EDR Server: How to access the Carbon Black Yum repository through a proxy

Products

• Carbon Black EDR (formerly Cb Response)

Issue/Introduction

Allow communication to the Carbon Black Yum repository via proxy. 

Environment

• EDR Server: All Versions
• Intermediate proxy

Resolution

Update Yum's configuration to include a proxy parameter, and authentication parameters if applicable:

 

1. Edit the /etc/yum.conf file and include the proxy's URL

   • # The proxy server - proxy server:port number
     proxy=http(s)://myproxy.mydomain.com:1234

2. If applicable, include credentials for authentication:

   • # If the proxy requires authentication, provide the information below
     proxy_username=myuser
     proxy_password=mypass

3. Optional, if the proxy acts as a man in the middle, enforcing SSL may not be necessary.
   • Edit the /etc/yum.repos.d/CarbonBlack.repo file and change the sslverify option to zero:

     • sslverify=0

4. Ensure the repository URL is accessible with Yum's new proxy configuration:

   • yum info cb-enterprise
