I'm in a lab and have to use proxy for Internet access. I can set proxy on firefor/chrome (8080) and use the proxy to access Internet. But when I set the proxy on system setting of ubuntu(http://www.ubuntugeek.com/how-to-configure-ubuntu-desktop-to-use-your-proxy-server.html), it doesn't work. WHy?
I tried export http_proxy=[the proxy ip]:8080 on terminal, trying to connect Internet via my terminal, but it doesnt work.
