  • Blender/POV-Ray differences

    - by Magnap
    I am currently following a tutorial for Blender, but came across POV-Ray mentioned as a renderer. After having researched it a bit, i took a look at it's scene description (scripting) language, which kind of fascinated me. But, after even more googling of the topic, i am still wondering: What are the main and key differences between working with 3D in resp. Blender and POV-Ray? PS: I suspect this might not be the best place for a question such as this, but it seems to be the most suitable.

  • Python: how to calculate data received and send between two ipaddresses and ports [closed]

    - by ramdaz
    I guess it's socket programming. But I have never done socket programming expect for running the tutorial examples while learning Python. I need some more ideas to implement this. What I specifically need is to run a monitoring program of a server which will poll or listen to traffic being exchange from different IPs across different popular ports. For example, how do I get data received and sent through port 80 of 192.168.1.10 and 192.168.1.1 ( which is the gateway). I checked out a number of ready made tools like MRTG, Bwmon, Ntop etc but since we are looking at doing some specific pattern studies, we need to do data capturing within the program. Idea is to monitor some popular ports and do a study of network traffic across some periods and compare them with some other data. We would like to figure a way to do all this with Python....

  • Need advise on linking apache and tomcat

    - by hsnm
    I have been searching this for hours with no luck. I have a web server that uses https on Apache2. I also have installed tomcat7 on the same server to run some Java webapp on it. I need to keep my https port 443 on Apache but forward the requests to the Java webapp to tomcat. I tried to use mod_jk to redirect the requests to tomcat but I failed. Most tutorials talk about redirecting plain http requests not https. I also could not let tomcat use https on 8443. I'm following the steps here but facing errors. The question: Can I redirect https traffic to tomcat without installing https on tomcat? Is there a good tutorial you can recommend to me?

  • Can't change read only folder in windows 7

    - by James Drinkard
    I'm trying to run a Spring MVC 2.5 tutorial and when I run the ant script for a deploy, I get this error: deploy: [copy] Copying 2 files to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp BUILD FAILED C:\projects\workspace\springapp\build.xml:46: Failed to copy C:\projects\workspace\springapp\war\WEB-INF\web.xml to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml due to failed to create the parent directory for C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml After reviewing the directory: springapp I saw the properties as read-only. No problem I thought as I'm logging in as administrator. However, changing the uac settings, going to a command prompt as admin and then trying to change the properties of the folder with attrib, making me the owner of the folder, changing the security settings etc... did nothing. I can't seem to change this folder to anything. So my question is, how do I change the settings on that folder so ANT can make changes to that folder?

  • piecing together a jquery form mailer

    - by Joel
    Hi guys, My newbieness is shining through here...I managed to piece together a form mailer that works great, but now I need to add two more fields, and I'm at a loss as to how to do it. Over the months, I have commented out some things I didn't need, but now I'm stuck. I borrowed from this tutorial to make the original form: http://trevordavis.net/blog/tutorial/ajax-forms-with-jquery/ But then I cannibalized it to make an email signup form for a newsletter, so the fields I need are: recipient email (me-hard coded in) senders email address subject (hardcoded in) first name and city in the body of the message For my form, I have this: <div> <?php include('verify.php'); ?> <form action="index_success.php" method="post" id="sendEmail" class="email"> <h3 class="register2">Newsletter Signup:</h3> <ul class="forms email"> <li class="name"><label for="yourName">Name: </label> <input type="text" name="yourName" class="info" id="yourName" value=" " /><br> </li> <li class="city"><label for="yourCity">City: </label> <input type="text" name="yourCity" class="info" id="yourCity" value=" " /><br> </li> <li class="email"><label for="emailFrom">Email: </label> <input type="text" name="emailFrom" class="info" id="emailFrom" value="<?= $_POST['emailFrom']; ?>" /> <?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>'; ?> </li> <li class="buttons email"> <button type="submit" id="submit">Send</button> <input type="hidden" name="submitted" id="submitted" value="true" /> </li> </ul> </form> </div> emailcontact.js: $(document).ready(function(){ $("#submit").click(function(){ $(".error").hide(); var hasError = false; var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var emailFromVal = $("#emailFrom").val(); if(emailFromVal == '') { $("#emailFrom").after('<span class="error">You forgot to enter the email address to send from.</span>'); hasError = true; } else if(!emailReg.test(emailFromVal)) { $("#emailFrom").after('<span class="error">Enter a valid email address to send from.</span>'); hasError = true; } var subjectVal = $("#subject").val(); if(subjectVal == '') { $("#subject").after('<span class="error">You forgot to enter your name.</span>'); hasError = true; } var messageVal = $("#message").val(); if(messageVal == '') { $("#message").after('<span class="error">You forgot to enter your city.</span>'); hasError = true; } if(hasError == false) { $(this).hide(); $("#sendEmail li.buttons").append('<img src="/wp-content/themes/default/images/template/loading.gif" alt="Loading" id="loading" />'); $.post("/includes/sendemail.php", //emailTo: emailToVal, { emailFrom: emailFromVal, subject: subjectVal, message: messageVal }, function(data){ $("#sendEmail").slideUp("normal", function() { $("#sendEmail").before('<h3 class="register2">Success!</h3><p class="emailbox">You are on the Newsletter email list.</p>'); }); } ); } return false; }); }); sendmail.php: <?php $mailTo = $_POST['emailTo']; $mailFrom = $_POST['emailFrom']; $subject = $_POST['yourName']; $message = $_POST['yourCity']; mail('[email protected]','Rattletree Newsletter', 'Name='.$subject.

  • snort-mysql not starting on Ubuntu server

    - by Rsaesha
    I am following this tutorial: https://help.ubuntu.com/community/SnortIDS I've set up the database, everything has installed correctly, and I've configured the snort.conf file so it outputs to a database (with creds all filled out ok). When I run /etc/init.d/snort start, it fails but does not produce any error message other than [fail]. The last few lines of /var/log/syslog are: snort[5687]: database: must enter database name in configuration file#012 snort[5687]: FATAL ERROR: My output database line in the snort.conf file is: output database: log, mysql, user=snort password=... dbname=snort host=localhost I have tried it with the commas separating everything, putting quotes around stuff, etc. The password is only made up of letters (after I thought maybe a number was throwing it off).

  • How To Adjust Properly Brightness And Contrast On Monitor

    - by Johannes
    This days, it seems that I either go worse with my eyes or some settings with contrast and brightness have been changed. However, I have been searching now for some tutorial on how to adjust contrast and brightness, and I have found already some, on how to use Microsoft Win7 Calibrate Display Color program, but some people don't recommend it.. My monitor control menu shows settings (which are by default) that contrast is set to 80, contrast to 90 and sharpnes to 45, for which I belive are pretty dam high. I'm usually every day in front of my PC about 6-10h. The biggest problem is, when the night comes, and I have to read some word document, after a 10-15m of reading, eyes starts hurting. I'm using ASUS VW198 and Nvidia 9800 GT graphic card. So please suggest me, what should I decrease, contrast or brightness or both?

  • How to set up a subdomain in nsd3

    - by qliq
    nsd3 is very little-known but super-lightweight and stable DNS server which makes it a great alternative to bind9 be used on low-end boxes. There is a very good tutorial here that describe how to set it up. My problem is that I need to set up a subdomain subd1.example.com that will be severed on another VPS. I tried to add subdmn1.mymaindomain.com. IN 1.2.3.5 (Assuming that my destination IP is 1.2.3.5) Then I nsdc rebuild service nsd3 restart However the subdmn1.mymaindomain.com fails to resolve to the IP. Any clues will be much appreciated.

  • Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

    - by iyl
    I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

  • Set Up Remote Desktop at Home

    - by Rev
    I'm sure this has been asked before, but I'm unable to find a clear set of instructions. I'm currently using LogMeIn Hamachi to enable Windows 8's Remote Desktop feature on my home computer (running Win8 Pro x64). Unfortunatley, I can't use this method to access my home computer from my Surface Tablet, as I can't install in the Hamachi client. So how can I set up Remote Desktop without using LogMeIn Hamachi? A link to a noob-friendly tutorial would be greatly appreciated. I haven't been able to find anything that I understand (and I am pretty technical, router stuff just stumps me for some reason). EDIT: And I don't want to use a third party service like TeamViewer, in my experience those tools are laggy and quite horrible. The Remote Desktop feature has been excellent.

  • How can I use sudo when I logged in with a SSH key in PuTTY?

    - by Alex
    I know the title probably doesn't even make sense, but anyway. I downloaded PuTTY and set it up, and followed this tutorial to set up SSH keys so I don't have to input a user or password when logging in with SSH. I noticed that when I made a new user I used the --disabled-password parameter, since I wouldn't be needing it... but now when I give the user sudo powers I can't proceed as it asks me for the user's password, and I don't have one. What do I do?

  • Bonding and default gateway problem (CentOS)

    I configured network bonding on two machine with centos 5.5. Bonding works well, but the problem is default gateway: it is not configured! I follow this tutorial. I added GATEWAY in both (and either) /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-bond0. But, when I restart network (or server) there is no default gateway (route command). This is ip route ls output after network restart: 10.0.0.0/16 dev bond0 proto kernel scope link src 10.0.0.88 Where is my mistake?

  • Learning Puppet Exercise - Installing httpd package and starting service

    - by Quetzalcoatl
    I'm working my way through the Learning Puppet guide on manifests, and I am stuck on the exercise at the bottom of the page which asks you to install the httpd package and start the httpd service. So far my manifest looks like: package { 'httpd': ensure => present, } service { 'httpd': ensure => running, enable => true, } However, upon trying puppet apply on it, I get: From looking at other examples of similar manifests, I cant quite figure out what the issue is - I presume the attempt at installing the package httpd failed? Unfortunately the error message isn't particularly helpful here. Any assistance anyone can provide would be greatly appreciated. I'm running their VMWare Learning Puppet VM (PE 2.7.0) that was provided for this tutorial.

  • Is there any trick to join and use Windows 8/8.1 with Samba 4 (4.1.6)?

    - by tenshimsm
    It seems that Samba doesn't like at all. I've followed various tutorials and I can't get Windows 8 to work properly with a Ubuntu Server as domain controller. This week i've downloaded ubuntu 14.04 lts and set a fast domain configuration. As usual all other Windows version (XP and 7) work but the newest M$ nightmare doesn't. In this try it doesn't even join the domain, keeps saying the my username or password are wrong. My /etc/samba/smb.conf # Global parameters [global] workgroup = DOMAIN realm = DOMAIN.LAN netbios name = DOM server role = active directory domain controller dns forwarder = 8.8.8.8 idmap_ldb:use rfc2307 = yes [netlogon] path = /var/lib/samba/sysvol/domain.lan/scripts read only = No [sysvol] path = /var/lib/samba/sysvol read only = No [test] directory mode = 0750 path = /SHARES/test read only = no Does anyone have a tutorial that really works? Because I've tried many, each one with different configurations that works only with the people that made them. And is there a way to import my old AD users, computers and ID in a way that I won't need to rejoin all computers?

  • Open mail-links with gmail in Chrome 9

    - by moose
    it happens quite often, that I click a link over a persons name, just to see that it launches the default mail client of my system. I thought it would be a normal link, but it was a "mailto:"-link. I would like Chrome to start gmail, not my default email client. For Firefox, I had only to paste this in the URL-Bar: javascript:window.navigator.registerProtocolHandler("mailto","https://mail.google.com/mail/?extsrc=mailto&url=%s","GMail") Unfortunately, it doesn't work in Chrome 9. I have found this tutorial for Ubuntu, but I would like a solution in Chome. If it is only in Chrome, I can sync the settings. (So How do I make mailto: links open gmail in Ubuntu? doesn't fit) http://www.google.com/support/forum/p/Chrome/thread?tid=2aad08042607a4eb&hl=en could be related to my problem, but there is no answer.
