how can i stream live video to my web page, i want to put a camera on 1 of my web pages ,for a small private family site hosted on a linux server connected to my adsl2 connection

What you need is a streaming media server runnning from your computer. Since you have ADSL it should work well for you. I recommend searching for one at either http://www.freewarefiles.com or http://www.download.com My site below under Server Talk has a section to explain the basics of setting up your own server. Hope this helps
