Carbon Black EDR (formerly Cb Response)

Issue/Introduction

  • After install a Unified EDR Server the cb-nginx service does not start
  • The following error message is seen in the /var/log/cb/nginx/startup.log
    nginx: [emerg] invalid number of arguments in "resolver" directive in /var/cb/nginx/props/nginx.runtime.resolver.prop
               

Environment

  • EDR Server: 7.7
  • EDR Server Unified View:7.7

Cause

  • When the Unified View Server starts it attempts to read the nameserver line from the /etc/resolv.conf
  • If the /etc/resolve.conf file does not have a nameserver line then the cb-nginx process does not start as expected 

Resolution

 A workaround to this issue is to add the following line to the /etc/resolv.conf 
nameserver localhost
