Many enterprise environments require a proxy to be set before outbound web communications is allowed. The Velociraptor client uses HTTP to communicate with the server, and therefore must use a proxy to connect in such environments.
It is possible to specify the HTTP proxy using the configuration file or environment variables.
Environment variables may be configured using group policy or similar
methods. Setting the http_proxy and https_proxy environment
variables will force the client to go through the specified proxy.
The rules for environment variables are described here:
// ProxyFromEnvironment returns the URL of the proxy to use for a
// given request, as indicated by the environment variables
// HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions
// thereof). HTTPS_PROXY takes precedence over HTTP_PROXY for https
// requests.
//
// The environment values may be either a complete URL or a
// "host[:port]", in which case the "http" scheme is assumed.
// The schemes "http", "https", and "socks5" are supported.
// An error is returned if the value is a different form.
You can also hard code the proxy in the configuration file’s Client section:
Client:
proxy: http://proxy.example.com:3128/
server_urls:
- https://velo.example.com:8100/
