• JUDCon 2013 Trip Report

  - by reza_rahman

  JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

• Get to Know a Candidate (11 of 25): Roseanne Barr&ndash;Peace &amp; Freedom Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Barr is an American actress, comedienne, writer, television producer, and director.  Barr began her career in stand-up comedy at clubs before gaining fame for her role in the sitcom Roseanne. The show was a hit and lasted nine seasons, from 1988 to 1997. She won both an Emmy Award and a Golden Globe Award for Best Actress for her work on the show. Barr had crafted a "fierce working-class domestic goddess" persona in the eight years preceding her sitcom and wanted to do a realistic show about a strong mother who was not a victim of patriarchal consumerism. The granddaughter of immigrants from Europe and Russia, Barr was the oldest of four children in a working-class Jewish Salt Lake City family; she was also active in the LDS Church. In 1974 she married Bill Pentland, with whom she had three children, before divorcing in 1990 and marrying comedian Tom Arnold for four years. Controversy arose when she sang "The Star-Spangled Banner" off-key at a 1990 nationally aired baseball game, followed by grabbing her crotch and spitting. After her sitcom ended, she launched her own talk show, The Roseanne Show, which aired from 1998 to 2000. In 2005, she returned to stand-up comedy with a world tour. In 2011, she starred in an unscripted TV show, Roseanne's Nuts that lasted from July to September of that year, about her life on a Hawaiian farm. The Peace and Freedom Party (PFP) is a nationally-organized political party with affiliates in more than a dozen states, including California, Florida, Colorado and Hawaii. Its first candidates appeared on the ballot in 1966, but the Peace and Freedom Party of California was founded on June 23, 1967, after the LAPD riot in the wealthy Century City section of Los Angeles, and qualified for the ballot in January 1968.  The Peace and Freedom Party went national in 1968 as a left-wing organization opposed to the Vietnam War. From its inception, Peace and Freedom Party has been a left-wing political organization. It is a strong advocate of protecting the environment from pollution and nuclear waste. It advocates personal liberties and universal, high quality and free access to education and health care. Its understanding of socialism includes a socialist economy, where industries, financial institutions, and natural resources are owned by the people as a whole and democratically managed by the people who work in them and use them. Barr is on the Ballot in: CA, CO, FL Learn more about Roseanne Barr and Peace and Freedom Party on Wikipedia.

• How to run a local and external website on same computer with 2 NIC's, 2 Routers and 3 seperate networks?

  - by CandN

  Hello and hopefully I can get some answers to my question, though I think I'm making it more complicated for myself than it has to be. My business is a used auto dealership, and I'm in the process of connecting it to the world - via ethernet from the business server [running Xubuntu] to the ISP's ethernet router/modem, so that I can host our own website (no more than 5-10 people probably visiting at any time - mainly paying their bill), as well as set up a web based internal-intranet site - via DD-WRT Router on the 2nd NIC on the business server - that'll be accessed over Wifi from employees personal devices. On the other end of this is trying to offer free wifi to customers that is completely seperate of the 2 mentioned above networks. Quick Rundown: 1. Web Site for Customers to access. I'm going to use no-ip.org for DNS for the moment being, so I'll have a site that customers can access from anywhere in the world at "mybiz.no-ip.org". This will be forwarded to NIC #1 on the server, possibly at an address like "108.69.." as its being provided an IP from the ISP's modem/router, that is from Time Warner, and they allow NO! configuration options. Web Site for employees to access. I'm trying not to use the server too much as a desktop, only for critical situations, so having a backend thats seperate from the front-facing website is critical. This will be the DD-WRT router hardwired into NIC #2 on the server. This WiFi will be password accessible. Public WiFi for customers. The DD-WRT can seperate networks if I'm correct, I just can't seem to understand how to seperate the 2 and still have internet access on both. I've done it before, but the "Public" wifi (with no password set to connect) kept dropping the connection like a problem was happening that I couldn't figure out. So if I could do a little drawing, this is how it would/should possibly look. ISP -- [Sends Public Facing IP of 108.69.*.1/8] -- ISP Modem Router ISP Modem Router (Ethernet Only) -- [Gives Private IP 108.69.*.2] -- Server NIC #1 Server NIC #1 -- [Gives Private IP 108.69.*.3] -- DD-WRT Router DD-WRT Router -- [DHCP Enabled Giving IP's 172.16.0.0/16] -- Employees Network | | --------- [DHCP Enabled Giving IP's 192.168.1.0/24] -- Public WIFI Hope it's not too confusing, but it anyone could give me some good direct tutorials on how to accomplish this, or if YOU know, then it'll be alot of help. Thanks to all in advance. Need anything else to be explained? Don't hesitate to ask! *Using The LAMP stack with Webmin/VirtualMin -Customer site is located in /var/www2/ -Private Employees site is located in /var/www/ Using no-ip.org's dynamic client updater

• Server-infrastructure recommendations

  - by Tim van Elsloo

  Here's the thing: I need a cheap, fast, reliable infrastructure that can dynamically scale (like Amazon S3: cloud-storage). I'm thinking of 3 different type of 'servers'. Application-server Should be able to run CentOS (or another light Linux-distr.) Should be able to run Apache Should be able to run PHP Should be able to run GD (so it does rely on it's cpu). Should be extremely reliable and fast. Database-server Should be able to run MySQL Should be able to... well, do nothing else :P. Should be extremely reliable and fast. Storage-server Should be able to run some kind of file-transfer-deamon (like FTP, CouchDB, etc.) Should be able to do nothing else. Should be extremely reliable and fast. So technically, by transferring all static data to 2 different servers/services, the application-server can totally focus on the webpages. My questions: What services do you recommend? Which is cheaper, faster and more reliable: using my own server, or using some cloud-storage/cloud-computing-service (like Amazon S3, CloudFiles, etc.)? How can I prevent bandwidth abuse (such as dos-attacks causing the bill to be extremely high)? What's the difference between "including CDN" and "excluding CDN"? It seems the price doesn't differ at CloudFiles? Do you have to pay "including CDN" + "excluding CDN" when you decide to enable the delivery-network? Or have you only got to pay "including CDN"? Should I use my own nameserver too or can I use my domain-hoster's nameservers? What are the minimum software specifications of a nameserver. Can I write some software myself? Does anyone have a good protocol-description? I hope you can answer my questions. Answers I shouldn't write my own nameserver-software. Instead, I should use something like bind. (http://osspro.com/2010/05/04/linux-create-your-own-domain-name-server-dns/).

• Big Companies Influence Retail in 2010

  - by David Dorf

  From a retail industry perspective, 2010 will go down as the year mobile went mainstream, the economy recovered from the crash, and Facebook surpassed Google as the most influential online property. While the economy certainly had the biggest impact on the retail industry, a few big companies also exerted influence. Here's a rundown and a look back at 2010: Apple -- Steve Jobs and company continued to lead the mobile pack. Consumers are using their iPhones to shop, retailers are using the iPod Touch for mobile checkout, and both are embracing the iPad as the next wave of technology. The Next Technology from Apple Mobile Platforms in Retail Apple Stores, Touch2Systems, and the iPad Google -- Not to be outdone, Google's Android platform grew faster than Apple's, plus they support QRCodes natively and will probably beat Apple to NFC. Google Checkout, Product Search, and Boutiques.com continue to impact the e-commerce scene. Google Leverages Like.com Facebook -- While the movie The Social Network certainly made Facebook a household name, Connect, Places, and seeing the "like" button all over the Web really pushed Facebook everywhere. 2010 set the foundations for f-commerce. Facebook Participatory Promotions Crowd Savers What's the value of a Facebook fan? Step Aside Google Leveraging Social Networks for Retail Social Shopping at Nine West Groupon -- This newcomer executed on a simple concept flawlessly, making them the fasted company to reach $1B in revenue. (See cool chart from Silicon Alley Insider.) Google's offer of $5-6B wasn't enough, so now they are raising an additional $1B in funding, presumably to buy-up all the copycats across the globe. Changing the Way We Shop Amazon -- As if leading the e-commerce charge wasn't enough, Amazon shook things up with their purchase of Woot and release of their Price Checker mobile app. They continue to push boundaries with Kindle, and don't seem worried about the iPad at all. You Can't Win on Price Amazon Looks at Your Social Graph eBay -- Acquiring Skype didn't exactly work out, but eBay's purchase of PayPal and RedLaser are driving the company forward. They are still a major force. Bump the Bill Oracle, SAP, HP, IBM, and Cisco left their marks on the retail industry as well with various acquisitions and CxO shake-ups. We'll just have to wait and see what 2011 brings next.

• Are there new flexible texteditors? [closed]

  - by RParadox

  Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

• How can the little guys effectively learn and use puppet?

  - by drumfire

  Six months ago, in our not-for-profit project we decided to start migrating our system management to a Puppet controlled environment because we are expecting our number of servers to grow substantially between now and a year from now. Since the decision has been made our IT guys have become a bit too annoyed a bit too often. Their biggest objections are: "We're not programmers, we're sysadmins"; Modules are available online but many differ from one another; wheels are being reinvented too often, how do you decide which one fits the bill; Code in our repo is not transparent enough, to find how something works they have to recurse through manifests and modules they might have even written themselves a while ago; One new daemon requires writing a new module, conventions have to be similar to other modules, a difficult process; "Let's just run it and see how it works" Tons of hardly known 'extensions' in community modules: 'trocla', 'augeas', 'hiera'... how can our sysadmins keep track? I can see why a large organisation would dispatch their sysadmins to puppet courses to become puppet masters. But how would smaller players get to learn puppet to a professional level if they do not go to courses and basically learn it via their browser and editor?

• What can I do to lower bandwidth cost on a bandwidth heavy site?

  - by acidzombie24

  The easiest answer is CDN but I'd like to ask. A friend of mine has a server that is used for mirror downloads. He says he is doing about 10TB of bandwidth a month which shocked me (I wonder if he is lying). I seen his site and he has no ads. I suspect he might close his website once he gets the bill. Anyways I was wondering since his CPU/RAM is not being used and his HD usage is around 15gb what he can do to lower cost if he continues this site. I said put up ads but I don't know if ads would cover it I found one CDN which offers $0.070 / GB. 10240gb (10TB) * .07 = $717 a month. That seems a little steep but he is using lots of traffic due to it being a mirror site. Also using a CDN doesnt make sense as he doesn't need multiple servers hosting the files in different areas (which is one reason he isn't using that now). He just needs a big upload pipe Is there something he can do? At the moment he is paying $200 a month on a dedicated server and he is using WAY more bandwidth then he should be using. Side question: Can gz-ing files large already compressed files help? like on (zip, rars, etc)

• Speeding up Outlook Express on Windows XP over satellite

  - by John

  My brother is in the field with Doctors Without Borders. I'm posting this question on his behalf. We use outlook express (on a pc running windows XP) and a 9600 baud dial up satellite phone modem to get our email direct from the server in Paris. As this is a very expensive way to communicate (our satellite bill is $50K a year, no joke), it seems like trying to streamline is a good idea. Here's the question- when we connect, the sequence goes: Send outbox mails. This goes pretty quickly, probably 10-15 seconds for each email, up to maybe a couple minutes for an email of 150k or so). The status bar moves pretty quickly, according to the emails sent. The system then says "Checking for new messages on (our account name), and "Receiving list of messages from server". This takes a long time. Like 10-15 minutes. The status bar crawls along. Then it receives the messages. "Receiving messages from server". Again, each message takes 10-15 seconds, and this part moves along reasonably fast. I'm curious as to what is going on in the second part. It takes forever, and doesn't seem to be part of the sending or receiving messages themselves. Is there a way to speed up the process by changing a preference with communicating with the server or something? Does anyone have any advice for him speeding up what Outlooks Express is doing? Obviously his software is ancient and adding more software is not realistic based on the connection speed. Thanks!

• Which server software and configuration to retrieve from multiple POP servers, routing by address to correct user

  - by rolinger

  I am setting up a small email server on a Debian machine, which needs to pick up mail from a variety of POP servers and figure out who to send it to from the address, but I'm not clear what software will do what I need, although it seems like a very simple question! For example, I have 2 users, Alice and Bob. Any email to [email protected] ([email protected] etc) should go to Alice, all other mail to domain.example.com should go to Bob. Any email to [email protected] should go to Bob, and [email protected] should go to Alice Anything to *@bobs.place.com should go to Bob And so on... The idea is to pull together a load of mail addresses that have built up over the years and present them all as a single mailbox for Bob and another one for Alice. I'm expecting something like Postfix + Dovecot + Amavis + Spamassassin + Squirrelmail to fit the bill, but I'm not sure where the above comes in, can Postfix deal with it as a set of defined regular expressions, or is it a job for Amavis, or something else entirely? Do I need fetchmail in this mix, or is its role now included in one of the other components above. I think of it as content-filtering, but everything I read about content-filtering is focussed on detecting spam rather than routing email.

• Reduce power consumption of gaming computer while idle

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 clocked @ 3.3 Ghz 3x DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 oc'd at 800/1600/1850 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) I've already seen this post Reduce power use on computer and this post How do I lower power consumption of my computer and while useful, I'm looking for answers specific to my build and OS. I'm pretty sure this build is a energy-intensive build by default, but I want to try to reduce the amount of energy my build uses when I leave it idle (when I go to bed or go out, etc). The first requirement for this machine is that I need to leave it on, so I cannot turn it off while it's being unused. I run it as a file server for personal reasons and I also leave it on in case people leave me messages on various IM services and chat clients (IRC, MSN, Steam, XFire, Pidgin, etc). I'm also unable to replace the parts in my computer with a cheaper "greener" part. What are some ways to minimize the amount of power the machine uses? I'm already using a high efficiency power supply (80 Plus Gold), but I imagine there's other things that can be done in the BIOS and Windows' power settings to reduce power usage while I'm not using the computer. From what I can tell, I can't use Sleep since that'll disable network access (whole reason why I leave the computer on in the first place). I already turn off my monitor when it's not in use. I enabled Intel SpeedStep within the BIOS (I know, I have a 965 and why am I enabling SpeedStep?) Should I bring the graphics card back to stock speeds and lower the clock on the processor even more? Main reason why I'm asking is I think this computer alone is the reason why my power bill is high, so I want to reduce its consumption to as low as possible without having to shut the thing down.

• Free tiered storage automation in linux?

  - by NginUS

  I have a couple virtualized fileservers running in QEMU/KVM on ProxmoxVE. The physical host has 4 storage tiers with significant performance variances. They're attached both locally and via NFS. These will be provided to the fileserver(s) as local disks, abstracted into pools, and handling multiple streams of data for the network. My aim is for this abstraction layer to intelligently pool the tiers. There's a similar post on the site here: Home-brew automatic tiered storage solutions with Linux? (Memory - SSD - HDD - remote storage) in which the accepted answer was a suggestion to abandon a linux solution for NexentaStor. I like the idea of running NexentaStor. It almost fits the bill. NexentaStor provides Hybrid Storage Pools, and I love the idea of checksumming. 16TB without incurring licensing fees is a huge plus as well. After the expense of the hardware, free is about all my budget can handle. I don't know if zfs pools are adaptive or dynamically allocated based on load, but it becomes irrelevant since NexentaStor doesn't support virtio network or block drivers, which is a must in my environment. Then I saw a commercial solution called SmartMove: http://www.enigmadata.com/smartmove.html And it looks like a step in the right direction, but I'm so broke I'd be wasting their time to even ask for a quote, so I'm looking for another option. I'm after a linux implementation that supports virtio drivers, and I'm at a loss as to which software is up to it.

• Processing-time billing in Amazon EC2

  - by Rafael Almeida

  Hi all! I think my question is fairly basic, but I would like a clarification: in the Pricing part of AWS we can see that Amazon charges people around .10 by the 'instance computing hour'. I've seen in a blog post somewhere (can't remember where exactly, and even if I did I think it was in Portuguese anyway) that this way your minimum monthly payment would be $72 (= .10 $s/hour x 24 hours x 30 days). Is this correct? (I don't think it is!) In my understanding is that this 'virtual computing time' is only used when your machine is actually doing something (serving pages, serving the admin via ssh, whatever), so real billable usage would be less than 720 hours/month in most webserver scenarios. Is my view correct? If it is, then it leads me to another question: is it economically interesting to buy access to one of these instances for testing? I mean, would I have the 'freedom' to 'forget' about it for a month and receive a very-close-to-zero (as in, a few cents) bill? Do you do it/know of anybody who does? Any thoughts on the matter (as in, "yes, it's a good idea", or "yes, but there's this 'gotcha': ...", or "no, nobody does it because of...")? PS: sorry for the loong question text. I highlighted the main questions for easy view. Also, I'm not sure if this question is actually more than one and if it's desirable for the community, so, sorry if it is too! Thanks in advance!

• On what should i not be pennywise buying a machine for SqlServer 2008?

  - by Michel

  Hi, i'm going to do a project for a client and i'll be hosting the database server myself. Normally it would be on my dev machine, but there will also be data pushed into it during developing and testing, so i would like to setup a dedicated test sql server. But, as you might guess, i can't afford to go to Dell and buy one mega 16 core 16 GIG 10 TB raid 5 machine (wow, that sounds cool) So i have to save the money somewhere... the hardware only has to live for a year (longer is nice of course), and the sql server won't be hit too hard: i guess the average server will only see it as a cough once in a while. But i do want the machine to be a bit performant: if it does get some data, it must be a bit responsive. So my question is were can i leave out the expensive parts: is 2 GB enough, or must i take 4GB, is an average processor enough or should it be a top of the bill? Is Sql server a large resource user or is a simple desktop pc good enough? It wil run on win2008 by the way.

• Using my old PC as a web/file server?

  - by Garrett

  I have an old desktop computer that I've been trying to sell for AGES. I guess nobody is looking for computers because it was advertised at a dirt cheap price on craigslist, local papers, etc. Anyways, I was wondering if it would be worth it to set it up as a home file server, a web dev server (I have a web host for actual production use), and maybe host a few server applications (ex: ventrillo). The computer is actually an old Dell that I cannibalized after the motherboard being destroyed by lightning, so it has fairly new parts in it. The specs are: P4 3.4GHz w/ HT and Artic Cooling Freezer 7 3GB DDR2 533 RAM 80GB hdd (will upgrade the hard drive if it's even worth using as a server) basic dvd rom 430 Watt Thermaltake PSU (it might be important to note that it is only 60% efficiency) ATI Radeon x600 256MB Antec 300 case It's not a really beefy machine, I just can't see giving it away or putting it in the corner to just collect dust. I have Windows Server 2008 R2 Standard and I am confident in my skills in operating most Linux operating systems. I'd also be using it to tinker with when I learn new things in my server admin classes (I'm finishing my 2nd year in college at the moment so I'm still learning) Also, my house is quite old and the electrical wiring is pretty poor (it MIGHT be up to code, then again, where I live most people don't even know what regulations are or let alone know how to spell it...) Would it be safe to leave it running all day and is it going to run up my electric bill because of the PSU efficiency? I only have 5mbit cable internet, but I won't be running very bandwidth intense services on it so it should be ok. I should elaborate on why I am concerned about the power. The circuits should be fine, but I'm more concerned about fire hazard. What is the likelihood that the server could cause an electrical fire? Again, thank you all for the feedback!

• RAM ok in memtest86+ == RAM ok after wake from sleep?

  - by twon33

  I have a Windows XP (32-bit) system that appears stable in normal operation, but was repeatably freezing (hard lock, no BSOD) a minute or so after waking from S3 sleep. Some Googling against the motherboard model and memory manufacturer suggested that I might need to bump up the memory voltage, so I tried it and it now seems to resume without freezing. However, I don't really trust it and I'd like to validate that it's actually stable, especially after resuming from sleep. I've run Prime95 for a few hours with no issues, and am planning an overnight run of Memtest86+, which I expect to pass because the system has been solid whenever I've run it without putting it to sleep. Does something like Memtest86+ exist that actually invokes S3 sleep during operation? Clearly it would need an operator to wake the computer to resume testing, but I don't think I've ever heard of a memory test tool that can do this. Alternately, am I wasting my time? Should a clean bill of health from Memtest86+ indicate stability regardless of whether sleep is involved, or, conversely, does my original problem indicate that Memtest86+ would have failed eventually with the stock voltage if I'd run it, sleep or not?

• GlusterFS as elastic file storage?

  - by Christopher Vanderlinden

  Is there any way to run GlusterFS in a replicated mode, but with the ability to dynamically scale the volume up and down? Say you have 3 servers all running glusterd. your Gluster volume would have to be setup with replica 3 gluster volume create test-volume replica 3 192.168.0.150:/test-volume 192.168.0.151:/test-volume 192.168.0.152:/test-volume You would then mount it as say \mnt\gfs_test What happens when I want to add 2 more servers to the storage pool and then also use them in this volume? Is there any easy way to expand the volume AND increase that replica count to 5? My end goal is to run this on EC2 instances, say 3 Apache front ends, with the webroot setup on the gluster volume mount. My concern is that if I ever need to spin up a server, I would want the server to not only be an additional Apache front end, but also another server in the gluster file system, adding to fault tolerance as well as possibly giving a slight boost in read speed. Maybe there are better options that would fit the bill here? Thanks.

• Transferring domain from one registrar to another

  - by Macha

  I have a domain from my old web host, which was free with my hosting account. After a few years, I am moving to a VPS. Most of my other domains were registered with Namecheap, so it was just a matter of changing a few DNS records. However, given that my old host does not provide me with a DNS control panel, and I don't want to be paying a full hosting bill for just domains, I'm now looking into transferring it. My old host says there will be a charge of $15 to them. NameCheap's page seems to imply you don't need the current registrar to do anything, but it also seems to be based on sending an email to the one listed in whois. Of course, my old host have whoisguard on the domain so the only email on it is [email protected] (and not a unique [email protected], just [email protected]) which doesn't go to me. Again, there doesn't seem to be an option to disable this. So, is it a case of paying my old host's fee, and paying again for the domain from NameCheap, or is there some other way to transfer my domain? (I'm not really sure which of the trilogy sites this is best for.)

• Using udev to create a character device based on a driver being loaded

  - by SteveCB

  I'm in the process of setting up RAID monitoring for a number of Dell servers that use the PERC 6i integrated card. We're using Nagios at present and the check_megasasctl plugin seems to fit the bill. However, the plugin relies upon the existence of: /dev/megaraid_sas_ioctl_node This device node doesn't exist by default, you have to create it by hand using something like: mknod /dev/megaraid_sas_ioctl_node c 253 0 Now, to make the existence of this device node persistent across reboots, I thought I could write a udev rule, but as usual, I'm missing something. I thought I could create a file such as /etc/udev/rules.d/10-local/rules that contained: DRIVER=="megasas" NAME="megaraid_sas_ioctl_node" MODE="0600" But this doesn't work - no device node after a reboot. Dmesg output indicates the megasas driver is loaded and functional: megasas: 00.00.04.01-RH1 Thu July 10 09:41:51 PST 2008 megasas: 0x1000:0x0060:0x1028:0x1f0c: bus 1:slot 0:func 0 megasas: FW now in Ready state Further, I don't see any means to instruct udev on which type of device node to create: character or block. I suspect I'm failing to understand exactly how udev is meant to work. I realise I could just cheat and run MegaCLI in /etc/rc.local, redirecting output to /dev/null; it creates the megaraid_sas_ioctl_node device node as part of its execution. I just thought using udev rules would be a) cleaner and b) a useful learning exercise. Perhaps I should just dump the above mknod command in /etc/rc.local... So how do I get udev to create the /dev/megaraid_sas_ioctl_node device node based on the presence of the megasas driver? Cheers Steve

• Linux file server for an inexperienced admin

  - by Pat

  A charity I volunteer for wants a file server for their mostly Windows machines (about five XP and 7 machines, with some Mac laptops every now and then). For the server, I have a PC with an Intel Core 2 Duo 3GHz proc, 4GB of DDR2 400MHz RAM, and a 500 GB HDD. (I should point out that they do not currently have any server - they are just using Windows to share a folder on one of the PCs.) What is a linux distro that is easy to configure for Windows file serving yet stable and secure enough to protect sensitive data without an expert sysadmin? I'm guessing that a Debian distro would probably fit the security bill, but I don't know of any tailored to novice sysadmins. Also, are there any killer apps for making this easy to administer and set up (as a Windows file server, in particular - this answer is a good example)? Would FreeNAS be sufficient? Once it's all set up, what are the minimum measures I need to take to keep the data secure? I found this somewhat helpful answer, but it's not specific to my question of just getting a secure file server up, running, and maintained.
