• Apache configuration file visualization/testing

  - by Matt Holgate

  Is there a tool available (or a debug mode built into Apache) that will allow me to interactively test and explain an Apache configuration for a given request? In particular, I'd like to be able to see which directives will apply when requesting a specific URL. For example, the output for the URL http://myserver.com/foo/bar/bar.html might look something like: Allow from 192.168.0.3 <-- From <Location /foo/bar> in myserver.com vhost Require valid user <-- From <Directory /var/www/foo> in global configuration Satisfy any <-- From <File bar.html> in global configuration [Background: why do I want this? The apache merging rules for configuration directives are quite complex to get right. It would be great to have a tool which allows you to check that your rules are doing exactly what you want, and would be a good learning tool]. If there isn't such a tool, is there a debug option in Apache that will log such information for each incoming request?

• Display "iftop" on web

  - by DmitrySemenov

  I do iftop -i eth1 > out.txt It does produce the file with "encrypted" UI content such as [(B[)0[[1;80r[[mO[[?7h[[?1h[=[[H[[J[[0;7mO Listening on eth1 [[1;48H[[mO12.5Kb Is it possible to display this as a web xhtml output somehow? cat out.txt on my console does produce a normal iftop window but when I do the same thing over the web I get the content above. I understand that it is "managed" on kernel level. Is the task that I want to perform possible?

• how to copy the results from a grep command to the bash clipboard?

  - by avilella

  If I type something in a Linux bash terminal with no X, and then use Ctrl+u, whatever I typed is stored in the bash "clipboard" (for lack of a better term), and I can type it again doing Ctrl+y. How can I copy the results from a grep command on a text file to such bash clipboard? For example, if I have an INSTALL file like this: ./installprocedure --do-some-long-and-complicated-operation-on-dir dir1 How can I copy the content of a grep command so that it's available doing Ctrl+y? For example: copy content to bash clipboard "grep installprocedure INSTALL" Ctrl+y ./installprocedure --do-some-long-and-complicated-operation-on-dir dir1 #cursor available here

• Is Protune for video only or may be used for photo too?

  - by Green

  I have Hero3+ Black Edition. I can't understand if Protune is for video only or may be applied for photos? The manual says it is both for video and for photo (page 35): High-Quality Image Capture Protune’s high data rate captures images with less compression, giving content creators higher quality for professional productions. Film/TV Rate Standard While shooting in Protune, you have the option of recording video in cinema quality 24 fps to easily intercut GoPro content with other source media without the need to perform fps conversion. But at the same time their site says that Protune is for video only: To record Protune footage, you’ll need to turn Protune ON in your camera’s settings menu. What for is Protune? Photo? Video? Or both?

• How to mount a iSCSI/SAN storage drive to a stable device name (one that can't change on re-connect)?

  - by jcalfee314

  We need stable device paths for our Twinstrata SAN drives. Many guides for setting up iSCSI connectors simply say to use a device path like /dev/sda or /dev/sdb. This is far from correct, I doubt that any setup exists that would be happy to have its device name suddenly change (from /dev/sda to /dev/sdb for example). The fix I found was to install multipath and start a multipathd on boot which then provides a stable mapping between the storage's WWID to a device path like this /dev/mapper/firebird_database. This is a method described in the CentOS/RedHat here: http://www.centos.org/docs/5/html/5.1/DM_Multipath/setup_procedure.html. This seems a little complicated though. We noticed that it is common to see UUIDs appear in fstab on new installs. So, the question is, why do we need an external program (multipathd) running to provide a stable device mount? Should there be a way to provide the WWID directly in /etc/fstab?

• Why OpenDialog.py don't work on Jotty application

  - by venerable13

  I'm a Python beginner, I installed quickly, I wrote a "quickly tutorial" in terminal and I did all the steps before at: "However, the application is not complete. There are a few things left for you to do:" All the next steps aren't finished yet because when I use open dialog and select one of the files saved, the content of the file isn't showed on "textview1", Why? Only is deleted the content written. Before if was used without dialog works great. SaveDialog.py work great. -def on_mnu_new_activate(self, widget, data=None) don't work neither. -If I use the bold lines by the others don't work. ###def open_file(self, widget, data=None): def on_mnu_open_activate(self, widget, data=None): ###def save_file(self, widget, data=None): def on_mnu_save_activate(self, widget, data=None): To view the code, go to the link above, unrar the archive, install "quickly" if you don't have it yet, place inside on jotty directory, then put "quickly run", "quickly edit", "quickly design", depending what do you want to do. Code - problematic code with OpenDialog implemented. Code-part1 - works OK, but without OpenDialog. I need principally that OpenDialog function work great.

• What technologies are needed to be a freelance web developer / designer targeting small businesses?

  - by Jason Wirth

  First off, I'm not looking for this answer: "learn PHP/MySQL, JQuery, HTML/CSS...." My background, I wear many hats, and do many things. Currently I manage investment accounts with a business partner who is also a friend. He happens to be attending business / law school perusing a joint JD and MBA. As a result, we're putting our into "coast", maintaining our current clients, but not acquiring more. Recently I've picked up some freelance graphic design / web development / online marketing side work (Photoshop, HTML/CSS, WordPress) through some personal networks. The work is enjoyable; now I'm thinking about expanding it into a larger business with these primary goals: augment my finances (I'm shooting for about $1,000-2,000 per mo.), learn new technologies, involve myself with meaningful work. As an entrepreneur I don't mind the aspects of running a business that hassle other freelancers... -- the marketing -- the billing -- etc. I'm considering targeting the small to middle market businesses and organizations where I can contribute in marketing, design, and development building projects from the ground up. Thus I'll have freedom to decide the specific technology (I won't have to work with an existing code base). What kinds of projects should I focus on? What technologies are a good fit for this style of work? For example: It might be fun to develop with Ruby on Rails. However, maybe a lot of projects would be rolling out e-commerce solutions. Thus, I should focus on PHP due to more shopping cart options, skipping ROR entirely.

• Java EE Basic Training with Yakov Fain

  - by reza_rahman

  Those of us that have been around Java/Java EE for a little while sometimes tend to forget that Java is still an ever expanding ecosystem with many newcomers. Fortunately, not everyone misses this perspective, including well-respected Java veteran Yakov Fain. Yakov recently started a free online video tutorial series focused on Java and Java EE for absolute beginners. The first few parts of the series focused on Java SE but now Yakov is beginning to cover the very basics of Java EE. In a recent video he covered: The basics of the JCP, JSRs and Java EE How to get started with GlassFish 4 The basics of Servlets Developing Java EE/Servlets using Eclipse and GlassFish The excellent video is posted below. The slides for the tutorial series generally are available here. If there are folks you know that would benefit from this content, please do pass on word. Even if you are an experienced developer, it sometimes helps to sit back and review the basics... It's quite remarkable that someone of Yakov's stature took the time out to create content for absolute beginners. For those unaware, Yakov is one of the earliest Java champions and one would be very hard pressed to match his many contributions to the Java community. The tutorial demonstrates his continued passion, commitment and humility.

• How do I troubleshoot a page not found error when configuring IIS6 Windows Server 2003? [Page Not Found]

  - by Vinicius Ottoni

  I have configured IIS6 in my windows server 2003 with this link: http://www.simongibson.com/intranet/iis6/ After that I create a new web site inside Web Sites directory. Inside the physical path I created an index.htm that has: <html> <body>Test</body> </html> But I got the following error: "The page cannot be found". When I put the same index file inside the Web Site Default physical path, it works. I configured the new web site with the link above using the IP configuration and without a Host Header.' What should I do to troubleshoot this or is there an obvious configuration error?

• iPad connection to external monitor

  - by user1234

  Apple have been relatively restrictive in the way in which they have enabled the iPad to be connected to an external display i.e. only certain things like videos and images can be displayed in this way (via a converting lead). Does anyone know of a way to get around this? I.e. display any content on the iPad on an external display - not just the apps/content that Apple has designated? For example, I want to connect my iPad to an external monitor and create documents, viewing them on the monitor not the iPad display? Thanks in advance for any help.

• Is there a formula for this?

  - by Gortron

  TL/DR: Any way to work out if known numbers between a known start and ending figure should be positive or negative numbers? I am developing an application in PHP which can import and read PDFs. The PDFs are financial ones such as bank statements with records of transactions in and out of a bank account. I only have PDFs to work with, no other formats such as CSV unfortunately. I convert the PDF to HTML using pdftohtml and start parsing the data, the intended end result is an array of transactions. So far I have it working smoothly collecting dates, descriptions and balance. Converting the XML instead doesn't help. There are other pieces of transcriptional data such as debit or credit amounts. In the PDF, the credit amount is in one column and the debit amount is in another column so it is quite clear in the PDF. However, when converted to HTML, the formatting is lost and therefor I don't know if the amount was a credit or debit amount. So, my question is, given a starting balance and an ending balance and several known figures in between, is it possible for a programme to work out if those known figures in between are credit or debit amounts? I imagine there could potentially be several combinations of those known values to reach the ending balance so I'd like to apply a formula to return the correct credit/debit sequence only if its the only possible solution. If there are several ways of adding/subtracting the known values to reach the end balance, I can ask the user to look at it manually but I'd like to keep this to a minimum if possible. Possible to do, do you think? Thank you in advance for any help.

• Mail Server on Google Apps, Hotmail Blocks

  - by detay

  My company provides private research tools (sites) for companies. Each site has its own domain name and users. These sites need to be able to send outbound mail for notifications such as password reminders. We started using Google Apps for this purpose, but lately we are having tremendous problems with mailing, especially to hotmail. I added the SPF record as required. Mxtoolbox says my domains are not in any blacklists. I was told to contact https://postmaster.live.com/snds/addnetwork.aspx and add my network. Given that I am using google's mail servers for sending mail, should I add their IP address for registering my domain? Or should I add my server's IP even though I am not hosting the mail server on it? Here's an example of a returned message; > Delivered-To: [email protected] Received: by 10.112.1.195 with SMTP > id 3csp62757lbo; > Mon, 10 Dec 2012 10:42:55 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; > d=gmail.com; s=20120113; > h=mime-version:from:to:x-failed-recipients:subject:message-id:date > :content-type; > bh=x41JiCH75hsonh+5c/kzwIs7R8u4Hum2u396lkV3g2w=; > b=v+bBPvufqfVkNz2UrnhyyoGj1Cuwf6x/yMj0IXJgH27uJU7TqBOvbwnNHf33sQ7B9T > uGzxwryC2fmxBh72cGz1spwWK348nUp6KK73MXKnF8mpc3nPQ8Ke+EQpSPeJdq/7oZvd > scZTGpy//IiGEUDU5bJ7YPqYXQRycY5N6AF5iI4mWWwbS4opybp3IKpDDktu11p/YEEO > Fj9wnSCx3nLMXB/XZgSjjmnaluGhYNdh3JFtz83Vmr50qXTG/TuIXlkirP73GfGvIt2S > 7sy8/YdEbZR92mYe9wucditYr7MOuyjyYrZYCg+weXeTZiJX1PfBVieD+kD9MnCairnP > rQeQ== Received: by 10.14.215.197 with SMTP id e45mr52766237eep.0.1355164974784; > Mon, 10 Dec 2012 10:42:54 -0800 (PST) MIME-Version: 1.0 Return-Path: <> Received: by 10.14.215.197 with SMTP id > e45mr65950764eep.0; Mon, 10 Dec 2012 10:42:54 -0800 (PST) From: Mail > Delivery Subsystem <[email protected]> To: > [email protected] X-Failed-Recipients: ********@hotmail.fr > Subject: Delivery Status Notification (Failure) Message-ID: > <[email protected]> Date: Mon, 10 Dec 2012 > 18:42:54 +0000 Content-Type: text/plain; charset=ISO-8859-1 > > Delivery to the following recipient failed permanently: > > *********@hotmail.fr > > Technical details of permanent failure: Message rejected.

• SharePoint doesn't support this authentication scheme.

  - by EtherDragon

  I have a new Windows Phone 7 phone, and I'm trying to investigate how to connect the Office application to our SharePoint site(s). In the Office application, on Phone 7, I flip to the SharePoint page. I go to open URL, and enter the url for one of my sites, that uses default authentication (Windows Auth). I get a message: Can't open SharePoint doesn't support this authentication scheme. For assistance, contact the person who manages thus SharePoint site (That would be me). You can try opening the content in your web browser instead. When opening in my browser, I can access the content without any problem. (Windows Auth passes) Anyone have any source material on what I should do to my SharePoint site to "support this authentication scheme?" Note: I am the administrator of our SharePoint server farm(s).

• How to generate good serials for DNS zones with Puppet?

  - by Bittrance

  My tradition is to set all zone serials to the timestamp at modification. Now that Puppet is my new religion, I want to set serial timestamps when building zone files from exported resources. A somewhat trivialized example may look like this: file { "/tmp/dafile": content = inline_template("<%= Time.now.to_i %>"), } The problem with this approach is that content will be different all the time, which will (ultimately) provoke rebuilding of zone files on each puppet config poll. Is there some way I can insert a timestamp without it being included in the data that is compared against previous state?

• Start TLS and 389 Directory

  - by Kyle Flavin

  I'm trying to configure Start TLS on 389 Directory server, but I'm having all sorts of issues. I've been following this doc: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/managing-certs.html which specifies that I should create a certificate for both the directory server and admin server. I've imported the CA cert on both servers. I've tried to use the same server certificate for both. It will not allow me to do so. However, the admin and directory servers reside on the same host. If I generate a new certificate it will need to use the same hostname. I'm not sure if that's valid... Has anyone out there set this up before? Any direction would be helpful. I have multmaster replication set up. From an external client, I'm attempting to do an ldapsearch -ZZ -x -h "myhost" -b "dc=example,dc=com" -D "cn=Directory Manager" -W "", and I'm getting a protocol error.

• Apache routing vhosts to /var/www

  - by FHannes

  One user at my site has reported that he reaches the content at /var/www when browsing to any of the vhosts at my server. As far as I’m aware, my Apache server does not contain a document root that references this folder. On top of that, this user seems to be the only one experiencing the issue. According to his ISP, the issue isn’t caused by them, yet, on his mobile connection, he can access the site. When browsing to my server’s IP, he also receives the correct content from the default vhost. What could be the possible causes of this issue and how can I get it to stop? I’ve explored pretty much every option I could think of.

• How to rewrite index.php (and other valid default files) to the document root using mod_rewrite?

  - by TMG

  Hello, I would like to redirect index.php, as well as any other valid default file (e.g. index.html, index.asp, etc.) to the document root (which contains index.php) with something like this: RewriteRule ^index\.(php|htm|html|asp|cfm|shtml|shtm)/?$ / [NC,L] However, this is of course giving me an infinite redirect loop. What's the right way to do this? If possible, I'd like to have this work in both the development and production environment, so I don't want to specify an explicit url like http://www.mysite.com/ as the target. Thanks!

• Help me with this logic (newbie) [migrated]

  - by Surendra

  I need to generate a half pyramid number series with the entered starting number and the number of lines in a html page using Javascript and show the result in html page . I have done the Java scripting and stuff . What I don't get is the logic to it. Take a look at this you may get an idea what I'm talking about: Here is my function in Javascript that will be triggered on a button click function doFunction(){ var enteredNumber=document.getElementById("start"); var lines=document.getElementById("lines"); var result; for(i=0;i<=lines.value;i++) { for(j=enteredNumber.value;j<=i;j++) { document.write(j + "&nbsp;" + "&nbsp;"); } document.write("<br />"); } } Help me with the logic to print following order: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 There is a condition. I will specify $start and $lines. If $start = 5 and $lines = 3 then output should be like: 5 5 6 5 6 7 I have had used the for loop , but that doesn't work if I give my own start number that is higher than the number of lines. I actually need it done with Javascript, I have had done the necessary but I'm confused with the logic to generate such series (with the user given values) I had actually used two for loops to generate the regular number series like below 1 1 2 1 2 3 and so on.

• IE 9:Release

  - by xamlnotes

  Yippie: IE 9s coming out March 14!: http://windowsteamblog.com/ie/b/ie/archive/2011/03/09/a-more-beautiful-web-launches-on-march-14th.aspx For you guys that love other browsers that’s ok. Personally I love IE for many reasons such as ease of use and stability.  I am cranked up to see what IE 9 does as it was retooled from the start. So this one should be big. Also, its bringing HTML 5 support now so we can have much richer applications. Its about time that HTML was revved to move from the old text like stuff to a better model. More info: http://windowsteamblog.com/ie/b/ie/archive/tags/ie9/ Some glimpses here: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features and http://www.beautyoftheweb.com/#/highlights/all-around-fast   Looks like it will be much faster (with hardware support now) in many areas.  Better startup times and install times are hot on my list of favorites too. Plus they retooled the UI in many places too.  The UI looks a lot cleaner now: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features/focused-on-your-websites Plus theres tons more like changes in tab pages, a notfication bar, pinned sites and so forth. Plus theres cool integration with Windows 7 also.

• Apache httpd VirtualHost config - multiple sites

  - by DaFoot

  [Advised to post here from StackExchange] I have a site to work on, because of the way the URLs are built the application seems to have been created on the assumption that it will be at the server root (only app). On my dev server I have other projects and up to now a simple symlink has been working for me, but that's not the case now because this new app wants to sit at the route and process all URLs arriving on :80. Hopefully this snippet from httpd.conf will help explain what I'm trying to acheive: # default for any not matched elsewhere <VirtualHost *:80> ServerName localhost DocumentRoot /var/www/html/newproject </VirtualHost> # now try to pick out specific URLs <VirtualHost localhost/webdev> DocumentRoot /var/www/html/existingProject ServerName localhost/project </VirtualHost> Also need to be able to get same affect from wherever I'm accessing the httpd instance from. Hope that makes sense.

• Thunderbird: filters don't match links

  - by Gregory MOUSSAT

  I use filters to remove some undesirable messages (in addition to the intergrated spam filter). This is great to avoid tons of boring people who want to sell me tons of boring stuff. My problem is, since years (so with every Thunderbird release I ever had, even the current one which is up to date) it is unable to filter links. For example I want to delete every messages containing a link to http://xxxxx.emv3.com/xxxxxx I never managed to remove those emails. I use a filter on the body, checking if it contains emv3 but this never match. Those emails are in HTML format, and the links are displayed as a text like "Visit our website" or so. If I write a HTML email with a link, my filter works. When this is a spam, this never works. When I save the email to a text file, I open it with notepad and I see several http://xxxxx.emv3.com/xxxx Any idea why this don't work ? And how can I do ?

• Is there any diff tool for XML files?

  - by qedi

  Are there any good (Linux) tools for diffing two XML files? Ideally, I would like to be able configure it to some things strict, or loosen some things, like whitespace, or attribute order. I'll often care that the files are functionally the same, but diff by itself, would be annoying to use, especially if the XML file doesn't have a lot of linebreaks. For example, the following should really be okay to me: <tag att1="one" att2="two"> content </tag> <tag att2="two" att1="one"> content </tag>
