  • Create subdomains via C-Panel or via domain registrar?

    - by cybergeek654
    I am a novice, so excuse me if it sounds dummy. I read a few similar questions on this topic here but they did not answer my question. I have a personal website, hosted with C-panel control panel. Via C-panel I can easily create new subdomains and I do not need to apply any DNS settings or so. And the subdomian is good to go immediately and are working fine. I have unlimited subdomains option. When I check my DNS management control panel in my domain registrar's site, there is no record associated with my subdomains. Now I want to buy a new domain name from 1and1, and have it as an add-on domain in my prevouse host. 1and1 say they only allow 5 subdomains. What does this mean? Can not I create unlimited subdomains under my new domain name, just as I do for my old domain? How does C-panel create and manage subdomains that there is nothing about it in my DNS control panel? Thanks for your help

  • Unable to detect windows hard drive while running Ubuntu 12.04 from USB

    - by eapen jacob
    I am completely new to Ubuntu. I experimented with Ubuntu 12.04 by running it from a USB drive, in-order to recover files from my hard disc. History: My laptop is an IBM R60 running windows 7. Suddenly it gave me an error stating "error 2100 - Hard drive initialization error". I have read all the forums and most of them suggested that I remove and replace my HDD and that did not work. And one site suggested to try using Ubuntu to recover files. I booted my system from USB, and once Ubuntu came up, I choose "Try Ubuntu". It came up fine and I was able to surf ,and do other things, etc. I was unable to to access my files which are on the hard disc and "Attached Devices" is grayed out. 1- Is there any way to gain access to my hard disc to recover the files? How do I navigate to search for my files. 2- Is it just simply not possible if the hard disc themselves are not working? Is that why I`m unable to find the drives. I know its a very novice question, but hoping someone would help me out. Thank you, Eapen

  • Is it worth replacing mouse by standalone trackpad for heavy code-editing? [on hold]

    - by heltonbiker
    I recently got more interested in improving my tools, workspace and worflow. The first sting came with a sore finger due to a crappy keyboard, and then after some research I fell in love with the "mechanical keyboard is what you need" doctrine, bought one (cherry MX Brown if you're curious), and am very happy with the results. Currently I am replacing my previous text editor (Geany) with Sublime Text 3, and am also very happy and feeling much more powerful and professional :) Well, but while I re-read all the ancient debates about VIM vs whatever-else, the following excerpt from a blog post got me thinking again about the mouse vs keyboard, and the "moving around from the very home row" (in VIM) versus gesturing away with the tiny and unstable mouse cursor: Reaching for a mouse may indeed slow you down, but developers are commonly on machines where the trackpad is a micro-hand movement away. Most novice programmers can click on a character on screen faster than an expert Vimmer can type 20jFp; or LkEEE or /word or any other nasty way Vimmers have to use. The point of a mouse is to make arbitrary on screen jumps efficient, and it’s very good at doing that. Don’t you ever think you can beat a mouse. Well, although there is some bitterness in this statement, it makes a lot of sense, and EVEN MORE if you consider your direct input to be a TRACKPAD conveniently placed in front of your spacebar (which oddly is where I like to put my mouse, rotated 90° ccw, due to a serious tendonitis in my right shoulder, already healed, but you knod...). So, the question is: Has anyone replaced mouse by a standalone trackpad, to work in code editing in a desktop machine (that is, with a sandalone keyboard)? Was it worth the change?

  • Add & Show data in Java ArrayList [closed]

    - by Kaidul Islam Sazal
    I have a class inside a main class : static class Graph{ static int u, v, cost; } I have instantiated an arraylist of the class: static List<Graph> g = new ArrayList<Graph>(); And I insert several values into the arraylist like this: Scanner input = new Scanner(System.in); for (int i = 0; i < edge_no; i++) { Graph e = new Graph(); e.u = input.nextInt(); e.v = input.nextInt(); e.cost = input.nextInt(); g.add(e); } And I print it like this: for (int i = 0; i < edge_no; i++) { System.out.println(g.get(i).u + " " + g.get(i).v + " " + g.get(i).cost); } But the problem is that, when I print it, only the last value is shown all the time.It seems that, all the previous values are over-written with it. Input : 1 2 5 1 3 8 2 3 9 Output: 2 3 9 2 3 9 2 3 9 Expected output is just like the input.But I can't fix the problem as I am novice in java.

  • What is the best resource or method for learning more about servers and networking?

    - by kaleidomedallion
    I can get around a server to some degree, but everything I have learned has been as I have needed to learn it. Every once in a while I will learn about some new command that will revolutionize how I think about systems and networking, and realize how I could have been using it this whole time if only I had known about it. Anything to bring someone from novice to some kind of fluency? Do I just need to earn the battle scars bit by bit over the course of years? (I mean of course I do but what can I do to help it be not quite so painful?) For instance, I am still fuzzy on all of networking. Any help would be greatly appreciated.

  • How to prevent Network Manager from auto creating network connection profiles with "available to everyone" by default

    - by airtonix
    We have several laptops at work which use Ubuntu 11.10 64bit. I have our Wifi Access Point requiring WPA2-EAP Authentication (backed by a LDAP server). I have the staff using these laptops when doing presentations by using the Guest Account. So by default when you have a wifi card, network manager will display available Wireless Access Points. So the logical course of action for a Novice(tm) user is to single left click the easy to use option in the Network Manager drop down list... At this point the Staff Member (who is logged in with the guest account) expects to just be able to connect and enter any authentication details if required. But because they are using the Guest account, they won't ever have admin permissions (nor do I want them to), and so PolKit kicks in with a request for admin authorisation. I solved this part by modifying the PolKit permissions required to allow all users to create System Network Connections... However, because these Staff members are logging onto the Wifi Access Point with Ldap Credentials and because the Network Manager is now saving those credentials as a System Connection, their password is available for the next guest user session (because system connection profiles are stored in /etc/NetworkManager/system-connections.d/* ). It creates system connections by default because "Available to all users" is ticked by default when you quickly connect to a new wifi access point. I want Network Manager to not tick this by default. This way I can revert the changes I made to Polkit and users network connection profiles will be purged when they log out.

  • Template syntax for users - is there a right way to do it?

    - by RickM
    Ok, I'm in the middle of building a saas system, and as part of that, the hosted clients need to be able to edit certain layout templates, baqsically just html, css and javascript files. I'm obviously going to be wanting to use a template syntax here as it would be dumb to let people execute PHP code, so in this instance template syntax does need to be used. I know that in the grand scale of things, this is a very minor thing, but what template syntax do you use, and why? Is there one that's considered better than others? I've seen all sorts being used with no real consistency, for example: Smarty Style: {$someVar} {foreach from="foo" item="bar"} {$bar.food} {/foreach} ASP Style: {% someVar %} {% foreach foo as bar %} {% bar.food %} {% endforeach %} HTML Style: <someVar> <foreach from="foo" item="bar"> <bar:food> </foreach> PyroCMS/FuelPHP "LEX" Style: {{ someVar }} {{ foreach from="foo" item="bar" }} {{ bar:food }} {{ endforeach }} Obviously these arent 100% accurate (for example, LEX is used alongside PHP for loops), and are only to give you an example of what I mean. What, in your opinion would be the best one (if any) to go with. I ask this bearing in mind that people using this are likely to be novice users. I did look around at a bunch of hosted CMS and E-Commerce systems as these seem to make use of user-editable templates, and most seem to be using some form of their own syntax. I should note that whatever style I end up going with, it will be with a custom template handler due to the complexity of the system and how template files are stored. Plus I'd not want to touch the likes of Smarty with a barge pole!

  • Win 2008 Server configuration

    - by user123790
    Let me preface my question by saying I'm a novice in regards to server configuration. It's been 12+ years since I've attempted this. What we (our small office) are trying to achieve is to setup a Win 2008 server (located in a home) in a home network configuration (basic wireless router w/DHCP) that we (the office) can VPN to from our office. I have installed the software, installed DHCP, removed DHCP from the router, set the scope for 100 IPs and am now looking for information as to where I go from here? I believe I need to configure DNS and possibly set up static routes on the router for the home devices that need internet? The wireless clients are not receiving IPs is the current issue that I'd like to tackle. Also, would it be feasible to use the router's DHCP to assign IPs rather than having the server do it? If so, what would be the most direct way to accomplish this? I appreciate any help in this matter. Thanks

  • VPN server on Windows Server 2008 for a small office

    - by cmbrnt
    I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!

  • Computer not booting, black screen, no beeps

    - by Michael Gaddass
    I bought a pre-owned computer on Ebay. It booted fine, had to reset due to it not detecting USB mouse, but it detected the USB keyboard. Booted fine again, then I tried to install Ubuntu Desktop, when it was installing I got a phone call, when I'm answering it, I find a Blue screen of Death. I reboot the computer and nothing, no BIOS boot, no beeping, but one of the fans was on. I opened the cover and found a large amount of dust, removed it, still not booting. I'm a complete novice with computer repairs, the most advanced thing I did was take a 286 harddrive and replace a 486's damaged harddrive with it (put the drive into the 486 that is), what could possibly be causing this?

  • Munin help... configure graphs to show different time periods

    - by PiZzL3
    I'm running a server with Munin installed through WHM cPanel. I've been googling around and I can't seem to find out how to do the following: A: Change a graph to show a different time period (currently I can only view, day, week, month, year). I would like to possibly view per minute, per hour... or specific intervals such as per 30 minutes, per 4 hours, etc... B(optional, but preferred): Add new graphs with the above criteria(A) above. I am a novice with all things that will possibly be required to do this (such as ssh). I wish I could just go edit a php file as I'm highly experienced in that subject. Thanks for any help!

  • a friendly elaboratation on how iceweasel misses as recent request was discovered in post tut

    - by v3x3n
    I would like to specify what you asked about in how iceweasel misses on in hopes that you are interested in considering the answer to be valid considering the package should run efficient to a novice user especially when getting a first impression on a new software, browser, or package they are given by default. First let me say that I am very grateful for all debian has and continues to do for its user base and I am not complaining, only hoping that in mentioning such it will eventually aid in improving the disappointing experience iceweasel gave me in multiple ways right from the start of using it. I am sure tremendous amounts of hard work went into making it work as well as it does, and tremendous effort continues to go into IW like the rest of the package and distros such as this... Having said that, I do aim to keep my examples simple as possible but also explained in enough detail as to not leave out important info to get a full idea of my issue... (Thanks for understanding if I sound novice to debian, I am but continue to learn and advance by trial and error each day, and of course the wonderful help from all the great minds available here and there)... Well, my bone to pick (unfortunately as I disdain being a complainer when so much has been done for us, the end user) with IW is mainly 3 immediately noticed problems in offering me a smooth test drive (completely normal browsing conduct of your average user, I should indicate) as soon as I started out a task using IW (heading directly to google images and searched for a few web sized images, then saved a few (no more than 800 to 900 in dimensions, typically a normal procedure I would imagine) I experienced a horrendous reoccurring freeze and lag time that almost left me to kill the process more than once on each attempt and continued to compound so that by a few attempts later, even 1 single image save locked up the entire browser, ultimately giving up on my procedure in its simplicity with a bit of aggravation, if there was something I had done wrong on my end pre-attempt or during installation. Secondly, visiting video player sites in this case youtube will not allow for any video feed to play whatsoever and again, experienced a slight freezing that eventually dissipated as long as I didn't attempt to press play or reload another video trial... Very annoying and possibly related to my first issue (which could rely on my own lack of knowledge in setup config, but that troubles me if so).... Lastly as another user has stated already, in which brought you to ask them what exactly seemed to be the problem in the first place is also my final straw that broke the weasel's back, leading me here to find a solution to a updated version of firefox... being that iceweasel (an apparent build of firefox 17.x.x) leaving the user to find themselves out of luck when installing their favorite or much useful add-ons or plugins that aid their task or normal usage online.... As the other user clearly stated... there is almost zero options and barely any luck to find compatible plugins with such an outdated version still being used... I can only imagine if as a novoice or standard user to linux... and beginner to debian (which I am all for btw!) if I am discovering major conductivity issues which hinder normal user conduct right off the bat... that there is probably a bundle or more of security vulnerabilities that would unravel to me if I continued to give mr Hommey's package any further attention, or interest in continuing to use... This is a deal breaker on any account, unless all 3 of these issues stated are due to a very n00berish setting or lack thereof (which if that is the case, such was not properly stated for beginner in any place available by following installation tutorials such as LVM installers, which I felt lacked a clear understanding to someone who is trying to learn why and how, rather than, a fix to a potentially broken out of box installation... I really think that is irrelevant in any case however, as there is much step by step support regarding that kind of thing, just saying... its very challenging, along side a job to keep deadlines on, and the need to learn a better and more costomizible system, that was not as popularized when I became a dev via windows (OK OK I know thats a huge mistake and now I am way off original topic but anyway) Thanks very much for taking the time to read over this, and I hope it honestly gives you a few good and valid reasons for users wanting and seeking a way to get around iceweasel altogether... Finally, if I am missing something vital that renders all I've stated invalid or useless, please feel free to shove that elephant in the room my direction! Thanks for all you do, as I am sure it is very useful and dedicated, being you are a debian maintainer, and super user! Much love for intelligence, freedom and sharing the secrets of the web! May it remain unregulated and a good place to grow and learn for generations to come! Stay true! Take care now! -v3x (v3x @ gmx .com)

  • How to set up strongswan or openswan for pure IPSEC with iPhone client?

    - by Shabbyrobe
    I'm having trouble finding concrete, up-to-date information for how to set up strongswan or openswan to be used by the iphone's VPN client. My server is behind a budget linksys NAT router. I found this, but it mentions a whole bunch of .pem files with no reference for how to create them. Unfortunately, the "fine" manuals for both packages were quite inscrutable and unfriendly to a novice. I've set up OpenVPN before and managed to get serviceable results very quickly, but after a day and a half of reading out of date docs, I barely even know where to start. Any help would be greatly appreciated!

  • From release to business

    - by geneotech
    So let's say that I've finished programming a simple, indie MMO game similiar to Tibia. I've got a stable server application that is ready to launch, i've got a tested bug-free working client application that is ready to play and the game's official website (ready to host) with payment system and client that is ready to download for free. Let's say none of them break copyright laws, and no matter how impossible it sounds, let's for now say it's true. My game divides accounts into two groups - free and premium. If someone gets premium, he's granted access to all possible game features, that of course, need server authorisation to work properly. Let's say that the "premium account" can be bought on the website for a fixed money/month. Free accounts mean that everyone can actually play, but without paying, you get limited access. This is what the mentioned payment system will be for. Well, I'm completely novice to these business entities issues, so in short: what, in terms of law, are steps from here to the state where my game earns money in a fully legal way ? Also, is there for example, something like verification if game gives the user what it actually offers when paying on its website ? I live in Europe, if it changes something.
