8 Remote monitoring and administration

RUT955 supports multiple monitoring and administration possibilities. One can get 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. Instruction on how to use them can be found in
document respectively. The main focus is on parameters, which change from time to time, like signal strength,
operator's name (it is quite common to change 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. There is no
separate chapter about RMS in this manual, because the interface of RMS is very intuitive and user friendly. You can
access RMS by using your browser with a supplied username and a password at
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. More information on how to manage the router using SMS
can be found in chapter 9.8
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. You can read more about SNMP in chapter 9.9.
Apart from the services mentioned earlier, 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. However, there is no separate topic about JSON-RPC in this manual, because this type of
communication is generally not for end-user use.
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 such 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 setting/getting of some system related
parameters.
