Proxy

Setup will ask if you want to connect through a proxy server and, if so, it will automatically configure the system for you.

If you have problems installing via your proxy server, you may want to consider the Airgap option as everything will install via the ISO image.

Configuration

If you need to make changes after Setup, please see the proxy settings in Administration –> Configuration –> manager.

Once there, select the proxy or no_proxy options.

General Information

There is no way to set a global proxy on Linux, but several tools will route their traffic through a proxy if the following lines are added to /etc/environment:

http_proxy=<proxy_url>
https_proxy=<proxy_url>
ftp_proxy=<proxy_url>
no_proxy="localhost, 127.0.0.1, <management_ip>, <hostname>"

Where:

<proxy_url> is the url of the proxy server. (For example, http://10.0.0.2:3128 or https://user:password@your.proxy.url)

<management_ip> is the IP address of the Security Onion box.

<hostname> is the hostname of the Security Onion box.

Note

You may also need to include the IP address and hostname of the manager in the no_proxy variable above if configuring the proxy on a forward node.

To configure Docker proxy settings, please see https://docs.docker.com/network/proxy/.

To configure git to use a proxy for all users, add the following to /etc/gitconfig:

[http]
  proxy = <proxy_url>

sudo

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 so-rule-update

Warning

Using sudo su - will ignore /etc/environment, instead use sudo su if you need to operate as root.
