NAME
syslogd - log systems messagesSYNOPSIS
syslogd [-V ] [-a socket ] [-d ] [-f config_file ] [-h ] [-l host_list ] [-m mark_interval ] [-n ] [-p log_socket ] [-r ] [-s domain_list ] [--no-klog ] [--no-unixaf ] [--no-forward ]DESCRIPTION
Syslogd reads and logs messages to the system console, log files, other machines and/or users as specified by its configuration file. The options are as follows:- -V
- Print version number and exit.
- --help
- Display help information and exit.
- -d
- Enter debug mode. syslogd does not put itself in the background, does not fork and shows debug information.
- -a
- Specify additional sockets from that syslogd has to listen to. This is needed if you are going to let some daemon run within a chroot()'ed environment. You can specify up to 19 additional sockets.
- -f, --rcfile=FILE
- Specify the pathname of an alternate configuration file; the default is system specific and displayed in the help output.
- --rcdir=DIR
- Specify the pathname of an alternate configuration directory; the default is system specific and displayed in the help output.
- -h, --hop
- Enable forwarding remote messages. By default syslogd will not forward messages it receives from remote hosts.
- -l
- A colon-seperated lists of hosts which should be considered local; they are logged by their hostnames instead by their FQDN.
- -m, --mark=INTERVAL/fP
- Select the number of minutes between ``mark'' messages; the default is 20 minutes. Setting it to 0 disables timestamps.
- -n, --no-detach
- Suppress backgrounding and detachment of the daemon from its controlling terminal.
- -p, --socket=PATH
- Specify the pathname of an alternate log socket. The default is systemspecific and displayed in the help output.
- -r, --inet
- Enable to receive remote messages using an internet domain socket. The default is to not receive any messages from the network. Older version always accepted remote messages.
- -s
- A colon-seperated list of domainnames which should be stripped from the FQDNs of hosts when logging.
- --no-klog
- Do not listen to the kernel log device. This is only supported on systems which define a kernel log device, on all others this is already the default, and the option will be silently ignored.
- --no-unixaf
- Do not listen to any unix domain socket. This option overrides -p and -a.
- --no-forward
- Do not forward any messages. This overrides -h.
Syslogd reads its configuration file when it starts up and whenever it receives a hangup signal. For information on the format of the configuration file, see syslog.conf5.
Syslogd reads messages from the UNIX domain socket /dev/log from an Internet domain socket specified in /etc/services and from the one of the special devices /dev/klog or /proc/kmsg depending on the system (to read kernel messages). In a GNU/Linux system it will not parse the System.map and use it to annotate the kernel messages.
Syslogd creates the file /var/run/syslog.pid and stores its process id there. This can be used to kill or reconfigure syslogd
The message sent to syslogd should consist of a single line. The message can contain a priority code, which should be a preceding decimal number in angle braces, for example, `Aq 5. ' This priority code should map into the priorities defined in the include file Aq Pa sys/syslog.h .
