|

| 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

| 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

|

| 124 | The klogd applet supports two interfaces for reading
|
---|
| 125 | kernel messages. Linux provides the klogctl() interface
|

|

| 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.
