help
|

The syslogd utility is used to record logs of all the
|

significant events that occur on a system. Every
|
||||
message that is logged records the date and time of the
|
||||
event, and will generally also record the name of the
|
||||
application that generated the message. When used in
|
||||
conjunction with klogd, messages from the Linux kernel
|
||||
can also be recorded. This is terribly useful,

especially for finding what happened when something goes

When you enable this feature, the syslogd utility can
|

be used to send system log messages to another system
|

connected via a network. This allows the remote
|
||||
machine to log all the system messages, which can be
|

terribly useful for reducing the number of serial

When you enable this feature, the syslogd utility will

use a circular buffer to record system log messages.
|
||||
When the buffer is filled it will continue to overwrite
|
||||
the oldest messages. This can be very useful for
|

systems with little or no permanent storage, since

otherwise system logs can eventually fill up your

The klogd applet supports two interfaces for reading

independently from the file system.

If you answer 'N' here, klogd will use the more portable

approach of reading them from /proc or a device node.
