With my box FC5 at work (Active Directory), I have been able to access the net , I have not logged in with my AD account , I logged in as username : root and password : forum,,,fake one (I know security implication, I have done this for test ).

First time when I tried to open a browser, window popped up asking me username and password for authentication to use internet (I entered my username: zillah and password:ad123 my active directory account,,,fake ), then I was able to browse the net.

When I tried to use the command below (via Terminal):

[root@local]#yum install yum (yumes),,,,It did not work, I believe because of the authentication (ISA proxy) that I mentioned above.

With the proxy , I followed the link below :

1- I added the line below to /etc/yum.conf
proxy=,,,,,,,,,,,,,,, because our ISA uses 8080 proxy
proxy_username=zillah,,,,,,,,,,,,,,,,,,,,,,,,,fake username
proxy_password=ad123,,,,,,,,,,,,,,,,,,,,,,,,,,fake password

Then I tried to use this :
[root]#yum update yum,,,,,,,,,,,,,,,,,,I received this error :

Loading "installation" Plugin
Settingup Update Process
Setting up repositories
Can not find a valid baseurl for repo:case
Error: Cannot find valid baseurl for repo:core

2- I removed the configuration above and I tried these:
http_proxy=" "
export http_proxy
yum update

[root@localhost # yum update yum

I usualy never touch the yum.conf file for proxy settings, I do the following to allow yum and any other program to access internet via proxy server.

Edit the following file


using your favorite editor (mine is now)

nano /etc/profile

and add to the end of the file

export http_proxy=http://password:password@
export ftp_proxy=$http_proxy

if you used nano and your done editing press CTRL-O to write the file , then press ENTER to confirm.
then press CTRL-X to exit.
then you logout from the system and log back in.

And I think it should work without any problems.
