you should try the following command in shell prompt

# export http_proxy=http://proxyServer-IP

ort/

then try

# wget http://site name

If any issue please check with DNS resolving. /etc/resolv.conf

for permanent you should add this (export http_proxy=http://proxyServer-IP

ort/ ) in /etc/rc.local or /etc/profile

/etc/profile i have edit it enter details
/etc/resolv.conf i update all local and global dns

but still commands like ping,traceroute,netstat,ssh outside world not working i want pass everything through proxy

Just check your firewall status.

# service iptables status

# iptables -L

You try onething ,

Goto system -> Preferences -> Nework proxy -> Manual Proxy configuration
and give the proxy server IP and port in HTTP Proxy section .

Try it then post the result . It may work as I've not tried ..
