  • NetDiag + TCP Blocking?

    - by CrazyNick
    We are facing some issue with the sharepoint 2007 timer jobs everyday at a specific time, so decide to track the tcp blocking informartion during those hours using NetDiag tool. We are not able to find the required information if we uses "netdiag /test:ipsec", what is the command that can be used to pull the TCP blocking information and how to configure it? if i ran the command "netdiag /test:ipsec /debug" it is returning "IP Security test . . . . . . . . . : Skipped", what does it mean?

  • Need to move a debian server from i686 to x86_64 architecture

    - by user64204
    I have a debian server that I need to move from one hosting provider to another. I don't really know how the old server was setup, all I know is that it's running a Ruby on Rails application with a lot of custom libraries installed and that I should prepare myself for a painful migration. Old server: -os: debian 5.0.9 -used disk space: 3.2GB -architecture: i686 New server: -os: debian 5.0.9 -free disk space: 10GB -architecture: x86_64 As you can see the problem is that the servers are running different architectures. Q: Is there anyway I could somehow migrate the old to the new server in a few steps (or am I just dreaming I could) ? I was thinking maybe I could: -get list of packages and gems installed on old server and use for loop to install them all on the new -copy the disk content from old to new server while excluding what is architecture-specific (the problem is that I don't really know what to exclude).

  • public_html permissions for local development

    - by maGz
    I know this question has popped up a couple times, but I can't seem to find a definitive answer to my issue, so please bear with me. I have Ubuntu Server 12.04 setup in VirtualBox for PHP development and testing (Drupal plus other PHP sites using Yii framework). My question is in 3 parts... 1) If I create a public_html folder under /home/myuser, do I need to give ownership of that folder to the Apache www-data group? If so, are there any specific permissions I should be setting? 755? (Btw, I am following this guide to create the public_html directory and set up multiple virtual hosts per site I create and test) I previously had all of my sites under /var/www, but ran into massive permission denied errors whenever I tried to sFTP to it, either through FileZilla or PhpStorm. This is what I had previously done: sudo chgrp www-data /var/www sudo chmod -R 775 /var/www sudo chmod -R g+s /var/www sudo usermod -G www-data [my_ftp_user] 2) The second part of my question is this: If I create my PHP project and files in Windows through PhpStorm, and then upload via sFTP, will permissions get affected? 3) Once I am satisfied with my developed project, would it be advisable to move and test them under /var/www to see how it would fair in a production-ish environment? I would really appreciate the help and advice here. I'm learning more as I go along, but dealing with Linux files and permissions is a bit of a new ballgame for me! Thank you

  • What relational database system should I learn? [closed]

    - by acidzombie24
    At the moment i know sqlite (my favorite), mysql (its ok, i get annoyed) and i do not want to learn ms/t sql (it only allows one nullable row if the column is unique). I am thinking about learning a new database system. My requirements for it is Must allow multiple connections at once (read and write) All or data i choose must be ACID compliant Performance should be good. I have a 17gb table in one project. It should perform well on read and transactional writes. With mysql it took hours to restore it and there were no foreign keys on that specific table. It only finished in a workday because i found a suggestion to adjust a setting which i think was key-buffer. And it still took hours Unique columns that allow more then one row to be null. I shouldn't have to say it but dammit MS. Allows one to make ongoing backups. Something like 'binary logs'. Some relatively small amounts of data i can grab and apply it to my local db to have it in sync with the one on the server. Table joins. I rather not write a bunch of queries to simulate a join What I would like but is not required Foreign keys. This may be a requirement later Open sourced Fair tool support. So i can measure queries, easily backup/restore, etc .NET and C (or C++) interface. (I seen one that uses raw tcp with JSON which was okish) Good subquery support. Once i was working with an older version of mysql (i believe <5.1 but it could have been 5.1) and i had to write many queries to do one query because it couldn't do subqueries. Or maybe it couldnt do it efficiently and died bc of memory limitations with a huge dataset. What db system should i learn?

  • IP-restricted port forwarding with iptables

    - by Tom
    For an example, I have two authorized client computers, 1.1.1.1 and 2.1.1.1. My server running iptables is 3.1.1.1 and my firewalled web server is 4.1.1.1. When one of the authorized client IPs connects to 3.1.1.1 on port 80, I would like the connection to be forwarded to 4.1.1.1 on port 8888. If any other IP attempts to connect I would like it to refuse/drop the connection. What iptables config would accomplish this? Is there something more specific out there that would be better suited for this job?

  • Trying to make a game with C++, using lists to store bullets and enemies, but they are not erased

    - by XD_dued
    I've been trying to make a pretty simple space shooter game with C++, and I have been having a lot of trouble trying to use lists to store enemies and bullets. Basically I followed the post here almost exactly to store my bullets: SDL Bullet Movement I've done something similar to store my enemies. However, when I call bullets.erase(it++), for some reason the bullet is not erased. When the bullet movement is run for the next frame, it tries to re delete the bullet and segfaults the program. When I comment out the erase line, it runs fine, but the bullets are then never erased from the list... Is there any reason why the elements of the list aren't being deleted? I also set it up to print the number of elements in the list for every iteration, and it does not go down after deleting. Thanks! EDIT: Here's the specific code I'm using to store my enemies and having them act: std::list<Grunt*> doGrunts(std::list<Grunt*> grunts) { for(std::list<Grunt*>::iterator it = grunts.begin(); it != grunts.end();) { if((*it)->getHull() == 0) { delete * it; grunts.erase(it++); } else { (**it).doUnit(grunts, it); ++it; } } } Grunt is my enemy class, and the list grunts is a global variable. Is that my problem? When I pass the global into the function it becomes local? I assumed lists would be a reference type so thought this wouldn't be a problem. Sorry if this was a dumb question, I'm very new to C++, this is the first major thing I'm working on.

  • SharePoint 2010 MySites - Simple explanation needed!

    - by Chris W
    I've been playing around with the 2010 beta for a couple of weeks, experimenting with topology options etc. I think I've got myself totally confused as to how it works hence if there's any SP experts out there that can explain things in simple terms for me I'd appreciate it! I want to setup a farm with 3 servers providing the content & MySites. I presume that the way to do this is to load balance or DNS round robin traffic between the 3 servers. The bit where I'm confused is that My Site Settings page asks for a specific My Site Host hence all my site traffic will be pushed to a single server even though we have 3 in the farm. If this hosts fails I presume MySites will be unavailable. Is this right? How do I configure it so that access to MySites is load balanced across the 3 servers in the farm?

  • View the Time & Date in Chrome When Hiding Your Taskbar

    - by Asian Angel
    Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

  • Is there a shell-independent HUD-like menu search tool for Gnome?

    - by Redsandro
    The Ubuntu HUD - you love it or you hate it. Personally I rather like a classic desktop, so I use Xfce and Cinnamon, and I don't want to lose my menu in applications. But the HUD is pretty awesome when your menus are complex and you forgot where an option sits. This makes that search trick very interesting. I know the HUD is Unity specific. I am looking for a HUD-like tool to complement the menu in shells other than Unity. There is Appmenu Runner for KDE that does this. There is also appmenu-qt for KDE. Problem with the above is that it uses KDE libs, and it only works for KDE apps. This is Linux, there aught to be something like this for GNOME/GTK apps, right? Looking for any tool that can search the menus. I already use(d) Kupfer and Gnome-do, something like that would suffice if only it includes searching the menus for the currently focussed application.

  • What to learn after standard C++?

    - by Luca Cerone
    I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

  • Automatically Connecting to Hidden SSID WiFi Network

    - by Zack
    My MacBook Pro will not automatically connect to a Wireless network with a hidden SSID. It makes me select the "Join Other Network..." in the Airport menu (in the system tray), where I need to input the name of the network, then security type, password and wait for it to connect. This is becoming increasingly annoying to have to do every time I come back to my desk. I'm running Mac OS X 10.5 and there doesn't seem to be an option to connect to a specific network, but rather "Preferred Networks." The only network I have set as Preferred that's in range is my home network, and it still doesn't automatically connect. Making the network publicly visible isn't under my control, so I'm stuck with what's currently in place. Reader's Digest version: How do I make my MacBook Pro automatically connect to a WiFi Network with a hidden SSID without having to "configure" it every time I want to connect?

  • Is there any way to prevent a Mac from creating dot underscore files?

    - by SoaperGEM
    At work we're letting one of our very tech savvy clients actually help out a little with a few development projects specific to him. However, he uses his own personal Macbook, and as he edits files on our (Windows) networks, his Macbook always creates a bunch of unnecessary meta files that we end up deleting later. For instance, it creates a file called .DS_Store in any directory he opens, as well as "dot underscore" files for each file he edits. So for instance, if he's editing a file called "Main.php", his Macbook will create another file called "._Main.php". I know there are ways to prevent creation of .DS_Store files, but none about how to prevent creation of these hidden files prefixed with dot underscore. Is there any way to turn that off on Macs? Any way to prevent it from creating those files in the first place?

  • Preventing my postfix to send my local users spam

    - by Jack
    I have a postfix/dovecot mail server with 100 different users. When they send an email they need to be authenticated. I successfully use saslauth to achieve this. Few days ago I had a problem. One specific user, probably with a virus or a spam-bot installed in its computer, started to send out through my server thousands of emails in few hours. As result, my ip has been blocked by many isp provider (@aol, @yahoo, and others) and has been listed in many blacklist, making all my 100 users unable to send any email to anyone. What is the best practice to avoid this problem? It would be great if my server could recognize a spamming user and automatically block it. Also, have a limit of, say, 30 emails per hour could be a partial solution. Any idea how to face this problem? Thank you

  • Trouble "turning off" dialtone in Exchange 2010

    - by makerofthings7
    Given that there are two ways to enable dial tone, I'm having trouble turing it off. The two ways I'm aware of are: Dismount the database, delete it or rename it, mount it, Exchange will prompt for a dial tone creation. Run the command: Get-Mailbox -Database DB1 | Set-Mailbox -Database DTDB1 as described here Both options should result in Outlook "thinking" it's in dial tone mode. Since my goal is to shut off dial tone, I think I need to learn the specific, technical parameters that "tell" Outlook that it is in dial tone mode. Question How can I turn off dial tone for a given database? What tells outlook that it's in dial tone mode?

  • How to know how much detailed requirements should be?

    - by user1620696
    This doubt has to do with the requirements gathering phase of each iteration in one project based on agile methodologies. It arose because of the following situation: suppose I meet with my customer to gather the requirements and he says something like: "I need to be able to add, edit, remove and see details of my employees". That's fine, but how should we register this requirement? Should we simply write something like "the system must allow the user to manage employees", or should we be more specific writing for points The system must allow the user to add employees; The system must allow the user to see details of employees; The system must allow the user to edit employees; The system must allow the user to delete employees; Of course, this is just an example of a situation I was in doubt. The main point here is: how to know how much detailed I must be, and how to know what I should register? Are there strategies for dealing with these things? Thanks very much in advance!

  • Host a Debian repository on a Windows Web/Ftp server

    - by Dave
    At the risk of causing a matter vs. antimatter paradox that would end the world as we know it ... Is it possible to host a Debian repository on a Windows server? We have some applications which are available for Windows, Mac OS X, and Linux. Our web site, from where the application can be downloaded, is a Windows Server 2008 box running IIS 7. That is not going to change, and I would like to avoid having to purchase another server and/or domain. I would like to take advantage of the Debian packaging system so that I can just instruct users to add our repository to their software sources, and then they can install, get updates, resolve dependencies (some of which are not yet in the stable/main distributions of my target platforms), etc. The instructions I can find on the internet require linux-specific tools to create a local repository, but are unclear as to whether or not that can be copied to an FTP site as is, or if it requires some local daemons to be running or something.

  • Network Block Device (NBD) clients for Windows or similar solutions

    - by przemoc
    Are there any NBD clients for Windows? Strangely, I cannot find any, or I am searching for them in a wrong way. Such client should be possibly a driver with front-end tool (may be a command-line one) allowing to create virtual drives and associate them with given hosts (or simply localhost) and ports where NBD servers are listening. From user perspective virtual drive should be close to what physical drive is, so it should be accessible as something like \\.\PhysicalDriveX (maybe \\.\VirtualDriveX?), be visible in Disk Management (diskmgmt.msc) and mountvol tools at least. (The only thing I found remotely close to NBD on Windows is ImDisk's proxy mode and companion tool devio, but AFAIK ImDisk only works at partition level (so no virtual drive) and devio uses different protocol.) Secondary question is: Are there any (preferably simple) Windows-specific solutions allowing creation of virtual drive delegating read/write request to user-space via some explicit way (like via TCP, IPC, DLL implementing given API, etc.)?

  • Resume on 30 Days of SharePoint

    Dear readers, as you might have noticed... It was an organisational desaster on my end! Even though I continued my studies and research on Microsoft SharePoint 2013 during the last 30 days, I wasn't able to write an article a day to keep you posted on my progress. Nonetheless, I gathered a good number of additional blogs, mainly SharePoint MVP sites, and online forums which will be helpful in the next couple of weeks while I'm actually going to develop a C#-based client which will enable an existing 'legacy' application to SharePoint as a document management system (DMS) besides other already existing solutions. Finding excuses Well, no. Not really. I simply didn't block any or enough time every day to write down my progress during my own challenge. My log book on learning about SharePoint stands at 41 hours and 15 minutes during this month. Which means that I spent an average of more than 1 hour per day on getting into SharePoint. I know that might sound a little bit low but also keep in mind that I went for the challenge on top of my daily job and private responsibilities. During the same period there had been two priority 0 incidents from clients - external root cause - which took presedence over this leisure project. More to come Anyway, it was a first trial and despite the low level of reporting on my blog, I'm confident about what I learned during the last 30 days, and I'm ready to implement the client's requirements. At least, I would say that I have a better understanding about the road map or the path to walk during the next month. As time and secrecy allows I'm going to note down some bits and pieces... During the process of development, I'm going to 'cheat' on the challenge summary article and add links to those new entries. Just for the sake of completeness. Next challenge? Hmm, there had been ideas during the last meetup of the Mauritius Software Craftsmanship Community (MSCC) regarding certifications in IT and eventually we might organise some kind of a study group for specific exams, most probably Microsoft exams towards MCSD Web Developer or Windows Developer.

  • Firefox loses app tabs when I shut down my computer sometimes

    - by Xitcod13
    When I shut down my computer sometimes my app tabs do not reopen in Firefox and I need to remake all of them which is pretty annoying. I don't know if this is a common bug it might be specific to my computer. I run Vista x64 and it just seems to still have quite a bit of problems. Sometimes when I command it to shut down it does not simply showing shut down loading for hours so I need to manually turn it off. I think that might be messing up Firefox but I'm not sure. I also found a related thread on Bugzilla about this problem but I don't think it's the same issue as it only happens when I shut down my computer.

  • Set Up Port-Forwarding on Netgear N300 Router

    - by Smitty
    I have a Netgear N300 router that has DynDNS.org as a preset DDNS option. After setting it up it (unsurprisingly) sent traffic directly to my router. I'm essentially using this to connect remotely to my home (virtual) machine/s. From what I've read, it seems like I need to set up port forwarding. I tried forwarding "all" inbound traffic to a specific IP but that just didn't work. What am I doing wrong? Also, I just noticed I get this error after applying the settings: "The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type"

  • How can I check myself when I'm the only one working on a project?

    - by Ricardo Altamirano
    I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).

  • Upgrading to 12.10 on an external hard drive

    - by Tom Childers
    I did some googling on this and didn't find anything specific for my situation. I currently have 12.04 installed on an external USB hard drive. It's working great. I want to upgrade it to 12.10. My bandwidth is very limited so I have a friend who will download 12.10 for me and put it on a flash stik. Then I can upgrade without having to do the download myself. Which particular version of the 12.10 download file(s) should I get? Are there alternate 12.10 downloads that have all the packages? How do I set it up so when I upgrade 12.04 I can specify that it look in some local repository for the 12.10 files? Can I just dump the 12.10 files in some local directory? Or do I have do go thru some complex commands to create a local repository? I'm pretty new to Linux so a long process of complex terminal commands will probably be a show stopper for me. Remember that my 12.04 install resides on an external hard drive. And I have a laptop with multiple USB ports. Thanks! Advait

  • How do you compare programming job offers from companies in different countries?

    - by Danny Tuppeny
    This isn't really a programmer-specific question, but I'm not sure of a more appropriate place, and I think the users of this site are best able to answer the question in the context of programmers. Relocating to the US seems fairly common in the programming industry. I live in the UK, and maybe one day, I might do it too. So, if that day comes - how would you go about comparing job offers? Benefits are fairly easy to compare, but given the differences in cost of living, how would you go about comparing salaries and the quality of living you'll have? In a country where the cost of living is lower, you might be able to accept a lower salary (based on exchange rate) and still have the same quality of living. But what can you do to ensure this? In some cases, you may even take a "pay rise" in terms of exchange rate, but end up far worse off. How can you compare job offers across different countries to get an idea of the salary you would need in order to not feel you've gone "backwards"?

  • rsync server side limit bandwidth/connection

    - by c2h2
    In a VOIP application, I have upto 3000 clients rsync audio files from there linux server in a daily, server is placed at a data center (10Mbps in/out bound), the server works as a VOIP sip server running FreeSWITCH (low ping latency should be ensured.) Therefore I would like to have server side control of rsync which controls: Limit total outbound bandwidth. Limit total number of connections. (Reject clients while at max number of connection and let it retry after a specific time frame.) OPTIONAL: list/kill individual connections. Normally I would use ssh + rsync + pem_keys with some extra options, but above requirements are not feasible by simple command lines. Can anyone point me some direction. or show some scripts/tools? I would also probably integrate them and release on github. Thanks!
