Centos 5,3 and yum

Hello Guys,
i got lately my host installed and configurated runing Vmware server 2.0.2
the only problem i have now is i am behind proxy so my yum is not working,
i did all the solution i can find in google
edite the etc/yum.conf file and /etc/profil
adding the proxy, export the proxy but nothing help
when i run yum update i get the next error and hope someone can help me with this

 

This looks like a problem with your DNS servers. Do you have valid DNS servers in /etc/resolv.conf?

 

yes i do have the correct one on the
/etc/resolv.conf
just check it,
thank you

 

Check config at interface eth0 (if you have eth0 interface).
If config is ok then type in console ifconfig & check interface.
Try ping to some website example: centos24.pl
More info in forum CentOS Linux

 

Hello Red Lady
thank you for the answer,
eth0 is ok all is ok i can ping my DNS but i can't ping outside the network,
i can browse to the internet, all seems ok
now Yum is working only if i am in The terminal,
when i connect with SSh ( putty) its gives me this,

 

What are the outputs of

Code:

env

in the terminal and in SSH?

 

this the SSH

terminal

 

In the terminal you have the following environment variable:

Code:

http_proxy=http://XXXXX:[email protected]:80/

which is not present in an SSH session.
What happens when you do

Code:

http_proxy=http://XXXXX:[email protected]:80/

in your SSH session? Does yum work then?

 

no its doesn't only on the terminal,
how can i add those into the SSH log file?

 

Can you run

Code:

export http_proxy=http://XXXXX:[email protected]:80/

? Does it work then?
