System configuration
====================

== System configuration

The system UCI configuration is located in **'/etc/config/system'**.

== Sections

The 'system' configuration contains basic settings for the whole router. Larger subsystems such as the network configuration, the DHCP and DNS server, and similar, have their own configuration file.

=== System

The 'system' section contains settings that apply to the most basic operation of the system, such as the hostname, the time zone, and how and where to write logging information to. The default settings are:

----
config 'system'
	option 'hostname'	'lede'
	option 'timezone'	'UTC'
----

These options can be set in the system section:

[cols="4*1,4",options="header"]
|====
| Name | Type | Required | Default | Description
| 'hostname' | string | no | 'lede' | The hostname for this system. Avoid points, even if they are within quotes. For example ' 'my.hostname' ' will show only the ' 'my' ' part
| 'buffersize' | integer | no | kernel specific | Size of the kernel message buffer.
| 'conloglevel' | integer | no | '7' | Number between 1-8. The maximum log level for kernel messages to be logged to the console. Only messages with a level lower than this will be printed to the console. Higher level messages have lower log level number. Highest level messages are ones with log level 0. If you want more verbous messages in console put conloglevel to 8 if you want less messages lower conloglevel to 4 or even less.
| 'cronloglevel' | integer | no | '5' | The minimul level for cron messages to be logged to syslog. '0' will print all debug messages, '8' will log command executions, and '9' or higher will only log error messages.
| 'klogconloglevel' | integer | no | '7' | The maximum log level for kernel messages to be logged to the console. Only messages with a level lower than this will be printed to the console. Identical to 'conloglevel' and will override it.
| 'log_buffer_size' | integer | no | 16 | Size of the log buffer of the "new" procd based system log, that is output by the  _logread_ command. Tried 32 kB, more should be possible.
| 'log_file' | string | no | no log file | File to write log messages to (type 'file'). The default is to not write a log in a file. The most often used location for a system log file is '/var/log/messages'.
| 'log_ip' | IP address | no | _(none)_ | IP address of a syslog server to which the log messages should be sent in addition to the local destination.
| 'log_port' | integer | no | '514' | Port number of the remote syslog server specified with 'log_ip'.
| 'log_prefix' | string | no |_(none)_| Adds a prefix to all log messages send over network.
| 'log_proto' | string | no | 'udp'| Sets the protocol to use for the connection, either 'tcp' or 'udp'.
| 'log_remote' | bool | no | '1' | Enables remote logging.
| 'log_size' | integer | no | '16' | Size of the file or circular memory buffer in KiB.
| 'log_trailer_null' | bool | no | '0' | Use \0 instead of \n as trailer when using TCP.
| 'log_type' | string | no | 'circular' | Either 'circular' or 'file'.
| 'timezone' | string | no | 'UTC' | The time zone that date and time should be rendered in by default.
| 'zonename' | string | no | 'UTC' | Only useful when using glibc and zoneinfo! ('LIBC_USE_EGLIBC', 'PACKAGE_zoneinfo-*') The time zone that date and time should be rendered in by default. Suppose you want to use Brussels' timezone, set this value to 'Europe/Brussels'. Possible values can be found by running '(cd /usr/share/zoneinfo; find *)'
|====

=== Remote Time (ntp)

| {{:meta:icons:tango:48px-outdated.svg.png?nolink}}  | In '/etc/config/system' 'busybox-rdate' (was invoked by scripts) has been replaced with 'busybox-nptd' (can run as a daemon) to avoid race condition and also to use current NTP. The remote time is since configured in '/etc/config/system' and not in '/etc/config/timeserver' any longer.

* WARNING:  Old scripts first checked if a lease time server is defined for the interface in the network config.
* WARNING:  If not available or syncing fails, then it searches for time servers in the timeserver config that are either explicitly defined for that interface or via the global setting in the system config.

----
config 'timeserver' 'ntp'
	list 'server'     '0.openwrt.pool.ntp.org'
	list 'server'     '1.openwrt.pool.ntp.org'
	list 'server'     '2.openwrt.pool.ntp.org'
	list 'server'     '3.openwrt.pool.ntp.org'
	option enable_server 0
----

There are at least two valid option defined for the 'timeserver' 'ntp' section:

[cols="4*1,4",options="header"]
|====
| Name | Type | Required | Default | Description
| 'server'        | list of hostnames | no | _(none)_ | Defines the pool of NTP servers to poll the time from. If the list is empty, the builtin NTP daemon is not started.
| 'enable_server' | boolean           | no |  0  | You can put busybox-ntpd in\\ client mode only: by defining at least one host to 'server' and puting 'enable_server' 0 \\ client & server mode: by putting 'enable_server' to 1, (busybox-ntpd listens to UDP 123 by default),\\ server mode only: by not defining any servers in the config and just put 'enable_server' 1 (ntpd will answer with the time of the router)
|====

=== Leds

LEDs are represented by entries in the 'sys' filesystem. You can check which LEDs are available in the '/sys/class/leds' directory. The name of an entry typically consists of the name of the hardware providing the LED (the router model), the color of the LED, and it's designation (usually the label on the case). Some LEDs can show different colors. In this case, you will find one entry per color.

The LED can be controlled by various events in the system, which is selected by the 'trigger' option. Depending on the trigger, additional options must be specified.

First of all, you need to know which triggers are available for a led, to do that simply look at the 'trigger' file of that led. Example:

----
cat /sys/class/leds/**LED**/trigger
[none] timer default-on netdev morse usbdev
----

=== None ===

The LED is always in default state. Unlisted LED are default OFF, so this is only useful to declare a LED to be always ON.

[cols="4*1,4",options="header"]
|====
| Name | Type | Required | Default | Description
| 'default' | integer | no | 0 | LED state before trigger: '0' means OFF and '1' means ON
| 'sysfs' | string | yes | _(none)_ | LED device name
| 'trigger' | string | yes | _(none)_ | 'none'

The LED flashes on events triggered in physical interface, rather than in software network interface. Besides 'phy'
triggers have more events, it also provides possibility of static LED setup in case you want to monitor your 2.4 GHz
radio ('phy0' usually) and 5 GHz radio ('phy1' usually) separately. 'netdev' can't guarantee this distinguishing
since 'wlan0' may be referring to 2.4 GHz or 5 GHz radio based on current network setup.
