  • how to map sub domain to amazon ec2 and main domain mapped to shared hosting

    - by user330415
    I am trying to map subdomain to amazon ec2 with elastic IP. I already mapped the www.xxxexample.com to my shared hosting by giving the dns server name (ns1.justhost.com). And I created a many subdomains using the cpanel of shared hosting. Shared hosting is working fine. Amazon route53 is a paid service. So I dont want to use that service. I want to map my subdomain points to amazon ec2 instance and main domain already primarily mapped to shared hosting. I tried from the below example, nothing worked for me, getting my domain name to point to my amazon ec2 instance Can anybody help me to get rid of this issue?? Thanks in advance.

  • Wildcard 'A' record overriding CNAME record

    - by user116890
    I have a Wildcard * A record for self-registration of subdomains by users on our web app. All works fine. I now need to set up an alias for support.mydomain.com to point to mydomain.freshdesk.com. I created a CNAME record as per instructions however it appears my Wildcard A record is overriding the CNAME entry. Any thoughts on how to resolve this? I need the wildcard so creating an A record for each user subdomain is not possible. Thanks.

  • The Evolution of Television and Home Entertainment

    - by Bill Evjen
    This is a group that is focused on entertainment in the aviation industry. I am attending their conference for the first time as it relates to my job at Swank Motion Pictures and what we do for our various markets. I will post my notes here. The Evolution of Television and Home Entertainment by Patrick Cosson, Veebeam TV has been the center of living rooms for sometime. Conversations and culture evolve around the TV. The way we consume this content has dramatically been changing. After TV, we had the MTV revolution of TV. It has created shorter attention spans, it made us more materialistic, narcissistic, and not easily impressed. Then we came to the Internet. The amount of content has expanded. It contains a ton of user-generated content, provides filtering, organization, distribution. We now have a problem. We are in the age of digital excess. We can access whatever we want. In conjunction with this – we are moving. The challenge we have now is curation. The trends  we see: rapid shift from scheduled to on demand consumption. A move to Internet protocols from cable Rapid fragmentation of media a transition from the TV set to a variety of screens Social connections bring mediators and amplifiers. TiVo – the shift to on demand It is because of a time-crunch Provides personal experiences Once old consumption habits are changed, there is no way back! Experiences are that people are loading up content and then bringing it with them on planes, to hotels, etc. Rapid fragmentation of media sources Many new professional content sources and channels, the rise of digital distribution, and the rise of user-generated content contribute to the wealth of content sources and abundant choice. Netflix, BBC iPlayer, hulu, Pandora, iTunes, Amazon Video, Vudu, Voddler, Spotify (these companies didn’t exist 5 years ago). People now expect this kind of consumption. People are now thinking how to deliver all these tools. Transition from the TV set to multi-screens The TV screen has traditionally been the dominant consumption screen for TV and video. Now the PC, game consoles, and various mobile devices are rapidly becoming common video devices. Multi-screens are now the norm. Social connections becoming key mediators What increasingly funnels traffic on the web, social networking enablers, will become an integral part of the discovery, consumption and sharing model for Television. The revolution will be broadcasted on Facebook and Twitter. There is business disruption There are a lot of new entrants Rapid internationalization Increasing competition from existing media players A fragmenting audience base Web browser Freedom to access any site The fight over the walled garden Most devices are not powerful enough to support a full browser PC will always be present in the living room Wireless link between PC and TV Output 1080p, plays anything, secure Key players and their challenges Services Internet media is increasingly interconnected to social media and publicly shared UGC Content delivery moving to IPTV Rights management issues are creating silos and hindering a great user experience and growth Devices Devices are becoming people’s windows into all kinds of media from all kinds of sources There won’t be a consolidation of the device landscape, rather the opposite Finding the right niche makes the most sense. We are moving to an on demand world of streaming world. People want full access to anything.

Following are my requirements Shared Windows hosting Should be cheap in price Should have at least one SQL server Db and one mysql db. Should support atleast asp.net 3.5 and php Will be good if it has support for asp.net mvc (no problem even if it is not available also) Should be able to install third party blog sites. Bandwidth, total space and performance are not very important. Silverlight is also an added advantage (no problem even if it is not available also). There should be no advertisement or banner added by the hosting company in the site. Should have support for subdomains

  • Ubuntu, apache2 wildcard dns to subdomain

    - by Mark van Velthoven
    Currently I'm hosting my own (ubuntu) server with the following services: samba, ftp and a webserver. I've bought a domain and linked the DNS A-record to my ISP's IP. This is working correctly. Now I'd like to use the DNS wildcard-record to create subdomains. I want to avoid waiting 24hrs before the DNS change completes. Thusfar I'm only able to redirect all incoming wildcards to the same directory: test1.domain.com redirects to /var/www test2.domain.com redirects to /var/www Although I'd like to get: test1.domain.com redirects to /var/www/test1 test2.domain.com redirects to /var/www/test2 My guess would be to change the file /etc/apache2/sites-available/domain. Any help or tips would be welcome! Thanks, Mark

  • Economical DNS hosting separate from local registrar for country specific TLDs - email or web hosting not required

    - by Eric Nguyen
    Our company owns many country specific top level domains (TLDs; .sg, .my). We will purchase more for other countries in all South East Asia. These domains are associated with our websites hosted on Amazon EC2. The DNS records are currently hosted on a dedicated server that will shut down tomorrow. (The name servers are set to the ones of a web hosting company) Therefore, I will need to host the DNS records somewhere else. Hosting the DNS records with the local registrar costs SGD18 a year per domain in addition to the domain price (which is already very expensive but we have no choice). It would be convenience to host DNS recors for all the country specific TLDs we have using a single service, separate from the local registrars from which we bought the domains. A few searches prompted examples like Amazon Route 53 and dnsmadeeasy.com and the likes. However, since I'm only concern about the country specific TLDs, not .com 1) Is it really economical to host DNS records of all domains in 1 single place as described above? (Have the relevant countries and/or the local registrars done something to keep their monopoly and always charges ridiculous prices for their country specific TLDs?) 2) I would imagine I will need to tell the local registrars to update the name servers to those of the DNS hosting service provider e.g. dnsmadeeasy.com here. Am I correct about how it works here? 3) Will I be able point the TLDs themselves to IP addresses I desire (the EC2 instances where my websites are) or will I only able to do so with the subdomains? 4) Are there any drawbacks that I should know here? Background about our needs: We need the websites associated with the country TLDs to be up and running all the times Also, we'll need to be able to add/edit A and CNAME records We use Google Apps for Business for internal email so I will need to be able to add/edit MX records and TXT records

  • SQL Azure: Notes on Building a Shard Technology

    - by Herve Roggero
    In Chapter 10 of the book on SQL Azure (http://www.apress.com/book/view/9781430229612) I am co-authoring, I am digging deeper in what it takes to write a Shard. It's actually a pretty cool exercise, and I wanted to share some thoughts on how I am designing the technology. A Shard is a technology that spreads the load of database requests over multiple databases, as transparently as possible. The type of shard I am building is called a Vertical Partition Shard  (VPS). A VPS is a mechanism by which the data is stored in one or more databases behind the scenes, but your code has no idea at design time which data is in which database. It's like having a mini cloud for records instead of services. Imagine you have three SQL Azure databases that have the same schema (DB1, DB2 and DB3), you would like to issue a SELECT * FROM Users on all three databases, concatenate the results into a single resultset, and order by last name. Imagine you want to ensure your code doesn't need to change if you add a new database to the shard (DB4). Now imagine that you want to make sure all three databases are queried at the same time, in a multi-threaded manner so your code doesn't have to wait for three database calls sequentially. Then, imagine you would like to obtain a breadcrumb (in the form of a new, virtual column) that gives you a hint as to which database a record came from, so that you could update it if needed. Now imagine all that is done through the standard SqlClient library... and you have the Shard I am currently building. Here are some lessons learned and techniques I am using with this shard: Parellel Processing: Querying databases in parallel is not too hard using the Task Parallel Library; all you need is to lock your resources when needed Deleting/Updating Data: That's not too bad either as long as you have a breadcrumb. However it becomes more difficult if you need to update a single record and you don't know in which database it is. Inserting Data: I am using a round-robin approach in which each new insert request is directed to the next database in the shard. Not sure how to deal with Bulk Loads just yet... Shard Databases:  I use a static collection of SqlConnection objects which needs to be loaded once; from there on all the Shard commands use this collection Extension Methods: In order to make it look like the Shard commands are part of the SqlClient class I use extension methods. For example I added ExecuteShardQuery and ExecuteShardNonQuery methods to SqlClient. Exceptions: Capturing exceptions in a multi-threaded code is interesting... but I kept it simple for now. I am using the ConcurrentQueue to store my exceptions. Database GUID: Every database in the shard is given a GUID, which is calculated based on the connection string's values. DataTable. The Shard methods return a DataTable object which can be bound to objects.  I will be sharing the code soon as an open-source project in CodePlex. Please stay tuned on twitter to know when it will be available (@hroggero). Or check www.bluesyntax.net for updates on the shard. Thanks!

  • How can I move a load of zone records from a web based system to text based one?

    - by Chris Adams
    Hi there, I have a few domains with Dreamhost where I have set a load of records using their web based domain name system, and I've like to move them to another provider that lets me enter info directly as a text file for their name server, bind 9 to use. (If you're interested, I'm moving them to Gandi.net). Previously when I used a cpanel based system to do something similar, there was a tool that let me simply enter a domain name, and any available domains were automagically entered into a system, saving me typing it myself (and bringing down sites with silly typos in the process). What open source tool can I use to query a domain for all the relevant subdomains and records and list them in a format like a zone file, that I can use with other name servers?

  • Using IIS7 as a reverse proxy

    - by Jon
    Hi All, My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy. http://serverfault.com/questions/55309/using-iis7-as-a-reverse-proxy I need to have IIS the main site and linux (Apache) being the proxied site(s). so I have site1.com (IIS7) site2.com (Linux Apache) they have subdomains of sub1.site1.com sub2.site1.com sub3.site2.com I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how). I can not have it running as Apache doing the proxying as I need IIS exposed directly. any and all advice would be great. Thanks

  • Two different domains as one user session

    - by Mathew Foscarini
    I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.

  • php.ini use multiple include paths - openbasedir restriction

    - by hfidgen
    I need to allow an include path for a vhost subdomain on Plesk 10. I've edited the PHP PEAR path into /etc/php.ini as I'm happy for it to be globally available: include_path = ".:/usr/share/pear/" This works insofar as PHP is able to see the files in that directory when a script tries to include them, but I'm getting the dreaded openbasedir error: Warning: require_once() [function.require-once]: open_basedir restriction in effect. File(/usr/share/pear/xxxx.php) is not within the allowed path(s): (/var/www/vhosts/xxxx.com/subdomains/test/httpdocs/:/tmp/) Am I right in saying that the subdomain or main domain can have a vhost.conf file in which I can alter the openbasedir allowed paths? I've tried searching out solutions but I'm afraid I can't quite see one yet :)

  • Routing to various node.js servers on same machine

    - by Dtang
    I'd like to set up multiple node.js servers on the same machine (but listening on different ports) for different projects (so I can pull any down to edit code without affecting the others). However I want to be able to access these web apps from a browser without typing in the port number, and instead map different urls to different ports: e.g. 45.23.12.01/app - 45.23.12.01:8001. I've considered using node-http-proxy for this, but it doesn't yet support SSL. My hunch is that nginx might be the most suitable. I've never set up nginx before - what configuration do I need to do? The examples of config files I've seen only deal with subdomains, which I don't have. Alternatively, is there a better (stable, hassle-free) way of hosting multiple apps under the same IP address?

  • Hyper-V Live Migration across Sites!

    - by Ryan Roussel
    One of the great sessions I sat in on at Tech Ed this week was stretching a Windows 2008 R2 Hyper-V  Failover Cluster across sites.  With this ability, you could actually implement a Hyper-V cluster where you could migrate or even Live Migrate VMs across sites.   With this area’s propensity for Hurricanes, this will be a very popular topic for me over the next few months. While this technology is possible today, it’s also very complicated and can be very expensive to implement.    First your WAN connection has to support the ability to trunk your VLAN across both sites in order to Live Migrate.  This means you can’t use a Layer 3 routed connection like MPLS.  It has to be a Metro Ethernet connection or "Dark Fiber”.  Dark Fiber is unused Fiber already in the ground that can be leased from  various providers. Both of these connections would allow you to trunk layer 2 across your WAN.  Cisco does have the ability to trunk layer 2 across a routed connection by muxing the traffic but this is only available in their Nexus product line which has a very steep price tag.   If you are stuck with MPLS or the like and Nexus switching is not a realistic possibility, you will have to implement a multi-subnet cluster in which case Live Migration won’t be possible.  However you can still failover VMs to the remote site with some planning and manual intervention.  The consideration here is that the VMs will be on a different subnet once migrated, so you will have to change the IP addressing of your VMs.  This also has ramifications with DNS and Name resolution to control your down time.  DHCP with Reservations for your VMs is the preferred method to achieve the IP changes as this will automate that part of the process.   Secondly, you will have to have  a mechanism to replicate your storage across both sites.  Many SAN vendors natively support hardware based synchronous and asynchronous replication.  Some even support cluster shared volumes which were introduced in 2008 R2.   If your SANs do not support this natively, there are alternative file based replication products either software based like Double Take or hardware appliance like EMC.  Be sure to check with your vendor on the support of Disk majority if you’re replicating your quorum disk between SANs.   The last consideration is the ability to maintain quorum for your cluster.  If your replication provider does not support Disk Majority through replication, you will have to explore Node Majority with File Share Witness.  This will affect your design as a 3 node cluster with 1 node at the remote site and FSW at the production site would not have the ability to maintain quorum if the production site was lost. MS best practice for this would be to implement an even node cluster with 2 nodes at  each site and the FSW at a third site.   And there you have it.  While some considerations and research goes into implementing this solution, even a multi-subnet solution would be invaluable to organizations in the implementations of “warm” DR sites.

  • Different Apache log file for each subdomain?

    - by consolibyte
    Is it possible to configure Apache to use a different log file for each subdomain, even if all of the subdomains are within the same VirtualHost container? So, I have only one VirtualHost: <VirtualHost *:80> ServerName example.com ServerAlias test1.example.com test2.example.com test3.example.com </VirtualHost> And I want to end up with the following log files: /var/log/httpd-access_test1.log /var/log/httpd-access_test2.log /var/log/httpd-access_test3.log I know I can probably do this with a custom log format and split-logs, but I was wondering if there's a way to just have Apache do it for me.

  • To SYNC or not to SYNC – Part 4

    - by AshishRay
    This is Part 4 of a multi-part blog article where we are discussing various aspects of setting up Data Guard synchronous redo transport (SYNC). In Part 1 of this article, I debunked the myth that Data Guard SYNC is similar to a two-phase commit operation. In Part 2, I discussed the various ways that network latency may or may not impact a Data Guard SYNC configuration. In Part 3, I talked in details regarding why Data Guard SYNC is a good thing, and the distance implications you have to keep in mind. In this final article of the series, I will talk about how you can nicely complement Data Guard SYNC with the ability to failover in seconds. Wait - Did I Say “Seconds”? Did I just say that some customers do Data Guard failover in seconds? Yes, Virginia, there is a Santa Claus. Data Guard has an automatic failover capability, aptly called Fast-Start Failover. Initially available with Oracle Database 10g Release 2 for Data Guard SYNC transport mode (and enhanced in Oracle Database 11g to support Data Guard ASYNC transport mode), this capability, managed by Data Guard Broker, lets your Data Guard configuration automatically failover to a designated standby database. Yes, this means no human intervention is required to do the failover. This process is controlled by a low footprint Data Guard Broker client called Observer, which makes sure that the primary database and the designated standby database are behaving like good kids. If something bad were to happen to the primary database, the Observer, after a configurable threshold period, tells that standby, “Your time has come, you are the chosen one!” The standby dutifully follows the Observer directives by assuming the role of the new primary database. The DBA or the Sys Admin doesn’t need to be involved. And - in case you are following this discussion very closely, and are wondering … “Hmmm … what if the old primary is not really dead, but just network isolated from the Observer or the standby - won’t this lead to a split-brain situation?” The answer is No - It Doesn’t. With respect to why-it-doesn’t, I am sure there are some smart DBAs in the audience who can explain the technical reasons. Otherwise - that will be the material for a future blog post. So - this combination of SYNC and Fast-Start Failover is the nirvana of lights-out, integrated HA and DR, as practiced by some of our advanced customers. They have observed failover times (with no data loss) ranging from single-digit seconds to tens of seconds. With this, they support operations in industry verticals such as manufacturing, retail, telecom, Internet, etc. that have the most demanding availability requirements. One of our leading customers with massive cloud deployment initiatives tells us that they know about server failures only after Data Guard has automatically completed the failover process and the app is back up and running! Needless to mention, Data Guard Broker has the integration hooks for interfaces such as JDBC and OCI, or even for custom apps, to ensure the application gets automatically rerouted to the new primary database after the database level failover completes. Net Net? To sum up this multi-part blog article, Data Guard with SYNC redo transport mode, plus Fast-Start Failover, gives you the ideal triple-combo - that is, it gives you the assurance that for critical outages, you can failover your Oracle databases: very fast without human intervention, and without losing any data. In short, it takes the element of risk out of critical IT operations. It does require you to be more careful with your network and systems planning, but as far as HA is concerned, the benefits outweigh the investment costs. So, this is what we in the MAA Development Team believe in. What do you think? How has your deployment experience been? We look forward to hearing from you!

  • multiple godaddy domains to home router then reverse proxy to multiple internal servers [closed]

    - by Dan
    I need someone to steer me correctly... advising on all required components. I have multiple domains with godaddy, say site1.com , site2.com, site3.net I have multiple home LAMP servers... one on say, lampsrv1 = 192.168.0.2:8080 (windows) and lampsrv2 = 192.168.0.3:9080 (linux srv2) I would like to have server1.site1.com point to lampsrv1 and server2.site1.com point to lampsrv2 . I may also want server1.site2.com also point to my lampsrv1 as an option. My thinking is - I have a dedicated linux srv1 with a reverse proxy server behind the router, ie Apache or NGINX or equivalent directing to appropriate LAMP server. It's the godaddy subdomains, cnames or redirections, etc I'm having a challenge with for starters... I have tested apache with virtual servers but can't get proxying to work based on host header info... seems to go to one address making me think its actually the apache reverse proxying that's not quite working. Finally to add to this, my router has a dynamic IP but does lease for quite a while but that would be my final piece. So, I'm sure this might be a popular question but can't seem to piece this together. I need someone who has actually configured this scenario to advise but will take other suggestions.... please indicate if you have successfully configured this.

    Hi folks, is it better to have seperate country specific domains (which costs more money) or subdomains which define the country, for better SEO? eg. stackoverflow.com stackoverflow.com.au stackoverflow.co.uk vs stackoverflow.com au.stackoverflow.com uk.stackoverflow.com Assumption: int the search engine web master tools, each subdomain are associated to a country. eg. au.stackoverflow.com is associated to the country Australia. cheers! Update I understand that both methods do work, especially when i utilize the assumption, listed above. The question is about: Which method is better? Is there such a small SEO difference between them? Is the first method way way way better than the second with getting better SEO results? Update #2 A number of folks have suggested that the following is a good/better approach: stackoverflow.com/ stackoverflow.com/au stackoverflow.com/uk By adding a country specific iso code to the end of the url/the first folder of the domain can be recognised as the country. But a number of SEO mates have suggested that this is a valuable waste of folder level space. Er.. how can i explain. Ok, it's been suggested by some SEO experts that if the number of levels or folders in the domain exceeds 5 then the page drops dramatically in importance. Basically, you don't want to make it deep. As such, adding the country as the first level can be considered a waste, especially when it can be handled by the domain OR subdomain - hence the question :) So, any more thoughts on this? (Maybe SO is the wrong place to ask this question?)

  • Smart subdomain routing via reverse proxy

    - by Trevor Hartman
    I have two servers on my home network: OSX Server and an Ubuntu Server. I'd love to have external subdomains osx.mydomain.com point to osx and ubuntu.mydomain.com point to ubuntu. I know the normal way to do this is to have a static external IP address for each, but that's not an option as this is just my home setup. My question is: is there a way to do this with some reverse proxy trickery? OSX is currently the default entry point for all traffic. I was able to setup a reverse proxy on OSX for ubuntu.mydomain.com on port 80, so web traffic was correctly being proxied to my ubuntu. I'd like to ssh and do a bunch of other stuff though!

  • Issue tracking multiple domains with Google Analytics

    - by user359650
    I have 2 domains mydomain.com and mydomain.net which I'm trying to track with the same GA code. Here are the options I turned on: Subdomains of mydomain ON Examples: www.mydomain.com -and- apps.mydomain.com -and- store.mydomain.com Multiple top-level domains of mydomain ON Examples: mydomain.uk -and- mydomain.cn -and- mydomain.fr Which gave me the following code: _gaq.push(['_setAccount', 'UA-123456789-1']); _gaq.push(['_setDomainName', 'mydomain.com']); _gaq.push(['_setAllowLinker', true]); _gaq.push(['_trackPageview']); In this help page I read that _setDomainName must be changed for each domain which I did: -if you go to mydomain.net you get _gaq.push(['_setDomainName', 'mydomain.net']); -if you go to mydomain.com you get _gaq.push(['_setDomainName', 'mydomain.com']); When I generate traffic on both mydomain.dom and mydomain.net and watches GA push requests made with firebug I can see requests generated for both domains and the parameter called utmhn has the proper domain value (which matches that of _setDomainName and the browser address bar). However when I monitor the realtime statistics under Home->Real-Time->Overview I see pageviews for mydomain.net BUT NOT for mydomain.dom :( What am I missing to properly track both domains? PS: in the help page I mentioned they talk about setting up cross links which I didn't do for now as my understanding is that it shouldn't be needed to get what I'm trying to do to work. Also I want to mention that I do not have any tracking code for any of these 2 domains other than the one I mentioned.

  • Fake domain doesn't resolve when offline

    - by Fletcher Moore
    I have a flimsy grasp of DNS. Nonetheless, in order to install a local development copy of Wordpress MU, I needed to create a fake domain, which I called local.dev. It and all subdomains simply resolve to 127.0.0.1. Apache then directs to the correct folder. I installed PowerDNS, and got it working properly with a MySQL backend. I didn't feel comfortable, but since it worked, I didn't ask any more questions. The bizarre thing is it requires an internet connection to resolve correctly, and now I need to use it offline. If I am offline, Chrome provies the error: Error 105 (net::ERR_NAME_NOT_RESOLVED): The server could not be found. If you need more information, I am happy to provide it.

  • Two different domains as one user session in Google Analytics

    - by Mathew Foscarini
    I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.
