Is it possible?
I know the answer may depend on what kind of work the server will be doing - game server, host server, mail server etc.
Does it always have to stay online, because it is by definition has become a server?
Yes you can, it's not that hard and as far as i know it has to be online all the time!

Ok lets say I want to create a connection between my iPhone app and my server (i'd like to try and use GoDaddy servers for this) to server real time location data to users.
I've seen plenty of good stuff online about using sockets, streams, ASIHttpmessage, CFHTTPMessageRef, etc., but what I'm unclear about is how to set up a server that continuously servers real time data to users (I believe you'd need a stream of data going to the user for this, not just a single http request and response). How does one take a host like GoDaddy and run server code on it. I know you can set up a server like this using terminal, but I don't have access to command line or the ability to run this "server program" from my web host as far as I know. Is there software I can download on my cpanel for this? Do I need a virtual private server and different hosting via GoDaddy maybe?
Does anyone know how I can do this or if my understanding of this whole thing is wrong. Please keep in mind I need this real time (or close to). Please, educate me. I really just need a better understanding of how this works.
I'm trying to get into an implementation of some kind of push notification for a Windows WPF client application and a java backed server.
The idea is to avoid as much as possible polling the server, so I thought to implement it with sockets and messages, and relying in some easy pulling solution in case a socket connection could not be done, (Firewalls, etc).
In the other hand is important that the data traveling get encrypted.
So I have a couple of question/"request for opinions" more related with the WPF client:
Perhaps already exist some solution for that, any tips?
Could be good to think in some SSL sockets connections for that?
If 2 is OK, there is some native solution for secure sockets in .net or any library?
If sockets solutions is an option, I guess i need to go through port 443 and by the way it will avoid many problems with firewalls and so on, am i right?
I know there is many question but all are related to the same problem.
Thanks in advance.

Yes, SSL is good if you need to keep the data secure during transfer
Yes, http://clientengine.codeplex.com/ indicates it supports SSL/TLS
Well, it depends on whether you are controlling the server or not. If you have control over it you can use whatever port you want.
We currently have POP3 mail accounts where I am and try as I might to convince my manager that we should be using hosted IMAP or Exchange he won't budge because of the cost. The staff are mostly out of office so there is no domain server here, however, we do have a dedicated server and I wondered whether I could use this to collect the mail and distribute it from there in some way.
Effectively what I'm trying to do is ensure mail is stored somewhere other than the end users machine because backups are user dependant at the moment. With hosted Exchange or Exchange on this server would be simple but my manager won't shell out for it. I have seen free mail servers called MailEnable and Axigen but unsure if they will do the job. Sorry if this seems like an easy or stupid question but never needed to do this before.
I am assuming due to the reference to Exchange that you are on Windows.
If you have an old box lying around that works, you could install linux on it and then choose from a number of different imap servers. Dovecot and Courier are both good choices and I have worked with them before.
You could use fetchmail to then pick up the mailboxes and then deliver to the imap boxes or get them deliver directly.
Setting up such a linux server for email was one of the first things I ever did on Linux. While initially daunting, once you get the hang of it, it is pretty straightforward and there are plenty of resources out there to help.
Ubuntu is probably the easiest to get used to. CentOs is also a reasonable choice.
You shouldn't be running your own server if you aren't willing to administer your own server, and they are not easy to configure if you don't know what you are doing (e.g., you mess up and you are exploited for spamming).
Look into a service like mailgun. In my application we are using them for forwarding to REST endpoints as well as onto another SMTP server.
Competitors that wound up not meeting my needs but may meet yours include Dyn, email yak, Sendgrid, etc. etc.
Why not just setup the mail clients to store their mail files on a standard network drive or share? I follow that this situation is pretty silly in your view - 100% because of the ridiculous constraints that you are being asked to work within: I would similarly find the solution I am suggesting ridiculous generally; but under the circumstances, it seems like a simple answer to your problem - replacing distributed mail storage and backup with centralized storage and backup.
Don't POP3 email clients have the option keep a copy on the server? Mine certainly does. See second tick box on the pic.
You can then periodically take a back up of all the emails from the server to stop it getting clogged up.
I'm interested in trying to make a connection from within my app to a proxy somewhere in the UK so I can listen to radio streams there that are blocked from the UK.
What would it take technically to implement this?
Is this even possible with the API available within iOS?
Many Thanks,

I think you need to use a VPN for this kind of thing. I have (of course) never done this myself but you could use OpenVPN in theory. I don't know how useful this is and there is a writeup here to explain why I say this. You need to jailbreak your phone.
I'm working on a personal project. It's to recreate server software for the game "Chu Chu Rocket" for the Sega Dreamcast. Its' servers went down in 2004 I believe. My approach is to use dnsmasq to change the originl hostname that the game originally connected to, to my own system. With a DC-PC server set up, I have done just that, now instead of it looking up a non-existent dns record, it connects to my computer which will eventually run the server software. I've used tshark (cli wireshark) to capture what's going on between the client (dreamcast) and the server (my computer). The problem is, I'm getting data, but I'm not sure how to interpret it, I don't know what it's saying, but I'm sure it can be done because private PSO servers were created, those are far more complex.
Very simply, where would I go about learning how to interpret data packets, and possibly creating packets that will respond to such queries from the client?
Thanks,

If you can get the source code for the server software on your PC, then that is the best place to look.
Otherwise, all you can do is look at the protocol, compare runs, and make notes of similarities and differences. With any luck, the protocol won't be encrypted.
