Discussion

Limiting the number of established connections is a basic denial-of-service protection and a best practice. Servers where the limit is too high or unlimited could run out of system resources and negatively affect system availability.

Check Content

At the command prompt, run the following command:

# xmllint --xpath '/Server/Service/Connector[@port="${bio-custom.http.port}"]/@acceptCount' /usr/lib/vmware-lookupsvc/conf/server.xml

Expected result:

acceptCount="100"

If the output does not match the expected result, this is a finding.

Fix Text

Navigate to and open:

/usr/lib/vmware-lookupsvc/conf/server.xml

Navigate to the <Connector> configured with port="${bio-custom.http.port}".

Add or change the following value:

acceptCount="100"

Restart the service with the following command:

# vmon-cli --restart lookupsvc
