This package in fact implements two system log daemons. The syslogd daemon is an enhanced version of the standard Berkeley utility program. This daemon is responsible for providing logging of messages received from programs and facilities on the local host as well as from remote hosts.

The klogd daemon listens to kernel message sources and is responsible for prioritizing and processing operating system messages. The klogd daemon can run as a client of syslogd or optionally as a standalone program. Klogd can now be used to decode EIP addresses if it can determine a System.map file.
