How To Authenticate Wifi Network For System?

[Ashfaqur Rahman]

Currently i am using a wifi network.
To access wifi authentication required. So when i open firefox it give me field for id and password.I have my id and pass. I access firefox using that and i can browse or download any thing.
But when I tried to download using terminal code:

sudo apt-get install

It says "Proxy authentication required" for every server.

Also I cant download the updates using wifi it gives following errors "Installation from unauthenticated source"

How can i authenticate with my id and password for terminal or system downloads?

You need to set the proxy setting of the current network in "proxy-settings"

[Ashfaqur Rahman]

I have set proxy settings from network option.I think there is no problem with proxy settings.The problem is Authentication.
if i give this code in the terminal

sudo apt-get update

It gives following error:

W: Failed to fetch http://download.opensuse.org/reposit...2.10/./Sources 407 Proxy Authentication Required

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dist...source/Sources 407 Proxy Authentication Required

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dist...-i386/Packages 407 Proxy Authentication Required

E: Some index files failed to download. They have been ignored, or old ones used instead.

Problem Is I dont know how to authenticate with my id and pass!!!

Check:

echo 'Acquire::http::proxy "false";' | sudo tee -a /etc/apt/apt.conf

Reboot and try again.

Check:

cat /etc/apt/apt.conf
cat /etc/apt/sources.list

[Ashfaqur Rahman]

I have tried all your ideas.I am telling u in details:

After connecting to wifi. From network settings I have set network proxy manual from automatic and gave my proxy settings there(IP = 172.16.180.251 and Port = 3128).
I also click the option "Apply system wide" too.
After that When I open a browser it asks me for my wifi username and pass.After giving my username and pass I can browse from browser also can download anything from browser.

But the problem is when I tried to download software through apt-get or try to update ubuntu, I CAN'T!

When I try to install through apt-get it gives following errors:

sajib@MULTIVAC:~$ sudo apt-get install  uget

Then I gave this code echo 'Acquire::http:roxy "false";' | sudo tee -a /etc/apt/apt.conf as you told before. And after that i found:

sajib@MULTIVAC:~$ echo 'Acquire::http::proxy "false";' | sudo tee -a /etc/apt/apt.conf
Acquire::http::proxy "false";
sajib@MULTIVAC:~$ sudo apt-get install  ugetReading package lists... Done

After that I examined cat /etc/apt/apt.conf which gives this:

sajib@MULTIVAC:~$ cat /etc/apt/apt.conf
Acquire::http::proxy "http://172.16.180.251:3128/";

Acquire::socks::proxy "socks://172.16.180.251:3128/";
Acquire::http::proxy "false";

And cat /etc/apt/sources.list which gives:

sajib@MULTIVAC:~$ cat /etc/apt/sources.list

AFTER THAT SAME PROBLEM STILL EXIST!!!!

[praseodym]

Did you run:

sudo apt-get update

[Ashfaqur Rahman]

I have run:

sudo apt-get update

It gives following errors:

Err http://extras.ubuntu.com quantal/main Sources                              
  407  Proxy Authentication Required
Err http://download.opensuse.org ./ Sources                                    
  407  Proxy Authentication Required

Its clearly seen that it cant authenticate.Thats what I am looking for.
How can I authenticate?
