  • Setting up DNS in WHM/cPanel

    - by Jon Furmanski
    I don't understand what I'm doing wrong, but I'm sure this is a simple fix. I setup WHM/cPanel for the first time on my VPS and understand how DNS works for the most part (or so I thought). I created under the main domain name 2 nameservers (ns1.maindomain.com & ns2.maindomain.com). I have 2 IP address for my sever so each one points to a unique IP: ns1.maindomain.com => 198.x.x.204 ns2.maindomain.com => 198.x.x.205 I also set up reverse DNS with my hosting provider. When I put in my two nameservers under another domain (secondary domain), GoDaddy states that the nameservers are invalid. Any ideas on why this is or any configurations in cPanel that need to be made?

  • .htaccess: Transparently adding a name to the request

    - by Jon
    I've read this tutorial about how to modify your .htaccess in order to server many web2py applications but it doesn't seem to work. Here is my .htaccess RewriteEngine On RewriteRule ^dispatch\.fcgi/ - [L] RewriteRule ^(.*)$ dispatch.fcgi/$1 [L] RewriteCond %{HTTP_HOST} =www.moublemouble.com [NC, OR] RewriteCond %{HTTP_HOST} =moublemouble.com [NC] RewriteRule ^/(.*) /moublemouble/$1 [PT,L] All I get is a 500 Internal Error and .htaccess is not my strong point. Any clues?

  • Silverlight: Creating great UIs

    - by xamlnotes
    I was always told I was left brained and could not draw. And I bought into that view. Somewhere down the road years ago I did learn to play guitar and to play by ear at that.  Now that’s not all left brained so my right brain must be working.  About a year ago, my good friend Billy Hollis turned me own to a book by Betty Edwards (http://www.drawright.com/).  I started reading this and soon I found my self drawing on napkins in restaurants while we were waiting on food and at many other times too.  Dang’d if I could not draw! Check out my UI article at Dev Pro Connections (Great UIs article) on some of my experiences. Heres a few more links that are really cool too. Cool color combinations web site Simply painting is awesome. Saw this guy on tv. This site has some great tools for color contrasting

  • How to set Visio 2003 Trusted Locations

    - by Jon Fournier
    I see the option in Visio 2003 to only trust macros stored in trusted locations, but I can't find any way to set up what these trusted locations are. My problem is I have a template file that's not signed in the VBA project but the VBA project is locked (so I can't just sign it myself). So, there are only two ways I can stop the warning: lower my security settings so anything with macros will run (not a good idea) Tell Visio that the template is in a trusted location (if this is even possible)

  • Get sudoers information for all users on a server

    - by Jon Kruger
    I want to collect information on what sudoers actions a user can perform on a server. From what I've read, you can do this with the command sudo -l -U username. However, one server that I have has a slightly older version of sudo (1.6.7p5) and the -U option doesn't seem to exist (I don't own the server so I can't just upgrade to a newer version of sudo). Has anyone ever had to collect sudoers information for all users on a server? How would you recommend doing it?

  • UI Design Patterns : Are you developing a Fusion Apps extension, an ADF or Webcenter App?

    - by asantaga
    A big question I get asked when speaking to partners who are developing Oracle ADF, or Webcenter, Apps is how to make it look nice.. Some of the big SIs ask me, "Do we have any design patterns/guidelines we can use?". .. Alas website design is a very personal thing and each website will have different requirements and needs, however I am now pleased to say we've just launched "Oracle Fusion Applications Design Patterns" website.   The website is the result of many years of Oracle R&D into user interface design for Fusion applications and features a really cool web app which allows you to visualise the UI components in action. Although many of the design patterns are related to ADF , its worth noting that ADF took its lead from Oracle Fusion Applications User Interface needs - not the other way around, its just taken us a while to publish these. Coupled together with the dashboard patterns this makes are really cool extra asset for your kit bag Design Patterns Oracle dashboard patterns and guidelines Usable Apps.oracle.com Enjoy

  • How can I port forward with an airport extreme and a NAT enabled modem?

    - by Jon
    I run an Actiontec HD701D modem with NAT to an Airport extreme base station to laptop etc. As you might expect I get double NAT issues. I tried a lot of different things to forward a port, but no luck. Currently the airport is in bridge mode letting the modem handle the NAT, but still can't forward the port. Also to note: firewall is off on the router, firewall is set to allow the application in OSX 10.6.3 and I did forward the port in the router. No luck.

  • One-Way Backup Service? [closed]

    - by Jon Rodriguez
    Up until a month ago, my girlfriend has used MobileMe to backup all the files on her MacBook. This turned out terribly when a quirk of MobileMe caused it to erase all of her files on MobileMe, and then sync the newly-erased MobileMe down to her computer, erasing everything. A week's worth of college essays and CS homework were gone. Now, I am terrified of any commercial cloud-backup solutions because of the possibility of this happening. Going off the list provided in these answers, could you please help me find a good backup service that is completely one-way? I want a service where there is literally not a single line of code that has the possibility of writing to my computer's drive. I want a pure one-way backup service.

  • hosts file for ip address

    - by Jon Clegg
    I would like to map ip address to specific localhost interfaces (e.g. 23.45.66.77 = 127.0.3.3). For named hosts I can use the hosts file. Naturally this doesn't work for IP address. This has to work in windows, the only option I've found so far is implementing a TAP/TUN driver like openvpn does. Are there any other options?

  • Why does my exchange message filtering rule not work?

    - by Jon Cage
    I have two rules set up to sort incoming bug reports. The first is specific to a single device: Apply this rule after the message arrives sent to SMS Distribution and with <source_device_number>: in the body move it to the BugReports\<source_device_number> folder ..and the second is a catch-all for everything else: Apply this rule after the message arrives sent to SMS Distribution move it to the BugReports folder For some reason though, the first rule never seems to act even though it's higher in the list. So for some reason an email like the following doesn't seem to get caught by the first rule: From: <SourceDeviceUID> To: SMS Distributor Subject: Message from <SourceDeviceUID> Message: <source_device_number>: Device encountered a problem. Details below... ...where <source_device_number> is an integer. The second rule works fine. But for some high-priority devices, I want them automatically sorted. Why might that first rule fail?

  • Seasgate GoFlex NAS + Horrible Speed = Bad Experience

    - by Jon H
    I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

  • Postfix - How to configure to send these emails?

    - by Jon
    I want my mailserver to send mail from my local application "from" any user supplied email address "to" my own address, say "[email protected]". The MX records for "mysite.com" actually point to a different server, even though the outgoing mainserver is running with mydomain set as "mysite.com". Perhaps this is part of the problem? postfix is currently causing a SMTPRecipientsRefused error within the python application. Can anyone point me to what to change in the configuration?

  • Why do server administrators not open up IMAP on an Exchange server?

    - by Jon
    In a corporate environment running Exchange and Outlook clients connecting to it why do server administrators not allow IMAP to be turned on for those that would like to connect to the server using IMAP? I'm assuming the simple answer is port attacks and please excuse my naivety but does Exchange not suffer the same problems or is it because its behind the firewall and within the corporate network?

  • How to tell which physical disks have bootable MBR?

    - by Jon
    The computer I am using right now has 6 physical disks attached. Using the BIOS's "select boot device" functionality I have discovered that I can boot off 3 of these disks into the exact same bootloader. This means that all of these disks have the bootable flag set on their MBR, even though I had been under the impression that only 2 of them are in fact bootable. My question is: is there an easy way to check which disks have a bootable MBR with a command line tool or some OS utility? I am aware of the DISKPART tool and its basic functionality, but I haven't found how to view the information I need. The OS is Windows 7 x64 Ultimate with SP1.

  • Updated my WAMP Server and MySQL is eating up 580mB of memory

    - by Jon
    I updated my dev-box's WAMPSERVER, and along with updating PHP and Apache, MySQL updated to '5.6.12'. After doing that, I copied the data folder from my old (5.1.36) install to the new one and now MySQL takes up 580mB which is way too much, since I'm the only person using it (Locally) and there are only 20 or so databases on it, none of which have 'memory' tables. How can I get this down to a decent amount?

  • Connecting a USB laptop to a RJ45 serial port

    - by Jon
    We are about to get our first managed switch at work (Procurve 2520G-24-PoE), and this lowly programmer gets to put on his admin hat and try to configure it. The switch has an RJ45 serial port for console access. My laptop has USB ports but no serial port. In fact, there isn't a single computer in the office with a serial port. I've seen USB-to-DB9 adapters, but I need to go from USB to RJ45 (serial). How would I go about accomplishing this? Do I need two adapters? Will USB-to-DB9 and then DB9-to-RJ45 work? Thanks in advance.

  • On Mac OS X how can I monitor what is using my internet connection?

    - by Jon Hopkins
    I've got a relatively limited broadband connection (I live miles from the nearest exchange) and from time to time net access (but nothing else) slows to a near crawl. I know from a bit of monitoring software that the connection is being fairly heavily used which would explain it but I don't know what's using it. There are certainly plenty of things which might (these days there are dozens of apps that will either regularly or infrequently check data or download updates) but how can I find out? I'm happy to pay (a small amount of) money if needed, though in that case I'd rather it were a recommendation that me just Googling for something.

  • Monitoring tools that can take high rate and high volume?

    - by Jon Watte
    We're using Cacti with RRDTool to monitor and graph about 100,000 counters spread across about 1,000 Linux-based nodes. However, our current setup generally only gives us 5-minute graphs (with some data being minute-based); we often make changes where seeing feedback in "near real time" would be of value. I'd like approximately a week of 5- or 10-second data, a year of 1-minute data, and 5 years of 10-minute data. I have SSD disks and a dual-hexa-core server to spare. I tried setting up a Graphite/carbon/whisper server, and had about 15 nodes pipe to it, but it only has "average" for the retention function when promoting to older buckets. This is almost useless -- I'd like min, max, average, standard deviation, and perhaps "total sum" and "number of samples" or perhaps "95th percentile" available. The developer claims there's a new back-end "in beta" that allows you to write your own function, but this appears to still only do 1:1 retention (when saving older data, you really want the statistics calculated into many streams from a single input. Also, "in beta" seems a little risky for this installation. If I'm wrong about this assumption, I'd be happy to be shown my error! I've heard Zabbix recommended, but it puts data into MySQL or some other SQL database. 100,000 counters on a 5 second interval means 20,000 tps, and while I have an SSD, I don't have an 8-way RAID-6 with battery backup cache, which I think I'd need for that to work out :-) Again, if that's actually something that's not a problem, I'd be happy to be shown the error of my ways. Also, can Zabbix do the single data stream - promote with statistics thing? Finally, Munin claims to have a new 2.0 coming out "in beta" right now, and it boasts custom retention plans. However, again, it's that "in beta" part -- has anyone used that for real, and at scale? How did it perform, if so? I'm almost thinking about using a graphing front-end (such as Graphite) and rolling my own retention backend with a simple layer on top of mmap() and some stats. That wouldn't be particularly hard, and would probably perform very well, letting the kernel figure out the balance between frequency of flushing to disk and process operations. Any other suggestions I should look into? Note: it has to have shown itself able to sustain the kinds of data loads I'm suggesting above; if you can point at the specific implementation you're referencing, so much the better!

  • Easiest way to move my Windows installation to an SSD?

    - by Jon Artus
    I've taken the plunge and bought an SSD and want to move my existing Windows installation over. The current hard disk is 500Gb, but I've trimmed the contents down to about ~40Gb. I'm transferring it across to a 100Gb SSD and looking for the easiest way just to copy everything across and set the SSD up as a boot device. I've looked at a few tools like Macrium Reflect, but they don't seem able to restore to a smaller drive. Do I need to go for something like PING to do this? I'm trying to avoid scary Linux-based boot utilities if possible, does anyone know of an easier way?

  • What shall I include in a 10 week web technologies course?

    - by Iain
    In September I will be teaching a university module on web technologies. This session will be available to 1st year (freshman) students who don't necessarily have any programming knowledge or know how the web works. In the 2nd semester I will be teaching Flash, which is my specialism, so I know exactly what I am going to teach, but in the 1st semester I will be teaching them web standards technologies - HTML, CSS, JS, jQuery, PHP and MySQL. Where I need advice is how to proportion the emphasis for each part, and which parts of each technology to cover. Another real issue I'm struggling with is how much of the bad old ways should I teach them? Do they need to know about bold as well as strong, etc. UPDATE: based, on your feedback I will only be teaching the latest version of everything - CSS3, HTML5 etc. I'm not sure exactly how long the semester will be but I'm guessing about 10-12 weeks. Each session is a 2 hour lab. Obviously there's only so much I can cover in that time and it will be up to the students to go a research this stuff properly on W3 schools etc. My ideas so far were: Lesson 0 - Course intro and overview of the current tech landscape. What is out there, what will we be learning, what won't we. What is a web server, URL etc. Looking at different example websites and discussing how they work. Lesson 1 - HTML basics (head, body, title, img, table, a, lists, h1, strong etc) Lesson 2 - CSS for styling and layout - fonts, webfonts, float etc Lesson 3 - Intro to programming JS (variables, loops, conditionals, functions) Lesson 4 - more JS programming fundamentals, DOM manipulation Lesson 5 - jQuery - making things fly about and look cool Lesson 6 - XML and Ajax Lesson 7 - PHP basics - syntax, server-side principles Lesson 8 - PHP and MySQL - forms, logins, saving user info Lesson 9 - don't know Lesson 10 - don't know Please let me know if you think this is the right order, what have I missed, how to use any spare sessions etc. Thanks :) UPDATE BASED ON RESPONSES: Thanks for all your responses - some great stuff. To be absolutely clear, this is not a computer science course, it is a practical module on a creative technology course. The emphasis definitely has to be on making cool things work rather than understanding how the backbone of the internet works. That can come later, if the students are interested. At the end of the module I would like the students to be able to produce a web page or pages that does something cool, using some or all of the technologies I cover. Many of these topics are of course far beyond the scope of a 2 hour session, however I do not have the option of reducing the syllabus, I will just have to explain what the technology does and encourage the student to research it in their own time.
