Server help?

So, when you maek a ServerSocket, it sets the ip address to your ip address, right? so... like 192.168.1.1 or something. But with this, you can only network with computers on the same network. My question is: how can you make a ServerSocket that is available to computers on other servers. A practical example would be, a Chat Server so you could chat with a freind at another house.

query involves Sockets, hence moving it to Sockets forum.

When you instantiate a ServerSocket, you can optionally specify the ip address the socket binds (listens) to. The system you are running on will need to be addressable/accessible to the machine(s) you wish to connect from. The 192.* you specify is a private address so your friends pc can access it if you are able to give him/her access to your private network.

Baring that option, you'll want to find a way to expose your server system to the internet with a "public" IP address. Depending on your system and configuration just having a public ip address may not be enough (i.e. if you are running a firewall that blocks access, you may have to work with your router settings, etc). Do some searches on things like 'expose pc to internet' to get you started.

You'll also want to do some research into your options and the potential risks of doing so as you'll potentially open up your machine to access from anyone on the WWW.

Look for the person at the party who can't shut up about their home network. Make friends with them. Have them set it all up for you - it's not too hard, and it would give them something more to talk about at their next party.
