Configuring a Global Proxy

You configure global HTTP and HTTPS proxies in the /etc/profile.d/ directory of Cumulus Linux. To do so, set the http_proxy and https_proxy variables, which tells the switch the address of the proxy server to use to fetch URLs on the command line. This is useful for programs such as apt/apt-get, curl and wget, which can all use this proxy.

  1. In a terminal, create a new file in the /etc/profile.d/ directory. In the code example below, the file is called proxy.sh, and is created using the text editor nano.

    cumulus@switch:~$ sudo nano /etc/profile.d/proxy.sh
  2. Add a line to the file to configure either an HTTP or an HTTPS proxy, or both:

    • HTTP proxy:

      export http_proxy
    • HTTPS proxy:

      export https_proxy
  3. Create a file in the /etc/apt/apt.conf.d directory and add the following lines to the file for acquiring the HTTP and HTTPS proxies; the example below uses http_proxy as the file name:

    cumulus@switch:~$ sudo nano /etc/apt/apt.conf.d/http_proxy
    Acquire::http::Proxy "http://myproxy.domain.com:8080";
    Acquire::https::Proxy "https://myproxy.domain.com:8080";
  4. Add the proxy addresses to /etc/wgetrc; you may have to uncomment the http_proxy and https_proxy lines:

    cumulus@switch:~$ sudo nano /etc/wgetrc
    https_proxy = https://myproxy.domain.com:8080
    http_proxy = http://myproxy.domain.com:8080
  5. Run the source command, to execute the file in the current environment:

    cumulus@switch:~$ source /etc/profile.d/proxy.sh

The proxy is now configured. The echo command can be used to confirm aproxy is set up correctly:

  • HTTP proxy:

    cumulus@switch:~$ echo $http_proxy
  • HTTPS proxy:

    cumulus@switch:~$ echo $https_proxy
