Malware Scan failure to scan files

Problem

Malware scanner installed on Linux fails to scan files, producing either of the following errors in the WebUI.

Error Message

VxUL oid=518,id=11

Failed to get response from NetBackup malware utility

Cause

During installation of the Malware Scanner software, /tmp does not have execute permissions and fails to properly install all packages.

journalctl -f shows the following failure:

Solution

Mount /tmp as executable. This should be done by the customer's Linux admin. 

# sudo mount -o remount,exec /tmp
