The cost of components is relatively low a 10-euro/dollar project if one uses “eBay-grade” parts (which are likely sufficient).
Console access to the bootloader will often allow one to fetch and flash new firmware and may be the only way to do so on some routers if the firmware is not functional.Įnabling a serial port, if there is not one already available on the case, typically involves opening the case and basic soldering skills. A console to the running system will let you correct a misconfigured network, for example. These serial ports typically provide a console to the bootloader and, when the firmware has booted, a console to the running system. Most devices supported by OpenWrt have or can be modified to have a serial port. However, some bootloaders don't have a “really failsafe” network re-flash feature, making a serial console one of the few ways to recover from a “bad flash” or an error in a user's own configuration. Profile (Default/Power C37.238/Telecom G.8275.Most people get along without a serial console for their device because they're able to flash a working firmware the first time - or are able to apply various recovery methods - and do all their communicating with the device over a network.

The overview tab offers an overview of all simulation groups, current simulations and their statistics, that are created on the currently connected simulation services.Ħ4 bit Linux Mint Live system (included in scope of delivery). Additionally you can save and look at simulation statistics. Simulation groups can be created, edited or deleted and started or stopped individually. because it is in a seperate subnet, you can manually establish a direct connection by using the text field "Manual Remote Connection".Īfter having successfully established a connection to a simulation service you can control the simulation via the connection tab. If one of the services does not appear automatically, i.g. If you posses several licenses, you can simultaneously control several simulation services from the same computer. In the main tab of the Remote Control Interface you will find an overview of the current simulation services in the network. This is to make sure that the simulation service is started automatically and is ready for remote control, even without user identification If no mode was selcted the system will automatically start in the desktop mode, after a short while.
For all other purposes the terminal mode is sufficient. If you want to control the simulation from the same computer or server, the desktop mode is recommended. In the boot menu of the USB Live-System you may choose between desktop mode and terminal mode. The software allows you to create a few network nodes for a basic interoperability test of your implementation, as well as performance tests of your network by a mass simulation of devices, without the need of installing these devices for the test. By booting the Live-System all data on your computer or server will not be changed, which means that your hardware is only transformed into a flexible and functional NTP-/PTP-simulator for the duration of the simulation and can be used as before after the simulation.
The second USB stick provides a license key and has to be inserted into the simulationsystem during the simulation, to have access to the complete functionality of the software. The simulation can now be controlled either from the same system or from a remote computer. The delivery contains two USB sticks: One of the USB sticks can be used to boot a Live-Linux-System, on which the simulation service is started automatically after successful booting procedure, on any computer or server.
