|

| 12 | The syslogd utility is used to record logs of all the
|
|---|
| 13 | significant events that occur on a system. Every
|
|---|
| 14 | message that is logged records the date and time of the
|
|---|
| 15 | event, and will generally also record the name of the
|
|---|
| 16 | application that generated the message. When used in
|
|---|
| 17 | conjunction with klogd, messages from the Linux kernel
|
|---|
| 18 | can also be recorded. This is terribly useful,
|
|---|
| 19 | especially for finding what happened when something goes
|
|---|
| 20 | wrong. And something almost always will go wrong if
|
|---|
| 21 | you wait long enough....

| 36 | When you enable this feature, the syslogd utility can
|
|---|
| 37 | be used to send system log messages to another system
|
|---|
| 38 | connected via a network. This allows the remote
|
|---|
| 39 | machine to log all the system messages, which can be
|
|---|
| 40 | terribly useful for reducing the number of serial
|
|---|
| 41 | cables you use. It can also be a very good security
|
|---|
| 42 | measure to prevent system logs from being tampered with
|
|---|
| 43 | by an intruder.

|
|---|
| 50 | When you enable this feature, the syslogd utility will
|
|---|
| 51 | use a circular buffer to record system log messages.
|
|---|
| 52 | When the buffer is filled it will continue to overwrite
|
|---|
| 53 | the oldest messages. This can be very useful for
|
|---|
| 54 | systems with little or no permanent storage, since
|
|---|
| 55 | otherwise system logs can eventually fill up your
|
|---|
| 56 | entire filesystem, which may cause your system to
|
|---|
| 57 | break badly.

|

|

| 104 | messages to the system log (i.e. the 'syslogd' utility) so
|

| 105 | they can be logged. This is generally used to help locate
