  • How to make local apache server public/visible ? [closed]

    - by George
    Hello. I am running an Apache2 server on a Fedora 13. I'd like to make it publicly accessible(visible).For example I'd like when somebody types http://my.ip.numbes/ that they would see what I have in my document root folder. Just for a presentation of a course work at university. Permissions are set to 755. User owning the document root is apache. SELinux is temporarily disabled. But port 80 is closed. I tried to open it by adding an entry to iptables and restarting them, no change. I guess I am missing something big here. Help would be greatly appreciated.

  • How to debug a server that crashes once in a few days?

    - by Nir
    One of my servers crashes once in a few days. It does low traffic static web serving + low trafic dynamic web serving (PHP, local MYSQL with small data, APC, MEMCACHE) + some background jobs like XML file processing. The only clue I have is that a few hours before the server dies it starts swapping (see screenshot http://awesomescreenshot.com/075xmd24 ) The server has a lot of free memory. Server details: Ubuntu 11.10 oneiric i386 scalarizr (0.7.185) python 2.7.2, chef 0.10.8, mysql 5.1.58, apache 2.2.20, php 5.3.6, memcached 1.4.7 Amazon EC2 (us-west-1) How can I detect the reason for the server crashes ? When it crashes its no longer accessible from the outside world.

  • Lazy HTML attributes wrapping in Internet Explorer

    - by AGS777
    Having encountered this Internet Explorer (all versions) behavior several times previously, I eventually decided to share this most probably useless knowledge. Excuse my lengthy explanations because I am going to show the behavior along with a very simple case when one can come across it inadvertently. Let's say I want to implement some simple templating solution in JavaScript. I wrote an HTML template with an intention to bind data to it on the client side: Please note, that name of the “sys-template” class is just a coincidence. I do not use any ASP.NET AJAX code in this simple example. As you can see we need to replace placeholders (property name wrapped with curly braces) with actual data. Also, as you can see, many of the placeholders are situated within attribute values and it is where the danger lies. I am going to use <a /> element HTML as a template and replace each placeholder pattern with respective properties’ values with a little bit of jQuery like this: You can find complete code along with the contextFormat() method definition at the end of the post. Let’s assume that value for the name property (that we want to put in the title attribute) of the first data item is “first tooltip”. So it consists of two words. When the replacement occurred, title attribute should contain the “first tooltip” text which we are going to see as a tooltip for the <a /> element. But let’s run the sample code in Internet Explorer and check it out. What you’ll see is that only the first word of the supposed “title” attribute’s content is shown. So, were is the rest of my attribute and what happened? The answer is obvious once you see the result of jQuery(“.sys-template”).html() line for the given HTML markup. In IE you’ll get the following <A id={id} class={cssClass} title={name} href="{source}" myAttr="{attr}">Link to {source}</A> See any difference between this HTML and the one shown earlier? No? Then look carefully. While the original HTML of the <a /> element is well-formed and all the attributes are correctly quoted, when you take the same HTML back in Internet Explorer (it doesn’t matter whether you use html() method from jQuery library or IE’s innerHTML directly), you lose attributes’ quotes for some of the attributes. Then, after replacement, we’ll get following HTML for our first data item. I marked the attribute value in question with italic: <A id=1 class=first title=first tooltip href="first.html" myAttr="firstAttr">Link to first.html</A> Now you can easily imagine for yourself what happens when this HTML is inserted into the document and why we do not see the second (and any subsequent words if any) of our title attribute in the tooltip. There are still two important things to note. The first one (and it actually the reason why I named the post “lazy wrapping” is that if value of the HTML attribute does contains spaces in the original HTML, then it WILL be wrapped with quotation marks. For example, if I wrote following on my page (note the trailing space for the title attribute value) <a href="{source}" title="{name}  " id="{id}" myAttr="{attr}" class="{cssClass}">Link to {source}</a> then I would have my placeholder quoted correctly and the result of the replacement would render as expected: The second important thing to note is that there are exceptions for the lazy attributes wrapping rule in IE. As you can see href attribute value did not contain spaces exactly as all the other attributes with placeholders, but it was still returned correctly quoted Custom attribute myAttr is also quoted correctly when returned back from document, though its placeholder value does not contain spaces either. Now, on account of the highly unlikely probability that you found this information useful and need a solution to the problem the aforementioned behavior introduces for Internet Explorer browser, I can suggest a simple workaround – manually quote the mischievous attributes prior the placeholder pattern is replaced. Using the code of contextFormat() method shown below, you would need to add following line right before the return statement: result = result.replace(/=({([^}]+)})/g, '="$1"'); Below please find original sample code:

  • Exchange with Evolution or any other mail client

    - by Oscar Godson
    I see other questions about this, no answers and no one with a completely similar question. I work for a place with an Exchange 2007 server. There is an http://owa.ourserver.com that is accessible from anywhere. I've tried every combo I can think of for Evolution - Microsoft Exchange, including the MAPI plugin, but then I read that, that doesn't work on OWA Exchange email servers and I can't get it to connect at all that way. If there is no way to connect via Evolution, is there another mail client? I tried Thunderbird, but I couldn't get it to work with Exchange either...

  • Disable incognito in chrome or chromium

    - by TheIronKnuckle
    I'm addicted to certain websites to the point where it's interfering with my life regularly and sick of it. I want to install website blockers that aren't easy to circumvent. In Chrome, incognito mode is easily accessible with a ctrl-shift-n. That is ridiculous. Whenever I feel an urge to go on an addictive website, it doesn't matter what blockers and regulators I've got installed; three keys can get round them in a second. Simply uninstalling chrome isn't an option either, as it's way too easy to sudo apt-get install it right back. So yes, I want to disable incognito mode completely (and if possible making it totally impossible to get it back). I note that some guy has figured out how to do it on windows with a registry entry: http://wmwood.net/software/incognito-gone-get-rid-of-private-browsing/ If it can be done on windows it can be done on ubuntu!

  • How to create a restricted SSH user for port forwarding?

    - by Lekensteyn
    ændrük suggested a reverse connection for getting an easy SSH connection with someone else (for remote help). For that to work, an additional user is needed to accept the connection. This user needs to be able to forward his port through the server (the server acts as proxy). How do I create a restricted user that can do nothing more than the above described? The new user must not be able to: execute shell commands access files or upload files to the server use the server as proxy (e.g. webproxy) access local services which were otherwise not publicly accessible due to a firewall kill the server Summarized, how do I create a restricted SSH user which is only able to connect to the SSH server without privileges, so I can connect through that connection with his computer?

  • Unobtrusive Maximum Input Lengths with JQuery and FluentValidation

    - by Steve Wilkes
    If you use FluentValidation and set a maximum length for a string or a maximum  value for a numeric property, JQuery validation is used to show an error message when the user inputs too many characters or a numeric value which is too big. On a recent project we wanted to use input’s maxlength attribute to prevent a user from entering too many characters rather than cure the problem with an error message, and I added this JQuery to add maxlength attributes based on JQuery validation’s data- attributes. $(function () { $("input[data-val-range-max],input[data-val-length-max]").each(function (i, e) { var input = $(e); var maxlength = input.is("[data-val-range-max]") ? input.data("valRangeMax").toString().length : input.data("valLengthMax"); input.attr("maxlength", maxlength); }); }); Presto!

  • Ubuntu 12.04 graphics crashing when GVIM opens TEX files

    - by Pdp Molniya
    I am having a little problem everytime I open GVIM to edit *.TEX files.... the menus die, windows jiggle (maximize and minimize quickly) and I get a 'internal error ' crash report from ubuntu (12.04).

  • How to use rel=canonical with Sitecore aliases?

    - by Mike G
    I have inherited a Sitecore architecture that is a mess from an SEO duplicate content POV. There are multiple aliases that have been created (and indexed by the search engines) for many of the 2nd tier pages of the site. Due to server issues, I am not able to 301 redirect these duped pages, so I would like to use the rel=canonical tag in an attempt to try and get Google/Bing to recognize the correct pages I would like to appear in the index. I have blocked the most extraneous duped pages with a robots.txt file, however, since Google/Bing have already spidered many of the duped pages, I need to keep them accessible to the spiders, BUT removed from the index. The catch is, since the duped pages are aliases (and don't really physically exist in Sitecore that I can find), I am not sure how to go about using rel=canonical - or if I even can in this situation..?

  • Empathy auto accept group chat invite

    - by Sivaji
    I'm using empathy 2.34.0 as chat client for account hosted on Google app (server talk.google.com). I'm happy with the features that empathy provides and integration with Google chat, however for group chat when the request is received I need to click on "join" button showed in popup to get started. This makes sense but I would to know if there is any way to automatically join the chat room without clicking the "join" button as I use it only with trusted uses. Besides the messages shared after the invite request and before my entry to chat room is not accessible to me. I looked around the empathy settings but couldn't find anything useful, wondering if I can get some help from here. Thanks.

  • Execute a Managed bean from a JSF view in WEB-INF folder

    - by JonathanVila
    We are initiating in Spring + Primefaces development and the first problem we have encountered is about storing the xhtml pages into the WEB-INF folder. When we use a faces form in a view located inside the WEB-INF folder, then the commandButton does not execute the managed bean method. Our bean : In fact we think the problem is that with JSF , the pages are rendered using a link to the same page as the action of the form, so if the page is located in WEB-INF it is not public accessible. We know that having all our xhtml views in the web folder instead of WEB-INF actually solves the issue, but we would like to store that pages into WEB-INF. Thank you.

  • Content in Context: The right medicine for your business applications

    - by Lance Shaw
    For many of you, your companies have already invested in a number of applications that are critical to the way your business is run. HR, Payroll, Legal, Accounts Payable, and while they might need an upgrade in some cases, they are all there and handling the lifeblood of your business. But are they really running as efficiently as they could be? For many companies, the answer is no. The problem has to do with the important information caught up within documents and paper. It’s everywhere except where it truly needs to be – readily available right within the context of the application itself. When the right information cannot be easily found, business processes suffer significantly. The importance of this recently struck me when I recently went to meet my new doctor and get a routine physical. Walking into the office lobby, I couldn't help but notice rows and rows of manila folders in racks from floor to ceiling, filled with documents and sensitive, personal information about various patients like myself.  As I looked at all that paper and all that history, two things immediately popped into my head.  “How do they find anything?” and then the even more alarming, “So much for information security!” It sure looked to me like all those documents could be accessed by anyone with a key to the building. Now the truth is that the offices of many general practitioners look like this all over the United States and the world.  But it had me thinking, is the same thing going on in just about any company around the world, involving a wide variety of important business processes? Probably so. Think about all the various processes going on in your company right now. Invoice payments are being processed through Accounts Payable, contracts are being reviewed by Procurement, and Human Resources is reviewing job candidate submissions and doing background checks. All of these processes and many more like them rely on access to forms and documents, whether they are paper or digital. Now consider that it is estimated that employee’s spend nearly 9 hours a week searching for information and not finding it. That is a lot of very well paid employees, spending more than one day per week not doing their regular job while they search for or re-create what already exists. Back in the doctor’s office, I saw this trend exemplified as well. First, I had to fill out a new patient form, even though my previous doctor had transferred my records over months previously. After filling out the form, I was later introduced to my new doctor who then interviewed me and asked me the exact same questions that I had answered on the form. I understand that there is value in the interview process and it was great to meet my new doctor, but this simple process could have been so much more efficient if the information already on file could have been brought directly together with the new patient information I had provided. Instead of having a highly paid medical professional re-enter the same information into the records database, the form I filled out could have been immediately scanned into the system, associated with my previous information, discrepancies identified, and the entire process streamlined significantly. We won’t solve the health records management issues that exist in the United States in this blog post, but this example illustrates how the automation of information capture and classification can eliminate a lot of repetitive and costly human entry and re-creation, even in a simple process like new patient on-boarding. In a similar fashion, by taking a fresh look at the various processes in place today in your organization, you can likely spot points along the way where automating the capture and access to the right information could be significantly improved. As you evaluate how content-process flows through your organization, take a look at how departments and regions share information between the applications they are using. Business applications are often implemented on an individual department basis to solve specific problems but a holistic approach to overall information management is not taken at the same time. The end result over the years is disparate applications with separate information repositories and in many cases these contain duplicate information, or worse, slightly different versions of the same information. This is where Oracle WebCenter Content comes into the story. More and more companies are realizing that they can significantly improve their existing application processes by automating the capture of paper, forms and other content. This makes the right information immediately accessible in the context of the business process and making the same information accessible across departmental systems which has helped many organizations realize significant cost savings. Here on the Oracle WebCenter team, one of our primary goals is to help customers find new ways to be more effective, more cost-efficient and manage information as effectively as possible. We have a series of three webcasts occurring over the next few weeks that are focused on the integration of enterprise content management within the context of business applications. We hope you will join us for one or all three and that you will find them informative. Click here to learn more about these sessions and to register for them. There are many aspects of information management to consider as you look at integrating content management within your business applications. We've barely scratched the surface here but look for upcoming blog posts where we will discuss more specifics on the value of delivering documents, forms and images directly within applications like Oracle E-Business Suite, PeopleSoft Enterprise, JD Edwards Enterprise One, Siebel CRM and many others. What do you think?  Are your important business processes as healthy as they can be?  Do you have any insights to share on the value of delivering content directly within critical business processes? Please post a comment and let us know the value you have realized, the lessons learned and what specific areas you are interested in.

  • Reboot to fail safe mode when root file system is full

    - by Richard
    I have a system running on a 4GB Nandrive. When the drive is full, Ubuntu will not boot :( and I have to plug in a rescue thumbdrive to delete files. The problem is the hardware is not easily accessible except via network. Is there a sure-fire way to boot Ubuntu, say, to RAM or other means when the disk is full or on any other errors in the normal boot process? In other words, is there a fallback rescue boot mode with networking? Thanks for any advice.

  • If my URL's are static, but then parsed by Javascript, does that make it crawlable?

    - by Talasan Nicholson
    Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?
