Everything Proxy

More often than not I find myself behind a proxy server. And then, that one tool I need, just doesn't work. Well, this guide might help.

APT (Debian's Advanced Package Tool)

# Configure the proxy in the proxy.conf file
cat /etc/apt/apt.conf.d/proxy.conf
Acquire::http::Proxy "http://proxy.domain.com:8080";

Burp Suite

Configure an upstream proxy server:

1. Select tab "User options".
2. Select sub-tab "Connections".
3. Under "Upstream Proxy Servers" add/enable the upstream proxy server to use. Example:
   • Destination host: *
   • Proxy host: proxy.domain.com
   • Proxy port: 8080
   • Authentication type: None
4. Click OK

curl

# Set the proxy
export HTTP_PROXY=http://proxy.domain.com:8080
export HTTPS_PROXY=http://proxy.domain.com:8080
export ALL_PROXY=http://proxy.domain.com:8080

Firefox

1. Select menu Preferences > Network Settings > Settings...
2. Select on of the following:
   • Auto-detect proxy settings for this network
   • Use system proxy settings
   • Manual proxy configuration

Git

# Set the proxy
git config --global http.proxy http://proxy.domain.com:8080

# Check the proxy value
git config --global --get http.proxy

# Unset the proxy
git config --global --unset http.proxy

Homebrew

# Set the proxy
export HTTP_PROXY=http://proxy.domain.com:8080
export HTTPS_PROXY=http://proxy.domain.com:8080
export ALL_PROXY=http://proxy.domain.com:8080

Hydra

Different types of proxies are possible:

export HYDRA_PROXY=connect://proxy.domain.com:8080
export HYDRA_PROXY=socks4://proxy.domain.com:8080
export HYDRA_PROXY=socks5://proxy.domain.com:8080

OpenVPN

Edit the configuration (.opvn file) and add the proxy information. Some examples:

# Simple HTTP proxy
http-proxy proxy.domain.com 8080

# HTTP proxy with Basic authentication
http-proxy proxy.domain.com 8080 stdin basic

# HTTP proxy with NTLM authentication
http-proxy proxy.domain.com 8080 stdin ntlm

pip (Python's package management)

export HTTP_PROXY=http://proxy.domain.com:8080
export HTTPS_PROXY=http://proxy.domain.com:8080

wget

export http_proxy=http://username:password@proxy.domain.com:8080
export https_proxy=http://username:password@proxy.domain.com:8080
export ftp_proxy=http://username:password@proxy.domain.com:8080

# No proxy for these
export no_proxy="domain1.com,domain2.com,domain3.com"
