If you need to force your Internet traffic through a proxy server, you can put your proxy server settings in
/etc/environment like this:
export http_proxy=http://server:port export https_proxy=https://server:port export ftp_proxy=https://server:port export no_proxy="localhost,127.0.0.1"
You may also need to include the actual IP address of the Security Onion box itself in the
no_proxy variable above.
If you’re going to run something using sudo, remember to use the
-i option to force it to process the environment variables. For example:
sudo -i rule-update
