is there any way to check if the plugin is working in telnet ?
Its not a plugin, but more like a modified version of oscam you`ve installed.
If you`ve followed the instructions properly it will have created a bouquet for those channels (press the TV button for bouquets)
You`ve been provided oscam config files, so you must be able to look at the oscam webinterface to check if its working. webinterface details will be in oscam.conf [webif}]
