Q. I'm behind a squid proxy server. How do I access internet via proxy server when I use wget, lynx and other utilities from a shell prompt?
A. Linux / UNIX has environment variable called http_proxy. It allows you to connect text based session / application via the proxy server. All you need is proxy server IP and port values. This variable is almost used by all utilities such as elinks, lynx, wget, curl and others.
Set http_proxy shell variable
Type the following command to set proxy server:
$ export http_proxy=http://server-ip:port/
$ export http_proxy=http://127.0.0.1:3128/
$ export http_proxy=http://proxy-server.mycorp.com:3128/
How do I setup proxy variable for all users?
To setup the proxy environment variable as a global variable, open /etc/profile file:
# vi /etc/profile
Add the following information:
export http_proxy=http://proxy-server.mycorp.com:3128/
Save and close the file.
How do I use password protected proxy server?
You can simply use wget as follows:
$ wget --proxy-user=USERNAME --proxy-password=PASSWORD http://path.to.domain.com/some.html
Lynx has following syntax:
$ lynx -pauth=USER:PASSWORD http://domain.com/path/html.file
Curl has following syntax:
$ curl --proxy-user user:password http://url.com/

For password protected proxies, I know it sometimes work directly included in http_proxy variable (ok it’s not so secure but it can make the work easier) :
$ export http_proxy=http://user:password@server-ip:port/
Great work. This worked for me. Thanks.
It is really correct?
export export http_proxy=http://proxy-server.mycorp.com:3128/
Slavko,
It was a typo. The faq has been updated.
Hi
I tried this, but still, I cannot ping google or any other site from within the shell.. it says ‘destination host unreachable’..
I’m using Redhat Enterprise 2.4..
Any idea what might be going wrong?
Thanks

export ftp_proxy=http://user:pasword@proxy-server.mycorp.com:port/
Is there support for excluding sites or a regex from using the proxy?
It seems that there is options for some commands, but is there a centralized option?
I.E. something like:
export no_http_proxy=*.ibm.com,10.0.0.0\24,…
