Getting around a Proxy server?

[sandso'time]

My LAN uses a proxy for access control to the web. I suppose this is preventing me from being able to connect to any host servers to update the repository. Is there a way to get around this?

You can use command as:

export http_proxy=http://username: password@proxy_url: port_number

It should work (note: no space). Good luck!
