Help with proxy on Ubuntu 11.10

[Avitar]

Hey everyone. I´m currently on campus here in my university and they restrict their network with a proxy. Ubuntu Software Center and the terminal somehow cannot use the system-wide proxy settings and cannot seem to download the files. Can anyone help me with this?

Thank you everyone for not helping <_< I´m sure if it was a girl you would´ve been jumping to her rescue. :angry:

Oh well, solution found [no thanks to you guys!!!]

Setting up apt-get to use a http-proxy

These are three methods of using apt-get with a http-proxy.

How to login a proxy user

If you need to login to the Proxy server this can be achieved in most cases by using the following layout in specifying the proxy address in http-proxy. (substitute your details for username, password, yourproxyaddress and proxyport)

http_proxy=http://username:password@yourproxyaddress:proxyport

Temporary proxy session

This is a temporary method that you can manually use each time you want to use apt-get through a http-proxy. This method is useful if you only want to temporarily use a http-proxy.

Enter this line in the terminal prior to using apt-get (substitute your details for yourproxyaddress and proxyport).

export http_proxy=http://yourproxyaddress:proxyport

APT configuration file method

This method uses the apt.conf file which is found in your /etc/apt/ directory. This method is useful if you only want apt-get (and not other applications) to use a http-proxy permanently.

On some installations there will be no apt-conf file set up. This procedure will either edit an existing apt-conf file or create a new apt-conf file.

gksudo gedit /etc/apt/apt.conf

Add this line to your /etc/apt/apt.conf file (substitute your details for yourproxyaddress and proxyport).

Acquire::http::Proxy "http://yourproxyaddress:proxyport";

Save the apt.conf file.

BASH rc method

This method adds a two lines to your .bashrc file in your $HOME directory. This method is useful if you would like apt-get and other applications for instance wget, to use a http-proxy.

gedit ~/.bashrc

Add these lines to the bottom of your ~/.bashrc file (substitute your details for yourproxyaddress and proxyport)

http_proxy=http://yourproxyaddress:proxyportexport http_proxy

Save the file. Close your terminal window and then open another terminal window or source the ~/.bashrc file:

source ~/.bashrc

Test your proxy with sudo apt-get update and whatever networking tool you desire. You can use firestarter or conky to see active connections.

If you make a mistake and go back to edit the file again, you can close the terminal and reopen it or you can source ~/.bashrc as shown above.

source ~/.bashrc

apt-get and ubuntu software center works now :)

Please note, anybody who ever reads this, that you need to do the four commands over everytime you reboot.
