14 | The syslogd utility is used to record logs of all the
|
---|
15 | significant events that occur on a system. Every
|
---|
16 | message that is logged records the date and time of the
|
---|
17 | event, and will generally also record the name of the
|
---|
18 | application that generated the message. When used in
|
---|
19 | conjunction with klogd, messages from the Linux kernel
|
---|
20 | can also be recorded. This is terribly useful,
|
---|
21 | especially for finding what happened when something goes
|
---|
22 | wrong. And something almost always will go wrong if
|
---|
23 | you wait long enough....

38 | When you enable this feature, the syslogd utility can
|
---|
39 | be used to send system log messages to another system
|
---|
40 | connected via a network. This allows the remote
|
---|
41 | machine to log all the system messages, which can be
|
---|
42 | terribly useful for reducing the number of serial
|
---|
43 | cables you use. It can also be a very good security
|
---|
44 | measure to prevent system logs from being tampered with
|
---|
45 | by an intruder.

|

69 | help
|
---|
70 | When you enable this feature, the syslogd utility will
|
---|
71 | use a circular buffer to record system log messages.
|
---|
72 | When the buffer is filled it will continue to overwrite
|
---|
73 | the oldest messages. This can be very useful for
|
---|
74 | systems with little or no permanent storage, since
|
---|
75 | otherwise system logs can eventually fill up your
|
---|
76 | entire filesystem, which may cause your system to
|

77 | break badly.

93 | If you enabled Circular Buffer support, you almost
|

94 | certainly want to enable this feature as well. This

102 | help

103 | 'logread' ouput to slow serial terminals can have

104 | side effects on syslog because of the semaphore.

113 | klogd is a utility which intercepts and logs all
|
---|
114 | messages from the Linux kernel and sends the messages
|
---|
115 | out to the 'syslogd' utility so they can be logged. If
|

116 | you wish to record the messages produced by the kernel,

117 | you should enable this option.

123 | help
|

124 | The klogd applet supports two interfaces for reading
|
---|
125 | kernel messages. Linux provides the klogctl() interface
|
---|
126 | which allows reading messages from the kernel ring buffer
|
---|
127 | independently from the file system.
|
---|
128 |
|
---|
129 | If you answer 'N' here, klogd will use the more portable
|
---|
130 | approach of reading them from /proc or a device node.
|
---|
131 | However, this method requires the file to be available.

140 | The logger utility allows you to send arbitrary text
|

141 | messages to the system log (i.e. the 'syslogd' utility) so
|
---|
142 | they can be logged. This is generally used to help locate
|

143 | problems that occur within programs and scripts.
