NetWitness Precheck - YUM Proxy Check Error for Node0 Admin Servers Only

Issue

The Precheck tool fails with the below error message:

NetWitness Precheck - YUM Proxy Check Error for Node0 Admin Servers Only

This probe checks for the existence of ‘ yum.conf’ file and presence of proxy within the file.

Cause

The system upgrade fails if proxy is present and enabled in ‘/etc/yum.conf’.

.

To ensure that upgrades and installations proceed smoothly, it is necessary to remove any proxy settings beforehand. This is because the process relies on receiving accurate responses to multiple API calls, which can misfire if a proxy is set up. After the upgrade or installation is complete, custom proxy settings can be re-added.

Resolution

Navigate to ‘/etc/yum.conf’ file and remove the proxy information. Follow these steps to remove the proxy information:

1. vi /etc/yum.conf Get into insert mode (press i)

2. Remove the following lines:

 proxy= <porxy_URL>
 
proxy_username=<proxy_username>
 
proxy_password=<proxy_password>

3. Save the changes.

4. After saving file without proxy entries, precheck tool shows success for Yum Proxy Check probe. Sample screenshot for the same:
