too much resources on file transfers and installing, but even these tasks are very slow. Here is very specific example : today, i tried to move 6 GB file from win 7 installation. It was good at first, i jumped to firefox but after a while firefox started to randomly turn bluish and mouse was randomly stopping working. It was gradually worse and worse and it got to a point when firefox black n whited and mouse wasn't working at all. I raged and went for some meal, when i got back screen was black. It probably unlogged me due to inactivity, when i pushed random button to bring screen to life i had to wait few minutes to let it show me only my screen background. No log in screen, just background and working mouse. NoteBook fan was working at 100 % so I assumed that file transfer was going on and I left it to work. Nothing then changed for a full hour so I hard rebooted it. File transfer unsuccessful, It transfered hardly 2 gigs. Is this normal ? What to do in these situations ? It didn't let me load system manager and not even terminal. Thanks.

• How do I reduce RAM usage on my server?

  - by Abs

  I have recently launched a site that is very popular but I am having trouble with scalability. My site makes heavy use of FFmpeg and at peak times RAM usage hits the 2 GB point quickly and the swap file starts getting used. CPU usage starts rising too. Users complain that the site is slow. They say this because all FFmpeg instances run very slow because of the number running at the same time. Users make use of FFmpeg on my server in real time. Is there anything I can consider or do to ease down the usage of the server and RAM just shooting up? Maybe there is something better than FFmpeg (!). Is the only solution "throwing some cash" at a more powerful server? I have given little information, please ask for more, so this problem can be solved.

• Finding documentation for /etc/**/*.dpkg-*

  - by intuited

  During upgrades, files with these extensions appear in /etc and its subdirectories. I gather that *.dpkg-dist contains the file that was distributed with the currently-installed version of a package, and *.dpkg-new contains the version from the version being installed, however I'd like to see the docs to be sure that I'm getting it right. Also there are occasionally other similarly named files, eg *.dpkg-original, and I'd like to be able to read up on these. I've checked /usr/share/doc/dpkg for documentation on this, and come up empty; there's no dpkg-doc package; Google doesn't have anything except unanswered questions. Can someone point me to the documentation for this aspect of debian package management?

• Lock manager stops responding (lockd/nfslock), but shows as running

  - by dwaynehoov

  Essentially, lock manager stops responding (lockd/nfslock), but shows as running as a kernel process. If I bounce portmap and nfslock, it has no effect. Doesn't show up in the portmapper registered services rpcinfo -p .. doesn't show nlockmgr. it just shows portmapper and status If I manually remount the drives, it fixes the issue. I'm assuming that the service (lockd) goes stale or hangs when there is no NFS activity? It seems like issuing a mount for NFS volumes "awakens" it and things work once that happens. Please help me nail this down for point me to somewhere to get more information on what might be happening. System info: Linux xxx.yyy.com 2.6.32-300.38.1.el5uek #1 SMP Thu Oct 18 11:51:13 PDT 2012 x86_64 x86_64 x86_64 GNU/Linux cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.8 (Tikanga) cat /etc/oracle-release Oracle Linux Server release 5.8 Thanks

• Split up a screen into regions

  - by nexen

  My task: I want to split up a screen into 3 regions for buffs-bar (with picked items), score-info and a game-map. It doesn't matter are regions intersect with each other or not. For example: I have a screen with width=1; height=1 and the origin of coordinates (0;0) is the left bottom point. I have 3 functions: draw items, draw info, draw map. If I use it without any matrix transformations, it draws fullscreen, because it's vertex coordinates are from 0;0 to 1;1. (pseudo-code) drawItems(); drawInfo(); drawMap(); And after that I see only map onto info onto items. My goal: I have some matrixes for transformation vertexes with 0;0-1;1 coordinates to strict regions. There is only one thing, what I need to do - set matrix before drawing. So my call of drawItems-function is like: (pseudo-code) adjustViewMatrixes_andSomethingElse(items.position_of_the_region_there_it_should_be_drawn, items.sizes_of_region_to_draw); setItemsMatrix(); drawItems(); //the same function with vertex coordinates 0;0->1;1, //but it draws in other coordinates, //because I have just set the matrix for region I know only some people will understand me, so there is a picture with regions which I need to make. Every region has 0;0 - 1;1 inner coordinates.

• Certain websites do not open. Instead a 1*1 image gets displayed

  - by Ranjith - SR2GF

  When I try to visit certain websites like www.bidvertiser.com, www.buysellads.com, a white page shows up, the title bar displays the site name followed by (1x1) in brackets. When I right click, 'View Source' option appears disabled. The Save As.. option shows the file type to be gif. However, when I preview the site in Google search results ( by moving the mouse over ) the screenshot of the site displays well. This happens on all the three browsers on my computer: Chrome, Firefox and IE. What is the problem and how can it be resolved? EDIT: At some point of time, they probably worked on my computer! I think it is a more general problem. The same happens when I click on certain links in Google search results.

• How to Program AWS Spot Instances to Strategically Bid So the Auction is Never Lost Until a Competitor Beats the Maximum I'm Willing to Pay?

  - by Taal

  I believe I'm in the right section of stack exchange to ask this. If not, let me know. I only use Amazon Web Services for temporary type hosting services, so the spot instances are quite valuable to me. I would also just make an instance and start and stop it - but - that doesn't necessarily fit my bootstrapped budget sadly. Anyways, it really kills me when someone outbids me on a spot instance I have (I tend to go for the larger ones which there are fewer of available) and I get randomly kicked off. I know or at least I believe there is a way to program in something somehow to dynamically change your bidding price to beat a potential competitor's if their's is higher than yours. Now, I previously believed Amazon would just charge me for the highest price right above the next lowest competitor automatically (eliminating the need for this) - so if I bid too high, then I only pay what I would of needed to in order to win and keep the auction. Essentially, I thought my bid price was my max bid price. Apparently, according to my bills and several experiments I've done - this is not the case. They charge me for whatever I bid even when I know there is no one else around to counter bid me. I needed to clarify that, but let me get back to the main point: Let's say I'm bidding $0.50, competitor comes in and bids 0.55 cents. I get kicked off. I want to have it to where I'd set a maximum I'm willing to pay (let's say $1.00 here), and then when competitor comes in and tries to bid $.55, my bid is dynamically adjusted to beat his at $0.56 up until he breaks my $1.00 threshold. I've been reading the guides and although they are more or less straightforward, I feel like they leave a few holes in them that end up confusing me. Like, for instance, where do I input said command or when do I do it? Maybe I'm just tech illiterate and need help deciphering these guides. A good start for someone willing to answer/help me decipher this problem would be here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-as-update-bid.html

• SEO Blog Indexing : Dot Wordpress Versus a Registered Domain?

  - by rumspringa00

  I've used Wordpress for a few of my client's sites, mostly small businesses and ecommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using Wordpress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot Wordpress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domian would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong? Thanks in advance!

• Can I share data between two users in an ASP.NET Application?

  - by Dave

  I have an issue with Roles.IsUserInRole function. It take hell amount of time to just check if the logged-in user is in particular role(typ 3-9 sec). I searched to find a solution and arrived on this but I am not sure If I have fully grasped it. What I got from the above, A new derived class is created. Inside that class, there is a list which retrieves all user at once. The next time you check IsUserInRole, you do not use the actual IsUserInRole method but rather use the one you overrode in your class. Is this the correct description? Am I on track? My question is, can data be share between two different users in ASP.NET application? If yes, will the shared data exist only if there is at least one user logged in. If all users logs out, that shared data is destroyed? My point is this data will be created only one time whenever a user logs in. For all subsequent users they can use this data and check their roles against the list? I need a detailed answer. My application has users and different roles. We are using ASP.NET roles.
