• Masquerade traffic from certain source IP to VPN connection

  - by Shuo Ran

  Network Setup: 10.0.0.1 Router: to internet 10.0.0.70 Server: Ubuntu based server,default gateway is 10.0.0.1 10.0.0.51 PC I created a PPTP connection(interface: ppp0) on Server to a machine on the internet, what I want to do is route all the traffic from certain IP address(10.0.0.51) through the PPTP connection and then to the internet. What I did are: Set the gateway on PC(10.0.0.51) as 10.0.0.70 Enabled ipv4 forward on 10,0,0,70 Add the masquerade rule to iptable: iptables -t nat -A POSTROUTING -o ppp0 -s 10.0.0.51 -j MASQUERADE After that, it seems none of the traffic from 10.0.0.51 be redirected to ppp0, instead these traffic are still going through 10.0.0.1 directly. Any thoughts on it?

• Redirect URL to a Tomcat webapp

  - by phs

  I have a Tomcat server with two webapps, app1 and app2 (the app part is really the same). Each app has an independent group of users. I would like the groups to be able to access their respective app using group1.domain.com/app and group2.domain.com/app URLs, meaning that the numbers should be hidden from the URL displayed in browser. I suppose there needs to be a mechanism that would return the correct app based on the group# part of the URL. I have a vague understanding of URL rewrites. Is there a way to do this with only Tomcat? Or do I need Apache HTTP server? I would rather not use Apache if possible, but have no problem going that way if necessary.

• Open Source Outlook and Exchange Alternative (for Calendar and Tasks)

  - by Elmar Weber

  We're using an Exchange Server and Outlook in a private context. Since Exchange is getting more and more of a monster to maintain and is basically the only thing running on a Windows VM Server, I'm looking for an alternative with the following properties: Server based back-end that that can be installed / deployed on my machine and is not dependent on any third party services (e.g. Google Calendar). (Easy) import of existing Outlook calendars, either via some feature of Exchange or by ex- and importing from Outlook. Roughly the basic features of the Outlook calendar (categorizations, series, etc) Synchronization with the iPhone over wireless without a hitch (e.g. double or missing entries) Any recommendations?

• Getting much higher than usual brute-force attempts on cPanel

  - by UserZer0

  Although I have many client accounts on my cPanel based server I'm really the only one who has login information to any of the accounts. I have cPhulk setup to alert me and blocking after 4 failed attempts. I usually have only a handful of bots trying to get in each day(2 hosts ago I never had any), but Today the rate has significantly increased, every 10 minutes or so(no not like clockwork, just averaging). Should I be concerned? Is there anything extra I should be doing, is there any automated reporting services I can use? Thanks.

• Control Windows 8 with a tablet

  - by Frantumn

  It seems much of Windows 8 is based on the idea that it will be running on tablets, and touch screen PCs. I like this, but I don't have a W89 tablet, or a touch PC yet. I'm running W8 on a laptop, and am wondering if there's any way of using my iPad2 as a touch interface with metro? Or another options that'd be nice is if there's a input device similar to Apple's "Magic Trackpad" that would allow me to use hand gestures instead of a mouse cursor when in metro apps. I've seen some cool videos of MS Smart Glass and it would seem that the capabilities are there. But it may just be too early on to do this? I'm not sure.

• A new day has dawned in my SharePoint world.

  - by SPTales

  Until I started working with SharePoint, I never thought I would be blogging.  I am usually a pretty private individual, but this thing called the SharePoint community pulls you in and makes you feel like you should be a part of it, contributing to it and giving something back.  So here I am blogging for the first time – and so begins my tale. I started my work life as a Systems admin, but was given a chance to start working with SharePoint 2007 back in - ironically enough - January of 2007.  It has been downhill from there or uphill depending on your perspective!  I jumped in with both feet and haven’t looked back.  Lucky for me Microsoft gave us a new version to work with.  A new job a couple years ago gave me the chance to work with that new version.  Now I spend my days weaving a tale of SharePoint for a Sales based organization. So why this blog?  To give something back. I spend most days toggling between administration, InfoPath, Branding and design, HTML, JQuery, and XSLT depending on the need.  The blog will detail these projects and solutions as best I can.  Hopefully they will be of use to someone who may be trying to accomplish similar things, just as many of the blogs that I have referenced over the last 5 years have been a huge help and resource for me.

• laptop will not boot after attempting upgrade to 13.10

  - by naerwenya

  I wanted to update my OS to the new 14.04 LTS. I was running 12.04 LTS before and followed the advice that upgrades should be done in steps. I first upgraded to 12.10, which seemed to work fine, and later to 13.10. This was all done through the Software Manager. After the last upgrade, I am no longer able to boot up my computer. The GNU GRUB menu opens up, but after selecting Ubuntu, it just stalls with a blank purple screen. If I select one of the other kernels, it also stalls after "Loading initial ramdisk...". I can't get into the Recovery Menu, either. I'm still rather new to Linux and may have possibly made the situation worse. Unfortunately, nothing has worked yet. I tried reinstalling from a flash drive and on my first attempt, the wizard recognised a previous installation. Unfortunately, the wizard also didn't like how my partitions were set up (I didn't change anything) and gave an error before closing. Unfortunately, I didn't write the error down, but it was about the boot partition. On the next attempt and ever since, the installation wizard has stated that "This computer currently has no detected operating systems." This is strange, because I could see the disk and even access my files when booting up from the USB. At this point, I decided to back up my important files using dropbox. Before losing all my files, I wanted to try the Boot-Repair tool, which also produced no results, and the files are no longer visible when booting from USB. The link to the Boot-Repair log is at http://paste.ubuntu.com/7457249/. If I then proceed through to the "Something else" installation option, I can see that the partitions still exist. This is what they look like: /dev/sda free space (size indicated 1MB) /dev/sda1 efi (33MB of 98 MB used) /dev/sda2 efi (352634MB of 746330MB used) /dev/sda3 swap (3725MB, none used) free space (0MB) Is there any way I might be able to get my computer to work and preserve my files as well?

• Should I Open Source? [closed]

  - by Howdy_McGee

  My company recently created a full javascript, html & css Virtual Tour. Since it is html based there is no real way of securing our information/code so selling it could be flimsy. We are an extremely small company, barely on the map so I was thinking that by making this an open source project it could give us a chance to jump start our SEO by page views alone, especially if we provide documentation. Not to mention hopefully bring a community following on our blog. On the other hand though could this possibly hurt our sales as a web development company? If we are handing out this cool "plugin" we made what keeps people from making it commercial somehow? So I'm trying to weigh the options on whether I should make this Open Source or not and the pros / cons of each especially for a small business. What do you guys think about making things Open Source? How do I know if this product is the right thing to make Open Source? What are some pros and cons to going Open Source?

• Sprite batching seems slow

  - by Dekowta

  I have implemented a sprite batching system in OpenGL which will batch sprites based on their texture. How ever when I'm rendering ~5000 sprites all using the same texture i'm getting roughly 30fps. The process is as followed create sprite batch which also create a VBO with a set size and also creates the shaders as well call begin and initialise the render mode (at the moment just setting alpha on) call Draw with a sprite. This checks to see if the texture of the sprite has already been loaded and if so it just creates a pointer to the batch item and adds the new sprite coords. If not then it creates a new batch item and adds the sprite coords to that; it adds the batch item to the main batch. if the max sprite count is reached render will be called call end which calls render to render the left over sprites in the batch. and also resets the buffer offset render loops through each item in the batch and will bind the texture of the batch item, map the data to the buffer and then draw the array. the buffer will then be offset by the amount of sprites drawn. I have a feeling that it could be the method i'm using to store the batched sprites or it could be something else that i'm missing but I still can work it out. the cpp and h files are as followed http://pastebin.com/ZAytErGB http://pastebin.com/iCB608tA On top of this i'm also getting a weird issue where then two sprites are batched on after the other the second sprite will use the same coordinates as the last. And then when one if drawn after it is fine. I can't seem to find what is causing this issue. any help would be appreciated iv been sat trying to work this all out for a while now and cant seems to put my finger on what's causing it all.

• What are the pros & cons of these MySQL engines for OLTP -- XtraDB, PBXT, or TokuDB?

  - by Continuation

  I'm working on a social website with an approximate read/write split of 90/10. Trying to decide on a MySQL engine. The ones I'm interested in are: XtraDB PBXT TokuDB What are the pros and cons of them for my use case? A few specific questions: PBXT uses log-based structure that avoids double-writes. It sounds very elegant, but the benchmark I've seen doesn't show any/much advantages over XtraDB. Do you have any experience with PBXT/XtraDB you can share? TokuDB sounds VERY interesting. But all the benchmarks I've seen are about single-threaded bulk inserts - inserting 100M rows for example. that's not very relevant for OLTP. What about its performance with large number of concurrent threads writing and reading at the same time? Anyone has tried that?

• Upgraded from 11.10 to 12.04 now no network access

  - by MadeTheLeap

  A few weeks ago I decided I should enter the Linux world and read that Ubuntu is the most widely used release. I installed version 11.10 and it worked perfectly. Just this past week I decided I would do the upgrade to 12.04. The upgrade process itself worked fine. However, when I logged in I no longer had a network connection. I am running an AMD-based PC with a D-LINK DFE-530TXS network card and as I said, it worked fine in 11.10. I have scoured the Internet and come across a thousand slightly varying solutions, but they are too convoluted for someone new to Linux. Not because I can't follow the steps, but because most of the tools/utilities that are referenced (e.g. to compile, install, etc.) are not available when I use the stated steps in the solutions. So....should I re-install 11.10 or is there hope in getting this version to use the NIC that I know works. I have the latest driver from d-link for my NIC but I have no idea how to 'install' it for Ubuntu 12.04 to use. I know you will require additional information, but I wasn't sure what you would need. Thanks in advance.

• What is a quick and easy way to make a minimal news blog that pulls rss feeds? I have 2 days [on hold]

  - by user44188

  My boss wants me to make a website that pulls news from various rss feeds from all over the web. I need to pull something together, that looks pro, quick! I started by going to themeforest and looked around forever, but nothing really looked right. I need something mostly built like this already that I can just alter into our site. I can do most cms, photoshop, some code, I used to do it like this freelance years ago, but it's not really my job now. It just sort of came up suddenly, so I wanna pull through. This is a good example of the overall structure I had in mind, but it just isn't clean enough. All of the news feeds will essentially be about the same criteria, but will pertain to different geographic areas. It would be a huge plus if I could segregate the news visually in some clever way based on geography. (Like a map?) I'm definitely open to all suggestions. I have to get this done by friday!

• Is it possible to get the matched regex from within the apache LocationMatch directive?

  - by tftd

  I'm wondering if the following code should be working: <LocationMatch "/(.*)([/])?(.*)"> Order allow,deny Allow from all AuthType Basic AuthName "Git" AuthUserFile /git/.htpasswd AuthGroupFile /git/.htgroup Require group $1 </LocationMatch> What I am trying to achieve with this is to require a group based on the first regex variable. So if the user goes to http://localhost/a-repository-name he has to be in the group a-repository-name to be able to open the url. For some reason I can't get this code working and apache returns: Authorization of user **** to access /a-repository-name failed, reason: user is not part of the 'require'ed group(s). I guess it's not matching against the proper variable at Require group $1. Is this the right way to be done or I'm missing something?

• What's the best way to install software in Ubuntu?

  - by the0ther

  I'm new to Ubuntu and have been away from Linux for a while. I'm used to Windows and find this tedious on Linux but I want to give it a shot. My tendency is to prefer GUI tools over command-line, and Ubuntu is a distro that seems to cater to usability. I note it is based somewhat on apt-get which I've heard good things about. What's the best practise for installing apps on Ubuntu? Should I prefer to try my options in this order? Synaptic Package Manger apt-get on the command line .tar.gz files (old school)

• Can OpenVPN be set up so the server doesn't have interface that is part of the VPN?

  - by BCS

  I'm looking to set up a VPN (OpenVPN is my first choice but I'm not stuck with it) in such a way that the server that hosts the VPN is not visible from within the VPN. That is; any packet that a client sends via the VPN interface will get delivered to another client's VPN interface or get dropped. In the other direction, the server shouldn't have a VPN interface at all and normal network operations shouldn't be able to send packets on the network. Can this be done? All the docs I have found have assumed that clients will connect via DHCP (this requiring that the server connect at least to that extent) but I can't think of any reason that a VPN couldn't use static IP's or that the DHCP server couldn't be implemented inside the VPN (see edit) server without setting up a VPN interface on the server. Edit: Based on the link on bridged mode from Phil Hollenback's answer it seems that OpenVPN does in fact have the "internal DHCP server" that I'm thinking of.

• CentOS drive mapping? [on hold]

  - by DroidOS

  This is the first time I am posting on this particular StackExchange forum and I hope that I am using the right one for the present question. Briefly, this is what I need to do I am running a web service where users can, amongst other things, upload and store files on the server. What I want to do is to hive off user file storage to a different location so my server (CentOS 64 bit) can concentrate on what it does best - server side scripting and database management. As things stand all user files go into subdirectories in a folder called stash that lies above DOC_ROOT. What I would like to do is Transparently detect all attempts to read/write to stash/sub_folder and get/set file data on a remote server - ideally the latter would be one which replicates files like a CDN so they can be delivered from the closest/fastest location based on where the user's location. Even nicer would be if for all read accesses I could provide a URL that allows the user's browser to fetch the relevant file directly without having to funnel them via my server. I am a relative newbie when it comes to this sort of thing so I hope that I have phrased this question adequately well. From the little searching I done I gathered that WebDAV can be used to map drives to a different location on the web so perhaps that is a starting point. But if that will work I need to Establish how to get WebDAV up and running on my CentOS 64 bit server. Ideally, identify a service that allows this kind of file storage and provides an API I can use in my own scripting. I'd much appreciate any help with this.

• Selectively Including files in C#.net web application [migrated]

  - by segnosaur

  I am attempting to modify an application with the following characteristics: Written in C#.net Using Visual Studio 2010 The application uses a Master sheet to maintain commonality The Master sheet has the following: <%@ Master Language="C#" AutoEventWireup="true" CodeFile="mysheet.master.cs" Inherits="master_mysheet" %> Now, currently, the master sheet has an include file that brings in a common footer: #include file="inc/my-footer.inc" Here's what I want to do: I would like to modify the master sheet to be able to read in a footer based on the value contained in a session variable... i.e. (not real code, but just something to give an idea of what I want) if session("x") = "a" then #include file="inc/my-footer1.inc" else #include file="inc/my-footer2.inc" My first instinct was to go with some vbscript: <script type="text/vbscript" language="vbscript"> document.write("vbscript example.") </script> However, it doesn't run the vbscript code automatically on page load. Does anyone know: - The syntax I need to actually get this to work? i.e. to get the vbscript to run automatically on page load, AND to do the page include? - Or, is there a better way to go about this? (perhaps by doing some coding in C#) Note: I am experienced in C#; however, I haven't done any vbscript since the days of ASP classic, so my knowledge there is out of date.

• In-House DropBox

  - by beardedlinuxgeek

  Dropbox is perfect, but as a company, no one can host anything worthwhile on servers that we don't control. So I've been tasked with coming up with a Dropbox alternative, something in house. GlusterFS is nice, but no offline access. SparkleShare uses Git which isn't great for large files. It also doesn't have windows ports. Any other options? If I were to roll out my own from scratch, what do you think the based way to go about doing this would be?

• Is it possible to power off a PCIe video card/slot? (eg. hot-plug)

  - by CR.

  I'm looking at building a system that supports VT-d so I can pass through a high powered loud video card to a Xen/KVM/whatever VM (host will be Linux based). However, when I'm not using the VM I want to turn the video card off so its fan does not run. The card will not be used when the VM isn't running. Anyone know if this is possible? The PCI-Express hot-plug specification allows cutting power to specific slots but I have never heard of anyone doing it with a video card and my searches for information have turned up nothing.

• Does (should?) changing the URI scheme name change the semantics?

  - by Doug

  If we take: http://example.com/foo is it fair to say that: ftp://example.com/foo .. points to the same resource, just using a different mechanism for resolving it (and of course possibly a different representation, but perhaps not)? This came to light in a discussion we were having surrounding some internal tooling with Git. We have to process some Git repositories, and they come to use as "git@{authority}/{path}" , however the library we're using to interface with them doesn't support the git protocol. I suggested that we should make the service robust in of that it tries to use HTTP or SSH, in essence, discovering what protocols/schemes are supported for resolving the repository at {path} under each {authority}. This was met with some criticism: "We don't know if that's the same repository". My response was: "It had better be!" Looking at RFC 3986, I see this excerpt: URI "resolution" is the process of determining an access mechanism and the appropriate parameters necessary to dereference a URI; this resolution may require several iterations. To use that access mechanism to perform an action on the URI's resource is to "dereference" the URI. Which makes me think that the resolution process is permitted to try different protocols, because: Although many URI schemes are named after protocols, this does not imply that use of these URIs will result in access to the resource via the named protocol. The only concern I have, I guess, is that I only see reference to the notion of changing protocols when it comes to traversing relationships: it is possible for a single set of hypertext documents to be simultaneously accessible and traversable via each of the "file", "http", and "ftp" schemes if the documents refer to each other with relative references. I'm inclined to think I'm wrong in my initial beliefs, because the Normalization and Comparison section of said RFC doesn't mention any way of treating two URIs as equivalent if they use different schemes. It seems like schemes named/based on IP protocols ought to have this notion, at least?

• Live HTML Preview

  - by netbeanstips

  When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

• Should I amortize scripting cost via bytecode analysis or multithreading?

  - by user18983

  I'm working on a game sort of thing where users can write arbitrary code for individual agents, and I'm trying to decide the best way to divide up computation time. The simplest option would be to give each agent a set amount of time and skip their turn if it elapses without an action being decided upon, but I would like people to be able to write their agents decision functions without having to think too much about how long its taking unless they really want to. The two approaches I'm considering are giving each agent a set number of bytecode instructions (taking cost into account) each timestep, and making players deal with the consequences of the game state changing between blocks of computation (as with Battlecode) or giving each agent it's own thread and giving each thread equal time on the processor. I'm about equally knowledgeable on both concurrency and bytecode stuff, which is to say not very, so I'm wondering which approach would be best. I have a clearer idea of how I'd structure things if I used bytecode, but less certainty about how to actually implement the analysis. I'm pretty sure I can work up a concurrency based system without much trouble, but I worry it will be messier with more overhead and will add unnecessary complexity to the project.

• Simplest way to respawn configured number of instances of a specific process.

  So we have an app. which we wan to run multiple instance of it in linux. The number should be configurable. We also want that whenever one of the instance disappears, a new one is booted up. I was looking into C based programs, shell script, python script etc. but I was wondering what would be the most simple, easiest way to do it. Are there any tools out there? Can one simply use some linux built-in functionality? Linux distribution is Red Hat.

• Would SSD drives benefit from a non-default allocation unit size?

  - by davebug

  The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of a solid state drive (seek times massively lower than hard disks) may create a situation where a much smaller allocation size is not detrimental. Were this the case it would at least partially help to overcome the disadvantage of SSD (massively higher prices per GB). Is there a way to determine the 'cost' of smaller allocation sizes specifically related to seek times? Or are there any studies or articles recommending a change from the default based on this newer tech? (Assume the most average scattering of sizes program files, OS files, data, mp3s, text files, etc.)
