I have installed the Simulator in Ubuntu.
When I try to access the simulator, I am getting the message as "We cannot establish an HTTP connection which is required to update Widgets, please check your network and proxy settings. You can bypass this network check entering YES at the prompt or simply hit ENTER to exit View"

Is there a possibililty to access the proxy without any user authentication,if yes, can any one help me with the technique

Is there any way where I can specify the UserName and Password with the Proxy.
I have tried this one
$export http_proxy=http://<user>:<password>@<proxy-server-ip>:<port>
, but it didnot work

The usual Syntax is as follows
# To use a web proxy please add the proxy address below
# example: proxy=myproxy.mydomain.com:8080
proxy=



Please help me
