Testing with a single PC

I have almost completed coding and have access to just a single PC and am wondering how I can go about testing my local and remote mode using the hardware I have. Any suggestions would be appreciated. If a second PC is absolutely essential to test then I can get one.
Could anyone in a similar situation tell me how they went aboutthe testing phase
Please your comments.
Thanks

I do not have 2 PCs, but I asked a friend of mine who runs
a linux server to set up an account for me. I ftp'd my
server code to the linux server, and got the server running.
I then ran the client on my home PC against this server.
It seemed to work rather well. So I suggest getting a friend
who has a non-firewalled Internet feed (cable seems to work)
to run your server.

Thanks shall try it out
