• Question regarding an NAS server and remote users

  - by JB

  I have a client that requires a massive amount of storage space but: Doesn't want to spend very much money Needs remote users (across the country) to be able to pull data from it and store to it, as well. Can this be done with an NAS Server such as the Western Digital Sharespace Network Storage System? I do not believe the client wants to spend over $1400 and HP is offering 8TB for $1299. Also, if anyone has any other ideas besides using NAS, please let me know. Thanks in advance for any help.

• Exim4 delivery to parent domain.

  - by bruor

  I've set up an ubuntu server 9.1 system with exim4 as a relay for e-mail on my network. I've told exim that it is part of a subdomain: sub.domain.com I can test and deliver messages fine to my gmail accounts. I cannot get exim4 to sent messages to [email protected] though. The error received in the logs shows that exim thinks it should be delivering messages for domain.com to localhost instead of the actual MX for domain.com Is there an easy way to modify the debconf update-exim4.conf.conf so that is has the relay_to_domains capability?

• One domain hiding two servers

  - by George DSeas

  For our SaaS web-app we have two identical servers in two geographically separated data centers. FOO_1 is the production server and does real-time (MySQL master-slave) replication to its backup F00_2. We want our users to always go to THEFOO.COM which somehow points to the production server. So even if FOO_1 dies, we can just switch THEFOO.COM to redirect to FOO_2 so the failure is transparent. This switch can be manual or automatic but without failback (if FOO_1 somehow becomes available again). Is there a way to do this with DNS? I am getting stuck with ANAME and CNAMEs configuration. We don't use sub-domains, just straight domains. If not, what are other options? Does it make sense to just have a web server at LOVELY_FOO.COM and just redirect all traffic? I also looked at load balancers but didn't see a solution for across data centers/network providers.

• Code refactoring with Visual Studio 2010-Part 3

  - by Jalpesh P. Vadgama

  I have been writing few post about Code refactoring features of visual studio 2010 and This blog post is also one of them. In this post I am going to show you reorder parameters features in visual studio 2010. As a developer you might need to reorder parameter of a method or procedure in code for better readability of the the code and if you do this task manually then it is tedious job to do. But Visual Studio Reorder Parameter code refactoring feature can do this stuff within a minute. So let’s see how its works. For this I have created a simple console application which I have used earlier posts . Following is a code for that. using System; namespace CodeRefractoring { class Program { static void Main(string[] args) { string firstName = "Jalpesh"; string lastName = "Vadgama"; PrintMyName(firstName, lastName); } private static void PrintMyName(string firstName, string lastName) { Console.WriteLine(string.Format("FirstName:{0}", firstName)); Console.WriteLine(string.Format("LastName:{0}", lastName)); Console.ReadLine(); } } } Above code is very simple. It just print a firstname and lastname via PrintMyName method. Now I want to reorder the firstname and lastname parameter of PrintMyName. So for that first I have to select method and then click Refactor Menu-> Reorder parameters like following. Once you click a dialog box appears like following where it will give options to move parameter with arrow navigation like following. Now I am moving lastname parameter as first parameter like following. Once you click OK it will show a preview option where I can see the effects of changes like following. Once I clicked Apply my code will be changed like following. using System; namespace CodeRefractoring { class Program { static void Main(string[] args) { string firstName = "Jalpesh"; string lastName = "Vadgama"; PrintMyName(lastName, firstName); } private static void PrintMyName(string lastName, string firstName) { Console.WriteLine(string.Format("FirstName:{0}", firstName)); Console.WriteLine(string.Format("LastName:{0}", lastName)); Console.ReadLine(); } } } As you can see its very easy to use this feature. Hoped you liked it.. Stay tuned for more.. Till that happy programming.

• Announcing Berkeley DB Java Edition Major Release

  - by Eric Jensen

  Berkeley DB Java Edition 5.0 was just released. There are a number of new features, enhancements, and options in there that our users have been asking for. Chief among them is a new class called DiskOrderedCursor, which greatly increases performance of systems using spinning platter magnetic hard drives. A number of users expressed interest in this feature, including Alex Feinberg of LinkedIn. Berkeley DB Java Edition is part of Project Voldemort, a distributed key/value database used by LinkedIn. There have been many other improvements and optimizations. Concurrency is significantly improved, as is the performance of update and delete operations. New and interesting methods include Environment.preload, which allows multiple databases to be preloaded simultaneously. New Cursor methods enable for more effective searching through the database. We continue to enhance Berkeley DB Java Edition’s High Availability as well. One new feature is the ability to open a replicated node read-only when the master is unavailable. This can allow critical systems to continue offering some functionality, even during a network or master node failure. There’s a lot more in release 5.0. I encourage you to take a look at the extensive changelog yourself. As always, you can download the new release and try it out here: http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html

• Frank Ludolph's Last Day at Work

  - by mprove

  Hi Frank, today is your last day at Oracle. I cannot belief that retirement is an alternative to designing software and improving products for decades. I might figure it out myself in a couple of years. Our ways have crossed several times. And I am extremely thankful for that. I still remember my first session on an Apple Lisa. It must have been around 1985. I was still in school, and we were visiting the University of Hamburg to get some orientation on the departments. When I started I chose Informatics. And I suppose the Apple Lisa played a significant role in my decision. Is it fate that I later wrote about Apple Lisa? I’ve attended your presentation and public demo of the Lisa System at CHI ’98 in Los Angeles. Maybe a video still exists. I should look it up and publish it somewhere. You had also booth duty for Sun Microsystems – presenting HotJava Views, a user interface for a network computer. And you were handing out VHS tapes (!) of Starfire. I still have mine – but no player anymore. Then I joined Sun in 2002, and I guess I popped up in your office each time when I came to Santa Clara. The SEED mentoring program finally made it possible that we exchanged and discussed many ideas on the past and future of HCI. Dueling Interaction Models of Personal-Computing and Web-Computing at MEDICI 2007 is one of the results. But do you remember for instance also our jam session with Phil Clevenger on Hello World? Marvelous! I will miss you at Oracle. Enjoy your life and let’s stay in touch.Matthias

• What's the likely culprit in email delay?

  - by Kiki

  If anyone can shed light or point me to a tutorial, I'd appreciate it. We are a tiny company and have experienced occasional delays in receiving email sent between staff members. We are in separate cities but all in the same state; our webhost/email ISP is across the country from us. If it matters, we're on Macs and most of use Entourage. Our email configurations are POP server: companyname.com and SMTP: smtp.companyname.com (When we used our DSL providers for SMTP we had unreliable service) Our ISP says they're not seeing delays related to their equipment and the problem is elsewhere in the network. A co-worker believes that the delays are with the ISP. Is there a good way to figure this out?

• Remote Desktop to Virtual Machine

  - by Valvaris

  Hello: I recently reformatted one of my servers with Windows Server 2008 x64 and with that, installed the latest version of VMWare server on it. Within that, I created a new Windows Server 2003 R2 x86 virtual machine for the purposes of being a backup domain controller. I was able to successfully configure it as a domain controller and have it provide DNS service to my domain. I've been using the VMWare remote console to set this up and figured it was time to get remote desktop working. I set it up as I have with many other computers on my network (hitting the checkbox, making the firewall isn't blocking it) and I cannot get remote desktop to connect to it. I've tried using the computer name and its IP address neither work. I can ping the computer from the outside but the Virtual machine cannot ping anything from inside it. All machines are on the same subnet. I can't seem to figure this out.

• Ask the Readers: How Fast is Your Internet Connection?

  - by Mysticgeek

  The federal government recently announced a broadband initiative that calls for 260 million homes to have 100Mbps Internet connections by the year 2020. This got us wondering, how fast is your current Internet connection? Photo by roland When it comes to the speed of our Internet connection, we all want the maximum possible. The FCC recently announced their National Broadband Plan, which is an initiative to improve the Internet infrastructure in the United States and provide higher speeds to everyone. You’ve also undoubtedly heard the news about Google getting into the mix with their program to bring ultra high-speed fiber broadband to 50,000 users in select cities. While we wait for those programs to come into fruition, we thought it would be cool to check out what kinds of speeds you’re getting now. Test Your Internet Connection Speed There are several sites out there you can use to test your Internet speeds, but probably the best site is Speedtest.net. It’s easy to use, and allows you test download and upload speeds to and from various locations in the US and throughout the world. If you already know the speeds you’re getting leave a comment and let us know. If you use Speedtest.com, just keep in mind that our comment system won’t allow you to copy their result links, but you can simply tell us what you get in the results. We’re especially interested in the results of those of you who have Verizon FIOS or Comcast’s “Ultra” service. Leave a comment and join in the discussion!

• what is a normal developer to pageview ratio?

  - by Anthony Shull

  I work for an e-commerce site that has lately been shedding its workforce. I was hired ten months ago as a UI Developer. At that time we had three other developers. One was the technical lead who had been with the company for 10 years. The other two were server-side developers who had been there for 10 and 3.5 years respectively. In ten months, the technical lead left for a better position, one developer was laid off, and the other very recently left. So, I am now the only developer on staff. We have one DBA and one network administrator. They are currently looking to hire another developer but are not willing to pay enough to hire a senior person. I consider myself a junior developer with two years of experience. I have argued that we need to hire at least one senior developer and another junior developer if we're going to keep our current site operational (not to mention develop new features)...even if that means laying off staff in other departments. Right now we get 6.5 million pageviews per month, and I feel like 3.2 million pageviews per developer must be incredibly abnormal. My question is then: what is a normal developer to pageview ratio? Are there any industry standards or literature on the subject that I can use to argue for more staff?

• What could prevent one Amazon EC2 instance from pinging another instance's Private IP?

  - by ks78

  I have multiple Amazon EC2 instances which need to communicate using private IPs. However, so far I've been unable to ping one instance's private IP from another instance. I can ping external addresses, such as their Elastic IPs and other sites (yahoo, google, etc), so it seems there's nothing wrong with the instances' network configuration. Also, they are all in the same zone, so that shouldn't be an issue. Does anyone have any idea what I could be doing wrong? Could this related to the Security Group settings?

• Ubuntu: The Movie

  - by CYREX

  Since Ubuntu is the most popular distribution and has made a lot of changes in many places around the globe and in different industries up to the point where even people that do not know what Linux is, they know what Ubuntu is (go figure? ) there might be a movie coming someday (like the social network for Facebook or Revolution OS for Linux/Red Hat) i wanted to know how it all came to be from the actual players in the show. UBUNTU: The Movie Since i have seen several of the primary characters of the movie here, this might be a good place to start on how it all came to be. Not in the traditional wikipedia way or the ubuntu help section, but in the what the actual developers have in mind on how it all went down to the point of having a huge amount of users, an incredible level sophistication in the forum, help sections, installers, etc.. This is just to have the KNOW HOW before the actual movie makes it out some day in the future. As a fan of Ubuntu this is a MOST KNOW! ;) Hope i made some people happy and some other shy hehe.

• Displaying ads over WiFi hotspot

  - by Ahsan

  I have recently distributed my WiFi network with highpseed antennas to my area which covers almost 300-400 peoples. I am not charging them anything but i would like to generate some revenue through Advertisements placed on the websites that they visit. Is it possible to display ads from Google (I know i can do redirect the Advertisements, using some cache server or firewall) . Its just like a free vpn but i would like to have my advertisements above the websites they visit so i can take out the cost for the WiFi that i offer. Any suggestions would be great!

• esxi VM will not connect to virual switch

  - by NitroxDM

  I have a exsi box with a VM (Windows 2003) that will not connect to any of the switches. The switch shows the VM connected but I can not ping anything on the network. I have double checked the VM's IP. No dice. There are a ton of messages in the log: [DATE 'VmMisc' NNNNN warning] Failed to validate VM IP address: unknown Update: There are 3 other VMs. Each vSwitch has 56 ports. I can ping from one nic to the other. Each vSwitch shows that the new VM is connect. VMware ESX Server 3i V 3.5.9 Build 123629 Update 2: Out of the blue it just started working. I didn't change anything. I think it has something to do with RRAS.

• How to Grant IIS 7.5 access to a certificate in certificate store?

  - by thames

  In Windows 2003 it was simple to do and one could use the winhttpcertcfg.exe (download) to give "NETWORK SERVICE" account access to a certificate. I'm now using Windows Server 2008 R2 with IIS 7.5 and I am unable to find where and how to set permissions access permissions to a certificate in the certificate store. This Post showed how to do it in Vista and that winhttpcertcfg features were added into the certificates mmc however it doesn't seem to work with imported certificates or doesn't work anymore on Server 2008 R2. So does anyone have any idea on how give IIS 7.5 the correct permissions to read a certificate from the certificate store? And also what account from IIS 7.5 that needs the permission.

• maemo - n900 - SIP call quality

  - by Walter White

  Hi all, I have been using SIP / VoIP on my n900 to make calls and my problem is after about 15 minutes of talk time, more recently 18 minutes exactly, my connection dies and I can no longer hear them or them me. I have tested this with various VoIP providers to confirm that it is not specific to any one provider, but instead my phone. I also have tested this on my laptop. I sent my phone to be tested at some place that tests hardware and no problems were found with the hardware. What can I do to rectify the 15 minute call barrier with SIP on my phone? The other problem I have too is that for the wireless broadband to start working again, I need to restart the phone, it appears the network driver gets overloaded. The one thing that appears to work fine is making cellular calls. I have yet to have call quality drop off after 15 minutes over a cellular connection. Thanks, Walter

• Wake On Lan (WOL) for Realtek RTL8101E/RTL8102E

  - by Heisennberg

  I'm unsuccessfully trying to get Wake on Lan to work with my local server (IP Address : 192.168.0.2, distro Ubuntu 12.04.3 LTS) which has a Realtek RTL8101E/RTL8102E ethernet card.

• Forcing logon to Air Watch server upon joining wifi

  - by DKNUCKLES

  I'm setting up a wireless controller that I would like to leave as unsecured. When a user connects to this network they need to be forwarded to a specific page where they can authenticate with the Air Watch system they have in place. Once authentication takes place, a profile will be downloaded to their device and we can administer the devices accordingly. I'm mulling over how I can force the page to the user when they log in. The methodology I'm thinking about working with is creating a NAT rule for that VSC that would forward all port 80 and 443 traffic to the airwatch server. Once they authenticate, a profile will be downloaded which will connect the devices to an Virtual Access Point who's SSID isn't broadcasted. Is this methodology correct or can someone think of an easier / more efficient way of accomplishing this? The controller is an HP MSM720 for what it's worth.

• What You Said: Your Favorite Co-Op Games

  - by Jason Fitzpatrick

  While competitive gaming is fun, reader response to this week’s Ask the Readers question shows that good old beat-the-bad-guys-together cooperative gaming is as popular as ever. Read on to see what your fellow readers are playing. By far the most popular nomination for favorite co-op game was an outright classic: 1987′s smash hit Contra. Originally released as an arcade game, it was ported to the Nintendo Entertainment System in 1988. Contra was groundbreaking for the time as it featured simultaneous play for the two players–you and a friend could play side by side without waiting to take your turn. Clearly that kind of side-by-side play resonated with readers. RJ writes: When my fiance and I played and beat Contra on the NES. I knew she was the one and we got married and its been great. That’s no small feat; Contra was voted “Toughest Game to Beat” by IGN.com readers. Even readers who had moved on to newer games still recall Contra fondly; Jami writes: The Gears of War trilogy on 360 is my favorite co-op currently, although I do have fond memories of bonding with my brother playing some co-op Contra on the NES.

• Windows NT workstation on AD domain

  - by Tom

  We run a Windows NT workstation connected to special manufacturing equipment, that everyone is deathly afraid to touch. It has custom software and special cards inside of the machine, making a rebuild impossible. The problem is, we are migrating to an AD domain from an NT domain, and this workstation stills needs access to storage on the network (AD computers). How should I go about doing this, after we get rid of our NT Domain controller? Upgrading to 2000 is not an option (so says management). I know, I know, if it dies we are in trouble. But that's managements choice, we just need to get rid of this NT domain.

• Log centralization, display, transport and aggregation at scale v2

  - by Eric DANNIELOU

  This is a duplicate question of Log transport and aggregation at scale and http://stackoverflow.com/questions/1737693/whats-the-best-practice-for-centralised-logging, but the answers might differ now : The softwares described in 2009 may have changed since (for example Octopussy evolved from version 0.9 to 1.0.5). Rsyslog has become the default on most linux distro. Requirements have changed (security, software configuration management, ...). I'd like to ask the following questions : How do you centralize, display and archive system logs? How would you like to do it now if you had to? Most linux distro use rsyslog nowadays, which can provide reliable log transport. But some older unices, network devices and maybe windows box still use old udp rfc-style transport. How did you manage to get reliable transport? Storing logs for a few months can represent a huge amount of disk space. How do you store them? rdbms? Compressed and encrypted text files?

• Turnkeylinux lampp guest doesn't have internet connection

  - by dave08

  I've set up a turnkeylinux lampp server in virtualbox with two network bridged connections, one for when I'm plugged in to my router, and one for when I'm using a wireless connection. This allowed me to pull up the turnkey control panel on the host machine's browser, but when I try going into the command prompt in the guest and run an apt-get update, it doesn't seem to have an internet connection, even though it seems to have a connection with the host. What could be wrong? Thank you very much in advance for any answers...!
