Linux Dedicated Server Hosting

Sony PS3 Running Linux Server?
Was wondering coz i know ps3 you can run a seperate OS i've made a choice of goin for Helios/yellow dog. Usually with my pc for example if i were to run any game and make a server i have to do some port forwarding in order for people to connect to me and stuff coz i'm behind a router. But when i play warhawk on my ps3 i make a server dedicated or non dedicated i dont need any port forwarding or DMZ. Was wondering if i install another OS on my PS3 and decide to run a server will it work the same? will i need to forward any ports for people to connect to me like when my pc hosts any kinda server or can it just do it on its own? And will my public IP address be the MacID or my normal ISP ip address?

You will need to port forward or at least open incoming ports on the firewall to allow people to connect. Your public address will be the same as before, it's attached to the router.

Running a Server from Home - How do you do this?
We work on some projects, scripts, which needs sometime dedicated server to host to run. As dedicated servers are just an extra cost for us, as we do need this hosting for just testing purpose for 10 to 20 days for script. So i am thinking to run own webserver for this job from my home. Can anyone tell me what is needed for this type of task, and is it feasible... have you done this before, if so what have been your experiences? Note: I have extra desktop pc. with DSL internet Connection with unlimited bandwidth.... --- I want to run Unix/Linux, with Apache.... but I am not much sure, how to link our domain name with this server.... Hope you can answer the question asap Thanks in advance.

quite difficult best job for me was ms server 2003 which has user-friendly wizard which helps u quite a lot try it worked for me i even had a wicked media server set up playing non stop movies , kinda made it like a tv channel
