Vulnerability discussion

The daytime service runs as root from the inetd daemon and can provide an opportunity for Denial of Service PING or PING-PONG attacks. The daytime service is unnecessary and it increases the attack vector of the system.

Check content

Fix text

Edit /etc/inetd.conf and comment out daytime service lines for both TCP and UDP protocols. Restart the inetd service. # refresh -s inetd

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.
