I'm evelauting using thie service. http://www.freegeoip.net/ & i quote the text below.
The freegeoip web server is free and open source so if the public service limit is a problem for you, download it and run your own instance
The public service limit of 10,000 queries per hour by default might or might not be a problem for me, so i just want to take the safe route early enough by downloading it and running my own instance.
However, i have zero experience on deploying such a server. Does any one here have or know of a walk-through that can get me started deploying my won instance. Can i host this server on windows or my own instance must be hosted on a linux server?
My site is hosted in IIS on windows.

This question is purposefully general because I'm trying to understand things more from an architectural perspective, because that will impact which group I need to contact. My team is using Azure DevOps (cloud) with on-prem build agents. The agents connect to ADO via a proxy.
We use several tools in-house provided by vendors with ADO plugins in the Marketplace that require us to set up service connections. Because the services are installed on-prem, the endpoints we enter are not available via the Web (e.g. https://vendor-product.my-company.com).
If I log into the build machine and open up IE, I am able to connect to the service endpoint URL. However, whenever I try to run a task from ADO, it fails with some kind of connection-related issue ("The underlying connection was closed: An unexpected error occurred on a send", "Task ended with an exception: Error: read ECONNRESET", etc.).
The way I thought it worked, all the work takes place on the build machine itself, so the calls would be going from my-build-server.my-company.com to https://vendor-product.my-company.com. Those error messages though make me wonder if the connection is actually coming from https://dev.azure.com.
So the questions I have are:
For situations like this, is the connection to a service endpoint going to be seen as coming from my on-prem build agent, or from ADO (or does it vary based on how the vendor writes their plugin)?
If the answer to #1 is "it varies", is there any way for me to tell just from the plugin itself without having to contact the vendor? (In my experience some of the vendor reps don't understand how the cloud works.)
and/or
Because my build agent was configured to use a proxy when I set it up, is it going to use that proxy for all connections, even internal ones? I think I can set up a proxy bypass list for the agents but I presently only have read access to the build box. I can request temporary elevated access but I'd need some level of confidence that's what the issue is.
Hope I explained the situation clearly, thanks in advance for any insight.
I have 3 tier architecture server which are 1 Web Front Ender Server (WFE), 1 Application Server (APP) and 1 Database Server (DB) that installed in 1 physical server / host. Then suddenly the host broken caused by the RAM is broken.
After that happen, we done some recovery and use the VM backup then restore it to the new host / physical server. After we restored all the Virtual Machine (WFE, APP, DB) the sharepoint running OK and then when we try to retract and deploy some solutions, the deployment status stucks at deploying and retracting whenever we tried.
We have tried to deploy and retract from Central Administration, using powershell command, and using stsadm command line but keeps getting the same result. Anyone having the same problem ? and how you solve this ?
After I tried many things to fix the problem.
Finally I fixed the problem. All I did,
1.Checking the Sharepoint Timer Service running on every Sharepoint Server in farm
2.Restarting the Sharepoint Timer Service (you can check the service in windows services.msc) on every Sharepoint Server (Web Front End Server and Application Server) in the farm at the same time
Thank you guys
I've read some articles recently on setting up AWS infrastructure w/o enabling SSH on Ec2 instances. My web app requires a binary to run. So how can I deploy my application to an ec2 instance w/o using ssh?
This was the article in question.
http://wblinks.com/notes/aws-tips-i-wish-id-known-before-i-started/
Although doable, like the article says, it requires to think about servers as ephemeral servers. A good example of this is web services that scale up and down depending on demand. If something goes wrong with one of the servers you can just terminate your server and spin up another one.
Generally, you can accomplish this using a pull model. For example at bootup pull your code from a git/mecurial repository and then execute scripts to setup your instance. The script will setup all the monitoring required to determine whether your server and application are up and running appropriately. You would still need an SSH client for this if you want to pull your code using ssh. (Although you could also do it through HTTPS)
You can also use configuration management tools that don't use ssh at all like Puppet or Chef. Essentially your node/server will pull all your application and server configuration from the Puppet master or the Chef server. The Puppet agent or Chef client would then perform all the configuration/deployment/monitoring changes for your application to run.
If you with this model I think one of the most critical components is monitoring. You need to know at all times if there's something wrong with one of your server and in the event something goes wrong discard the server and spin up a new one. (Even better if this whole process is automated)
Hope this helps.
It seems I am running into the Microsoft Distributed Transaction Coordinator (MSDTC) related issue.
SCENARIO
I am using TransactionScope and with in the single scope it hits two different databases on different servers (for instance, DB_A running Windows Server 2003 and DB_B running Windows Server 2008). One database is accessed using Entity Framework 4.0 and another using normal ADO.NET APIs.
When I run the application from my development machine (running WinXP) it commits and rollbacks both the connections accurately. But when I run the application, deployed on another server (for instance WAS_A running Windows Server 2003) it commits correctly but in case of exception is doesn't roll back the database activities on both the servers.
I thought it would be the MSDTC configuration issue on the WAS_A. So I went to the MSDTC -> Security Configuration and checked all the available options (as I did previously on other machines). But still I am facing the same issue.
Looking for your expert advices. :)
I believe that you need to look into Enabling Transaction Flow. Specifically, take a look at how one may error and the other complete as described in TransactionScope and WCF Services:
an error in a second WCF service call was NOT rolling back the changes made in a previous WCF service call...
In order to create an ambient transaction in your client and ensure that it is used by your WCF services...
The article then details the following steps:
Configure Your Binding with transactionFlow
Decorate Your Interface with [TransactionFlow(TransactionFlowOption)]
Decorate Your Method with [OperationBehavior(TransactionScopeRequired)]
Optionally update your Connection Strings with Transaction Binding*
*Note: This is optional in my opinion.
I've deployed in Windows Azure a website made with Umbraco, using
Windows Azure Accelerator for Umbraco.
For development and test i used a test Hostname. Now it's time to switch to the official DNS hostname..
How can I change current hostname?
Actually i configured hostname at deployment time (the only way i know to do this) but i can't deploy again, since many files have been changed working on website on Azure.
EDIT
Let me explain: at the step prompt in the image (during web site deploying) I used as Domain Name "test.mywebsite.com", and configured real DNS.
Now the website is configured, so I'd like to make mywebsite.com point to that site;
But is'nt enough if i configure mywebsite DNS! Shall I deploy again? An will I lose any of the changes I made?
I'd like to make two comments on your question:
1) In order to host your Azure application under a custom host name, you will need to sign up with a DNS provider that supports C-NAME records (most do). I suggest someone like GoDaddy.com because by default C-NAME records can only resolve your "www.domainname.com" records and cannot do anything for queries where "www." is dropped from the URL. DNS providers like GoDaddy also have an option to redirect all traffic destined for "domainname.com" to a URL of your choice. This is a huge deal for Azure apps. Frankly speaking, it is somewhat disappointing that for all the PaaS and IaaS features of Azure, DNS was not included in the overall package.
2) I am a little worried when you say that you can no longer redeploy your app due to the changes made. Can you elaborate on that? Have you made changes to the application's code running on VM's in Azure without going through redeployment process? If so, this is a huge no-no. Your VM's running in Azure are not "permanent". Microsoft and your redeployment process can (and will) re-stage those VM's to the original package at any given time. Microsoft will re-image your VM's at least once a month during their monthly OS upgrades. But they can also do so when they need to move your VM to another rack, etc. Whatever changes that you make to your app must be either stored in source-control before deployment or in a permanent storage facility like SQL Azure, Azure Storage, etc.
HTH
Finally i think that the answers to my questions are:
-Shall I deploy again? Yes, i must deploy again
-Will I lose any of the changes I made? Many changes will be mantained since are stored into DB. But I have to do many activities to make new website work!
This answer confirms my theory:
In my case, I created and uploaded a site with a name, let's say
http://www.contoso.com and then paid a domain from a registrar let's say
http://www.example.com, when I mapped
http://MyAcceleratorsService.cloudapp.net/ to my new domain
( http://www.example.com ) and tried to open that domain I got the home page of
the Accelerator and not the uploaded site.
I had to upload the site again to Azure (using UploadUmbracoSite.cmd
from Accelerator application) and when uploading enter the same domain
name as the one I registered: http://www.example.com. Then, I was able to
browse my uploaded site as expected.
As for your question, will upload site again using
UploadUmbracoSite.cmd (is in the Setup folder) and will enter the new
domain name when requested.
Exactly what I was trying to avoid.. but the only solution, i suppose.
Well it was not easy to publish again, i got errors of many type (i suppose tied to some components that i've installed after deploy and that are not installed in new deployed website).. i'm going to solve them.
Edit
Completed my work:
- loads of different attempts, no-one worked
- CTP backup of DB
- deleted DB and website
- new full deploy of umbraco
- CTP restore of DB
finally:
-all work on content is OK
-all work on styles, pages, templates is lost
Changing hostname is hard; dont'use test hostname but definitive hostname from the beginning.
If anyone has suggest, i'll be pleased to test it, anyway
This is not really an answer to your question, but it might be a solution to your problem: Use a CNAME record to make the production DNS name point to your development name. E.g. www.productionname.com will the point to www.testname.com. I am not sure if everything will just work out of the box, but it seems to be worth a try.
This requires, that your hosting provider allows you to set up CNAME records.
