Because the Avahi daemon service keeps an open network port, it is subject to network attacks. Its functionality is convenient but is only appropriate if the local network can be trusted.
To check that the "avahi-daemon" service is disabled in system boot configuration, run the following command: # chkconfig "avahi-daemon" --list Output should indicate the "avahi-daemon" service has either not been installed, or has been disabled at all runlevels, as shown in the example below: # chkconfig "avahi-daemon" --list "avahi-daemon" 0:off 1:off 2:off 3:off 4:off 5:off 6:off Run the following command to verify "avahi-daemon" is disabled through current runtime configuration: # service avahi-daemon status If the service is disabled the command will return the following output: avahi-daemon is stopped If the service is running, this is a finding.
The "avahi-daemon" service can be disabled with the following commands: # chkconfig avahi-daemon off # service avahi-daemon stop
Lavender hyperlinks in small type off to the right (of CSS
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
