Can someone provide me a direction or concept on how to set up a local web applications, for example, I currently use CUPS within Linux for printer setup and such. CUPS has a local web application by just changing the port number in the loopback address i.e.
127.0.0.1:631
And that takes you to the CUPS web interface. How is that set up? I'm sorry if this is a pretty easy question to answer, I just haven't really found a good answer yet.
You just need to install Apache on your Linux box. Once you do that, you should be able to go to http://127.0.0.1 and see your home page. The page is usually stored in /srv/www but it really depends on the Linux distro that you use.
By the way, CUPS does not use Apache, which means that they implemented a mini web server for their web interface.

I need the VPS services for hosting my ASP.NET project.
However, it's not just asp.net hosting, I also need SQL Server, RabbitMq and either my running conrole app or my windows service.
So I read the suggestions to use Amazon Web Services as they provide first year for free.
However when I registered I found that I don't have a clue of where I am:
I don't see the option of creating a virtual machine with Windows
I don't see the option of setting up SQL Server on such the machine
and so on.
So I was wondering whether I'm in the right place?
Please advise if AWS can provide me with what I need or I came to the wrong place?
AWS can provide all that you listed, but you'll need to do some learning on your end.
Basically you create an EC2 instance, and then use RDP to remote into it, and you can install software and configure it to your hearts content - just like it was any other physical server.
If you want to use SQL Server, you'll have the choice of installing it directly on the instance using your own license, or using their 'hosted' version of SQL Server call RDS. You'll need to read about it and decide which option is better for your project - there is no single right way.
Lastly, I will point out that although the 'free-tier' is nice, except for a really small application (i.e. small db on a low traffic website), you may find out the 'free-tier' does not quite give you all the power you need to run a busy application. I would not base your decision on wether or not you should use AWS on how much 'free' stuff you can get. The free-tier is nice for learning, but plan on spending some money for a truly robust solution.
I would like to know if this is even feasible. And if so, what a possible approach would be.
I am thinking that the .exe would have to be made available through a web service running on a windows stack (asp.net or php) and that a direct heroku solution would not be the way to go.
If you do it as a externally, yes. The main trick there would be making the service on the windows box and making sure your service was secure. If you're going for cloud stuff, your best bet is probably to set your service up on a windows server on EC2 or Rackspace or [insert cloud provider here]. They're not as cheap as linux boxes because of the license cost, but shouldn't be too difficult to manage.
Unless Heroku has changed a lot from the last time I looked at it, the underlying OS was linux of some variety, so it's really unlikely that you could get an windows binary to run internally without bundling wine into your application (probably not worth trying to figure out).
I'm a hobby programmer trying to build a client/server application suite, using Delphi XE.
I write stand-alone applications occasionally, for my personal use. The problem is I don't know ANYTHING when it comes to networking / multi-tier. I am willing to learn though.
I looked for ways to do this and DataSnap and IntraWeb jump out as the most likely candidates for the job. But, before I start using one or the other, I would like to know a few info I wasn't able to find on the web:
If I build an IW stand-alone app and deploy it on my site (as server) will I be able to connect to it/retrieve data with a client application? I need to do that within my Delphi written app, without using a browser and without using HTML (I know very little HTML and I'm not eager to learn). I know IntraWeb isn't meant for this, but will it work?
If I go with DataSnap and build a server app, will I be able to deploy it to my website? Or do I have to make a computer on the network the server?
In case anyone wants to know, I want to connect 5 computers(from different cities), to exchange information between them, if at all possible using ADO, as I'm very familiar with it.
Intraweb is a server based tool for building web sites, accessed via a browser. It is not "proper" multi-tier, and it sounds like it isn't what you need.
DataSnap is designed to do what you want I think. First, the ADO part would be on the server, and you would define an interface that the server offers to do tasks. Then your clients would call that interface over the internet to get data or do those tasks etc.
As for whether they will work on your web server, that depends on what your server is, and the access that is provided to it. A web server is just a PC, but typical hosting is fairly restricted to running "scripted" languages on that server, which reside in the hosting directory. A Delphi server would be a running executable (usually a Windows Service), listening on a port, and needs much more access to the computer than typical. You would need at least a virtual Windows server with administrator access to the desktop to allow it to work. In the first instance though, you could happily run the server on a DSL line or similar and make it work just fine. You can worry about hosting it on the net when you have customers paying for it.
So I have been looking every where, and so far i haven't been able to find anything that allows me to ssh from an iPhone app, and have finally resorted to posting a new pos.
So I am trying to make an app to manage servers and part of the tasks that I need to be able to do it to be able to some how remotely connect over the internet to a server with either an ip address or a DNS name.
The connection to the server does not necessarily need to be a SSH connection, it could be a telnet although because of the security issues i would prefer SSH (if it is a lot less code I would accept telnet), but on the other hand it could be some other type of connection.
The application just needs to be able to run a script on the server end and if a SSH or telnet I would not need any help but if some other type of connection i may need a bit of help. Also the server on the other end is intended to be linux server (either ubuntu or gentoo, but not sure which yet but all i can say is will almost certainly be a linux server operating system).
I have already looked at the libssh/2 and would welcome any other similar demos as have not been able to work out how get the frameworks to work as well as licensing issues with using the frameworks in it.
PS. I am relatively new to programming and although i have some basic knowledge of coding some type of tutorial or sample code would be greatly appreciated.
Many Thanks For Any Help

SSH is a hugely complicated beast. As long as you only need to execute one command without interactivity, it sounds like you could achieve the same thing by running a web server on the server and posting the commands via HTTP from the device. You can use SSL to achieve security. You'll need a mechanism that allows you to authenticate the device (you'd need something with ssh, too). And you'll have to have something in the web server on the server that figures out and runs the desired script. But all that is still hugely easier than dealing with libssh.
I really have no idea how to ask this, so with that have no idea where to search either. So.. I have a unique situation I think.
I have virtual box installed, with a local running server on it. I access it through my windows machine the host machine rather. via 127.0.0.1:3001. So I am here developing an app that can only be hosted on the virtual machine, as there are a lot of moving parts specific to it that can't be hosted on a WAMP or even a typical web-server elsewhere. The vm OS is Ubuntu. So here I am with a slight issue I want to see how this looks on my iPad, and a couple other tablets as the software being built into the VM is browser based as far as the GUI goes.
So theres the pretense. Heres the delima I want to use the built in browser on ipad to navigate to the browser based portion of my app on the VM like I can do through the Host machine. But Im not entirely sure how to achieve that. Its gotta be done over Wifi but what would I need to do to set that up accordingly?
Host Machine is Windows 7 Ultimate, VM is Ubuntu 10.x. This is not a screen sharing notion either. I don't want a to remote view the PC I want to type in the equivilant of 127.0.0.1:3001 into my ipad browser and view the service like I do vm to host machine.
Change network virtual card on virtual machine parameters. You should select 'bridget' card insteat NAT or Host only. In this way virtual machine get a network IP and you can connect to this IP from your IPAD.
