We provide Command Line Interface (CLI), the name is LYSH, which is used for configuring, monitoring, and maintaining the imRAD devices. The CLI allows you to directly execute commands, whether using a console(i.e. Serial Communication) or using remote access methods such as Secure Shell (SSH, port 22).
The imRAD device does not allow telnet access.
If you access the console port, the port is located in front of the device and the type is RJ45 connector. And then, configure the terminal emulation software on your PC for 115,200 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
The default or initial Username and Password are ladmin and 1111 respectively.
If you log in with the default, you must change the default password. If not, you can't access the CLI before changing the password.
The CLI has two command line modes: user mode and configuration mode. By default, user mode is where you begin the session with the imRAD devices. The user mode contains commands that you can use to see logs, the status of services, configurations, system variables and information, and so on. You can run some Linux commands in user mode.
The configuration mode enables to have you can do changes on device configuration such as hostname, Database properties, IP address, nameserver, tiemzone, ntp, ufw, failover, etc. To enter the configuration mode, type the configure command in the user mode.
If press the <tab> key at any time, you can complete the command or see the argument of the command, You can also display "help" by input -h or --help at the end of every command,
LYSH@MyHostName# show -h
usage: show [-h] {apache2,command,config,datetime,dci,files,failover,hardware,interface,listen,log,
loghost,multicast,mysql,ntp,php,service,session,system,uptime} ...
show the system information
positional arguments:
apache2 show the status of apache2 service
command show all or related commands
config show config files
datetime show current time and zone
.....
If you want to see all commands, enter the show command in the user mode. If you want to find specific commands which include the keyword, enter the show command {keyword}. It shows all commands which contain the keyword.

if you execute show command --linux command, you can see allowed Linux commands.
Note that you can not execute commands that are not allowed such as rm, vi, and so on.
