KarthikRamanan: Fixed issue with white spaces for no_proxy

This page lists some configuration tips for working behind a proxy.

== HTTP/HTTPS/FTP Setup ==

Set the following environment variables in your ~/.bashrc file. This example uses the same proxy server and port number for all three protocols.

export http_proxy='http://myproxy.example.com:1080/'
export https_proxy='https://myproxy.example.com:1080/'
export ftp_proxy='http://myproxy.example.com:1080/'
export no_proxy='.example.com'

== Git Setup (with socat)==

First make sure you have the socat utility installed on your host (in Ubuntu, this should be a simple command "sudo apt-get install socat")

Create a script named ''git-proxy'' and put it in /usr/local/bin:

#!/bin/bash
# $1 = hostname, $2 = port
PROXY=myproxy.example.com
exec socat STDIO SOCKS4:$PROXY:$1:$2
Then run the following command:

git config --global core.gitProxy git-proxy

== Git Setup (with nc)==

First make sure you have the netcat utility (nc) installed on your host.

Create a script named ''git-proxy'' and put it in /usr/local/bin:

#!/bin/bash

PROXY=myproxy.example.com
PORT=1080

case $1 in
# list internal git servers here that you do not want to use
# the proxy with, separated by a pipe character '|' as below:
internalgit1.example.com|internalgit2.example.com)
METHOD="-X connect"
;;
*)
METHOD="-X 5 -x ${PROXY}:${PORT}"
;;
esac

/usr/bin/nc $METHOD $*

Note that on some Linux distros, the nc binary is in /bin. You can also change the '5' in the second METHOD line to '4' if your proxy server only supports SOCKS v4.

Then set the environment variable GIT_PROXY_COMMAND in your ~/.bashrc file and point it to this script:

export GIT_PROXY_COMMAND=/usr/local/bin/git-proxy
export GIT_PROXY_IGNORE="example.com"

== Subversion Setup ==

You'll need to have the following in your ~/.subversion/servers file:

[global]
http-proxy-exceptions = *.exception.com, www.internal-site.org
http-proxy-host = myproxy.example.com
http-proxy-port = 1080

You can also set ''http-proxy-username'' and ''http-proxy-password'' if your proxy requires authentication.

== CVS Setup (this seems useless since we don't have any recipe requiring cvs now) ==

For CVS checkouts to work correctly, you need to add some options in your Poky ''local.conf'' file.

CVS_PROXY_HOST = "myproxy.example.com"
CVS_PROXY_PORT = "1080"
