System configuration /etc/config/system

The system UCI subsystem configuration file is located in /etc/config/system.

System section

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:

root@lede:/# uci show system
root@lede:/# cat /etc/config/system
config 'system'
	option 'hostname'	'OpenWrt'
	option 'timezone'	'UTC'

These options can be set in the system section:

Name Type RequiredDefault Description
hostname string no OpenWrt 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 specificSize 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 verbose messages in console put conloglevel to 8 if you want less messages lower conloglevel to 4 or even less.
Note that in releases 17.x and later this and similar parameters may have no effect.
See, for example.
cronloglevel integer no 5 The minimum 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_hostname stringno (none) Hostname to send to remote syslog. If none is provided, the actual hostname is send. This feature is only present in 17.xx and later versions
log_ip IP addressno (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_nullbool no 0 Use \0 instead of \n as trailer when using TCP.
log_type string no circular Either circular or file.
urandom_seed string no 0 Path of the seed. Enables saving a new seed on each boot.
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! FIXME: Is this really true? IIRC musl supports zoneinfo as well (but the zoneinfo packages are still needed) at least for 17.xx and later series (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 *)
