Web Proxy

The compute nodes for the HPRC clusters do not have access to the internet. In order to allow internet access for compute nodes, you can enable web proxy when you run interactive or batch jobs on the compute nodes, by configuration environment variables, http_proxy and https_proxy or by loading the WebProxy module.

WebProxy module

For your convenience, a module has been provided to set the appropriate environment variables automatically.

module load WebProxy

This is the preferred method whenever it's applicable. Otherwise, proceed with the manual options below.

Set up environment variables

To enable web proxy, run these two lines before starting your interactive programs or add to your job script.

Terra

export http_proxy=10.76.5.24:8080
export https_proxy=10.76.5.24:8080

Grace

export http_proxy=10.73.132.63:8080
export https_proxy=10.73.132.63:8080

Set up proxy in the browser

You can enable web proxy for Firefox by following instruction and provide the IP/port for both HTTP and HTTPS proxies. For Terra, use 10.76.5.24 and port 8080. For Ada, use IP 10.72.2.7 and port 18080. For Grace, use IP 10.73.132.63 and port 8080.


Set up proxy in Jupyter Notebook Portal app

Run the following lines in your notebook:

Terra

import os
os.environ['http_proxy'] = '10.76.5.24:8080'
os.environ['https_proxy'] = '10.76.5.24:8080'

Grace

import os
os.environ['http_proxy'] = '10.73.132.63:8080'
os.environ['https_proxy'] = '10.73.132.63:8080'
