Vulnerability discussion

IP tunneling mechanisms can be used to bypass network filtering.

Check content

Check for any IP tunnels. # ifconfig -a | grep 'ip.*tun' If any results are returned, this is a finding.

Fix text

Disable the tunnels. # ifconfig down Remove the startup configuration for the tunnels. # rm /etc/hostname.

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.
