Vulnerability discussion

To provide some mitigation to TCP DoS attacks, the clear_partial_conns parameter must be enabled.

Check content

# /usr/sbin/no -o clean_partial_conns If the value returned is 0, this is a finding.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
