Products

• Carbon Black EDR (formerly Cb Response)

Issue/Introduction

Unable to install cb-event-forwarder on CentOS 7 with libsasl2.0 package dependency errors

Environment

• Carbon Black Response Server: 6.2.4 and higher
• Carbon Black Event Forwarder: All Versions
• CentOS/RedHat 7

Cause

CentOS 7 has not been qualified with the CB-Event-Forwarder

Resolution

1. Stand up a CentOS 6 server
2. Install the CbOpenSource repository

   cd /etc/yum.repos.d
   curl -O https://opensource.carbonblack.com/release/x86_64/CbOpenSource.repo

3. Install the RPM via YUM:

   yum install cb-event-forwarder

4. On the CB Response Application Server, log in via SSH/Terminal and run the following command to get the user and password for RabbitMQ

   egrep 'RabbitMQUser|RabbitMQPassword' /etc/cb/cb.conf

5. On the cb-event-forwarder server, open /etc/cb/integrations/event-forwarder/cb-event-forwarder.conf
6. Edit the file with the correct information

   rabbit_mq_username=
   rabbit_mq_password=
   cb_server_hostname=

7. Port 5004 will need to be open for communication
8. Start the Cb-Event-Forwarder

   initctl start cb-event-forwarder
