Proxy Settings for most tools

10 April 2016

During software development, we come across so many tools, editors and frameworks which have their own way to configure HTTP/HTTPS Proxy especially when using it from your Work environment. Many times, these settings will not work while at home since the proxy is not available. This blog is aimed to capture the settings for most tools for Linux/OSX in one single place from my cheat sheets.

Linux/OSX

Most tools will usually work by simply setting the environment variables. They are http_proxy and https_proxy.

I usually set aliases in my .profile or .bash_profile.

alias proxy='export http_proxy=http://www.example.com:80; export https_proxy=http://www.example.com:80'
alias noproxy='unset http_proxy; unset https_proxy'

Then depending on which network I am connected too, I simply run proxy or noproxy.

Git

Enable proxy

git config --global http.proxy http://www.example.com:80
git config --global https.proxy http://www.example.com:80

Disable proxy

git config --global --unset http.proxy
git config --global --unset https.proxy

Verify your current settings
```
git config --global --list
```

NPM

Enable proxy

npm config set proxy http://www.example.com:80
npm config set https-proxy http://www.example.com:80
npm config set strict-ssl false

Disable proxy

npm config delete proxy
npm config delete http-proxy

Verify your current settings
```
npm config list
```

Maven

Enable Proxy

To figure out which maven settings file is being used, run mvn -X in your project and look at the first few lines. Configure the settings.xml file as follows:
```
<proxies>
  <proxy>
    <id>proxy</id>
    <active>true</active>
    <protocol>http</protocol>
    <username>proxyuser</</username>
    <password>proxypass</password>
    <host>example.com/host>
    <port>80</port>
    <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
  </proxy>
</proxies>
```
If you set active above as true, proxy is always enabled. If you want to choose proxy at runtime, set active to false. Then while running the maven command, choose mvn <goals> -Pproxy
Disable Proxy

Set active as false or comment out the section above.

Gradle

Enable Proxy

You can add a gradle.properties to your current project directory or to your <home>/.gradle/gradle.properties. Add the following lines:

systemProp.http.proxyHost=www.example.com
systemProp.http.proxyPort=80
systemProp.https.proxyHost=www.example.com
systemProp.https.proxyPort=80

Disable proxy

Remove the above settings or comment them.

Docker

Enable proxy.

Edit /etc/default/docker, add two lines:

export http_proxy="http://server:port"
export https_proxy="http://server:port"

SVN

Enable proxy. Add the following to ~/.subversion/servers.

[global]
http-proxy-host = www.example.com
http-proxy-port = 80

APT-GET

Enable proxy. Edit /etc/apt/apt.conf. Add

Acquire::http::proxy "http://www.example.com:80";
Acquire::https::proxy "http://www.example.com:80";

wget

wget will pick up the environment variables http_proxy and https_proxy. However if these environment variables are set, the proxy will always be used. To use wget without proxy, use:

wget --no-proxy http://...

Brackets

Open Preferences, add the following to brackets.json
```
"proxy": "http://www.example.com:80"
```

yum

Open /etc/yum.conf ( sudo vi /etc/yum.conf)

Add line: proxy=http://www.example.com:80

rpm

$ sudo rpm -ivh –httpproxy my.proxy.com –httpport 8000 http://pkgs.repoforge.org

Till then…
