This section provides a list of all available configuration files of RUT routes.
This section provides a list of all available configuration files of RUT routers. Note that these are all possible config files from any RUT router ([[RUT230]], [[RUT240]], [[RUT850]], [[RUT950]], [[RUT955]]) and that therefore some of them may not exist in your router.

This section will overview uci get and uci show commands used to obtain router parameters as well as provide some basic knowledge on configuration hierarchy needed to successfully use most uci commands.
This section will overview uci get and uci show commands used to obtain router parameters, option and section names and contents of entire configs or sections.

The command above returns the Wi-Fi Access Point's SSID. As you can see the <span style=color:purple>uci get</span> command is used. What follows after the command is the path to the value that we're looking for (SSID, in this case). The SSID value can be found in the <span style=color:red>wireless</span> config, the <span style=color:blue>@wifi-iface[0]</span> section, stored in an option called <span style=color:green>ssid</span>. So the basic syntax for a uci get command is this:

[[File:Uci show wireless response v2.png]]
[[File:Uci show wireless response v2.png]]
As you can see, this time the response shows the entire wireless config and instead of just showing values (like in the case of uci get) you can see the config name, section name and option name before each one.
As you can see, the response shows the entire wireless config and its entities. Note that instead of just showing values (like in the case of uci get) you can see the config name, section name and option name before each one.
Most config file names are simple. Wireless config is called wireless, OpenVPN config is called openvpn, etc. But even so one doesn't necessarily have to know what a config file is called, especially before interacting with it. To see the names of all config files and what kind of settings they store you can refer to the '''[[UCI_command_usage#Configuration_files|table above]]'''. Or if you're CLI or SSH and want to check the names of config files on the spot, you can use the '''ls''' command. Since RUT configs ar stored in '''/etc/config''', the full commands should look like this:

So when you plan on obtaining specific parameters or setting parameter values, you should always start with finding out option and section names. To accomplish this, we recommend using the uci show <config> commands.

As you may have noticed, the command is very similar to uci get, except it has an equals to (''''='''') sign added at the end and after the sign is the value that we want to assign to the option.

The next step is to commit the changes by using the '''uci commit''' command and to restart all the services relevant to our configuration by using the '''luci-reload''' command:
The next step is to commit the changes by using the '''uci commit''' command and to restart all the services relevant to our configuration by using the '''/etc/init.d/wireless restart''' command:
# uci commit wireless
# uci commit wireless
# luci-reload
# /etc/init.d/wireless restart
After this, your changes will be applied and in use. Notice that when using uci commit you can specify the config file for which you want to commit changes (you can even specify the exact section and option). This is useful when making changes to multiple options in case you make any mistakes, because before committing any changes you can easily undo them with the '''uci revert''' command. The command by itself will undo all the changes made by uci up until the last commit. It can also be used on specific config files, sections and options in order to undo specific changes.

Some variables hold more than one value unlike options. These variables are called '''lists'''. For example, if you use MAC filter on your Wi-Fi Acsess point, the MAC addresses are saved not as options but as a list.

Notice that you have to use a separate command for adding each value and as with uci set you have to use uci commit and luci-reload in order for the changes to take effect.

With all that we have learned lets try a more complicated example: lets you want to create an OpenVPN server. The server will be called '''MyServer''', will use a '''TUN''' type interface and '''TLS''' authentication. In order to create this server we will first have to create a section for the server in the openvpn config:

The first-third steps add hostnames of the websites to be blocked, which are saved under the option ''host''. Each of the first three elements also need to be enabled, therefore, the option ''enabled'' is set to ''1'' next to each host. The fourth step is for enabling the Site Blocking service (by setting the option ''enabled'' in section ''config'' to ''1'').

This example will provide instructions on how configure RUT routers' DHCP Server using only. For the sake of the example lets say that you want to change the dhcp range to ''192.168.1.2'' - ''192.168.1.200'' and the lease time to ''30 minutes''

To achieve such a task, the first relevant piece of required information is the config name, '''dhcp''', where all the necessary configuration settings are stored. Another important thing to know is that when changing the lease time, three options are relevant - the time (option ''time''), the unit of time measurement (option ''letter'') and lease time(option ''leasetime), which is basically ''time'' ''+'' ''letter'', e.g., 12 hour lease time is ''12h''. Other options in question are start address (option ''start'') and address limit (option ''limit''). Lets start:

# /etc/init.d/dhcp restart
The first step sets the start address to 2 and the limit of addresses to 199. The value of the ''start'' option is associated with the last section of an IP address (if start value is '''2''' then the starting IP address is 192.168.1.'''2'''(provided that the router's LAN IP is in the 192.168.1.0/24 network)), the value of the ''limit'' option denotes how many IP addresses can be leased out starting from and including the the start address. Then the second step is used to set the lease time. The ''letter'' option specifies the unit of time measurement (either ''m'' for minutes or ''h'' for hours). The ''time'' option specifies number of minutes (or hours in other cases) and the ''leasetime'' option is just the representation (nonetheless, it's still mandatory) of the previous two values, i.e., 30m - thirty minutes.

===Mobile Data Limit===
----
This example will provide instructions on how configure Mobile Data Limit and SMS Warning on RUT routers' using only UCI commands. For the sake of the example lets say that you want to set up a data limit of 1 GB with the limit counter restarting everyday at 10 a.m. and an SMS Warning that sends out a message when the 800 MB threshold is reached that also restarts everyday at 10 a.m.
To achieve such a task, the first relevant piece of required information is the config name, '''quota_limit''', where all the necessary configuration settings are stored:
Enabling Mobile Data Limit and SMS Warning:
# uci set quota_limit.mob1s1a1=interface
# uci set quota_limit.mob1s1a1.enabled='1'
# uci set quota_limit.mob1s1a1.ifname='mob1s1a1'
# uci set quota_limit.mob1s1a1.reset_hour='10'
# uci set quota_limit.mob1s1a1.sim='1'
# uci set quota_limit.mob1s1a1.data_limit='10000'
# uci set quota_limit.mob1s1a1.enable_warning='1'
# uci set quota_limit.mob1s1a1.period='1'
# uci set quota_limit.mob1s1a1.warning_limit='8000'
# uci set quota_limit.mob1s1a1.warning_num='+37012345678'
Commit changes and restart the daemon
# uci commit quota_limit
# /etc/init.d/quota_limit restart
'''Disabling / Deleting configuration'''
-----
Let us take the above example and disable the data limit using '''uci'''. For this, we simply need to change the "enabled" value to '0':
# uci set quota_limit.mob1s1a1.enabled='0'
# uci commit quota_limit
# /etc/init.d/quota_limit restart
If you wish to delete the whole configuration, '''uci delete''' can be used. Let us delete the entire block of configuration of mob1s1a1 interface:
# uci delete quota_limit.mob1s1a1
# uci commit quota_limit
# /etc/init.d/quota_limit restart
