BU Web Proxy

Commonly the proxy is set using service specific environmental variables. Here are examples for BU.

/etc/environment

Environment variables can be set system-wide, regardless of the shell used, via /etc/environment. The /etc/environment file is read by pam_env.so during login, so only works with PAM logins. It doesn’t use export or support expanding existing variables, so setting PATH=$PATH:/something will result in the literal string “$PATH” appearing in your PATH.

http_proxy="http://webproxy.bu.edu:8900"
https_proxy="http://webproxy.bu.edu:8900"
ftp_proxy="http://webproxy.bu.edu:8900"
rsync_proxy="http://webproxy.bu.edu:8900"
no_proxy="localhost,127.0.0.1,.bu.edu,.ad.bu.edu,128.197.,10."

Bash Environment

export http_proxy="http://webproxy.bu.edu:8900"
export https_proxy="http://webproxy.bu.edu:8900"
export ftp_proxy="http://webproxy.bu.edu:8900"
export rsync_proxy=$http_proxy
export no_proxy="localhost,127.0.0.1,.bu.edu,.ad.bu.edu,128.197.,10."

Or all in one line:

export {http,https,ftp,rsync}_proxy="http://webproxy.bu.edu:8900"
export no_proxy="localhost,127.0.0.1,.bu.edu,.ad.bu.edu,128.197.,10."

There’s also:

export dns_proxy=$http_proxy

but don’t use it.

You can place these in .bashrc, .profile, /etc/profile, /etc/profile.d/proxy.sh, or whatever fits.

wget

Edit ~/.wgetrc file for personal settings or /etc/wgetrc for system wide settings:

use_proxy=yes
http_proxy=webproxy.bu.edu:8900
https_proxy=webproxy.bu.edu:8900
ftp_proxy=webproxy.bu.edu:8900

or via -e options placed after the URL:

wget ... -e use_proxy=yes -e http_proxy=webproxy.bu.edu:8900 ...

cURL

From the command line:

curl -x http://webproxy.bu.edu:8900 -L http://url

yum

You may want to add this line to /etc/yum.conf:

proxy=http://webproxy.bu.edu:8900

apt

You may want to add this line to /etc/apt/apt.conf.d/proxy.conf:

Acquire {
  HTTP::proxy "http://webproxy.bu.edu:8900";
  HTTPS::proxy "http://webproxy.bu.edu:8900";
}

Windows Server 2012/2016

There are 2 proxy setting for Windows. One for the browswer and one for the OS. You can set the proxy for the OS directly with

netsh winhttp set proxy webproxy.bu.edu:8900

or steal it from the browser’s Web Settings:

netsh winhttp import proxy source=ie

You can also bypass the proxy for local sites:

netsh winhttp set proxy proxy-server="webproxy.bu.edu:8900" bypass-list="*.ad.bu.edu;*.bu.edu;localhost"

Also useful:

netsh winhttp reset proxy
netsh winhttp show proxy
