Configure proxy

If your FreeBSD box works behind a proxy, you may need to configure proxy to make it access network.

For csh or tcsh, set proxy in /etc/csh.cshrc: 

  1. setenv HTTP_PROXY http://web-proxy.xxxxxx.com:8080
  2. setenv HTTPS_PROXY https://web-proxy.xxxxxx.com:8080

For sh, set proxy in /etc/profile: 

  1. export HTTP_PROXY http://web-proxy.xxxxxx.com:8080
  2. export HTTPS_PROXY https://web-proxy.xxxxxx.com:8080
