One can get the router’s information through SMS or using RMS (Remote Management System). Furthermore, some system related parameters can be obtained using MQTT or MODBUSD publisher services. The main focus is on parameters, which change from time to time, like signal strength, operator’s name (it is quite common to change the mobile operator’s name in countries where inner roaming is used) or module temperature. Although it is also possible to read static values, like MAC address, router’s serial number and many others. The access to the mentioned parameters is implemented in both MODBUSD and MQTT publisher applications. Apart from getting parameters, MODBUSD can also be used to set some system related parameters, for example, it can be used to change the value of the digital output.

Some applications, like MQTT publisher or RMS, allow monitoring or administrating several routers at once. It is a very useful functionality when you want to change the same parameters on more than one router at once. RMS shares some similarities with SSH (Secure Shell) and one of RMS features is to allow SSH access to a remote router. You can access RMS by using your browser with a supplied username and a password at http://rms.teltonika.lt

By sending SMS messages to the router the user can execute various commands like reboot, switch Wi-Fi on or off and many others. With each SMS the user needs to specify the router’s administrator password. This is done for authentication purposes. The list of commands that may be executed through SMS is limited. Full list of commands can be found at Services->SMS Utilities of the router’s WEB page. In theory SMS can be used to manage multiple routers as well by implementing SMS Forwarding to SMS to the mix.

Another interesting router monitoring solution is SNMP (Simple Network Management Protocol). By not going into deep detail about this protocol, it is another manner to monitor router parameters. It allows the user to check the current operator, modem model and other router parameters. Compared to other applications and services, only SNMP has ability to inform the user about the occurrence of specific events (called traps) in the system. The main drawback of this protocol is that it does not allow the user to change anything.

Apart from the services mentioned already, there is one service, which is used only for communication between the router and an Android type device (phones, etc.). It is called JSON-RPC and it allows the user to set or get various parameters of the system. JSON-RPC provides users with the possibility to execute the same commands as they would through SSH. To sum up, this approach opens up wide possibilities in communication between the router and an Android device.

Each approach has its advantages and disadvantages. In some situations MQTT publisher works better than MODBUSD, while in others MODBUSD will be the better choice. The most versatile manner of system monitoring and administration is through SSH. SSH provides complete control of the router. The user can execute commands, write shell scripts and do many other things. In this case, the user only needs an application to connect to the router through SSH. The most popular application used in Windows type operating systems is called Putty. If one is trying to connect to the router from a UNIX type operating system, all that is needed is the hostname, username (in this case – root) and password.

Sometimes the use of SSH is not necessary, so other more conservative services/applications are used. The complete list of applications and services that can be used for router administration and monitoring is given below. It can be seen that all applications, except MQTT publisher and SNMP, support both setting and getting of some system related parameters.

APPLICATION	CAN OBTAIN PARAMETERS	CAN SET PARAMETERS
MQTT publisher	yes	no
MODBUS daemon	yes	yes
SSH	yes	yes
RMS	yes	yes
SMS	yes	yes
SNMP	yes	no
JSON-RPC	yes	yes
TR-069	yes	yes

To summarize, RUT955 provides several solutions for remote router management. Each user can choose what solution suits them the best. If the required functionality is not supported by a particular service, the user can combine several applications, for example, use MQTT publisher along with SNMP. Finally, if a user has special needs, he can write shell scripts and execute them via SSH or use JSON-RPC.
